The old afforestations of Austrian black pine dating from more than a century ago on marly substrates in the French Southern Alps play a protective role against erosion and torrential floods. However, these forests have now reached maturity and it is necessary to consider their renewal within the framework of minimal management to ensure sustainable protection against erosion. We first present methods for determining and mapping priority areas for forestry actions on different spatial scales,...
Full Text Available Multidisciplinary studies (genetic and phytocoenological of 4 populations of Austrian pine (Pinus nigra Arnold were carried out in western and central Serbia. The obtained results gave the same inter-population arrangement in both methods. Dendograms (NTSYS differentiate at the greatest genetic distance the population of Austrian pine in Šargan compared to other populations: Crni Vrh, Goč and Studenica. Using phytocoenological analysis it was determined that population of Austrian pine in Šargan forms a community Erico-Pinetum gocensis, while the other populations form a community Seslerio rigidae-Pinetum gocensis. Multidisciplinary approach that was demonstrated within this paper presents the first studies of Austrian pine that directly link genotype dependence and environmental conditions manifested through the phytocoenological affiliation.

Full Text Available This paper presents the results of soil research in Austrian pine (Pinus nigra Arn. forest communities in the Višegrad area, carried out to determine the basic soil characteristics and eco-production potential of forest habitats as an important basis and framework for the successful management of these forests on the principles of sustainable development. Austrian pine forests in this region are an important and ecologically valuable community. The complexity of the geological structure and relief dynamics are dominant environmental factors that condition the expressed variability of soils in the study area. Forest communities of Austrian pine are formed on the peridotites and serpentinites, eutric ranker (haplic leptosol, eutric cambisol (haplic cambisols and pseudogley (haplic planosol, dense granular and marl limestones calcomelanosol (mollic leptosol, rendzina (rendzic leptosol and calcocambisol (leptic cambisol. The productivity of these soils is highly correlated with depth and texture composition, and the impact of these factors is linked with soil type, climate and other site conditions. In the research area, soil types with low production potential such as rankers, rendzinas, limestone and dolomite calcomelanosol are dominant. Deeper variants of eutric cambisol, pseudogley and calcocambisol can be classified as soils with moderate to high production potential.

The alien woody legume, black locust (Robinia pseudoaca-cia), has invaded Japanese black pine (Pinus thunbergii) forests located in Japan’s coastal plain and hill regions where gaps are formed in pine forests after nematode infestation. Nitrogen fixation by legumes acceler-ates N cycling in forest ecosystems. We studied temporal change in the annual tree-ring resolution N stable isotope composition (δ15N, a per mil deviation of δ15N/14N ratio, relative to atmospheric N2δ15N=0‰) at two natural locations of Japanese black pine forest with black locust that differed in the time since black locust establishment (Shohnai in north-east and Kita-Kyushu in southwest Japan). Analyzed tree-rings covered the period from 1990/1992 to 2009. N acquisition by Japanese black pine from black locust N input to the soil was evidenced by temporal shifting of N stable isotope composition on the annual pine tree rings. With pro-gressive development of the forest stand,δ15N values of earlier tree-ringsδ15N of -5‰) from black pine associated with black locust shifted to-wards values similar to those of black locustδ15N values nearly to-1‰), which suggests acquisition of N by N2 fixation (Shohnai site). In con-trast, in a forest where black locust had settled for two or three genera-tions, in a black pine stand (Kita-Kyushu site), longer periods of N en-richment in the soil were reflected in the elevated tree-ringδ15N values of newly established black pine trees. Based on tree-ringδ15N data from the Shohnai site, we determined that about 10 years after black locust establishment, soil N had already been enriched by black locust N, this, in turn, contributed to N fertilization of surrounding trees in mixed stands.

In this paper, accurate tree stand height retrieval is demonstrated using C-band Shuttle Radar Topography Mission (SRTM) height and ancillary data. The tree height retrieval algorithm is based on modeling uniform tree stands with a single layer of randomly oriented vegetation particles. For such scattering media, the scattering phase center height, as measured by SRTM, is a function of tree height, incidence angle, and the extinction coefficient of the medium. The extinction coefficient for uniform tree stands is calculated as a function of tree height and density using allometric equations and a fractal tree model. The accuracy of the proposed algorithm is demonstrated using SRTM and TOPSAR data for 15 red pine and Austrian pine stands (TOPSAR is an airborne interferometric synthetic aperture radar). The algorithm yields root-mean-square (rms) errors of 2.5-3.6 m, which is a substantial improvement over the 6.8-8.3-m rms errors from the raw SRTM minus National Elevation Dataset Heights.
Full Text Available Determination of stem standing volume is very useful for both sustainable management of timber resources and practical purposes in forestry. Brutian pine (Pinus brutia Ten. and black pine (Pinus nigra Arnold. are important raw material of forest products industry of Turkey. With ever changing market conditions, there is a need to accurately estimate tree volumes utilizing multiple upper stem merchantability limits. This is not currently possible with the existing total stem volume tables for these three species. Nowadays, taper equations are the best way to estimate volume for saw timber and biomass purposes. In this study, variable exponent taper equations evaluated and fitted to data come from 253 destructively sampled trees which were collected in natural brutian pine and black pine stands in Eğirdir district. For this aim, the taper equations of Lee et al. (2003, Kozak (2004, and Sharma and Zhang (2004 were used. A second-order continuous-time autoregressive error structure was used to correct the inherent autocorrelation in the hierarchical data. The proposed models generally performed better for Merchantable tree volume. Results show that the Kozak (2004 taper equation was superior to the other equations in predicting diameter and merchantable height, while The Sharma and Zhang (2004 taper model provided the best predictions for merchantable volume than the other models. The one of the important results of this study, the importance of checking fit statistics of taper equations for both diameters and volume estimations.As a results, Sharma and Zhang (2004 taper model recommended for estimating diameter at a specific height, height to a specific diameter along the stem, and merchantable volume for brutian pine and black pine stands in Eğirdir analyzed

Conversion of the aging black pine plantations into ecologically more stable broadleaf forests is an important goal in many Mediterranean countries as well as in the sub-Mediterranean part of Slovenia. Six experimental plots, split between the more and the less productive site, were established near Divača in southwestern Slovenia in an area of mostly pure black pine stands. In November 2012 they were planted with six native broadleaf species (Celtis australis L., Quercus petraea (Mattuschka)...

