    In the Alps infrastructure facilities such as roads, routes or buildings are affected by the changes of permafrost, which often cause enormous reparation costs. Investigation on degradation of Alpine Permafrost in the last decade has increased, however, the understanding of the permafrost changes inducing its atmospheric forcing processes is still insufficient. Within the project ATMOperm the application of the geoelectrical method to estimate thawing layer thickness for mountain permafrost is investigated near the highest meteorological observatory of Austria on the Hoher Sonnblick. Therefore, it is necessary to further optimize the transformation of ERT data to thermal changes in the subsurface. Based on an innovative time lapse inversion routine for ERT data (Kim J.-H. et al 2013) a newly developed data analysis software tool developed by Kim Jung-Ho (KIGAM) in cooperation with the Geophysics group of the Geological Survey of Austria allows the statistical analysis of the entire sample set of each and every data point measured by the geoelectrical monitoring instrument. This gives on the one hand of course an enhanced opportunity to separate between „good" and „bad" data points in order to assess the quality of measurements. On the other hand, the results of the statistical analysis define the impact of every single data point on the inversion routine. The interpretation of the inversion results will be supplemented by temperature logs from selected boreholes along the ERT profile as well as climatic parameters.

    The estimation of catchment-scale rockfall rates relies on the regionalisation of local measurements. Here, we propose a new framework for such a regionalisation by the example of a case study in the Upper Kaunertal, Austrian Central Alps (62.5 km2). Measurements of rockfall deposition during 12 months onto six collector nets within the study area were combined with published mean annual rates from the literature, and a probability density function was fitted to these data. A numerical model involving a random walk routing scheme and a one-parameter friction model was used to simulate rockfall trajectories, starting from potential rockfall source areas that were delineated from a digital elevation model. Rockfall rates sampled from the fitted probability density function were assigned to these trajectories in order to model the spatial distribution and to estimate the amount of rockfall deposition. By recording all trajectories as edges of a network of raster cells, and by aggregating the latter to landforms (or landform types) as delineated in a geomorphological map of the study area, rockfall sediment flux from sources to different landforms could be quantified. Specifically, the geomorphic coupling of rockfall sources to storage landforms and the glacial and fluvial sediment cascade was investigated using this network model. The total rockfall contribution to the sediment budget of the Upper Kaunertal is estimated at c. 8000 Mg yr- 1, 16.5% of which is delivered to the glaciers, and hence to the proglacial zone. The network approach is favourable, for example because multiple scenarios (involving different probability density functions) can be calculated on the basis of the same set of trajectories, and because deposits can be back-linked to their respective sources. While the methodological framework constitutes the main aim of our paper, we also discuss how the estimation of the budget can be improved on the basis of spatially distributed production rates.

    The formation of lakes is one of the consequences of glacier retreat due to climate change in mountain areas. Numerous lakes have formed in the past few decades in many mountain regions around the globe. Some of these lakes came into focus due to catastrophic hazard events especially in the Himalayas and the Andes. Glacial lake development and lifetime is controlled by the complex interplay of glacier dynamics, geomorphological process activity and geological boundary conditions. Besides the hazard potential new lakes in formerly glaciated areas will significantly contribute to a new landscape setting and to changing geomorphologic, hydrologic and ecologic conditions at higher alpine altitudes. We present an inventory of high alpine lakes in the Austrian Alps located above an altitude of 1700 m asl. Most of these lakes are assumed to be of glacial origin, but other causes for development, like mass movements are considered as well. The inventory is a central part of the project FUTURELAKES that aims at modelling the potential development of glacial lakes in Austria (we refer to the presentation by Helfricht et al. during the conference for more details on the modelling part). Lake inventory data will serve as one basis for model validation since modelling is performed on different time steps using glacier inventory data. The purpose of the lake inventory is to get new insights into boundary conditions for lake formation and evolution by analysing existing lake settings. Based on these information the project seeks to establish a model of lake sedimentation after glacier retreat in order to assess the potential lifetime of the new lakes in Austria. Lakes with a minimum size of 1000 m² were mapped using multiple aerial imagery sources. The dataset contains information on location, geometry, dam type, and status of sedimentation for each lake. Additionally, various geologic, geomorphic and morphometric parameters describe the lake catchments. Lake data is related to

    Austria has the highest national added value from winter tourism in Europe, as well as worldwide. 15.7 million arrivals were counted in Austrian accommodation establishments in the 2010/11 winter season. There were more than 62 million overnight stays and 51.2 million skier-days were consumed. 588 million transports were carried out by more than 3000 lifts (cable cars, chair lifts and T-bars). Including indirect and induced effects, this resulted in more than 10 billion euros in added value being generated. The lack of snow in many Austrian skiing areas during the 2006/2007 winter season demonstrated the extent to which meteorological conditions influence operations. Declines in the number of skiers transported and total skier days were the result. The cable-car operators also had to struggle with little snow in the 2010/2011 winter. The Austrian Cable Car Operators' Association stated that the opening of 70-80% of all skiing areas outside of the peak season could only be assured through the use of snowmaking equipment. The central criterion for winter sports enthusiasts to make a trip is the guarantee that they will find snow at their destination and Austria's cable-car operators invest more than 100 million euros in the erection and improvement of snowmaking complexes every year to satisfy this deand. In the 2010/2011 season, this provided for 17,800 jobs. Cable car operators set up snowmaking equipment to become independent from meteorological conditions and improve the capacity utilisation of their expensive investments in transport systems in the early winter. Austria has a skiing area of around 25,400 hectares - around 17,000 hectares at altitudes between 600m and 3200m are currently suitable for snowmaking. As much as 70% of the snow is produced immediately before the start of the season. This recent trend is responsible that the irrigation pattern of Austrian land use changed significantly in the last decade. Previously maize fields and low lands in summer

    Full Text Available Ecosystem services (ES are considered the conditions and processes through which natural ecosystems sustain and fulfil human life. In the decision making process related to the natural resources management, two key-aspects must be taken into account: the economic value of the benefits provided by ES (provisioning, regulating and cultural services and the spatial distribution of these benefits. The purpose of the paper is to develop a method aimed to capture the economic value of the benefits provided by ES, in order to support the decision makers in the natural resources management. ES are not homogeneous across landscapes nor in space. Consequently, gaining knowledge on the spatial distribution of the economic relevance of ES is a fundamental information to target management actions. This method was tested in a case study in the Austrian Alps (Leiblachtal area in Vorarlberg region, characterized by a high importance of forests and grasslands. The results show that the highest economic values could be achieved for the provisioning services with a range between 200 €/ha year and 1,400€/ha year. The regulating services have also important economic values, but strongly localized in specific areas (i.e. protective forests against natural hazards. The economic values of the cultural services are influenced by the preferences of tourists and varies between 5 €/ha year to 60 €/ha year. The method allowed us to reveal the spatial heterogeneity of provisioning, regulating and cultural ES, depending on the ecological characteristics of the site.

  6. Modelling technical snow production for skiing areas in the Austrian Alps with the physically based snow model AMUNDSEN

    Tourism and particularly winter tourism is a key factor for the Austrian economy. Judging from currently available climate simulations, the Austrian Alps show a particularly high vulnerability to climatic changes. To reduce the exposure of ski areas towards changes in natural snow conditions as well as to generally enhance snow conditions at skiing sites, technical snowmaking is widely utilized across Austrian ski areas. While such measures result in better snow conditions at the skiing sites and are important for the local skiing industry, its economic efficiency has also to be taken into account. The current work emerges from the project CC-Snow II, where improved future climate scenario simulations are used to determine future natural and artificial snow conditions and their effects on tourism and economy in the Austrian Alps. In a first step, a simple technical snowmaking approach is incorporated into the process based snow model AMUNDSEN, which operates at a spatial resolution of 10-50 m and a temporal resolution of 1-3 hours. Locations of skiing slopes within a ski area in Styria, Austria, were digitized and imported into the model environment. During a predefined time frame in the beginning of the ski season, the model produces a maximum possible amount of technical snow and distributes the associated snow on the slopes, whereas afterwards, until to the end of the ski season, the model tries to maintain a certain snow depth threshold value on the slopes. Due to only few required input parameters, this approach is easily transferable to other ski areas. In our poster contribution, we present first results of this snowmaking approach and give an overview of the data and methodology applied. In a further step in CC-Snow, this simple bulk approach will be extended to consider actual snow cannon locations and technical specifications, which will allow a more detailed description of technical snow production as well as cannon-based recordings of water and energy

    Reconstructing the surface elevation, surface uplift, and relief evolution histories is fundamental to understanding the growth of mountain ranges, to explore their topographic limits, and relate these to geodynamic and Earth surface processes. Recent geologic and geodynamic models for the Central European Alps propose that the bulk of topography was built through the Pliocene, mainly based on the observation of a strong increase in sedimentation and erosion rates during the last 5-6 Ma, suggesting that the Alps never attained elevations as high as today. Here, we aim to quantify the Miocene (20-14 Ma) paleoelevation of the Central Alps through stable isotope paleoaltimetry. The novelty of the approach presented here, which renders it rather insensitive to past climate change, is to analyze stable isotope proxies of identical age, both from high internal parts of the Alpine orogen and from the adjacent foreland basin that was at or near sea level. We first exploit the hydrogen isotopic ratio in phyllosilicates (mica and chlorite) that interacted with meteoric water during activity of the Simplon detachment, a major normal fault that developed during orogen-parallel extension in high elevation regions. We then contrast the resulting meteoric water compositions with those recorded in carbonate-bearing paleosols of the North-Alpine foreland basin to provide an estimate of relative elevation differences. In the North-Alpine foreland basin, we present oxygen and carbon isotopic compositions of pedogenic mudstones and carbonate concretions. These terrestrial paleosols, dated with ca. 100 ka precision, serve as our point of reference for stable isotope paleoaltimetry, since they formed at or near sea level. Here, δ18O and δ13C values vary between +19 to +25% (SMOW) and -7 to +1% respectively and show close correspondence to global climate change during the mid-Miocene climatic optimum. In the Simplon fault zone, detachment-related muscovite (-126%) and chlorite (-135

    Tectonically isolated blocks of carbonate rocks present within the anhydritic Haselgebirge melange of the Northern Calcareous Alps record a complex history of deformation and associated deep-burial diagenetic to very low-grade metamorphic reactions. Fluids were hot (up to ~ 250 ??C) and reducing brines charged with carbon dioxide. Individual carbonate outcrops within the melange record different regimes of brine-rock reactions, ranging from pervasive dolomite recrystallization to dedolomitization. Early diagenetic features in these carbonates were almost entirely obliterated. Matrix dolomite alteration was related to thermochemical sulphate reduction (TSR) recognized by the replacement of anhydrite by calcite + pyrite ?? native sulphur. Pyrite associated with TSR is coarsely crystalline and characterized by a small sulphur isotope fractionation relative to the precursor Permian anhydrite. Carbonates associated with TSR show low Fe/Mn ratios reflecting rapid reaction of ferrous iron during sulphide precipitation. As a result, TSR-related dolomite and calcite typically show bright Mn(II)-activated cathodoluminescence in contrast to the dull cathodoluminescence of many (ferroan) carbonate cements in other deep-burial settings. In addition to carbonates and sulphides, silicates formed closely related to TSR, including quartz, K-feldspar, albite and K-mica. 40Ar/39Ar analysis of authigenic K-feldspar yielded mostly disturbed step-heating spectra which suggest variable cooling through the argon retention interval for microcline during the Late Jurassic. This timing coincides with the recently recognized subduction and closure of the Meliata-Hallstatt ocean to the south of the Northern Calcareous Alps and strongly suggests that the observed deep-burial fluid-rock reactions were related to Jurassic deformation and melange formation of these Permian evaporites.

    Full Text Available Research on chydorid (Crustacea: Cladocera: Chydoridae reproduction is scarce and very little is known about the dynamics of parthenogenetic (asexual and gamogenetic (sexual reproduction modes in these cyclical parthenogens. The paleolimnological approach has a lot to offer to this research since chydorid carapaces (indicative of asexual reproduction and ephippia (indicative of sexual reproduction are identifiable in lake sediments. In the current study, we examined historical changes in chydorid reproduction patterns in an Austrian Alpine lake with the objective to explore reproductive shifts under limnological variability and with the hypothesis that sexual reproduction intensifies under unfavourable environmental conditions. For this, we utilised subfossil remains from a sediment sequence covering the past ~300 years in a high Alpine lake, lake Oberer Landschitzsee. The results suggested that in-lake processes likely changed as a response to post-Little Ice Age (LIA climate warming. Indeed, the benthic quality – indicated by the chironomidbased benthic quality index (BQI – deteriorated, and the productivity – indicated by organic matter in the sediment – increased. The chydorid community exhibited dramatic shifts in the post-LIA section of the core, around 1850-1950 AD, when the two dominant species Alona (A. affinis and A. quadrangularis were outcompeted by Acroperus harpae, Alonella excisa, and Chydorus (C. sphaericus-type and their reproduction gradually shifted towards the dominance of sexual reproduction. The community shift and prevalence of sexual reproduction coincided with the period of unfavourable limnological conditions, evidenced by low BQI values and higher organic content. Therefore, we suggest that the intensified sexual reproduction was a local response to deteriorated benthic conditions and a vigorous adaptive mechanism to ensure successful diapause and genetic variability under environmental change. The results give

    A long-term record of inorganic ion concentrations in wet and dry deposition sampled from snow packs at two high altitude glaciers was used to assess impacts of air pollution on remote sites in central Europe. Sampling points were located at Wurtenkees and Goldbergkees near the Sonnblick Observatory (3106 m above sea level), a background site for measuring the status of the atmosphere in Austria's Eastern Alps. Sampling was carried out every spring at the end of the winter accumulation period in the years 1983-2014. Concentrations of major ions (NH4+, SO42-, NO3-, Ca2+, Mg2+, K+, Na+ and Cl-) were determined using ion chromatography (IC) as well as atomic absorption spectroscopy (AAS) in the earlier years. Concentration of H+ was calculated via the measured pH of the samples. Trends in deposition and concentration were analysed for all major ions within the period from 1983 to 2014 using Kendall's tau rank correlation coefficient. From 1983 to 2014, total ion concentration declined ∼25%, i.e. solutions became ∼25% more dilute, indicating reduced acidic atmospheric deposition, even at high altitude in winter snow. SO42- and NO3- concentrations decreased significantly by 70% and 30%, respectively, accompanied by a 54% decrease of H+ concentrations. Ionic concentrations in snowpack were dominated by H+ and SO42- in the earliest decade measured, whereas they were dominated by Ca2+ by the most recent decade. SO42- and H+ depositions, i.e. concentrations multiplied by volume, also showed a significant decrease of more than 50% at both sites. This reflects the successful emission reductions of the precursor gases SO2 and NOx. Seasonal values with significantly elevated spring concentrations of NH4+, SO42- and H+ compared to fall snow reflects the beginning of vertical mixing during spring. All other ions do not show any seasonality. Source identification of the ions was performed using a principal component analysis (PCA). One anthropogenic cluster (SO42-, NO3- and NH

    In the Alpine environment, one of the main limiting factors for tree growth is the thermal conditions of the vegetative season. The conifers at high altitude, if not subject to others disturbs, such as geomorphological processes or biological interferences, undergo a development, from which the width of annual rings depends. Five chronologies few centuries long, obtained for the species Larix decidua Mill. and Pinus cembra L. from different valleys of the Central Italian Alps (Alpisella, Valfurva, Gavia and Solda) in proximity of timberline (2000-2550 m of altitude), were analysed and their climatic signal gained; this last one was then related to the recent glacial fluctuations. The chronologies are the averages of many dendrochronological indicized curves obtained from dominant trees with regular growth and extended from 13th-17th century up to the present. The time intervals of the chronologies are the following ones: Pinus cembra: 1752-1999 for Valfurva; 1607-1999 for Gavia; 1593-1999 for Val Solda. With regard to Larix decidua: 1252-1998 for Val Solda; 1784-2001 for Alpisella. The good correspondence between the various chronologies allows to consider them representative of the climatic regional signal. In order to evidence climatic evolution, linear trends based on running mean with period of 11 years have been constructed. Those curves have been compared between them and then overlapped and mediated in order to obtain a climatic signal of regional value that excludes eventual local anomalies. Finally, the growth variations in the chronologies have been compared to known alpine climatic variations and glacial fluctuations. In particular time-distance curves (curves of cumulated frontal variations) of some glaciers from the Ortles-Cevedale Group were utilized. The periods of tree rings growth rate reduction appear well correlated to glacial advancing phases of the Little Ice Age and of the following phases. In particular, growth rate reductions are observable

    A detailed geomorphological map of the Gradenbach catchment (32 km², Schober Mountains, Austrian Alps) is presented that focuses on the sediment transfer system. Data were acquired in the field and by the interpretation of orthophotos, LIDAR data and derivatives (slope, curvature, aspect, shaded relief). The resulting digital geomorphological map contains polygon representations of landforms together with their morphometric parameters and an assessment of recent geomorphic activity. Special attention was paid to landform coupling, i.e. an additional table was constructed that indicates recently observable coupling between specific landforms (based on their ID in the database). From these data, we can obtain sediment cascades as a succession of coupled landforms along which sediment transfer occurs through the activity of various geomorphic processes. Based on this digital landform inventory the sediment transfer system is analysed using graph theory. As a rather new approach in geomorphology (already established within several disciplines; e.g. hydrology, biogeography), graph theory provides a promising framework for connectivity analysis in geomorphologic systems and powerful tools to visualise and analyse catchment-wide sediment transfer networks. Since the concept is arbitrarily scalable it can be applied to discrete land surface units (e.g. mapped landforms) or to continuous surface data (e.g. grid cells). In combination with geomorphological mapping, the concept allows for the (abstracted) visualisation of complex coupling relationships between multiple sediment storage landforms. Graph networks can be analysed at the level of nodes (e.g. the number of incoming and/or outgoing edges and their character as sediment source, sink or link), edges (e.g. importance within the network as conveyors of sediment from different sources), pathways (e.g. edge sequences leading to the catchment outlet or to storage landforms; these can be termed sediment cascades), or the

    This review considers potential effects of atmospheric change and climate warming within the timberline ecotone of the Central European Alps. After focusing on the impacts of ozone (O(3)) and rising atmospheric CO(2) concentration, effects of climate warming on the carbon and water balance of timberline trees and forests will be outlined towards conclusions about changes in tree growth and treeline dynamics.Presently, ambient ground-level O(3) concentrations do not exert crucial stress on adult conifers at the timberline of the Central European Alps. In response to elevated atmospheric CO(2)Larix decidua showed growth increase, whereas no such response was found in Pinus uncinata. Overall climate warming appears as the factor responsible for the observed growth stimulation of timberline trees.Increased seedling re-establishment in the Central European Alps however, resulted from invasion into potential habitats rather than upward migration due to climate change, although seedlings will only reach tree size upon successful coupling with the atmosphere and thus loosing the beneficial microclimate of low stature vegetation.In conclusion, future climate extremes are more likely than the gradual temperature increase to control treeline dynamics in the Central European Alps.

  18. Vegetation changes and timberline fluctuations in the Central Alps as indicators of holocene climatic oscillations

    1997-11-01

    Pollen and plant-macrofossil data are presented for two lakes near the timberline in the Italian (Lago Basso, 2250 m) and Swiss Central Alps (Gouille Rion, 2343 m). The reforestation at both sites started at 9700-9500 BP with Pinus cembra, Larix decidua, and Betula. The timberline reached its highest elevation between 8700 and 5000 BP and retreated after 5000 BP, due to a mid-Holocene climatic change and increasing human impact since about 3500 BP (Bronze Age). The expansion of Picea abies at Lago Basso between ca. 7500 and 6200 BP was probably favored by cold phases accompanied by increased oceanicity, whereas in the area of Gouille Rion, where spruce expanded rather late (between 4500 and 3500 BP), human influence equality might have been important. The mass expansion of Alnus viridis between ca. 5000 and 3500 BP probably can be related to both climatic change and human activity at timberline. During the early and middle Holocene a series of timberline fluctuations is recorded as declines in pollen and macrofossil concentrations of the major tree species, and as increases in nonarboreal pollen in the pollen percentage diagram of Gouille Rion. Most of the periods of low timberline can be correlated by radiocarbon dating the climatic changes in the Alps as indicated by glacier advances in combination with palynological records, solifluction, and dendroclimatical data. Lago Basso and Gouille Rion are the only sites in the Alps showing complete palaeobotanical records of cold phases between 10,000 and 2000 BP with very good time control. The altitudinal range of the Holocene treeline fluctuations caused by climate most likely was not more than 100 to 150 m. A possible correlation of a cold period at ca. 7500-6500 BP (Misox oscillation) in the Alps is made with paleoecological data from North American and Scandinavia and a climate signal in the GRIP ice core from central Greenland 8200 yr ago (ca. 7400 yr uncal. BP).

    We present a regional inventory of rock glaciers (n = 1514) and protalus ramparts (228) for the Lombardy region, central Italian Alps. To identify and classify the landforms we inspect three sequential air-orthophoto mosaics and a 2 m-DSM, and conduct confirmatory field work. The inventory forms an empirical basis to analyze: (i) the relative contribution of hillslope (i.e., talus slopes) and glacial (i.e., moraines) sediment stores to rock glacier sediment supply; (ii) linkages between the landforms inventoried and local topographic attributes; (iii) the spatial variability of periglacial activity in relation to a parsimonious set of environmental variables (i.e., elevation, precipitation, and lithology); and (iv) the effects of the Pleistocene-Holocene climatic transition on the distribution of intact and relict landforms. This analysis reveals that the elevation of rock glacier termini can vary over 200 m as a function of slope aspect. In turn, the distribution of rock glaciers among aspect categories is controlled by the structure of the valley network that promotes NW and SE exposures. Talus rock glaciers prevail numerically over the glacier-related typology, even though the latter population appears to have increased during the Holocene. Relict and intact rock glaciers have distinct spatial patterns in that the former display, on average, a 400-m elevation drop and a less clustered distribution towards northern aspects, suggesting that they have developed in more "permafrost-prone" climatic conditions. Analyzing the study region through a 27.5 km-grid has been instrumental for showing that the rock glacier specific area and terminus elevation are: (i) positively correlated with terrain elevation; and (ii) negatively correlated with mean annual precipitation. As a consequence, in relation to Holocene generalized atmospheric temperature rise, intact rock glaciers have progressively disappeared from the wetter and milder portions of the central Italian Alps

  1. Acidification and recovery at mountain lakes in Central Alps assessed by the MAGIC model

    Full Text Available The dynamic model MAGIC was calibrated and applied to 84 lakes in Central Alps to predict the response of water chemistry to different scenarios of atmospheric deposition of S and N compounds. Selected lakes were representative of a wide range of chemical characteristics and of sensitivity to acidification. The most sensitive lakes have already shown in the latest years signs of recovery in terms of pH and ANC. The model well captured the main trends in lake chemical data. According to the model forecast, recovery at sensitive lakes will continue in the next decades under the hypothesis of a further decrease of acidic input from the atmosphere. Results clearly demonstrated the benefits of achieving the emission reductions in both S and N compounds agreed under the Gothenburg Protocol. Nevertheless, besides the achieved reduction of SO4 2- deposition from the peak levels of the 80s, also N deposition should be reduced in the near future to protect alpine lakes from further acidification. The condition of lake catchments with regard to N saturation will probably be the dominant factor driving recovery extent. Beside atmospheric deposition, other factors proved to be important in determining long-term changes in surface water chemistry. Climate warming in particular affects weathering processes in lake catchments and dynamics of the N cycle. Including other factors specific to the alpine area, such as dust deposition and climate change, may improve the fit of experimental data by the model and the reliability of model forecast.

    Full Text Available Abstract Background Dispersal rates, i.e. the effective number of dispersing individuals per unit time, are the product of dispersal capacity, i.e. a species physiological potential for dispersal, dispersal behaviour, i.e. the decision to leave a habitat patch in favour of another, and connectivity of occupied habitat. Thus, dispersal of species that are highly specialised to a certain habitat is limited by habitat availability. Species inhabiting very stable environments may also adopt a sedentary life-style. Both factors should lead to strong genetic differentiation in highly specialised species inhabiting stable environments. These two factors apply to our model species Rhyacophila pubescens a highly specialised freshwater insect that occurs in tufa springs, a very stable habitat. Results We examined the genetic population structure and phylogeography using range-wide mtCOI sequence and AFLP data from 333 individuals of R. pubescens. We inferred the location of Pleistocene refugia and postglacial colonisation routes of R. pubescens, and examined ongoing local differentiation. Our results indicate intraregional differentiation with a high number of locally endemic haplotypes, that we attributed to habitat specificity and low dispersal rates of R. pubescens. We observed high levels of genetic diversity south of the Alps and genetic impoverishment north of the Alps. Estimates of migrants placed the refugium and the source of the colonisation in the Dauphiné Alps (SW Alps. Conclusions This is the first example of an aquatic insect with a colonisation route along the western margin of the Alps to the Central European highlands. The study also shows that specialisation to a stable environment may have promoted a behavioural shift to decreased dispersal rates, leading to stronger local population differentiation than in less specialised aquatic insects. Alternatively, the occurrence of highly specialised tufa spring habitats may have been more

    The longitudinal profile of rivers intersecting the Rhone Valley in the central Swiss Alps suggests the development of topography throughout much of this region has been dominated by interglacial fluvial incision and ongoing tectonic uplift with only minimal glacial erosion since the mid-Pleistocene transition. Evidence indicates bedrock river incision during this period reflects a base level fall of between 500 m and 800 m (depending on the degree of overdeepening following an early period of enhanced glacial incision). This observation raises important questions regarding the preservation, or development of hillslope morphologies through multiple glacial-interglacial cycles. Since the pioneering works of Richter (1900) and Penck and Brückner (1909), Alpine geomorphologists have commented on a sequence of between three and five moderately dipping matched terraces that converge toward inferred paleo-river channels up to 800 m above the axis of many valleys. Here, we use a combination of integral analysis, forward streampower models, and a new method of topographic analysis based on high resolution LiDAR DEMs in order to test the correspondence of valley morphologies in this formerly glaciated landscape, with hillslope processes initiated by fluvial incision up to 700,000 years ago. Results indicate topography adjacent to reaches subjected to transient fluvial incision is characterized by a coherent region of consistently steep slopes, while narrow gorges correspond to rapid incision close to the Rhone valley since MIS 5. A majority of hillslopes converge to our initial fluvial valley floor, or the location of propagating knickpoints. The correspondence between intermediate-level terraces and modeled stages of river incision is, however, currently unclear. These results offer a unique insight into the long-term response of bedrock slopes to varying rates of base level fall, and the cumulative impact of glacial erosion on Alpine valley walls since MIS 11.

    Only few studies have been performed, where the physical interactions between a retreating valley glacier and rock slope movements have been recorded and analyzed in detail. The Driest landslide, situated at the current tongue of the Great Aletsch Glacier in the Swiss Alps, offers a unique case study, because the history of the Great Aletsch Glacier has been studied in great detail by various researchers and the Driest landslide displacements can be unraveled for similar time windows. In this paper we focus on the most recent observation period, i.e. the rockslide and glacier history since the Little Ice Age, when the entire Driest landslide was covered by the glacial ice. Our kinematic model of the Driest landslide, based on field mapping and photogrammetric analyses, was confirmed by displacement vector data from two robotic total stations recording daily displacements of 12 reflectors positioned within the instability. The rockslide basal rupture plane is a compound sliding surface composed of a steeply dipping head scarp, a presumably moderately steep central section, and an upward directed daylighting frontal section. This rupture plane geometry is structurally conditioned by a regional fault in the head scarp area and a rotating Alpine foliation in the toe area. The most recent displacement history of this old rotational rockslide has been unraveled by lichenometry (i.e. systematic mapping of greenish Rhizocarpon Geographicum diameters) in the deepest part of the head scarp, calibrated with dendrochronologic data. Depending on the lichen profile position within the head scarp area, different displacement time histories of the Driest landslide can be developed and correlated with glacial ice elevations as recorded by multiple aerial images and historical documents. Whereas displacement rates before 1991 were in the order of 1 cm/year, significantly higher displacement rates ranging between 7 and 13 cm/year are recorded in the head scarp area for the period

  5. Three-dimensional geometry and tectonostratigraphy of the Pennine zone, Central Alps, Switzerland and Northern Italy

    Continental collision during Alpine orogenesis entailed a polyphase deformation history (D 1-D 5) in the Pennine zone of the Central Alps. The regional tectonostratigraphy was basically developed during D 1 and D 2, characterised by isoclinal, typically north-closing recumbent anticlines, separated by pinched-in synclines, on the scale of tens of kilometres. Later deformation phases (D 3 and D 4) warped the stack into wavy to open folds. Exhumation of this zone resulted locally in later vertical shortening and folding of already steep fabrics (D 5). Three-dimensional models of the nappe pile were constructed, based on geostatistical assessment of the regional foliation field and considering the abundant structural field data. These models indicate the existence of five principal tectonostratigraphic levels developed during D 1 and thus equivalent to nappe units s. str.: the Gotthard, the Leventina-Antigorio, the Maggia-Simano (and probably the Monte Leone as well as the Composite Lepontine Series), Lebendun-Soja and Adula-Cima Lunga levels. All these tectonic units formed part of the passive continental margin of Europe prior to the onset of the Alpine orogenesis. Individual isoclinal post-nappe folds reflect relative displacements on the order of 40 km or more. The most prominent D 2 post-nappe structure is the Wandfluhhorn Fold, structurally equivalent to the northern closure of the Leventina-Lucomagno Antiform. The Lebendun and Monte Leone folds are of similar magnitudes and also affect the whole nappe pile, whereas the smaller Mogno and Molare synforms only refold the Maggia-Simano nappe internally. Principal D 3 and D 4 structures are the tight Mergoscia Synform directly north of the Insubric Fault between Bellinzona and Locarno (Southern Steep Belt), the Maggia Steep Zone, forming the steep western limb of the Campo Tencia Synform and subdividing the Lepontine dome into the Simplon and Ticino subdomes, the Chiéra Synform steepening the dominant foliation in

  6. Chrysotile asbestos quantification in serpentinite quarries: a case study in Valmalenco, central Alps, northern Italy

    Outcrops of serpentinites are usually strongly fractured and cataclastic, and the rock can only be used as ballast. However, in rare cases, like in Valmalenco (Central Alps, Northern Italy), fractures are regular and well spaced, and the rock mass has good geotechnical quality, ideal conditions for the extraction of dimension stone blocks. The Valmalenco Serpentinite is marketed worldwide as dimension and decorative stone, with remarkable mechanical properties and pleasing colours and textures. However, the same area was once subject to chrysotile asbestos mining, in the form of discrete veins along the main discontinuities of the rock mass. For this reason, airborne asbestos contamination can occur during the extraction and processing cycle of the rocks, therefore it is essential to locate and quantify asbestos in the rock mass, to reduce as much as possible the exposure risk. The first step was a detailed geostructural survey of each quarry, in order to characterize the main discontinuities (orientation, spacing, linear persistence, opening, filling), with special attention to the identification of fibrous minerals. The surveys was followed by extensive sampling of massive rocks, mineralized veins and fillings of fractures, and the cutting sludge derived from diamond wire cutting. Preliminary qualitative XRPD was performed on all samples, while quantitative analysis was carried out on the most representative samples of the main rock mass discontinuities. On the other hand, XRPD is not effective in the identification of asbestos percentages of less than 2% by weight, and the accurate distinction among the various serpentine polymorphs (antigorite, lizardite, chrysotile) is very difficult (if not impossible) when they are simultaneously present, due to their very similar basic structure and the strong structural disorder. The same samples were then analyzed by SEM-EDS (fiber counting after filtration on a polycarbonate filter), for a better distinction between

  7. The "green stones" of Valtellina and Valchiavenna (central Alps, northern Italy)

    2015-04-01

    Valtellina and Val Chiavenna (Sondrio, Central Alps, northern Italy) are traditionally areas of production of building and ornamental stones (e.g. Serizzo Ghiandone, Serizzo Valmasino, San Fedelino Granite), and among these the "green stones" have a leading position. These stones had an extensive use in Lombardy, as well as abroad (e.g Switzerland). The "green stones" are related to the two mafic-ultramafic bodies of Valmalenco and Chiavenna, where the two largest quarrying districts of the Province of Sondrio are located. Until the early decades of the XX century, serpentinites (and other lithologies from Valtellina) were also extracted from the erratic boulders of Brianza (north of Milan), but at present time the law protects the few remaining boulders. The extracted and processed materials are various: serpentinites, ophicalcites, soapstones. Even the "Stone of Tresivio", used in the past in important monuments of Valtellina, could be classified among the "green stones" in a broad sense: it is a green chloritic schist with scarce and thin ferriferous calcitic veins, pertaining to the sedimentary "Servino" Formation. In recent times, the ancient quarries of this stone were rediscovered near the homonymous village, a few kilometers from Sondrio. There are also historic reports about other "green stones", used in ancient times, such as the "Stone of Grosio", a chloritic schist, and the "Bormio Prasinite". Currently the extraction and processing of "green stones" occurs mostly in Valmalenco, with 22 active serpentinite quarries and a gross volume of 70000 m3 extracted per year, with a yield of about 50%. The Malenco serpentinite (interpreted as sub-continental mantle rocks) forms a 1-2 km thick tabular body, outcropping over an area of about 170 km2, almost entirely confined within the boundaries of the valley. The antigoritic serpentinites (with variable amounts of olivine, clinopyroxene, chlorite and magnetite) are moderately up to strongly foliated, sometimes

    The Lombardy Alps, with a surface of 2148 km2 above 2000 m a.s.l. (9% of the total) represents an important portion of the southern side of the orogen. For encompassing a variety of tectonic and climatic regimes, they represent an interesting area to examine environmental controls on periglacial processes. Today, technological developments in remote sensing techniques allow us to study periglacial landforms with increasing detail. We present a new inventory for the whole Lombardy Alps in which we identify and classify rock glaciers and protalus ramparts. The inventory has been conducted by combining a number of remotely-sensed images with field traverses. Specifically, the interpretation of high-resolution (0.5 x 0.5 m) digital aerial photos (2000, 2003, 2007) and a 2 m*2 m Digital Surface Model that cover the whole region has allowed inventorying a greater number of relevant landforms when compared to prior regional efforts. Measurements and photographs taken during fieldwork provided critical ground control for the validation of data extracted from remotely-based analysis. Rock glaciers have been mapped in GIS polygons. The inventory follows the specifics detailed by Scapozza and Mari (2010), with some additional information adapted from the PermaNET evidences guidelines (Cremonese et al., 2011). Landform attributes include, geographic coordinates, mountain sector, type, activity, area, elevation (min, max and mean), slope gradient, slope aspect, dominant lithology, vegetation at the front, and upstream presence/absence of a glacier. In total, we identify 1734 periglacial landforms covering a surface of 81,5 km2 (0,34% of the region). In terms of activity, the inventory includes 673 (39%) intact classified and 1061 (61%) relict landforms. The most common landform typology is the talus-lobate (931, 54%) followed by talus tongue-shaped (436, 25%) and protalus ramparts (232, 13%).

    Endolithic microorganisms colonize the pores in exposed dolomite rocks in the Piora Valley in the Swiss Alps. They appear as distinct grayish-green bands about 1-8 mm below the rock surface. Based on environmental small subunit ribosomal RNA gene sequences, a diverse community driven by photosynthesis has been found. Cyanobacteria (57 clones), especially the genus Leptolyngbya, form the functional basis for an endolithic community which contains a wide spectrum of so far not characterized species of chemotrophic Bacteria (64 clones) with mainly Actinobacteria, Alpha-Proteobacteria, Bacteroidetes, and Acidobacteria, as well as a cluster within the Chloroflexaceae. Furthermore, a cluster within the Crenarchaeotes (40 clones) has been detected. Although the eukaryotic diversity was outside the scope of the study, an amoeba (39 clones), and several green algae (51 clones) have been observed. We conclude that the bacterial diversity in this endolithic habitat, especially of chemotrophic, nonpigmented organisms, is considerable and that Archaea are present as well.

    Thermal springs are widespread in the European Alps, where more than 80 geothermal sites are known and exploited. The quantitative assessment of those thermal flow systems is a challenging issue and requires accurate conceptual model and a thorough understanding of thermo-hydraulic properties of the aquifers. Accordingly in the last years, several qualitative studies were carried out to understand the heat and fluid transport processes driving deep fluids from the reservoir to the springs. Our work focused on thermal circulation and fluid outflows of the area around Bormio (Central Italian Alps), where nine geothermal springs discharge from dolomite bodies located close to a regional alpine thrust, called the Zebrù Line. At this site, water is heated in deep circulation systems and vigorously upwells at temperature of about 40°C. The aim of this paper is to explore the mechanisms of heat and fluid transport in the Bormio area by carrying out refined steady and transient three-dimensional finite element simulations of thermally-driven flow and to quantitatively assess the source area of the thermal waters. The full regional model (ca. 700 km2) is discretized with a highly refined triangular finite element planar grid obtained with Midas GTS NX software. The structural 3D features of the regional Zebrù thrust are built by interpolating series of geological cross sections using Fracman. A script was developed to convert and implement the thrust grid into FEFLOW mesh that comprises ca. 4 million elements. The numerical results support the observed discharge rates and temperature field within the simulated domain. Flow and temperature patterns suggest that thermal groundwater flows through a deep system crossing both sedimentary and metamorphic lithotypes, and a fracture network associated to the thrust system. Besides providing a numerical framework to simulate complex fractured systems, this example gives insights into the influence of deep alpine structures on

    Full Text Available The aim of the study was to analyze environmental impact of cow milk production in an alpine area through a cradle-to-farm-gate Life Cycle Assessment and to identify farming strategies that can improve environmental sustainability without negatively affecting profitability. Data were collected from farmers in 28 dairy farms in an Italian alpine valley. The production of 1 kg of fat protein corrected milk (FPCM needed 3.18 m2 of land; land use on-farm was high because a large part of farm land consisted of pastures in the highland, used extensively during summer. Also the use of energy from non-renewable sources was high, 5.14 MJ kg FPCM-1 on average. Diesel for production and transportation of feed purchased off-farm was mainly used, especially concentrates which were entirely purchased. The average emission of greenhouse and acidification causing gases was 1.14 kg CO2-eq and 0.021 kg SO2-eq kg FPCM-1. Eutrophication was on average 0.077 kg of nitrate-eq kg FPCM-1. Farms with low producing cows had higher environmental impact per kg of milk and lower gross margin per cow compared to the others. Low stocking rate farms had the best results regarding acidification and eutrophication per kg FPCM. Farms with high feed self-sufficiency had significantly lower acidification potential than the others. Increasing milk yield per cow, by selection and feeding, and enhancing feed self-sufficiency, by higher forage production and quality and more exploitation of highland pastures, seem to be the best strategies to improve ecological performances of dairy farms in the Alps while maintaining their profitability.

    Scanning electron microscopy revealed great morphological diversity in biofilms from several largely unexplored subterranean thermal Alpine springs, which contain radium 226 and radon 222. A culture-independent molecular analysis of microbial communities on rocks and in the water of one spring, the "Franz-Josef-Quelle" in Bad Gastein, Austria, was performed. Four hundred fifteen clones were analyzed. One hundred thirty-two sequences were affiliated with 14 bacterial operational taxonomic units (OTUs) and 283 with four archaeal OTUs. Rarefaction analysis indicated a high diversity of bacterial sequences, while archaeal sequences were less diverse. The majority of the cloned archaeal 16S rRNA gene sequences belonged to the soil-freshwater-subsurface (1.1b) crenarchaeotic group; other representatives belonged to the freshwater-wastewater-soil (1.3b) group, except one clone, which was related to a group of uncultivated Euryarchaeota. These findings support recent reports that Crenarchaeota are not restricted to high-temperature environments. Most of the bacterial sequences were related to the Proteobacteria (alpha, beta, gamma, and delta), Bacteroidetes, and Planctomycetes. One OTU was allied with Nitrospina sp. (delta-Proteobacteria) and three others grouped with Nitrospira. Statistical analyses suggested high diversity based on 16S rRNA gene analyses; the rarefaction plot of archaeal clones showed a plateau. Since Crenarchaeota have been implicated recently in the nitrogen cycle, the spring environment was probed for the presence of the ammonia monooxygenase subunit A (amoA) gene. Sequences were obtained which were related to crenarchaeotic amoA genes from marine and soil habitats. The data suggested that nitrification processes are occurring in the subterranean environment and that ammonia may possibly be an energy source for the resident communities.

    Full Text Available The Soil and Water Assessment Tool (SWAT was used to simulate five glacierized river basins that are global in coverage and vary in climate. The river basins included the Narayani (Nepal, Vakhsh (Central Asia, Rhone (Switzerland, Mendoza (Central Andes, Argentina, and Central Dry Andes (Chile, with a total area of 85,000 km2. A modified SWAT snow algorithm was applied in order to consider spatial variation of associated snowmelt/accumulation by elevation band across each subbasin. In previous studies, melt rates varied as a function of elevation because of an air temperature gradient while the snow parameters were constant throughout the entire basin. A major improvement of the new snow algorithm is the separation of the glaciers from seasonal snow based on their characteristics. Two SWAT snow algorithms were evaluated in simulation of monthly runoff from the glaciered watersheds: (1 the snow parameters are lumped (constant throughout the entire basin and (2 the snow parameters are spatially variable based on elevation bands of a subbasin (modified snow algorithm. Applying the distributed SWAT snow algorithm improved the model performance in simulation of monthly runoff with snow-glacial regime, so that mean RSR decreased to 0.49 from 0.55 and NSE increased to 0.75 from 0.69. Improvement of model performance was negligible in simulations of monthly runoff from the basins with a monsoon runoff regime.

    We present new data of the geological map of the Osogna sheet in the Southern Swiss Alps (Swiss National Map no. 1293) that extends N-S from Biasca to Claro and W-E from Lavertezzo to the Pizzo di Claro, respectively. The area mapped at the 1:10'000 scale is located in the Lepontine dome and includes, from core-to-carapace, the gneissic nappes of the Leventina, Simano, Adula/Cima-Lunga and Maggia. These nappes derive from the same post-Variscan gneissic basement complicating their lithological distinction and making difficult to recognize their boundaries. In particular, the boundary between the Leventina and the Simano gneisses is difficult to recognize. In previous work, this boundary was traced within leucogneisses by joining a carbonate lens with quartzite, amphibolite or paragneiss lenses. Nevertheless, quartzites are absent in the mapped area and amphibolite and paragneiss lenses are vertically distributed in the tectonostratigraphy and do not form a single folded horizon. Furthermore, no significant strain gradient related to top-to-the-foreland shearing has been observed between these two units, also when paragneisses and amphibolites were present. Therefore, we present evidence that the top-to-the-foreland deformation between the Leventina and the Simano units was more distributed that commonly assumed, questioning the allochthonous character of the Simano unit.

    Chironomids and pollen were studied in a radiocarbon-dated sediment sequence obtained from a former lake near the Maloja Pass in the Central Swiss Alps (1865 m a.s.l.) to reconstruct the Lateglacial environment. Pollen assemblages imply a vegetation development around the Maloja Pass from shrub tundra at the beginning of the Allerød to coniferous forest during the early Holocene with a lowering of the timberline during the Younger Dryas. Chironomid assemblages are characterized by several abrupt shifts in dominant taxa through the Lateglacial. The occurrence of taxa able to survive hypoxia in the second part of the Allerød and during the Preboreal, and their disappearance at the onset of the Younger Dryas cold phase suggest summer thermal stratification and unfavourable hypolimnetic oxygen conditions in the palaeo-lake during the warmer periods of the Lateglacial interstadial and early Holocene. Mean July air temperatures were reconstructed using a chironomid-temperature transfer function from the Alpine region. The pattern of reconstructed temperature changes agrees well with the Greenland δ18O record and other Lateglacial temperature inferences from Central Europe. The inferred July temperatures of ca 10.0 °C during most of the Allerød were slightly lower than modern values (10.8 °C) and increased up to ca 11.7 °C (i.e., above present-day values) at the end of the Allerød. The first part of the Younger Dryas was colder (ca 8.8 °C) than the second part (ca 9.8 °C). During most of the Preboreal, the temperatures persisted within the limits of 13.5-14.5 °C (i.e., ca 3 °C above present-day values). The amplitudes of temperature changes at the Allerød-Younger Dryas-Preboreal transitions were ca 3.5-4.0 °C. The temperature reconstruction also shows three short-lived cooling events of ca 1.5-2.0 °C, which may be attributed to the centennial-scale Greenland Interstadial events GI-1d and GI-1b, and the Preboreal Oscillation.

    Moraine systems of the "Egesen Stadial" are widespread and easily identifiable features in the Alps. Absolute dating with terrestrial cosmogenic radionuclides shows that the maximum extent was reached during the early Younger Dryas (YD), probably as a reaction to the intense climatic downturn subsequent to Lateglacial Interstadial. In recent years, several new studies and the availability of high-quality laser-scan hillshades and orthophotos allowed a significant extension of the database of YD glaciers as "palaeoprecipitation gauges" to large hitherto unmapped regions in the Austrian and Swiss Alps. The equilibrium line altitude (ELA) of the glaciers and its lowering relative to the Little Ice Age ELA (dELA) shows a distinct and systematic spatial pattern. Along the northern slope of the Alps, dELAs are usually large (around 400 m and perhaps even more), while dELAs range around 200 m in the well sheltered areas of the central Alps, e.g. in the Engadine and in western Tyrol. Both stochastic glacier-climate models (e.g. Ohmura et al. 1992) and the heat- and mass balance equation (Kuhn 1981) allow the reconstruction of precipitation change under the assumption of a spatially constant summer temperature depression, which in turn can be estimated from biological proxies. This allows to draw the spatial pattern of precipitation change with considerable detail. Precipitation change is clearly controlled by the local relief like high mountain chains, deeply incised and long valleys and mountain passes. Generally the contrast between the northern fringe of the Alps and the interior was more pronounced than today. Climate in the Northern and and Northwestern Alps was rather wet with precipitation totals eventually exceeding modern annual sums. The central Alps received 20 - 30% less precipitation than today, mainly due to reduced winter precipitation. In the southern Alps, still scarce spatial information points to precipitation sums which were approximately similar to

  20. Asbestos exposure during quarrying and processing of serpentinites: a case study in Valmalenco, Central Alps, Northern Italy

    Serpentinites are metamorphic rocks derived from ultramafics such as peridotites (lherzolites and/or harzburgites), with a typical mineralogical assemblage of antigorite, olivine, diopside and minor magnetite, chlorite and chrysotile. If the rock mass has good geotechnical properties, these stones are quarried because of their wide variety of green shades and outstanding technical properties. Excellent stones are produced in the Malenco Valley, Central Alps (northern Italy, Sondrio): here the geological set-up is dominated by the ultramafic Malenco massif (lower crust-mantle complex), exposed at the Penninic to Austroalpine boundary zone. Different processing operations give origin to valuable products like stoves, funeral monuments, design home appliances; important building element as roof slabs, tiles for floor and wall coverings constitute the main commercial line of production. In this area, good quality long fibre chrysotile asbestos was mined since the XIX century, till the seventies. The asbestos fissures (mostly slip-fiber) are well known in Valmalenco, associated to an important ENE-WSW striking fracture and hydrothermal vein system. Some actual serpentinite quarries "cross" at times tunnels of the old asbestos mines, because the fracture and vein system "guides" the extraction. At present time, this area represents an excellent example of naturally occurring asbestos (NOA). For these reasons, workers' exposure to asbestos during quarrying and processing cannot be ruled out, and must be assessed according to national laws. From 2004 to nowadays, the INAIL Regional Management of Lombardia, with the collaboration of University of Milan-Bicocca, carried out extensive monitoring campaigns both in quarries and in processing laboratories. More than 300 massive samples (rocks and veins) and 250 airborne dust samples were collected during the surveys. One of the main problems in the study of massive serpentinites is the accurate identification of the different

    The presented studies were carried out in order to check the usefulness of subfossil wood for stable isotope analysis. The aim of research was also to define the optimal method of subfossil samples preparation. Subfossil samples used during the presented studies are a part of the multi-century dendrochronological scale. This chronology originates in an area situated around a small mountain lake — Schwarzersee, in Austria. The obtained results of stable carbon isotope measurements confirmed that the method of α-cellulose extraction by the application of acidic sodium chlorite and sodium hydroxide solutions removes resins and other mobile compounds from wood. Therefore, in the case of the analysed samples, the additional chemical process of extractives removing was found to be unnecessary. Studied wood samples contained an adequate proportion of α-cellulose similar to the values characteristic for the contemporary trees. This proved an adequate wood preservation which is essential for the conduction of isotopic research. PMID:26346297

    Although it is frequently assumed that crust of Alpine orogens is hot due to the occurrence of thick and young (hence radiogenic) crust, evidence on the thermal ranking of orogens is contradictory. Heat flow measurements from shallow wells (depth ≤ 1 km) in the Alps yield a relatively cold thermal regime of 50-80 mW/m2, but data are likely biased by meteoric cold-water circulation. Here we report on the spectral analysis of the aeromagnetic residuals of northern Italy to derive the Curie point depth (CPD), assumed to represent the 600°C isotherm depth. Airborne magnetics were acquired on whole Italy during the 1970s by the national oil company AGIP (now Eni). Data were gathered by several surveys carried out at 1000-13,300 feet (300-4000 m) altitude, with flight line spacing of 2-10 km. Surveys of the Alps and Po Plain (northern Italy) were obtained both with a line spacing of 5 km (and 5 km tie lines), at an altitude of 4000-5000 and 13,300 feet, respectively. To evaluate CPDs we used the centroid method (routinely adopted in recent CPD studies on East Asia and central-southern Europe) on 72 square windows of 100-110 km edge, with a 50% degree of superposition. CPDs vary between 16 and 38 km (22 km on average) in the Po Plain, located south of the Alps and representing the Adriatic-African foreland area. Conversely, the Alps yield very shallow CPDs, ranging between 6 and 15 km (10 km on average). CPDs fall systematically above local Moho depths, implying that magnetic source bottoms documented in this study do not represent a lithological boundary over non-magnetic peridotitic mantle, but can be safely associated with CPDs and the 600°C isotherm. CPDs from the Po Plain are in rough agreement with reported heat flow values of 25-60 mW/m2, and imply and average thermal conductivity (k) of the Po Plain crust of 1.5 W/m°K, at the lower bound of k values measured and inferred for the crust. Conversely, the average 10 km CPD documented in the Alps translates into

  7. Major and trace-element composition and pressure-temperature evolution of rock-buffered fluids in low-grade accretionary-wedge metasediments, Central Alps

    2013-05-01

    The chemical composition of fluid inclusions in quartz crystals from Alpine fissure veins was determined by combination of microthermometry, Raman spectroscopy, and LA-ICPMS analysis. The veins are hosted in carbonate-bearing, organic-rich, low-grade metamorphic metapelites of the Bündnerschiefer of the eastern Central Alps (Switzerland). This strongly deformed tectonic unit is interpreted as a partly subducted accretionary wedge, on the basis of widespread carpholite assemblages that were later overprinted by lower greenschist facies metamorphism. Veins and their host rocks from two locations were studied to compare several indicators for the conditions during metamorphism, including illite crystallinity, graphite thermometry, stability of mineral assemblages, chlorite thermometry, fluid inclusion solute thermometry, and fluid inclusion isochores. Fluid inclusions are aqueous two-phase with 3.7-4.0 wt% equivalent NaCl at Thusis and 1.6-1.7 wt% at Schiers. Reproducible concentrations of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, B, Al, Mn, Cu, Zn, Pb, As, Sb, Cl, Br, and S could be determined for 97 fluid inclusion assemblages. Fluid and mineral geothermometry consistently indicate temperatures of 320 ± 20 °C for the host rocks at Thusis and of 250 ± 30 °C at Schiers. Combining fluid inclusion isochores with independent geothermometers results in pressure estimates of 2.8-3.8 kbar for Thusis, and of 3.3-3.4 kbar for Schiers. Pressure-temperature estimates are confirmed by pseudosection modeling. Fluid compositions and petrological modeling consistently demonstrate that chemical fluid-rock equilibrium was attained during vein formation, indicating that the fluids originated locally by metamorphic dehydration during near-isothermal decompression in a rock-buffered system.