The nitrogen-fixing tree black locust (Robinia pseudoacacia L.) seems to affect ectomycorrhizal (ECM) colonization and disease severity of Japanese black pine (Pinus thunbergii Parl.) seedlings. We examined the effect of black locust on the distribution of ECM and pathogenic fungi in soil. DNA was extracted from soil at depths of 0-5 and 5-10 cm, collected from the border between a Japanese black pine- and a black locust-dominated forest, and the distribution of these fungi was investigated by denaturing gradient gel electrophoresis. The effect of soil nutrition and pH on fungal distribution was also examined. Tomentella sp. 1 and Tomentella sp. 2 were not detected from some subplots in the Japanese black pine-dominated forest. Ectomycorrhizas formed by Tomentella spp. were dominant in black locust-dominated subplots and very little in the Japanese black pine-dominated forest. Therefore, the distribution may be influenced by the distribution of inoculum potential, although we could not detect significant relationships between the distribution of Tomentella spp. on pine seedlings and in soils. The other ECM fungi were detected in soils in subplots where the ECM fungi was not detected on pine seedlings, and there was no significant correlation between the distribution of the ECM fungi on pine seedlings and in soils. Therefore, inoculum potential seemed to not always influence the ECM community on roots. The distribution of Lactarius quieticolor and Tomentella sp. 2 in soil at a depth of 0-5 cm positively correlated with soil phosphate (soil P) and that of Tomentella sp. 2 also positively correlated with soil nitrogen (soil N). These results suggest the possibility that the distribution of inoculum potential of the ECM fungi was affected by soil N and soil P. Although the mortality of the pine seedlings was higher in the black locust-dominated area than in the Japanese black pine-dominated area, a pathogenic fungus of pine seedlings, Cylindrocladium pacificum, was
Full Text Available The selection of tree species can affect the success of afforestation in the rehabilitation of degraded forest sites and forest restoration. In general, black locust (Robinia pseudoacacia L. and black pine (Pinus nigra Arnold. represent the most commonly used species in the afforestation of soils that have been degraded by erosion. As far as the extent of the ameliorative effects of black locust and black pine are concerned, it was found that they may play an important role in the selection of species for the afforestation of extremely degraded sites. This study is aimed at determining the potential of black locust and black pine to affect several soil properties, erosion control and C stock, thus creating favourable site conditions for the restoration of previous forest vegetation. This research was conducted in the Grdelica Gorge in south east Serbia, where eight sample plots with an average size of 0.47 ha were established 60 years ago on terrain afforested with black locust and black pine. In each sample plot, we measured the diameter at breast height of all black locust and black pine trees, and the height of 10 black locust and 10 black pine trees in each diameter class. In addition, samples of mineral soil (from depths of 0-5, 5-10 and 10-20 cm were taken at 4 randomly selected soil profiles in each sample plot, and 8 samples of litter (30 × 30 cm were also collected. Additionally, laboratory analyses of the physical and chemical properties of the soil and litter were performed in 2 replicates. The obtained results showed that: (1 at the 0-5 cm depth, there was no statistically significant difference in the reaction of the soil solution, although a significant difference in the reaction of the soil solution between the soils under the two species was observed at soil depths greater than 5 cm; (2 there was a significantly higher N content under black locust in the 0-5 cm soil layer; (3 the reduction of soil loss under black locust is

The decay of forest cover and soil erosion is a consequence of continual intensive forest exploitation, such as grazing and wildfires over the centuries. From the end of the eighteenth century up to the mid-1900s, black pine plantations were established throughout the Apennines' range in Italy, to improve forest soil quality. The main aim of this reafforestation was to re-establish the pine as a first cover, pioneer species. A series of thinning activities were therefore planned by foresters when these plantations were designed. The project Selpibiolife (LIFE13 BIO/IT/000282) has the main objective to demonstrate the potential of an innovative silvicultural treatment to enhance soil biodiversity under black pine stands. The monitoring will be carried out by comparing selective and traditional thinning methods (selecting trees from below leaving well-spaced, highest-quality trees) to areas without any silvicultural treatments (e.g. weeding, cleaning, liberation cutting). The monitoring survey was carried out in Pratomagno and Amiata Val D'Orcia areas on the Appennines (Italy) and involved different biotic levels: microorganisms, mesofauna, nematodes and macrofauna (Coleoptera). The results displayed a significant difference between the overall biodiversity of the two areas. In particular, microbial diversity assessed by both biochemical (microbial biomass, microbial respiration, metabolic quotient) and molecular (PCR-DGGE) approaches highlighted different a composition and activity of microbial communities within the two areas before thinning. Furthermore, little but significant differences were observed for mesofauna and nematode community as well which displayed a higher diversity level in Amiata areas compared to Pratomagno. In contrast, Coleoptera showed higher richness values in Pratomagno, where the wood degrader Nebria tibialis specie dominated, compared to Amiata. As expected, a general degraded biodiversity was observed in both areas before thinning.
Full Text Available The authors deal with the problem of the re-naturalization of afforestations of Black pine in the Apennines (Central Italy. Gap-cutting of two different sizes (the gap diameter/stand height ratios were respectively 0.75 and 1.0 on age classes stands (respectively 50 and 90 years old have been carried out. The results of the dynamics of the tree regeneration established in the gaps 7 years after the beginning of the experiment are given. The Black pine represents the best regenerated tree species and its presence is increasing. Some broadleaves, Pubescent oak (Quercus pubescens Willd. and Holm oak (Quercus ilex L. particularly, and Hop-hornbeam (Ostrya carpinifolia Scop. and Manna-ash (Fraxinus ornus L. on a subordinate way, are also present in the gaps. These results confirm that the gap-cutting system represents an effective instrument for the natural regeneration priming and a low impact environmental treatment which is particularly fit for the re-naturalization of the conifers’ monocultures. According to this experience the gaps’ optimal sizes are 150-250 m2. These gaps should be distributed appropriately in space and time.
Full Text Available Black pine plantations have been established at the purpose of recovering a forest cover to marginal soils, mostly throughout the Apennines range in Italy, since the end of the eighteenth century and up to the mid 1900. Both the decay of forest cover and soil erosion were the outcome of the long-lasting overuse through the intensive forest exploitation practices, grazing of the forest floor and wildfires, occurring since many centuries ago. The primary function of pine reafforestation was therefore to re-establish a first cover with a pioneer species, preparatory to future mixed forest types based on the natural reintroduction of broadleaves originally living in the same areas, mainly deciduous oaks and beech in the upper part. These goals have been partly met over the wide reafforestation area; the key functions of pine stands are today the protection against soil erosion and the hydrological regulation of catchments. The pine stands have been assuming today also a scenic role because they have been incorporated in the landscape physiognomy. A series of thinning up to the regeneration phase had been planned by foresters since the design of these plantations, but many stands have grown unthinned and fully stocked for a long time, this condition contributing a less mechanical stability of trees. Alternative forms of regeneration in grown-up stands have been and are being tested to improve both the natural and artificial establishment of indigenous species, but thinnings remain, even if a tardy measure, the main practice enforceable to these pine forests. The results of experimental trials undertaken in the black pine forest stand located in Pratomagno casentinese (Arezzo are being reported in the paper. The study started in 1978 and the following theses were tested (A heavy thinning from below; (B moderate thinning from below; (C control. Three thinnings were carried out in 1978, 1999 and 2009 at the ages of 24, 45 and 55. The action over time of

As a result of the Ecological (climate, soil, air pollution and Biological (insect, fungus, parasite plant etc. researches; other factors the exception of drought have no priority affection on black pine deaths. As on Turkey, drought conditions have dominated on the region after the year 1994. These changes have been occurred by constantly deaths in community of black pines on the south-facing slope (between the years 2000-2009. Increasing temperature and evaporation, decreasing relative humidity and rainfall-runoff is clearly for the region. In addition, there were not air pollution and infected primer insect-fungus damage. This also strengthens the impact of drought. Identified areas of tree deaths in recent years are generally near the inner regions (the steppe areas. Climate change and drought must be an indication of pushing towards more humid areas of black pine forests which is able to approaching much more onto the steppes of inner Anatolian.

Tree barks are relevant interfaces between plants and the external environment, and can effectively retain airborne particles and elements at their surface. In this paper we have studied the distribution of mercury (Hg) in soils and in black pine (Pinus nigra) barks from the Mt. Amiata Hg district in southern Tuscany (Italy), where past Hg mining and present-day geothermal power plants affect local atmospheric Hg concentration, posing serious environmental concerns. Barks collected in heavily Hg-polluted areas of the district display the highest Hg concentration ever reported in literature (8.6mg/kg). In comparison, barks of the same species collected in local reference areas and near geothermal power plants show much lower (range 19-803μg/kg) concentrations; even lower concentrations are observed at a "blank" site near the city of Florence (5-98μg/kg). Results show a general decrease of Hg concentration from bark surface inwards, in accordance with a deposition of airborne Hg, with minor contribution from systemic uptake from soils. Preliminary results indicate that bark Hg concentrations are comparable with values reported for lichens in the same areas, suggesting that tree barks may represent an additional useful tool for biomonitoring of airborne Hg.

Wildfire and mountain pine beetle infestations are naturally occurring disturbances in western North American forests. Black-backed woodpeckers (Picoides arcticus) are emblematic of the role these disturbances play in creating wildlife habitat, since they are strongly associated with recently-killed forests. However, management practices aimed at reducing the economic impact of natural disturbances can result in habitat loss for this species. Although black-backed woodpeckers occupy habitats created by wildfire, prescribed fire, and mountain pine beetle infestations, the relative value of these habitats remains unknown. We studied habitat-specific adult and juvenile survival probabilities and reproductive rates between April 2008 and August 2012 in the Black Hills, South Dakota. We estimated habitat-specific adult and juvenile survival probability with Bayesian multi-state models and habitat-specific reproductive success with Bayesian nest survival models. We calculated asymptotic population growth rates from estimated demographic rates with matrix projection models. Adult and juvenile survival and nest success were highest in habitat created by summer wildfire, intermediate in MPB infestations, and lowest in habitat created by fall prescribed fire. Mean posterior distributions of population growth rates indicated growing populations in habitat created by summer wildfire and declining populations in fall prescribed fire and mountain pine beetle infestations. Our finding that population growth rates were positive only in habitat created by summer wildfire underscores the need to maintain early post-wildfire habitat across the landscape. The lower growth rates in fall prescribed fire and MPB infestations may be attributed to differences in predator communities and food resources relative to summer wildfire. PMID:24736502

Biomass burning produces black carbon (BC), effectively transferring a fraction of the biomass C from an actively cycling pool to a passive C pool, which may be stored in the soil. Yet the timescales and mechanisms for incorporation of BC into the soil profile are not well understood. The High Park fire (HPF), which occurred in northwestern Colorado in the summer of 2012, provided an opportunity to study the effects of both fire severity and geomorphology on properties of carbon (C), nitrogen (N) and BC in the Cache La Poudre River drainage. We sampled montane ponderosa pine forest floor (litter plus O-horizon) and soils at 0-5 and 5-15 cm depth 4 months post-fire in order to examine the effects of slope and burn severity on %C, C stocks, %N and BC. We used the benzene polycarboxylic acid (BPCA) method for quantifying BC. With regard to slope, we found that steeper slopes had higher C : N than shallow slopes but that there was no difference in BPCA-C content or stocks. BC content was greatest in the forest floor at burned sites (19 g BPCA-C kg-1 C), while BC stocks were greatest in the 5-15 cm subsurface soils (23 g BPCA-C m-2). At the time of sampling, unburned and burned soils had equivalent BC content, indicating none of the BC deposited on the land surface post-fire had been incorporated into either the 0-5 or 5-15 cm soil layers. The ratio of B6CA : total BPCAs, an index of the degree of aromatic C condensation, suggested that BC in the 5-15 cm soil layer may have been formed at higher temperatures or experienced selective degradation relative to the forest floor and 0-5 cm soils. Total BC soil stocks were relatively low compared to other fire-prone grassland and boreal forest systems, indicating most of the BC produced in this system is likely lost, either through erosion events, degradation or translocation to deeper soils. Future work examining mechanisms for BC losses from forest soils will be required for understanding the role BC plays in the global
Full Text Available The main aim was to develop models for predicting diameter at breast height (DBH, merchantable tree volume (V, and aboveground biomass (AGB of individual black pine (Pinus nigra Arn. trees grown in Sub-Mediterranean Croatian pure even-aged forests, which will be suitable for remote sensing based forest inventories. In total, eight variables obtained from field measurement, existing database, and digital terrain model were candidates for independent variables in regression analysis. DBH, V, and AGB were modeled as linear function of each of the independent variables, and all possible linear combinations thereof. Goodness of fit of every model was then evaluated using R2 statistic. Comparison between selected models showed that the variability of all dependent variables are explained best by models which include both crown diameter and tree height as independent variables with coefficients of determination of 0.83, 0.89, 0.82 for DBH, V, and AGB, respectively. Consequently, these models may be recommended as the most suited for DBH, V and AGB estimation of black pine trees grown in pure Sub-Mediterranean forest stands using high-resolution aerial images or high-density airborne laser scanning data. This assumption should be further validated by conducting remote sensing inventory and comparing the obtained results with field measurement results.

Full Text Available In this study, the effects of different soil preparation treatments on regeneration of black pine success were examined and some suggestions were given according to the results. Twelve sample plots were randomly set in the research area. The size of each sample plot was 4 m². Sample plots were seeded equally with a total number of 2304 (48 seeds per m2 seeds in April 2012. The number of surviving seedlings was recorded every month from May to November in 2012. Surviving seedlings were recorded again in November 2013 and growths of thirty seedlings which are selected randomly from the all sample plots were examined. It was found that soil treatment with machine was more successful in regeneration at semi-arid regions like Cerkes-Turkey. Plowing equipment as mechanical soil cultivation has more economically advantageous in first years. However, the success and quality of seedlings were better in soil preparation with ripper equipment compared to plowing.

The Austrian school of economics is an unorthodox approach to economics whose adherents have mostly been libertarian in their political outlook. This dissertation explores the connections between Austrian economic theory and libertarian political philosophy, and casts doubt on the claim often propounded that Austrian economics itself naturally leads to libertarianism. Instead it is claimed here that Austrian economics is an open-ended theory that can lead to very different political conclusio...
This study was performed to determine modeling height growth of Anatolian black pine (Pinusnigra Arn. ssp. pallasiana (Lamb.) Holmboe) stands according to the site factors in the Buldan forest district. Site index and environmental data obtained from 19 sample plots in the district were fitted by Stepwise Multiple Regression Analysis (SMRA) and Regression Tree (RT) using SPSS 17.0 and DTREG softwares. Schist structured quartzites, slope position and clay percent of B horizon (R2 =0,67) were determined as the most significant variables for the model obtained from SMRA. Two different models were determined by RT statistics. The first one was represented by slope position and altitude (R2 =0,67), while slope position and surface stoniness were the most important variables in the second model and prediction values of site index were separately calculated by all these models. Consequently, R2 =0,84 was the most significance level when the average of these prediction values correlated with the actual site index values. (author)
In the 2011 Franz Cuhel Memorial Lecture, I argue that the study of endogenous rule formation in economic life (what I term the positive political economy of anarchism) should be studied in-depth and that the economic analysis of the Austrian school of economics provides many of the key analytical insights necessary for such study.

 In boreal forests, fire is a frequent disturbance and converts soil organic carbon (OC) to more degradation-resistant aromatic carbon, i.e., black carbon (BC) which might act as a long-term atmospheric-carbon sink. Little is known on the effects of fires on boreal soil OC stocks and molecular composition. We studied how a surface fire affected the composition of the forest floor of Siberian Scots pine forests by comparing the bulk elemental composition, molecular structure (13C-MAS NMR), ...
With the completion of the Austrian Radon Project, the map of the annual mean radon concentrations in Austrian homes is available now. The extrapolation of the indoor data to a standard situation was used to create a 'radon potential' map, which should indicate the radon risk from the ground without the influence of house type, living situation and all other parameters, that could influence the indoor radon concentration. This map specifies areas where radon-safe building techniques should be applied. In the next future the main task for the Austrian radon program will be the transformation of recommendations into use, i. e. to inform the public as well as to teach the persons who are responsible for the construction of a house, how to make a house radon-safe. It seems essential that all people who are involved in the construction of a house, starting from the planning and ending with the people working at the building site, should be informed about the problems with radon because a lack of knowledge in one part of the chain could substantially reduce the effectiveness of any protective measure. The way we try to inform the public as well as several special target groups will be demonstrated. An important question is the effectiveness of such information campaigns. This means: does the information reach the target groups, are the people accepting this information and finally do they apply the recommendations? Therefore it seems necessary to test the methods of information distribution for their efficiency already during the information campaigns. (orig.)
This text was written by E. Broda for the international symposium for exploration of the Austrian exile from 1934 to 1945 (“Internationales Symposiums zur Erforschung des österreichischen Exils von 1934 bis 1945”) in the year 1978. The article is about the specific problems of the Austrian scientific landscape, caused by the political events in the first half of the 20th century. The focus is primarily on the enormous ‘brain drain’, triggered by political repression in the period of Nazi rule (1938 - 1945), the Austro-fascism period (1934 - 1938) and the economic regression, anti-intellectual and anti-Semitic sentiment in the Country since 1918. The article emphasizes the importance of exile organizations, such as the ‘Free Austrian Movement’ or the ‘Association of Austrian Engineers, Chemists and Scientific Workers in Great Britain’ for the reconstruction of a scientific culture in Austria, after the Second World War.