  8. Origin and significance of the Permian high-K calc-alkaline magmatism in the central-eastern Southern Alps, Italy

    The Atesina Volcanic District, the Monte Luco volcanics, and the Cima d'Asta, Bressanone-Chiusa, Ivigna, Monte Croce and Monte Sabion intrusions, in the central-eastern Southern Alps, form a wide calc-alkaline association of Permian age (ca. 280-260 Ma). The magmatism originated during a period of post-orogenic extensional/transtensional faulting which controlled the magma ascent and emplacement. The magmatic products are represented by a continuum spectrum of rock types ranging from basaltic andesites to rhyolites, and from gabbros to monzogranites, with preponderance of the acidic terms. They constitute a metaluminous to weakly peraluminous series showing mineralogical, petrographic and chemical characteristics distinctive of the high-K calc-alkaline suites. In the MORB-normalized trace element diagrams, the most primitive volcanic and plutonic rocks (basaltic andesites and gabbros with Mg No.=66 to 70; Ni=25 to 83 ppm; Cr=248 to 679 ppm) show LILE and LREE enriched patterns with troughs at Nb-Ta and Ti, a distinctive feature of subduction-related magmas. Field, petrographic, geochemical and isotopic evidence (initial 87Sr/ 86Sr ratios from 0.7057 to 0.7114; ɛNd values from -2.7 to -7.4; ∂ 18O values between 7.6 and 9.5‰) support a hybrid nature for both volcanic and plutonic rocks, originating through complex interactions between mantle-derived magmas and crustal materials. Only the scanty andalusite-cordierite and orthopyroxene-cordierite bearing peraluminous granites in the Cima d'Asta and Bressanone-Chiusa intrusive complexes can be interpreted as purely crustal melts (initial 87Sr/ 86Sr=0.7143-0.7167; initial ɛNd values between -7.9 and -9.6, close to average composition of the granulitic metasedimentary crust from the Ivrea Zone in the western Southern Alps). Although the Permian magmatism shows geochemical characteristics similar to those of arc-related suites, palaeogeographic restorations, and geological and tectonic evidence, seem not to support

    Full Text Available In light of the current events, namely the crisisthat economy has to face for quite someyears now, plenty of questions are raised, not only among specialists in the field but also amongordinary people as they prove to be most impoverished by these imbalances. Thus, this paper aims, asa first objective, to explain, froma general perspective and using an inductive-subjectivemethodology based on a brief survey as well as on observation, two of the most important causes that,according to the Austrian Business Cycle Theory, are the leading motives for triggering crises. Weare referring particularly to an excessivestate interventionismmanifested throughout itsexpansionary monetary policy.Secondly, we seek to establish the interconnections between theseelements and the case of the Great Depression as well as the current recession. The results we cameacross point out towards the same pattern designed by the Austrian economists, although thecircumstances are, each time, different. Hence, the contribution of this paper consists of handling thedetails that surround the subject by extracting only the essential aspects regarding the triggering ofcrises; we refer to the main ideas that need to be underlined for a better comprehension of the topic.

  10. Erosion rates, sediment transport and characteristic discharge in a transient landscape in the Entle catchment (northern border of the Central Alps, Switzerland)

    2010-05-01

    The 65 km2-large Entle catchment is located at the northern border of the Central Alps of Switzerland and is underlain by various lithologies including Flysch, carbonate sequences, Molasse deposits and glacial till. It has been subjected to headward knickpoint migration since the termination of the LGM (16 ± 3 ka), due to a base level fall upon glacial retreat. The incised portions of the catchment were delineated within a GIS environment in an effort to calculate volumetric differences between the glacial surface and the modern topography. The sediment budget estimates yield an average erosion rate of 1.93 ± 0.36 mm.yr-1 in the incised reaches, and a maximum local erosion rate of 11.47 ± 2.15 mm.yr-1. Assuming that there has been no erosion elsewhere, the basin-wide averaged erosion rate is estimated at 0.31 ± 0.06 mm.yr-1. This is consistent with 10Be-based denudation rates measured in adjacent catchments. Although constant erosion rates are generally assumed for studies involving 10Be analysis, field evidence indicate that headward knickzone migration through bedrock and unconsolidated glacial till has destabilized the surrounding hillslopes, resulting in supply of large volumes of sediment to the trunk channel by landsliding and/or debris flows downstream the knickzone. This additional influx of sediments may raise the local base level within the incised reach, thus perturbing the migration of the knickzone for a limited time interval. This time span critically depends on the relative importance between the probability density function (PDF) of the sediment particle size supplied by mass failure processes and debris flows, and the characteristic water discharge magnitude to remove that material. Measurements of the PDFs of the sediment particles along the incised Entle reach together with the application a simple long profile stream-power model for the entrainment and transport of sediment allow the identification of characteristic bed-forming discharge

    Previous studies have shown that convection-permitting simulations accurately reproduce the diurnal cycle of precipitation, especially over mountainous regions in summer. However, a strong dependency to elevation has been shown with COSMO-CLM at 3km. Indeed, the model is unable to reproduce the mid-afternoon peak in low- and flat-lands in the Eastern Alps. Associated processes are investigated in the framework of NHCM-2 (project number P24758-N29), using a set of sensitivity experiments over the greater Alpine region. These experiments are designed to cover a broad range of influences, including orographic forcing and physical parametrizations. Model evaluation is performed with a set of observations-based high-quality datasets at 1km over the Eastern Alps. These datasets are provided by the Austrian Central Department for Meteorology and Geodynamics (ZAMG), and include data from the now-casting system INCA, and newly generated gridded dataset from homogenized high-density network of in situ measurement stations. First results of process-oriented analysis will be presented in the context of model inter-comparison with WRF.

    The Austrian UV Monitoring network is operational since 1998 providing a large data set of erythemally weighted UV irradiance recorded with broadband UV biometer at 12 stations distributed all over Austria. In order to obtain high quality data all biometer are recalibrated once a year, the detectors are checked regularly for humidity and quality control is done routinely. The collected data are processed and then published on the website http://www.uv-index.at where the UV-Index of all measurement sites is presented in near real time together with a map of the distribution of the UV-Index over Austria. These UV-Index data together with measurements of global radiation and ozone levels from OMI are used to study long term trends for the stations of the monitoring network. Neither for all weather conditions nor for clear sky conditions is a statistically significant trend found for the UV-Index (with one exception) and for ozone. Furthermore, the radiation amplification factor (RAF) is determined experimentally from the power law correlation between UV-Index and ozone level for the site Innsbruck (577 m above sea level, 47.26°N, 11.38°E) for 19°solar elevation. A value of 0.91 ± 0.05 is found for the RAF for clear sky days with low ground albedo and a value of 1.03 ± 0.08 for days with high ground albedo (snow cover).

  20. The chemical and biological response of two remote mountain lakes in the Southern Central Alps (Italy to twenty years of changing physical and chemical climate

    Directory of Open Access Journals (Sweden)

    Andrea LAMI

    2004-02-01

    Full Text Available Two small high mountain lakes in the Alps were monitored in 1984-2003 to follow their response to changes in human impact, such as deposition of atmospheric pollutants, fish stocking and climate change. The results were compared to occasional samplings performed in the 1940s, and to the remains found in sediment cores. When monitoring started, the most acid-sensitive of them, Lake Paione Superiore, was acidified, with evident effects in its flora and fauna: benthic diatoms assemblage was shifted towards acidophilous species, and zooplankton lost the dominant species, Arctodiaptomus alpinus. Palaeolimnological studies outlined that lake acidification paralleled the increasing input of long-range transported industrial pollutants, traced by spherical carbonaceous particles. On the contrary, the biota of Lake Paione Inferiore appeared to be mainly affected by fish stocking. In the last twenty years, decrease in acid load from the atmosphere led to an improvement in lake water quality, with an increase in both pH and alkalinity. First signs of biological recovery were identified, such as change in diatom flora and appearance of sensitive species among benthic insects. However, climate change and episodic deposition of Saharan dust were important driving factors controlling lake water chemistry. Further monitoring to assess the effects of climate change and of the increasing load of nitrogen and other pollutants is recommended.

    The archive of the Austrian Alpine Club holds masses of material on glaciers and their former extent. The material includes descriptions and sketches of the summits conquered by early mountaineers, mapping campaigns and data from early scientific expeditions as well as data on glacier length change. To date a large proportion of the glaciological information in the material has not been catalogued or analysed. As cold ice, containing relevant climate information, might still exist at the highest peaks of Austria, a pilot project was started to collect some of the data of two test sites in Tyrol, in Silvretta and Ötztal Alps, to reveal former summit shapes and glacier tongue positions. Additional information on the number and position of crevasses as well as firn extent is often evident from the material. Challenging tasks not yet tackled are compiling a catalogue of the material and defining an analysis scheme.

    The alkaloid content of Adenostyles alliariae and A. glabra (Asteraceae) has been evaluated. Both species contain toxic macrocyclic unsaturated pyrrolizidine alkaloids with seneciphylline as the main compound accounting for more than 90% of the alkaloid fraction in all above ground plant parts. Further alkaloids were spartioidine, acetyl-senciphylline and senecionine. Inflorescences showed the highest alkaloid contents with 21.1 and 13.4 mg/g in A. alliariae and A. glabra, respectively. Stems and leaves had 2-3 times lower contents. Therefore, these Adenostyles species must be considered as highly toxic plants.

    We analyze the directed, weighted and evolutionary Austrian airline flight network. It is shown that such a specific airline flight network displays features of small-world networks, namely large clustering coefficient and small average shortest-path length. We study the detailed flight information both in a week and on a whole. In both cases, the degree distributions reveal power law with exponent value of 2 $\\sim$ 3 for the small degree branch and a flat tail for the large degree branch. Similarly, the flight weight distributions have power-law for the small weight branch. The degree-degree correlation analysis shows the network has disassortative behavior, i.e. the large airports are likely to link to smaller airports.

  8. Subglacial bedrock topography of an active mountain glacier in a high Alpine setting - insights from high resolution 3D cosmic-muon radiography of the Eiger glacier (Bern, Central Alps, Switzerland)

    Bedrock topography and therefore the spatial-altitudinal distribution of ice thickness constrain the ice flow as well as the erosional mechanisms of glaciers. Although the processes by which glaciers have shaped modern and past landscapes have been well investigated, little information is still available about the shape of the bedrock beneath active glaciers in steep Alpine cirques. Here, we we apply the cosmic-muon radiography technology, which uses nuclear emulsion detectors for imaging the bedrock surface. This method should provide information on the bedrock topography beneath a glacier and related ice thicknesses and subglacial meltwater pathways. We apply this technology to the cirque of the Eiger glacier, situated on the western flank of Eiger mountain, Central Swiss Alps. The Eiger glacier originates on the western flank of the Eiger at 3700 m a.s.l., from where it stretches along 2.6 km to the current elevation at 2300 m a.s.l.. The glacier consists of a concave cirque bordered by >40° steep flanks, thereby utilizing weaknesses within the fabric of the bedrock such as folds, joints and foliations. The middle reach hosts a bedrock ridge where glacier diffluence occurs. The lower reaches of the glacier are characterized by several transverse crevasses, while the terminal lobe hosts multiple longitudinal crevasses. A basal till and lateral margins border the ice flow along the lowermost reach. While subglacial erosion in the cirque has probably been accomplished by plucking and abrasion where the glacier might be cold-based, sub glacial melt water might have contributed to bedrock sculpting farther downslope where the ice flow is constrained by bedrock. Overdeepening of some tens of meters is expected in the upper reach of the glacier, which is quite common in cirques (Cook & Swift, 2012). Contrariwise, we expect several tens of meters-deep bedrock excavations (characterized by concave curvatures of bedrock surface) at the site of ice diffluence. The next

    Full Text Available Relations between France and the Habsburg Empire during the long nineteenth century went through several phases bounded by the events crucial not just to the two countries' mutual relations but to all of Europe. The Congress of Vienna defined their mutual relations for the next thirty years. The Habsburgs and their omnipresent minister Metternich were fearful of revolutionary and liberal movements traditionally having their origins in France. And it was the revolutionary events of 1848 that brought about a change in the balance of power and their mutual relations. Metternich's retirement and, more importantly, the arrival of the Russian armies in Central Europe and the subsequent strengthening of Prussia, conferred a new importance to the role of the Habsburg Monarchy as a bulwark against the advancement of Russia and a vital counterweight to Prussia. With the defeat of Napoleon III and the creation of Germany with Alsace and Lorraine Franco-Austrian relations entered a new phase. The destiny of the two provinces alienated the Habsburgs from the French Republic, especially after the reorganization of Europe into two confronting blocs. The logic of alliances led to their being adversaries in the world conflict, although Napoleon III's geo-strategic analyses remained present almost to its very end, when Clemenceau's government gave support to the nationality principle thereby crucially contributing to the collapse of the Habsburg Monarchy.

    Physicians dealing with prophylactic measures for tourists going to developing countries will often not be able to foresee the outcome of their recommendations. Therefore an open study with 2,627 Austrian tourists on their flight home from a tropical destination was carried out to evaluate the behaviour of typical short-term travellers with respect to different kinds of precautionary measures. 94.1% of all tourists informed themselves before travelling abroad, but a high proportion of travellers tends to contact only their travel agency or their personal friends, this leading to inadequate information. Regarding the individual performance of precautionary measures the results indicate a few principal conclusions: Among the recommended inoculations the vaccinations against typhoid fever, poliomyelitis and tetanus are widely underestimated, the latter two in particular for adults, while compliance with the passive immunization against Hepatitis A is generally good (more than 80% of all travellers receive Hepatitis A immunoglobulins prophylactically). The most crucial point seems to be the chemoprophylaxis against malaria in as much as a) there seems to be a considerable lack of information about malaria endemic areas among physicians, b) tourists tend to use the most simple applicable drug unaware of epidemiological considerations and c) the regular intake of chemoprophylaxis declines significantly with the complexity of the intake procedure. In addition, tourists are in general well informed about nutritional risks, but only half of them will receive adequate information on the risk of sexually transmitted diseases and a basic medical travel kit.

  13. HORA - an Austrian platform for natural hazards

    HORA - an Austrian platform for natural hazards as a new way in risk communication One initiatives launched in Austria demonstrate that public participation not only bears the risk of a partial transfer of responsibility by the authorities; it may above all prepare the ground for entirely new approaches and create new links. The recent installation of the first internet risk zoning system in Austria underscores the importance of involving private parties in natural disaster protection. This public-private partnership (PPP) between the Federal Ministry of Agriculture, Forestry, Environment and Water Management (BMLFUW) and the Austrian Insurance Association (VVO) was launched in the wake of the 2002 flood disaster. The first project phase, the Austrian flood risk zoning system called HORA (screenshot see fig. 1), has now been accessible on the Web since 1st June 2006. In accordance with a risk partnership concluded between federal government, insurance companies and private parties, the project initiators seek to offer the public a preliminary risk assessment tool for evaluation of their home, industrial enterprise, of infrastructure. Digital risk maps shall provide information on 30-year, 100-year and 200-year flood events as they occur alongside the 26.000-km-long domestic river network. The probability with which a certain block of land is immersed in water during a flood event can be calculated by means of hydraulic engineering methods. These have traditionally relied on statistical figures, which are known to be very inaccurate, especially when major events such as flooding are concerned. The Vienna University of Technology (TU) (Institute of Hydraulic and Water Resources Engineering) has dedicated many years to developing more accurate, process oriented risk assessment techniques. The starting points was to identify different flood-triggering processes and to divide them into specific categories as long-duration rainfalls, short-duration rainfalls, storms

    The victories near Ulm and Elchingen, where the Napoleonic army took 60000 prisoners between 15th and 20th of October 1805, lead to the arrival at Troyes (county "Aube") of nearly 2000 Austrian soldiers to be held inside former monasteries among whose, mainly the Jacobinians casern where more than half of them stayed. At the beginning of 1806, the government sent the epidemics medical practitioner Dr Desgenettes on an inspection tour to control the state of health of the populations of places where foreign prisoners were held, which lead him through several counties of the North-eastern part of France, where he surveyed several diseases ranging from all kinds offevers up to dysentery, scabies or gangrenes. With the means of acid fumigations invented by the chemist Guyton Morveau from Dijon, the authorities took care of combating and preventing the epidemics in the caserns. As soon as October 1805, the epidemics medical practitioner Dr Pigeotte from Troyes wrote to the county governor his observations recommending a better diet, airing of the rooms and also calls to take some exercise. All these precepts showed an astonishing modernity.

  15. Sociotechnical scenarios for the Austrian energy system

    2012-10-01

    Full Text Available Reducing greenhouse gases by 80%, as demanded by the IPCC, is one of the great long-term challenges facing our societies today and will doubtless require transformative changes to current energy regimes. Large-scale system transitions such as the one envisaged for the global energy system in the next 30–40 years can only be realized through complex processes of change involving global, regional, national, and local levels. In this paper we use sociotechnical scenario analysis to contribute ideas for the transformative change of the current Austrian energy system over the long term and to identify some of the particular policy measures, as well as structural changes and broader shifts in perspective, that would be necessary to deal with such challenges. There is less emphasis on the technical issues involved than on the socio-economic and governance requirements such a shift would demand. We also explain our experiences with the sociotechnical scenario process and its outcomes. In particular, we identify examples of some critical issues and opportunities within one of the identified key action fields and discuss their various implications for energy policy and everyday practices.

  16. Austrian Economics and the Transaction Cost Approach to the Firm

    2009-10-01

    Full Text Available As the transaction cost theory of the firm was taking shape in the 1970s, another important movement in economics was emerging: a revival of the ‘Austrian’ tradition in economic theory associated with such economists as Ludwig von Mises and F. A. Hayek (1973; Dolan, 1976; Spadaro, 1978. As Oliver Williamson has pointed out, Austrian economics is among the diverse sources for transaction cost economics. In particular, Williamson frequently cites Hayek (e.g., Williamson, 1985, p. 8; 1991, p. 162, particularly Hayek’s emphasis on adaptation as a key problem of economic organisation (Hayek, 1945. Following Williamson’s lead, a reference to Hayek’s ‘The Use of Knowledge in Society’ (Hayek, 1945 has become almost mandatory in discussions of economic organisation (e.g., Ricketts, 1987, p. 59; Milgrom and Roberts, 1992, p. 56; Douma and Schreuder 1991, p. 9. However, there are many other potential links between Austrian and transaction cost economics that have not been explored closely and exploited.This article argues that characteristically Austrian ideas about property, entrepreneurship, economic calculation, tacit knowledge, and the temporal structure of capital have important implications for theories of economic organisation, transaction cost economics in particular. Austrian economists have not, however, devoted substantial attention to the theory of the firm, preferring to focus on business-cycle theory, welfare economics, political economy, comparative economic systems, and other areas. Until recently the theory of the firm was an almost completely neglected area in Austrian economics, but over the last decade, a small Austrian literature on the firm has emerged. While these works cover a wide variety of theoretical and applied topics, their authors share the view that Austrian insights have something to offer students of firm organisation.

  17. Review: Natural tracers in fractured hard-rock aquifers in the Austrian part of the Eastern Alps—previous approaches and future perspectives for hydrogeology in mountain regions

    Science.gov (United States)

    Hilberg, Sylke

    2016-08-01

    Extensive in-depth research is required for the implementation of natural tracer approaches to hydrogeological investigation to be feasible in mountainous regions. This review considers the application of hydrochemical and biotic parameters in mountain regions over the past few decades with particular reference to the Austrian Alps, as an example for alpine-type mountain belts. A brief introduction to Austria's hydrogeological arrangement is given to show the significance of fractured hard-rock aquifers for hydrogeological science as well as for water supply purposes. A literature search showed that research concerning fractured hard-rock aquifers in Austria is clearly underrepresented to date, especially when taking the abundance of this aquifer type and the significance of this topic into consideration. The application of abiotic natural tracers (hydrochemical and isotope parameters) is discussed generally and by means of examples from the Austrian Alps. The potential of biotic tracers (microbiota and meiofauna) is elucidated. It is shown that the meiofauna approach to investigating fractured aquifers has not yet been applied in the reviewed region, nor worldwide. Two examples of new approaches in mountainous fractured aquifers are introduced: (1) use of CO2 partial pressure and calcite saturation of spring water to reconstruct catchments and flow dynamics (abiotic approach), and, (2) consideration of hard-rock aquifers as habitats to reconstruct aquifer conditions (biotic approach).

  18. Air pollution damage to Austrian pine in New Jersey

    1967-11-01

    Following a period of high pollution, extensive needle damage was observed on Austrian pine trees. Since the species is common in New Jersey, it was possible to obtain an approximation of its sensitivity. In nurseries, Christmas tree plantations and park areas, which included many species of conifers in addition to Austrian pine, species specifically noted as free from apparent damage were white pine (Pinus strobus), scotch pine (P. sylvestris), red pine (P. resinosa), Atlas cedar (Cedrus atlantica glauca), Norway spruce (Picea abies), Colorado spruce (P. pungens), white spruce (P. canadensis), balsam fir (Abies balsamea), Douglas-fir (Pseudotsuga taxifolia), and many varieties of juniper, arbor vitae, hemlock, and yew. During the survey needle damage, which could be traced back to the episode of 24 June, was also observed on Japanese red pine (P. densiflora) and Japanese black pine (P. densiflora) and Japanese black pine (P. Thunbergil). The injury to Japanese red pine was identical to that on Austrian pine, but on Japanese black pine the damage appeared not on the current year's needles, but on 1-year-old needles and it did not have the distinctive dividing line between injured and healthy tissue. These two species did not occur in sufficient number to allow further evaluation. Austrian pine has been cited in the literature as very tolerant of industrial smoke. Currently, German foresters are advising aginst the use of spruce and firs in industrial areas and are recommending ''resistant species as Austrian pine.'' In New Jersey fluoride damage has been observed on Austrian pine on occasion over the past 20 years. Because of the damage also caused by photochemical smog in New Jersey, the resistance of the species should be reevaluated. A need may develop for a breeding program to provide resistant material to the highly polluted metropolitan areas.

  19. The Austrian Business Cycle Theory: Validity and Implications

    In this thesis the Austrian business cycle theory is analyzed. Based on the work of Eugen von Böhm-Bawerk (1959[1889]), Knut Wicksell (1962[1898]) and Ludwig von Mises (1953[1912]), the theory was further developed and made famous by Friedrich von Hayek in the 1930s. Arguably, Hayek was the main rival of Keynes during this decade, but after heavy criticism and the publication of the General Theory (Keynes, 1936), the Austrian business cycle theory was left with few advocates by the end of Wor...

  20. THE HUNGARIAN CRISIS: AN AUSTRIAN SCHOOL EXPLANATION

    2013-07-01

    Full Text Available The Hungarian model was heralded as one of the most successful post-socialist way of integration into the globalised world economy and European economic area in the nineties. Currently, Hungary is suffering from a full-blown crisis 1996 onwards. Increasingly large number of Hungarians is losing their faith in political parties, institutions, democracy and in market economy. The government, elected in 2010 by supermajority and still enjoying a broad support despite the deepening recession, condemns the development path taken after 1989 and openly rejects the wrong model of the last 20 years. The government intends to build a new economic model following a model, which one can call a model of economic nationalism as the only way out of the crisis. The paper intends to portray, through the case of Hungary, how economy and politics is interconnected, and why political elites are choosing a credit fuelled development path. The paper intends to portray how a credit fuelled growth was induced by politics and ended up in tears. Moreover, the paper describes the consequences of pro-etatist shift in the public sentiment due to the alleged “market-failure”, which was in reality a crisis, at first place, created for political purposes by political means. This article, based on the Austrian business cycle theory, argues that the tragedy of Hungary was that it went through a government inspired spending binge in the first half of the 2000s. The deficit spending of the government was accompanied by the expansion of credit by the commercial banks, mostly denominated in Swiss francs. The combined effect of deficit spending and credit expansion was the build-up of debt and loss of cost competitiveness. The 2008 crisis ended the credit fuelled development path and has started the long and painful period of deleveraging crisis. On the other hand, the Hungarian crisis is a post-Keynesian crisis. It had broken out when the state was already heavily indebted and

    We present results from ambient noise tomography applied to temporary seismological stations in the easternmost part of the Alps and their transition to the adjacent tectonic provinces (Vienna Basin, Bohemian Massif, Southern Alps, Dinarides). By turning each station into a virtual source, we recover surface waves in the frequency range between 0.1 and 0.6 Hz, which are sensitive to depths of approximately 2-15 km. The utilization of horizontal components allows for the analysis of both Rayleigh and Love waves with comparable signal-to-noise ratio. Measured group wave dispersion curves between stations are mapped to local cells by means of a simultaneous inverse reconstruction technique. The spatial reconstruction for Love-wave velocities fails in the central part of the investigated area, and we speculate that a heterogeneous noise source distribution is the cause for the failure. Otherwise, the obtained group velocity maps correlate well with surface geology. Inversion of Rayleigh-wave velocities for shear-wave velocities along a vertical N-S section stretching from the Bohemian Massif through the Central Alps to the Southern Alps and Dinarides reveals a mid-crustal low-velocity anomaly at the contact between the Bohemian Massif and the Alps, which shows a spatial correlation with the P-wave velocity structure and the low-frequency component of the magnetic anomaly map. Our study is validated by the analysis of resolution and accuracy, and we further compare the result to shear-wave velocity models estimated from other active and passive experiments in the area.

    High power laser fields enabled by technologies developed for ground-based gravitational-wave observatories open up new opportunities for fundamental physics studies. One of these options is the search for axions and axion-like particles in a pure laboratory experiment. The axion is a solution to the strong CP-problem and a potential dark matter candidate. The axion has also been proposed as an additional channel to cool stars as well as a potential explanation for the TeV transparency problem. The German-US ALPS collaboration is setting up a light-shining-through-walls (LSW) experiment at DESY. LSW experiments are based on the simple idea that a high power laser field traversing a static magnetic field will transform partly into a relativistic axion field. This axion field will travel through an opaque wall into a second static magnetic field region where it turns partly back into an electromagnetic wave field with the same frequency as the laser. The ALPS collaboration is working towards a large scale LSW experiment at DESY in Hamburg, Germany. I will report on the status of the ALPS experiment. This work is supported by the Deutsche Forschungsgemeinschaft, PRISMA, the Helmholtz Association, the National Science Foundation and the Heising-Simons Foundation.

    The Alps are particularly sensitive to global warming and warmed twice as much as the global average in the recent past. In addition, the Alps and its surroundings are a densly populated areas where society is affected by climate change in many ways, which calls for reliable estimates of future climate change. However, the complex Alpine region poses considerable challenges to climate models, which translate to uncertainties in future climate projections. Against this background, the present study reviews the state-of-knowledge about 21st century climate change in the Alps based on existing literature and additional analyses. It will be demonstrated that considerable and accelerating changes are not only to be expected with regard to temperature, but also precipitation, global radiation, relative humidity, and closely related impacts like floods, droughts, snow cover, and natural hazards will be effected by global warming. Under the A1B emission scenario, about 0.25 °C warming per decade until the mid of the 21st century and accelerated 0.36 °C warming per decade in the second half of the century is expected. Warming will most probably be associated with changes in the seasonality of precipitation, global radiation, and relative humidity. More intense precipitation extremes and flooding potential are particularly expected in the colder part of the year. The conditions of currently record breaking warm or hot winter or summer seasons, respectively, may become normal at the end of the 21st century, and there is indication for droughts to become more severe in the future. Snow cover is expected to drastically decrease below 1500 - 2000 m and natural hazards related to glacier and permafrost retreat are expected to become more frequent. Such changes in climatic variables and related quantities will have considerable impact on ecosystems and society and will challenge their adaptive capabilities.

    2014-01-01

    Forecasting the outcomes of national elections has become established practice in several democracies. In the present paper, we develop an economic voting model for forecasting the future success of the Austrian ‘grand coalition’, i.e., the joint electoral success of the two mainstream parties SPOE and OEVP, at the 2013 Austrian Parliamentary Elections. Our main argument is that the success of both parties is strongly tied to the accomplishments of the Austrian system of corporatism, that is, the Social Partnership (Sozialpartnerschaft), in providing economic prosperity. Using data from Austrian national elections between 1953 and 2008 (n=18), we rely on the following predictors in our forecasting model: (1) unemployment rates, (2) previous incumbency of the two parties, and (3) dealignment over time. We conclude that, in general, the two mainstream parties benefit considerably from low unemployment rates, and are weakened whenever they have previously formed a coalition government. Further, we show that they have gradually been losing a good share of their voter basis over recent decades. PMID:26339109

    Full Text Available We evaluated the effect of acidic deposition and nitrogen on Austrian forests soils. Until thirty years ago air pollution had led to soil acidification, and concerns on the future productivity of forests were raised. Elevated rates of nitrogen deposition were believed to cause nitrate leaching and imbalanced forest nutrition. We used data from a soil monitoring network to evaluate the trends and current status of the pH and the C : N ratio of Austrian forest soils. Deposition measurements and nitrogen contents of Norway spruce needles and mosses were used to assess the nitrogen supply. The pH values of soils have increased because of decreasing proton depositions caused by reduction of emissions. The C : N ratio of Austrian forest soils is widening. Despite high nitrogen deposition rates the increase in forest stand density and productivity has increased the nitrogen demand. The Austrian Bioindicator Grid shows that forest ecosystems are still deficient in nitrogen. Soils retain nitrogen efficiently, and nitrate leaching into the groundwater is presently not a large-scale problem. The decline of soil acidity and the deposition of nitrogen together with climate change effects will further increase the productivity of the forests until a limiting factor such as water scarcity becomes effective.

    Tractors, self-propelled harvesting machinery, and material handling machinery are the most commonly used self-propelled machineries in Austrian agriculture, and they have similarities in main accident scenarios. Statistical data of all occupational incidents with these machines reported between 2008 and 2010 were analyzed to obtain information about the circumstances of the incidents, and about the victims and their work environments. Criteria of recognized occupational incidents provided by the Austrian Social Insurance Institution for Farmers were analyzed according to machinery category by means of cross-tabulation and chi-square tests. The results were discussed and evaluated in the context of the literature. The results of the analysis of the databases show that 786 occupational incidents with tractors, self-propelled harvesting machinery, and material handling machinery occurred in Austrian agriculture between 2008 and 2010. There were 231 occupational incidents in 2008; the number rose to 268 in 2009 and to 286 in 2010. A total of 41 incidents were fatal. For the machinery categories analyzed, the majority of injured victims were male, older than 40 years, Austrian citizens, and managers of a mixed-agricultural farm. A large number of the incidents occurred in all machinery categories by loss of control during operating a vehicle.

    Rock glaciers and protalus ramparts are characteristic landforms of the periglacial domain often used as markers of the permafrost occurrence in mountain terrains. Therefore, relict rock glaciers can be used for paleoclimate reconstructions. We present here the first rock glacier inventory of south-eastern Alps (including the northeasternmost region of Italy and Slovenia) obtained through the use of high resolution orthophotos and high resolution digital terrain model interpolated from airborne laser scanning (LiDAR). We mapped 53 rock glaciers covering a total area of 3.45 km2. The majority of rock glaciers are classified as relict and distributed between 1,708 and 1,846 m a.s.l. with slope range between 19° and 27°. Their altitudinal range is the lowest for the southern Alps and comparable with what has been found for relict rock glaciers in the Northern Alps of Austria (1,798 m) and in the Austrian Niedere Tauern Range (1,823-1,850 m). Besides rock glaciers we also observed 66 protalus (pronival) ramparts covering 0.48 km2. They are predominantly located in the Carnic Alps, Julian Alps and Karavanke (80% of the total); the majority is distributed between 1,697 m and 2,007 m a.s.l. Protalus (pronival) ramparts situated in the Carnic Alps and Prealps (47% of the total) generally follow the same geographical distribution of rock glaciers, whereas more than half of the inventoried protalus (pronival) ramparts are located in the more maritime area of the Alps where there is the higher precipitation. The analysis also highlighted 9 pronival ramparts located in front of permanent snow/firn bodies and small glacierets. These ridges produce a damming effect for avalanches which enhance accumulation of winter snow, a significant impact to the local mass balance. Using paleoclimate reconstruction based on the existing 1981-2010 climatology of the area, we infer that the rock glaciers possibly formed during one of the dry and cold periods of the late Pleistocene (12.8±0

  11. Two centuries of the Austrian Civil code (1811-2011

    Directory of Open Access Journals (Sweden)

    Nikolić Dušan

    2011-01-01

    Full Text Available Austrian civil code (Allgemeines bürgerliches Gesetzbuch - ABGB, ACC succeeded in resisting the challenges of time for two centuries. A number of factors influenced it's longevity. First of all, prior to adoption of the law, a long lasting and well designed work, which has been described in greater detail in this article, was done. The Code was written gradually, with lots of recalculations, checks and public debates. In legal literature, it is often written about a unique lawmaking experiment, which Austrian authorities made by implementing the Code in one part of the state territory. The Code was written for feudal order, but according to principles of natural law. This second thing has, in addition to widely formulated and flexible legal norms, left enough space for extensive interpretation of outdated rules, and filling in the legal lacunas, whose number was increasing as the time passed. Courts often used this opportunity in a creative manner, contributing to survival of the Code. Many additions and changes were made to the Code, but there were few of those who thought that it should be changed by a new one Code. Austrians are preparing a more detailed revision of the ACC, which will allow modernization of the national law and it's synchronization with trends in current European law, but on the other hand, to preserve the two century old legal heritage. The second part of this article is dedicated to the influence of the Austrian Civil Code on the development of civil law in the former Yugoslavia and Serbia. ACC served as model for adoption of the Serbian Civil Code of 1844. It was applied as a positive law in the first half of XX century, in one part of the territory of today's Autonomous Province of Vojvodina. Formally, legal rules of the Austrian Civil Code can even be applied today, according to the Law on Nullity of Legal Regulations Enacted Prior to 6th of April 1941, and During the Enemy Occupation. However, that possibility is more

We used elastic plate modeling to reconsider the Moho fragmentation. We interpret subduction of EU below AD and PA from north to south...... and underthusting of AD mantle below PA from southwest to northeast. The Moho fragmentation correlates well with major upper crustal structures and is supported by gravity, seismic, and geodetic data. An analysis of crustal thickening suggests that active convergence is associated with continued thrusting...... and lateral extrusion in the central Eastern Alps and thickening of the Adriatic indenter under the Southern Alps.

    Since the discovery of the Neolithic glacier mummy "Ötzi" in the nival belt of the main Alpine ridge, the onset of alpine pasture is matter of a highly controversial debate both in archaeology and in palaeo-ecology of the Eastern Alps. The implication is that his sojourn in the high-altitudes of the Alps is considered to be connected with pastoral nomadism. Regrettably any archaeological evidence for the existence of such Neolithic alpine pastoral systems is missing up to now and the assumption is based on palynological data only. However, also the palynological record is ambiguous, because pasture indicators in the alpine regions react positive on grazing as well as on fertilization induced by a higher runoff of precipitation. Thus alpine pasture indicators reflect both grazing pressure and climatic change. Anyhow, alpine pastoral systems are a common practice in Alpine animal husbandry, but from an economic point of view such a seasonal vertical transhumance is costly. There are three main reasons for its practice: i) climatic, ii) economic (mainly in connection with population pressure or mining activities), and iii) cultural ideology. In this study we tested the above mentioned reasons in an interdisciplinary study on the beginning of pastoral activities in high altitudes in the central part of the Eastern Alps. This is conducted by palynological analyses of peat deposits situated in the vicinity of the timberline (1600 - 2400 m a.s.l.) combined with archaeological surveys. The investigated sites are located in traditional Alpine transhumance regions and aligned on a transect through the central part of the Eastern Alps. The studies reveal that grazing pressure is reflected since the Bronze Age, which is corroborated by archaeological findings in the vicinity of the investigated sites.

    Obedience and disobedience have always been salient issues for both civil society and social psychologists. Since Milgram's first studies on destructive obedience there has not been a bottom-up definition of what obedience and disobedience mean. The current study aimed at investigating the social representations young adults use to define and to co-construct knowledge about obedience and disobedience in Austria. One hundred fifty four (106 females, 68.8%) Austrian young adults (Mean age = 22.9; SD = 3.5) completed a mixed-method questionnaire comprising open-ended questions and free word associations. Overall obedience and disobedience are respectively defined as conformity and non-conformity to regulations, ranging from implicit social norms to explicit formal laws. Authority is multi-faceted and has a central role in orienting obedience and disobedience. Further fundamental determinants of the authority relationship and relevant application of the results are discussed in this paper.

    Full Text Available Market equilibrium is an illusion. The economic reality shows us that the main characteristic of the markets is the state of instability. The complexity of the phenomenon and the strong implications engendered by the economic fluctuations in the macro system, justify the rich scientific research activity of the main schools of economic thought to explain it. The Austrian school of economic thought has one of the most realistic analyses of the factors who generate the market instability.

    During prehistory fire-setting was the most appropriate technique for exploiting ore deposits. Charcoal fragments found in the course of archaeological excavations in a small mine called Mauk E in the area of Schwaz/Brixlegg (Tyrol, Austria) are argued to be evidence for the use of this technology. Dendrochronological analyses of the charcoal samples yielded calendar dates for the mining activities showing that the exploitation of the Mauk E mine lasted approximately one decade in the late 8th century BC. Dendrological studies show that the miners utilised stem wood of spruce and fir from forests with high stand density for fire-setting and that the exploitation of the Mauk E mine had only a limited impact on the local forests.

    2003-04-01

    Sediment cores from two lakes (Oberer and Unterer Landschitzsee) within the same drainage area and located slightly above and below the present day timberline, on the southern slopes of the central Austrian Alps, have been investigated using a multi-proxy approach. Transfer functions were constructed for diatoms (special emphasis being given to Fragilaria) and chrysophyte stomatocysts. The functions have been used to infer mean July water temperatures and the date of spring mixing, as based on a training set of thermistor recordings made in 45 lakes over a two year period. Other climate-driven environmental parameters which were reconstructed by transfer function studies are alkalinity and pH. In addition basic geochemical measurements, mineral magnetism, and pollen analyses were carried out on the sediment sequences. The period subsequent to the Younger Dryas (about 12000 cal. BP) is characterized by high alkalinity and low water temperatures, which in the earliest sediment records, were probably affected by glacial meltwater. Low water temperatures continued until 8000 cal. BP., due to a series of cold and wet climate oscillations. A marked temperature increase of about 3^o C followed between 8000 and 7400 cal. BP., paralleled by an increase in alkalinity and pH. Subsequently to about 6000 cal. BP. there followed a long-term trend of increasing humidity climaxing, at about 3000 cal. BP, in a series of oscillations between colder (and probably wetter) periods and warmer phases. A decline in pH mirrors this long-term trend in increasing humidity. Lowered pH appears to have been affected by temperature decline and/or melt-water impact during the more extreme events. Alpine land-use at Unterer Landschitzsee started about 3500 cal. BP and intensified during the Keltic/Roman and Medieval periods; these phases of enhanced anthropogenic impact are found to be closely related to climatic ameliorations. Changes in geochemistry (e.g., C/N and Fe/Mn ratios) relate to a

    Autoimmune lymphoproliferative syndrome (ALPS), a disorder characterized by immune dysregulation due to disrupted lymphocyte homeostasis, is mainly resulted from the mutations in FAS-mediated apoptotic pathway. In addition, other mutations of the genes such as Fas-ligand (FASLG), Caspase 10 (CASP10) and Caspase 8 (CASP8), NRAS and KRAS have also been observed in a small number of patients with ALPS or ALPS-related disorders. However, approximately 20-30% of patients with ALPS have unidentified defect. Its clinical manifestations observed in multiple family members include unexplained lymphadenopathy, hepatosplenomegaly, autoimmune cytopenias such as thrombocytopenia, neutropenia, and anemia due to excessive production of antibodies by lymphocytes, elevated number of double-negative T (DNT) cells, and increased risk of lymphoma. As a very rare disease, ALPS was first characterized in the early 1990s. More than 300 families with hereditary ALPS have been reported till now; nearly 500 patients from these families have been studied and followed worldwide over the last 20 years. ALPS has historically considered as a primary immune defect presenting in early childhood, however, recent studies have shown that it may be more common than previous thought because adult onset presentation is increasingly becoming recognized and more adult ALPS patients are diagnosed. The new genetic and biological insights have improved the understanding of ALPS and a number of targeted therapeutic strategies such as mycophenolate mofetil, sirolimus, and pentostatin have been successfully applied in ALPS patients with promising treatment efficacy. This article comprehensively reviews the clinical and laboratory manifestations, new research advances in the molecular pathogenesis, diagnosis and treatments of this disorder.

    Dendrogeomorphic dating of historical debris-flow events is a highly valuable tool for improving historical records in the field of natural hazard management. Previous dendrogeomorphic investigations generally have focused on case studies of single torrents; however, regional investigations may offer a more accurate reconstruction of regional patterns of activity and therefore may have an advantage over individual cases. The aim of the study is to provide a regional reconstruction of debris-flow events for a site in the Northern Calcareous Alps of western Austria (Gamperdonatal, Vorarlberg) and to document spatial and temporal morphological changes in individual and neighboring torrents. Analysis of 442 trees (268 Pinus mugo ssp. uncinata, 164 Picea abies, and 10 Abies alba) allowed identification of 579 growth disturbances corresponding to 63 debris-flow events since A.D. 1839. The majority of growth disturbances were in the form of growth suppression or release (76%) owing to the nature of both the deposited material and the process characteristics. Regional patterns of event frequency indicated a paucity of activity in the early to mid-twentieth century and increased activity since A.D. 1948, whereby large events were followed by subsequent years of continued activity of smaller magnitude. Patterns of frequency could be attributed primarily to spatiotemporal changes in channel morphology, but may also be reflective of changes in transport conditions within the valley. This study provides the first regional investigation in the Austrian Alps and contributes to the documentation of tree responses to geomorphic disturbances in calcareous material.

    Full Text Available Abstract In the 17th century, brown bears (Ursus arctos were still abundant and widely distributed over the entire alpine area of northern Italy and even in large, dense forests of the prealps and the Po plain. The start of the decline coincided with increasing deforestation for farming at the end of the 18th century and, in the 19th century, increased access to previously remote wilderness areas of the prealpine and alpine mountains, where direct persecution by farmers and hunters caused the extinction of local bear populations. The last remnant population that occupied the Adamello-Brenta Alps was considered biologically extinct since 1989 (only three, non-reproducing bears. Here we present an analysis of the reintroduction process as the most suitable tool for brown bear recovery in the Italian Alps, taking into account both the benefits of reinstating a viable population and the risks that the coexistence between man and bear could cause. The reintroduction process is discussed aiming at an evaluation of its contribution to the global future efforts for brown bear conservation in the alpine region. A GIS-based habitat suitability analysis was implemented to test for good-quality bear habitat in a vast mountainous area around the Adamello-Brenta Natural Park (6500 km², the release site of bears. The model was based on presence/absence data, gathered over the last 20 years, and habitat parameters in 25 ha cells in the core-area of the remnant bear population (645 km² study area. Other parameters of human disturbance and livestock densities, were considered at the scale of the municipality. Bears positively selected deciduous forest but seemed to avoid areas with intensive pasture activity, mainly of horses and sheep, despite the latter being a potential prey. Habitats containing large amounts of bare rock, farmland and urbanised areas were avoided. There were no significant

    Full Text Available Abstract To evaluate the population trend of lynx in the Swiss Alps, we analysed the spatial and numerical development of signs of presence found from 1995 to 1999 and compared them with previous years. Three sources of information on the presence of lynx are available: (1 reports of lynx killed or found dead; (2 records of livestock killed by lynx; (3 records of wild prey remains, tracks, scats, sightings, and vocalisations. We distinguished three levels of reliability: Quality 1 represent the hard facts, e.g. all reports of lynx killed or found dead, photographs of lynx as well as young orphaned lynx caught in the wild and taken into captivity. Quality 2 include all records of livestock killed, wild prey remains, tracks and scats reported by people who have attended special courses, e.g. mainly game wardens. Quality 3 are all wild prey remains and tracks reported by the general public as well as all sightings, scats and vocalisations, e.g. signs that cannot be verified. More than 1600 signs of presence were recorded in the Swiss Alps in this 5-year-period. A high number of quality 1 and 2 records showed that (1 the lynx population in the north-western Swiss Alps increased from 1994 to 1999, that (2 there is a moderate presence of the species in the central and south-western parts and (3 none or hardly any lynx are found in the eastern Alps of Switzerland. Based on a radio-telemetry study and the number of quality 2 data, we were able to estimate the number of lynx in the Swiss Alps at 70 individuals. To counterpart the uneven distribution of lynx in Switzerland, lynx are being translocated from the north-western Alps to the eastern Swiss Alps, as the expansion of the Swiss lynx population is crucial for the conservation of the lynx in the whole Alps.

    2010-05-01

    The Austrian Agency for Health and Food Safety (AGES) stores comprehensive data sets of radionuclide contents in Austrian groundwater. There are several analyses concerning Rn-222, Ra-226, gross alpha and gross beta as well as selected analyses of Ra-228, Pb-210, Po-210, Uranium and U-234/U-238. In a current project financed by the Austrian Federal Ministry of Agriculture, Forestry, Environment and Water Management, AGES and the Geological Survey of Austria (GBA) are evaluating these data sets with regard to the geological backgrounds. Several similar studies based on groundwater monitoring have been made in the USA (for instance by Focazio, M.J., Szabo, Z., Kraemer, T.F., Mullin, A.H., Barringer, T.H., De Paul, V.T. (2001): Occurrence of selected radionuclides in groundwater used for drinking water in the United States: a reconnaissance survey, 1998. U.S. Geological Survey Water-Resources Investigations Report 00-4273). The geological background for the radionuclide contents of groundwater will be derived from geological maps in combination with existing Thorium and Uranium analyses of the country rocks and stream-sediments and from airborne radiometric maps. Airborne radiometric data could contribute to identify potential radionuclide hot spot areas as only airborne radiometric mapping could provide countrywide Thorium and Uranium data coverage in high resolution. The project will also focus on the habit of the sampled wells and springs and the hydrological situation during the sampling as these factors can have an important influence on the Radon content of the sampled groundwater (Schubert, G., Alletsgruber, I., Finger, F., Gasser, V., Hobiger, G. and Lettner, H. (2010): Radon im Grundwasser des Mühlviertels (Oberösterreich) Grundwasser. - Springer (in print). Based on the project results an overview map (1:500,000) concerning the radionuclide potential should be produced. The first version should be available in February 2011.

    Religion is known to be a protective factor against suicide. However, religiously affiliated sexual minority individuals often report a conflict between religion and sexual identity. Therefore, the protective role of religion against suicide in sexual minority people is unclear. We investigated the effect of religion on suicide risk in a sample of 358 lesbian, gay and bisexual Austrians. Religion was associated with higher scores of internalized homophobia, but with fewer suicide attempts. Our data indicate that religion might be both a risk and a protective factor against suicidality in religiously affiliated sexual minority individuals.

    20 years ago, Michael Schnitzler founded the NGO "Rainforest of the Austrians" to help save one of the most diverse rainforests in Central America, the Esquinas rainforest on the Pacific coast of SW Costa Rica, from being destroyed through logging. In this abstract we present an interdisciplinary upper Austrian school project aiming at building positive awareness in pupils towards rainforest conservation by fund-raising to help purchase endangered forest areas. The acquired rainforest was donated to the Costa Rican government and became part of the National Park "Piedras Blancas". In the following, we present a chronology of events and actions of the school project. We started our rainforest project by face-to-face encounters, letting involved persons speak directly to the pupils. Dr. Huber, coordinator of the tropical rainforest station La Gamba in Costa Rica (www.lagamba.at), together with Dr. Weissenhofer, presented an introductory slide show about the "Rainforest of the Austrians". With rainforest images and sounds in their mind the pupils wrote "trips of a lifetime" stories, thus creating idyllic images of rainforest habitats. Following up on that, we visited the exhibition "Heliconia and Hummingbirds" at the Biology Center in Linz. Reports about the slide show and the exhibition followed. Tropical sites were compared by producing climate graphs of La Gamba, Costa Rica, and Manaus in Brazil. The global distribution and the decrease of rainforests were also analyzed. In biology lessons the symbiosis between plants and animals of the rainforest were worked out by searching the Internet. Flyers with profiles of rainforest animals were produced. We also discussed the ecotourism project "RICANCIE" in Ecuador using fact sheets. "RICANCIE" is a Spanish acronym standing for "Indigenous Community Network of the Upper Napo for Intercultural Exchange and Ecotourism". It was founded in 1993 aiming to improve the quality of life for some 200 indigenous Kichwa families

    2014-12-01

    Full Text Available In 1775, the territory of Bucovina became part of the Habsburg monarchy and it stayed like that for 143 years. All throughout this period when the Romanians lived here next to Ukrainians, Germans, Jews and other nationalities, the Austrian government took into consideration their need for culture, which resulted in the development of a multicultural teaching system. This implied that the languages of teaching in the Bukovinian schools were: Latin, Greek, Romanian, Ukrainian and, more often than not, German. Although the weighty presence of the German language in the academic institutions limited the number of young Romanians in schools, the teaching in German enabled the access of the Bukovinian students to the great European universities from Vienna, Salzburg, Lemberg, Kraków or Prague, before the founding of the Chernivtsi University (1875. Thus, beyond the negative aspects of the separation of this territory from Romania, the Austrian occupation represented an effervescent period from a cultural viewpoint, which lent a specific identity to the teaching system in Bukovina.

    observed in Obir Caves. From May to the end of July the data were characterised by a series of irregular high energy anomalies, lasting from hours to days, along with a series of regular nightly anomalies which are thought to relate to the VLF transmitters. From the beginning of August to October the data were characterised (except for the artificial nightly signals) by relative quiescence of other signals with only a few distinct anomalies. Data relating to rock deformation along active tectonic faults is also recorded at Zbrašov Aragonite Caves and Obir Caves using a type of automated moiré extensometer called a TM-71. These data have been interrogated alongside other environmental factors such as seismicity, precipitation, earth tides, and extraterrestrial magnetic radiation (all data provided by the Central Institution for Meteorology and Geodynamics (ZAMG)). It has been possible to compare all the phenomena with our data of natural electromagnetic activity. This pilot study was supported by the Institute of Physics at the Brno University of Technology, the Institute of Rock Structure & Mechanics CAS, and the Austrian Science Foundation (Project P25884-N29 "Active tectonics and recent dynamics of microdisplacements along major fault systems of the Eastern Alps registered in caves (SPELEOTECT)".

    Full Text Available Upper Triassic basin-platform succession in the Kamnik-Savinja Alps (N-central Slovenia is similar to the succession known from the Julian Alps (Martuljek Mountain Group. It was part of the same Late Triassic depositional edifice, with the progradation of the Dachstein Platform in the SW-NE direction (recent orientation from Julian Alps toward the Kamnik-Savinja Alps. Tectonic blocks with the same/similar stratigraphic record, were displaced as a consequence of the Alpine and later tectonic displacements. In the Kamnik-Savinja Alps, the upper part of the Martuljek platy limestone was dated with the conodonts as Late Carnian – Early Norian in the Mt. Ko~na. In the Mt. Skuta area, Limestone with chert is positioned above Martuljek platy limestone and under the Dachstein carbonate platform. Uppermost part of the Limestone with chert is Late Norian. Mutual vertical and lateral relationship, age of the lithological units, especially upper part of the deeper-water limestone, points to the progradation of the Dachstein carbonate platform in the Early Norian and possible aggradation in the part of the Middle and in the Late Norian.

  15. Shaping Disciplinary Boundaries: Scientific Practice and Politics in the Methodenstreit Between the German Historical School and the Austrian School of Economics

    Science.gov (United States)

    de Sousa, Filomena

    In view of the great success enjoyed by the natural sciences by the end of the nineteenth century, scholars working in the social field felt the need to highlight the importance of the human sciences as piece and part of the broad scientific scene. Discussions purporting to the limits and status of the sciences devoted to the study of human behaviour, especially in relation to the logic of the natural sciences, led to the articulation of the conceptual pair Erklären/Verstehen as corresponding to the demarcation between Naturwissenschaften and Geisteswissenschaften. The differentiation between History and Society took central stage in the context of the debates about the scientific parameters shaping disciplinary boundaries and gave rise to the famous Methodenstreit opposing Gustav Schmoller the leader of the German Younger School of Economics to Carl Menger, the founding father of the Austrian School of Economics. The relevance of this episode can be measured by its impact not only on economics, but on the broader context of twentieth century social science, as the Methodenstreit turned on the dispute between Methodological Individualism and Holism. In this essay I tell the story of the divergences between German and Austrian scholars and suggest that the gap between the German Historical School and the Austrian School of Economics may be narrower than standard textbooks suggest.