In the year 2014, the Austrian National Network( network code OE ), operated by the Austrian Seismological Service at the Zentralanstalt für Meteorologie und Geodynamik, consists of 21 strong-motion sites (FBA-23 and Episensor, triggered data acquisition) and 16 broadband stations (STS-2 or STS-2.5, continuous data acquisition). Among the 16 broadband stations there are 14 sites collocated with accelerometers (FAB-23 or Episensor). The Research Group Geophysics at the Vienna University of Technology and the Department of Meteorology and Geophysics at the University of Vienna are operating temporary seismic stations, data from these instruments is integrated in the processing at the Austrian Seismic Network. Data from instruments in neighboring countries is also integrated in the processing. The Austrian Seismological Service collects and evaluates felt reports. A major upgrade of both hard- and software used for processing (Antelope 5.4, Intel based hardware) is planned for the year 2015. Some new tools for data processing processing and evaluation are presented. An overview of the seismic monitoring at the Austrian Seismological Service will be presented for the year 2014. We compare automatic processing and manual evaluation results. Performance of the automated data processing (rate of valid, false and missed events), statistics and information about significant earthquakes and earthquake sequences in Austria will be presented.
Full text: The LHC at CERN in Geneva plans to resume operation and start data acquisition in fall 2009. The High Energy Physics Group at the Austrian Academy of Science and the Astro- and Particle Physics Group at the University of Innsbruck are part of the CMS and the ATLAS experiments. Both experiments have a high demand on computing power and data storage. To allow Austrian scientists to analyze the produced data in 2008 the Austrian Ministry of Science signed the Computing Memorandum of Understanding (C-MoU) which defines the Worldwide LHC computing collaboration and its objectives. To conform to this C-MoU the two institutes installed a federated tier-2 computing center. (author)
This environmental baseline survey (EBS) report documents the baseline environmental conditions of five land parcels located near the U.S. Department of Energy's (DOE's) East Tennessee Technology Park (ETTP), including West Black Oak Ridge, East Black Oak Ridge, McKinney Ridge, West Pine Ridge, and Parcel 21d. Preparation of this report included the detailed search of federal government records, title documents, aerial photos that may reflect prior uses, and visual inspections of the property and adjacent properties. Interviews with current employees involved in, or familiar with, operations on the real property were also conducted to identify any areas on the property where hazardous substances and petroleum products, or their derivatives, and acutely hazardous wastes may have been released or disposed. In addition, a search was made of reasonably obtainable federal, state, and local government records of each adjacent facility where there has been a release of any hazardous substance or any petroleum product or their derivatives, including aviation fuel and motor oil, and which is likely to cause or contribute to a release of any hazardous substance or any petroleum product or its derivatives, including aviation fuel or motor oil, on the real property.

This environmental baseline survey (EBS) report documents the baseline environmental conditions of five land parcels located near the U.S. Department of Energy?s (DOE?s) East Tennessee Technology Park (ETTP), including West Black Oak Ridge, East Black Oak Ridge, McKinney Ridge, West Pine Ridge, and Parcel 21d. Preparation of this report included the detailed search of federal government records, title documents, aerial photos that may reflect prior uses, and visual inspections of the property and adjacent properties. Interviews with current employees involved in, or familiar with, operations on the real property were also conducted to identify any areas on the property where hazardous substances and petroleum products, or their derivatives, and acutely hazardous wastes may have been released or disposed. In addition, a search was made of reasonably obtainable federal, state, and local government records of each adjacent facility where there has been a release of any hazardous substance or any petroleum product or their derivatives, including aviation fuel and motor oil, and which is likely to cause or contribute to a release of any hazardous substance or any petroleum product or its derivatives, including aviation fuel or motor oil, on the real property.

This research was conducted to investigate the suitability of peanut hull to produce general purpose particleboards. A series of panels were produced using peanut hull and mixture of peanut hull and European Black pine wood chips. Particleboards were manufactured using various hull ratios in the mixture (0%, 25%, 50%, 75% and 100%). Urea formaldehyde adhesive was utilized in board production and boards were produced to target panel's density of 0.7 g/cm3. Panels were tested for some physical (water absorption and thickness swelling), chemical (holocellulose content, lignin content, alcohol-benzene solubility, 1% NaOH solubility, hot water solubility and cold water solubility) and mechanical (modulus of rupture, modulus of elasticity and internal bond) properties. The main observation was that increase in peanut hull in the mixture resulted in a decrease in mechanical and physical properties of produced panels and panel including 25% hull in the mixture solely met the standard required by TS-EN 312 standard. Conclusively, a valuable renewable natural resource, peanut hull could be utilized in panel production while it has been mixed to the wood chips. PMID:17689074

The spread of invasive tree species in forests can be slow because of their long life span and the lag phases that may occur during the invasion process. Models of forest succession are a useful tool to explore how these invasive species might affect long-term forest development. We used the spatially explicit individual tree model SORTIE-ND to gain insight into the long-term development of a gap-dependent invasive tree species, Prunus serotina, in a pine-oak forest on sandy soil, the forest type in which P. serotina occurs most often in its introduced range. Forest inventory data, tree ring data, and photographs of the tree crowns were collected in a forest reserve in the Netherlands, characterized by high game densities. The collected data were then combined with data from literature to parameterize the model. We ran the model for two different scenarios in order to evaluate the impact of differences in the regeneration success of the native Quercus robur and the invasive P. serotina. The outcome of the simulations shows two differing courses of forest development. The invasive P. serotina became the dominant species when the regeneration of Q. robur was hindered, e.g., because of high herbivore densities. When both Q. robur and P. serotina were able to regenerate, Q. robur became the most abundant species in the long-term. We hypothesize that the relatively short life span of P. serotina may preclude its dominance if other long-lived tree species are present and able to regenerate.

This paper reviews the key elements of Austrian macroeconomics and aims to find out whether the Austrian business cycle theory can explain causes to Norwegian business cycles between 1979 and 2009. The Austrian school suggests that monetary interventions disturb the term structure of interest rates. This causes the capital structure to change which accounts for fluctuations of the business cycle. Credit- induced expansions with unchanged time-preferences create unsustaina...