  17. A Thought Experiment Comparing Austrian and Keynesian Stimulus Packages

    Directory of Open Access Journals (Sweden)

    Wladimir Kraus

    Full Text Available Essentially, there are two competing views of how to overcome an economy-wide recession/depression. The Austrian view understands the free-play of competition as the most potent means to overcome the short-run mismatch between an excessive boom-level of nominal wages/prices and depressed crisis-level volume of aggregate spending. In the Keynesian view, the disastrous mismatch between desired saving and planned investment inherent in capitalist economies requires the government to step in and take up the burden of spending to infuse the lacking demand for products and labor.The thought experiment presented in the paper is designed to provide the reader with a direct comparison of major analytical claims of the two competing approaches to assess the ability of each of the two to affect, positively or negatively, employment, capital accumulation, and the general standard of living/real wages.

    2010-06-01

    Rescaled range and power spectral density analysis are applied to examine a diverse set of macromonetary data for fractal character and stochastic dependence. Fractal statistics are used to evaluate two competing models of the business cycle, Austrian business cycle theory and real business cycle theory. Strong evidence is found for antipersistent stochastic dependence in transactions money (M1) and components of the monetary aggregates most directly concerned with transactions, which suggests an activist monetary policy. Savings assets exhibit persistent long memory, as do those monetary aggregates which include savings assets, such as savings money (M2), M2 minus small time deposits, and money of zero maturity (MZM). Virtually all measures of economic activity display antipersistence, and this finding is invariant to whether the measures are adjusted for inflation, including real gross domestic product, real consumption expenditures, real fixed private investment, and labor productivity. This strongly disconfirms real business cycle theory.

    The Any Light Particle Search II (ALPS II) is an experiment that utilizes the concept of resonant enhancement to improve on the sensitivity of traditional light shining through a wall style experiments. These experiments attempt to detect photons passing through an opaque wall by converting to relativistic weakly interacting sub-eV particles and then reconverting back to photons. ALPS II at DESY in Hamburg, Germany will use dually resonant optical cavities before and after the wall to increase the probability of this interaction occurring. This paper gives a technical overview and status report of the experiment.

    The automatic lung parameter estimator (ALPE) method was developed in 2002 for bedside estimation of pulmonary gas exchange using step changes in inspired oxygen fraction (FIO₂). Since then a number of studies have been conducted indicating the potential for clinical application and necessitating systems evolution to match clinical application. This paper describes and evaluates the evolution of the ALPE method from a research implementation (ALPE1) to two commercial implementations (ALPE2 and ALPE3). A need for dedicated implementations of the ALPE method was identified: one for spontaneously breathing (non-mechanically ventilated) patients (ALPE2) and one for mechanically ventilated patients (ALPE3). For these two implementations, design issues relating to usability and automation are described including the mixing of gasses to achieve FIO₂ levels, and the automatic selection of FIO₂. For ALPE2, these improvements are evaluated against patients studied using the system. The major result is the evolution of the ALPE method into two dedicated implementations, namely ALPE2 and ALPE3. For ALPE2, the usability and automation of FIO₂ selection has been evaluated in spontaneously breathing patients showing that variability of gas delivery is 0.3 % (standard deviation) in 1,332 breaths from 20 patients. Also for ALPE2, the automated FIO2 selection method was successfully applied in 287 patient cases, taking 7.2 ± 2.4 min and was shown to be safe with only one patient having SpO₂ < 86 % when the clinician disabled the alarms. The ALPE method has evolved into two practical, usable systems targeted at clinical application, namely ALPE2 for spontaneously breathing patients and ALPE3 for mechanically ventilated patients. These systems may promote the exploration of the use of more detailed descriptions of pulmonary gas exchange in clinical practice.

    This article is a historiographical exploration of the experiences that German and Austrian émigré psychiatrists and neurologists made in Great Britain since 1933, after the Nazi Governments in Central Europe had ousted them from their positions. When placing these occurrences in a wider historiographical perspective, the in-depth analysis provided here also describes the living and working conditions of the refugee neuroscientists on the British Isles. In particular, it looks at the very elements and issues that influenced the international forced migration of physicians and psychiatrists during the 1930s and 1940s. Only a fraction of refugee neuroscientists had however been admitted to Britain. Those lucky ones were assisted by a number of charitable, local, and academic organizations. This article investigates the rather lethargic attitude of the British government and medical circles towards German-speaking Jewish refugee neuroscientists who wished to escape Nazi Germany. It will also analyze the help that those refugees received from the academic establishment and British Jewish organizations, while likewise examining the level and extent of the relationship between social and scientific resentments in Great Britain. A special consideration will be given to the aid programs that had already began in the first year after the Nazis had seized power in Germany, with the foundation of the British Assistance Council by Sir William Henry Beveridge (1879-1963) in 1933.

  10. The Effects of the Planned High-Speed Rail System on Travel Times and Spatial Development in the European Alps

    2017-02-01

    Full Text Available One of the direct effects of introducing high-speed railway lines is a significant reduction in travel times between major cities. This is particularly relevant in mountain areas. It not only makes cities more easily reachable with more sustainable transport systems but can also encourage different travel behavior and reduce environmental pressures on sensitive areas. A comprehensive analysis of the spatiotemporal effects of the introduction of high-speed railways in the Alpine arc has not yet been developed. To help fill this gap, this study uses multidimensional scaling and the geographical information system to illustrate the time–space compression. This term indicates the erosion of spatial and temporal distances in the areas of the Alps directly affected by the new railway lines. Six trans-Alpine high-speed railway lines are analyzed, comparing current and projected travel times by train. A time-based map is created to show the time–space compression in every transversal direction, particularly on the French and the Austrian side of the Alps. Implications in terms of local accessibility are also analyzed, focusing on the Autonomous Province of Bolzano/Bozen-South Tyrol. Finally, the paper discusses the importance of time-based maps for the understanding of sociospatial dynamics and the possible implications for spatial development.

    Stable isotope compositions have been determined for serpentinites from between Davos (Arosa-Platta nappe, Switzerland) and the Valmalenco (Italy). ??D and ??18O values (-120 to -60 and 6-10???, respectively) in the Arosa-Platta nappe indicate that serpentinization took place on the continent at relatively low temperatures in the presence of limited amounts of metamorphic fluids that contained a component of meteoric water. One sample of chrysotile has a ??18O value of 13??? providing evidence of high W/R ratios and low formation temperature of lizardite-chrysotile in this area. In contrast, relatively high ??D values (-42 to -34???) and low ??18O values (4.4-7.4???) for serpentine in the eastern part of the Valmalenco suggest a serpentinization process that took place at moderate temperatures in fluids that were dominated by ocean water. The antigorite in the Valmalenco is the first reported example of continental antigorite with an ocean water signature. An amphibole sample from a metasomatically overprinted contact zone to metasediments (??D=-36???) indicates that the metasomatic event also took place in the presence of ocean water. Lower ??D values (-93 to -60???) of serpentines in the western part of the Valmalenco suggest a different alteration history possibly influenced by fluids associated with contact metamorphism. Low water/rock ratios during regional metamorphism (and metasomatism) have to be assumed for both regions. ?? 1988 Springer-Verlag.

    Biomass utilization is seen as one of various promising strategies to reduce additional carbon emissions. A recent project on potentials of biochar to mitigate climate change (FOREBIOM) goes even a step further towards bioenergy in combination of CCS or "BECS" and tries to assess the current potentials, from sustainable biomass availability to biochar amendment in soils, including the identification of potential disadvantages and current research needs. The current report represents an outcome of the 1st FOREBIOM Workshop held in Vienna in April, 2013 and tries to characterize the Austrian perspective of biochar for climate change mitigation. The survey shows that for a widespread utilization of biochar in climate change mitigation strategies, still a number of obstacles have to be overcome. There are concerns regarding production and application costs, contamination and health issues for both producers and customers besides a fragmentary knowledge about biochar-soil interactions specifically in terms of long-term behavior, biochar stability and the effects on nutrient cycles. However, there are a number of positive examples showing that biochar indeed has the potential to sequester large amounts of carbon while improving soil properties and subsequently leading to a secondary carbon sink via rising soil productivity. Diversification, cascadic utilization and purpose designed biochar production are key strategies overcoming initial concerns, especially regarding economic aspects. A theoretical scenario calculation showed that relatively small amounts of biomass that is currently utilized for energy can reduce the gap between Austria's current GHG emissions and the Kyoto target by about 30% if biomass residues are pyrolized and biochar subsequently used as soil amendment. However, by using a more conservative approach that is representing the aims of the underlying FOREBIOM project (assuming that 10% of the annual biomass increment from forests is used for biochar

    Relict rock glaciers provide information on past discontinuous permafrost and former mean annual air temperatures. A lack of records showing former permafrost distribution along the northern Alpine fringe prompted the investigation and numerical dating of a belt of relict rock glaciers in the Karwendel Mountains of the Northern Calcareous Austrian Alps. In two neighbouring cirques that were still glaciated during the early Younger Dryas, eleven 36Cl exposure ages from boulder surfaces were obtained. The ages imply the onset of rock glacier activity around ~ 12.3 ka with subsequent stabilization and permafrost melt out no later than ~ 10.1 ka. Hence, rock glacier formation coincided with glacier retreat in the cirques around the mid-Younger Dryas and continued into the early Holocene. As permafrost induced features, the rock glacier termini indicate the local past lower limit of discontinuous permafrost in open cirque floors at ~ 2000 m asl, which is around 400 m lower than during the mid-twentieth century at comparable locations in the Karwendel Mountains. Thus, a mean annual air temperature reduction of ~- 2.6 to - 3.8 °C relative to the mid-twentieth century is inferred. Based on a minimum glacier equilibrium line altitude in the cirques, a summer temperature reduction of less than - 2.6 to - 1.8 °C is shown, suggesting an increased seasonality at the time of rock glacier activity.

  15. Holocaust Studies in Austrian Elementary and Secondary Schools

    2016-09-01

    Full Text Available This article presents arguments in support of teaching about the Holocaust and Nazism in Austria at an early age. To accomplish this, Austrian and German elementary school textbooks were analyzed for the amount of content dealing with the Holocaust and Jews; the results showed that since 1980 the amount of content on the Holocaust increased in Germany, and to a lesser extent in Austria. The article reviews some of the criticism in Europe of the term Holocaust Education and explores some of arguments about why that is. The author argues that moral education and teaching of Human Rights are important components of, but ought not be the main goal of teaching about the Holocaust. The role of Austria after World War II, and exploration of the so called victim myth, prevalent until the 1990s are important to understanding history and to how history textbooks were created. After a discussion of how the Holocaust can be taught to elementary and early secondary school aged children, some suggestions are made about approaches to teaching the Holocaust to students in these age groups.

  16. The new Austrian tunnelling method in coal mining

    1987-12-03

    The new Austrian tunnelling method (NATM), as a composite support and lining system of bolts, steel mats and shotcrete, prevents the deconsolidation of the strata and activates the self-supporting properties of the strata envelope. By bringing in the strata for support it provides an exceptionally high support resistance, which outdoes steel supports and which is needed at increasing depths with their predictable high rock pressures and with large cross-sections in rooms where the limits of conventional steel arches are exceeded. Even thin shotcrete casing has a high support resistance. Where effects of other workings are present the NATM can be relied upon to have good stability over a long period and to be repair-friendly, as flaking off the casing can be made good by re-bolting and re-spraying. In contrast with the costly changing of entire support arches, partial surfaces can be repaired as required. The NATM is particularly cost-effective in the construction of drainage roads, which have to be lined against aggressive water, shaft porches, branch-offs, large rooms such as workshops, landings, belt drive rooms with internal cross-sections of 25 to 30 m/sup 2/ and shaft widening and traversing with irregular cross-sections. In geologically extremely difficult levels, such as those of the Laura and Zollverein 7/8 seams, the NATM has also been successfully used to construct drainage roads, branch-offs and shaft traverses. 30 refs., 8 figs., 6 tabs.

    The Salmon-Trinity Alps Wilderness in the Klamath Mountains province occupies an area of about 648 sq mi in parts of Trinity, Siskiyou, and Humboldt Counties, northwestern California. As a result of field studies it was determined that the Salmon-Trinity Alps Wilderness has an area with substantiated potential for gold resources in known lode deposits. Small amounts of quicksilver have been produced from one mine but there is little promise for the discovery of additional mercury resources. Geochemical sampling showed that anomalously high amounts of several other metals occur in a few places, but there is little promise for the discovery of energy or mineral resources other than mercury and gold.

  18. Ice cap melting and low viscosity crustal root explain narrow geodetic uplift of the Western Alps

    Science.gov (United States)

    Chery, Jean; Genti, Manon; Vernant, Philippe

    2016-04-01

    More than 10 years of geodetic measurements demonstrate an uplift rate of 1-3 mm/yr of the high topography region of the Western Alps. By contrast, no significant horizontal motion has been detected. Three uplift mechanisms have been proposed so far: (1) the isostatic response to denudation. However this process is responsible for only a fraction of the observed uplift and (2) the rebound induced by the Wurmian ice cap melting. This process leads to a broader uplifting region than the one evidenced by geodetic observations. (3) a deep source motion associated with slab motion or some deep isostatic unbalance. Using a numerical model accounting for crustal and mantle rheology of the Alps and its foreland, we model the response to Wurmian ice cap melting. We show that a crustal viscosity contrast between the foreland and the central part of the Alps, the later being weaker with a viscosity of 1021 Pa.s, is needed to produce a narrow uplift. The vertical rates are enhanced if the strong uppermost mantle beneath the Moho is interrupted across the Alps, therefore allowing a weak vertical rheological anomaly thanks to the continuity between the low viscosity parts of the crust and mantle.

    The Eastern Alps were formed by the north-south directed collision of the Adriatic (African) and European plates and a subsequent tectonic escape of crustal fragments to the unconstrained margin in the east, represented by the Pannonian Basin. Recent controlled source seismic experiments (TRANSALP, CELEBRATION 2000, and ALP 2002) revealed significant internal structures of the crust and the Moho topography. However, deeper plate tectonic structures (e.g. subducting slab) are still under debate. ALPASS is a passive seismic monitoring project aiming to reveal lower lithosphere and upper mantle beneath the wider Eastern Alpine region, and to contribute to a better understanding of the geodynamic processes at work. By cooperation of Austria, Croatia, Finland, Hungary, Poland, and USA 57 temporary seismic recording stations were deployed from May 2005 until May 2006. The layout was designed to extend the efforts of earlier experiments (e.g. TRANSALP) and to support two other passive seismic experiments (BOHEMA, Carpathian Basin Project), which are overlapping in the investigation area. Additionally, data from permanent networks was collected to improve coverage of the investigation area. 144 events (50% with M > 5.6) from epicentre distances between 30° and 100° were selected for teleseismic inversion. Travel time picking of P-wave arrivals has been done by a semi-automatic correlation technique. Crustal corrections benefit from the high resolution velocity model of the crust and the new Moho map derived from CELEBRATION 2000 and ALP 2002 data. First results of teleseismic inversion will be presented and discussed with respect to crustal structures revealed by the controlled source experiments, tomographic models generated during earlier studies, and their consequences for the conception of plate tectonics in the Eastern Alps.

  20. Holocene Glacier Fluctuations In The Swiss Alps

    Science.gov (United States)

    Holzhauser, H.

    The reconstruction of preindustrial glacier fluctuations in the Swiss Alps reveals the natural range of Holocene climate variability against which the present-day climatic situation can be judged. The results of very recent research on the Great Aletsch and Gorner Glaciers (Valaisian Alps), the Lower Grindelwald Glacier (Bernese Alps) shed light on the glacier fluctuations during the last 3200 years. These glaciers have, at max- imum extensions, penetrated below the timberline and have even reached inhabited areas resulting in sometimes massive destruction. Losses of buildings, woods and pas- tures are the conditions governing the methods used for the reconstruction of glacier length fluctuation through time. The main methods are: historical - the interpretation of pictorial and written historical records, glazio-archaeology - the search for anthro- pogenic traces that are directly related to changes in glacier size/length and scientific - the radiocarbon dating of fossil soils (palaeosols) and wood found in glacier fore- fields. Numerous samples of palaeosols and fossil wood (tree trunks, roots and macro- remains) found in the glacier forefield were radiocarbon dated. Owing to the good condition of several fossil tree trunks, dendrochronological analyses were also con- ducted. The dendrochronological analysis of fossil trees has supplied much reliable evidence of glacier fluctuations through its proven exactness (a single year resolution) which is impossible to obtain with the radiocarbon method alone.

  1. Impacts of Austrian Climate Variability on Honey Bee Mortality

    Global food production, as it is today, is not possible without pollinators such as the honey bee. It is therefore alarming that honey bee populations across the world have seen increased mortality rates in the last few decades. The challenges facing the honey bee calls into question the future of our food supply. Beside various infectious diseases, Varroa destructor is one of the main culprits leading to increased rates of honey bee mortality. Varroa destructor is a parasitic mite which strongly depends on honey bee brood for reproduction and can wipe out entire colonies. However, climate variability may also importantly influence honey bee breeding cycles and bee mortality rates. Persistent weather events affects vegetation and hence foraging possibilities for honey bees. This study first defines critical statistical relationships between key climate indicators (e.g., precipitation and temperature) and bee mortality rates across Austria, using 6 consecutive years of data. Next, these leading indicators, as they vary in space and time, are used to build a statistical model to predict bee mortality rates and the respective number of colonies affected. Using leave-one-out cross validation, the model reduces the Root Mean Square Error (RMSE) by 21% with respect to predictions made with the mean mortality rate and the number of colonies. Furthermore, a Monte Carlo test is used to establish that the model's predictions are statistically significant at the 99.9% confidence level. These results highlight the influence of climate variables on honey bee populations, although variability in climate, by itself, cannot fully explain colony losses. This study was funded by the Austrian project 'Zukunft Biene'.

    The 5th Hungarian-Austrian Workshop on Celestial Mechanics took place from 9th until the 10th of April 2010 in Vienna, Austria. The workshop was held in the Institute for Astronomy of Vienna University. From the Eötvös University and from the host institute experts and PhD students gathered together to discuss the challenges and new results of the actual problems of celestial mechanics. The workshop was held in the meeting room at the Sternwarte of the Vienna University located in a magnificent park in the heart of Vienna. Following the themes of the four previous events the focus for this workshop ranged from the Trojan problem, dynamics in binary star systems and exoplanetray systems. We were pleased to acknowledge the support of the host university. The talks were characterized by a large spectrum, which is typical of the workshops on celestial mechanics. Several talks discussed different aspects of the trojan problem, such as the three Trojan Problem, dynamics of trojan-like planets in binary stars, the frequencies of their motion around the triangular lagrangian points, etc. Several speakers focused on the formation of planetary systems and on the field of exoplanetary systems, like exoplanetary systems in higher order mean motion resonances, formation of planets in binary systems, stability of exomoons etc. Some of the presentation used sophisticated mathematical tools in order to understand mean motion resonances, the Sitnikov problem applying the KAM and the Nekhoroshev theorem. The theme of a number of talks was the motion of Solar System bodies: dynamics of the newly discovered moons of Pluto and of near-Earth asteroids. General problems were also addressed, among others chaos in Hamiltonian systems, adaptive Lie-integration method and iterative solution approximation to the generalised Sitnikov problem.

    Full Text Available The number of recognized accidents during agricultural work is still very high in Austria. In the years 2008 to 2009, there occurred 84 approved work accidents with mowing machines. The main causes of accidents were the loss of control of machines, transportations or conveyances, hand tools, objects or animals. In the literature, numerous studies of general agricultural and forestry accident situations are available. Detailed studies on specific types of agricultural machines, which describe concrete circumstances and causes of accidents, are in limited numbers. The accident database from the General Accident Insurance Institution and the Austrian Social Insurance Institution of Farmers, with personal and accidental data information about mowing machine accidents, were analyzed. The results showed that most accidents occurred on mixed agricultural farms (68%. The majority of the injured persons were male (86%, over 40-years-old (86% with an agricultural or forestry education (91%. The most common accidents occurred in the summer months (69% and on afternoons during the working week (79%. The majority of accidents were caused by contact with the machine (55% and the loss of control (73% during their operation (60% and harvesting work (63%. The most frequently injuries were wounds, fractures and superficial injuries (81% to the upper and lower extremities (66%. The results of the chi-square test showed significant correlations between the specific task with the form of contact, the working process, the day and season. Results of the odds ratio determination showed an increased risk of suffering serious injury for men in the first half of the year and half of the day due to loss of control over the machine during agricultural harvesting work.

    Full Text Available No Austrians in South Tyrol? Why the German-speaking community in Italy’s South Tyrol (Alto Adige province is not usually called an Austrian minority The article discusses the question why the German-speakers in Northern Italy’s South Tyrol province are only very rarely referred to as an Austrian minority, in spite of the fact that they were split off from Austria, and not Germany, in the aftermath of World War I. An analysis of the naming of German-speaking South Tyroleans in German, Austrian, Italian and English-speaking news media, which demonstrates a preference for terms such as “German-speaking minority” or “German minority” over “Austrian minority and equivalents, is followed by a discussion of three hypotheses to account for the situation. The author shows how the question of how to name the German-speaking South Tyroleans is closely intertwined with the issue of Austrian national identity and its re-orientation away from Germany in the aftermath of the Second World War. The author comes to the conclusion that the minority is not usually referred to as Austrian both due to the fact that it is difficult to include them in the young (civic Austrian nation in a logically consistent manner, and due to the German-speaking South Tyroleans’ own inconsistent self-identification as Austrians.   Nie ma Austriaków w Tyrolu Południowym?

    According to new apatite fission track, zircon- and apatite (U–Th)/He data, we constrain the near-surface history of the southeastern Tauern Window and adjacent Austrolapine units. The multi-system thermochronological data demonstrate that age-elevation correlations may lead to false implications about exhumation and cooling in the upper crust. We suggest that isothermal warping in the Penninic units that are in the position of a footwall, is due to uplift, erosion and the buildup of topography. Additionally we propose that exhumation rates in the Penninic units did not increase during the Middle Miocene, thus during the time of lateral extrusion. In contrast, exhumation rates of the Austroalpine hangingwall did increase from the Paleogene to the Neogene and the isotherms in this unit were not warped. The new zircon (U–Th)/He ages as well as zircon fission track ages from the literature document a Middle Miocene exhumation pulse which correlates with a period of enhanced sediment accumulation during that time. However, enhanced sedimentation- and exhumation rates at the Miocene/Pliocene boundary, as observed in the Western- and Central Alps, cannot be observed in the Eastern Alps. This contradicts a climatic trigger for surface uplift, and makes a tectonic trigger and/or deep-seated mechanism more obvious to explain surface uplift in the Eastern Alps. In combination with already published geochronological ages, our new data demonstrate Oligocene to Late Miocene fault activity along the Möll valley fault that constitutes a major shear zone in the Eastern Alps. In this context we suggest a geometrical and temporal relationship of the Katschberg-, Polinik–Möll valley- and Mur–Mürz faults that define the extruding wedge in the eastern part of the Eastern Alps. Equal deformation- and fission track cooling ages along the Katschberg–Brenner- and Simplon normal faults demonstrate overall Middle Miocene extension in the whole alpine arc. PMID:27065501

    Full Text Available The new problematic sponge Sarsteinia babai n. gen., n. sp. is described from the Kimmeridgian to Tithonian Plassen and Lärchberg Formations of the Northern Calcareous Alps of Austria. The type-locality is the Sarsteinalm north of Mount Hoher Sarstein in the Austrian Salzkammergut, other findings come from Mount Sandling, Mount Jainzen, Mount Trisselwand and the Litzlkogel-Gerhardstein-complex west of Lofer. Most findings can be attributed to a fore-reef to upper slope facies or slope-of-toe breccias, small fragments can occasionally also be found in the back-reef facies. The suprageneric systematic position of the new sponge is unknown so far since it shows morphological characteristics known from Inozoa but also from "stromatoporoids".

    The global climate is warming, which is leading to changes in the hydrological cycle. What are the impacts of these climatic changes on the occurrence and magnitude of extreme flood events? Are these changes simultaneous or independent? These are key questions for future flood-risk predictions. In Europe, regional climate models do not show robust results for the future occurrence of precipitation extremes, which is mainly due to the difficulty in resolving precipitation events and the limited temporal coverage of instrumental data. To overcome this issue, considerable effort has been put forward by the paleoclimate community to produce millennial-long flood proxy records from natural archives. This has led to a more comprehensive understanding of flood events in relation to climate variability. However, while there is an increased consensus in the long-term flood-temperature relationship, still very little is known about the role of precipitation changes on flood frequency and magnitude. This is largely due to the lack of long-term and high-quality precipitation records. Here we present a millennial-long precipitation reconstruction together with a flood-frequency record obtained from the same natural paleoclimate archive. This allows, for the first time, the direct comparison between the two climate variables in the Alps. We used the varved (annually laminated) sediments of proglacial Lake Oeschinen (1580 m a.s.l., NW European Alps) to reconstruct warm season (MJJA) precipitation and summer flood frequency back to AD 884. Our results support recent findings from an increasing number of studies in the Swiss, German, French and Austrian Alps showing that floods were consistently more frequent during cool periods over the last Millennium. While the relationship between flood frequency and inferred moist climate has remained speculative, our precipitation reconstruction allows for a direct comparison and shows that flood frequency also increased during wetter

    We present a method to quantify the number and value of buildings exposed to torrents and snow avalanches in the Austrian Alps, as well as the number of exposed people. Based on a unique population and building register dataset, a relational SQL database was developed that allows in combination with GIS data a rule-based nation-wide automated analysis. Furthermore, possibilities and challenges are discussed with respect to the use of such data in vulnerability assessment and with respect to resilience measures. We comprehensively address the challenge of data accuracy, scale and uncertainties. From the total of approximately 2.4 million buildings with a clearly attributable geographical location, around 120,000 are exposed to torrent processes (5 %) and snow avalanches (0.4 %); exposition was defined here as located within the digitally available hazard maps of the Austrian Torrent and Avalanche Control Service. Around 5 % of the population (360,000 out of 8.5 million inhabitants), based on those people being compulsory listed in the population register, are located in these areas. The analysis according to the building category resulted in 2.05 million residential buildings in Austria (85 %), 93,000 of which (4.5 %) are exposed to these hazards. In contrast, 37,300 buildings (1.6 %) throughout the country belong to the category of accommodation facilities, 5,600 of which are exposed (15 %). Out of the 140,500 commercial buildings, 8,000 (5 %) are exposed. A considerable spatial variation was detectable within the communities and Federal States. In general, an above-average exposition of buildings to torrent process and snow avalanches was detectable in communities located in the Federal State of Salzburg, Styria and Vorarlberg (torrents), and Tyrol and Vorarlberg (snow avalanches). In the alpine part of Austria, the share of exposed accommodation buildings was two times (Salzburg) and three times (Vorarlberg) higher than the regional average of exposed buildings

    This paper presents architecture of a lightning detector onboard future Austrian Lightning Nanosatellite (LiNSAT) in low-earth-orbit (LEO) and results of two terrestrial measurement campaigns to geo-locate and discriminate lightning types in presence of noise sources. The LiNSAT is proposed to be launched with three satellites constellation for the purpose of Time-of-Arrival technique. Our main scientific objective is to investigate lightning events by the observation of VHF electromagnetic signals (Sferics) and to derive the signatures of lightning. One of the important parameters is lightning flash rate, which can be used as a proxy for locating severe weather activity. Another objective is to discriminate the discharges of lightning events evaluated by the inherent features and to differentiate cloud discharges (IC; intercloud and Intracloud) from ground discharges (CG; cloud-to-ground), return strokes, leaders and transionospheric pulse pairs. The discrimination is important because the ratio of the two (IC/CG) is a good indicator of convective storm development. We conducted two measurement campaigns; one for artificial lightning produced in high voltage chamber and second natural lightning recorded at urban environment. We focus mainly on envelopes of the received time series including noisy features and narrowband carriers to extract characteristic parameters. We determined the chamber inter-walls distance by considering reflections in the first measurements. Initially the algorithm for the instruments onboard electronics has been developed and verified in Matlab and will be transformed to machine language. Next consideration is to use existing lightning data from previous French mission “DEMETER” to validate the accomplished results. The lightning detector onboard has to perform tasks like determination of pulse-width, pulse-count, pulse rise/fall time etc; we get noise possibly from narrowband carriers and artifacts from satellite itself (EMC) in

    Full Text Available Abstract The period 1995 to 1999 did not yield any confirmed lynx data in the German part of the Alpine Arc. Only from the area of Berchtesgaden, 6 Q3-data exist. Outside of the Alpine arc Germany hosts some areas with lynx evidence. For a better understanding of the real situation in the Alps it would be necessary to have a few skilled persons who could check any lynx signs quickly and/or interview people that suspect lynx presence. Because of possible lynx immigrations, especially from eastern Switzerland, and its central location, it would be important that Germany starts to play a more active role in lynx conservation in the Alps. Conservation strategies and possible actions need to be assessed in the near future.

    The region of the Central and Eastern Europe is an area characterised by a relatively high seismicity. The active seismogenic structures and the related potentially destructive events are located in the proximity of the political boundaries between several countries existing in the area. An example is the seismic region between the NE Italy (FVG, Trentino-Alto Adige and Veneto), Austria (Tyrol, Carinthia) and Slovenia. So when a destructive earthquake occurs in the area, all the three countries are involved. In the year 2001 the Agencija Republike Slovenije za Okolje (ARSO) in Slovenia, the Department of Mathematics and Geoscience of the University of Trieste (DMG), the OGS (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale) in Italy and the Zentralanstalt für Meteorologie und Geodynamik (ZAMG) in Austria signed an agreement for the real-time seismological data exchange in the Southeastern Alps region. Soon after the Interreg IIIa Italia-Austria projects "Trans-National Seismological Networks in the South-Eastern Alps" and "FASTLINK" started. The main goal of these projects was the creation of a transfrontier network for the common seismic monitoring of the region for scientific and civil defense purposes. During these years the high quality data recorded by the transfrontier network has been used, by the involved institutions, for their scientific research, for institutional activities and for the civil defense services. Several common international projects have been realized with success. The instrumentation has been continuously upgraded, the installations quality improved as well as the data transmission efficiency. In the 2013 ARSO, DMG, OGS and ZAMG decided to name the cooperative network "Central and Eastern European Earthquake Research Network - CE3RN". The national/regional seismic networks actually involved in the CE3RN network are: • Austrian national BB network (ZAMG - OE) • Friuli Veneto SP network (OGS - FV) • Friuli VG

    2009-01-01

    The two objectives of this paper are to describe a steady-state version of the Age-Layered Population Structure (ALPS) Evolutionary Algorithm (EA) and to compare it against other GAs on real-valued problems. Motivation for this work comes from our previous success in demonstrating that a generational version of ALPS greatly improves search performance on a Genetic Programming problem. In making steady-state ALPS some modifications were made to the method for calculating age and the method for moving individuals up layers. To demonstrate that ALPS works well on real-valued problems we compare it against CMA-ES and Differential Evolution (DE) on five challenging, real-valued functions and on one real-world problem. While CMA-ES and DE outperform ALPS on the two unimodal test functions, ALPS is much better on the three multimodal test problems and on the real-world problem. Further examination shows that, unlike the other GAs, ALPS maintains a genotypically diverse population throughout the entire search process. These findings strongly suggest that the ALPS paradigm is better able to avoid premature convergence then the other GAs.

  14. Lynx distribution in the French Alps (1995-1999

    2001-12-01

    Full Text Available Abstract From 1995 to 1999, 69 data were recorded on lynx presence in the French Alps, in an area of 3,636 km². Lynx presence was recorded in the major forested regions of the pré-Alpes (Chablais, Glière/Aravis, Bauges, Chartreuse, Vercors, Diois/Beauchène, in the Chamonix and Maurienne valleys and the Briançon region, but no large continuous area of presence was shown. Lynx have probably been permanently present in certain locations during the past years, but the presence of a large lynx population in the Alps is improbable in the northern French Alps. In the future, we recommend that habitat suitability for lynx in the northern French-Alps should be assessed, together with possibilities of connection between alpine regions and possible bias in the monitoring system.

Quelles spatialités et quelles territorialités travaillent les populations alpines aujourd’hui ? Quelles sont les figures contemporaines de la circulation et des flux, et les figures complémentaires de l’ancrage et de la refondation territoriale ? Voici les questions que cet essai se propose de développer. Ce texte reprend le contenu d’une conférence donnée dans le cadre de la célébration du centenaire de l’Institut de Géographie Alpine.

  2. Autochthonous Linguistic Minorities in the Italian Alps:

    2011-08-01

    Full Text Available More than any other area in Western Europe, the Alps, especially the Italian Alps, are home to great ethno-cultural diversity: there, no less than seven autochthonous linguistic minorities coexist side by side with the respective official majority. Now being considered an important cultural heritage by the state as well as by the regions, new legislation offers protection to all ‘linguistic-historic minorities’ in Italy. Our study shows, however, that it is quite difficult to maintain such groups, since it is largely unknown where exactly the minority areas are situated. Based on that, local actor groups in various communities take advantage of this lack of knowledge and declare themselves minority territories although they show no linguistic varieties. An important objective of this project is therefore to present a cartographic representation of this linguistic diversity. Subsequently, the contribution discusses case studies of distinct ethno-linguistic self-awareness. Even though with Law No. 482 a first important step was taken to preserve the linguistic minorities, their progressive decline by territorial and numerical criteria cannot be denied. Today, besides unfavorable bio-demographic factors and “diffuse ethnicity,” other causes are current demographic processes. In this framework the amenity migrants, those new immigrants who have discovered the mountains as a new, desirable settlement space, play a decisive role by reinforcing the assimilation process.Les Alpes, plus précisément les Alpes italiennes, plus que toute autre région d'Europe Occidentale, sont un lieu de grande diversité ethnoculturelle : pas moins de sept minorités linguistiques autochtones y coexistent, côte à côte avec la majorité officielle correspondante. Maintenant considérées comme un héritage culturel important par les états ainsi que par les régions, une nouvelle législation offre une protection à toutes les « minorités linguistiques

    Axion-like particles have good theoretical motivation and are characterized by conversion to photons in astrophysical magnetic fields. Galaxy clusters are the most efficient convertors of axion-like particles to photons in the universe. I discuss the physics and phenomenology of ALPs, and describe their astrophysical implications, with particular reference to the recently observed 3.5 keV X-ray line that is a candidate for a dark matter decay line. I discuss interpretations of this line in terms of dark matter decaying to an axion-like particle, that then converts to a photon in cluster magnetic fields, and describe the compatibility of this scenario with data and the different phenomenology for cool-core and non-cool-core clusters.

    The understanding of the subduction-related processes benefited by the studies of the high-pressure (HP) meta-morphic rocks from the western Alps. The most stimu-lating information was obtained from the inner part of the western Alpine belt, where most tectonic units show an early Alpine eclogite-facies recrystallisation. This is especially true for the Austroalpine Sesia Zone and the Penninic Dora-Maira massif. From the Sesia zone,which consists of a wide spectrum of continental crust lithologies recrystallised to quartz-eclogite-facies min-eral assemblages, the first finding of a jadeite-bearingmeta-granitoid has been described, supporting evidencethat even continental crust may subduct into the mantle.From the Dora-Maira massif the first occurrence of regional metamorphic coesite has been reported, open-ing the new fertile field of the ultrahigh-pressure meta-morphism (UHPM), which is now becoming the rule in the collisional orogenic belts.

    10Be dating of prominent glacier advances (stadials) in the Alps supports the correlation of the Gschnitz stadial (> 15.4 ka) with the Heinrich 1 ice rafting event (Greenland Stadial 2a), the Egesen-maximum advance (˜ 12.3-12.4 ka) with the early Younger Dryas (Greenland Stadial 1), the Kartell advance (˜ 10.8 ka) with the Preboreal Oscillation and the Kromer advance (˜ 8.4 ka) with the Central European cold phase 3. The interpretation of the glacial record with glacier-climate models in terms of summer temperature change (ΔTs) and precipitation change (Δ P) shows that climate during the Gschnitz stadial was ˜ 10 K colder than at present and precipitation was reduced to ˜ 25% of modern annual sums with a possible tendency towards slightly more humid conditions in the southeastern Alps. During the early Younger Dryas, Δ P depends on the estimated ΔTs. For a ΔTs of - 3.5 K, Δ P along the northern fringe of the Eastern Alps was about 0 to + 15%, in the central valleys Δ P was in the order of - 20 to - 30%. A scenario with a ΔTs of - 5 K leads to generally drier conditions (˜ - 15% vs. ˜ - 50% Δ P) but the spatial pattern of precipitation change remains the same. The Kromer advance was possibly characterised by more humid conditions than today along the northern fringe of the Eastern Alps. In the valleys of the Central Alps, precipitation seems to have been similar to modern values. Methodologically, simple empirical relationships between summer temperature and precipitation at the equilibrium line altitude yield similar results as an analytical glacial-meteorological model. However, the analytical model allows a more detailed analysis of the climatic parameters influencing glacier behaviour. In the case of the Egesen-maximum and Kromer advances, the accuracy of Δ P depends on the reliability of ΔTs, which is derived from timberline depression and on the dating control. In the case of the Gschnitz stadial, the accuracy of ΔTs depends mainly on the

    The impact of glaciations on the topography of the Alps is still unclear: Long-term denudation rate determined by low-T thermochronology are in the range of 0.2 to 1 mm/yr, and increased during the Plio-Quaternary by ~3 fold (Vernon et al., 2008). Such an increase is also documented by peri-alpine sediment budget (Kuhleman, 2000), with a two to three fold increase in sediment yields since 5-3 Ma. This increase was considered as evidence of a climatically-driven surface process change, a large component of which was attributed to increased precipitation (Cederbom et al., 2004) and erosion by glacial processes (Champagnac et al., 2007). The transition from full fluvial to glaciated landscape must have involved major changes in topography and erosion rates, in particular given the changes in sediment yield (Kuhlemann, 2000; Mutoni et al 2003). However, the timing of the onset of intense glacial erosion as well as its rates are still ambiguous. The glacial erosion seems to have accelerated around 0.9 Ma as suggested by the ten fold increase of incision rates of a valley in the Central Alps (Häuselmann et al., 2007), and by information about vegetation and sedimentologic changes (Muttoni et al., 2003; Scardia et al., 2006). There is however no direct quantification of topographic change during the Plio-Quaternary. We present here how we use OSL-thermochronology, a new thermochronometer of exceptionally low closure temperature (about 30-400 C) (Herman et al subm.) and a glacial erosion model (Herman and Braun 2008) to estimate topographic changes in the Alps in response to glaciations. Because of its low closure temperature, OSL-thermochronology enables quantification of events of less than 1 Ma at very small wavelength of the topography. We collected two vertical profiles, one in the Zermatt Valley (Valais) and one in Maurienne Valley (Savoy). We infer from these results changes in topography, date and quantify relief creation under glacial - interglacial cycles

    Autoimmune lymphoproliferative syndrome (ALPS) is a disorder of abnormal lymphocyte survival caused by defective Fas-mediated apoptosis, leading to lymphadenopathy, hepatosplenomegaly, and an increased number of double-negative T cells (DNTs). Treatment options for patients with ALPS are limited. Rapamycin has been shown to induce apoptosis in normal and malignant lymphocytes. Since ALPS is caused by defective lymphocyte apoptosis, we hypothesized that rapamycin would be effective in treating ALPS. We tested this hypothesis using rapamycin in murine models of ALPS. We followed treatment response with serial assessment of DNTs by flow cytometry in blood and lymphoid tissue, by serial monitoring of lymph node and spleen size with ultrasonography, and by enzyme-linked immunosorbent assay (ELISA) for anti-double-stranded DNA (dsDNA) antibodies. Three-dimensional ultrasound measurements in the mice correlated to actual tissue measurements at death (r = .9648). We found a dramatic and statistically significant decrease in DNTs, lymphadenopathy, splenomegaly, and autoantibodies after only 4 weeks when comparing rapamycin-treated mice with controls. Rapamycin induced apoptosis through the intrinsic mitochondrial pathway. We compared rapamycin to mycophenolate mofetil, a second-line agent used to treat ALPS, and found rapamycin's control of lymphoproliferation was superior. We conclude that rapamycin is an effective treatment for murine ALPS and should be explored as treatment for affected humans.

    Autoimmune lymphoproliferative syndrome (ALPS) is an uncommon nonmalignant lymphoproliferative disease which is characterized by chronic, persistent or recurrent lymphadenopathy, splenomegaly, hepatomegaly, immune cytopenia , hypergammaglobinemia and increased risk of lymphoma. We report a 2-year old boy with hepatosplenomegaly as first presentation. Petechial and purpuric rashes with massive cervical lymphadenopathies developed 10 months later.In laboratory tests anemia, thrombocytopenia and hypergammaglobinemia were observed. According to flocytometry increased double negative T cells and by apoptosis assay decrease apoptosis of lymphocytes accompanied clinical manifestations, thus diagnosis of ALPS was established. In conclusion; in all patients with massive lymphadenopathy and hepatosplenomegay; especially with cytopenia; ALPS should be considered.

    A small collection of echinoderm holdfasts from the Ludlow Cardiola Formation of the Carnic Alps (Austria) contains a wide range of morphologies as a response of environmental adaptation. In general, the holdfasts have a globous and massive dome-like profile with several processes arranged in a sub-radial disposition, so to create a sort of ‘star-like’ outline. A small central depression is common but not present on all specimens. The distinctive holdfasts are preserved in an iron-rich phase, documenting a substitution that has also affected other non-echinoderm calcareous material. (Author)

    Magnetic fields in extragalactic space between galaxy clusters may induce conversions between photons and axion-like particles (ALPs), thereby shielding the photons from absorption on the extragalactic background light. For TeV gamma rays, the oscillation length (losc) of the photon-ALP system becomes inevitably of the same order as the coherence length of the magnetic field l and the length over which the field changes significantly (transition length lt) due to refraction on background photons. We derive exact statistical evolution equations for the mean and variance of the photon and ALP transfer functions in the non-adiabatic regime (losc ~ l gg lt). We also make analytical predictions for the transfer functions in the quasi-adiabatic regime (losc ll l, lt). Our results are important in light of the upcoming Cherenkov Telescope Array (CTA), and may also be applied to models with non-zero ALP masses.

  13. The lynx in the Italian South-Eastern Alps

    1998-09-01

    Full Text Available Abstract From 1986 to May 1995 I collected records of signs of lynx presence in the region of Friuli Venezia Giulia. A series of regularly checked trail transects, explorative excursions, and the collection of second-hand observations led to a total of 150 records. They confirm lynx presence and allow an assessment of the situation. The first lynx are believed to have immigrated to the northern part of the study area from Austria. An increase and the distribution in the signs of presence show a south-westerly expansion. The trend in the Julian Alps and Pre-Alps is also increasing. Some interpretations of the status of this new population are made. The study area is in the far south-eastern Alps. This area is important as a corridor between the Alps and the Balkans, where a reintroduced lynx population exists which would be able to support the Alpine lynx population through dispersing lynx.

    the Ligurian Sea during the Early-Middle Miocene and to compression/rotation of the Adriatic indenter inducing lateral extrusion. Interactions between the different geodynamic processes control the balance between intrinsic and extrinsic dynamics and explain the late tectonic evolution of the belt (Sue et al., 2007). Numerous geodynamic agents are involved in the Neogene to present evolution of the Western and Central Alps, including boundary conditions (collision, rotation, free boundaries), deep dynamics (gravitational forces, slab dynamics, vertical indentation), and surface processes (erosion, transfert, post-glacial rebound). Three main processes seem to play a fundamental role in the tectonic evolution from orogen-parallel to orogen-perpendicular extension. First, the end of the opening of the Ligurian Sea during Late Miocene times would imply a decrease in orogen-parallel extension. Second, a progressive decrease in the rate of continental collision (Europe-Adria) appears to be critical for the change of tectonic regime. The decrease of convergence rates allows buoyancy forces to develop, and to control gravitational spreading. Third, the Plio-Quaternary increase of erosion implies major mass transfert from inside to outside of the belt and may have deeply changed the alpine tectonics, vertical motions, and denudation structure of the alpine realm (Willett et al., 2006; Champagnac et al., 2007; Vernon et al., 2008).

    2006-01-01

    Full Text Available The effects of the climate characters and climate index calculated by Thornthwaite-Mather method on diameter increment of Austrian pine trees in the seedling seed orchard on Jelova Gora was studied in the period from 1996 to 2002. The samples for dendrometric analysis were taken from 498 trees in 40 half-sib lines originating from the best natural sites of this species. A strong correlation was determined between the range of precipitation regime and Thornthwaite-Mather climate index, and the development of current diameter increment. The study results indicate that the diameter increment of Austrian pine increases considerably with the increase of humidity, regardless of the relatively modest demands regarding the site productive characteristics.

    2006-01-01

    Full Text Available The aim of this paper is to syntetize theory of entrepreneurship of the Austrian School of economics with the contractual theory of the firm. Transaction cost theory of Ronald Coase and his followers holds that the firm is the organization with dominant component of ordering, while market is defined by competition and rivalry. But, market also includes interdependency and cooperation, such as in the case of cartel. Therefore non-competitive forms of economic coordination are not specificity for the firm, and can be observed in the open market as well. Agency theory rejects the notion of the firm as a hierarchy, and it is based on completeness of knowledge and contract. Theory of entrepreneurship and monetary calculation of Austrian School enables us to integrate contractual theory into the theoretical setting characterized by uncertainty, information asymmetry and positive transaction costs.

    Several writers link entrepreneurship to asset ownership, trying to incorporatethe theory of entrepreneurship into the theory of the firm. The critical link, weargue, is capital heterogeneity. Transaction cost, property rights, and resourcebasedapproaches to the firm assume that assets, both...... tangible and intangible,are heterogeneous; arranging these assets to minimize contractual hazards, toprovide efficient investment incentives, or to exploit competitive advantage isconceived as the prime task of economic organization. None of these approaches,however, is based on a systematic theory...... of capital heterogeneity. Inthis paper we outline the approach to capital developed by the Austrian schoolof economics and integrate it into an entrepreneurial theory of the firm. We refineAustrian capital theory by defining capital heterogeneity in terms of subjectivelyperceived attributes, that is...

The introduction is devoted to the development of Hauzmajstor, a small real estate maintenance firm, founded by a Serbian repatriate in 2004. Beginning with its start up as the first daughter firm of Komon sens, a consulting and project development firm, the study follows its adaptation to the local business environment, concentrating on its organizational and business culture. The focus of the study is on the detailed description and analysis of experiences of the Hauzmajstor insiders with the Austrian Rustler, first as a potential, and later as an actual partner. In the end, a view from the other side, i.e. perceptions of Hauzmajstor by the Rustler Group area manager are given.

  3. Constraining ALP-photon coupling using galaxy clusters

    CERN Document Server

    Schlederer, Martin

    2015-01-01

    In this study, we propose a new approach to constrain the coupling of axion-like particles (ALPs) to photons. One intriguing property of these ALPs is their mixing with photons within magnetic fields. This mixing allows photons propagating in magnetic fields to convert into ALPs and \\textit{vice versa}. Plasma effects can lead to resonant conversion, further enhancing the conversion probability. For suitable ALP masses, this resonant conversion can occur for cosmic microwave background photons transversing galaxy clusters which would distort the CMB spectrum in the direction of galaxy clusters. We compare the predicted distortion with recent measurements of the thermal Sunyaev-Zeldovich Compton parameter to obtain upper limits on the coupling between photons and ALPs. The constraints apply to the mass range of approximately $2\\cdot 10^{-14}$ eV $ \\lesssim m_\\phi \\lesssim 3\\cdot 10^{-12}$ eV in which resonant photon-ALP conversions can occur. Using simple galaxy cluster models, we obtain new limits for this ma...

    Austrian field cases of canine distemper (14 dogs, one badger [Meles meles] and one stone marten [Martes foina]) from 2002 to 2007 were investigated and the case histories were summarised briefly. Phylogenetic analysis of fusion (F) and haemagglutinin (H) gene sequences revealed different canine distemper virus (CDV) lineages circulating in Austria. The majority of CDV strains detected from 2002 to 2004 were well embedded in the European lineage. One Austrian canine sample detected in 2003, with a high similarity to Hungarian sequences from 2005 to 2006, could be assigned to the Arctic group (phocine distemper virus type 2-like). The two canine sequences from 2007 formed a clearly distinct group flanked by sequences detected previously in China and the USA on an intermediate position between the European wildlife and the Asia-1 cluster. The Austrian wildlife strains (2006 and 2007) could be assigned to the European wildlife group and were most closely related to, yet clearly different from, the 2007 canine samples. To elucidate the epidemiological role of Austrian wildlife in the transmission of the disease to dogs and vice versa, H protein residues related to receptor and host specificity (residues 530 and 549) were analysed. All samples showed the amino acids expected for their host of origin, with the exception of a canine sequence from 2007, which had an intermediate position between wildlife and canine viral strains. In the period investigated, canine strains circulating in Austria could be assigned to four different lineages reflecting both a high diversity and probably different origins of virus introduction to Austria in different years.

    When Austria joined the Geneva Convention the "Patriotischer Hilfsverein" (Patriotic Aid Society) which was founded for the concerns of wounded soldiers, was named "Austrian Society of the Red Cross". It had to stand its first big test in 1912 in the first Balkan war; military surgeons and bacteriologists were deployed to all warring states. The cholera dominated under the infectious diseases among the various forces and the civilian populations. Upon request of the Bulgarian king renowned bacteriologists of the University of Vienna were dispatched. Their work presented the first action of bacteriology for disease control on theatres of war. The great success of the surgical and hygienic measures initiated in 1912 a reform of the Austrian Red Cross. In 1913 Austria made a detailed application to the International Committee of the Red Cross in order to extend the Geneva Convention to war epidemics. The Committee forwarded and recommended this application to all member states, however, the outbreak of the First World War then prevented its resolution.

    Renal denervation (RDN) is a new procedure for treatment-resistant hypertensive patients. In order to monitor all procedures undergone in Austria, the Austrian Society of Hypertension established the investigator-initiated Austrian Transcatheter Renal Denervation (TREND) Registry. From April 2011 to September 2014, 407 procedures in 14 Austrian centres were recorded. At baseline, office and mean 24-h ambulatory blood pressure (ABP) were 171/94 and 151/89 mmHg, respectively, and patients were taking a median of 4 antihypertensive medications. Mean 24-h ABP changes after 2–6 weeks, 3, 6 and 12 months were -11/-6, -8/-4, -8/-5 and -10/-6 mmHg (p<0.05 at all measurements), respectively. The periprocedural complication rate was 2.5%. Incidence of long-term complications during follow-up (median 1 year) was 0.5%. Office BP and ABP responses showed only a weak correlation (Pearson coefficient 0.303). Based on the data from the TREND registry, ambulatory blood pressure monitoring in addition to office BP should be used for patient selection as well as for monitoring response to RDN. Furthermore, criteria for optimal patient selection are suggested. PMID:27529426

  11. Searching for axions and ALPs from string theory

    2012-09-15

    We review searches for closed string axions and axion-like particles (ALPs) in IIB string flux compactifications. For natural values of the background fluxes and TeV scale gravitino mass, the moduli stabilisation mechanism of the LARGE Volume Scenario predicts the existence of a QCD axion candidate with intermediate scale decay constant, f{sub a} {proportional_to}10{sup 9/12} GeV, associated with the small cycles wrapped by the branes hosting the visible sector, plus a nearly massless and nearly decoupled ALP associated with the LARGE cycle. In setups where the visible sector branes are wrapping more than the minimum number of two intersecting cycles, there are more ALPs which have approximately the same decay constant and coupling to the photon as the QCD axion candidate, but which are exponentially lighter. There are exciting phenomenological opportunities to search for these axions and ALPs in the near future. For f{sub a} {proportional_to}10{sup 11/12} GeV, the QCD axion can be the dominant part of dark matter and be detected in haloscopes exploiting microwave cavities. For f{sub a} {proportional_to}10{sup 9/10} GeV, the additional ALPs could explain astrophysical anomalies and be searched for in the upcoming generation of helioscopes and light-shining-through-a-wall experiments.

    1998-09-01

    Full Text Available Abstract The lynx (Lynx lynx had been eradicated in the German Alps by the middle of the 19th century. Since the early 1970s there have been several attempts to initiate the re-introduction of lynx into the German Alps, but none of the projects could be carried out because of the still very controversial attitudes towards the species, and because of competition between institutions. Natural re-colonization of the German Alps by lynx can be expected sooner or later from Switzerland or Austria. Although lynx are already present in some parts of Germany outside the Alps, neither an organized monitoring system nor compensation regulations for losses of livestock exist. For a successful comeback of lynx into Germany, including the German Alps, more efforts than a year-round protection by the federal hunting law is needed. Initiative management actions and intensive public education are necessary to obtain and secure public acceptance of the lynx.

    2010-01-01

    Autoimmune lymphoproliferative syndrome (ALPS) is a disorder of T cell dysregulation caused by defective Fas-mediated apoptosis. Patients with ALPS can develop a myriad of clinical manifestations including lymphadenopathy, hepatosplenomegaly, autoimmunity and increased rates of malignancy. ALPS may be more common that originally thought, and testing for ALPS should be considered in patients with unexplained lymphadenopathy, hepatosplenomegaly, and/or autoimmunity. As the pathophysiology of ALPS is better characterized, a number of targeted therapies are in preclinical development and clinical trials with promising early results. This review describes the clinical and laboratory manifestations found in ALPS patients, as well as the molecular basis for the disease and new advances in treatment.

    ALPS II is a light shining through a wall style experiment that will use the principle of resonant enhancement to boost the conversion and reconversion probabilities of photons to relativistic WISPs. This will require the use of long baseline low-loss optical cavities. Very high power build up factors in the cavities must be achieved in order to reach the design sensitivity of ALPS II. This necessitates a number of different sophisticated optical and control systems to maintain the resonance and ensure maximal coupling between the laser and the cavity. In this paper we report on the results of the characterization of these optical systems with a 20 m cavity and discuss the results in the context of ALPS II.

  17. Fission track ages and Exhumation mechanisms of the Tauern Window, Eastern Alps

    The Tauern Window (TW) is a thermal and structural dome which exposes Penninic basement, its cover units as well as parts of the overlying Austroalpine basement in the central part of the Eastern Alps. The peak of metamorphism was attained approximately at 30Ma (Selverstone et .al, 1992), followed by cooling and exhumation throughout Miocene time. Most of the tertiary exhumation of the Eastern Alps was localized in the TW, from Early Oligocene to late Miocene time. A current debate centers on the exhumation mechanisms of Penninic rocks in the core of the TW, namely to assess whether orogen-parallel extension (e.g., Selverstone, 1988) or a combination of folding and erosion (eg., Rosenberg et al., 2004) with subordinate extension were the controlling processes. E-W extension is well documented at the western (Brenner Fault) and eastern (Katschberg Fault) margins of the window (e.g., Behrmann, 1988; Selverstone, 1988; Genser and Neubauer, 1989). In contrast, upright folding dominates the internal structure of the dome, and in particular along its western part, where fold amplitudes, mostly eroded during folding, attained up to 10 km. This study attempts to assess the relative importance of folding and erosion and of orogen-parallel extension during exhumation by analyzing the spatial and temporal cooling patterns of apatite and zircon fission track ages. The compilation of published apatite and zircon fission track ages indicates a concentric younging of both the apatite and zircon ages toward the core of the TW. The concentric isochrones follow the map trace of the axial planes of the upright folds of the western and eastern TW. This cooling pattern is in contrast to the one expected by a process of extensional unroofing, which in map view would results in isochrons parallel to the extensional faults and progressively younging towards them (e.g., Foster et al., 2001). We therefore propose that folding and erosion were primarily responsible for exhuming the Penninic

    The Southern Alps orogen of New Zealand results from late Cenozoic convergence between the Indo-Australian and Pacific plates and is one of the most active mountain belts in the world. Metamorphic rocks carrying a polymetamorphic legacy, ranging from low-greenschist to high-grade amphibolites, are exhumed in the hanging wall of the Alpine Fault. On a regional scale, the metamorphic grade has previously been described in terms of metamorphic zones and mineral isograds; application of quantitative petrology being severely limited owing to unfavorable quartzofeldspathic lithologies. This study quantifies peak metamorphic temperatures (T) in a 300 × 20 km area, based on samples forming 13 transects along-strike from Haast in the south to Hokitika in the north, using thermometry based on Raman spectroscopy of carbonaceous material (RSCM). Peak metamorphic T decreases across each transect from ≥ 640 °C locally in the direct vicinity of the Alpine Fault to less than 330 °C at the drainage divide 15-20 km southeast of the fault. Thermal field gradients exhibit a degree of similarity from the southernmost to the northernmost transects, are greater in low-grade semischist than high-grade schist, are affected by folding or discontinuous juxtaposition of metamorphic zones, and contain limited information on crustal-scale geothermal gradients. Temperatures derived by RSCM thermometry are slightly (≤ 50 °C) higher than those derived by traditional quantitative petrology using garnet-biotite thermometry and THERMOCALC modeling. The age of RSCM T appears to be mostly pre-Cenozoic over most of the area except in central Southern Alps (Franz Josef-Fox area), where the amphibolite facies schists have T of likely Cenozoic age. The RSCM T data place some constraints on the mode of exhumation along the Alpine Fault and have implications for models of Southern Alps tectonics.

    Indentation of rigid blocks into rheologically weak orogens is generally associated with spatiotemporally variable vertical and lateral block extrusion. The European Eastern and Southern Alps are a prime example of microplate indentation, where most of the deformation was accommodated north of the crustal indenter within the Tauern Window. However, outside of this window only the broad late-stage exhumation pattern of the indented units as well as of the indenter itself is known. In this study we refine the exhumational pattern with new (U-Th-Sm)/He and fission-track thermochronology data on apatite from the Karawanken Mountains adjacent to the eastern Periadriatic fault and from the central-eastern Southern Alps. Apatite (U-Th-Sm)/He ages from the Karawanken Mountains range between 12 and 5 Ma and indicate an episode of fault-related exhumation leading to the formation of a positive flower structure and an associated peripheral foreland basin. In the Southern Alps, apatite (U-Th-Sm)/He and fission-track data combined with previous data also indicate a pulse of mainly Late Miocene exhumation, which was maximized along thrust systems, with highly differential amounts of displacement along individual structures. Our data contribute to mounting evidence for widespread Late Miocene tectonic activity, which followed a phase of major exhumation during strain localization in the Tauern Window. We attribute this exhumational phase and more distributed deformation during Adriatic indentation to a major change in boundary conditions operating on the orogen, likely due to a shift from a decoupled to a coupled system, possibly enhanced by a shift in convergence direction.

  20. A new observation of ALPs-photon coupling

    One of the fundamental results used in observational cosmology is the distance duality relation (DDR), which relates the luminosity distance, $D_L$, with angular diameter distance, $D_A$, at a given redshift $z$. We suggest to employ the observed limits of this relation to constrain the coupling of axion like particles (ALPs) with photons. With available data we are able to provide improved mixing limit. The method can provide very stringent constraint on ALPs mixing with future improved DDR observations. Also any deviation in DDR can be conventionally explained as photons decaying to axions or vice-versa.

    The Atominstitute of the Austrian Universities has conducted various space research missions in the last 12 years in cooperation with the Institute for Biomedical Problems in Moscow. They dealt with the exact determination of the radiation hazards for cosmonauts and the development of precise measurement devices. Special emphasis will be laid on the last experiment on space station MIR the goal of which was the determination of the depth distribution of absorbed dose and dose equivalent in a water filled Phantom. The first results from dose measurements onboard the International Space Station (ISS) will also be discussed. The spherical Phantom with a diameter of 35 cm was developed at the Institute for Biomedical Problems and had 4 channels where dosimeters can be exposed in different depths. The exposure period covered the timeframe from May 1997 to February 1999. Thermoluminescent dosimeters (TLDs) were exposed inside the Phantom, either parallel or perpendicular to the hull of the spacecraft. For the evaluation of the linear energy transfer (LET), the high temperature ratio (HTR) method was applied. Based on this method a mean quality factor and, subsequently, the dose equivalent is calculated according to the Q(LET infinity) relationship proposed in ICRP 26. An increased contribution of neutrons could be detected inside the Phantom. However the total dose equivalent did not increase over the depth of the Phantom. As the first Austrian measurements on the ISS dosimeter packages were exposed for 248 days, starting in February 2001 at six different locations onboard the ISS. The Austrian dosimeter sets for this first exposure on the ISS contained five different kinds of passive thermoluminescent dosimeters. First results showed a position dependent absorbed dose rate at the ISS.

    This pilot study aimed to investigate feasibility, acceptance, and effects of biofeedback-assisted mental training in a population of fifteen 10-year-old pupils in an Austrian elementary school. Participants were instructed in relaxation techniques by using biofeedback. Before intervention, after 6 weeks with active mental training and with regular instructions by the teacher, and after a further time period of 6 weeks without instructions, attention and concentration improved. The results indicate feasibility, good acceptance, and beneficial effects of biofeedback-assisted mental techniques in Austrian elementary school pupils.

    We describe the first reported case of Austrian's syndrome in an injecting drug user (IDU). The triad of endocarditis, meningitis and pneumonia caused by invasive pneumococcal disease (IPD) is most commonly associated with excess alcohol. Injecting drug use is a recognised risk factor for IPD, whose prevalence and resistance continue to rise. We propose that injecting drug use is associated with Austrian's syndrome and that it should at least be considered in 'at risk' groups presenting with IPD. Furthermore, IDU presenting with IPD, meningitis and pneumonia should be considered for echocardiography.

    move south while the overriding Adriatic plate shifted north. In conclusion, a rollback mechanism yields an orogeny/foreland basin ensemble where subsidence and thrusting are partly decoupled at the scale of the orogeny. These mechanisms explain the formation of the Alps through the delamination and accretion of crustal rocks from the subducting plate, yielding in the stacking of Alpine nappes. Such a model is capable of reconciling previously conflicting stratigraphic, palaeotopographic, seismic and plate tectonic observations in the Central Alps and the Molasse Basin (Schlunegger and Kissing, 2015).

    Soil is an essential, non-renewable resource, which fundamentally needs sustainable management. Soils in mountain regions like the Alps have a diverse small-scale distribution and they are characterized by a slow soil development and multilayer profiles. This is mainly caused by high process dynamics and harsh climate conditions. Therefore, soils are particularly vulnerable and require a sustainable management approach. Furthermore, the global change, especially the climate and land use change, leads to new demands on the soil. Thus, high-resolution spatial informations on soil properties are required to protect this resource and to consider its properties in spatial planning and decision making. In the Alpine region soil maps are mostly confined to small (mostly agriculture) areas. Especially, in higher altitudes of the Alps pedologic research and data collection are lacking. However, nowadays and in the future systematic soil mapping works are and will be no longer applied. Another methodical problem arises because each Alpine country has its own national soil mapping and classification system which are not adapted to Alpine areas. Therefore, appropriate methods of working practices for the Alpine region are mostly missing. The central aim of the research project "ReBo - Terrain Classification based on airborne laser scanning data to support soil mapping in the Alps", founded by the Autonomous Province of Bolzano - South Tyrol, is to develop and verify a concept, which allows the collection of soil data through an optimized interaction of soil mapping and geomorphometric analysis. The test sites are located in South Tyrol (Italy). The workflow shall minimise the required pedologic field work and shall provide a reliable strategy for transferring punctual soil informations into spatial soil maps. However, for a detailed analysis a systematic pedologic field work is still indispensable. As in the Alps reliable soil mapping and classification standards are lacking

  8. Vulnerability from a co-evolutionary perspective: valuating natural hazards management in the Eastern Alps

    Thaler, Thomas; Fuchs, Sven

    2014-05-01

    In past decades, we observed a change in natural hazard management from a structural, security-based policy towards an integrated, risk-based management system. Therefore, the concept of vulnerability has become central in the policy debate. In order to assess vulnerability, we need a broader understanding of the term to manage natural hazards and to reduce damages and losses from future events. This paper adopts a co-evolutionary perspective to provide a critical assessment of vulnerability in natural hazard management, taking the Eastern Alps as an example. We discuss the structural, social and institutional vulnerability and governance from an integrated point of view to understand and to analyse the interdependences and interactions between human and physical systems. The aim is to consider the dynamic interactions between multiple conceptualised vulnerabilities in evaluating natural hazard management systems. A co-evolutionary framework widens the explanatory of multiple interactions in vulnerability to provide useful information and concepts to improve risk management.

    The Airborne Lidar Processing System (ALPS) analyzes Experimental Advanced Airborne Research Lidar (EAARL) data—digitized laser-return waveforms, position, and attitude data—to derive point clouds of target surfaces. A full-waveform airborne lidar system, the EAARL seamlessly and simultaneously collects mixed environment data, including submerged, sub-aerial bare earth, and vegetation-covered topographies.ALPS uses three waveform target-detection algorithms to determine target positions within a given waveform: centroid analysis, leading edge detection, and bottom detection using water-column backscatter modeling. The centroid analysis algorithm detects opaque hard surfaces. The leading edge algorithm detects topography beneath vegetation and shallow, submerged topography. The bottom detection algorithm uses water-column backscatter modeling for deeper submerged topography in turbid water.The report describes slant range calculations and explains how ALPS uses laser range and orientation measurements to project measurement points into the Universal Transverse Mercator coordinate system. Parameters used for coordinate transformations in ALPS are described, as are Interactive Data Language-based methods for gridding EAARL point cloud data to derive digital elevation models. Noise reduction in point clouds through use of a random consensus filter is explained, and detailed pseudocode, mathematical equations, and Yorick source code accompany the report.

  11. Searching for axions and ALPs from string theory

    2012-01-01

    We review searches for closed string axions and axion-like particles (ALPs) in IIB string flux compactifications. For natural values of the background fluxes and TeV scale gravitino mass, the moduli stabilisation mechanism of the LARGE Volume Scenario predicts the existence of a QCD axion candidate with intermediate scale decay constant, f_a ~ 10^9 ... 10^12 GeV, associated with the small cycles wrapped by the branes hosting the visible sector, plus a nearly massless and nearly decoupled ALP associated with the LARGE cycle. In setups where the visible sector branes are wrapping more than the minimum number of two intersecting cycles, there are more ALPs which have approximately the same decay constant and coupling to the photon as the QCD axion candidate, but which are exponentially lighter. There are exciting phenomenological opportunities to search for these axions and ALPs in the near future. For f_a ~ 10^11 ... 10^12 GeV, the QCD axion can be the dominant part of dark matter and be detected in haloscopes ...

    We study photon-ALP conversion by resonance effects in the magnetized plasma of galaxy clusters and compare the predicted distortion of the cosmic microwave background spectrum in the direction of such objects to measurements of the thermal Sunyaev-Zeldovich effect. Using galaxy cluster models based on current knowledge, we obtain upper limits on the photon-ALP coupling constant g of ≲O(10{sup −11} GeV{sup −1}). The constraints apply to the mass range of 2⋅10{sup −14} eV ≲m{sub ALP}≲3⋅10{sup −12} eV in which resonant photon-ALP conversions can occur. These limits are slightly stronger than current limits, and furthermore provide an independent constraint. We find that a next generation PRISM-like experiment would allow limits down to g≈O(10{sup −14} GeV{sup −1}), two orders of magnitude stronger than the currently strongest limits in this mass range.

  17. Military-geographic evaluation of the Julian Alps area

    Directory of Open Access Journals (Sweden)

    Zvonimir Bratun

    1999-12-01

    Full Text Available The Julian Alps have been of military significance since Roman times in a military geographic sense because of its valleys, mountain passes and lines of defence on mountain ridges. They became especially important in the 19th and 20th century. The largest mountain front in World War I was located there,and evidence of that front is still visible today. The border between Italy and Yugoslavia in the heart of the Julian Alps was clearly a line of demarcation along the Soča and Sava watersheds and was reinforced with fortification, obstacles and trenches. During the Cold War, there was an ideological line of demarcation along the western edge of the Julian Alps as well. Military strategy in that area included the use of military geographic approaches in both westerly and easterly directions. After the geopolitical changes of 1991, the Julian Alps no longer had same military geographic significance in terms of Slovenian national security. Today other military activities are more important: training under mountains conditions for NATO soldiers, non-commissioned and commissioned officers takes place in the Pokljuka region and on the Triglav mountain chain. Military facilities have been taken on significance in the terms of tourism as well.

  18. Extragalactic photon-ALP conversion at CTA energies

    2016-01-01

    Magnetic fields in extragalactic space between galaxy clusters may induce conversions between photons and axion-like particles (ALPs), thereby shielding the photons from absorption on the extragalactic background light. For TeV gamma rays, the oscillation length ($l_{\\rm osc}$) of the photon-ALP system becomes inevitably of the same order as the coherence length of the magnetic field ($l$) and the length over which the field changes significantly (transition length $l_{\\rm t}$) due to refraction on background photons. We derive exact statistical evolution equations for the mean and variance of the photon and ALP transfer functions in the non-adiabatic regime ($l_{\\rm osc} \\sim l \\gg l_{\\rm t}$). We also make analytical predictions for the transfer functions in the quasi-adiabatic regime ($l_{\\rm osc} \\ll l, l_{\\rm t}$). Our results are important in light of the upcoming Cherenkov Telescope Array (CTA), and may also be applied to models with non-zero ALP masses.

    Antioxidant activity and polyphenols were quantified in vapour-extracted juice of nine Austrian, partially endemic varieties of sweet cherry (Prunus avium): cv. 'Spätbraune von Purbach', cv. 'Early Rivers', cv. 'Joiser Einsiedekirsche', cv. 'Große Schwarze Knorpelkirsche' and four unidentified local varieties. Additionally the effect of storage was evaluated for six of the varieties. A variety showing the highest antioxidant capacity (9.64 μmol Trolox equivalents per mL), total polyphenols (2747 mg/L) and total cyanidins (1085 mg/L) was suitable for mechanical harvest and its juice did not show any losses of antioxidant capacity and total anthocyanin concentration during storage. The juice of cv. 'Große Schwarze Knorpelkirsche' had also high concentrations of total anthocyanins (873 mg/L), but showed substantial losses through storage. The local Austrian sweet cherry varieties from the Pannonian climate zone are particularly suitable for the production of processed products like cherry juice with high content of anthocyanins and polyphenols.

    A 52-year-old unvaccinated and splenectomized man presented with fever, altered sensorium, bilateral flank pain and chest discomfort accompanied with paroxysmal atrial fibrillation with a rapid ventricular response. An abdominal computed tomography scan was performed, which revealed a right renal infarct and splenosis. Transthoracic echocardiography was performed, which demonstrated an echodense structure on the mitral valve with mitral regurgitation and a vegetation on the aortic valve with aortic regurgitation. Subsequently, he was found to have pneumococcal infective endocarditis, pneumococcal pneumonia and bacterial meningitis, namely Austrian syndrome. He underwent an early aortic valve and mitral valve repair but still had a poor clinical outcome. Renal infarction has a mortality of approximately 13.2%, which is strongly influenced by the underlying diseases and infectious complications. Medical and surgical treatment initiated in a timely manner is often inadequate. The authors report the first case of Austrian syndrome presenting with renal infarction as a clue to an embolic event associated with infective endocarditis in this study.

  1. The Austrian health reform 2013 is promising but requires continuous political ambition.

    Science.gov (United States)

    2014-10-01

    The Austrian health system is much more complex and fragmented than in other OECD countries. In 2013 legislation was adopted to enhance efficiency through better balancing care provision across providers by promoting new primary care models and better coordination of care. Reform objectives should be achieved by cooperative and unified decision making across key stakeholders and by adherence to a budget cap that prescribes fiscal containment on the order of 3.4 billion Euros until 2016. This is priced into the envisaged savings of the current consolidation program. Efforts have been made to bridge the accountability divide by establishing agreements and administrative layers to govern the health system by objectives. Yet, more could have been achieved. For example, cross-stakeholder pooling of funds for better contracting governance and effective purchasing across care settings could have been introduced. This would have required addressing over capacity and fragmentation within social security. At the same time, legal provisions for cooperative governance between Sickness Funds and the governments on the regional level should have been stipulated. The Austrian 2013 reform is interesting to other countries as it aims to ensure better-balanced care at a sustainable path by employing a public management approach to governance relations across key payers of care.

  2. Austrian pine phenolics are likely contributors to systemic induced resistance against Diplodia pinea.

    The molecular basis of the systemic induced resistance (SIR) phenotype known to occur in Austrian pine (Pinus nigra J.F. Arnold) in response to the tip blight and canker pathogen Diplodia pinea (Desm.) remains unclear. Specialized metabolites such as phenolics are considered to be an important component of plant defense, including SIR, but the antimicrobial activity of many of these putative defensive chemicals remains untested at realistic concentrations and in conjunction with each other. Here, we examined the anti-Diplodia activity of several previously identified Austrian pine phenolics associated with SIR by comparing the diameters of fungal colonies grown on media amended with ferulic acid, coumaric acid, taxifolin, pinosylvin, pinosylvin monomethyl ether and lignin. All of the compounds were tested both individually and as clusters (combinations) previously determined to occur in planta in a co-regulated fashion. Both the individual compounds and clusters were tested at constitutive concentrations and pathogen-induced concentrations linked to an SIR phenotype. Lignin possessed the strongest antifungal activity individually, and clusters at the SIR concentrations had the greatest antifungal effects, achieving fungistasis. This study exemplifies the value of evaluating potential biomarkers of resistance at in planta concentrations that are associated with the systemically resistant phenotype, and provides strong evidence that co-regulation of chemical defenses potentiates such a phenotype.

Cependant, comment transférer les savoirs dans une zone comptant quelque 14 millions d’habitants, composée de plusieurs régions linguistiques et culturelles dans lesquelles des milliers de projets sont menés à bien chaque année, et dont tous les acteurs, qui travaillent et vivent dans des contextes complètement différents, sont capables d’apprendre et de tirer profit les uns des autres ? Comment aborder ce genre de cas ?

    Populations of Liparus glabrirostris (Curculionidae: Molytinae), a weevil inhabiting higher altitudes of Central Europe, were sampled from 24 localities in the Alps and Carpathian Mountains, and the geographical structuring of genetic variation was analyzed. Comparison of the concatenated mitochondrial cytochrome oxidase subunit I and subunit II sequences revealed consistent genetic divergence between the populations of L. glabrirostris from different mountain ranges. In phylogenetic analysis using maximum parsimony and median-joining networks, concatenated mitochondrial haplotypes from the Alps and Carpathians clustered as separate lineages, with high bootstrap support. Substantial genetic distances determined between the separated groups ranged from 2.6 to 3.0%, with divergence estimated to have initiated approximately 0.85-0.98 million years ago. The nuclear elongation factor 1α gene was additionally amplified and haplotype analysis showed very low evolutionary divergence (0.2%), with separate clustering as well. The observed divergence suggests that the populations have been isolated for a long time, as a consequence of environmental changes resulting in varying fragmentation of habitats in the Alps and Carpathians, interrupting genetic exchange events and altering the genetic structure of L. glabrirostris populations. On the other hand, comparison of morphological characteristics showed no differences to confirm genetically well differentiated groups of populations. A polymerase chain reaction and restriction fragment length polymorphism-based method was therefore developed to discriminate between the Alpine and Carpathian lineages.

  6. Immediate and delayed signal of slab breakoff in Oligo/Miocene Molasse deposits from the European Alps

    2016-08-01

    High-resolution 32–20 Ma-old stratigraphic records from the Molasse foreland basin situated north of the Alps, and Gonfolite Lombarda conglomerates deposited on the southern Alpine margin, document two consecutive sedimentary responses - an immediate and delayed response - to slab breakoff beneath the central Alps c. 32–30 Ma ago. The first signal, which occurred due to rebound and surface uplift in the Alps, was a regional and simultaneous switch from basin underfill to overfill at 30 Ma paired with shifts to coarse-grained depositional environments in the foreland basin. The second signal, however, arrived several million years after slab breakoff and was marked by larger contributions of crystalline clasts in the conglomerates, larger clast sizes, larger sediment fluxes and shifts to more proximal facies. We propose that this secondary pulse reflects a delayed whiplash-type erosional response to surface uplift, where erosion and sediment flux became amplified through positive feedbacks once larger erosional thresholds of crystalline bedrock were exceeded.

    2009-09-01

    Mainly on the basis of seismic data, we reconstruct magnitude and timing of Miocene to Present vertical movements in the region of the Savigliano basin, an up to 4 km thick succession of Neogene to Quaternary sediments accumulated inside the Alpine arc at the western termination of the Po Plain. We focus, in particular, on the margins of the basin which are the link between the mountain range and the subsiding basin. Seismic data from these regions allow for the definition of upward and downward vertical movements (uplift-exhumation and subsidence) with a spatial and temporal resolution which cannot be attained by other methods. The eastern, southern and western margins of the Savigliano basin display very different geometries of the sedimentary bodies and, therefore, document different vertical movements during Miocene to Present times. The eastern part of the Savigliano basin, and the regions to the E, experienced subsidence followed by exhumation. The southern margin of the basin, in the Cuneo area, was much more stable with Miocene to present formations all pinching-out close to the present day outcropping position of the basement-sedimentary cover contact. In the W, seismic sections record a stage of tilting until the Burdigalian, followed by generalized subsidence which affected also the adjacent regions of the SW Alps. The overall pattern of vertical movements is essentially controlled by the NW-ward migration of a syncline-anticline couple with the synclinal axis presently located in the center of the Savigliano basin. The width of the folds is in the order of 30-60 km (1/2 wavelength). In map view, the trace of the fold axes changes from N-S in the Savigliano basin to E-W in the Alessandria basin.

    Full Text Available Daphnia middendorffiana has an arctic, circumpolar distribution, with some isolated southerly populations restricted to mountainous areas, including the Alps. In this paper, new records of Daphnia middendorffiana on the Alps are reported. The species was regularly recorded in several samples collected from 2006 to 2009 in four high altitude lakes in the Gran Paradiso National Park (GPNP during the ice free period. This is the third finding for the Alps and the described populations are the largest. Chemical and morphometric features of the lakes are provided, the morphology of the Daphnia middendorffiana from GPNP is described as well as some aspects concerning its ecology. The studied lakes are small, oligotrophic (total phosphorus ranged from 0 to 7 μg L-1 and well preserved from acidification risk (pH ranged from 6.45 to 8.14. D. middendorffiana is the largest zooplanktonic crustacean inhabiting the Alpine lakes in GPNP reaching 3.43 mm in length; the morphological analysis noted some differences within the studied populations; however there is a clear resemblance to the only Alpine population previously described (from Central Alps, Bognanco Valley, Lake Campo IV and to the arctic populations. D. middendorffiana in GPNP lives at low density levels, reaching higher densities in late August and early September. No males have been found during the sample campaign confirming its ability to produce asexual viable diapauses eggs. This study confirms the attitude of this species for cold and oligotrophic waters and increases the current knowledge on the geographical distribution, morphology and ecology of this species in Alpine environments. The finding of D. middendordorffiana in the GPNP poses interesting issues concerning the phylogeography of Alpine Daphnia middendorffiana, as well as raising need for conservation efforts aimed at keeping the populations safe from several global and local threats, such as climate warming and the ecological

    Full Text Available The bivalve Daonella Mojsisovics, 1874 is very common in the Middle Triassic pelagic facies, whereas the record of this genus from shallow water limestones is rare. In the present paper a new species of Daonella, named D. pseudograbensis, is described from the Esino Limestone, a Ladinian (Middle Triassic carbonate platform in the central Southern Alps. The species is described from Brembana Valley, where the Esino Limestone is rather rich in bioclastic lenses yielding faunas with bivalves, cephalopods, gastropods, brachiopods, corals and calcareous algae. Daonella pseudograbensis n. sp. is based on very well preserved specimens, which are often articulated and closed, all coming from the same locality. The new species shows a narrow range of intraspecific and ontogenetic morphologic variations. It is easy distinguishable from the other species of the genus for the outline and ornamentation; it therefore differs from D. grabensis Kittl, 1912, the most similar species, for the longer anterior dorsal margin.Pdf

    The first Austrian Allergy Report is a compilation of all available epidemiological data relating to allergies in Austria. According to this report the cumulative prevalence of allergies in the Viennese population is 27.6% for men and 32.2% for women and the period prevalence in the year before questioning 19.6% and 22.4% respectively. 20.8% of men and 23.1% of women reported about allergies at health examinations. However, an allergy sensitivity to at least one inhalation allergen, verifiable by means of a prick test, is detectable in 50.8% of the general population and in 39.3% of those free from ailments. Analysis of the hospital discharge statistics of all Austrian hospitals shows that around 12,000 people per year were admitted on grounds of an allergy. In accordance with international studies some population sub groups are more often affected than others. Women suffer from allergies somewhat more frequently than men, although the sex difference is reversed among children. Allergies occur in all age groups, with most studies showing that people in their twenties are most frequently affected. People with higher levels of education, in more highly qualified jobs and living in urban areas are more commonly affected by allergies than people from lower socio-economic levels and rural communities. The internationally identified increase in trend can also be identified in Austria with a 2fold, 3.6fold, and 4.6fold increase in the prevalence of hay fever, asthma and atopic eczema respectively, determined from the military health examinations of all recruits for national service between 1986 and 2003/04, although a clear decline in allergy prevalence was registered between 2003/04 and 2005. Health reports like the first Austrian Allergy Report provide the basis for international comparison of basic data. These data also enable the evaluation of the impact of different diseases on the health system as well as the development of public health strategies.

    2004-01-01

    A consortium of Austrian scientists (ARCEM) carried out a multidisciplinary environmental study on Austrian surface and ground waters including chemical monitoring, bioindication, risk assessment and risk management for selected endocrine disrupters: 17beta-estradiol, estriol, estrone, 17alpha-ethinylestradiol, 4-nonylphenol, 4-nonylphenol ethoxylates (4-NP1EO, 4-NP2EO) and their degradation products, ocytlphenol, ocytlphenol ethoxylates (OP1EO, OP2EO) as well as bisphenol A. To obtain data representative for Austria, a material flow analysis served to select relevant compounds and water samples were collected monthly over one year at those sites routinely used in Austrian water quality control. The following results were obtained and conclusions drawn: 1. Chemical monitoring: As compared to other countries, relatively low levels of pollution with endocrine disrupters were detected. 2. Bioindication: In the surface waters under study, male fish showed significant signs of feminization and demasculinization (increased production of the egg-yolk protein and histological changes of the gonads. 3. Risk assessment: For humans, exposure via either drinking water abstraction (ground water) or fish consumption was considered. The exposure levels of the compounds under study were below those considered to result in human health risks. Likewise, for bisphenol A and octylphenols, there was no indication for risk posed upon the aquatic environment (fish). However, nonylphenol or 17alpha-ethinylestradiol exposure along with results of bioindication (2) suggest a borderline estrogenic activity in a considerable number of surface waters. Consequently the emissions of these substances into the surface waters affected have to be reduced. 4. Risk management: Waste water treatment experiments revealed a positive correlation between the removal rate of endocrine disrupters from the waste water and the sludge retention time in the treatment plants. These substances are removed to a

    Soil organic matter (SOM) balance depends on climate and climate change due to the impact on SOM turnover conditions as well as on cropping and crop yields. The Austrian Carbon calculator (ACC) is a tool for the comparison of future land use scenarios with the current agriculture in order to identify opportunities to sustain the SOM balance. The ACC can be used in a regional mode as well as in local mode for the assessment of single farm fields. The assessment is based on the concept of Biologic Active Time (BAT). BAT is calculated based on soil data from the Austrian eBod map and climate data for past and future on a 1 km grid. The ACC was implemented for the regions Mühlviertel and Marchfeld. Crop yields are calculated based on statistics from the Austrian agricultural sub regions "Kleinproduktionsgebiet" for the most common crops. The regional scenarios consist of the abundance of crops, the part of nitrogen added as mineral fertilizer and the part of irrigation. The local soil management is calculated based on crop rotations with yields, organic amendments, irrigation and the tillage system (ploughed or not ploughed). The SOM balance is assessed with the reproduction index (REP_IX) that is calculated as the quotient from carbon reproduction (Carbon flux into SOM) and the BAT value. This way REP_IX includes the impact from management as well as from climate. If the future management will not change REP_IX the SOM balance will be the same as well. This methodology helps to adapt the management to future conditions to sustain the current SOM conditions without an absolute assessment if the current SOM state is optimal or not. The regional results of ACC will be made available as thematic maps on the project web site. For local applications farmer can use the tool to analyze their special site conditions and management plans to assess the management options under climate change conditions. The described concept can be improved if reliable information about the

    Background and Purpose This study analyzed the number of patients with ischemic strokes recorded in the Austrian Stroke-Unit Registry with the aim of projecting this number from 2012 to 2075 and to highlight that the Austrian health system will face a dramatic increase in older patients within the next few decades. Methods Current demographic information was obtained from EUROSTAT, and information on age- and sex-stratified 1-year incidence rates of ischemic stroke were obtained from the Austrian Stroke-Unit Registry. Sensitivity analysis was performed by analyzing the projections based on predicted ageing, main, and growth population scenarios, and with stratification by age and gender. Results The total number of ischemic strokes recorded in the Austrian Stroke-Unit Registry was 8,690 in 2012 and is expected to increase to 15,826, 15,626, or 18,134 in 2075 according to the ageing, main, and growth scenarios, respectively. The corresponding numbers of patients are projected to increase or decrease within different age strata as follows (100%=number of registered ischemic strokes in 2012): 0–40 years, 100%/99% (males/females); 40–50 years, 83%/83%; 50–60 years, 98%/97%; 60–70 years, 126%/119%; 70–80 years, 159%/139%; 80–90 years, 307%/199%; and 90+ years, 894%/413%. Conclusions The ageing population in Austria will result in the number of patients increasing considerably from 2012 to 2075, to 182%, 180%, or 208% (relative to 100% in 2012) according to the ageing, main, and growth scenarios, respectively; the corresponding value among those aged 80+ years is 315%, 290%, or 347%. These figures demonstrated the importance of improving primary preventive measures. The results of this study should provide a basis for discussions among health-care professionals and economists to face the future large financial burden of ischemic stroke on the Austrian health system.

    To investigate the vertical profiles of air pollutants in the boundary layer, aircraft and balloon-born measurements and measurements using a cable car as an instrument platform have been performed in different parts of the Alps. This on-line monitoring of atmospheric pollutants requires expensive and sophisticated techniques. In order to control ambient air quality in remote regions, where no infrastructure like power supply is available, simple instruments are required. The objective of this study, which was coordinated and evaluated by the GSF-Forschungszentrum fuer Umwelt und Gesundheit was first, to investigate the vertical distribution of ozone in different parts of the Alps and secondly, in addition to continuous analyser measurements, to test monitoring by means of two types of passive samplers. The selection of these samples - one for one week use and another one for two week application - was based on a passive sampler intercomparison done in a preliminary study one year earlier.

    Autoimmune lymphoproliferative syndrome (ALPS) is a rare disease caused by defective lymphocyte apoptosis and is characterized by non-malignant lymphoproliferation, hepatosplenomegaly, autoimmune manifestations and increased risk of both Hodgkin's and non-Hodgkin's lymphoma. Most forms of the disease are due to germ line mutations of the FAS gene and manifest during the first years of life with fluctuating lymphadenopathies, hemolysis, immune thrombocytopenia. During the second decade of life disease manifestations improve spontaneously but autoimmune problems still occur and there is an increased risk of lymphoproliferative malignancy. We describe a typical case of ALPS in a now 44 year old man, followed since the age of 2 for disease manifestations that were unclear at the beginning.

    Mountain vegetation is strongly affected by temperature and is expected to shift upwards with climate change. Dynamic vegetation models are often used to assess the impact of climate on vegetation and model output can be compared with paleobotanical data as a reality check. Recent paleoecological studies have revealed regional variation in the upward shift of timberlines in the Northern and Central European Alps in response to rapid warming at the Younger Dryas/Preboreal transition ca. 11 700 years ago, probably caused by a climatic gradient across the Alps. This contrasts with previous studies that successfully simulated the early Holocene afforestation in the (warmer) Central Alps with a chironomid-inferred temperature reconstruction from the (colder) Northern Alps. We use LandClim, a dynamic landscape vegetation model to simulate mountain forests under different temperature, soil and precipitation scenarios around Iffigsee (2065 m a.s.l.) a lake in the Northwestern Swiss Alps, and compare the model output with the paleobotanical records. The model clearly overestimates the upward shift of timberline in a climate scenario that applies chironomid-inferred July-temperature anomalies to all months. However, forest establishment at 9800 cal. BP at Iffigsee is successfully simulated with lower moisture availability and monthly temperatures corrected for stronger seasonality during the early Holocene. The model-data comparison reveals a contraction in the realized niche of Abies alba due to the prominent role of anthropogenic disturbance after ca. 5000 cal. BP, which has important implications for species distribution models (SDMs) that rely on equilibrium with climate and niche stability. Under future climate projections, LandClim indicates a rapid upward shift of mountain vegetation belts by ca. 500 m and treeline positions of ca. 2500 m a.s.l. by the end of this century. Resulting biodiversity losses in the alpine vegetation belt might be mitigated with low

    Full Text Available International capital flows can be hampered by a variety of barriers such as transaction costs, information costs, and legal restrictions. The solution in this situation can be dual listing. The framework of the research presented here assumes that domestic securities are dually listed on a foreign capital market, while none of the foreign securities is dually listed on the domestic capital market. This paper is concerned with a dependence analysis of the log-levels and returns of Austrian stocks listed in Frankfurt and Vienna. The important issue is dynamic linear and non-linear causality between log-levels (returns of prices and the indices ATX and DAX. In this context the important directions of causality are found along with the level of relations of the selected types of causality.

  3. Requirements for Electronic Delivery Systems in eGovernment - An Austrian Experience

    Tauber, Arne

    Electronic mailing systems are the dominant communication systems in private and business matters. Public administrations deliver documents to citizens and businesses - subpoenas, legal verdicts, notifications, administrative penalties etc. However, official activities are more strongly linked to legal regulations than in civil law. Delivery of crucial and strictly personal documents raises the demand for qualified identification and non-repudiation services as featured by registered mail in the paper world. Legal requirements for electronic delivery carried-out by public administrations (eDelivery) cannot be fulfilled by standard certified mailing systems. Although the requirements for eDelivery systems may differ due to national legal regulations, this paper discusses common requirements and challenges on an abstract level. Moreover, we show how these requirements have been addressed by introducing the Austrian eDelivery system for eGovernment applications.

    Directory of Open Access Journals (Sweden)

    Philipp Bagus

    2010-02-01

    Full Text Available Authors in the Austrian tradition have made the credit expansion of a fractional reserve banking system as the prime cause of business cycles. Authors such as Selgin (1988 and White (1999 have argued that a solution to this problem would be a free banking system. They maintain that the competition between banks would limit the credit expansion effectively. Other authors such as Rothbard (1991 and Huerta de Soto (2006 have gone further and advocated a 100 percent reserve banking system ruling out credit expansion altogether. In this article it is argued that a 100 percent reserve system can still bring about business cycles through excessive maturity mismatching between deposits and loans.

    Reaction mechanisms leading to microbially induced concrete corrosion (MICC) are highly complex and often not fully understood. The aim of the present case study is to contribute to a deeper understanding of reaction paths, environmental controls, and corrosion rates related to MICC in a modern Austrian sewer system by introducing an advanced multi proxy approach that comprises gaseous, hydro-geochemical, bacteriological, and mineralogical analyses. Various crucial parameters for detecting alteration features were determined in the field and laboratory, including (i) temperature, pH, alkalinity, chemical compositions of the solutions, (ii) chemical and mineralogical composition of solids, (iii) bacterial analysis, and (iv) concentrations of gaseous H2S, CH4 and CO2 within the sewer pipe atmosphere. An overview of the field site and analytical results, focusing on reaction mechanisms causing the corrosion, as well as possible remediation strategies will be presented.

    According to Austrian Law, dose assessments in workplaces with potentially enhanced radon exposures are mandatory since 2008, including tourist mines and caves. A pilot study was carried out to evaluate the situation to test the measurement methods and to specify the main parameters controlling the radon concentration in tourist mines and caves. Radon was measured in six mines and three caves for 1 y, along with determining thoron and equilibrium factors and taking into account climatic, geological and site-related effects. The radon concentrations have a seasonal dependence with maximum in summer and minimum in winter, related to natural ventilation. Radon concentrations in the karst caves were quite low, as it was in the salt mine, whereas radon concentrations in copper and silver mines were high. The dose assessment of the employees yielded doses above 6 mSv a(-1) only in the copper mine.

    Full Text Available The “Steirische Eisenstraße” is a region located in the province of Styria in Austria, which has been struggling with a massive shift in population and age structure for some time. In 2012/13 the Austrian social festival Keep the Ball Rolling is taking place in this region. Over a period of 18 months, the social festival is providing opportunities to think of their own environment. Consequently, they can develop and implement ideas for good cohabitation and put these into practice. The main focus of this article is the demographic presentation of the “Steirische Eisenstraße” region, according to population, employment and age structure. The introduction of the social festival is fundamental in initiating successful change processes.

    The Austrian Soil Science Society (ASSS), founded in 1954, is a non-profit organisation aiming at furthering all branches of soil science in Austria. The ASSS provides information on the current state of soil research in Austria and abroad. It organizes annual conferences for scientists from soil and related sciences to exchange their recent studies and offers a journal for scientific publications. Annually, ASSS awards the Kubiena Research Prize for excellent scientific studies provided by young scientists. In order to conserve and improve soil science in the field, excursions are organized, also in cooperation with other scientific organisations. Due to well-established contacts with soil scientists and soil science societies in many countries, the ASSS is able to provide its members with information about the most recent developments in the field of soil science. This contributes to a broadening of the current scientific knowledge on soils. The ASSS also co-operates in the organisation of excursions and meetings with neighbouring countries. Several members of the ASSS teach soil science at various Austrian universities. More detail on said conferences, excursions, publications and awards will be given in the presentation. Beside its own scientific journal, published once or twice a year, and special editions such as guidebooks for soil classification, the ASSS runs a website providing information on the Society, its activities, meetings, publications, awards and projects. Together with the Environment Agency Austria the ASSS runs a soil platform on the internet. It is accessible for the public and thus informs society about soil issues. This platform offers a calendar with national and international soil events, contacts of soil related organisations and networks, information on national projects and publications. The society has access to products, information material and information on educational courses. Last but not least information on specific soil

    Based on the new Euratom Basic Safety Standards (BSS), all EU member states will be obliged to design a strategy to address long-term risks from radon exposure, which is laid down in the 'national radon action plan'. In Austria, the National Radon Centre is responsible for the development of the action plan. This paper presents the current and planned radon protection activities on the way to establish the radon action plan--like the national radon database, the definition of radon risk areas by improving the existing radon map, as well as strategies and activities to increase the radon awareness of the public and decision-makers and to involve the building sector. The impact of and the need for actions caused by the BSS requirements on the Austrian radon legislation, strategy and programme are discussed.

    The aim of this study was to investigate the antimicrobial resistance, resistance gene patterns and genetic relatedness of a collection of Austrian methicillin-resistant Staphylococcus aureus (MRSA) isolates from companion animals and horses. A total of 89 non-repetitive MRSA isolates collected during routine veterinary microbiological examinations from April 2004 to the end of 2012, and one isolate from 2013 were used for this study. The presence of mecA and other resistance genes was confirmed by PCR. Isolates were genotyped by spa typing, two multiple-locus variable-number tandem repeat analyses (MLVA) analyses, SCCmec typing and multilocus sequence typing (MLST). PCR targeting Panton-Valentine leukocidin (PVL) and detection of staphylococcal enterotoxins (SE), toxic shock syndrome toxin (TSST) was performed using PCR assays. Antimicrobial susceptibility testing was performed. Five sequence types (STs-ST398, ST254, ST22, ST5 and ST1), SCCmec types II, IVa, V, and non-type-abele, 8 spa-types (t003, t011, t036, t127, t386, t1348, and t4450), and two isolates could not be assigned, 21 MLVA-14Orsay types Multiplex-PCR MLVA (mMLVA) displayed 17 different MLVA types. The present study is the most comprehensive dealing with MRSA from Austrian companion animals and horses. The results confirm that MRSA ST398 is present in a wide range of animal species and is predominant especially in horses. In other companion animals it is unclear whether the infections with the different MRSA isolates investigated in the present study truly represents a rare phenomenon or may be an emerging problem in companion animals.

    With their high beam energy and intensity, existing and near-future proton beam dumps provide an excellent opportunity to search for new very weakly coupled particles in the MeV to GeV mass range. One particularly interesting example is a so-called axion-like particle (ALP), i.e. a pseudoscalar coupled to two photons. The challenge in proton beam dumps is to reliably calculate the production of the new particles from the interactions of two composite objects, the proton and the target atoms. In this work we argue that Primakoff production of ALPs proceeds in a momentum range where production rates and angular distributions can be determined to sufficient precision using simple electromagnetic form factors. Reanalysing past proton beam dump experiments for this production channel, we derive novel constraints on the parameter space for ALPs. We show that the NA62 experiment at CERN could probe unexplored parameter space by running in 'dump mode' for a few days and discuss opportunities for future experiments such as SHiP.

  14. The central Vienna Basin Transfer Fault - lack of knowledge or seismic gap?

    2012-12-01

    The Vienna Pull-Apart Basin between the Alps and the Carpathians is characterized by a moderate level of historical seismicity (Imax/Mmax = 8/5.2) focused along the NNE-SSW striking left-lateral Vienna Basin Transfer Fault (VBTF) that delimits the basin towards the east. Displacement rates determined from GPS geodesy and geological markers range between 1.5 - 2.0 mm/a. However, seismic slip rates calculated from cumulative scalar seismic moments for different segments along the fault are quite heterogeneous, varying from 0.5-1.1 mm/a at the southern and northern tips to an apparently seismically totally locked segment in the central part of the basin, the so-called Lassee segment, close to the city of Vienna. Only two small earthquakes in the M3 to M4 range have been observed along this segment, in contrast to geomorphic and subsurface geophysical data that indicate that this fault segment has sustained horizontal Quaternary displacements of several tens of meters, generated by several subfaults associated with a negative flower structure. The seismic potential of this segment, which is the closest to both the Austrian capital of Vienna and the Slovak capital Bratislava, is therefore one of the key questions for the seismic hazard for those cities. Our new data from a paleoseismological trench at the Lassee segment of the VBTF is located at the tectonically controlled western margin of a Pleistocene Danube terrace (200-300 ka). Here, the VBTF has produced a ~ 25 m high scarp. The main fault within the trench displaces the coarse Pleistocene gravels and intercalated sand lenses, whose layering dips towards the fault and against the direction of flow, based on paleo-current indicators. In addition, several smaller faults are observed to have vertical displacements of up to 0.5 m. The hanging wall consists of colluvial sediments and sandy layers from extreme flooding events. As a preliminary result, at least three different colluvial wedges can be distinguished at the

    One of the main actions of the AlpArray European initiative is the deployment of a dense seismic broad-band network, that complements the existing permanent stations. This will ensure a spatially homogeneous seismic coverage of the greater Alpine area for at least two years, allowing a great number of innovative scientific works to be carried out. Our contribution to the AlpArray Seismic Network consists in the deployment of 24 temporary broad-band stations: three in Switzerland, twelve in Italy, three in Croatia, three in Bosnia and Herzegovina and three in Hungary. This deployment is lead by ETH Zurich and founded by the Swiss-AlpArray Sinergia programme by SNSF, and is the result of a fruitful collaboration between five research institutes. Stations were installed between Autumn and Winter 2015. Our installations are both free field and in-house and consist of 21 STS-2 and 3 Trillium Compact sensors equipped with Taurus digitizers and 3G telemetry sending data in real time to the ETH EIDA node. In this work, we present sites and stations setting and we discuss in details the characteristics in terms of site effects and noise level of each station. In particular we analyse the power spectral density estimates investigating the major source of noise and the background noise related to seasons, time of the day, human activities and type of installation. In addition we will show examples of data usage - i.e. earthquake locations, noise cross correlations, measures of surface wave dispersion curves.

    Late-orogenic indentation by rigid lithospheric plates and microplates into softer orogenic wedges leads to post-collisional shortening, lithospheric thickening and vertical and lateral extrusion. The European Eastern and Southern Alps represent a prime example of indenter tectonics. Their Late Neogene geodynamic framework is influenced primarily by the ca. NW-ward motion and counterclockwise rotation of the Adriatic microplate with respect to Europe, which resulted in an oblique, dextral transpressional setting. In this study we refine the late-stage exhumation pattern related to indentation of the eastern Adriatic indenter, i.e. the still northward pushing triangular northeastern part of the Southalpine block that indented the Eastern Alps. New apatite (U-Th)/He and apatite fission track thermochronometry data come from (1) the Karawanken Mountains adjacent to the eastern Periadriatic fault along the northeastern edge of the indenter and from (2) the central-eastern Southern Alps from within the indenter and from its western edge. We find apatite (U-Th)/He ages from the Karawanken Mountains ranging between 11 and 6 Ma, which indicate an episode of fault-related exhumation leading to the formation of a positive flower structure and an associated peripheral foreland basin as well as lateral activity along the Periadriatic fault system. Apatite (U/Th)/He and fission-track data combined with previous data from the Southern Alps indicate that exhumation largely occurred during the Late Miocene, too, and was maximized along thrust systems, with highly differential amounts of vertical displacement along individual structures. Our new data contribute to mounting evidence for widespread Late Miocene tectonic activity in the Eastern and Southern Alps. They demonstrate a shift from deformation and exhumation concentrated within the Tauern Window at the beginning of the indentation process, to less pronounced, but more widespread exhumation along the edges as well as the

    Connectedness to nature (CN) influences motivation to have contact with outdoor natural environments. Spending leisure time in natural environments is beneficial for human health and well-being. Besides these positive effects, health risks of open-air activities are mainly related to unprotected sun light exposure-associated acute and chronic skin hazards. Thus, we conducted a cross-sectional, representative telephone survey among Austrian residents to study the association of perceived CN level with sun-exposure knowledge, tanning habits, and sun protective behaviour. In total, 1,500 study subjects (50.5% females) participated in this questionnaire survey. Although knowledge about tanning and motives to tan were similar among genders, females performed more photoprotective measures and were more connected to nature (all p nature connectedness and skin health-relevant recreational habits of Austrian residents.

    Full Text Available The relationship and interaction between quantitative (number and dimensions of trees and value indicators in Austrian pine plantations were researched in Forest Management Unit „Subotičke Šume” (Forest Estate „Sombor” - FA „Subotica”. As the measurement of quantitative elements is more simple, their effect on wood value can be used as a rather reliable support in the value estimation of standing trees. The analysis of the research results shows that there is a strong inter-relationship of the study elements, so they can be a good foundation for the estimation of standing timber value in artificial Austrian pine plantations at the given site.