This study aims to investigate the effects that stand age and forest structure generates on soil respiration and litterfall quantity. The effect of stand age on these variables was studied in a shelterwood system Spanish Black pine chronosequence in central Iberian Peninsula composed of 0-20, 20-40, 40-60, 60-80, 80-100-year-old. For each stand age, six forest stands with similar characteristics of soil type and site preparation were used. Also, a forest area ranging 80-120 years old and without forest intervention was selected and used as control. We also measured organic matter, C:N ratio, soil moisture and pH in the top 10 mineral soil at each compartment. Soil respiration measurements were carried out in three time points (3, 8 and 12 days). Results showed a clear trend in soil respiration, comparing all the experimental areas. Soil respiration showed the same trend in all stands. It initially showed higher rates, reaching stability in the middle of the measurement process and finally lightly increasing the respiration rate. The older stands had significantly higher soil respiration than the younger stands. Soil organic matter values were also higher in the more mature stands. C:N ratio showed the opposite trend, showing lower values in the less mature stands. More mature stands clearly showed more quantity of litterfall than the younger ones and there was a positive correlation between soil respiration and litterfall. Finally, the multivariate PCA analysis clearly clustered three differenced groups: Control plot; from 100 to 40 years old and from 39 to 1 years old, taking into account both soil respiration and litterfall quantity, also separately. Our results suggest that the control plot has a better soil quality and that extreme forest stand ages (100-80 and 19-1 years old) and the associated forest structure generates differences in soil respiration.
ENVIRONMENTAL BASELINE SURVEY REPORT FOR WEST BLACK OAK RIDGE, EAST BLACK OAK RIDGE, MCKINNEY RIDGE, WEST PINE RIDGE, AND PARCEL 21D IN THE VICINITY OF THE EAST TENNESSEE TECHNOLOGY PARK, OAK RIDGE, TENNESSEE

This environmental baseline survey (EBS) report documents the baseline environmental conditions of five land parcels located near the U.S. Department of Energy’s (DOE’s) East Tennessee Technology Park (ETTP), including West Black Oak Ridge, East Black Oak Ridge, McKinney Ridge, West Pine Ridge, and Parcel 21d. The goal is to obtain all media no-further-investigation (NFI) determinations for the subject parcels considering existing soils. To augment the existing soils-only NFI determinations, samples of groundwater, surface water, soil, and sediment were collected to support all media NFI decisions. The only updates presented here are those that were made after the original issuance of the NFI documents. In the subject parcel where the soils NFI determination was not completed for approval (Parcel 21d), the full process has been performed to address the soils as well. Preparation of this report included the detailed search of federal government records, title documents, aerial photos that may reflect prior uses, and visual inspections of the property and adjacent properties. Interviews with current employees involved in, or familiar with, operations on the real property were also conducted to identify any areas on the property where hazardous substances and petroleum products, or their derivatives, and acutely hazardous wastes may have been released or disposed. In addition, a search was made of reasonably obtainable federal, state, and local government records of each adjacent facility where there has been a release of any hazardous substance or any petroleum product or their derivatives, including aviation fuel and motor oil, and which is likely to cause or contribute to a release of any hazardous substance or any petroleum product or its derivatives, including aviation fuel or motor oil, on the real property. A radiological survey and soil/sediment sampling was conducted to assess baseline conditions of Parcel 21d that were not addressed by the soils-only NFI

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.

"Whether and, if so, in what sense Joseph A. Schumpeter (1883-1950) and Ludwig von Mises (1881-1973) may both be classified as ‘Austrian economists’ is a controversial issue. In terms of their biographical background they were, of course, Austrian nationals, and as students of Böhm-Bawerk and von Wieser both qualify in a formal sense as third-generation members of the Austrian School. Yet, whether they so qualify in a substantive sense as well is much more questionable. Apparen...
For the first time, Austrian emissions of anthropogenic particulate matter emissions to the atmosphere have been estimated. Results have been reported as total suspended particles (TSP) as well as for the fractions of particles smaller than 10 μm or 2.5 μm aerodynamic diameter (PM10, PM2.5), respectively. Base years for the inventory were 1990, 1995 and 1999. Excluded from this assessment is wind blown dust, which has been considered a natural source here. National statistics have been applied, specifically those also used previously in the Austrian air pollution inventory (OLI). Emission factors have been taken from literature compilations, only for exceptional cases specific Austrian assessments were performed or original literature on emission measurements was consulted. Resuspension of dust by road traffic emerged as the most important source. For the size fraction of PM10 this source contributed about half of the emissions, when applying the calculation scheme by the U.S. EPA. While this scheme is widely used and well documented, its validity is currently subject of intense scientific debate. As these results do not seem to coincide with ambient air measurements, resuspension of road dust is considered separately and not now included in the national total. The sum of all other sources increases from 75,000 t of TSP in 1990 and 1995 to 77,000 t in 1999, while both PM10 and PM2.5 exhibit decreasing tendency (at 45,000 t and 26,000 t in 1999, respectively). The increase in TSP derives from increasing traffic and friction related emissions (tire wear, break wear), decrease of the finer particulate matter is due to reductions in firewood consumption for domestic heating. Most important source sectors are fugitive emissions from material transfer in industry as well as the building industry and the tilling of agricultural land. Common to these sources is the high uncertainty of available data. Wood combustion is the most important of the non-fugitive emissions

Full Text Available The genetic-ecological variation of Scots pine (Pinus sylvestris L. in Serbia was studied in the populations at five localities in western and south-western Serbia. Three groups of Scots pine (Pinus sylvestris L. populations were differentiated based on genetic research (seed protein analysis and plant community research. The first group consists of Scots pine populations on Šargan (FMU “Šargan“ and on Tara (FMU “Kaluderske Bare”, where the forests belong to the community of Scots pine and Austrian pine (Pinetum sylvestris-nigrae Pavlovic 1951. The second group covers the localities Stolovi (FMU “Radocelo-Crepuljnik“ and Zlatar (FMU “Zlatar I“, where the forests belong to the community of Scots pine and spruce (Piceo abietis-Pinetum sylvestris Stefanovic 1960. The third group comprises the Scots pine population on Pešter (FMU “Dubocica-Bare“ which belongs to the community of Scots pine with erica (Erico-Pinetum sylvestris Stefanovic 1963. Cluster analysis was performed on the basis of seed protein data and showed that there are three groups of Scots pine populations. The three populations coincide with plant communities. The community of Scots pine with erica (Erico-Pinetum sylvestris Stefanovic 1963 recorded on Pešter at the locality “Dubocica- Bare“ in the area of FE “Golija“ Ivanjica, is a special Scots pine population displayed at the greatest distance from all other populations in the cluster analysis dendrogram.

The Austrian forest industry consumed about 14.5 million m3/u.b. industrial roundwood in 1980 to compare with a total domestic cutting of 13 million m3/u.b. The dominating primary manufacturer is the sawmilling industry which in 1980 consumed about 70% of the total industrial wood consumption. About 65% of the sawnwood production is exported. In this paper, four scenarios are presented for the Austrian saw mills. These scenarios show that future problems such as (i) overcapacity; (ii) in...

This paper presented the results of tests conducted to determine if the addition of waste fatty acids from vegetable oil processing might decrease tall oil soap solubility in pine-beetle impacted wood from British Columbia (BC). The soap recovery and tall oil production at BC mills has fallen by 30 to 40 percent in recent years due to the pulping of high proportions of grey-stage beetle-impacted wood. Full-scale mill tests were conducted over a 4-day period. The study showed that the addition of tall oil fatty acids or waste fatty acids from vegetable oil processing could decrease tall oil soap solubility and increase the soup skimming efficiency in mills pulping a large percentage of grey stage beetle-infested wood. The addition of fatty acids increased tall oil soap skimming efficiency from 50.2 percent in the baseline tests to 71.8 percent based on the total soap available, and from 76.7 percent in the baseline tests to 87.5 percent based on insoluble soap only. The economic analyses indicated that waste fatty acid addition could be economical when natural gas and oil prices are high. 4 tabs., 9 figs.