    The Eastern Alps are characterised by the presence of three main tectonic units, such as the Lower, Middle and Upper Austroalpine, which overlie the Penninicum (Tollmann, 1977). The Upper Austroalpine unit consists of the Northern Calcareous Alps (NCA) overlying the Greywacke zone and corresponding to the Graz Paleozoic, Murau Paleozoic and the Gurktal Nappe. Evaporitic rocks are lacking in the later ones. The Northern Calcareous Alps are a detached fold and thrust belt. The sedimentation started in the Late Carboniferous or Early Permian, the age of the youngest sediments being Eocene. The NCA are divided into the Bajuvaric, Tirolic and Juvavic nappe complexes. The evaporitic Haselgebirge Formation occurs in connection with the Juvavic nappe complex at the base of the Tirolic units (Leitner et al., 2013). The Haselgebirge Formation consists mainly of salt, shales, gypsum and anhydrite and includes the oldest sediments of the NCA. The age of the Haselgebirge Formation, established by using spors and geochronological data, is Permian to Lower Triassic. For the Northern Calcareous Alps, the mineralogy of sulphate accumulations consists mainly of gypsum and anhydrite and subordonates of carbonates. The carbonates as magnesite, dolomite and calcite can be found either as singular crystals or as small accumulations within the hosting gypsum. Sulfides (sphalerite, galena, pyrite), sulfarsenides (enargite, baumhauerite) and native sulphur enrichments are known from several deposits (Kirchner, 1987; Postl, 1990). The investigated samples were selected from various gypsum and halite rich deposits of the Northern Calcareous Alps. A total of over 20 samples were investigated, and both oxygen and sulfur isotopic composition were determined for anhydrite, gyps, polyhalite, blödite and langbeinite. The sulfur isotopic values vary between 10.1 to 14 ‰ (CDT), with three values higher than 14 ‰. The Oxygen isotopic values show a range from 9 to 23 ‰ (SMOW). The sulfur

    Autoimmune lymphoproliferative syndrome (ALPS) is associated with mutations that impair the activity of lymphocyte apoptosis proteins, leading to chronic lymphadenopathy, hepatosplenomegaly, autoimmunity, and an increased risk of lymphoma. We investigated the utility of fluorodeoxyglucose positron emission tomography (FDG-PET) in discriminating benign from malignant lymphadenopathy in ALPS. We report that FDG avidity of benign lymph nodes in ALPS can be high and, hence, by itself does not imply presence of lymphoma; but FDG-PET can help guide the decision for selecting which of many enlarged nodes in ALPS patients to biopsy when lymphoma is suspected.

    The ALPS Collaboration runs a 'Light Shining through a Wall' (LSW) experiment to search for photon oscillations into 'Weakly Interacting Sub-eV Particles' (WISPs) often predicted by extensions of the Standard Model. The experiment is set up around a superconducting HERA dipole magnet at the site of DESY. Due to several upgrades of the experiment we are able to place limits on the probability of photon-WISP-photon conversions of a fewx10{sup -25}. These limits result in today's most stringent laboratory constraints on the existence of low mass axion-like particles, hidden photons and minicharged particles.

    Martin, Eric; Durand, Yves

    The distribution of winter precipitation as analysed by the meteorological analysis system SAFRAN is validated using data from two test sites. This system, applied to the French Alps, shows that the frequency of high precipitation events is not necessarily linked to mean precipitation. Using a downscaling procedure, the system was run with General Circulation Model (GCM) outputs. The corresponding snow cover is derived with the snow model CROCUS. The results are very sensitive to the quality of the GCM run. The analyses of two future climate scenarios show that drastic changes in precipitation distribution may occur in the future.

  7. Chemical denudation rates of a small torrential catchment in the Northern Calcareous Alps

    Our understanding on the decay of alpine landscapes and the pace of landscape adjustment to climatic or tectonic changes rely on catchment wide erosion rates. In general, these data stem from cosmogenic isotope dating of quartz grains and are therefore only applicable at catchments providing suitable bedrock. However, denudation caused by the dissolution of rocks is not explicitly considered by this method. In the Northern Calcareous Alps (NCA) crystalline rocks are missing and intensive karstification suggests that chemical denudation is an important player for destroying topography. In this study we present chemical denudation rates derived from measuring the dissolved load of an alpine catchment located in the country of Salzburg, Austria. The catchment has a drainage area of about 7 km2 and is predominantly covered by limestone rich glacial deposits and carbonatic rocks as characteristic for the NCA. In order to obtain catchment wide chemical denudation rates we have integrated discharge time series that where measured by a permanent water gauge of the Austrian Service for Torrent and Avalanche Control to compute the total discharge of the investigated catchment over a period of one year. During the same period samples were taken at several campaigns to consider variations of the dissolved load. Samples were taken at high and low run-off conditions to study the effect of precipitation and at different locations along the tributaries to account for lithological variations of the river beds on the dissolved load. The concentrations of various cations in water samples were measured by the ICP-MS facility at the University of Graz. For the investigation period of one year 3.02 ∗ 106m3 of discharge was measured at the catchment outlet. The summed cation-concentration is varying between about 85 mg/l for dry-conditions and 75 mg/l for rainy-conditions at the gauge and consists predominantly of Ca+ cations. Based on the total discharge of the river integrated over a

    Full Text Available The causes for the Middle to Late Jurassic tectonic processes in the Northern Calcareous Alps are still controversially discussed. There are several contrasting models for these processes, formerly designated “Jurassic gravitational tectonics”. Whereas in the Dinarides or the Western Carpathians Jurassic ophiolite obduction and a Jurassic mountain building process with nappe thrusting is widely accepted, equivalent processes are still questioned for the Eastern Alps. For the Northern Calcareous Alps, an Early Cretaceous nappe thrusting process is widely favoured instead of a Jurassic one, obviously all other Jurassic features are nearly identical in the Northern Calcareous Alps, the Western Carpathians and the Dinarides. In contrast, the Jurassic basin evolutionary processes, as best documented in the Northern Calcareous Alps, were in recent times adopted to explain the Jurassic tectonic processes in the Carpathians and Dinarides. Whereas in the Western Carpathians Neotethys oceanic material is incorporated in the mélanges and in the Dinarides huge ophiolite nappes are preserved above the Jurassic basin fills and mélanges, Jurassic ophiolites or ophiolitic remains are not clearly documented in the Northern Calcareous Alps. Here we present chrome spinel analyses of ophiolitic detritic material from Kimmeridgian allodapic limestones in the central Northern Calcareous Alps. The Kimmeridgian age is proven by the occurrence of the benthic foraminifera Protopeneroplis striata and Labyrinthina mirabilis, the dasycladalean algae Salpingoporella pygmea, and the alga incertae sedis Pseudolithocodium carpathicum. From the geochemical composition the analysed spinels are pleonastes and show a dominance of Al-chromites (Fe3+–Cr3+–Al3+ diagram. In the Mg/(Mg+ Fe2+ vs. Cr/(Cr+ Al diagram they can be classified as type II ophiolites and in the TiO2 vs. Al2O3 diagram they plot into the SSZ peridotite field.

    Full Text Available The influence of seed provenances and seedling production methods on quality of one and two years old seedlings of Austrian pine were investigated. Seeds from three provenances of Austrian pine (Goc, Studenica and Sargan were used for seedlings production, combined with three production methods: (i the modified seedbeds (bare-root, (ii the container type Plantagrah II and (iii the container type Gocko. Provenance, as well as the combined influence of provenance and production method had minimal influence on the variability of one and two years old Austrian pine seedlings. Nevertheless, the production method had the highest influence. The production system, besides its importance in nursery, will have a high influence on seedlings growth during the first year after planting. Considering the results of this study (e.g. the highest values of the diameter, number of lateral roots, shoot and root dry weight, and quality index and the lowest value of SQ and satisfactory value of S:R, we can conclude that the seedlings produced in container type Gocko led to the highest seedlings quality, recommended especially for afforestation on hard sites.

Methods. he subcutaneous adipose tissue (SAT) distribution patterns in 553 Austrian (A) and Estonian (E) clinically healthy normal weight boys aged 11.1 (±0.8) years were analysed. We applied the patented optical device Lipometer which determines the individual subcutaneous adipose tissue topography (SAT-Top). Results. Total body fat did not differ significantly between E and A boys. A discriminant analysis using all Lipometer data, BMI, and the total body fat (TBF) yielded 84.6% of the boys correctly classified in Estonians and Austrians by 9 body sites. A factor analysis identified the SAT distribution of E as critically similar to male adult patients with coronary heart disease (CHD). Conclusions. We show in normal weight Estonian boys a highly significant decreased fat accumulation on the lower body site compared to age matched Austrian males. This SAT-Top phenotype may play an important role for the increased cardiovascular risk seen in the Estonian population.

    Within the project FarmClim ("Farming for a better climate") we assessed recent N2O emissions from two selected regions in Austria. Our aim was to deepen the understanding of Austrian N2O fluxes regarding region specific properties. Currently, N2O emissions are estimated with the IPCC default emission factor which only considers the amount of N-input as an influencing factor for N2O emissions. We evaluated the IPCC default emission factor for its validity under spatially distinct environmental conditions. For this two regions for modeling with LandscapeDNDC have been identified in this project. The benefit of using LandscapeDNDC is the detailed illustration of microbial processes in the soil. Required input data to run the model included daily climate data, vegetation properties, soil characteristics and land management. The analysis of present agricultural practices was basis for assessing the hot spots and hot moments of nitrogen emissions on a regional scale. During our work with LandscapeDNDC we were able to adapt specific model algorithms to Austrian agricultural conditions. The model revealed a strong dependency of N2O emissions on soil type. We could estimate how strongly soil texture affects N2O emissions. Based on detailed soil maps with high spatial resolution we calculated region specific contribution to N2O emissions. Accordingly we differentiated regions with deviating gas fluxes compared to the predictions by the IPCC inventory methodology. Taking region specific management practices into account (tillage, irrigation, residuals) calculation of crop rotation (fallow, catch crop, winter wheat, barley, winter barley, sugar beet, corn, potato, onion and rapeseed) resulted in N2O emissions differing by a factor of 30 depending on preceding crop and climate. A maximum of 2% of N fertilizer input was emitted as N2O. Residual N in the soil was a major factor stimulating N2O emissions. Interannual variability was affected by varying N-deposition even in case

    Very promising dark matter candidates are axion-like particles: sub-eV particles that are expected to (weakly) interact with photons in the presence of a static electric or magnetic field. This interaction can turn photons into axions and back into photons. Hence, in order to generate axions, we will set up a 100 meter long Fabry-Perot cavity that can hold a 150,000 watt laser field and have a 5.3 tesla magnetic field along the entire length. If the theory holds up, a fraction of the photons should transform into relativistic axions. These axions would then propagate through any optical barrier and enter a matched cavity that is situated within an identical magnetic field. Here, some of the axions should turn back into photons of equal energy. Thus these photons resonate in the otherwise empty cavity where they can be detected. It is unknown if axion-like particles exist in the targeted mass range. However, the ALPS detection principle is very convenient because we will know the exact energy of the regenerated photons beforehand thus making a detection much easier.The final stage of the ALPS experiment will be completed by 2019 at the German Electron Synchrotron (DESY) site in Hamburg, Germany. This work is supported by grants from the Heising-Simons Foundation and the National Science Foundation.

    Trichophyton tonsurans is the primary etiologic agent of fungal infections in the pediatric population. Establishing techniques that facilitate strain discrimination offer the opportunity to investigate the relationship between fungal genotype, biochemical phenotype and disease presentation in the host. In the process of expanding efforts to elucidate intra-specific genetic variability in T. tonsurans, we have identified 2 genetic polymorphisms in the ALP1 gene: a fragment length polymorphism in the 5'UTR and a single SNP (G-->A) within the 3'UTR. Full sequence data revealed that the length polymorphism was constituted by a 16 bp repeat element, present in tandem from 3 to 6 times depending on the strain. Quantitative RT-PCR analysis demonstrated a clear association between the length polymorphism and ALP1 mRNA transcript levels. Not only do the sequence variations identified in this study increase our ability to discriminate T. tonsurans strains, but they also reveal the presence of a genetic variation with functional consequences at the transcript level that may play a role in regulating disease severity.

    The Vienna surgeon Joseph Plenck first listed individual skin lesions, some of which we consider primary efflorescences today. He wrote many more treatises, relating to different areas of medicine, most of which reached Japan. One century later Keizo Dohi wrote, that Plenck's oeuvre will remain unforgotten in the history of dermatology, for his importance, in general and for the close relation to the development of medicine and dermatology in Japan. A search for Japanese translations of Plenck's books could prove that. Dohi himself wanted to become a surgeon but changed his plans and enrolled in Moriz Kaposi's (1837-1902) department in Vienna as a postgraduate student in 1893. Sifting through Dohi's textbook and papers, the importance of the Hebra-Kaposi School for Japan is again explicitly stated by the Japanese master, who founded the Japanese Dermatological Society in December of 1900 and the disciplines's journal in 1901. The language of publication was German. Dohi's first paper appeared in the Archiv für Dermatologie und Syphilis in 1896, in German. In recent years Austrian dermatology has become influential again in dermatological research after a mid century low. A series of investigators have spent sabbatical years or postgraduate training at the former Hebra-Kaposi Department in Vienna. Their scientific achievements were mainly in the field of immunobiology of the skin. A list of publications and their authors is presented.

    Burnout is considered a major negative outcome of work related distress in social and health care services, especially in nursing. In the present study 179 student nurses in their third year of training and 47 registered nurses, all working in the Austrian province of Salzburg, were examined with the Maslach Burnout Inventory and the Satisfaction With Life Scale. Compared on a regional and national level, burnout scores of student nurses were equal to those of registered nurses and workers in social and nursing professions. The specific stressors of education and training lead to strain comparable to years of professional experience and exposure to stressors. The relatively high level of satisfaction with life in student nurses may be due to specific resources and ways of compensation, that require further examination. Differences between urban and rural districts (with lower burnout scores and higher satisfaction with life sores in rural districts) were strong in student nurses. Compared with international nurse and health care samples, burnout is relatively low in the examined groups. Registered nurses and student nurses in rural districts show the lowest scores of all in emotional exhaustion and depersonalization, respectively.

    Full Text Available Given the economic importance of small and medium sized enterprises (SMEs and their need for strategic sustainability management, this paper examines the concept of Sustainability Balanced Scorecard (SBSC with respect to SMEs. This case study describes the development of an SBSC in a middle-sized Austrian brewery. The existing methods used in SBSC creation were adapted to suit the company’s specific needs. The findings show that when developing an SBSC it is important to take specific SME characteristics into account and apply methods that allow for adaptation to the prevailing conditions, such as strategic management, organizational structure and resources. In the case study special attention was paid to strategy analysis and thereby the creation of a solid basis for the SBSC. Furthermore, the results show SBSC development is not a process of distinct consecutive steps, as it is often suggested in the literature, but rather that it is a complex process marked by iterative steps. Moreover, the paper highlights the supporting factors and challenges experienced. Whereas top management support, the presence of a project team and high employee involvement were identified as key supporting factors, a lack of specific resources and blurry strategy formulation exert negative influence on the development process. The results presented here should help other SMEs in their development of an SBSC. The paper stimulates scientific discourse on sustainability and strategic management by highlighting the relevant supporting factors and challenges.

    Strategies for doping prevention are based on prior identification of opportunities for intervention. There is no current research focusing on the potential role in doping prevention, which might be played by the parents of junior elite athletes. The purpose of this study was to evaluate the knowledge and attitudes toward doping among parents of Austrian junior athletes and to analyze factors potentially influencing these beliefs. In this study, two questionnaires were distributed to 1818 student athletes, each with instructions that these surveys were to be completed by their parents (n(total) = 3636). Parents filled in questionnaires at home without observation. Responses from 883 parents were included in this analysis. Compared to female parents, male parents demonstrated significantly better knowledge about doping and its side effects and were more likely to be influenced by their own sporting careers and amounts of sports activities per week. Parental sex did not demonstrate a significant influence on responses reflecting attitudes toward doping. Additional research is needed to compare these results with young athletes' knowledge and attitudes to determine if and to what degree parental attitudes and beliefs influence the behavior and attitudes of their children.

    At the Sulm River, an Austrian lowland river, an ecologically orientated flood protection project was carried out from 1998-2000. Habitat modeling over a subsequent 3-year monitoring program (2001-2003) helped assess the effects of river bed embankment and of initiating a new meander by constructing a side channel and allowing self-developing side erosion. Hydrodynamic and physical habitat models were combined with fish-ecological methods. The results show a strong influence of riverbed dynamics on the habitat quality and quantity for the juvenile age classes (0+, 1+, 2+) of nase (Chondrostoma nasus), a key fish species of the Sulm River. The morphological conditions modified by floods changed significantly and decreased the amount of weighted usable areas. The primary factor was river bed aggradation, especially along the inner bend of the meander. This was a consequence of the reduced sediment transport capacity due to channel widening in the modeling area. The higher flow velocities and shallower depths, combined with the steeper bank angle, reduced the Weighted Useable Areas (WUAs) of habitats for juvenile nase. The modeling results were evaluated by combining results of mesohabitat-fishing surveys and habitat quality assessments. Both, the modeling and the fishing results demonstrated a reduced suitability of the habitats after the morphological modifications, but the situation was still improved compared to the pre-restoration conditions at the Sulm River.

    On behalf of the Federal Ministry of Agriculture, Forestry, Environment and Water Management (BMLFUW), the National Radon Centre of Austria developed the National Radon Risk Communication Strategy. The superior goal is the reduction of the radon exposure of Austrian citizens as well as the reduction of radon-related lung cancer deaths. Austria, like many other countries, follows the approach to raise awareness and to inform the public to achieve this goal. The presented strategy deals with the question of how radon protection issues can be communicated to the public, existing fears can be reduced and affected people can be motivated to take action (perform a radon test, if necessary, mitigate or install preventive measures in new buildings). The cornerstones of the National Radon Risk Communication Strategy can be summarized as follows: - Definition of communication goals - Identification and categorization of target groups - Development of specific key messages for each of the target groups - Determination of communication channels and assessment of their efficiency - Integration of the radon issue in education and training - Cooperation with relevant organizations and platforms. The communication objectives, target groups and communication paths (and their evaluation) will be discussed during the presentation in detail.

    Full Text Available Runs of homozygosity (ROH are recognized as potential inbreeding measure in studies on humans. Inbreeding coefficients derived from ROH (FROH measure proportion of the genome arranged in long homozygous segments and highly correlate with those derived from pedigree (Fped. From that we assumed that ROH represent an alternative to pedigree inbreeding levels in studies on animals too, because pedigree can be incorrect, incomplete and can not fully explain what happened in meiosis. To confirm our premise we used pedigree and genotype data from 500 Austrian dual purpose Simmental bulls to determine correlation between FROH and Fped. ROH were obtainedusing Fortran 90 soft ware created by the authors. Proportions of genome in ROH were calculated for lengths of ROH of >1, >2, >4, >8 and >16 Mb. Pedigree data were analyzed and inbreeding coefficients for complete pedigree (FpedT and five generations (Fped5 were calculated using ENDOG soft ware. We found low FpedT and Fped5 (means of 1.5% and 0.9% while FROH for segments >1Mb suggested much higher values (9.0% indicating old inbreeding that can not be traced using pedigree. The highest correlations were found between FROH calculated from ROH of length >4Mb and FpedT (0.68 that is consistent with studies on humans. We conclude that inbreeding coefficients derived from ROH are useful for measuring levels of inbreeding in cattle, because ROH are not subject to mistakes as pedigrees and calculations made from those.

    The continuously increasing demands on botanic gardens during the last few decades have led to a huge in increase administration and an urgent need for additional specialized personnel, especially botanists, teachers, database specialists and administrative staff. Instead of meeting these requirements, many botanic gardens are faceing a severe decrease in funding and personnel. Larger gardens provide the opportunity to distribute several tasks to different employees, whereas small gardens are short staffed and often nn by a single curator who has to fulfill all functions. In order to meet actual demands more easily, the Austrian botanic gardens are linked nationally via an active workgroup.This network not only allows the distribution of information but also facilitates the sharing of duties. A listserver speeds up the communication and correspondence within the workgroup, collection priorities and projects (e. g., GSPC) are coordinated, seedbanking becomes decentralized, printedmatters are shared and distributed, etc. Small gardens with only few employees can participate in projects by taking on small-ideally using with their special resources-in order not to fall behind. In addition, there is also an urgent need for international networking by means of plant and seed exchange (Index Semihum), BGCI membership, discussion groups, personal contacts and projects. Mission statements,special marketing strategies for public relations, integrating projects of other workgroup members and adapted public awareness programs are important to focus attention to small gardens and to help them keep alive.

    Full Text Available In an essay titled ‘The Exiled Tongue’ (2002, Nobel Prize winner Imre Kertész develops a genealogy of Holocaust and émigré writing, in which the German language plays an important, albeit contradictory, role. While the German language signified intellectual independence and freedom of self-definition (against one’s roots for Kertész before the Holocaust, he notes (based on his engagement with fellow writer Jean Améry that writing in German created severe difficulties in the post-war era. Using the examples of Hilde Spiel and Friedrich Torberg, this article explores this notion and asks how the loss of language experienced by Holocaust survivors impacted on these two Austrian-Jewish writers. The article argues that, while the works of Spiel and Torberg are haunted by the Shoah, the two writers do not write in the post-Auschwitz language that Kertész delineates in his essays, but are instead shaped by the exile experience of both writers. At the same time though, Kertész’ concept seems to be haunted by exile, as his reception of Jean Améry’s works, which form the basis of his linguistic genealogies, shows an inability to integrate the experience of exile.

    Landsliding resulting from large earthquakes in mountainous terrain presents a substantial hazard and plays an important role in the evolution of mountain ranges. However estimating the scale and effect of landsliding from an individual earthquake prior to its occurrence is difficult. This study presents first order estimates of the scale and effects of coseismic landsliding resulting from a plate boundary earthquake in the South Island of New Zealand. We model an Mw 8.0 earthquake on the Alpine Fault, which has produced large (M 7.8-8.2) earthquakes every 329 ± 68 years over the last 8 ka, with the last earthquake ~ 300 years ago. We suggest that such an earthquake could produce ~ 50,000 ± 20,000 landslides at average densities of 2-9 landslides km- 2 in the area of most intense landsliding. Between 50% and 90% are expected to occur in a 7000 km2 zone between the fault and the main divide of the Southern Alps. Total landslide volume is estimated to be 0.81 + 0.87/- 0.55 km3. In major northern and southern river catchments, total landslide volume is equivalent to up to a century of present-day aseismic denudation measured from suspended sediment yields. This suggests that earthquakes occurring at century-timescales are a major driver of erosion in these regions. In the central Southern Alps, coseismic denudation is equivalent to less than a decade of aseismic denudation, suggesting precipitation and uplift dominate denudation processes. Nevertheless, the estimated scale of coseismic landsliding is considered to be a substantial hazard throughout the entire Southern Alps and is likely to present a substantial issue for post-earthquake response and recovery.

    The integrated stratigraphic, radiocarbon and palynological record from an end-moraine system of the Oglio valley glacier (Italian Alps), propagating a lobe upstream in a lateral reach, provided evidence for a complete cycle of glacial advance, culmination and withdrawal during the Last Glacial Maximum and early Lateglacial. The glacier culminated in the end moraine shortly after 25.8 ± 0.8 ka cal BP, and cleared the valley floor 18.3-17.2 ± 0.3 ka cal BP. A primary paraglacial phase is then recorded by fast progradation of the valley floor. As early as 16.7 ± 0.3 ka cal BP, early stabilization of alluvial fans and lake filling promoted expansion of cembran pine. This is an unprecedented evidence of direct tree response to depletion of paraglacial activity during the early Lateglacial, and also documents the cembran pine survival in the mountain belt of the Italian Alps during the last glaciation. Between 16.1 and 14.6 ± 0.5 ka cal BP, debris cones emplacement points to a moisture increase favouring tree Betula and Pinus sylvestris-mugo. A climate perturbation renewed paraglacial activity. According to cosmogenic ages on glacial deposits and AMS radiocarbon ages from lake records in South-Eastern Alps such phase compares favourably with the Gschnitz stadial and with the oscillations recorded at lakes Ragogna, Längsee and Jeserzersee, most probably forced by the latest freshening phases of the Heinrich Event 1. A further sharp pine rise marks the subsequent onset of Bølling interstadial. The chronology of the Oglio glacier compares closely with major piedmont glaciers on the Central and Eastern Alpine forelands. On the other hand, the results of the present study imply a chronostratigraphic re-assessment of the recent geological mapping of the Central Italian Alps.

    Autoimmune lymphoproliferative syndrome (ALPS) is a rare disorder of disrupted lymphocyte homeostasis. Clinical manifestations of ALPS vary but typically include autoimmune cytopenias, organomegaly, lymphadenopathy, and increased risk of malignancies. A similar spectrum of symptoms may be seen in some patients with Evans syndrome (ES), a hematologic disorder defined by autoimmune destruction of at least 2 hematologic cell types. We hypothesized that a subset of patients diagnosed with ES may have ALPS. We screened 12 children with ES by flow cytometric analysis for CD4-/CD8- (double negative) T cells (DNTs) and with the definitive test for ALPS, defective in vitro Fas-mediated apoptosis. Six of the patients had elevated DNTs, suggestive of ALPS and also had defective Fas-mediated apoptosis. The other 6 patients displayed normal T-cell apoptosis; 5 of whom had normal DNTs, and 1 had a borderline result. Thus, 7 (58%) of 12 patients with ES had elevated DNTs suggestive of ALPS, with functional confirmation in 6 of 7. This suggests that analysis of DNTs may be a sensitive first-line screening test, serving as a marker of patients who should undergo definitive testing for ALPS. Our data further suggest that a number of patients with ES may have ALPS, a novel finding with important therapeutic implications.

At first introduced to solve the strong-CP problem by breaking an additional U(1) Pecci-Quinn symmetry, meanwhile several astrophysical observations hint to the ALPs sector as well. In so called Light-Shining-through-Wall (LSW) experiments the effective diphoton vertex inherent to Axions and ALPs is exploited for direct searches. High power laser beams traversing strong magnetic fields are used to create and annihilate ALPs making them accessible in laboratory setups. In this talk the latest results of the of the OSQAR experiment (CERN) are presented as well as prospects of near future enhancements by the ALPS II (DESY) experiment aiming for an improved sensitivity of 3 orders of magnitude.

    Full Text Available Plus que jamais, l’espace alpin est marqué par le déploiement de flux toujours plus variés, toujours plus puissants, et symétriquement par la multiplication d’initiatives destinées à conforter ou à régénérer l’idée de localité. Quelles spatialités et quelles territorialités travaillent les populations alpines aujourd’hui ? Quelles sont les figures contemporaines de la circulation et des flux, et les figures complémentaires de l’ancrage et de la refondation territoriale ? Voici les questions que cet essai se propose de développer. Ce texte reprend le contenu d’une conférence donnée dans le cadre de la célébration du centenaire de l’Institut de Géographie Alpine. Cette conférence, comme les autres données à cette occasion, avait adopté une forme libre dressant un bilan et des perspectives de la situation alpine. La trace écrite adoptée ici prend alors logiquement la forme d’un essai.More than ever before, the Alps are affected by increasingly varied and powerful flows and equally by the multiplication of initiatives designed to strengthen or regenerate the idea of “locality” (place. What spatialities and what territorialities activate the populations of the Alps today? What are the contemporary figures relating to circulation and flows and the complementary figures concerning spatial “anchoring” or fixity and new territorial foundations? These are the questions that this essay, proposes to develop. This text takes another look at the subject of a lecture given as part of celebrations to mark the centenary of the Institut de Géographie Alpine.

  18. Risk assessment of mountain infrastructure destabilization in the French Alps

    2015-04-01

    In the current context of imbalance of geosystems in connection with the rising air temperature for several decades, high mountain environments are especially affected by the shrinkage of glaciers and the permafrost degradation which can trigger slope movements in the rock slopes (rockfall, rock avalanches) or in superficial deposits (slides, rock glacier rupture, thermokarst). These processes generate a risk of direct destabilization for high mountain infrastructure (huts, cable-cars...) in addition to indirect risks for people and infrastructure located on the path of moving rock masses. We here focus on the direct risk of infrastructure destabilization due to permafrost degradation and/or glacier shrinkage in the French Alps. To help preventing these risks, an inventory of all the infrastructure was carried out with a GIS using different data layers among which the Alpine Permafrost Index Map and inventories of the French Alps glaciers in 2006-2009, 1967-1971 and at the end of the Little Ice Age. 1769 infrastructures have been identified in areas likely characterized by permafrost and/or possibly affected by glacier shrinkage. An index of risk of destabilization has been built to identify and to rank infrastructure at risk. This theoretical risk index includes a characterization of hazards and a diagnosis of the vulnerability. The value of hazard is dependent on passive factors (topography, lithology, geomorphological context...) and on so-considered active factors (thermal state of the permafrost, and changing constraints on slopes related to glacier shrinkage). The diagnosis of vulnerability has meanwhile been established by combining the level of potential damage to the exposed elements with their operational and financial values. The combination of hazard and vulnerability determines a degree of risk of infrastructure destabilization (from low to very high). Field work and several inventories of infrastructure damages were used to validate it. The

    Motivated by the possibility of explaining the 3.5 keV line through dark matter decaying to axion-like particles that subsequently convert to photons, we study ALP-photon conversion for sightlines passing within 50 pc of the galactic centre. Conversion depends on the galactic centre magnetic field which is highly uncertain. For fields at low or mid-range of observational estimates (10–100 μG), no observable signal is possible. For fields at the high range of observational estimates (a pervasive poloidal mG field over the central 150 pc) it is possible to generate sufficient signal to explain recent observations of a 3.5 keV line in the galactic centre. In this scenario, the galactic centre line signal comes predominantly from the region with z>20pc, reconciling the results from the Chandra and XMM-Newton X-ray telescopes. The dark matter to ALP to photon scenario also naturally predicts the non-observation of the 3.5 keV line in stacked galaxy spectra. We further explore predictions for the line flux in galaxies and suggest a set of galaxies that is optimised for observing the 3.5 keV line in this model.

  20. Estimating permafrost distribution in the maritime Southern Alps, New Zealand, based on climatic conditions at rock glacier sites

    2016-02-01

    Full Text Available Alpine permafrost occurrence in maritime climates has received little attention, despite suggestions that permafrost may occur at lower elevations than in continental climates. To assess the spatial and altitudinal limits of permafrost in the maritime Southern Alps, we developed and tested a catchment-scale distributed permafrost estimate. We used logistic regression to identify the relationship between permafrost presence at 280 active and relict rock glacier sites and the independent variables a mean annual air temperature and b potential incoming solar radiation in snow free months. The statistical relationships were subsequently employed to calculate the spatially-distributed probability of permafrost occurrence, using a probability of ≥ 0.6 to delineate the potential permafrost extent. Our results suggest that topoclimatic conditions are favorable for permafrost occurrence in debris-mantled slopes above ~ 2000 m in the central Southern Alps and above ~ 2150 m in the more northern Kaikoura ranges. Considering the well-recognized latitudinal influence on global permafrost occurrences, these altitudinal limits are lower than the limits observed in other mountain regions. We argue that the Southern Alps’ lower distribution limits may exemplify an oceanic influence on global permafrost distribution. Reduced ice-loss due to moderate maritime summer temperature extremes may facilitate the existence of permafrost at lower altitudes than in continental regions at similar latitude. Empirical permafrost distribution models derived in continental climates may consequently be of limited applicability in maritime settings.

    The ALPS collaboration runs a ''Light Shining through a Wall'' (LSW) experiment to search for photon oscillations into ''Weakly Interacting Sub-eV Particles'' (WISPs) often predicted by extensions of the Standard Model. The experiment is set up around a superconducting HERA dipole magnet at the site of DESY. Due to several upgrades of the experiment we are able to place limits on the probability of photon-WISP-photon conversions of a few x 10{sup -25}. These limits result in today's most stringent laboratory constraints on the existence of low mass axion-like particles, hidden photons and minicharged particles. (orig.)

    2010-05-28

    Climate and environmental changes associated with anthropogenic global warming are being increasingly identified in the European Alps, as seen by changes in long-term high-alpine temperature, precipitation, glacier cover and permafrost. In turn, these changes impact on land-surface stability, and lead to increased frequency and magnitude of natural mountain hazards, including rock falls, debris flows, landslides, avalanches and floods. These hazards also impact on infrastructure, and socio-economic and cultural activities in mountain regions. This paper presents two case studies (2003 heatwave, 2005 floods) that demonstrate some of the interlinkages between physical processes and human activity in climatically sensitive alpine regions that are responding to ongoing climate change. Based on this evidence, we outline future implications of climate change on mountain environments and its impact on hazards and hazard management in paraglacial mountain systems.

    Austrian Space Forum: The Austrian Space Forum (OeWF, Österreichisches Weltraum Forum) is a non-profit, citizen-science organization of aerospace specialists and enthusiasts. One of its specialisations is Mars analog research. Analog studies and analog instrument validation supported all planetary surface missions so far [1] and are considered as an effective tool to prepare for future missions to Mars [2,3,4,5,6,7]. Since 2006, OeWF has conducted 11 Mars analog field campaigns in diverse locations that represented: 1) average current Mars conditions (the Mars Desert Research Station (MDRS) in Utah in 2006 [8] and the Northern Sahara near Erfoud, Morocco in 2013 [9]); 2) the early and wet Mars (analog site of Rio Tinto Spain in 2011 [10]); and 3) subsurface exploration (Dachstein Ice Caves in 2012). During these campaigns, 68 experiments and major engineering tests were performed, whichwere mostly focused on astrobiology, robotics, human factors, geoscience and spacesuit operations. Major assets of OeWF include two advanced spacesuit simulators Aouda [11], an increasingly evolving Mission Support Center, a dedicated Remote Science Support team [12], and a growing set of Standard Operating Procedures defining major workflows within a mission team. The spacesuit simulators were operated by a total of 18 analog astronauts, who were selected and trained during a >6 month program. Total EVA time is nearly 600 hours, leading to a significant experience in analog field simulations. AMADEE-15: The mission took place between August 2nd and 14th 2015 at the Kaunertal Glacier in Tyrol, Austria. This glacier was selected as a study site because of its accessibility and high number of micro-landscapes analogous to those expected on Mars in locations where abundant water ice is present. As such it is considered a first-tier Mars analog [13]. The Base station was located at N 46.86320, E 10.71401 at 2800 masl, the highest reached location was on elevation of 2887 m. Eleven

  6. Brooks Range and eastern Alps: a tectonic comparison

    A comparison of the tectonic evolution of the Brooks Range (BR) and the Eastern Alps (EA) reveals a remarkable parallelism. Both of these Mesozoic-Cenozoic orogenic belts are underlain by sialic crust formed in an earlier Paleozoic orogenic cycle. The old basement is revealed in major tectonic windows: the Tauern Fenster (EA) and the Doonerak Window-Schwatka Mountains (BR) - which are unconformably overlapped by transgressive, neritic marine clastic to carbonate successions - the Permo-Triassic through Hochstegenkalk sequence (EA), and the Kekiktuk-Kayak-Lisburne sequence (BR). These successions are passive-margin sequences that pass southward, in palinspastically restored cross sections, to synchronous deep-water facies deposited on ophiolitic basement - Bunderschiefer on Triassic-Jurassic ophiolites (EA) and Kuna facies or Etivluk sequence on upper Paleozoic ophiolites (BR). Onset of subduction-collision is marked by olistostromal facies - Cretaceous wildflysch (EA) and Jura-Cretaceous Okpikruak Formation (BR) - and the development of major flysch-molasse successions in the foreland basins of the collisional fold and thrust belts. Important major contrasts between these two mountain ranges reside in their colliding blocks and their post-orogenic histories. Alpine orogenesis was driven by continent-continent collision, closing out a young, narrow ocean, whereas Brooks Range deformation appears to have originated by arc-continent collision, closing out an older, broad (.)ocean. Younger Cenozoic deformation is extensional and strike-slip in the Eastern Alps, producing disjunctive basins, but Cenozoic deformation in the Brooks Range is diverse and includes compression in the east and extension in the far west.

  7. Tracer and hydrometric techniques to determine the contribution of glacier melt to a proglacial stream in the Ötztal Alps (Tyrol, Austria)

    Glaciers are important seasonal water contributors in many mountainous landscapes. For water resources management it is important to know about the timing and amount of released glacier melt water, especially in downstream regions where the water is needed (hydropower, drinking water) or where it represents a potential risk (drought, flood). Seasonal availability of melt water is strongly dependent on boundary layer atmospheric processes and becomes even more relevant in a changing climate. Environmental tracers are a useful tool in the assessment of snow and ice water resources, because they provide information about the sources, flow paths and traveling times of water contributing to streamflow at the catchment scale. Previously, high-elevation tracer studies throughout the Alps have been scarce as they require intense field work in remote areas. However, hydrometric and meteorological measurements combined with tracer analyses help to unravel streamflow composition and improve the understanding of hydroclimatological processes. On top of that, empirical studies are necessary to parameterize and validate hydrological models in more process-oriented ways, rather than comparing total measured and simulated runoff only. In the present study three approaches are applied to derive glacier melt contributions to a proglacial stream at the seasonal scale and to identify their individual advances and limitations. Tracers used for each approach are (1) electrical conductivity, (2) stable isotopes of water and (3) heavy metals. The field work was conducted during the summer of 2015 in the glaciated (35%) high-elevation catchment of the Hochjochbach, a small sub-basin (17 km²) of the Ötztaler Ache river in the Austrian Alps, ranging from 2400 to 3500 m.a.s.l. in elevation. Hydroclimatological data was provided by an automatic weather station and a gauging station equipped with a pressure transducer.

    The new Austrian tunneling method (NATM) is widely applied in design and construction of under-ground engineering projects. When the type and distribution of unfavorable geological bodies (UGBs) associated with their influences on geoengineering are complicated or unfortunately are overlooked, we should pay more attentions to internal features of rocks grades IV and V (even in local but mostly controlling zones). With increasing attentions to the characteristics, mechanism and influences of en-gineering construction-triggered geohazards, it is crucial to fully understand the disturbance of these geohazards on project construction. A reasonable determination method in construction procedure, i.e. the shape of working face, the type of engineering support and the choice of feasible procedure, should be considered in order to mitigate the construction-triggered geohazards. Due to their high sensitivity to groundwater and in-situ stress, various UGBs exhibit hysteretic nature and failure modes. To give a complete understanding on the internal causes, the emphasis on advanced comprehensive geological forecasting and overall reinforcement treatment is therefore of more practical significance. Compre-hensive evaluation of influential factors, identification of UGB, and measures of discontinuity dynamic controlling comprises the geoengineering condition evaluation and dynamic controlling method. In a case of a cut slope, the variations of UGBs and the impacts of key environmental factors are presented, where more severe construction-triggered geohazards emerged in construction stage than those pre-dicted in design and field investigation stages. As a result, the weight ratios of different influential factors with respect to field investigation, design and construction are obtained.

    The Austrian RADiation monitoring network (ARAD) has been established to advance the national climate monitoring and to support satellite retrieval, atmospheric modelling and solar energy techniques development. Measurements cover the downwelling solar and thermal infrared radiation using instruments according to Baseline Surface Radiation Network (BSRN) standards. A unique feature of ARAD is its vertical dimension of five stations, covering an air column between about 200 m a.s.l. (Vienna) and 3100 m a.s.l. (BSRN site Sonnblick). The contribution outlines the aims and scopes of ARAD, its measurement and calibration standards, methods, strategies and station locations. ARAD network operation uses innovative data processing for quality assurance and quality control, applying manual and automated control algorithms. A combined uncertainty estimate for the broadband shortwave radiation fluxes at all five ARAD stations indicates that accuracies range from 1.5 to 23 %. If a directional response error of the pyranometers and the temperature response of the instruments and the data acquisition system (DAQ) is corrected, this expanded uncertainty reduces to 1.4 to 5.2 %. Thus, for large signals (global: 1000 W m-2, diffuse: 500 W m-2) BSRN target accuracies are met or closely met for 70 % of valid measurements at the ARAD stations after this correction. For small signals (50 W m-2), the targets are not achieved as a result of uncertainties associated with the DAQ or the instrument sensitivities. Additional accuracy gains can be achieved in future by additional measurements and corrections. However, for the measurement of direct solar radiation improved instrument accuracy is needed. ARAD could serve as a powerful example for establishing state-of-the-art radiation monitoring at the national level with a multiple-purpose approach. Instrumentation, guidelines and tools (such as the data quality control) developed within ARAD are best practices which could be adopted in other

  10. Quasi-dynamic Material Flow Analysis applied to the Austrian Phosphorus cycle

    2013-04-01

    Phosphorus (P) is one of the key elements that sustain life on earth and that allow achieving the current high levels of food production worldwide. It is a non-renewable resource, without any existing substitute. Because of its current dissipative use by mankind and to its very slow geochemical cycle, this resource is rapidly depleting and it is strongly connected to the problem of ensuring food security. Moreover P is also associated to important environmental problems. Its extraction often generates hazardous wastes, while its accumulation in water bodies can lead to eutrophication, with consequent severe ecological damages. It is therefore necessary to analyze and understand in detail the system of P, in regard to its use and management, to identify the processes that should be targeted in order to reduce the overall consumption of this resource. This work aims at establishing a generic quasi-dynamic model, which describes the Austrian P-budget and which allows investigating the trends of P use in the past, but also selected future scenarios. Given the importance of P throughout the whole anthropogenic metabolism, the model is based on a comprehensive system that encompasses several economic sectors, from agriculture and animal husbandry to industry, consumption and waste and wastewater treatment. Furthermore it includes the hydrosphere, to assess the losses of P into water bodies, due to the importance of eutrophication problems. The methodology applied is Material Flow Analysis (MFA), which is a systemic approach to assess and balance the stocks and flows of a material within a system defined in space and time. Moreover the model is integrated in the software STAN, a freeware tailor-made for MFA. Particular attention is paid to the characteristics and the quality of the data, in order to include data uncertainty and error propagation in the dynamic balance.

    More than 2,600 relict rock glaciers are known in the Austrian Alps but the knowledge of their hydraulic properties is severely limited. The relict Schöneben Rock Glacier (Niedere Tauern Range, Austria), with an extension of 0.17 km2, was investigated based on spring data (2006-2014) and seismic refraction survey. Spring-discharge hydrographs and natural and artificial tracer data suggest a heterogeneous aquifer with a layered internal structure for the relict rock glacier. The discharge behavior exhibits a fast and a delayed flow component. The spring discharge responds to recharge events within a few hours but a mean residence time of several months can also be observed. The internal structure of the rock glacier (up to several tens of meters thick) consists of: an upper blocky layer with a few meters of thickness, which lacks fine-grained sediments; a main middle layer with coarse and finer-grained sediments, allowing for fast flow; and an approximately 10-m-thick basal till layer as the main aquifer body responsible for the base flow. The base-flow component is controlled by (fine) sandy to silty sediments with low hydraulic conductivity and high storage capacity, exhibiting a difference in hydraulic conductivity to the upper layer of about three orders of magnitude. The high storage capacity of relict rock glaciers has an impact on water resources management in alpine catchments and potentially regulates the risk of natural hazards such as floods and related debris flows. Thus, the results highlight the importance of such aquifer systems in alpine catchments.

Four-hundred and forty‑one serological and 198 renal samples from red deer, roe deer and chamois collected in the Province of Sondrio were analysed using the microscopic agglutination test and histopathologic examination. Positive serological findings were found only in 15 red deer and 19 positive serologic reactions were recorded. The most frequent serovars were Bratislava and Grippotyphosa, followed by Pomona, Hardjo and Copenhagheni. Twenty-two per cent of renal samples from seropositive red deer were affected by mild to moderate multifocal chronic lymphoplasmacytic and fibrosing tubulo-interstitial nephritis, mainly involving the cortical parenchyma. In this study, antibodies to Leptospira spp. were infrequent in wild ruminants, and only red deer seemed to be sensitive to the infection. Given the low presence and the fact that there was no record of Leptospira spp. infections in cattle, sheep, goats and also hunters in area during the study period, wild ruminants in Alpine environments cannot be considered as reservoirs or important sources of Leptospira spp. infection for humans or domestic animals.

  18. Assessment of the thermal and dynamic reaction scenarios of different permafrost typologies in the European Alps: A PermaNET initiative

    2009-04-01

    High altitude and high latitude regions are generally recognized as being particularly sensitive to the effects of the ongoing climate change. A large part of permafrost in the European Alps for instance is at or close to melting conditions and is therefore very sensitive to degradation caused by atmospheric warming. Knowledge regarding permafrost distribution and its climatologically driven dynamics in the entire European Alps is still far from being complete. The new European Union co-funded project "PermaNET - Permafrost long-term monitoring network" (launched in July 2008) attempts to close some of these major gaps in permafrost knowledge (www.permanet-alpinespace.eu). One work package of PermaNET focuses on the assessment of the relationship between permafrost and climate change. In it, one action is concerned with the assessment of the thermal and dynamic reaction scenarios of different permafrost typologies in the European Alps. Research in this action is focussing on the relationship between measured climate data and observed permafrost reaction using available datasets collected during the last decades in the European Alps. Such datasets include ground temperature measurements (at the surface and in boreholes), rock glacier displacements or observations on mass movement events that were initiated in permafrost environments (e.g. rock falls). These established relationships in combination with calculated data from climate scenario modelling will form the basis for model simulations and estimations regarding changes in permafrost distribution (vertically and horizontally), in the active layer thickness, in the rates of rock glacier displacement, etc. Study sites for this action are located in Austria (Mt. Sonnblick, Central Schober Mountains, Dösen Valley, Mt. Hochreichart, Schrank Cirque), in Italy (Cime Bianche Pass, Matterhorn SW ridge, Valtournenche, Aosta Valley Region, Val di Genova and Val d'Amola in the Adamello-Presanella Group), in Switzerland

    Full Text Available The work examines the seasonality and large-scale atmospheric circulation patterns of debris flows in the Trentino-Alto Adige region (Eastern Italian Alps. Analysis is based on classification algorithms applied on a uniquely dense archive of debris flows and hourly rain gauge precipitation series covering the period 2000–2009. Results highlight the seasonal and synoptic forcing patterns linked to debris flows in the study area. Summer and fall season account for 92% of the debris flows in the record, while atmospheric circulation characterized by Zonal West, Mixed and Meridional South, Southeast patterns account for 80%. Both seasonal and circulation patterns exhibit geographical preference. In the case of seasonality, there is a strong north–south separation of summer–fall dominance while spatial distribution of dominant circulation patterns exhibits clustering, with both Zonal West and Mixed prevailing in the northwest and central east part of the region, while the southern part relates to Meridional South, Southeast pattern. Seasonal and synoptic pattern dependence is pronounced also on the debris flow triggering rainfall properties. Examination of rainfall intensity–duration thresholds derived for different data classes (according to season and synoptic pattern revealed a distinct variability in estimated thresholds. These findings imply a certain control on debris-flow events and can therefore be used to improve existing alert systems.

    A comparison between the Mesopotamian Law (Codex Ur-nammu) and the Austrian Penal Code reveals the long-sightedness of the founder of the 3rd dynasty from Ur, called Ur-nammu. It seems extremely remarkable that at those remote times (3rd Millenium B. C.) body injuries were satisfied by simple money-penalties. The Codex Ur-nammu therefore not only represents on exceedingly piece of work from the historical point of view but also from the point of view from Legal Medicine.

    In 2016, a new university hospital merged from three former independent Austrian hospitals started its operation. This paper presents a process model developed to coordinate the IT migration after the merger, using five phases to meet the requirements of the specific setting. A methodological mix of interviews, surveys and workshops was applied during the IT migration process. High stakeholder participation and a transparent methodical approach led to a broad agreement on success factors, migration objectives, and evaluation results. Thus, acceptance for the finally selected migration scenario was very high among employees, which is known to be crucial for the success of migration projects.

    Objective:To explore the role and significance of the joint detection of serum alkaline phosphatase (ALP) and osteocalcin in prostate cancer bone metastases.Methods:A total of 87 cases of prostate cancer patients were diagnosed by radionuclide bone imaging, and 51 cases of them were included in the bone metastases group, while the other 36 cases were selected as the non-metastases group. Serum levels of ALP and osteocalcin of all patients were detected. The sensitivity, specificity, accuracy, likelihood ratio and the predictive value of patients in the two groups were analyzed. The sensitivity and specificity of the combined detection of ALP and osteocalcin and their expression levels in different bone metastases degrees were analyzed.Results:Serum ALP and osteocalcin levels of patients in metastases group were higher than those in non-metastases group and normal control group. In non-metastases group, the ALP level was higher than that in normal control group, while its osteocalcin level was lower than that in control group (P<0.05); The sensitivities of ALP and osteocalcin were 77.2% and 70.6%, respectively, and their specificities were 61.1% and 54.6%, respectively. The sensitivity and specificity became 93.3% and 82.33% in combined detection of ALP and osteocalcin, which was significantly higher than the single detection (P<0.05). The expression levels of ALP and osteocalcin increased with the increase of the metastases degrees (P<0.05). Conclusions:Combined detection of ALP and osteocalcin can be used in the early diagnosis of prostate cancer with improved diagnostic efficiency.

    The recent detection of the cosmic microwave background polarimeter experiment BICEP2 of tensor fluctuations in the B-mode power spectrum basically excludes all plausible axion models where its decay constant is above 10{sup 13} GeV. Moreover, there are strong theoretical, astrophysical, and cosmological motivations for models involving, in addition to the axion, also axion-like particles (ALPs), with decay constants in the intermediate scale range, between 10{sup 9} GeV and 10{sup 13} GeV. Here, we present a general analysis of models with an axion and further ALPs and derive bounds on the relative size of the axion and ALP photon (and electron) coupling. We discuss what we can learn from measurements of the axion and ALP photon couplings about the fundamental parameters of the underlying ultraviolet completion of the theory. For the latter we consider extensions of the Standard Model in which the axion and the ALP(s) appear as pseudo Nambu-Goldstone bosons from the breaking of global chiral U(1) (Peccei-Quinn (PQ)) symmetries, occuring accidentally as low energy remnants from exact discrete symmetries. In such models, the axion and the further ALP are protected from disastrous explicit symmetry breaking effects due to Planck-scale suppressed operators. The scenarios considered exploit heavy right handed neutrinos getting their mass via PQ symmetry breaking and thus explain the small mass of the active neutrinos via a seesaw relation between the electroweak and an intermediate PQ symmetry breaking scale. We show some models that can accommodate simultaneously an axion dark matter candidate, an ALP explaining the anomalous transparency of the universe for γ-rays, and an ALP explaining the recently reported 3.55 keV gamma line from galaxies and clusters of galaxies, if the respective decay constants are of intermediate scale.

    A multidisciplinary approach provides data from natural, historical, and instrumental time series, for the study of potential effects of climatic changes on alpine floods outside the known range of extreme events. The research focuses on the densely populated Bernese Alps, which are a true "hot spot" of hydrological risk. For the reconstruction of climate variability and floods, interdecadal-resolution alluvial delta plain records were examined. The multi-proxy approach affords insight into alpine flood dynamics of mid-scale catchments during the last three millennia. Spectral analysis of the geochemical and pollen time series records and climate proxies (δ14C, δ18O isotopes from the Greenland ice, NAO) evidence similar periodicities of 60, 85, 105 and 200 yrs. Thus, the mechanisms of the flood processes are strongly influenced by the North Atlantic dynamics and solar activity. The proxies indicate that cooler climate pulses and transitions from cool to warm climate pulses were an important external driving force of floods. This hypothesis is supported by the reconstructed floods of the Aare and Lütschine rivers from local documentary sources during the last 500 yrs. Flood periods inferred from sedimentary archives (flood layers, geochemical proxies and shifts of river channel) were calibrated by local documentary flood records and compared with the pattern of settlement on flood prone landforms. The generated data series shows also a good correlation with climate proxies, such as the annual temperatures of Europe (Luterbacher et al., 2004), tree ring based summer temperatures of Central Europe (Büntgen et al., 2011) and total solar irradiance according to the model of Steinhilber et al. (2009). With regard to the last two centuries flood magnitude and frequencies (exact dating) as well as driving mechanisms were reconstructed with more precision. Furthermore, a summer flood index of Switzerland (INU) based on damages recorded from 1800 to 2008 AD was performed

Polymorphism of protein markers was determined in selected genotypes originating from seven populations (Scots pine and six populations (Austrian pine. Analysis of protein markers was performed using two statistical methods, NTSYS and correspondence analysis. Both methods give the same arrangement of the analyzed populations, whereby, because of a different view of genetic distances, they can and should be combined, enabling easier and more precise understanding of mutual relationships of the observation units.

  11. Avalanche risk assessment for mountain roads - a comparison of case studies from Iceland and the Alps

    ðarvegur between Siglufjörður and Straumnes in northern Iceland (Wastl et al. 2008). The total length of the public road network in Iceland is ca. 13000 km, mostly low-volume roads outside built-up areas. Almost 10500 km of these roads are open all year. Substantial parts of the public road network e.g. in central northern Iceland, northwestern and eastern Iceland lie in alpine mountain areas and are affected by characteristic natural hazard processes. Though the resulting road maintenance costs are considerable there is no general overview of the natural hazard situation up to now. The case study for Siglufjarðarvegur shows that a regional scale risk based approach is practical to determine, analyse and assess the natural hazard situation on mountain roads in Iceland and helps to assign priorities in following detailed investigations and the planning of measures. Thus road sections of a high risk level which should be given priority for possible protective measures can be identified and distinguished from areas of avalanche hazard where the collective avalanche death risk is low and acceptable according to international practice. The calculated risks can further be reduced by measures like temporary closing of parts of the road, which can bring the risk to an acceptable level almost everywhere in the investigated road section. This requires, however, a systematic monitoring of the development of the natural hazard situation along the road. The cumulative risk for the investigated section of Siglufjarðarvegur, for the case that no measures of avalanche prevention or control or temporary closing of the road are taken, agrees well with values determined for mountain roads in the Alps.

    The 8.2 ka event has been identified as a widespread climate excursion affecting most of the Northern Hemisphere. High-resolution records from ice cores and speleothems constrain the chronology of this event to between 8.21±0.02 and 8.08±0.03 ka BP (Vinther et al. 2006, Cheng et al. 2009). A distinctive asymmetrical pattern in d18O is consistent with modelling results suggesting rapid input of freshwater into the northern Atlantic due to catastrophic drainage of ice-marginal lakes (LeGrande et al., 2008). Despite an increasing amount of data, the regional expression of this event is still poorly understood. Here, we present a new speleothem record from Gasselhöhle in the Northern Calcareous Alps, Austria. The 205 mm-long GAS19 stalagmite was analysed at high resolution for stable isotopes (100 µm) and trace elements (~10-15 µm; continuous LA-ICPMS profiles). Twelve individual MC-ICP-MS U/Th ages underline an annual growth rate of ca. 60 µm during the Early Holocene. The d18O averages -8.9‰, only slightly more depleted than modern carbonate precipitates from the same cave chamber. The 8.2 ka event is marked in GAS19 by a ca. 1‰ excursion with a minimum value of -9.9‰. Largely invariant trace element concentrations (e.g. Mg, U, Sr, Ba) indicate essentially no changes in the local hydrological regime and therefore support the hypothesis of a temperature-dominated signal. The proximity to the lacustrine isotope record from Mondsee (eg. Lauterbach et al. 2011) opens new perspectives for the interpretation of the oxygen isotope signal using two archives at different elevations. Moreover, several coeval speleothem records are available across the Eastern Alps fostering a spatial comparison of the proxy signals associated with this event. Cheng, H. et al.

    Sustainability of bioenergy is often indicated by the neutrality of emissions at the conversion site while the feedstock production site is assumed to be carbon neutral. Recent research shows that sustainability of bioenergy systems starts with feedstock management. Even if sustainable forest management is applied, different management types can impact ecosystem services substantially. This study examines different sustainable forest management systems together with an optimal planning of green-field bioenergy plants in the Alps. Two models - the biophysical global forest model (G4M) and a techno-economic engineering model for optimizing renewable energy systems (BeWhere) are implemented. G4M is applied in a forward looking manner in order to provide information on the forest under different management scenarios: (1) managing the forest for maximizing the carbon sequestration; or (2) managing the forest for maximizing the harvestable wood amount for bioenergy production. The results from the forest modelling are then picked up by the engineering model BeWhere, which optimizes the bioenergy production in terms of energy demand (power and heat demand by population) and supply (wood harvesting potentials), feedstock harvesting and transport costs, the location and capacity of the bioenergy plant as well as the energy distribution logistics with respect to heat and electricity (e.g. considering existing grids for electricity or district heating etc.). First results highlight the importance of considering ecosystem services under different scenarios and in a geographically explicit manner. While aiming at producing the same amount of bioenergy under both forest management scenarios, it turns out that in scenario (1) a substantially larger area (distributed across the Alps) will need to be used for producing (and harvesting) the necessary amount of feedstock than under scenario (2). This result clearly shows that scenario (2) has to be seen as an "intensification

    The Austrian RADiation monitoring network (ARAD) has been established to advance the national climate monitoring and to support satellite retrieval, atmospheric modeling and the development of solar energy techniques. Measurements cover the downward solar and thermal infrared radiation using instruments according to Baseline Surface Radiation Network (BSRN) standards. A unique feature of ARAD is its vertical dimension of five stations, covering an altitude range between about 200 m a.s.l (Vienna) and 3100 m a.s.l. (BSRN site Sonnblick). The paper outlines the aims and scopes of ARAD, its measurement and calibration standards, methods, strategies and station locations. ARAD network operation uses innovative data processing for quality assurance and quality control, utilizing manual and automated control algorithms. A combined uncertainty estimate for the broadband shortwave radiation fluxes at all five ARAD stations, using the methodology specified by the Guide to the Expression of Uncertainty in Measurement indicates that relative accuracies range from 1.5 to 2.9 % for large signals (global, direct: 1000 W m-2, diffuse: 500 W m-2) and from 1.7 to 23 % (or 0.9 to 11.5 W m-2) for small signals (50 W m-2) (expanded uncertainties corresponding to the 95 % confidence level). If the directional response error of the pyranometers and the temperature response of the instruments and the data acquisition system (DAQ) are corrected, this expanded uncertainty reduces to 1.4 to 2.8 % for large signals and to 1.7 to 5.2 % (or 0.9-2.6 W m-2) for small signals. Thus, for large signals of global and diffuse radiation, BSRN target accuracies are met or nearly met (missed by less than 0.2 percentage points, pps) for 70 % of the ARAD measurements after this correction. For small signals of direct radiation, BSRN targets are achieved at two sites and nearly met (also missed by less than 0.2 pps) at the other sites. For small signals of global and diffuse radiation, targets are achieved

    2016-04-01

    This contribution deals with the first comprehensive analysis of GNSS derived surface velocities computed within an observation network of about 100 stations covering the whole Austrian territory and parts of the neighbouring countries. Coordinate time series are available now, spanning a period of 5 years (2010.0-2015.0) for one focus area in East Austria and one and a half year (2013.5-2015.0) for the remaining part of the tracking network. In principle the data series are stemming from two different GNSS campaigns. The former was set up to investigate intra plate tectonic movements within the framework of the project ALPAACT (seismological and geodetic monitoring of ALpine-PAnnonian ACtive Tectonics), the latter was designed to support a number of various requests, e.g. derivation of GNSS derived water vapour fields, but also to expand the foresaid tectonic studies. In addition the activities within the ALPAACT project supplement the educational initiative SHOOLS & QUAKES, where scholars contribute to seismological research. For the whole period of the processed coordinate time series daily solutions have been computed by means of the Bernese software. The processed coordinate time series are tied to the global reference frame ITRF2000 as well as to the frame ITRF2008. Due to the transition of the reference from ITRF2000 to ITRF2008 within the processing period, but also due to updates of the Bernese software from version 5.0 to 5.2 the time series were initially not fully consistent and have to be re-aligned to a common frame. So the goal of this investigation is to derive a nationwide consistent horizontal motion field on base of GNSS reference station data within the ITRF2008 frame, but also with respect to the Eurasian plate. In this presentation we focus on the set-up of the coordinate time series and on the problem of frame alignment. Special attention is also paid to the separation into linear and periodic motion signals, originating from tectonic or non

    Full Text Available In the article the mutual influence of folk theatre, Austrian Singspiel and Viennese opera in the genres of comic opera, operetta and drama performances involving music, singing and dancing is studied. The powerful influence of Italian and French opera schools, as well as the Italian Commedia Dell'arte led to the flourishing of music and theatre art in Austria: opera buffa (A. Salieri, Ch. W. Glück, J. Haydn, W. A. Mozart, fairy-tale comedies of F. Raimund and satirical dramas of Nestroy. Their game-like nature finds its expression in musical turns, satirical songs and duets. Viennese dance operetta has absorbed the traditions of Viennese popular comedy and comic opera. Recitative, vocal music and folk dances were the key elements of operettas (J. Strauss junior, F. von Suppe, K. Millöcker, K. Zeller, F. Lehar. The music and the game in Austria are the results of theatralization of life: the life turns into something like art. Austrian culture, which is addressed directly to the human being and short of complex philosophical musings and speculative schemes, has genetically built-in playful, musical and theatrical basis, as well as German. Strongly-pronounced playful and musical source as an important national component of the culture, its code, determine its highly fictitious character (staginess and integrity (both genre and intermediately, thereby maintain its special status in the European culture.

    We identified 17 BRCA1 mutations in 86 Austrian breast and ovarian cancer families (20%) that were screened for mutations by denaturing high-performance liquid chromatography (DHPLC) and the protein truncation test (PTT). Eleven distinct mutations were detected, 4 of them (962del4, 2795del4, 3135del4 and L3376stop) not previously reported in families of non-Austrian origin. In addition, 6 rare missense mutations (allele frequency Cys61Gly (3 times) 5382insC (2 times) and Q1806stop (2 times). Haplotype analysis of the 4 recurrent mutations suggested a common ancestor for each of these. Thirty-four breast cancer cases from 17 families with BRCA1 mutations were further analyzed. We observed a low median age of onset (39.5 years). Sixty-eight percent of all BRCA1 breast cancer cases had negative axillary lymph nodes. This group showed a significant prevalence of a negative estrogen and progesterone receptor status and stage I tumors compared with an age-related, node-negative control group. The prevalence of grade III tumors was marginally significant. Survival analysis either with a control group matched for age (within 5 years), grade, histologic subtype and estrogen receptor status, or with an age-related, node-negative comparison group, showed no statistical difference.

    An essential design requirement of the ALPS-II experiment is the efficient detection of single photons with a very low instrumental background of 10 {mu}Hz. In 2011 the ALPS collaboration started to set up a TES detector (Transition-Edge Sensor) for ALPS-II, the second phase of the experiment. Since mid of 2013 the setup is ready for characterization in the ALPS laboratory: an ADR cryostat (Adiabatic Demagnetization Refrigerator) as millikelvin environment, a low noise SQUID (Superconducting Quantum Interference Device) with electronics for read-out and a fiber-coupled high-efficient TES for near-infrared photons as sensor. First measurements have shown a good discrimination between noise and 1064 nm signals.

    Between 1995 and 1999, several cattle of a group of 80 heifers died acutely on a pasture in the Swiss Alps. The animals were Found dead between July 9th and 15th eachyear. Only 1 animal was examined on post-mortem, and no significant lesions were found. Aconitum vulpera, A napellus, and Delphinium elatum were identified in the pasture. The presence of diterpenoid alkaloid-containing plants in the pasture, the rapid death of the animals, and the lack of pathologic lesions suggested diterpenoid alkaloid toxicosis as a cause of death. A multiresidue alkaloid screen using gas chromatography with a mass spectrometric detector was employed on rumen, abomasal, small intestine, and cecal contents from the I heifer. Deltaline, deltamine, and lycoctonine were identified. Aconitine was found in all gastrointestinal samples using a sensitive and highly specific liquid chromatography/mass spectrometry methodology for aconitine analysis. The findings ofditerpenoid alkaloids in the gastrointestinal contents confirmed exposure to Delphinium and Aconitum spp, possibly resulting in sudden death.

    Risk assessment of snow avalanches is mostly related to weather conditions and snow cover. However a robust risk validation requires to identify all avalanches occurring, in order to compare predictions to real effects. For this purpose on December 2009 we installed a temporary 4-element, small aperture (100 m), infrasound array in the Alps. The array has been deployed south of Mt. Rosa, at an elevation of 2000 m a.s.l. in the valley of Gressoney, where natural avalanches are expected and triggered ones are regularly programmed. The array consists into 4 absolute pressure transducers with a sensitivity of 0.01 Pa in the 0.1-50 Hz frequency band and a 7 channel Guralp CMG-DM24 A/D converter, sampling at 100 Hz. Timing is achieved with a GPS receiver. The array is completely buried in snow. Gel cell batteries and 200 W solar panels provide the array power requirements (~3 W) and should allow a continuous operation during the winter season. A multi-channel semblance is carried out on the continuous data set as a function of slowness, back-azimuth and frequency of recorded infrasound in order to detect all avalanches occurring from the back-ground signal, strongly affected by microbarom and mountain induced gravity waves. This pilot experiment in Italy will allow to verify the efficiency of the system, and might represent an important validation to modeled avalanches activity during this winter season.

    It is generally accepted that certain astronomical and cosmological observations can be explained by invoking the concepts of Dark Matter and Dark Energy (DM/DE). Applying straightforward extensions of the Standard Model to DM/DE, results in scalar fi?elds and predictions of particles generation via photo-magnetic coupling . Under the right conditions, these particles should be observable in earth-bound laboratory settings. Although many attempts have been made to observe these particles, none have succeeded. Heretofore, most searches have focused on detecting multi-GeV Dark Matter WIMPS. Recently, however, searches have been conducted in the lighter dark matter, sub-eV, WISP mass range. By comparison, little has been done to search for dark energy particles. The ALPs-Chameleon Experiments Stations (ACES) program, described herein, proposes a compact station that would search for both dark sector particles. Finally, it is noted that both "species" of particles - dark energy and dark matter - could be generate...

    The advanced Large-Area Plastic Scintillator (ALPS) Project at Pacific Northwest National Laboratory investigated possible technological avenues for substantially advancing the state-of-the-art in gamma-ray detection via large-area plastic scintillators. The three predominant themes of these investigations comprised the following: * Maximizing light collection efficiency from a single large-area sheet of plastic scintillator, and optimizing hardware event trigger definition to retain detection efficiency while exploiting the power of coincidence to suppress single-PMT "dark current" background; * Utilizing anti-Compton vetoing and supplementary spectral information from a co-located secondary, or "Back" detector, to both (1) minimize Compton background in the low-energy portion of the "Front" scintillator's pulse-height spectrum, and (2) sharpen the statistical accuracy of the front detector's low-energy response prediction as impelmented in suitable energy-windowing algorithms; and * Investigating alternative materials to enhance the intrinsic gamma-ray detection efficiency of plastic-based sensors.

    The ultimate goal for surface modifications in bone implants is to achieve biologically active surface able to control and trigger specific tissue response. In this study was evaluated the effects of organic compound, derived from extracellular matrix, involved in tissue mineralization. Alkaline phosphatase (ALP) plays a fundamental role in bone mineralization concurrently with collagen, the main organic components of bones. Electrospray deposition (ESD) was used to coat titanium disks with ALP and collagen at room temperature. To verify the synergistic role of ALP and collagen different conformations of coatings (mixed and layered) were obtained and their mineralization capacity was tested in vitro. The mineralization tests indicated the fundamental role of collagen to increase ALP coating retention. Analyses indicated that the coating conformation has a role; in fact the mixed group showed improved ALP retention, enzymatic activity and unique mineralized surface morphology. ESD demonstrated to be a successful method to deposit organic molecules preserving their properties as indicated by the in vitro results. These findings proved the synergistic effect of ALP and collagen in inducing mineralization offering an intriguing coating constituent for medical device that aim to trigger surface mineralization such as bone implants.

    The recent detection of the cosmic microwave background polarimeter experiment BICEP2 of tensor fluctuations in the B-mode power spectrum basically excludes all plausible axion models where its decay constant is above $10^{13}$ GeV. Moreover, there are strong theoretical, astrophysical, and cosmological motivations for models involving, in addition to the axion, also axion-like particles (ALPs), with decay constants in the intermediate scale range, between $10^9$ GeV and $10^{13}$ GeV. Here, we present a general analysis of models with an axion and further ALPs and derive bounds on the relative size of the axion and ALP photon (and electron) coupling. We discuss what we can learn from measurements of the axion and ALP photon couplings about the fundamental parameters of the underlying ultraviolet completion of the theory. For the latter we consider extensions of the Standard Model in which the axion and the ALP(s) appear as pseudo Nambu-Goldstone bosons from the breaking of global chiral $U(1)$ (Peccei-Quinn ...

    In autoimmune/lymphoproliferative syndrome (ALPS), defective Fas death receptor function causes lymphadenomegaly/splenomegaly, the expansion of T-cell receptor αβ(+) CD4/CD8 double-negative T cells, and frequent development of hematologic autoimmunity. Dianzani autoimmune lymphoproliferative disease (DALD) has a similar phenotype but lacks the expansion of double-negative T cells. This work shows that patients with ALPS and DALD have high serum levels of interleukin 17A (IL-17A), IL-17F, and IL-17AF, which are involved in several autoimmune diseases, and that their T cells show increased secretion of these cytokines upon activation in vitro. The following data indicate that these cytokines may contribute to ALPS and DALD: (1) recombinant IL-17A and IL-17F significantly inhibit Fas-induced cell death in Fas-sensitive T cells from healthy donors; (2) this inhibitory effect is also induced by the patients' serum and is reversed by anti-IL-17A antibodies; (3) IL-17A neutralization substantially increases Fas-induced cell death in T cells from ALPS and DALD patients in vitro; and (4) treatment with anti-IL-17A antibodies ameliorates the autoimmune manifestations and, at a lesser extent, the lymphoproliferative phenotype and prolongs survival in MRLlpr/lpr mice, which are an animal model of ALPS. These data suggest that IL-17A and IL-17F could be targeted therapeutically to improve Fas function in ALPS and DALD.

    Autoimmune lymphoproliferative syndrome (ALPS) is an inherited disorder associated with defects in apoptosis, characterized by childhood onset of lymphadenopathy, splenomegaly, hyperimmunoglobulinemia, and autoimmune disease. ALPS is most frequently associated with a mutation in the cell death receptor Fas (CD95). Very rarely a mutation in caspase 10 is present. An increase of CD4/CD8 double negative T cells in the peripheral blood and lymph nodes is a feature characteristic of ALPS. Additionally, histiocytic proliferations resembling sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) were reported recently in patients with ALPS. In the rare cases with a caspase 10 mutation an accumulation of dendritic cells in lymphoid organs was noted. We describe a different, sarcoidosislike, histiocytic infiltration of lymph nodes that persisted for years in a girl, that was initially supposed to suffer from sarcoidosis, but was eventually diagnosed as ALPS, associated with a missense mutation in the intracellular death domain of Fas. This sarcoidosislike histologic picture extends the spectrum of histiocytic lymph node alterations observed in ALPS and alerts of a potential diagnostic pitfall.

    Results from a previous project "FarmClim" highlight that the IPCC default emission factor is not able to reflect region specific N2O emissions from Austrian arable soils. The methodology is limited in identifying hot spots and hot moments of N2O emissions. When estimations are based on default emission factors no recommendations can be given on optimisation measures that would lead to a reduction of soil N2O emissions. The better the knowledge is about Nitrogen and Carbon budgets in Austrian agricultural managed soils the better the situation can be reflected in the Austrian GHG emission inventory calculations. Therefore national and regionally modelled emission factors should improve the evidence for national deviation from the IPCC default emission factors and reduce the uncertainties. The overall aim of NitroAustria is to identify the drivers for N2O emissions on a regional basis taking different soil types, climate, and agricultural management into account. We use the LandscapeDNDC model to update the N2O emission factors for N fertilizer and animal manure applied to soils. Key regions in Austria were selected and region specific N2O emissions calculated. The model runs at sub-daily time steps and uses data such as maximum and minimum air temperature, precipitation, radiation, and wind speed as meteorological drivers. Further input data are used to reflect agricultural management practices, e.g., planting/harvesting, tillage, fertilizer application, irrigation and information on soil and vegetation properties for site characterization and model initialization. While at site scale, arable management data (crop cultivation, rotations, timings etc.) is obtained by experimental data from field trials or observations, at regional scale such data need to be generated using region specific proxy data such as land use and management statistics, crop cultivations and yields, crop rotations, fertilizer sales, manure resulting from livestock units etc. The farming

    The primary geologic processes shaping the landscape are physical and chemical weathering and the transport of solids by erosion. As part of our studies on the coupling between physical erosion and chemical weathering, we have determined depositional and erosional processes in New Zealand's tectonically active, rapidly uplifting Southern Alps, specifically focusing on the Hokitika River watershed. The South Island watersheds we are studying are subject to extreme orographic precipitation (as high as 7-12 m annually) and high landslide frequency, but have modest topography due to the rapid erosion. In concert with our studies of chemical weathering and physical erosion, we have used the atmospherically-delivered radionuclides of 7Be, 137Cs and 210Pbexcess to determine the relative magnitude of particle residence time in the high elevation Cropp and Whitcombe subwatersheds and the rates of sedimentation. One- and two-box modeling with 7Be and 210Pbexcess was used to determine soil and sediment residence times. Residence time of fine suspended particles is short and particles can travel the length of the river during a single storm, probably due to the short duration, high-intensity rainfalls which produce rapidly moving, steep flood waves. The readily detected peak of 137Cs activity in Cropp terrace and Hokitika gorge soils yielded sedimentation rates of 0.06-0.12 cm yr-1. At the Cropp terrace, inventory models of 210Pbexcess yield soil accumulation rates significantly less than those determined using the 137Cs activity peak. We attribute the differences to overestimation of 210Pbexcess in surface soils and to contrasting fallout fluxes, geochemical behavior and radionuclide contents of sedimenting materials. Total inventories of 210Pbexcess in soils greatly exceed the expected direct atmospheric deposition, suggesting that lateral transport of this nuclide occurs within the watershed. At the Hokitika gorge, all nuclides studied yielded similar sedimentation rates

    Risk assessment of snow avalanches is mostly related to weather conditions and snow cover. However a robust risk validation requires to identify all avalanches occurring, in order to compare predictions to real effects. For this purpose on December 2010 we installed a permanent 4-element, small aperture (100 m), infrasound array in the Alps, after a pilot experiment carried out in Gressonay during the 2009-2010 winter season. The array has been deployed in the Ayas Valley, at an elevation of 2000 m a.s.l., where natural avalanches are expected and controlled events are regularly performed. The array consists into 4 Optimic 2180 infrasonic microphones, with a sensitivity of 10-3 Pa in the 0.5-50 Hz frequency band and a 4 channel Guralp CMG-DM24 A/D converter, sampling at 100 Hz. Timing is achieved with a GPS receiver. Data are transmitted to the Department of Earth Sciences of the University of Firenze, where data is recorded and processed in real-time. A multi-channel semblance is carried out on the continuous data set as a function of slowness, back-azimuth and frequency of recorded infrasound in order to detect all avalanches occurring from the back-ground signal, strongly affected by microbarom and mountain induced gravity waves. This permanent installation in Italy will allow to verify the efficiency of the system in short-to-medium range (2-8 km) avalanche detection, and might represent an important validation to model avalanches activity during this winter season. Moreover, the real-time processing of infrasonic array data, might strongly contribute to avalanche risk assessments providing an up-to-description of ongoing events.

The contact between serpentinized peridotites and Fe-metagabbro/trondhjemite is locally lined by chloriteschist and rodingite. The high pressure parageneses in the Fe-metagabbro are omphacite-garnet-rutile-glaucophane-phengite, and in the metatrondhjemite plagioclase-quartz-phengite-clinozoisite-epidote-garnet, respectively. Bulk-rock major and trace elements in addition to O isotope analyses were performed in both rock types. Fe-metagabbros are characterized by MgO wt% ranging between 6.11 and 9.63%, ∑REE= 20-101 ppm, (La/Yb)N = 0.22-0.91; trondhjemites have SiO2 43%, Al2O3 ranging between 21 and 24%, CaO ranging between 17 and 20%, ∑REE = 172 - 272 ppm, (La/Yb)N ranging between 7.78 and 13.70. The δ18O is 5.9 ‰ in a Fe-metagabbro sample and 7.4 ‰ in a trondhjemite sample, suggesting that these rocks have been affected by a weak oceanic low temperature alteration. The high CaO content may indicate a metasomatic process which could have occurred during the oceanic stage or at high pressure conditions.

    Starting from results of Global Circulation Models, IPCC-based scenarios for the XXI century were selected and the expected time series for surface temperature and precipitation were extracted together with model results for the second half of the XX century for two regions of the southern Alps, in Italy. Both monthly and daily data were analysed. Monthly data were used to describe the variability of climatic data in terms of trend, and characteristic frequencies were singled out. Comparisons were made among results of different models and, for past data, experimental records collected in meteorological stations located in Northern Italy. The aim was to derive the expected trends in two watersheds where hydropower is well developed. From daily data, statistics on rainy events were derived and they were compared to experimental data, for model's verification. These results were used in a hydrological model in order to assess the expected changes of runoff regimes in the two watersheds. The model, of the semi-distributed and conceptual type, assumes the projected meteorological data as forcing for the XXI century. It also assumes that land use changes (snow and forest cover) will adapt to climate changes. In the area, in fact, an increase of the timberline altitude is already being observed, since the end of the Little Ice Age. Using detailed knowledge of characteristics of the hydropower plants and their past operation rules, and of irrigation uses downstream, the influence of climate change on hydropower production and water resources availability for irrigation and human use was extrapolated for the 21st century in these two representative basins.

    Full Text Available The Pays des Ecrins, which hosted the 2008 Alpine Week, is an emblematic mountain region of the French Alps that has to adapt in the face of numerous endogenous and exogenous crises and changes. Questions relating to creativity and innovation are thus raised in a structural manner and can be seen both as an injunction and a means to developing resources. Based on a review of the path taken by this region over the past twenty years, this paper examines the geo-historical and geo-cultural underpinnings of innovation in a context of local heritage and tourism development.Lieu d’accueil de la semaine alpine 2008, le Pays des Ecrins constitue un cas emblématique de territoire de montagne confronté à un impératif de mouvement face à de multiples facteurs de crise et de recomposition endogènes et exogènes.

A partir d’une relecture de la trajectoire de ce territoire à l’échelle des vingt dernières années, ce texte examine les conditions et les dynamiques géohistoriques et géoculturelles dans lesquelles la problématique de l’innovation peut être replacée dans un contexte de développement local patrimonial et touristique.

    Full Text Available Permafrost distribution modeling in densely populated mountain regions is an important task to support the construction of infrastructure and for the assessment of climate change effects on permafrost and related natural systems. In order to analyze permafrost distribution and evolution on an Alpine-wide scale, one consistent model for the entire domain is needed.

    We present a statistical permafrost model for the entire Alps based on rock glacier inventories and rock surface temperatures. Starting from an integrated model framework, two different sub-models were developed, one for debris covered areas (debris model and one for steep rock faces (rock model. For the debris model a generalized linear mixed-effect model (GLMM was used to predict the probability of a rock glacier being intact as opposed to relict. The model is based on the explanatory variables mean annual air temperature (MAAT, potential incoming solar radiation (PISR and the mean annual sum of precipitation (PRECIP, and achieves an excellent discrimination (area under the receiver-operating characteristic, AUROC = 0.91. Surprisingly, the probability of a rock glacier being intact is positively associated with increasing PRECIP for given MAAT and PISR conditions. The rock model was calibrated with mean annual rock surface temperatures (MARST and is based on MAAT and PISR. The linear regression achieves a root mean square error (RMSE of 1.6 °C. The final model combines the two sub-models and accounts for the different scales used for model calibration. Further steps to transfer this model into a map-based product are outlined.

    Full Text Available Abstract Background IT adoption is a process that is influenced by different external and internal factors. This study aimed 1. to identify similarities and differences in the prevalence of medical and nursing IT systems in Austrian and German hospitals, and 2. to match these findings with characteristics of the two countries, in particular their healthcare system, and with features of the hospitals. Methods In 2007, all acute care hospitals in both countries received questionnaires with identical questions. 12.4% in Germany and 34.6% in Austria responded. Results The surveys revealed a consistent higher usage of nearly all clinical IT systems, especially nursing systems, but also PACS and electronic archiving systems, in Austrian than in German hospitals. These findings correspond with a significantly wider use of standardised nursing terminologies and a higher number of PC workstations on the wards (average 2.1 PCs in Germany, 3.2 PCs in Austria. Despite these differences, Austrian and German hospitals both reported a similar IT budget of 2.6% in Austria and 2.0% in Germany (median. Conclusions Despite the many similarities of the Austrian and German healthcare system there are distinct differences which may have led to a wider use of IT systems in Austrian hospitals. In nursing, the specific legal requirement to document nursing diagnoses in Austria may have stimulated the use of standardised terminologies for nursing diagnoses and the implementation of electronic nursing documentation systems. Other factors which correspond with the wider use of clinical IT systems in Austria are: good infrastructure of medical-technical devices, rigorous organisational changes which had led to leaner processes and to a lower length of stay, and finally a more IT friendly climate. As country size is the most pronounced difference between Germany and Austria it could be that smaller countries, such as Austria, are more ready to translate innovation into

    The intestinal microbiota has a pivotal role in the maintenance of health of the human organism, especially in the defense against pathogenic microorganisms. Alterations in the microbiota, also termed dysbiosis, seem to be involved in the pathogenesis of a variety of intestinal and extraintestinal diseases. Fecal microbiota transplantation (FMT), also known as stool transplantation, is a therapeutic procedure aiming at restoring an altered intestinal microbiota by administration of stool microorganisms from a healthy donor into the intestinal tract of a patient. FMT is most commonly used for recurrent forms of Clostridium difficile infections (CDI). There are currently many cohort studies in a large number of patients and a randomized controlled trial showing a dramatic effect of FMT for this indication. Therefore FMT is recommended by international medical societies for the treatment of recurrent CDI with high scientific evidence. Other potential indications are the treatment of fulminant CDI or the treatment of inflammatory bowel diseases. In the practical utilization of FMT there are currently several open questions regarding the screening of stool donors, the processing of stool and the mode of FMT application. Different modes of FMT application have been described, the application into the colon has to be preferred due to less reported side effects than the application into the upper gastrointestinal tract. So far only very few side effects due to FMT have been reported, nevertheless the use and risks of FMT are currently intensely debated in the medical community. This consensus report of the Austrian society of gastroenterology and hepatology (ÖGGH) in cooperation with the Austrian society of infectious diseases and tropical medicine provides instructions for physicians who want to use FMT which are based on the current medical literature.

    The occurrence of genetic variants of Anaplasma phagocytophilum was studied in wild ungulates from the northern and central eastern Alps in Tyrol, Austria. For this purpose, spleen samples collected from 53 game animals during the hunting season 2008/2009 (16 roe deer [Capreolus capreolus], 10 red deer [Cervus elaphus], 16 Alpine chamois [Rupicapra r. rupicapra], 7 Alpine ibex [Capra i. ibex], and 4 European mouflons [Ovis orientalis musimon]) were analyzed. Thirty-five animals originated from the Karwendel mountains, 12 from the Kaunertal area (Ötztal Alps), and the remaining from other mountainous areas in Tyrol. DNA extracts were screened with a real-time polymerase chain reaction targeting the msp2 gene of A. phagocytophilum. A total of 23 (43.4%) samples, from all ungulate species studied, were A. phagocytophilum positive. As of the date of this article, A. phagocytophilum has not been reported in the Alpine ibex. The positive samples were investigated further with polymerase chain reactions for amplification of the partial 16S rRNA, groEL, and msp4 genes. Sequence analysis using forward and reverse primers revealed seven different 16S rRNA gene variants. No variant could be attributed to any particular ungulate species. The groEL gene revealed 11 different variants, which grouped in the phylogenetic analysis into two distinct clusters: one cluster contained the sequences from roe deer, whereas the sequences of the other species formed the second cluster. The msp4 gene showed a high degree of variability in the amplified part with a total of 10 different sequence types. The results show that the wild mountain ungulates were infected to a considerable extent with various variants of A. phagocytophilum. The pathogenicity of the variants and the reservoir competence of the species investigated in this study deserve further attention in future studies.

    2011-12-14

    An analytical method for the simultaneous determination of residues of eight neonicotinoid insecticides and two metabolites in honey using LC-MS/MS was developed and validated. Two approaches of sample preparation were investigated, with the final method involving acetonitrile extraction and subsequent cleanup by dispersive solid-phase extraction (QuEChERS type). Validation was based on quintuplicate analysis at three fortification levels and showed satisfactory recoveries (60-114%) and high precision (RSDs between 2.7 and 12.8%). Low limits of detection and quantification could be achieved for all analytes ranging from 0.6 to 5 μg/kg and from 2 to 10 μg/kg, respectively. Investigations of Austrian honey samples revealed the presence of acetamiprid, thiacloprid, and thiamethoxam residues in honey; however, no sample exceeded the maximum residue limits. On average, flower honey samples contained neonicotinoid residues in higher quantities compared to forest honey samples.

    Criteria, scoring systems, and treatment algorithms for myelodysplastic syndromes (MDS) have been updated repeatedly in recent years. This apparently results from increased awareness and early recognition of the disease, an increasing number of new diagnostic and prognostic markers and tools, and new therapeutic options that may change the course and thus prognosis in MDS. To address these challenges and to create useful new diagnostic and prognostic parameters and scores, the German-Austrian Working Group for Studying Prognostic Factors in MDS was established in 2003 and later was extended to centers in Switzerland (D-A-CH group). In addition, the group cooperates with the European LeukemiaNet, the MDS Foundation, and other national and international working groups in order to improve diagnosis and prognostication. The current article represents a meeting report from the latest workshop organized by the group in Vienna in October 2008.

    The Northern Calcareous Alps are characterized by complex lithological and tectonic settings, which are a consequence of the multiphase Alpine orogeny. Several tectonic events caused a varying structural anisotropy with a high susceptibility towards certain types of gravitational mass movement. Mt. Plassen is situated west of the Hallstatt village (Upper Austria). It is composed of Jurassic limestone, which overlies Permotriassic fine-grained clastic rocks and evaporites (mainly part of the so-called Haselgebirge). This geotechnical predisposition causes rock spreading of the more hard and rigid limestone on the weak, mainly clayey rocks. Associated to this large slope instability are secondary rockfall and sliding processes. Further common process chains include rockfall triggering slides and/or earth flows by undrained loading of the ductile clay material. Thus, such fast moving flows/slides may endanger the houses and infrastructures in the Salzberg high valley and Hallstatt village. Recent rockfall activity at Mt. Plassen provide evidences for greater, perhaps accelerating displacement rates of the rock spread. A multidisciplinary assessment strategy was chosen to analyse the ground conditions, to characterize the potential failure mechanisms in more detail and to evaluate the hazard potential of future events. Methods include field mapping (geologic, engineering geologic and geomorphologic), sampling and determination of soil parameters in active process areas, geophysical surveys (airborne geophysics and geoelectric measurements) and kinematic measurements (tape dilatometer and geodetic measurements over a period of 50 years). Results of this multidisciplinary approach form the basis for further decision making such as the installation of a monitoring system or other preventive measures.

    Highlights: {yields} The cytoskeleton-associated protein, smALP, is expressed in differentiated skeletal muscle. {yields} smALP is translocated from the cytoplasm to the nucleus of C2C12 myoblasts upon induction of myogenesis. {yields} The differentiation-dependent nuclear translocation of smALP occurs in parallel with the nuclear accumulation of myogenin. {yields} The LIM domain of smALP is essential for the nuclear accumulation of the protein. {yields} smALP might act in the nucleus to control some critical aspect of the muscle differentiation process. -- Abstract: The skALP isoform has been shown to play a critical role in actin organization and anchorage within the Z-discs of skeletal muscles, but no data is available on the function of the smALP isoform in skeletal muscle cells. Here, we show that upon induction of differentiation a nuclear translocation of smALP from the cytoplasm to the nucleus of C2C12 myoblasts, concomitant to an up-regulation of the protein expression, occurs in parallel with the nuclear accumulation of myogenin. Moreover, we demonstrate that the LIM domain of smALP is essential for the nuclear translocation of the protein.

    AIM: To construct a recombinant strain which expresses adhesin AlpA of Helicobacter pylori(H pylori) and to study the immunogenicity of adhesin AlpA.METHODS: Gene Ab, which was amplified from H pylori chromosomal DNA by PCR technique, was sequenced and the biological information was analyzed, and inserted into the Nco Ⅰ and NotⅠ restriction fragments of the expression vector pET-22b(+) using T4 DNA ligase. The resulting plasmid pET-AlpA was transformed into competent E.coli BL21(DE3) cells using ampicillin resistance for selection.Recombinant strains were incubated in 5 mL LB with 100 μg/mL ampicillin overnight at 37 ℃. Sonication of BL21(DE3)pET-22b(+)/AlpA was analyzed by Western blot to detect AlpA immunogenicity.RESULTS: The gene encoding AlpA protein was amplified by PCR with chromosomal DNA of H pylori Sydney strain (SS1) as templates. It revealed that AlpA DNA fragment amplified by PCR had approximately 1 500 nucleotides,compatible with the previous reports. The recombinant plasmid pET-22b(+)/AB was successfully constructed. DNA sequencing showed one open reading frame with the length of 588 bp. It encoded seven conservative regions that showed good antigenicity and hydrophobicity by Parker and Welling method. Furthermore, INTERNET EXPASY,NNPREDICT and ISREC predicted that it was a porin-like structure consisting of β-pleated sheets that were embedded in the outer membrane. BLAST analyzed 836 767 protein sequences and found that the similar sequences were all belonging to H pylori OMP sequences. SDS-PAGE and scan analysis showed that the molecular weight of AB was 22.5 ku and recombinant protein amounted to 29% of the total bacterial protein, among which dissolved expression amounted to 21.9% of sonicated supernatant. The rAB purity amounted to 96% through affinity chromatography.Western blot analysis of rAB confirmed that it could be specially recognized by serum form rabbit immunized with AlpA and H pylori infected.CONCLUSION: Adhesin Alp

  5. Assessing Glacier Hazards At Ghiacciaio Del Belvedere, Macugnaga, Italian Alps

    Haeberli, W.; Chiarle, M.; Mortara, G.; Mazza, A.

    The uppermost section of the Valle Anzasca behind and above the community of Macugnaga in the Italian Alps is one of the most spectacular high-mountain land- scapes in Europe, with gigantic rock walls and numerous steep hanging glaciers. Its main glacier, Ghiacciaio del Belvedere at the foot of the huge Monte Rosa east face, is a heavily debris-covered glacier flowing on a thick sediment bed. Problems with floods, avalanches and debris flows from this ice body have been known for extended time periods. Most recently, however, the evolution of this highly dynamic environ- ment has become more dramatic. An outburst of Lago delle Locce, an ice-dammed lake at the confluenec of the tributary Ghiacciaio delle Locce with Ghiacciaio del Belvedere, caused heavy damage in 1979 and necessitated site investigation and con- struction work to be done for flood protection. The intermittent glacier growth ten- dency in the 1970es induced strong bulging of the glacier surface and, in places, caused the glacier tongue to override historical morains and to destroy newly-grown forest stands. A surge-type flow acceleration started in the lower parts of the Monte- Rosa east face during summer 2000, leading to strong crevassing and deformation of Ghiacciaio del Belvedere and extreme bulging of its orographic right margin. High water pressure and accelerated movement lasted into winter 2001/2002: the ice now started overriding the LIA moraine near Rifugio Zamboni of the CAI. In addition but rather independently, a most active detachment zone for rock falls and debris flows developed for several years now in the east face of Monte Rosa, somewhat more to the south of the accelerated glacier movement and at an altitude where relatively warm permafrost must be expected. Besides the scientific interest in these phenomena, the growing hazard potential to the local infrastructure must be considered seriously.

    Natural gas emanations are part of the geochemical baseline to take into account when assessing global greenhouse gas emissions and potential impacts of conventional and unconventional gas exploration and exploitation on groundwater. Examples of such natural gas macro-seeps are known in several parts of the world (Etiope et al., 2009). Only a limited number of them have been characterized for their gas and isotopic compositions. Such analyses can provide essential information for baseline studies, providing insight in the sources (biogenic vs. thermogenic or modified thermogenic) and pathways of such seeps and may allow for distinction of natural seeps from stray gas leakage associated with human activities. Here, we report gas concentrations and multi-isotope data (δ13C and δ2H of methane and ethane, δ13C and δ18O of CO2, 3He/4He ratio) of two gas seeps in the French subalpine chains, both in a similar geological and structural position within Middle Jurassic claystones along the eastern border of the large synclinal structures of the Vercors and the Chartreuse massifs (Moss, 1992). The "ardent fountain" (fontaine ardente) of Le Gua, 30 km south of Grenoble has most likely the longest continuous written record of existence of any individual natural gas seep, mentioned explicitly as early as the first quarter of the 5th century (Augustin of Hippo (St. Augustin), approx. 426) This natural seep was described in the past as a "wet seep" associated with a spring, whereas the second investigated seep, Rochasson near Meylan north of Grenoble, is a dry seep. Both seeps contain methane and ethane with thermogenic C and H isotope signatures, comparable with a seep in the Northern Swiss Alps at Giswil (Etiope et al., 2010) but with a higher dryness (C1/(C2+C3)>1000) for the Le Gua seep, possibly due to molecular fractionation upon advective fluid+gas migration (Etiope et al., 2009). Maturity (R0) of the reservoir rocks deduced from δ13C(CH4), δ13C(C2H6) is similar to

    Autoimmune lymphoproliferative syndrome (ALPS) caused by impaired FAS-mediated apoptosis of lymphocytes is characterized by lymphoproliferation, autoimmunity, but also an increased risk of invasive bacterial infection, notably following splenectomy. We surveyed a cohort of 100 ALPS patients (including 33 splenectomized) and found that 12 (10 splenectomized) had experienced 23 invasive bacterial infections mainly caused by Streptococcus pneumoniae. This vulnerability was associated with evidence of defective B-cell function characterized by low serum immunoglobulin (Ig) M, low IgM antibody production in response to S pneumoniae following nonconjugated immunization, and low blood memory B-cells counts (including marginal zone [MZ] B-cell counts). This immunodeficiency strongly correlated with intensity of lymphoproliferation. Spleen sections from 9 ALPS patients revealed double-negative T-cell (DN-T) infiltration of the MZ, which was depleted of B cells. MZ in ALPS patients contained an abnormally thick layer of MAdCAM-1((+)) stromal cells and an excess of DN-Ts. DN-Ts were shown to express MAdCAM-1 ligand, the α4β7 integrin. These observations suggest that accumulating DN-Ts are trapped within stromal cell meshwork and interfere with correct localization of MZ B cells. Similar observations were made in spleens of fas-deficient mice. Our data revealed an unexpected mechanism by which ALPS results in anti-polysaccharide IgM antibody production-specific defect. Splenectomy should be avoided.

    Full Text Available This introductory paper presents and summarises recent research on meteorological and hydrological aspects of floods in the Alps. The research activities were part of the international research project RAPHAEL (Runoff and Atmospheric Processes for flood HAzard forEcasting and controL together with experiments within the Special Observing Period-SOP conducted in autumn 1999 for the Mesoscale Alpine Programme —MAP. The investigations were based on both field experiments and numerical simulations, using meteorological and hydrological models, of ten major floods that occurred in the past decade in the European Alps. The two basins investigated were the Ticino (6599 km2 at the Lago Maggiore outlet on the southern side of the Alps and the Ammer catchment (709 km2 in the Bavarian Alps. These catchments and their sub-catchments cover an appropriate range of spatial scales with which to investigate and test in an operational context the potential of both mesoscale meteorological and distributed hydrological models for flood forecasting. From the data analyses and model simulations described in this Special Issue, the major sources of uncertainties for flood forecasts in mid-size mountain basins are outlined and the accuracy flood forecasts is assessed.

    Axion like particles (ALPs) are quite generic in many scenarios for physics beyond the Standard Model, they are pseudoscalar Nambu-Goldstone bosons, and appear once any global $U(1)$ symmetry is broken spontaneously. The ALPs can gain mass from various non-perturbative quantum effects, such as anomalies or instantons. ALPs can couple to the matter sector incluidng a scalar condensate such as inflaton or moduli field via derivative interactions, which are suppressed by the axion {\\it decay constant}, $f_\\chi$ . Although weakly interacting, the ALPs can be produced abundantly from the coherent oscillations of a homogeneous condensate. In this paper we will study such a scenario where the ALPs can be produced abundantly, and in some cases can even overclose the Universe via odd and even dimensional operators, as long as $f_\\chi/\\Phi_{\\rm I} \\ll 1$, where $\\Phi_{\\rm I}$ denotes the initial amplitude of the coherent oscillations of the scalar condensate, $\\phi$. We will briefly mention how such dangerous overprodu...

    The adjacent lone pair (ALP) effect is an experimental phenomenon in certain nitrogenous heterocyclic systems exhibiting the preference of the products with lone pairs separated over other isomers with lone pairs adjacent. A theoretical elucidation of the ALP effect requires the decomposition of intramolecular energy terms and the isolation of lone pair-lone pair interactions. Here we used the block-localized wavefunction (BLW) method within the ab initio valence bond (VB) theory to derive the strictly localized orbitals which are used to accommodate one-atom centered lone pairs and two-atom centered σ or π bonds. As such, interactions among electron pairs can be directly derived. Two-electron integrals between adjacent lone pairs do not support the view that the lone pair-lone pair repulsion is responsible for the ALP effect. Instead, the disabling of π conjugation greatly diminishes the ALP effect, indicating that the reduction of π conjugation in deprotonated forms with two σ lone pairs adjacent is one of the major causes for the ALP effect. Further electrostatic potential analysis and intramolecular energy decomposition confirm that the other key factor is the favorable electrostatic attraction within the isomers with lone pairs separated.

  11. The Central Role of Neuroscientists under National Socialism.

    Neuroscientists played central roles in the victimization of colleagues and their patients during the era of National Socialism from 1933 to 1945. After helping dismiss Jewish and nonideologically aligned colleagues, German neuroscientists were among the physicians and researchers who joined the Nazi Party and affiliated groups in record numbers. Forced sterilization and then so-called 'euthanasia' of neurological and psychiatric patients were planned and executed by prominent German and Austrian neuroscientists. Other neuroscientists collaborated indirectly by using patients for unethical experimentation to discover the cause of multiple sclerosis or to try to induce epileptic convulsions in a hypoxic state. Some merely used neuropathological material from murdered patients for publications in scientific journals. In the totalitarian state, research funding and academic advancement were awarded to physicians engaged in eugenics research. Opportunism and ideologically tainted science without regard to medical ethics were the motivating factors for collaborating neuroscientists. Some German and Austrian neuroscientists tried to resist Nazi policies, although much more passively than their colleagues in German-occupied countries. French, Dutch, Norwegian, and Danish neuroscientists actively resisted the Nazification of their profession from the beginning and helped to save some patients and colleagues, at great personal risk. Many German, Austrian, Czech, and Polish neurologists were murdered in the Holocaust, and hundreds of thousands of neurological and psychiatric patients were sterilized or murdered in just 12 years. The Nazis used the 'successful' techniques developed in the 'euthanasia' programs to carry out the mass murder of millions in the Holocaust. Today's neuroscientists are obligated to learn of the ethical violations of their predecessors 70-80 years ago. No law will prevent abandonment of the basic principles of ethical patient care and professionalism

    The Trentino region is located at the junction between the central and eastern Southern Alps (Italy), at the intersection between the Giudicarie, Schio-Vicenza and Valsugana fault systems. This area is characterized by relevant lithological and structural lateral heterogeneities, both at the crustal and lithospheric scales. A low-to-moderate seismicity is located in the upper crust, where faults are seismically active under a dominant compressive with variable strike-slip component regime. Here we study the crustal structure of this portion of the Southern Alps (Adria plate) from interpretation of local earthquake tomography images, in relation with distribution of relocated seismicity and regional tectonic patterns. Local earthquake tomography derives from a set of 476 selected earthquakes in the period 1994-2007, with local magnitudes comprised between 0.8 and 5.3. Hypocenter distribution, and number and quality of manually-repicked phases (6322 P and 5483 S) ensure optimal seismic ray coverage. Original recordings are principally from the Provincia Autonoma di Trento (PAT), that manages the Trentino seismic network since 1981, and from other networks (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale - INOGS; Istituto Nazionale di Geofisica e Vulcanologia - INGV; others available via the European Integrated Data Archive). The code HYPOELLIPSE is used to perform initial earthquake relocations. The code VELEST is then used to calculate a new minimum 1-D velocity model, as input for tomography. The 3-D tomographic inversion (V P and V P-V S ratio) is obtained via the code SIMULPS, with the implementation of an accurate shooting ray-tracer. The crustal volume is discretized in order to have a regular grid with a homogenous horizontal spatial resolution of 7.5 km. The resolution in depth varies according to the obtained minimum 1-D velocity model. Reliability and accuracy of results are estimated by analyzing the Resolution Diagonal Elements of the

    fractured clasts up to boulder size. Comparison with areas with intense neotectonism (e. g., Central Apennines) suggests that fracturation may have been caused by seismicity. For the area, historical earthquakes with Me 3-3.9 imply the incidence of stronger quakes on longer timescales. The considered rock avalanche thus perhaps was triggered by a seismic event. The investigated RAD is the hitherto unappreciated, easternmost outlier of a cluster of rock avalanches in the area; these rock avalanches are grouped within a seismically active belt of strike-slip faults related to the Neogene to recent deformation of the Eastern Alps. This study links structural deformation with catastrophic mass-wasting which, in turn, caused incision of an epigenetic bedrock gorge. Surface exposure dating of boulders is intended to constrain the age of rock avalanching.

    The NE trending Belledonne faults system, located in the Alps, is a potentially active faults system that extends from the Aiguilles Rouges and Mont Blanc massifs in the NE to the Vercors massif in the SW (subalpine massifs). It includes the Belledonne border fault (BBF), defined by an alignment of micro earthquakes (ML≤3.5) along the eastern part of the Grésivaudan valley (Thouvenot et al., 2003). Focal mechanisms and their respective depths tend to confirm a dextral strike-slip faulting at crustal scale. In the scope of the Sigma project (http://projet-sigma.com/index.html, EDF), this study aims at better constraining the geometry, kinematic and seismogenic potential of the constitutive faults of the Belledonne fault system, by using a multidisciplinary approach that includes tectonics, geomorphology and geophysics. Fault kinematic analysis along the BBF (Billant et al., 2015) and the Jasneuf fault allows the determination of a strike-slip tectonic regime characterised by an ENE trending σ1 stress axes, which is consistent with stress state deduced from the focal mechanisms. Although no morphological anomalies could be related to recent faulting along the BBF, new clues of potential Quaternary deformations were observed along the other faults of the system: -right lateral offset of morphologic markers (talwegs...) along the NE trending Arcalod fault located at the north-eastern terminations of the BBF; -left lateral offset of the valley formed by the Isère glacier along the NW trending Brion fault which is consistent with its left-lateral slip inferred from the focal mechanisms; -fault scarps and right lateral offsets of cliffs bordering a calcareous plateau and talwegs along the four fault segments of the NE trending Jasneuf fault located at the south-western termination of the BBF in the Vercors massif. Some offsets were measured using a new method that does not require the identification of piercing points and take advantage of the high resolution

    The nationwide Austrian Breast Cancer Early Detection Programme (''BKFP'') started in January 2014. The Austrian Agency for Health and Food Safety Ltd. was entrusted with running the reference center for technical quality control (''RefZQS'') on April 1, 2014. The quality of the radiologists' equipment is evaluated against the standards described in the EUREF-Oeprotocol, which is based on the European guidelines for quality assurance in breast cancer screening and diagnosis (EPQC V4, 2006) and has been optimized for Austrian requirements. In its first year of operation the RefZQS has controlled the entire equipment (mammography, periphery and ultrasound system) of all participating radiologists. A significant number of systems had to be adjusted to meet the EUREF-Oecriteria. Some of the systems could not be adjusted accordingly, and had to be replaced. In the wake of the start of the screening programme, several sites switched from CR to more modern DR systems, yielding a significant benefit by reduction of radiation burden. The most important data after one year of RefZQS, especially according to adjustments and replacements, are presented.

    Full Text Available Abstract Background Disease management programmes (DMPs are costly and impose additional work load on general practitioners (GPs. Data on their effectiveness are inconclusive. We therefore conducted a cluster-randomised controlled trial to evaluate the effectiveness of the Austrian DMP for diabetes mellitus type 2 on HbA1c and quality of care for adult patients in primary care. Methods All GPs of Salzburg-province were invited to participate. After cluster-randomisation by district, all patients with diabetes type 2 were recruited consecutively from 7-11/2007. The DMP, consisting mainly of physician and patient education, standardised documentation and agreement on therapeutic goals, was implemented in the intervention group while the control group received usual care. We aimed to show superiority of the intervention regarding metabolic control and process quality. The primary outcome measure was a change in HbA1c after one year. Secondary outcomes were days in the hospital, blood pressure, lipids, body mass index (BMI, enrolment in patient education and regular guideline-adherent examination. Blinding was not possible. Results 92 physicians recruited 1489 patients (649 intervention, 840 control. After 401 ± 47 days, 590 intervention-patients and 754 controls had complete data. In the intention to treat analysis (ITT of all 1489 patients, HbA1c decreased 0.41% in the intervention group and 0.28% in controls.