We previously reported a high level of information on the Austrian organ donation law in medical and non-medical students, patients and ICU nurses, whereby ICU nurses at University Hospital in Graz (n = 185) were very well informed and also had the most critical view of the Austrian organ donation law.This letter reports the extension of our previous study to ICU nurses from hospitals with a Christian background (n = 60). We found that ICU nurses in hospitals run by religious congregations considered the Austrian organ donation law to be good more often than did those at the University Hospital in Graz. A positive attitude was also influenced by gender and prior knowledge of the law.Reasons for this could be the Christian orientation of the hospitals or exposure to organ donation and transplantation procedures on the job.

Effects of thinning intensities in experimental plots of Black European pine in “Foreste Casentinesi, Monte Falterona and Campigna National Park” (Tosco-Romagnolo Apennine, Italy, eight years after the felling
Full Text Available Different thinning intensities were compared in a 50-years-old plantation of Pinus nigra sp. located in the “Foreste Casentinesi Monte Falterona e Campigna” National Park (northern Apennine - Italy. Six experimental square plots (900 m2 were set up for comparison of two thinning intensities: heavy thinning (F: approximately 30% of basal area removed, light thinning (d: approximately 15% of basal area removed and control (Co. The comparison concerned: (1 the periodic increment of the trees in terms of volume (Ipv, average dbh (Ipd, height (Iph and the variation of height/diameter ratio (S in time; (2 forest canopy cover, indirectly expressed in term of relative irradiance (I.R.. Eight years after the felling, the results highlight that F thinning: (a increases the homogeneity of timber, as the stand volume is concentrated in dominant trees; (b favours tree diameter increment: Ipd values increase significantly according to the thinning intensity; (c reduces tree height increment (lower values of Iph were recorded in the F plots; (d promotes stand stability: lower value of S are highlighted in F plots, and no significant increase of this parameter in time has been recorded. As regards canopy cover, a significant negative correlation was recorded between stand basal area after the thinning and I.R. at ground level. After harvesting, a significant difference in terms of average I.R. between thinning intensities (F, d and Co was also recorded: nowadays, significant differences of average I.R. are observed between Co and d, whereas F shows intermediate values: the canopy gap originated from the felling has been quickly filled. Our results highlight the growth potential of Black European pine in the studied area; however, only heavy thinning shows interesting results in terms of both tree growth and stand stability.

Full Text Available Capital is strongly related to growth and development. Unfortunately, nowadays not many are those who actually understand the meaning underneath these connections. Our main concern becomes providing strong proof for the idea according to which a misallocation of capital betrays disastrous consequences, both from a pure economical as well as from an ecological perspective. Thus, the purpose of our paper finds its roots in revealing the answer to the question whether society requires a new economico-ecological mentality oriented towards a sane and efficient resource allocation along the productive process. The response we found is that it desperately does so. Formulating the argument benefits from the Austrian School precepts as it bifurcates into separate paths to follow along the paper. The first one highlights our main assumption according to which Austrian economics are, from a certain perspective, ecological oriented as their capital theory is thoroughly linked to an environmental friendly growth. The second trail entails the development of a plan under the form of possible solutions for escaping the recurrence of imbalances. A considerable part is also allocated to pointing out the main indicators that emphasize the guiding alarm signals: prices and private property.
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 Federal Research and Testing Institute Arsenal (BFPZ Arsenal) and the Austrian Federal Environmental Agency (UBA) cooperate in the frame of a research contract concerning the monitoring of the tritium concentrations of precipitation in Austria. Monthly mixed samples of 20 stations have been analysed in the year 1993. Compared to 1992 the tritium concentration in precipitation has increased about 10%. The stations N-77 (Bregenz) and N-64 (Patscherkofel) show slightly higher values compared to the other stations. The concentrations at Patscherkofel N-64 (2,245 m above sea-level), which have been significant higher in comparison with the other stations since about the end of the seventies (the cause for this special behaviour is not known until now), have been further decreasing in comparison to 1992.

The Federal Research and Testing Institute Arsenal (BFPZ Arsenal) and the Austrian Federal Environment Agency (UBA) cooperate in the frame of a research contract concerning the monitoring of the tritium concentrations of precipitation in Austria. Monthly mixed samples of 20 stations have been analysed in the year 1994. Compared to 1993 the tritium concentration in precipitation did not change very substancially. The measured concentrations are far below critical values concerning health. The stations N-77 (Bregenz) and N-64 (Patscherkofel) show slightly higher values compared to the other stations. The concentrations at Patscherkofel N-64 (2,245 m above sea-level), which have been significant higher in comparison with the other stations since the early eighties (the cause for this special behaviour is not known until now), have been further decreasing in comparison to 1993. Possible causes are discussed for the raised 3H-content of precipitation at the Patscherkofel near Innsbruck. (author)

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.

Austrian Carbon Calculator (ACC) - modelling soil carbon dynamics in Austrian soils. The project funded by the Klima- und Energiefonds, Austrian Climate Research Programme, 4th call Authors: Katrin Sedy, Alexandra Freudenschuss, Gerhard Zethner (Environment Agency Austria), Heide Spiegel (Austrian Agency for Health and Food Safety), Uwe Franko, Ralf Gründling (Helmholtz Centre for Environmental Research) Climate change will affect plant productivity due to weather extremes. However, adverse effects could be diminished and satisfying production levels may be maintained with proper soil conditions. To sustain and optimize the potential of agricultural land for plant productivity it will be necessary to focus on preserving and increasing soil organic carbon (SOC). Carbon sequestration in agricultural soils is strongly influenced by management practice. The present management is affected by management practices that tend to speed up carbon loss. Crop rotation, soil cultivation and the management of crop residues are very important measures to influence carbon dynamics and soil fertility. For the future it will be crucial to focus on practical measures to optimize SOC and to improve soil structure. To predict SOC turnover the existing humus balance model the application of the "Carbon Candy Balance" was verified by results from Austrian long term field experiments and field data of selected farms. Thus the main aim of the project is to generate a carbon balancing tool box that can be applied in different agricultural production regions to assess humus dynamics due to agricultural management practices. The toolbox will allow the selection of specific regional input parameters for calculating the C-balance at field level. However farmers or other interested user can also apply their own field data to receive the result of C-dynamics under certain management practises within the next 100 years. At regional level the impact of predefined changes in agricultural management

Our contribution aims at revealing the terms of a confrontation between Austrian and Institutional schools concerning the nature and the role of markets. Such an approach is justified by, on the one hand, the characteristics shared by both theoretical traditions, and on the other by the existence of complementarity, which founds a representation of market mechanisms in terms of process. The point is that if the economic analysis of institutions constitutes an essential link in the Austrian pr...
Objectives of the Austrian radon mitigation research project were to find cost-effective methods for characterizing the radon situation of dwellings and to evaluate the implementation of remedial actions for Austrian house types. Three houses in regions with elevated radon levels were closely examined. The methods used for radon diagnosis and the mitigation concept are described. The conception and implementation of proposed remedial actions are highlighted. Preliminary results of the investigations and remedial actions are presented. (A.K.)

The Czech Republic and Slovakia belong to the small and increasingly concentrated group of countries in Central, Eastern and Southeastern Europe (CESEE) whose banking markets have continued to generate substantial profits for Austrian banks also after the outbreak of the financial crisis in 2008. This short study sheds light on why Austrian subsidiaries have been able to maintain their profitability in these two countries especially when compared to those in other CESEE countries. We find tha...