    Detrital zircons from Cretaceous micaschist, late Eocene-earliest Oligocene sandstone and early Oligocene siltstone of the Western Alps fall into three main separable age clusters at 610-540 Ma, 490-430 Ma, and 340-280 Ma that correspond to the Cadomian (Neoproterozoic), Ordovician, and Variscan (Carboniferous) events widespread in western and central Europe. Hf isotopic results indicate that these three magmatic and tectonic episodes did not give rise to significant production of juvenile crust. A distinguishable group of Triassic zircons, around 250-200 Ma which is considered to derive from the Southern Alps, has been detected in the early Oligocene "Schistes à Blocs" formation and the Briançonnais "Flysch Noir". In contrast, this age group is absent in late Eocene to earliest Oligocene sandstones. In agreement with sedimentological studies, our results show that the main source areas of the Eocene sandstone were probably located in the European continent. The arrival of detritus from the Internal Zone occurred in early Oligocene, coeval with the tectonic rotation from northwestward to westward in the propagation of allochthonous units. Based on previous studies and our new data, we argue that the Briançonnais Zone was likely a paleorelief since the middle Eocene that accounts for the lack of detritus from the Adriatic units. Contemporary sediments were accumulated in the foredeep of the Adriatic plate. From Oligocene time onward, the blockage was cut through after a regional uplifting, and thus, the Internal Zone started to provide detritus into the western flexural basins.

  9. Biodiversity governance and social-ecological system dynamics: transformation in the Australian Alps

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Biodiversity conservation continues to be a challenging task for societies worldwide. We undertook a resilience assessment to address the following question: What are the ramifications of social-ecological system dynamics for biodiversity governance of a nationally significant landscape? Resilience assessment offers promise for guiding response strategies, potentially enabling consideration of ecological, social, economic, and governance influences on biodiversity-related activities. Most resilience assessments have, however, struggled to effectively incorporate governance influences. We applied a modified version of the Resilience Alliance workbook approach to explicitly address governance influences at each stage of an assessment of internationally significant biodiversity features in protected areas of the Australian Alps. The vulnerability of the Alps system to climate change suggests that it is moving into a release stage, with subsequent transformation hypothesized. Network governance is argued as enabling flexible, adaptive management and comprehensive engagement of stakeholders, both of which are critical to shaping how this transformation of the Alps as a valued focal system will occur. The Australian Alps Liaison Committee provides a promising governance structure for collaboration and comanagement across multiple jurisdictions. Our contribution was to demonstrate how a resilience assessment that explicitly embeds governance influences in social-ecological system dynamics can point to pathways for governance reform in the context of system transformation.

  10. Money Supply as the Target of the Central Bank

    Directory of Open Access Journals (Sweden)

    Jędruchniewicz Andrzej

    2014-06-01

    Full Text Available The main purpose of the article is a critical analysis of the monetary policy strategy that is based on the adoption of money supply as an intermediate target. The analysis is conducted from the perspective of the theory of the Austrian school. The first part of the article presents an influence of the supply of money on changes of categories in economy according to mainstream theories of economics. The second part discusses the essence of the strategy of monetary policy using money supply as an intermediate target from the point of view of the main trend in economics. It is demonstrated that in order to use it, two elementary conditions must be met: the function of demand for money must be at least relatively stable and the central bank must practically shape changes in the money supply at the planned level. The third part is of key importance for the purpose of this article. It involves the criticism of Friedman’s principle, i.e. a constant increase in money supply as a monetary strategy. According to the Austrian theory, an increase in the quantity of money which is not financed by voluntary savings separates the time structure of production and consumption. Thus, after the period of prosperity there a collapse in production must take place. It is also pointed out that the crisis can be postponed only when the quantity of money increases at an ever faster rate.

    2007-01-01

    Full Text Available A precondition necessary for creation and selection of genotypes tolerant of stress conditions is a study of physiological, biochemical and molecular bases of their adaptive reaction to stress. The study includes 40 lines of free pollination originating from 5 provenances: Sutjeska, Višegrad, Tara, Teslić and Durmitor (B&H, Serbia and Montenegro. Two populations were selected from each provenance, i.e.: 5 lines of free pollination represent the population growing on the cliffs and 3 lines of free pollination represent the population growing at the best site of Austrian pine. Specific characteristics of the studied provenances, populations, and free pollination lines were confirmed by the analyses in the salt-soluble proteins. The identical protein composition was proved in a small number of cases in the replicates of the same free pollination line, which indicates a high intra-line variability, which can be the result of the effect of father, as well as of heterozygosity of mother trees. The analyses of protein composition of seed showed considerable differences at provenance level. Inter-line, population and provenance differences, and also, the interaction between the origin and drought factor, were recorded for 9-day-old seedlings germinated in induced drought conditions and in normal conditions.

    2016-02-01

    We report on two cases of necrotizing fasciitis of the lower leg due to nontoxigenic Vibrio cholerae (V. cholerae). A 73-year-old woman (case 1) and an 80-year-old man (case 2) were hospitalized with symptoms of necrotizing fasciitis on July 18 and August 15, 2015, respectively. In both cases, symptoms started the day after swimming in local ponds. Swabs gained intraoperatively and a blood culture from the male patient, yielded V. cholerae non-O1/non-O139, negative for cholera toxin gene ctx and positive for hemolysin genes hlyA and hlyB. Water samples taken from pond A on August 17, 2015 (32 days after exposure of case 1) and from pond B on August 20, 2015 (7 days after exposure of case 2) yielded non-O1/non-O139 V. cholerae in most-probable numbers of > 11,000 per 100 ml each. The occurrence of two cases of necrotizing fasciitis within a 1 month period related to two Austrian non-saline bathing waters, previously not known to harbor V. cholerae, is probably linked to the prevailing extreme weather conditions (heat wave, drought) this summer in Austria. While case 1 was discharged in good clinical condition after 73 days, case 2 died after four months of hospitalization. Public health authorities are challenged to assess the effects of long-term climate change on pathogen growth and survival in continental bodies of fresh water.

    The new expert recommendation from the Austrian Society of Obstetrics and Gynaecology (OEGGG) comprises an interpretation and summary of guidelines from the leading specialist organisations worldwide (RCOG, ACOG, SOGC, CNGOF, WHO, NIH, NICE, UpToDate). In essence it outlines alternatives to the direct pathway to elective repeat caesarean section (ERCS). In so doing it aligns with international trends, according to which a differentiated, individualised clinical approach is recommended that considers benefits and risks to both mother and child, provides detailed counselling and takes the patient's wishes into account. In view of good success rates (60-85 %) for vaginal birth after caesarean section (VBAC) the consideration of predictive factors during antenatal birth planning has become increasingly important. This publication provides a compact management recommendation for the majority of standard clinical situations. However it cannot and does not claim to cover all possible scenarios. The consideration of all relevant factors in each individual case, and thus the ultimate decision on mode of delivery, remains the discretion and responsibility of the treating obstetrician.

    Full Text Available The paper builds on our previous work in the field of bilingual education and/ or the process of natural bilingualisation of Slovak-German bilinguals in Slovak educational diasporas (educational islands in Austria. Starting point of psycholinguistic testing based on classic American Peabody Picture Vocabulary Test ( PPVT -III in its revised and German version presented in this paper is the thesis of initial lagging behind of linguistic (lexical, grammatical competence level of language L2 of bilingual children from preschool age in relation to various sociolinguistic variables, which, however, with age may, under certain favourable conditions nearly equal competence of monolinguals and in the area of reception of language even exceed it. For testing the reception levels of German mental lexicon we used two approximately equally large groups of respondents in a bilingual secondary grammar school in Bratislava and Vienna. The hypothesis of our research was that bilingual Austrian-Czech/Slovak bilinguals from Austria would achieve significantly better results than the Slovak-German bilinguals from Slovakia. The test results, however, surprisingly disproved our hypothesis and want to contribute to the debate on setting minimum standards of language competence of bilinguals as well as on optimisation of conditions of bilingual or monolingual education of not only Slovaks abroad.

    This study is reporting an outbreak of subclinical mastitis due to beta-hemolytic group L streptococci in an Austrian dairy herd with a history of high somatic cell count. At the first survey 16 of 33 lactating cows (28 quarters of 132) were cultured positive for beta-hemolytic, CAMP and esculin negative cocci that grew on Columbia blood agar with small grey catalase negative colonies. With the commercial API 20 Strep system (bioMerieux, F) isolates were classified as members of streptococci group L. All tested strains (eight of 28) produced acid from ribose, lactose, trehalose, amidon and glycogen; they hydrolysed hippurate and showed beta-glucuronidase, beta-galactosidase, alkaline phosphatase, leucinaminopeptidase and arginindehydrolase activity. Isolates were sensitive to bacitracin but resistant to tetracycline. Using phenotypic characterisation as well as sequence analysis of the 16S-23S intergenic spacer region of a representative strain, recovered isolates were identified as Streptococcus (S.) dysgalactiae ssp. equisimilis. Mastitis was characterized by normal milk secretions and absence of clinical abnormalities but high elevations of somatic cell count. Based on the characteristics of the strains and on the observations during the first herd survey, contagious transmission during milking as a result of poor milking hygiene was assumed. The mastitis was controlled through implementation of a strict hygiene protocol including use of single-use udder towels, post milking teat desinfection and cluster disinfection between milking cows in combination with antibiotic treatment of infected udders.

  16. Characterization of Modern and Fossil Mineral Dust Transported to High Altitude in the Western Alps: Saharan Sources and Transport Patterns

    2012-01-01

    Full Text Available Mineral dust aerosols recently collected at the high-altitude Jungfraujoch research station (N, E; 3580 m a.s.l. were compared to mineral dust deposited at the Colle Gnifetti glacier (N, E; 4455 m a.s.l. over the last millennium. Radiogenic isotope signatures and backward trajectories analyses indicate that major dust sources are situated in the north-central to north-western part of the Saharan desert. Less radiogenic Sr isotopic compositions of PM10 aerosols and of mineral particles deposited during periods of low dust transfer likely result from the enhancement of the background chemically-weathered Saharan source. Saharan dust mobilization and transport were relatively reduced during the second part of the Little Ice Age (ca. 1690–1870 except within the greatest Saharan dust event deposited around 1770. After ca. 1870, sustained dust deposition suggests that increased mineral dust transport over the Alps during the last century could be due to stronger spring/summer North Atlantic southwesterlies and drier winters in North Africa. On the other hand, increasing carbonaceous particle emissions from fossil fuel combustion combined to a higher lead enrichment factor point to concomitant anthropogenic sources of particulate pollutants reaching high-altitude European glaciers during the last century.

    A centralizer assembly is disclosed that allows for the assembly to be deployed in-situ. The centralizer assembly includes flexible members that can be extended into the well bore in situ by the initiation of a gas generating device. The centralizer assembly can support a large load carrying capability compared to a traditional bow spring with little or no installation drag. Additionally, larger displacements can be produced to centralize an extremely deviated casing.

    High-altitude areas in the European Alps have been widely investigated through time for reconstructing the Holocene climate fluctuations, by analyzing both biological and abiological indicators. In high-altitude areas the ongoing temperature increase caused some effects in the natural environments such as the upward shift of the vegetation belts and, in particular, of the treeline. In fact, the treeline is considered a sensitive climate indicator; in high-altitude areas, the vegetation growth and dynamics are strongly influenced not only by climate but also by abiotic factors, like geomorphological processes and soil development. The aim of this study is the reconstruction of late Holocene soil evolution and environmental changes at the treeline on the SW slope of the Monte Confinale in the Upper Valtellina, Central Italian Alps. We performed a detailed reconstruction of the treeline altitudinal dynamics together with the field and laboratory characterization of a transect of nine soil profiles developing at an altitude ranging from 1800 m a.s.l. (closed forest) to 2600 m a.s.l. (species line), in order to understand the relationship between colonization by arboreal vegetation and soil development. The upward shift of the treeline was assessed analyzing tree age distribution on the slope by means of a tree-ring based approach. The treeline elevation over time (based on the years in which the trees reached 2 m in height) increased from 2505 m a.s.l. (period 1990-1999) to 2531 m (period 2000-2009) to 2545 m (in 2013) with a rate of upward shift of up to 2.6 m/y in the period 2000-2009. The investigated soils showed a decreasing development with increasing altitude, in fact at higher altitude we found less developed soils (i.e. Ranker), on the contrary in the forest area (about 2000 m a.s.l.) we found a more developed soil (i.e. Podzol). Moreover, the soil development may also be affected by the conditions of the slope, characterized by broad alpine grasslands that

    Flood hazard is expected to increase in the context of global warming. However, long time-series of climate and gauge data at high-elevation are too sparse to assess reliably the rate of recurrence of such events in mountain areas.

The aim was to document a possible effect of the post-19(th) century global warmi...

  20. End of the "Little Ice Age" in the Alps not forced by industrial black carbon

    Light absorbing aerosols present in the atmosphere and cryosphere play an important role in the climate system. Their presence in ambient air and snow changes radiative properties of these media, thus contributing to increased atmospheric warming and snowmelt. High spatio-temporal variability of aerosol concentrations in these media and a shortage of long-term observations contribute to large uncertainties in properly assigning the climate effects of these aerosols through time. Glaciers in the European Alps began to retreat abruptly from their mid-19th century maximum, marking what appeared to be the end of the Little Ice Age. Radiative forcing by increasing deposition of industrial black carbon to snow has been suggested as the main driver of the abrupt glacier retreats in the Alps (Painter et al. 2012). Basis for this hypothesis were model simulations using ice-core measurements of elemental carbon at low temporal resolution from two ice cores in the Alps. Here we present sub-annually resolved, well replicated ice-core measurements of refractory black carbon (rBC; using a SP2 soot photometer), mineral dust (Fe, Ca), biomass burning (NH4, K) and distinctive industrial pollution tracers (Bi, Pb, SO4) from an ice core in the Alps covering the past 250 years. These reconstructions allow to precisely compare the timing of observed acceleration of glacier melt in the mid-19th century with that of the increase of soot deposition on ice-sheets caused by the industrialization of Western Europe. Our study suggests that at the time when European rBC emission rates started to significantly increase Alpine glaciers have already experienced more than 70% of their total 19th century length reduction. Industrial BC emissions can therefore not been considered as the primary forcing of the rapid deglaciation at the end of the Little Ice Age in the Alps. References: Painter, T. H., M. G. Flanner, G.

    The MARS2013 mission: The Austrian Space Forum together with multiple scientific partners will conduct a Mars analog field simulation. The project takes place between 1st and 28th of February 2013 in the northern Sahara near Erfoud. During the simulation a field crew (consisting of suited analog astronauts and a support team) will conduct several experiments while being managed by the Mission Support Center (MSC) located in Innsbruck, Austria. The aim of the project is to advance preparation of the future human Mars missions by testing: 1) the mission design with regard to operational and engineering challenges (e.g., how to work efficiently with introduced time delay in communication between field team and MSC), 2) scientific instruments (e.g., rovers) and 3) human performance in conditions analogous to those that will be encountered on Mars. The Role of Geological Mapping: Remote Science Support team (RSS) is responsible for processing science data obtained in the field. The RSS is also in charge of preparing a set of maps to enable planning activities of the mission (including the development of traverses) [1, 2]. The usage of those maps will increase the time-cost efficiency of the entire mission. The RSS team members do not have any prior knowledge about the area where the simulation is taking place and the analysis is fully based on remote sensing satellite data (Landsat, GoogleEarth) and a digital elevation model (ASTER GDEM)from the orbital data. The maps design: The set of maps (covering area 5 km X 5 km centered on the Mission Base Camp) was designed to simplify the process of site selection for the daily traverse planning. Additionally, the maps will help to accommodate the need of the field crew for the increased autonomy in the decision making process, forced by the induced time delay between MSC and "Mars". The set of provided maps should allow the field team to orientate and navigate in the explored areas as well as make informed decisions about

    The entrepreneurial spirit theory in Austrian considers that entrepreneurs are the most important participators in the market. The standard account of Austrian Business Cycle theory posits that central bank manipulations of interest rates fool entrepreneurs into believing that there has been an increase in the real supply of funds. This induces the liqui-dation and recession at last. We use the prisoner's dilemma framework to reanalyse the profit maximizing behavior of entrepreneurs under the maximin criteria. We see that profit maximization behavior on the part of individual entrepre-neurs can explain the start of the economic boom under credit expansion.%奥地利学派的企业家精神理论认为企业家是市场中最重要的参加者。企业家是市场过程的驱动力量。奥地利商业周期理论中认为正是由于企业家受到了中央银行信贷扩张的诱导才导致集体投资不当,最后导致对不当投资的清算和萧条。本文从企业家追逐利润的本质出发,运用“囚徒困境”方法和最大最小化原则解释企业家充分考虑其他竞争者时的投资策略选择,重新对企业家行为做出分析。认为企业家追求利润最大化的目的导致了信贷扩张下经济繁荣。

    The Early Bronze Age (2.300-1.500 BC) in lower Austria consists of three synchronous regional manifestations (Únetice, Unterwölbling, and Wieselburg cultures). The bearers of these cultures inhabited a relatively small geographic area and shared similar ecological conditions, but previous studies revealed population differences in skeletal morphology. We analyzed the cranial morphology of 171 individuals of these populations with a geometric morphometric approach in order to compare different migration scenarios. We find significant mean form differences between populations and between sexes. In a principal component analysis, the Wieselburg population, located southwest of the Danube, largely separates from the Únetice population north of the Danube, whereas the southwestern Unterwölbling group, which played a central role in trading bronze objects, overlaps with both. The Böheimkirchen group, inhabiting the southwestern Danubian area in the later phase of the Early Bronze Age, differs from the chronologically older Unterwölbling group. Geographic distance between six sites and position relative to the river Danube accounted for 64% of form distance variation; the effect of the river Danube was considerably larger than hat of geographic distance per se. As predicted for a patrilocal system in which females have a larger marriage domain than males, we found that female mean forms are more similar to each other than male mean forms. Geographic conditions explained more than twice as much variation in females as in males, suggesting that female migration was more affected by geographical constraints than male migration was.

    Full Text Available Abstract Background To describe and compare visual function measures of two groups of school age children (6-14 years of age attending a specialist eyecare practice in Austria; one group referred to the practice from educational assessment centres diagnosed with reading and writing difficulties and the other, a clinical age-matched control group. Methods Retrospective clinical data from one group of subjects with reading difficulties (n = 825 and a clinical control group of subjects (n = 328 were examined. Statistical analysis was performed to determine whether any differences existed between visual function measures from each group (refractive error, visual acuity, binocular status, accommodative function and reading speed and accuracy. Results Statistical analysis using one way ANOVA demonstrated no differences between the two groups in terms of refractive error and the size or direction of heterophoria at distance (p > 0.05. Using predominately one way ANOVA and chi-square analyses, those subjects in the referred group were statistically more likely to have poorer distance visual acuity, an exophoric deviation at near, a lower amplitude of accommodation, reduced accommodative facility, reduced vergence facility, a reduced near point of convergence, a lower AC/A ratio and a slower reading speed than those in the clinical control group (p Conclusions This study highlights the high proportions of visual function anomalies in a group of children with reading difficulties in an Austrian population. It confirms the importance of a full assessment of binocular visual status in order to detect and remedy these deficits in order to prevent the visual problems continuing to impact upon educational development.

  5. Extreme heat and runoff extremes in the Swiss Alps

    2007-06-01

    Full Text Available The hydrological response of Swiss river basins to the 2003 European summer heatwave was evaluated by a combined analysis of historical discharge records and specific applications of distributed hydrological modeling. In the summer of 2003, the discharge from headwater streams of the Swiss Central Plateau was only 40%–60% of the long-term average. For alpine basins runoff was about 60%–80% of the average. Glacierized basins showed the opposite behavior. According to the degree of glacierization, the average summer runoff was close or even above average. The hydrological model PREVAH was applied for the period 1982–2005. Even if the model was not calibrated for such extreme meteorological conditions, it was well able to simulate the hydrological responses of three basins. The aridity index φ describes feedbacks between hydrological and meteorological anomalies, and was adopted as an indicator of hydrological drought. The anomalies of φ and temperature in the summer of 2003 exceeded the 1982–2005 mean by more than 2 standard deviations. Catchments without glaciers showed negative correlations between φ and discharge R. In basins with about 15% glacierization, φ and R were not correlated. River basins with higher glacier percentages showed a positive correlation between φ and R. Icemelt was positively correlated with φ and reduced the variability of discharge with larger amounts of meltwater. Runoff generation from the non-glaciated sub-areas was limited by high evapotranspiration and reduced precipitation. The 2003 summer heatwave could be a precursor to similar events in the near future. Hydrological models and further data analysis will allow the identification of the most sensitive regions where heatwaves may become a recurrent natural hazard with large environmental, social and economical impacts.

    A new species of the alpine caddisfly genus Consorophylax (Trichoptera, Limnephilidae, Stenophylacini) and the female of the recently described C. vinconi Graf & Malicky 2015 are described. The new species C. lepontiorumsp. nov. is a microendemic of the South-Western Alps and differs from its congeners in the shape of the superior and inferior appendages and the unique setation of the aedeagus, absent in all other Consorophylax species. The female of C. vinconi is characterized by the unique formation of the anal tube. Potential effects of alpine orogenesis, phenology and climatic oscillation on speciation of aquatic insects inhabiting high-altitude habitats are discussed. The description of C. lepontiorumsp. nov. accentuates the significance of the Western Alps as harbours of aquatic insect biodiversity, and demonstrates the necessity of faunal and taxonomic studies in Europe - a supposedly well-explored region.

  8. Physical modelling of baroclinic development in the lee of the Alps

    1997-06-01

    Full Text Available When baroclinic development is triggered by an obstacle, like an extended mountain range, the so-called lee, or secondary cyclogenesis can develop. The presence of the obstacle exerts a blocking effect on the lower layers of the impinging airflow, forcing them to go round its borders and reach the lee region with a delay. Blocking and delay are both responsible for the initial pressure decrease downwind of the mountain and for the subsequent proper downstream baroclinic development. According to this rather simple scheme, a cyclogenesis episode in the lee of the Alps was simulated in a hydraulic turntable. The results of these experiments showed a good agreement, both from a qualitative and quantitative point of view, with the analysis of an episode of lee cyclogenesis coupled to a cold outbreak in the Mediterranean, which actually occured in Southern Europe downstream of the Alps.

    A new species of the alpine caddisfly genus Consorophylax (Trichoptera, Limnephilidae, Stenophylacini) and the female of the recently described C. vinconi Graf & Malicky 2015 are described. The new species C. lepontiorum sp. nov. is a microendemic of the South-Western Alps and differs from its congeners in the shape of the superior and inferior appendages and the unique setation of the aedeagus, absent in all other Consorophylax species. The female of C. vinconi is characterized by the unique formation of the anal tube. Potential effects of alpine orogenesis, phenology and climatic oscillation on speciation of aquatic insects inhabiting high-altitude habitats are discussed. The description of C. lepontiorum sp. nov. accentuates the significance of the Western Alps as harbours of aquatic insect biodiversity, and demonstrates the necessity of faunal and taxonomic studies in Europe – a supposedly well-explored region.

    AlpArray is a large collaborative seismological project in Europe that includes more than 50 research institutes and seismological observatories. At the heart of the project is the collection of top-quality seismological data from a dense network of broadband temporary seismic stations, in compliment to the existing permanent networks, that ensures a homogeneous station coverage of the greater Alpine region. This Alp Array Seismic Network (AASN) began operation in January 2016 and will have a duration of at least 2 years. In this work we report the Swiss contribution to the AASN, we concentrate on the site selection process, our methods for stations installation, data quality and data management. We deployed 27 temporary broadband stations equipped with STS-2 and Trillium Compact 120 s sensors. The deployment and maintenance of the temporary stations across 5 countries is managed by ETH Zurich and it is the result of a fruitful collaboration between five institutes in Europe.

    The ALPS II experiment, Any Light Particle Search II at DESY in Hamburg, will look for light (m< 10-4 eV) new fundamental bosons (e.g., axion-like particles, hidden photons and other WISPs) in the next years by the mean of a light-shining-through-the-wall setup. The ALPS II photosensor is a Transition-Edge Sensor (TES) optimized for lambda = 1064 nm photons. The detector is routinely operated at 80 mK, allowing single infrared photon detections as well as non-dispersive spectroscopy with very low background rates. The demonstrated quantum efficiency for such TES is up to 95% at lambda =1064 nm. For 1064 nm photons, the measured background rate is < 10-2 sec-1 and the intrinsic dark count rate in a dark environment was found to be of 1,0.10-4 sec-1. Latest characterization results are discussed.

  12. Description of the larva of Protanypus sp. A (Diptera, Chironomidae from the Italian Alps

    2012-05-01

    Full Text Available We describe the larva of Protanypus sp. A from the Italian Alps. All the larval characteristics fit the diagnosis of the genus, but it is impossible to assign the specimens examined to one of the known species. The low number of labral scales (12-14 and the serrated median lamellae of the medioventral appendix of the prementum exclude the identity of the species with P. morio or with the East Palaearctic P. pseudomorio. The antennal ratio (2.3 excludes the identity with P. caudatus or P. forcipatus, which are the other two Protanypus species known from the Alpine region. In Sæther’s key (1975 the larva fits with the Nearctic P. ramosus, but identification of the species needs to be supported by pupal and adult material. In the Southern Alps, the genus is restricted to cold lakes at high altitude and is confirmed as an indicator of oligotrophic lakes.

    Surface snow samples were collected weekly from the 31st of December 2008 to the 21st of June 2009 from Lake Bramant in the French Alps. Total mercury (THg), total dissolved mercury (THgD), methylmercury (MeHg) and particle distributions in surface snow were analyzed. Results showed that THg concentrations, MeHg concentrations and particle load increased with snow surface temperature, which is an indicator of rising temperatures as the season progresses. Significant correlations between MeHg and snow surface temperature and MeHg and total particles greater than 10 μm were observed. This suggests that the MeHg found in the snow originates from atmospheric deposition processes rather than in situ snowpack sources. This study suggests that an important post-winter atmospheric deposition of MeHg and THg occurs on summital zones of the French Alps and it is likely that this contamination originates from the surrounding valleys.

    The taxonomy of Sattleria Povolný from the high mountain systems on the Balkan Peninsula and the adjacent parts of the Alps (south-eastern Alps, Dinaric Alps, Rila Mountains) is revised based on recently collected material and re-examined museum vouchers. Adult morphology and molecular data of the COI barcode region support the existence of six strictly allopatric species in this area, including four new species: Sattleria sophiae Timossi, sp. nov. (Parco Paneveggio-Pale di San Martino, Dolomites, Prov. Trento, Italy), Sattleria dolomitica Huemer, sp. nov. (Eastern Dolomites, Prov. South Tyrol, Italy), Sattleria dinarica Huemer, sp. nov. (Durmitor NP, Dinaric Alps, Montenegro) and Sattleria haemusi Huemer, sp. nov. (Rila Mts., Bulgaria; Šar Planina, Macedonia).

    Inspecting ambient noise Green's functions is an excellent tool for monitoring the quality of seismic data, and for swiftly detecting changes in the configuration of a seismological station. Those Green's functions readily provide stable information about structural variations near the Earth's surface. We apply the technique to a network consisting of about 40 broadband stations in the area of the Easternmost Alps, in particular those operated by the University of Vienna (AlpArrayAustria) and the Vienna University of Technology. Those data are used to estimate Green's functions between station pairs; the Green's function consist mainly of surface waves, and we use them to investigate crustal structure near the Eastern edge of the Alps. To obtain better signal-to-noise ratios in the noise correlation functions, we adopt a procedure using short time windows (2 hr). Energy tests are performed on the data to remove effects of transient sources and instrumental problems. The resulting 9-component correlation tensor is used to make travel time measurements on the vertical, radial and transverse components. Those measurements can be used to evaluate dispersion using frequency-time analysis for periods between 5-30 seconds. After rejecting paths without sufficient signal-to-noise ratio, we invert the velocity measurements using the Barmin et al. (2001) approach on a 10 km grid size. The obtained group velocity maps reveal complex structures with clear velocity contrasts between sedimentary basins and crystalline rocks. The Bohemian Massif and the Northern Calcareous Alps are associated with fast-velocity bodies. By contrast, the Vienna Basin presents clear low-velocity zones with group velocities down to 2 km/s at period of 7 s. The group velocities are then inverted to 3D images of shear wave speeds using the linear inversion method of Herrmann (2013). The results highlight the complex crustal structure and complement earthquake tomography studies in the region. Updated

  17. Paleogeographic significance of Upper Triassic basinal succession of the Tamar Valley, northern Julian Alps (Slovenia

    2015-08-01

    Full Text Available The Julian Alps (western Slovenia structurally belong to the eastern Southern Alps. The Upper Triassic succession mostly consists of shallow water platform carbonates of the Dolomia Principale-Dachstein Limestone system and a deep water succession of the Slovenian Basin outcropping in the southern foothills of the Julian Alps. In addition to the Slovenian Basin, a few other intraplatform basins were present, but they remain poorly researched and virtually ignored in the existing paleogeographic reconstructions of the eastern Southern Alps. Herein, we describe a deepening-upward succession from the Tamar Valley (north-western Slovenia, belonging to the Upper Triassic Tarvisio Basin. The lower, Julian-Tuvalian part of the section comprises peritidal to shallow subtidal carbonates (Conzen Dolomite and Portella Dolomite, and an intermediate carbonate-siliciclastic unit, reflecting increased terrigenous input and storm-influenced deposition (Julian-lowermost Tuvalian shallow-water marlstone and marly limestone of the Tor Formation. Above the drowning unconformity at the top of the Portella Dolomite, Tuvalian well-bedded dolomite with claystone intercalations follows (Carnitza Formation. The latter gradually passes into the uppermost Tuvalian–lowermost Rhaetian bedded dolomite with chert and slump breccias, deposited on a slope and/or at the toe-of-slope (Bača Dolomite. Finally, basinal thin-bedded bituminous limestone and marlstone of Rhaetian age follow (Frauenkogel Formation. The upper part of the Frauenkogel Formation contains meter-scale platform-derived limestone blocks, which are signs of platform progradation. The Tarvisio Basin may have extended as far as the present Santo Stefano di Cadore area, representing a notable paleogeographic unit at the western Neotethys margin.

    We investigated the Sachette rock glacier, Vanoise Massif, Northern French Alps, using former equilibrium line altitude reconstruction from glacial deposits, aerial photograph analysis, and ground-penetrating radar (GPR). The rock glacier is a young (probably 0.15–0.16 m ns−1) and reflectors having a dipping-syncline structure, typical of true glaciers. Consequently, the rock glacier structure is described as being constituted of ...

    Background: young persons are most strongly affected by displacement through political/military actions. This is also a European problem as well as an issue for the European Union. Applying the social-ecological model by Bronfenbrenner we concentrated on micro- and mesosystems of Austrian adolescents and migrant adolescents of war-affected countries.

    Methods: a questionnaire was administered to adolescents in Austria attending schools beyond the mandatory school age, yielding a sample of about 1 100 students from Austrian and immigrant background. We used analysis of variance to compare host and immigrant youth as well as regression analysis to assess the impact of risk and protective factors on youth outcomes.

    Results: we do find sex differences for protective factors and youth outcomes but few differences between immigrant and Austrian adolescents. Youth outcomes analysed were somatic symptoms, anxiety, depression, self-esteem, anti-social behaviour, substance use, and academic performance. Important risk factors turned out to be intergenerational conflict, exposure to violence, and social distance. Protective factors include family connectedness, parental monitoring, school connectedness, peer support, and neighbourhood attachment.

    Conclusions: the most important protective factor is school connectsdness. Social distance and intergenerational conflict are the dominant risk factors influencing youth outcomes. Our research leads to a better understanding of factors determining the well-being of adolescents and contributes to finding new approaches to prevent or cope with mental health problems of young immigrants. In particular it appears to be important to keep young persons in education and/or training since school connectedness influences mental health and well-being positively.

  20. Beyond the Alps? Tyrolean and Carinthian historians between large and small homelands

    Directory of Open Access Journals (Sweden)

    Giuseppe Albertoni

    2015-05-01

    Full Text Available This essay examines the relationship between medieval studies, “local patriotism” and nationalism in Tyrol and in Carinthia from the second half of the nineteenth century to the First World War. In this context, the work of historians who studied at the Austrian Institute of Historical Research (e.g. A. von Jaksch is examined, in particular their research into and application of an historical-critical method that, at the local level, united philology with a strong patriotic sentiment. The essay examines in particular the case of the edition of Carinthian and Tyrolean medieval sources such as Monumenta Historica Ducatus Carinthiae and the Tiroler Urkundenbuch. These linked the present to the medieval past through a “document genealogy” which unified the past and contributed to the construction of regional political identities.

    Highlights: • We report the dielectric function ε of AlP from 0.74 to 6.54 eV. • The critical points (CPs) in the E{sub 2} spectral range are important for band-structure analysis. • We extract ε of AlP, using the multilayer parametric model. • The CP energies are obtained from numerically calculated second-energy-derivatives. • We identify these CPs from the linear augmented Slater-type orbital method. -- Abstract: We report the room-temperature dielectric function ε of AlP from 0.74 to 6.54 eV obtained by in situ spectroscopic ellipsometry. Measurements were done on a 1.2 μm thick film grown on (0 0 1) GaAs by molecular beam epitaxy, with ε extracted using a multilayer parametric model. Critical point energies of features in the ε spectra were obtained from numerically calculated second-energy-derivatives, and their Brillouin-zone origins identified by band-structure calculations done using the linear augmented Slater-type orbital method.

    Autoimmune diseases develop in approximately 5% of humans. They can arise when self-tolerance checkpoints of the immune system are bypassed as a consequence of inherited mutations of key genes involved in lymphocyte activation, survival, or death. For example, autoimmune lymphoproliferative syndrome (ALPS) results from defects in self-tolerance checkpoints as a consequence of mutations in the death receptor-encoding gene TNF receptor superfamily, member 6 (TNFRSF6; also known as FAS). However, some mutation carriers remain asymptomatic throughout life. We have now demonstrated in 7 ALPS patients that the disease develops as a consequence of an inherited TNFRSF6 heterozygous mutation combined with a somatic genetic event in the second TNFRSF6 allele. Analysis of the patients' CD4(-)CD8(-) (double negative) T cells--accumulation of which is a hallmark of ALPS--revealed that in these cells, 3 patients had somatic mutations in their second TNFRSF6 allele, while 4 patients had loss of heterozygosity by telomeric uniparental disomy of chromosome 10. This observation provides the molecular bases of a nonmalignant autoimmune disease development in humans and may shed light on the mechanism underlying the occurrence of other autoimmune diseases.

    The AlpArray initiative (http://www.alparray.ethz.ch) is a large-scale European collaboration to study the entire Alpine orogen at high resolution and in 3D with a large variety of geoscientific methods. The core element of the initiative is an extensive and dense broadband seismological network, the AlpArray Seismic Network (AASN), which complements the permanent seismological stations to ensure homogeneous coverage of the greater Alpine area. The some 260 temporary stations of the AlpArray Seismic Network are operated as a joint effort by a number of institutions from Austria, Bosnia-Herzegovina, Croatia, Czech Republic, France, Germany, Hungary, Italy, Slovakia and Switzerland. The first stations were installed in Spring 2015 and the full AASN is planned to be operational by early Summer 2016. In this poster we present the actual status of the deployment, the effort undertaken by the contributing groups, station performance, typical noise levels, best practices in installation as well as in data management, often encountered challenges, and planned next steps including the deployment of ocean bottom seismometers in the Ligurian Sea.

  4. Seismic signature of the Alpine indentation, evidence from the Eastern Alps

    The type of collision between the European and the Adriatic plates in the easternmost Alps is one of the most interesting questions regarding the Alpine evolution. Tectonic processes such as compression, escape and uplift are interconnected and shape this area. We can understand these ongoing processes better, if we look for signs of the deformation within the Earth's deep crust of the region. By collecting records from permanent and temporary seismic networks, we assemble a receiver function dataset, and analyze it with the aim of giving new insights on the structure of the lower crust and of the shallow portion of the upper mantle, which are inaccessible to direct observation. Imaging is accomplished by performing common conversion depth stacks along three profiles that crosscut the Eastern Alpine orogen, and allow isolating features consistently persistent in the area. The study shows a moderately flat Moho underlying a seismically anisotropic middle-lower crust from the Southern Alps to the Austroalpine nappes. The spatial progression of anisotropic axes reflects the orientation of the relative motion and of the stress field detected at the surface. These observations suggest that distributed deformation is due to the effect of the Alpine indentation. In the shallow upper mantle right below the Moho interface, a further anisotropic layer is recognized, extended from the Bohemian Massif to the Northern Calcareous Alps.

  5. Encounters between Alpine ibex, Alpine chamois and domestic sheep in the Swiss Alps

    2002-12-01

    Full Text Available Abstract Information regarding spatio-temporal relationships and encounters of sympatric domestic sheep, Alpine ibex (Capra ibex ibex and Alpine chamois (Rupicapra rupicapra rupicapra in the Swiss Alps were systematically registered to evaluate the possibility of an interspecific transmission of infectious agents on pastures. Observations were performed in alpine regions of four Swiss cantons during the 1997 and 1998 mountain summer grazing season. In the main study area, Val Chamuera (canton of Grisons, a consistent reduction in the number of ibexes was observed after the arrival of sheep on the pasture. Some ibexes remained for a longer time in the area, but in general, ibexes and sheep did not use the same compartments of the area simultaneously. However, a salt lick for sheep attracted the ibexes, and several encounters were recorded in the compartments close to this salt lick. Several encounters registered in other areas of the Swiss Alps also occurred in the neighbourhood of a salt lick; however, in other cases different species were attracted by rich pastures. The study indicates that encounters (0-50 m between free-ranging individuals of different Caprinae species, domestic and wild, are not uncommon events in the Alps. Therefore, encounters can be considered to be a predisposing factor for interspecific transmission of infectious agents such as Mycoplasma conjunctivae, causing keratoconjunctivitis in chamois, ibex, domestic sheep and goats.

    Ragweed in France is a rather recent pollen which causes strong allergies on the populations concerned. This pollen, mainly located in the area Rhone-Alpes, extend more and more on totality of France. Indeed, the pollinic data highlight the presence of ragweed on all the territory with very low, as for Brittany, to several hundreds grains in the area of Rhone-Alpes. So four towns of this area have followed closely the extend of this pollen during the year 2002 through five pollen-traps (2 for the town of Lyon). The trap of Lyon I (Gerland) made it possible to follow temporal the extend of ragweed from 1987 to 2002 and the increase of the number of grains as that of the number of days with a significant allergic risk. The study shows also the differences in quantity of pollens, the differences between the daily allergic risks of the five sites, as well as the differences, between the cities, of the number of days when the allergic risk is significant. It is necessary that pollen of ragweed can be followed closely because of its strong allergenic capacity, in the area of Rhone-Alpes, where the plant prevails mainly, but also on the totality of the own territory, this to supervise its evolution and the speed of proliferation of the plant.

    Full Text Available Analysis of the internal characters, especially the cardinalia and brachidium, of the brachiopod Comelicania Frech from the Southern Alps, confirmed the attribution of this genus to the Superfam. Athyridoidea Davidson and provided a more complete taxonomic description of the Fam. Comelicaniidae Merla. This family includes two genera which differ in the morphology of their cardinalia, i.e. Gruntallina Waterhouse & Gupta, type-species Gruntallina triangularis (Grunt from the lower Dorashamian of Transcaucasia and Comelicania, type-species Comelicania megalotis (Stache from the uppermost Bellerophon Fm. of the Southern Alps. The study of a collection composed of more than a hundred specimens highlighted a broad variability of the morphological characters and a pattern of ontogenetic development which demonstrates that classification at the species level is possible only when using mature specimens. Taxonomic revision at the specific level reduced the eleven species of Comelicania from the Southern Alps, described by previous authors, to: C. megalotis (Stache and C. haueri (Stache. In addition a new species, C. merlai, which characterises the upper Comelicania beds, is proposed.

    The health care facility "Breitenstein" makes use of a hospital information system to coordinate clinical processes and document medical health data. So as to comply with novel Austrian legislation and fit the "ELGA" architecture, the system has to be adapted. This paper is based on a literature research and gives answers to technical and legal aspects of "ELGA". The introduction of an IHE connector and a CDA manager are the main changes to the current hospital information system. The implementation of interfaces that allow an integration of further "ELGA" features possible are the next step of the project.

  9. Large outbreaks of Ips acuminatus in Scots pine stands of the Italian Alps

    Full Text Available In the last years, many Scots pine (Pinus sylvestris stands have been severely attacked by the bark beetle Ips acuminatus (Coleoptera Curculionidae Scolytinae. In the outbreak area of San Vito di Cadore (Eastern Dolomites, the number of attacked trees since 2005 and both the emergence of bark beetles and natural enemies have been assessed. The investigated forests showed dozens of easily recognizable infestation spots with size ranging from about 20-30 trees (small spots up to 300 trees (large spots. These infested spots evolved quickly, while new ones appeared within a radius of few hundreds of meters. During the last 5 years (2006-2010 we sampled branches from small and large spots and lodged them into emergence cages: adults of I. acuminatus as well as natural enemies were collected weekly, identified and counted. At the same time, a monitoring program of the surveyed pine stands was carried out to check the enlargement of old spots and the appearance of new ones. Voltinism and phenology of I. acuminatus were investigated by pheromone traps baited with different lures (Austrian vs. Spanish lures. The effects of a sanitation felling of about 4500 infested trees, carried out by the Regional Forest Service in autumn 2007 on I. acuminatus population were also assessed. Throughout the whole sampling area I. acuminatus resulted bivoltine, with the highest density attained during the first generation. However, a part of the population still evidenced a monovoltine behaviour. The realized sanitation felling strongly reduced both breeding sites and the number of infested trees observed during the following year. Moreover the pheromone-baited traps gave useful information about changes in bark beetle population density; the trapping efficiency of Spanish lure resulted clearly higher than the Austrian one. Finally, the recorded parasitism may have a role in outbreak dynamics as it was significantly higher during the second host generation, in both small

    The heterogeneous nucleation of primary Si and eutectic Si can be attributed to the presence of AlP. Although P, in the form of AlP particles, is usually observed in the centre of primary Si, there is still a lack of detailed investigations on the distribution of P within primary Si and eutectic Si in hypereutectic Al-Si alloys at the atomic scale. Here, we report an atomic-scale experimental investigation on the distribution of P in hypereutectic Al-Si alloys. P, in the form of AlP particles, was observed in the centre of primary Si. However, no significant amount of P was detected within primary Si, eutectic Si and the Al matrix. Instead, P was observed at the interface between the Al matrix and eutectic Si, strongly indicating that P, in the form of AlP particles (or AlP 'patch' dependent on the P concentration), may have nucleated on the surface of the Al matrix and thereby enhanced the heterogeneous nucleation of eutectic Si. The present investigation reveals some novel insights into heterogeneous nucleation of primary Si and eutectic Si by AlP in hypereutectic Al-Si alloys and can be used to further develop heterogeneous nucleation mechanisms based on adsorption.

    Full Text Available Abstract Background The PDZ-LIM proteins are a family of signalling adaptors that interact with the actin cross-linking protein, α-actinin, via their PDZ domains or via internal regions between the PDZ and LIM domains. Three of the PDZ-LIM proteins have a conserved 26-residue ZM motif in the internal region, but the structure of the internal region is unknown. Results In this study, using circular dichroism and nuclear magnetic resonance (NMR, we showed that the ALP internal region (residues 107–273 was largely unfolded in solution, but was able to interact with the α-actinin rod domain in vitro, and to co-localize with α-actinin on stress fibres in vivo. NMR analysis revealed that the titration of ALP with the α-actinin rod domain induces stabilization of ALP. A synthetic peptide (residues 175–196 that contained the N-terminal half of the ZM motif was found to interact directly with the α-actinin rod domain in surface plasmon resonance (SPR measurements. Short deletions at or before the ZM motif abrogated the localization of ALP to actin stress fibres. Conclusion The internal region of ALP appeared to be largely unstructured but functional. The ZM motif defined part of the interaction surface between ALP and the α-actinin rod domain.

    Sultan Alp Arslan (1029-1072) was the second Sultan of the Seljuq Empire and great-grandson of Seljuq the eponymous founder of the dynasty. Sultan Alp Arslan's victories changed the balance in near Asia completely in favour of the Seljuq Turks and Sunni Muslims. His victory at Manzikert (26 August 1071) is often cited as the beginning of the end of Byzantine power in Anatolia, and the beginning of Turkish identity in Anatolia. Sultan Alp Arslan eliminated theobstacles to the conquest of Anatolia and played a major role in making this territory a homeland for the Seljuqs. By taking the Emperor captive, Sultan Alp Arslan gained great fame but in 1072, on an expedition to Western Turkestan, he met with death in an unexpected way and at a relatively early age, in his 42nd year. There have been found different stories of the death of this great Turkish Sultan in certain sources. Unfortunately, there has not been found The Sultan's resting place until now. This paper is concerned with the investigation of the Sultan Alp Arslan Tomb in the historical Merv (Marv) city in Turkestan, by using Ground Penetrating Radar (GPR) and gradiometer methods. The GPR and gradiometer surveys have been realized in Gavur Fortress, Sultan Fortress, Er Fortress districts and between two big Fortresses in old Merv city in selected nine study areas. We also gathered data in and around Sultan Sancar Tomb. GPR surveys were performed during January 2014 employing Ramac CU-II system equipped with a 250 MHz shielded antenna, on one meter spaced profiles. Similarly a Geoscan system was used to take magnetic data. The results of all these investigation revealed that there were possible traces for the buried tomb of the Sultan Alparslan in Gavur Kale around Cuma Mosque and around Sultan Sancar Tomb in the study region. However, the project team was changed after our study, and the new team did not excavated our determined areas. Acknowledgement This project has been supported by Republic of Turkey

    Mountain areas are particularly vulnerable to climate change. Owing to the complexity of mountain terrain, climate research at scales relevant for impacts studies and decisive for stakeholders is challenging. A possible way to bridge the gap between these fine scales and those of the general circulation models (GCMs) consists of combining high-resolution simulations of Regional Climate Models (RCMs) to statistical downscaling methods. The present work is based on such an approach. It aims at investigating the impacts of climate change on snow cover in the French Alps for the periods 2021-2050 and 2071-2100 under several IPCC hypotheses. An analogue method based on high resolution atmospheric fields from various RCMs and climate reanalyses is used to simulate local climate scenarios. These scenarios, which provide meteorological parameters relevant for snowpack evolution, subsequently feed the CROCUS snow model. In these simulations, various sources of uncertainties are thus considered (several greenhouse gases emission scenarios and RCMs). Results are obtained for different regions of the French Alps at various altitudes. For all scenarios, temperature increase is relatively uniform over the Alps. This regional warming is larger than that generally modeled at the global scale (IPCC, 2007), and particularly strong in summer. Annual precipitation amounts seem to decrease, mainly as a result of decreasing precipitation trends in summer and fall. As a result of these climatic evolutions, there is a general decrease of the mean winter snow depth and seasonal snow duration for all massifs. Winter snow depths are particularly reduced in the Northern Alps. However, the impact on seasonal snow duration is more significant in the Southern and Extreme Southern Alps, since these regions are already characterized by small winter snow depths at low elevations.

    From the earliest days of geological science, mountainous terrains with their extreme topographic relief and sparse to non-existent vegetation were utilized to a great advantage for gaining 3D insight into geological structure. But whereas Alpine vistas may offer perfect panoramic views of geology, the steep mountain slopes and vertical cliffs make it very time-consuming and difficult (if not impossible) to acquire quantitative mapping data such as precisely georeferenced traces of geological boundaries and attitudes of structural planes. We faced this problem in mapping the central Kamnik Alps of northern Slovenia, which are built up from Mid to Late Triassic succession of carbonate rocks. Polyphase brittle tectonic evolution, monotonous lithology and the presence of temporally and spatially irregular facies boundary between bedded platform carbonates and massive reef limestones considerably complicate the structural interpretation of otherwise perfectly exposed, but hardly accessible massif. We used Agisoft Photoscan Structure-from-Motion photogrammetric software to process a series of overlapping high-resolution (~0.25 m ground resolution) vertical aerial photographs originally acquired by the Geodetic Authority of the Republic of Slovenia for surveying purposes, to derive very detailed 3D triangular mesh models of terrain and associated photographic textures. Phototextures are crucial for geological interpretation of the models as they provide additional levels of detail and lithological information which is not resolvable from geometrical mesh models alone. We then exported the models to Paradigm Gocad software to refine and optimize the meshing. Structural interpretation of the models, including mapping of traces and surfaces of faults and stratigraphic boundaries and determining dips of structural planes, was performed in MVE Move suite which offers a range of useful tools for digital mapping and interpretation. Photogrammetric model was complemented by

    Active deformation at the boundary between the Eurasia and Africa plates varies in style. The belt between the Alpine mountain range and the Mediterranean Sea, for example, differs markedly in its western and eastern parts. In the western part, around southeast France, the mountains are higher, but the seismicity lower, than in the eastern part, around northern Italy and Greece. Yet the inter-plate convergence rate of 6 mm/yr varies by less than 15% between these two areas. To better understand the behaviour of this complex plate boundary, we use geodesy to map the spatial distribution of the deformation. In this paper, we focus on southeast France, a tectonic crossroads between three different domains (Alps, Ligurian Sea, and Massif Central) which exhibits a moderate level of seismicity. Here, the geodetic measurements imply low rates of horizontal deformation. By combining historical triangulation measurements mostly from 1947 to 1983 with Global Positioning System (GPS) surveys in 1993 and 1994, we estimate the rate of angular shear in triangular subnetworks covering the study area. The estimated strain rates in thirteen of nineteen triangles are smaller than their (1 standard deviation) uncertainties of about 0.1 microradian/yr. This value bounds the rate of deformation for a 100-km wide zone in Provence, between Marseilles to the south and the Ventoux massif to the north. The geodetic estimates place an upper bound of 1 to 2 mm/yr on the slip rates of two seismically active structures, the Durance fault and the Nı̂mes fault, assuming a fault zone ˜20 km wide in each case. We also find strain rates as high as 0.20±0.07 microradian/yr in three subnetworks near the epicentre of the magnitude 5.3 Haute-Ubaye earthquake in 1959, in a region which includes the higher summits. This may be interpreted either as pure shear with compression oriented NE-SW across this region or right-lateral simple shear along NNW-SSE-trending faults. Given that this earthquake is

    Full Text Available Introduction: For some patients, it remains a challenge to achieve complete virological suppression which is the goal of antiretroviral therapy (ART. Identifying factors associated with low-level viraemia (LLV and virological failure (VF under ART might help to optimize management of these patients. Materials and Methods: We investigated patients from the Austrian HIV Cohort Study receiving unmodified ART for >6 months with two nucleoside reverse-transcriptase inhibitors (NRTIs with either a non-nucleoside reverse-transcriptase inhibitor (NNRTI or a boosted protease inhibitor (PI or an integrase inhibitor (INSTI between 1 July 2012 and 1 July 2013 with at least one viral load (VL measurement below the limit of detection (BLD or below level of quantification (BLQ in their treatment history. VF was defined as HIV-RNA levels ≥200 copies/mL and all other quantifiable measurements were classified as LLV. Factors associated with LLV and VF compared to BLD and BLQ were identified by using logistic regression models. Results: Of the 2,276 patients analyzed, 1,972 (86.6% were BLD or BLQ, 222 (9.8% showed LLV and 82 (3.6% had VF. A higher risk for LLV and VF was found in patients with ART interruptions and in patients with boosted PI therapy. The risk for LLV and VF was lower in patients from a centre which uses Abbott RealTime HIV-1 assay compared to the other centres measuring VL by the Roche Cobas AmpliPrep/Cobas TaqMan 2.0. A higher risk for LLV but not for VF was found in patients with a higher VL before ART and shorter ART duration. A higher risk for VF but not for LLV was found in patients of younger age, originating from a high prevalence country, with a lower CD4 count and in male injecting drug users. Conclusions: This study of well-defined patients on stable ART over a period of more than six months gives insights into the different factors associated with LLV and VF. In patients with VF, factors associated with adherence play a prominent

Annette Haberl (HIV-Department, J. W. Goethe-University Hospital, Frankfurt, Dr. med. Brigitte Schmied (Otto-Wagner Spital, Wien. In Germany during the last years about 200-250 HIV1-infected pregnant women delivered a baby each year, a number that is currently increasing. To determine the HIV-status early in pregnancy voluntary HIV-testing of all pregnant women is recommended in Germany and Austria as part of prenatal care. In those cases, where HIV1-infection was known during pregnancy, since 1995 the rate of vertical transmission of HIV1 was reduced to 1-2%. This low transmission rate has been achieved by the combination of anti-retroviral therapy of pregnant women, caesarean section scheduled before onset of labour, anti-retroviral post exposition prophylaxis in the newborn and refraining from breast-feeding by the HIV1-infected mother. To keep pace with new results in research, approval of new anti-retroviral drugs and changes in the general treatment recommendations for HIV1-infected adults, in 1998, 2001, 2003 and 2005 an interdisciplinary consensus meeting was held. Gynaecologists, infectious disease specialists, paediatricians, pharmacologists, virologists and members of the German AIDS Hilfe (NGO were participating in this conference to update the prevention strategies. A fifth update became necessary in 2008. The updating process was started in January 2008 and was terminated in September 2008. The guidelines provide new recommendations on the indication and the starting point for HIV-therapy in pregnancies without complications, drugs and drug combinations to be

    The development of lameness is influenced by a number of different factors (housing, management, human-animal relationship and animal-related parameters). The aim of this study was to investigate the effects of the complex interactions of these aspects and to search for the relative importance of single factors. In 80 dairy herds of Austrian Simmental cows housed in cubicle loose housing in Upper and Lower Austria, risk factors for lameness, selected from the four factor groups housing, management, human-animal relationship and animal-related variables, were investigated during one farm visit in the autumn and winter months. To assess their relative importance, a multivariable analysis (regression trees) was calculated. The most important risk factor for lameness was the lying surface: straw bedding of at least 2 cm thickness or cow-comfort mats were associated with a lower percentage of lame cows. In case of insufficient quality of the lying surface, the next important parameter identified was the position of the neck rail: a neck rail diagonal greater than 1.94 m was associated with a lower percentage of lame cows. By contrast, on farms with high-quality lying surfaces, lameness prevalence was lower when at least parts of the alleys were constructed with solid floor and not slatted. Further variables associated with a low prevalence of lameness were a longer time span between calving and separation of the calf from the dam, the existence of an outside run, a lower percentage of fat cows, a greater space allowance, more cubicles than animals and a lower kerb height. In addition, further management factors such as the way in which heifers are integrated into the herd or management decisions taking into account the cows' welfare were related to less lameness. Human-animal relationship variables such as, for example, the behaviour and attitude of the stockpeople were explaining variables. In sum, important risk factors were found in all factor groups. Therefore it is

    Full Text Available The Monte Corchia cave system, one of the most famous and popular caves in Italy, has in recent times been the subject of investigation on its speleothems as paleoclimate archives. This paper describes the geology, geomorphology and water chemistry of the cave system with the aim to elucidate the processes that have generated these speleothems and the properties they contain that are so useful for paleoclimatology. Some general conclusions can be drawn: i the Corchia system is a cave developed over different altitudes during progressive uplift of the mountain chain in which it is located, probably under drainage conditions very different to those of the present. This has allowed the development of a large (ca. 60 km and deep (-1187 m karst system; ii the dewatering phases have left the deepest chambers far away from clastic input and with long drip pathways; iii the peculiar geological context has permitted the water to intercept and dissolve a significant source of U (still unknown that facilitates radiometric dating; iv in the last 1 Ma at least, no significant changes have occurred in the relief and in the epikarst, in the sense that speleothems have grown under very similar conditions. In addition the extremely low Ca concentration of drip waters have permitted low speleothem growth rates and, at least for the “Galleria delle Stalattiti”, the zone under paleoclimate studies,a stable plumbing system (i.e. chemistry and stable isotopes of drip waters has produced calcite close to isotopic equilibrium.