(*)University of Applied Sciences Wiener Neustadt, Austria (+)FOTEC GmbH, Wiener Neustadt, Austria (+) Spaceteam, TU Wien, Austria (~) University Wien, Wien, Austria The QB50 project is an international project with the goal to send up to 50 Nanosatellites, a.k.a. CubeSat, into the Thermosphere. The scientific goal of this mission is to monitor over a period of up to nine months the prevailing conditions in this rather unknown part of Earth's atmosphere. Each of the 50 nanosatellites will be equipped with one of three possible scientific instruments: (i) a set of Langmuir probes, (ii) atomic oxygen measurement device, (iii) ion/neutral mass spectrometer. All satellites will be launched together and released in a string-of-pearls type fashion. It is predicted that the satellites will drift apart rather rapidly following the release. Therefore, the QB50 missions offers the possibility of a measurement grid in the thermosphere of unprecedented scope and accuracy. One of the satellites, named PEGASUS, is designed and build by a team of Austrian researches and students. PEGASUS will be equipped with the aforementioned Langmuir probes and will provide information about essential properties of the plasma in the thermosphere such as the electrontemperature and -density. In order to ensure the capability to collect and downlink the data over several months, PEGASUS requires about the same types of subsystems as one would find on large-scale satellites. This includes an attitude control system, an on-board computer, telecommunication devices, an electrical power systems allowing to harvest the solar power and either distribute or store it for later use, a thermal control system

The question this research tries to answer is if an artificial credit expansion caused the Icelandic economy to go into an Austrian style business cycle in the first decade of this century. To answer that question data from the Statistic of Iceland and the Central Bank of Iceland will be studied. The period that will be looked at is the years from 2001 until 2010. The framework that is used is taken from Jesús Huerta de Soto´s book “Money, Bank Credit, and Economic Cycles”, in that book d...

We investigated the responses of collembolan communities to pine afforestation in an area formerly characterized by a mosaic of autochthonous downy oak woodland and steppe meadows. Study sites were selected in mixed stands of black pine and Scots pine and control samples were taken from downy oak stands and open steppe meadows. A total of 1884 Collembola specimens belonging to 66 species were collected. Three species, namely Protaphorura pannonica (Onychiuridae), Tomocerus mixtus (Tomoceridae...

We present clinical, pathological and molecular features of the first Austrian family with fatal familial insomnia. Detailed clinical data are available in five patients and autopsy in four patients. Age at onset of disease ranged between 20 and 60 years, and disease duration between 8 and 20 months. Severe loss of weight was an early symptom in all five patients. Four patients developed insomnia and/or autonomic dysfunction, and all five patients developed motor abnormalities. Analysis of the prion protein (PrP) gene revealed the codon 178 point mutation and methionine homozygosity at position 129. In all brains, neuropathology showed widespread cortical astrogliosis, widespread brainstem nuclei and tract degeneration, and olivary 'pseudohypertrophy' with vacuolated neurons, in addition to neuropathological features described previously, such as thalamic and olivary degeneration. Western blotting of one brain and immunocytochemistry in four brains revealed quantitative and regional dissociation between PrP(res)(the protease resistant form of PrP) deposition and histopathology. In the cerebellar cortex of one patient, PrP(res) deposits were prominent in the molecular layer and displayed a peculiar patchy and strip-like pattern with perpendicular orientation to the surface. In another patient, a single vacuolated neuron in the inferior olivary nuclei contained prominent intravacuolar granular PrP(res) deposits, resembling changes of brainstem neurons in bovine spongiform encephalopathy.

Since 2003 the Austrian Stroke-Unit-Registry has been administered by the Gesundheit Osterreich GmbH. A total of 26 out of the 32 existing Stroke Units in Austria take part in the project, financed by the Federal Ministry of Health and accompanied by a steering group. This paper provides a description of the objectives, organisation, methodology and the data set of the registry. The main objective of the registry is quality assurance and quality improvement of stroke-treatment in stroke units. Therefore, the participating stroke units document their cases using a web-based database. The data are discussed in the steering group and the stroke units get feedback in terms of benchmarking-graphs. The data set follows a modular approach and contains information about stroke, transport, admission to the hospital, stroke unit discharge and the 3-month follow-up. Between 2003 and 2007 about 27,000 cases (containing about 20,000 strokes) were documented in the registry. PMID:18766309

Full Text Available The aim of the project was to find out whether environmental sustainability can be measured not only with regard to climate change and carbon consumption but also as to other criteria concerning material consumption, energy, soil, biodiversity and water. We investigated which measures in the vineyard and wine cellar can lead to “better” sustainability while ensuring a high quality standard. 343 activities were identified to fulfill 61 quality objectives. Of the 2,191 sustainability assessments that were determined the measurements of the individual sustainability criteria vary and are in some cases even negatively correlated. Nevertheless, it was still possible to differentiate sustainably managed wineries from others in all of the Austrian wine producing areas. In our approach, a specifically developed online tool can calculate the expression of ecological, economic and social sustainability and show the effects in a spider diagram in the form of a traffic light rating system. Moreover, an algorithm suggests adequately which quality improvements can be achieved. If part of the management system is changed the online tool will show the positive and negative sustainability effects.
All commercially available mineral waters of Austrian origin were investigated with regard to the natural radionuclides 228Ra, 226Ra, 210Pb, 210Po, 238U and 234U. From 1 to 1.5 L of sample the nuclides were extracted and measured sequentially: the radium isotopes as well as 210Pb were measured by liquid scintillation counting after separation on a membrane loaded with element-selective particles (Empore Radium Disks), 210Po was determined by α-particle spectroscopy after spontaneous deposition onto a copper planchette and uranium was determined also by α-particle spectroscopy after anion separation and microprecipitation with NdF3. The calculated committed effective doses for adults, teens and babies were compared to the total indicative dose of 0.1 mSv/year given in the EC Drinking Water Directive. The dominant portion of the committed effective dose was due to 228Ra. Highly mineralised waters showed also higher 226Ra and 228Ra levels. (author)

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.

According to the draft of the new European Basic Safety Standards (EU-BSS) all member states are obliged to develop a national radon action plan, to control the long term risks from radon exposure in dwellings, public buildings and workplaces. The National Radon Centre, embedded in the Austrian Agency for Health and Food Safety (AGES), was assigned by the Ministry for Environment (BMLFUW) to develop this Austrian action plan and the strategy behind. This conference contribution discusses where we still have a need for actions and how the new BSS will influence the Austrian radon legislation (reference levels, responsibilities, standards, building law). Currently running and planned projects regarding the radon action plan like developing a national radon data base, definition of radon prone areas by improving the radon map and strategies to increase public radon awareness and involve the building sector are presented.

In this thesis the Austrian business cycle theory is analyzed. Based on the work of Eugen von Böhm-Bawerk (1959), Knut Wicksell (1962) and Ludwig von Mises (1953), 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...
Full text: The European patient protection directive (97/43 EURATOM) requires regular routine quality control (QC) of PET imaging devices. Since no standards were available covering this area and in order to comply with the directive a joint working party of the Austrian societies of nuclear medicine and of medical physics have developed a set of procedures suitable for both dedicated PET scanners and gamma cameras operating in coincidence mode (GCPET). The routine procedures proposed include both manufacturer recommended procedures and tests for specific parameters and calibration procedures. Wherever possible, procedures adapted or derived from NEMA standards publication NU 2-2001 were used to permit direct comparison with specified parameters of image quality. For dedicated PET scanners the most important procedures are the checking of detector sensitivities and the attenuation calibration scan. With full ring scanners the attenuation calibration scan is a blank scan, with partial ring devices a special attenuation calibration phantom has to be used. Test protocols are specific to manufacturer and scanner type. They are usually performed automatically overnight. In addition, some instruments require special calibrations, e.g. gain adjustments or coincidence timing calibration. GCPET procedures include the frequent assessment in coincidence mode of detector uniformity, energy resolution and system sensitivity. Common to both dedicated PET and GCPET are the regular quarterly assessment of tomographic spatial resolution and the calibration of the system for quantitative measurements. As a total performance test for both systems assessment of image quality following NU 2-2001 was included, to be carried out after major system changes or repairs. The suite of QC procedures was tested on several dedicated PET and GCPET systems including all major manufacturers' systems. Due to missing hardware or software not all tests could be performed on all systems. Some of the