    Full Text Available The dynamic model MAGIC was calibrated and applied to selected sites in north-western Italy (3 rivers, 10 alpine lakes to predict the future response of surface water to different scenarios of atmospheric deposition of S and N compounds. Results at the study sites suggest that several factors other than atmospheric deposition may influence the long-term changes in surface water chemistry. At present the lumped approach of dynamic models such as MAGIC cannot represent all the processes occurring at the catchment scale. Climate warming in particular and its effects on surface water chemistry proved to be important in the study area. Furthermore the river catchments considered here showed clear signs of N saturation. This condition and the increasing concentrations of NO3 in river water were simulated using N dynamics recently included in MAGIC. The modelling performed in this study represents the first application of MAGIC to Italian sites. The results show that inclusion of other factors specific to the Mediterranean area, such as dust deposition and climate change, may improve the fit to observed data and the reliability of the model forecast. Despite these limitations, the model captured well the main trends in chemical data in both rivers and lakes. The outputs clearly demonstrate the benefits of achieving the emission reductions in both S and N compounds as agreed under the Gothenburg Protocol rather than making no further emission reductions. It was also clear that, besides the substantial reduction of SO4 deposition from the peak levels of the 1980s, N deposition must also be reduced in the near future to protect freshwaters from further acidification.

The objective of the project is to provide INTA with a new standard that covers the dew-point temperature range from - 27°C to +90°C with a gas flow up to 5 L· min-1 in the “two-pressure” mode, extended to 95°C when operated as a continuous flow “single-pressure” generator, and investigate the importance of the enhancement factors in the uncertainty estimations used in support of the participants’ calibration and measurement capabilities (CMC) (The CIPM Mutual Recognition Arrangement, http://www.bipm.fr/en/cipm-mra/ ). The equivalence of the Spanish and Austrian national standards is also to be evaluated, further supporting the outcomes of the Key Comparisons, in which both have already participated. The preliminary results obtained to date are reported and discussed in the context of the project and the consistency of the declared CMC’s.

    Mountain lakes represent essential stages for aquatic species on their way colonizing habitats of more elevated regions.Despite extensive biological and chemical study,only little has been reported about the species number and density of freshwater molluscs in these waters.The article presented here elucidates the dispersal of aquatic gastropods and bivalves in 12 mountain lakes that are commonly situated in the Eastern Alps,Austria.Molluscs were recorded at 120 sample points,where a total of 13 species (8 gastropods and 5 bivalves) could be determined.Species distribution data as well as results from contemporarily conducted physico-chemical factor recording were subject to weighted average analysis.In addition,a global marginality coefficient indicating the particularity of a habitat inhabited by a focal species as well as a global tolerance coefficient expressing the width of a niche occupied by this species were computed.Species-environment relationships exhibited that species number and specific density decrease with increasing geographic altitude,declining water temperature,and decreasing amount of submerged vegetation.Whilst waters of the montane altitude level are partly charcterized by high number of mollusc species (>10),lakes of the subalpine altitude level commonly bear 1 or 2 species with <<1 ind./m2.As proposed by the results of statistics,9 of the 13 mollusc species are characterized by a pronounced behaviour as specialists with respect to most environmental factors.The four remaining species,Pisidium casertanum,Galba truncatula,Radix labiata,and Radix balthica,act as generalists which increases their pioneering role in the long-term occupation of the Central-alpine region.

    The Eastern Alpine Seismic Investigation (EASI) was a complementary experiment to the AlpArray project. EASI was composed of 55 broadband seismic stations deployed in a winding swath of 540 km length along longitude 13.350 E from the Czech-German border to the Adriatic Sea. Average north-south inter-station distance was 10 km, the distance of each station to either side of the central line was 6 km. Such a dense linear network allows for surface wave dispersion measurements by both deterministic and ambient noise sources along the same paths. During the experiment (July 2014 - August 2015), three earthquakes ML = 2.6, 2.9 and 4.2 occurred in Austria and Northern Italy only several kilometers off the swath. We measure Rayleigh and Love wave group velocities between the source and a single station for the recorded earthquakes, as well as phase velocities between selected pairs of stations using the standard two-station method. We also calculate cross-correlations of ambient noise between selected pairs of stations and we determine the corresponding group velocity dispersion curves. We propose a comparison of phase velocities between two stations measured from earthquakes with group velocities obtained from cross-correlations for the same station pairs. We also compare group velocities measured at single station using earthquakes, which occurred along the swath, with group velocities measured from cross-correlations. That way we analyze velocities of both deterministic and ambient noise reconstructed surface waves propagating along the same path. We invert the resulting dispersion curves for 1D shear wave velocity profiles with depth and we compile a quasi-2D velocity model along the EASI swath.

    considered as a sort of pseudo-stratigraphy, since they are the oldest feature that can be traced continuously at the map scale. For this reason we have developed a set of attributes identifying the tectonic and lithological units (a "legend"), implemented both in the GIS database and in the 3D models, which at the same time is compatible with the data structure of 3D modelling packages like Move and Skua/Gocad, and allows tracing the complex hierarchic classification of the units mapped in the GIS. This allows for the almost automatic and consistent two-way transfer of data between the GIS and geomodelling environments. E.g. results of 3D modelling, which is based on input data originally stored in the GIS, will eventually be transferred back to the GIS. The results of this study, which are preliminarily presented here, will open new opportunities to study the collision- and subduction-related nappe architecture and kinematics with younger deformations removed, and will eventually lead (with additional studies) to a step-by-step retrodeformation supported by modern technologies, following the path traced by Argand at the beginning of the 20th century.

    We present numerically the ferromagnetic and spin-resolved electronic properties of Ti-doped AlP system by using first principle based on spin density functional theory. It is found that Ti impurities are spin-polarized, and it suggests a 100% polarization of the conduction carriers from the calculated band structures. Besides, the net magnetic moment of about 1 μ{sub B} per Ti is demonstrated. The ferromagnetic state of 115.7 meV per Ti atom, lower than the anti-ferromagnetic state, is obtained by total energy calculation for both GGA and GGA+U method. And the Curie temperature, higher than 599 K, in Ti-doped AlP is predicted using mean-field approximation (MFA) theory. Both double-exchange and p–d hybridization mechanism contribute to the ferromagnetic ground state of Ti-doped AlP, but the former is dominant. Therefore, it is expected that Ti-doped AlP would be a promising dilute magnetic semiconductor for the applications in the field of Spintronics. - Highlights: • It is found that Ti impurities are spin-polarized, and it suggests a 100% polarization of the conduction carriers for Ti doped AlP. • The Curie temperature, higher than 599 K in Ti-doped AlP is predicted using mean-field approximation (MFA) theory and first principles method combinational with Monte Carlo method. • The double-exchange and p–d hybridization mechanism are also used to explain the ferromagnetic ground state of Ti-doped AlP.

    Full Text Available The Apuan Alps region is one of the rainiest areas in Italy (more than 3000 mm/year, in which frequently heavy and concentrated rainfall occurs. This is particularly due to its geographical position and conformation: the Apuan chain is located along the northern Tuscan coast, close to the Ligurian Sea, and the main peaks reach almost 2000 m. In several cases, the storms that hit the area have triggered many shallow landslides (soil slip-debris flows, which exposed the population to serious risks (during the 19 June 1996 rainstorm about 1000 landslides were triggered and 14 people died. The assessment of the rainfall thresholds is very important in order to prepare efficient alarm systems in a region particularly dedicated to tourism and marble activities. With the aim of contributing to the landslide hazard evaluation of the southern Apuan Alps territory (upper Versilia area, a detailed analysis of the main pluviometric events was carried out. The data recorded at the main rain gauge of the area from 1975 to 2002 were analysed and compared with the occurrence of soil slips, in order to examine the relationship between soil slip initiation and rainfall. The most important rainstorms which triggered shallow landslides occurred in 1984, 1992, 1994, 1996, 1998 and 2000. Many attempts were made to obtain a possible correlation between rainfall parameters and the occurrence of soil slip phenomena and to identify the local rainfall threshold for triggering shallow landslides. A threshold for soil slip activity in terms of mean intensity, duration and mean annual precipitation (MAP was defined for the study area. The thresholds obtained for the southern Apuan Alps were also compared with those proposed by other authors for several regions in the world. This emphasized the high value of the rain threshold for shallow landslide activity in the Apuan area. The high threshold is probably also linked to the high mean annual precipitation and to the high

    A comprehensively 14C AMS dated pollen and chironomid record from Boundary Stream Tarn provides the first chironomid-derived temperature reconstruction to quantify temperature change during Lateglacial times (17,500–10,000 cal yr BP) in the Southern Alps, New Zealand. The records indicate a ca 1000-year disruption to the Lateglacial warming trend and an overall cooling consistent with the Antarctic Cold Reversal (ACR).

  10. Possible environmental effects on the evolution of the Alps-Molasse basin system

    We propose three partly unrelated stages in the geodynamic evolution of the Alps and the sedimentary response of the Molasse Basin. The first stage comprises the time interval between ca. 35 and 20 Ma and is characterized by a high ratio between rates of crustal accretion and surface erosion. The response of the Molasse Basin was a change from the stage of basin underfill (UMM) to overfill (USM). Because the response time of erosional processes to crustal accretion and surface uplift lasts several millions of years, the orogen first experienced a net growth until the end of the Oligocene. As a result, the Molasse basin subsided at high rates causing the topographic axis to shift to the proximal basin border and alluvial fans to establish at the thrust front. During the Aquitanian, however, ongoing erosion and downcutting in the hinterland caused sediment discharge to the basin to increase and the ratio between the rates of crustal accretion and surface erosion to decrease. The result was a progradation of the dispersal systems, and a shift of the topographic axis towards the distal basin border. The second stage started at ca. 20 Ma at a time when palaeoclimate became more continental, and when the crystalline core became exposed in the orogen. The effect was a decrease in the erosional efficiency of the Swiss Alps and hence a reduction of sediment discharge to the Molasse Basin. We propose that this decrease in sediment flux caused the Burdigalian transgression of the OMM. We also speculate that this reduction of surface erosion initiated the modification of Alpine deformation from vertically- to mainly horizontally directed extrusion (deformation of the Southern Alps, and the Jura Mountains some Ma later). The third stage in the geodynamic development was initiated at the Miocene/Pliocene boundary. At that time, palaeoclimate possibly became wetter, which, in turn, caused surface erosion to increase relative to crustal accretion. This change caused the Alps to

    In an introductory section the problems of constructing a geologic time scale and the role of magnetic reversals and Milankovitch cycles in geochronology are outlined. Results of a detailed cyclostratigraphic and magnetostratigraphic study of the Valanginian/Hauterivian part of the pelagic limestone section at Cismon in the Southern Alps are presented and used in conjunction to estimate the duration of magnetic subchrons between CM10N and CM8. The new estimates are shorter than in most published time scales by a factor of two to three. More research along these lines may make a revision of the Early Cretaceous time scale necessary. ?? 1994 International Association for Mathematical Geology.

    Sze, D.-K.

    1999-07-08

    A Sn-Li alloy has been identified to be a coolant/breeding material for D-T fusion applications. The key feature of this material is its very low vapor pressure, which will be very useful for free surface concepts employed in APEX, ALPS and inertial confinement fission. The vapor is dominated by lithium, which has very low Z. Initial assessment of the material indicates acceptable tritium breeding capability, high thermal conductivity, expected low tritium volubility, and expected low chemical reactivities with water and air. Some key concerns are the high activation and material compatibility issues. The initial assessment of this material, for fission applications, is presented in this paper.

    Full Text Available During a mire vegetation study, conducted mainly in the subalpine-alpine sector of the Western Italian Alps, the ecology of several plant communities and numerous moss species of this kind of vegetation was evaluated. The study area covered the Piedmontese sector of the Graian Alps, the eastern sector of the Aosta Valley as well as certain localities of the Pennine Alps, the Canavese district and the Maritime Alps. They have a rocky substratum representative of the various regional lithologies and include the main sectors characterised by the highest precipitation. Three hundred and twenty two relevées were made using the phytosociological method and the pH and the conductivity of the water table and its depth were measured directly. Cluster Analysis allowed a classification of the samples and the identification of various groups of plant communities. Ordination performed by DCA and CCA allowed us to identify the ecological features of the various plant communities by using the values of the main environmental parameters, measured directly in the field, and certain climatic parameters (altitude and mean annual precipitation available. The use of climatic parameters is an important result for identifying communities which show greater oceanicity, something that is underlined also by the presence of indicator species such as Sphagnum papillosum and S. subnitens. Furthermore the communities are arranged in a "poor-rich" gradient, and are also profoundly influenced by depth to water table which is inversely correlated to the pH. Therefore we find certain kinds of communities all with a very low water table and which are little affected by its chemistry. Other groups share the fact that the water table is outcropping or near the surface and are distinguishable for their pH values and conductivity. We discuss the different response of the bryophytes and vascular plants of these communities to the environmental parameters considered, in light of their

    Lymphadenopathy in children for which no infectious or malignant cause can be ascertained constitutes a challenging diagnostic dilemma. Autoimmune lymphoproliferative syndrome (ALPS) is a human genetic disorder of lymphocyte apoptosis resulting in an accumulation of lymphocytes and childhood onset chronic lymphadenopathy, splenomegaly, multilineage cytopenias, and an increased risk of B-cell lymphoma. In 1999, investigators at the National Institutes of Health (NIH) suggested criteria to establish the diagnosis of ALPS. Since then, with approximately 500 patients with ALPS studied worldwide, significant advances in our understanding of the disease have prompted the need for revisions to the existing diagnostic criteria and classification scheme. The rationale and recommendations outlined here stem from an international workshop held at NIH on September 21 and 22, 2009, attended by investigators from the United States, Europe, and Australia engaged in clinical and basic science research on ALPS and related disorders. It is hoped that harmonizing the diagnosis and classification of ALPS will foster collaborative research and better understanding of the pathogenesis of autoimmune cytopenias and B-cell lymphomas.

    1999-10-01

    We use two-dimensional numerical modeling techniques to investigate the thermomechanical consequences of closure of the Meliata-Hallstatt ocean and consequent Cretaceous continent-continent collision in the eastern Alps (Austria). In the modeling a lower plate position of the Austro-Alpine (AA) continental block is adopted during collision with the Upper Juvavic-Silice block. The thermal structure of the lithosphere was calculated for major AA tectonic units (Upper, Middle, and Lower Austro-Alpine) by integration of the transient heat flow equation along an approximately NW-SE cross section east of the Tauern Window. Indications of the rheological evolution of the AA were determined by calculating strength profiles at key stages of the Cretaceous orogeny, making use of the thermal modeling predictions combined with rock mechanics data. Cooling in the upper plate and lower greenschist facies metamorphism within footwall parts of the lower Upper Austro-Alpine (UA) plate, related to SE directed underthrusting of the UA beneath the Upper Juvavic-Silice block at circa 100 Ma, were predicted by the numerical model. The observed pressure-temperature path for deeply buried Middle Austro-Alpine (MA) upper crustal units and their subsequent isothermal exhumation are best reproduced assuming a pressure peak at 95 Ma and exhumation rates ranging between 4 and 7.5 mm yr-1. From the modeling results, we deduce that the temperature evolution during eclogite exhumation is primarily dependent on rates of tectonic movements and largely independent of the mode of exhumation (thrusting versus erosion). Furthermore, very rapid postmetamorphic exhumation of southern Lower Austro-Alpine (LA) units is predicted in order to account for subsequent cooling. This is constrained by 40Ar/39Ar data. The cooling paths of MA and LA rocks appear to be primarily controlled by their near-surface positions at the end of the Cretaceous rather than by other processes such as concurrent underthrusting

    Full Text Available Abstract Background The Austrian diabetes disease management program (DMP was introduced in 2007 in order to improve health care delivery for diabetics via the promotion of treatment according to guidelines. Considering the current low participation rates in the DMP and the question of further promotion of the program, it is of particular interest for health insurance providers in Austria to assess whether enrollment in the DMP leads to differences in the pattern of the provision of in- and outpatient services, as well as to the subsequent costs in order to determine overall program efficiency. Methods Historic cohort study comparing average annual levels of in- and outpatient health services utilization and its associated costs for patients enrolled and not enrolled in the DMP before (2006 and 2 years after (2009 the implementation of the program in Austria. Data on the use of services and data on costs were extracted from the records of the Austrian Social Insurance Institution for Business. 12,199 persons were identified as diabetes patients treated with anti-diabetic medication or anti-diabetics with insulin throughout the study period. 314 diabetics were enrolled in the DMP. Results Patients enrolled in the diabetes DMP received a more evolved pattern of outpatient care, featuring higher numbers of services provided by general practitioners and specialists (79 vs. 62, more diagnostic services (22 vs. 15 as well as more services provided by outpatient care centers (9 vs. 6 in line with increased levels of participation in medical assessments as recommended by the treatment guideline in 2009. Hospitalization was lower for DMP patients spending 3.75 days in hospital, as compared to 6.03 days for diabetes patients in regular treatment. Overall, increases in costs of care and medication throughout the study period were lower for enrolled patients (€ 718 vs. € 1.684, resulting in overall costs of € 5,393 p.c. for DMP patients and

    Full Text Available Within the last decades serious flooding events occurred in many parts of Europe and especially in 2005 the Austrian Federal Province of Tyrol was serious affected. These events in general and particularly the 2005 event have sensitised decision makers and the public. Beside discussions pertaining to protection goals and lessons learnt, the issue concerning potential consequences of extreme and severe flooding events has been raised. Additionally to the general interest of the public, decision makers of the insurance industry, public authorities, and responsible politicians are especially confronted with the question of possible consequences of extreme events. Answers thereof are necessary for the implementation of preventive appropriate risk management strategies. Thereby, property and liability losses reflect a large proportion of the direct tangible losses. These are of great interest for the insurance sector and can be understood as main indicators to interpret the severity of potential events. The natural scientific-technical risk analysis concept provides a predefined and structured framework to analyse the quantities of affected elements at risk, their corresponding damage potentials, and the potential losses. Generally, this risk concept framework follows the process steps hazard analysis, exposition analysis, and consequence analysis. Additionally to the conventional hazard analysis, the potential amount of endangered elements and their corresponding damage potentials were analysed and, thereupon, concrete losses were estimated. These took the specific vulnerability of the various individual elements at risk into consideration. The present flood risk analysis estimates firstly the general exposures of the risk indicators in the study area and secondly analyses the specific exposures and consequences of five extreme event scenarios. In order to precisely identify, localize, and characterize the relevant risk indicators of buildings

  1. Consideration of geomorphological uncertainties with terrestrial cosmogenic nuclide dating (TCND): combining Schmidt-hammer and 10Be dating, Southern Alps, New Zealand

    "by vision". Especially in regions like the Southern Alps affected of considerable neo-tectonic activity and paraglacial erosion, post-depositional movement of any boulders on moraine ridges cannot be excluded a priori. On base on these considerations, an attempt to combine TCND with Schmidt-hammer measurements for the dating of Holocene moraines and the reconstruction of a regional glacier chronology has been developed (Winkler 2009). Cosmogenic 10Be dating delivers ‘absolute' ages for the exposure of boulder surfaces, i.e. the same surface tested with the Schmidt-hammer relative-age dating technique. Therefore, Schmidt-hammer measurements can successfully endorse the selection of representative boulders for TCND and effectively avoid sampling boulders that have been exposed to post-depositional movement (e.g. rotation). Additionally, the number of boulders sampled for TCND can be reduced, positive in the light of economic and conservational considerations. Results from the application of this combined ‘multi-proxy-approach' at a number of individual glaciers in Westland/Tai Poutini and Mt Cook/Aoraki National Parks of the Southern Alps proof its potential. At least three ‘Little Ice Age'-type events culminating around 2,300, 1,600, and 1,000 years ago and predating the "Little Ice Age" have been confirmed. The construction of a dating curve based on both Schmidt-hammer and cosmogenic (10Be) dating results shows high significance and demonstrates the high potential of this attempt.

    Dwarf pines were discovered in 2004 during a paleoecological survey in the Mont Cenis massif (Savoy, France). These dwarf pines are the sole natural and spontaneous population in the NW French Alps of Pinus mugo Turra, ssp. mughus (Scop.) O. Schwarz. The population, fragile in light of the individual numbers, is currently isolated, but likely results from populations that would have covered larger areas during the Lateglacial or the early-Holocene, from the SW Alps (France) toward the Mont Cenis, throughout the Susa valley (Italy). With a fragmented distribution area of dwarf pine, the future of the Mont Cenis population seems altered due to important necroses observed on the topmost part of pine crowns, except for individuals that do not grow in the local ski station area. We stress the need for a conservation program to preserve this natural population, the sole known in the NW French Alps.

    The modification effect of a new type of Al-P master alloy on Al-24Si alloys was investigated. It is foundthat excellent modification effect can be obtained by the addition of this new type of A1-P master alloy into Al-24Simelt and the average primary Si grain size is decreased below 47 μm from original 225 μm. It is also found that theTiC particles in the melt coming from Al8Ti2C can improve the modification effect of the Al-P master alloy. Whenthe content of TiC particles in the Al-24Si melt is 0.03 %, the improvement reaches the maximum and keeps steadywith increasing content of TiC particles. Modification effect occurs at 50 min after the addition of the Al-P master al-loy and TiC particles, and keeps stable with prolonging holding time.

    Full Text Available A key to species belonging to the genus Diamesa Meigen, 1835 (Diptera, Chironomidae from the Alps and Apennines (Italy is presented using characters observable in the fourth-instar larva. The larvae are separated on the basis of qualitative and quantitative characters. At present fifteen species from the Italian Alps are described in all three life stages, but only twelve species groups can be separated as larvae. The separation is based on the length and thickness of anal setae, antennal ratio, head capsule color and few other characters of the labrum and mentum. The shape of mental and mandibular teeth is still a valid taxonomic character, but unfortunately these characters can be rarely used because teeth are often excessively worn in samples collected in the field. Quantitative characters show variability within each species, differing according to the duration of larval development and must be used with caution. The species groups which can be separated in the larval stage are: the dampfi group, which includes D. dampfi and D. permacra, the latitarsis group including D. modesta and D. latitarsis, the zernyi group including D. zernyi and D. vaillanti. The species within each of these groups at present cannot be separated. D. starmachi, D. steinboecki, D. goetghebueri, D. bertrami, D. aberrata, D. incallida, D. cinerella, D. tonsa and D. insignipes can be separated from all the other known species in larval stage.

    Conventional glacier-wide mass balances are commonly used to study the effect of climate forcing on glacier melt. Unfortunately, the glacier-wide mass balances are also influenced by the glacier's dynamic response. Investigations on the effects of climate forcing on glaciers can be largely improved by analyzing point mass balances. Using a statistical model, we have found that 52% of the year-to-year deviations in the point mass balances of six glaciers distributed across the entire European Alps can be attributed to a common variability. Point mass balance changes reveal remarkable regional consistencies reaching 80% for glaciers less than 10 km apart. Compared to the steady state conditions of the 1962-1982 period, the surface mass balance changes are -0.85 m water equivalent (w.e.) a-1 for 1983-2002 and -1.63 m w.e. a-1 for 2003-2013. This indicates a clear and regionally consistent acceleration of mass loss over recent decades over the entire European Alps.

The aim of this research was to shed light on the diatom richness in an Alpine context through i the collection of data concerning diatom communities inhabiting an unexplored watershed of the Maritime Alps Natural Park, including all of the most important aquatic habitats (comparison among river, springs and peat bogs and assemblages (epilithic and epiphytic diatom communities; ii analysis of the main environmental factors driving the development of diatom communities in different habitats. We completed a list of 174 diatom taxa. In general, river samples were poorer in terms of species richness than spring and peat bog ones, probably due to the selective role of the fast flow, while springs sheltered the highest biodiversity of the Valasco Valley. Peat bog communities were mainly composed of acidophilous taxa, sometimes planktonic and forming colonies. Epilithic and epiphytic samples did not show significant differences in terms of composition and biodiversity, even though it was statistically possible to identify indicator species for each assemblage. The study also highlighted the presence of several taxa included in the German Red List as endangered or decreasing, especially in the epiphytic samples. Since the water nutrient level and substrate geology were similar among habitats, the main environmental factors shaping Valasco diatom communities were water velocity and pH.

    A coevolutionary perspective is adopted to understand the dynamics of exposure to mountain hazards in the European Alps. A spatially explicit, object-based temporal assessment of elements at risk to mountain hazards (river floods, torrential floods, and debris flows) in Austria and Switzerland is presented for the period from 1919 to 2012. The assessment is based on two different data sets: (1) hazard information adhering to legally binding land use planning restrictions and (2) information on building types combined from different national-level spatial data. We discuss these transdisciplinary dynamics and focus on economic, social, and institutional interdependencies and interactions between human and physical systems. Exposure changes in response to multiple drivers, including population growth and land use conflicts. The results show that whereas some regional assets are associated with a strong increase in exposure to hazards, others are characterized by a below-average level of exposure. The spatiotemporal results indicate relatively stable hot spots in the European Alps. These results coincide with the topography of the countries and with the respective range of economic activities and political settings. Furthermore, the differences between management approaches as a result of multiple institutional settings are discussed. A coevolutionary framework widens the explanatory power of multiple drivers to changes in exposure and risk and supports a shift from structural, security-based policies toward an integrated, risk-based natural hazard management system.

    The reconstruction of triggering conditions, geomorphic effects, and damage produced by historical floods and debris flows significantly contributes to hazard assessment, allowing improved risk mitigation measures to be defined. Methods for the analysis of historical floods and debris flows vary greatly according to the type and quality of available data, which in turn are influenced by the time the events occurred. For floods and debris flows occurring in the Alps a few decades ago (between about 1950 and 1980), the documentation is usually better than for previous periods but, unlike events of most recent years, quantitative data are usually scanty and the description of the events does not aim to identify processes according to current terminology and classifications. The potential, and also the limitations of historical information available for the reconstruction of historical debris flows in the Alps have been explored by analyzing a high-magnitude debris flow that occurred on November 4, 1966 in the Chieppena Torrent (northeastern Italy). Reconstruction of the event was based on the use of written documentation, terrestrial and aerial photographs, and geomorphological maps. The analysis aimed to define the temporal development of phenomena, recognizing the type of flow processes and assessing some basic flow variables, such as volume, channel-debris yield rate, erosion depth, total distance traveled, and runout distance on the alluvial fan. The historical development of torrent hydraulic works, both before and after the debris flow of November 1966, was also analyzed with regard to the technical solutions adopted and their performance.

    In a letter to Miró Bonfill (Bishop of Girona) sent in march-april 984, Gerbert d'Aurillac wrote that "if you want to write something to us, please address your correspondence to Reims until the first of November or to Rome from December 25". This envisages a journey from Reims to Rome in the period 1th November - 25 December (Sigismondi, 2009). In those times the road normally used to reach Rome from Reims was the Via Francigena which crosses the Alps at the Great St Bernard pass. This pass is a privileged transit point through the Alps since ancient times as stated by the old name "Col de Mons Joux" that remembers the Jupiter's Pennino temple built along the old Roman road. The crossing point is at 2437 m asl, which from autumn to spring gives a significant risk of crossing failures due to snowfalls. The trip of Gerbert of Aurillac leads us to the general topic of the documentary sources of the crossings of the Alpine passes. The trust of Gerbert of Aurillac in the respect of the predefined travel time testifies a low perception of the risk of the transit of the Great St Bernard. This reinforces the evidence of an unusual mildness of Medieval period in Europe coming from many other documentary sources.

    Rock glaciers and protalus ramparts are characteristic landforms of the periglacial domain often used as markers for the occurrence of permafrost in mountain terrains. As such, relict rock glaciers can be used for paleoclimate reconstructions. We present here the first previously unreported rock glacier inventory of the south-eastern Alps (including the north-eastern-most region of Italy and Slovenia), interpreted from high resolution orthophotos and a high resolution digital terrain model interpolated from airborne laser scanning (LiDAR). We mapped 53 rock glaciers covering a total area of 3.45 km2. The majority of rock glaciers are classified as relict and distributed between 1708 and 1846 m a.s.l. with slope ranging between 19° and 27°. In addition to rock glaciers we observed 66 protalus (pronival) ramparts, having median elevation of 1913 m a.s.l. and covering 0.48 km2. More than half of the inventoried protalus ramparts are located in the more maritime area of the Alps with higher precipitation compared to the location of rock glaciers. Using paleoclimate reconstruction based on the 1981-2010 climatological record of the area, we infer that the rock glaciers formed during one of the dry and cold periods of the late Pleistocene and early Holocene. Possible evolution of the active pronival forms observed in the most maritime area of this alpine sector is also discussed.

  15. Atmospheric CO2 Consumption in Uplifting Mountain Ranges: New Insight From the New Zealand Southern Alps

    Rates of physical erosion and chemical weathering in uplifting mountain ranges are generally higher than the rates observed in tectonically stable regions. This observation has led to the hypothesis that orogenic events lead to global cooling over geologic time scales by accelerating the rate of atmospheric CO2 drawdown from silicate weathering. However, recent studies of rivers draining the rapidly uplifting Himalaya Mountains have demonstrated that much of the chemical weathering flux is dominated by carbonate dissolution, which does not influence long-term atmospheric CO2 levels. To examine if carbonate weathering dominates in other orogenic environments, we have undertaken investigations of rivers draining the New Zealand Southern Alps, which present a largely unexplored setting for systematically examining tectonic controls on the carbon cycle. In particular, we quantified rates of physical erosion and both silicate and carbonate weathering across a gradient of variable uplift rates but constant bedrock composition. We also compared the findings to global mean values as well as to data for major world rivers in other tectonic and climatic settings. Rapid uplift in the western Southern Alps elevates mechanical erosion rates by a factor of ~13 relative to those on the tectonically stable eastern side. Similarly, the average chemical weathering rate is ~5 times higher on the western compared to eastern side of the mountain range. However, because the proportion of stream-water Ca2+ and Mg2+ from the weathering of trace hydrothermal calcite increases as the rate of mechanical erosion increases, the long-term atmospheric CO2 consumption rate on the western side is only ~2 times higher than that on the eastern side and only ~1.5 times higher than the global mean value. These data demonstrate that tectonic uplift in the New Zealand Southern Alps accelerates physical erosion and chemical weathering rates but does not greatly enhance the rate of long-term atmospheric

  16. Subduction of European continental crust to 70 km depth imaged in the Western Alps

    The first conclusive evidence in support of the burial (and exhumation) of continental crust to depths larger than 90 km was provided by the discovery of coesite-bearing metamorphic rocks in the Dora Maira massif of the Western Alps (Chopin, 1984). Since then, even though similar outcrops of exhumed HP/UHP rocks have been recognized in a number of collisional belts, direct seismic evidences for subduction of continental crust in the mantle of the upper plate remain rare. In the Western Alps, the greatest depth ever recorded for the European Moho is 55 km by wide-angle seismic reflection (ECORS-CROP DSS Group, 1989). In an effort to image the European Moho at greater depth, and unravel the very complex lithospheric structure of the W-Alps, we have installed the CIFALPS temporary seismic array across the Southwestern Alps for 14 months (2012-2013). The almost linear array runs from the Rhône valley (France) to the Po plain (Italy) across the Dora Maira massif where exhumed HP/UHP metamorphic rocks of continental origin were first discovered. We used the receiver function processing technique that enhances P-to-S converted waves at velocity boundaries beneath the array. The receiver function records were migrated to depth using 4 different 1-D velocity models to account for the strongest structural changes along the profile. They were then stacked using the classical common-conversion point technique. Beneath the Southeast basin and the external zones, the obtained seismic section displays a clear converted phase on the European Moho, dipping gently to the ENE from ~35 km at the western end of the profile, to ~40 km beneath the Frontal Penninic thrust (FPT). The Moho dip then noticeably increases beneath the internal zones, while the amplitude of the converted phase weakens. The weak European Moho signal may be traced to 70-75 km depth beneath the eastern Dora Maira massif and the westernmost Po plain. At shallower level (20-40 km), we observe a set of strong

    Autoimmune lymphoproliferative syndrome (ALPS) is a disorder of lymphocyte apoptosis. Children present with chronic nonmalignant lymphadenopathy, hepatosplenomegaly, and autoimmune cytopenias. Recent advances show efficacy of treatment with immunosuppressive drugs. Sirolimus, an mammalian target of rapamycin inhibitor, improves autoimmune cytopenias and lymphoproliferation, with a safe profile. We present 2 patients, a 5-year-old girl and 15-year-old boy, diagnosed with ALPS with initial partial response to steroid treatment. Autoimmune cytopenias and lymphoproliferation then became refractory to treatment, with recurrence of symptoms. In both cases, treatment with sirolimus was started, with a rapid response, complete remission of cytopenias, and resolution of lymphoproliferation, with no significant adverse effects.

    School-related factors contributing to the suicidality of lesbian, gay, and bisexual individuals are understudied, especially in German-speaking Europe. Among our Web-based sample of 468 Austrian gay or bisexual adults, 18% attempted suicide and about one half of them reported that hard times at school related to one's homosexuality partly or mainly caused the attempt. Such suicide attempts were associated with a lack of acceptance at school and harassment experiences. In contrast to suicide attempts, acceptance at school was significantly associated with protective factors such as teachers intervening against homophobia or presence of openly homosexual teachers or peers. These findings may be important for consideration in school-based suicide prevention programs.

    Full Text Available Nowadays, creativity as it is applied for finding new technologies and making new inventions, is characterised by new unorthodox aspects of and approaches to problem solving. At the same time, innovation uses new scientific, technical and cultural elements to sustainably change the social structure of society. However, creative and innovative ideas are not affluent or ever-lasting resources. They need to be stimulated, elicited and put into realisation. This has to be done through expensive research and development cam-paigns, but may also be achieved at a lower level, namely, for example, at Austrian Technical Colleges. There, students are often encouraged to submit their diploma thesis projects in national and regional competitions and have recently proved to be very successful.

    In this set of presentation slides, after a review of worldwide energy resources the author presents his innovative technical solution aimed at contributing to future energy supply. An extra-flat solar concentrator was developed to produce industrial steam in the temperature range 150 to 300 {sup o}C. A prototype was operated on the site of the Federal Institute of Technology (EPFL) in Lausanne, Switzerland, for power generation at 12 kW{sub el}. In Ras al Khaimah, United Arab Emirates, the concept of the so-called Solar Island is to be tested. Construction work is underway. A floating circular platform will be equipped with parallel rows of extra-flat solar concentrators. The platform will rotate to follow the sun apparent movement and enhance the power output of the concentrators. A second project is presented that should be realised in the Swiss Alps. In this case the extra-flat concentrators will be mounted on existing steel constructions that prevent snow avalanches on steep grounds. The basic technical data of the two projects are given.

    Vibrio cholerae belonging to the non-O1, non-O139 serogroups are present in the coastal waters of Germany and in some German and Austrian lakes. These bacteria can cause gastroenteritis and extraintestinal infections, and are transmitted through contaminated food and water. However, non-O1, non-O139 V. cholerae infections are rare in Germany. We studied 18 strains from German and Austrian patients with diarrhea or local infections for their virulence-associated genotype and phenotype to assess their potential for infectivity in anticipation of possible climatic changes that could enhance the transmission of these pathogens. The strains were examined for the presence of genes encoding cholera toxin and toxin-coregulated pilus (TCP), as well as other virulence-associated factors or markers, including hemolysins, repeats-in-toxin (RTX) toxins, Vibrio seventh pandemic islands VSP-1 and VSP-2, and the type III secretion system (TTSS). Phenotypic assays for hemolysin activity, serum resistance, and biofilm formation were also performed. A dendrogram generated by incorporating the results of these analyses revealed genetic differences of the strains correlating with their clinical origin. Non-O1, non-O139 strains from diarrheal patients possessed the TTSS and/or the multifunctional autoprocessing repeats-in-toxin (MARTX) toxin, which were not found in the strains from ear or wound infections. Routine matrix-assisted laser desorption/ionization (MALDI-TOF) mass spectrometry (MS) analysis of all strains provided reliable identification of the species but failed to differentiate between strains or clusters. The results of this study indicate the need for continued surveillance of V. cholerae non-O1, non-O139 in Germany, in view of the predicted increase in the prevalence of Vibrio spp. due to the rise in surface water temperatures.

  4. A new Geo-Information Architecture for Risk Management in the Alps

    2009-04-01

    During the last decades land-use increased significantly in the Swiss (and European) mountain regions. Due to the scarceness of areas suitable for development, anthropic activities were extended into areas prone to natural hazards such as avalanches, debris flows and rockfalls (Smith 2001). Furthermore, the transalpine transport system necessity to develop effective links in an important area collides with the need to ensure the safety of travelers and the health of the population. Consequently, an increase in losses due to hazards can be observed. To mitigate these associated losses, both traditional protective measures and land-use planning policies are to be developed and implemented to optimize future investments. Efficient protection alternatives can be obtained considering the concept of integral risk management. Risk analysis, as the central part of risk management, has become gradually a generally accepted approach for the assessment of current and future scenarios (Loat & Zimmermann 2004). The procedure aims at risk reduction which can be reached by conventional mitigation on one hand and the implementation of land-use planning on the other hand: a combination of active and passive mitigation measures is applied to prevent damage to buildings, people and infrastructures. As part of the Swiss National Science Foundation Project 54 "Evaluation of the optimal resilience for vulnerable infrastructure networks - An interdisciplinary pilot study on the transalpine transportation corridors" we study the vulnerability of infrastructures due to natural hazards. The project aims to study various natural hazards (and later, even man-made) and to obtain an evaluation of the resilience according to an interdisciplinary approach, considering the possible damage by means of risk criteria and pointing out the feasibility of conceivable measures to reduce potential damage. The project consists of a geoscientific part and an application. The fist part consists in studying

    Foam stability is a key factor of beer quality for consumers and brewers. Recent beer proteome analyses have suggested that barley dimeric α-amylase inhibitor-1 (BDAI-1) and avenin-like protein-a (ALP) derived from barley are important for beer foam stability. In this study, BDAI-1 and ALP were purified from a Japanese commercial beer sample using salt precipitation and column chromatography. The purification level was verified using two-dimensional gel electrophoresis, mass spectrometry, and database searches. Purified BDAI-1 and ALP were added to a beer sample to compare the foam stability to that of a control beer sample. As a result, beer foam stability was significantly improved by BDAI-1 but not by ALP, thereby suggesting that BDAI-1 affects beer foam stability whereas ALP does not.

  7. Inventory of large landslides and rock avalanches in the European Alps

    Large deep-seated landslides include a broad range of instability phenomena (e.g. rockslide, rock slump, lateral spread, rock mass creep and sackung, rock avalanche) which in some cases can be found as combined or sequential processes, representing the progressive evolution of a complex slope instability. Complementing the orogen-scale inventory of DSGSD that has been recently presented for the European Alps (Crosta et al 2008, Agliardi et al 2012), we created an orogen scale inventory of large landslides (mainly rockslides) and rock avalanches. The inventory includes 1701 large landslides ranging in area between 0.1 and 17 km2, and 81 rock avalanches ranging between 0.09 and 15.5 km2. The inventory covers an area of about 110,000 km2 extending over the alpine territories of Italy, France, Switzerland, and Austria, and was prepared by using available satellite imagery (multi-temporal, Google Earth, Google, Inc.) and topographic data at different resolutions (DEMs from 1 m x 1m up to 20 m x 20 m for different areas). The inventory was validated against local or regional landslide inventories already available at different scales prepared by different subjects and using different means.. Geometrical features and geomorphological parameters have been collected and related to the different phenomena and local settings. The frequency-area relationship for the mapped features is presented. The inventory shows that large landslides are widespread in the Alps. Their spatial distribution has been analysed though bivariate and multivariate analysis (mainly Principal Component Analysis and Discriminant Analysis) against a variety of factors, including: lithology, proximity to tectonic structures, seismicity, uplift and exhumation rates, position within the mountain belt and along main and tributary valleys, slope morphometry (e.g. relief, elevation, gradient, etc.), ice thickness of glaciers during LGM, and mean annual rainfall. The analysis allowed a preliminary assessment

    Northern Apennines, Alps and surrounding regions are often studied separately. The structure of their upper mantle has been studied repeatedly in the past and some studies reported on the seismic anisotropic properties in the litho-asthenosphere. However, a joint interpretation of the Alps-Apennines transition zone is still lacking, mainly at depth. The China-Italy-France Alps seismic survey (CIFALPS, 2012) provided an improved image of the crust and upper mantle beneath the southwestern Alps and the transition to the Apennines. Here we show the SKS shear wave splitting results obtained from the analysis of teleseismic data recorded by 55 temporary seismic stations along the CIFALPS profile and by some other permanent stations. The strain-induced lattice preferred orientation of olivine minerals within the upper mantle, expressed by the analysis, confirms the NW trending fast polarization directions parallel to the strike of the orogen, in good agreement with the results of previous studies all along the Alpine chain. On the contrary, in the Po Plain, new shear wave splitting measurements show a scattered distribution; the coexistence of both NNE-SSW and E-W directions provides new insights on upper mantle deformation in the complex transition zone between the Alpine and Apenninic subductions. The comparison of this new dataset with recent tomographic studies and geological improvement should compose a more complete picture of the mantle structure and deformation of this puzzling region.

    2001-06-01

    Full Text Available The electromagnetic induction pattern in the Eastern Alps is characterised by a (continuous large-scale zone on which the real parts of the induction arrows show anomalous directional behaviour. This zone extends from the Penninic Domain of Eastern Switzerland (Graubünden probably into the Carpathian ranges. A coarse mesh of a Magnetotelluric (MT and Geomagnetic Deep Sounding (GDS station in the Alps of Graubünden and Valais (Western Switzerland indicates that this electromagnetic anomaly is restricted to the Mesozoic sediments of the North Penninic Bündnerschiefer-facies that begins in Eastern Switzerland and extends towards the east beneath Austroalpine, South Penninic and Southalpine units. Striking similarities in position and arrangement between this zone and the magnetic signature in the Eastern Alps are found. The analysis of the GDS data with the method of the Hypothetical Event Analysis (HEA shows that current channelling affects the electromagnetic fields in this zone and causes the anomalous direction of induction arrows. Based on the combined interpretation of GDS data from the Eastern Alps and West Hungary together with our recent data from Switzerland, the following geological implications are discussed: i a spatial decoupling of induction processes from the upper to the lower crust; ii a lower crustal conductive structure caused by the indentation of the Northern Adriatic promontory or terrane; iii the eastward continuation of the Bündnerschiefer-facies at least to the tectonic window of Rechnitz.

    Full Text Available The European Alps harbour a unique and species-rich biodiversity, which is increasingly impacted by habitat fragmentation through land-use changes, urbanization and expanding transport infrastructure. In this study, we identified the 50 most important questions relating to the maintenance and restoration of an ecological continuum - the connectedness of ecological processes across many scales including trophic relationship and disturbance processes and hydro-ecological flows in the European Alps. We initiated and implemented a trans-national priority setting exercise, inviting 48 institutions including researchers, conservation practitioners, NGOs, policymakers and administrators from the Alpine region. The exercise was composed of an initial call for pertinent questions, a first online evaluation of the received questions and a final discussion and selection process during a joint workshop. The participating institutions generated 484 initial questions, which were condensed to the 50 most important questions by 16 workshop participants. We suggest new approaches in tackling the issue of an ecological continuum in the Alps by analysing and classifying the characteristics of the resulting questions in a non-prioritized form as well as in a visual conceptualisation of the inter-dependencies among these questions. This priority setting exercise will support research and funding institutions in channelling their capacities and resources towards questions that need to be urgently addressed in order to facilitate significant progress in biodiversity conservation in the European Alps.

    Evaluating conflicting theories about the influence of mountains on carbon dioxide cycling and climate requires understanding weathering fluxes from tectonically uplifting landscapes. The lack of soil production and weathering rate measurements in Earth's most rapidly uplifting mountains has made it difficult to determine whether weathering rates increase or decline in response to rapid erosion. Beryllium-10 concentrations in soils from the western Southern Alps, New Zealand, demonstrate that soil is produced from bedrock more rapidly than previously recognized, at rates up to 2.5 millimeters per year. Weathering intensity data further indicate that soil chemical denudation rates increase proportionally with erosion rates. These high weathering rates support the view that mountains play a key role in global-scale chemical weathering and thus have potentially important implications for the global carbon cycle.

  17. Preliminary comparative study of middle Anisian vertebrate ichnoassociation from South-Eastern Alps

    2009-04-01

    Anisian vertebrate tracks from the south-eastern Alps are known since the first decades of 1900s (Abel, 1926). The sedimentary units yielding footprints are characterized by the alternation of limestone influenced by terrigenous supply with mere marine and volcanic layers allowing a precise dating. In this study, we compare four different ichnoassociations from three different outcrops in the South-Eastern Alps correlating them chronologically and sedimentologically. They were found to be subsequent in time from Lower Pelsonian (Bad Gfrill-Voltago Conglomerate; Todesco, 2007) through middle Pelsonian (Bad Gfrill- Giovo Formation) (Valdiserri et al., 2006) and basal Illyrian (Piz da Peres- Richthofen Conglomerate; Todesco et al., 2008) to the middle Illyrian (Val Duron-Morbiac Limestone; Avanzini et al., 2007). In all these ichno-associations, Rhynchosauroides, an ichno-genus referable to a lizard - like trackmaker well known in the European Anisian, is dominant. Within this group at least four different morphotypes are known, probably reflecting both intraspecific variation (i.e. sexual dimorphism) and different ichnospecies. Although the Chirotheridae group, referred to Archosaurian trackmakers Synaptichnium is represented in both Pelsonian ichnoassociation of the Bad Gfrill outcrop, while Chirotherium , Isochirotherium and Brachichirotherium are recognized both in Pelsonian and in Illyrian ichnosites with a incremental presence in the Illyrian The ichofamiliae Rotodactylidae und Procolophonidae seem well represented in the Pelsonian strata but absent in the Illyrian ones. The preliminarly comparative analysis of these four correlated ichnosites and the comparision with the yet known ones (Avanzini and Mietto 2008) pointed out the expected predominance of the Lepidosaurian-Archosaurian association typical for the middle Triassic ichnofauna. The incremental presence of the Chirotherian track in Illyrian and the presence of the Procolophonichium just in the

    The ALPS collaboration runs a light-shining-through-walls (LSW) experiment to search for photon oscillations into "weakly interacting sub-eV particles" (WISPs) inside of a superconducting HERA dipole magnet at the site of DESY. In this paper we report on the first successful integration of a large-scale optical cavity to boost the available power for WISP production in this type of experiments. The key elements are a frequency tunable narrow line-width continuous wave laser acting as the primary light source and an electronic feed-back control loop to stabilize the power build-up. We describe and characterize our apparatus and demonstrate the data analysis procedures on the basis of a brief exemplary run.

    Full Text Available Les Alpes, plus précisément les Alpes italiennes, plus que toute autre région d'Europe Occidentale, sont un lieu de grande diversité ethnoculturelle : pas moins de sept minorités linguistiques autochtones y coexistent, côte à côte avec la majorité officielle correspondante. Maintenant considérées comme un héritage culturel important par les états ainsi que par les régions, une nouvelle législation offre une protection à toutes les « minorités linguistiques historiques » en Italie. Notre étude montre, cependant, qu'il est très difficile de maintenir de tels groupes, car on ne sait pas vraiment où se situent exactement les zones de ces minorités. Partant de là, des groupes d'acteurs locaux, dans de nombreuses communautés, tirent partie de ce manque de connaissance et se déclarent territoires de minorité bien qu'ils ne présentent aucune variante linguistique. Un des objectifs importants de ce projet est, donc, d'établir une représentation cartographique de cette diversité linguistique. Ce document, par conséquent, traite d'études de cas de conscience ethnolinguistique distincte. Même si la Loi n° 482 a été un premier pas important pour la préservation des minorités linguistiques, leur déclin progressif, selon les critères territoriaux et numériques, ne peut pas être nié. Aujourd'hui, outre des facteurs biodémographiques défavorables et une « ethnicité diffuse », les processus démographiques en cours constituent d'autres causes. Dans ce cadre, les migrants d'agrément, ces nouveaux immigrants qui ont découvert les montagnes comme un nouvel espace d'installation recherché, jouent un rôle décisif en renforçant le processus d'assimilation.More than any other area in Western Europe, the Alps, especially the Italian Alps, are home to great ethno-cultural diversity: there, no less than seven autochthonous linguistic minorities coexist side by side with the respective official majority.