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.
Full Text Available There is growing evidence suggesting that the United States’ roots are not in a state of “pristine” nature but rather in a “human-modified landscape” over which Native people have since long exerted vast control and use. The longleaf pine is a typical woodland use largely shaped by fires, lightning and by Native Americans. The frequent fires, which were used to reduce fuels and protect themselves from wildfires, enhance wildlife habitats and for hunting, protect themselves from predators and enemy tribes, led to the establishment of the fire dependent and fire tolerant longleaf pine across the southern landscape. In the last 3 centuries however, the range of longleaf ecosystem has been gradually replaced first by agriculture and then by loblolly pine farming. The joint effects of agricultural expansion, intense logging of the longleaf in the late 1800s, expanded fire control since the early 20th century, and subsequent bare-root planting beginning in the 1930s, has permitted loblolly pine to become dominantly established in the south. Longleaf and loblolly pines represent two distinct woodland uses and represent separate human values. This study investigated the change from longleaf pine use to loblolly pine farming in Southern US from perspectives of human values of land and natural resources.
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

To date, research on household wealth has seldom focused on households’ business equity holdings. Such equity stakes represent above all ownership in domestic limited liability companies. This study for the first time provides an empirical analysis of the distribution of Austrian households’ equity stakes in limited liability companies. For our analysis, we draw on data from three sources: the Company Register, a commercial database and the OeNB’s 2004 Survey on Financial Household Wealth. In...
In this paper I argue that the unequal distribution of knowledge implies that an Austrian theory of the firm must investigate two items. The first is the growth of knowledge within the firm (learning process), the second the way in the rights to decide over the distribution of knowledge are assigned and controlled. Finally, because those two elements are interdependent, we must define what their possible relations can be.

The methodological individualism and subjectivism of the Austrian tradition in economics is often associated with a methodological dualism, i.e. the claim that the nature of its subject matter, namely purposeful and intentional human action, requires economics to adopt a methodology that is fundamentally different from the causal explanatory approach of the natural sciences. This paper critically examines this claim and advocates an alternative, explicitly naturalistic and empiricist outlook ...

Full text: The EU has declared that all foodstuff must be able to be traced back from 'fork to farm' to increase the safety of food and the confidence of the consumers in food quality and safety. Additionally, several incidents of 'food diseases and scandals' related with meat (e.g.: BSE, foot and mouth disease, antibiotics abuse, avian flu, etc.) have demonstrated the necessity to trace back the origin of meat, to be able to locate sources of infection/mismanagement. Besides the conventional method of the control of documentation there is the possibility of control of origin by analysing the isotopic composition of meat and herewith controlling the questioned good itself. Stable isotope ratios of the elements HCNOS are varying geographically due to different environmental conditions (e.g.: climate, geology, soil, altitude, geography, etc.) thus every region possesses an individual pattern. The isotopic pattern is imprinted on plants and animals growing in a certain region, and therefore analysis of the stable isotope pattern can allow the identification of agricultural goods from different regions. For the control of origin of Austrian meat about 500 beef and 500 pork samples have been collected from slaughterhouses and were analysed for the isotopic composition of carbon, nitrogen, oxygen and sulphur and compared with the isotopic composition of meat samples from neighbouring countries. As Austria, despite being a small country, is very heterogeneous in its environmental conditions, thus there are significant differences in the isotopic patterns of individual Austrian provinces. The isotopic signature of meat samples from neighbouring countries can overlap with the 'Austrian isotope pattern' due to similar environmental conditions. However, a correct statistical classification has been achieved for 80% and 84% of the analysed beef and pork samples, respectively. If the declared origin of meat can be pinned down to an Austrian province, the discrimination power of
Full Text Available In this lecture delivered November 2008 on the occasion of the presentation of the Mises Institute’s Gary G. Schlarbaum Prize for lifetime achievement in the cause of liberty, Professor Salin discusses his discovery of Austrian economics and his involvement in “the world of individual liberty,” and draws various lessons from his intellectual journey. The coherence of Austrian economics appealed to Salin—it is not a patchwork of partial theories, but a logical process of thought founded on realistic assumptions about individual action. Salin also discusses differences between the Chicago and Austrian approaches, and his views about monetary systems.The financial crisis beginning in late 2008 is not a crisis of capitalism, but of state intervention, caused by the expansionary monetary policy of the Fed. Capitalism is the solution, not the cause. There is no need to create money. There is never any balance of payments problem. What is required is tax systems more friendly to capital accumulation, a decrease in the role of the state, the end of monetary policy and, if possible, the disappearing of central banks and the IMF.

Common critique of the Austrian business cycle theory states that the Austrian cycle could not be initiated under the rational expectations hypothesis. This thesis therefore investigates the role of price expectations of entrepreneurs in the Austrian cycle theory. We conclude that this theory might be compatible with rational expectations only under several assumptions. The rational expectations hypothesis is, however, evaluated rather critically concluding it is quite strong and unrealistic ...
The present work deals with the existence of State aid in the Austrian electricity industry and focuses on three selected areas of the Austrian legal system, which are examined for their compatibility with Community law. Subject of the first part of this work is a representation of the article 87 ff Treaty of Rome and its impact on Austrian provisions on the promotion of electricity from renewable energies or on the promotion of cogeneration energy. In this context, the first principles of the European state aid law and in particular the European Court are presented regarding the existence of State aid. Here, the Rsp of the Court in connection with the use of State resources in the Rs PreussenElektra Stardust Marine and Pearle is paid in connection with para-fiscal levies special attention. The evaluation of the Austrian support model is based on PreussenElektra, Stardust Marine and Pearle. Then the system of green electricity production in Austria represented. In addition to the Community law principles (green power directive, frameworks and guidelines for environmental aid) is here in particular the 'Oekostromgesetz' and treated it's novellas. It is an intensive discussion with the Commission's decisions on the compatibility of the green power and CHP funding and the funding of the countries with state aid rules. As part of this analysis is to attempt a classification of the Commission's practice in the Community legal system. The second part of the work deals with the determination of absorbed. System utilization rates and their distribution to the network operator. After a presentation of the Community legislation (EC regulations, the internal electricity market directives) and Rsp of the European Court of Justice (Case ADBHu, Ferring, Altmark Trans) to services of general economic interest is first attempted to determine the presence of these services in the 216 Austrian legislation. Here, the question will be, entrusted with services of general economic

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.

Much of this work is original research by the authors. However, published literature on the mountain pine beetle is reviewed with particular reference to epidemic infestations in lodgepole pine forests. The mountain pine beetle and lodgepole pine have evolved into an intensive and highly compatible relationship. Consequently, stand dynamics of lodgepole pine is a primary factor in the development of beetle epidemics. the diameter-growth relationship and the effects of environmental factors on...
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.

The Austrian chronic myeloid leukemia (CML) registry monitors individual disease courses, treatments applied, clinical outcome, and side effects of CML patients on a nationwide basis to provide data on the "real-life" situation and to complement the information and interpretation gained from the selected patient population observed in clinical trials. This report summarizes the Austrian CML registry data as of March 2009. A total of 179 patients have been registered with a median number of 1012 follow-up visits and median observation duration of 20 months. At diagnosis most patients (n = 163) were in chronic phase (early, late, and secondary), whereas only 4 were in advanced phase. A total of 137 patients were treated with tyrosine kinase inhibitors (TKIs), of which 14 received first and second generation TKIs sequentially. Other treatment modalities included chemotherapy or interferon and stem cell transplantation (SCT). Cumulative incidence rates for complete hematological responses (CHR) were 91.6% and 94.4% at 12 and 24 months, respectively, compared to cumulative incidence rates of complete cytogenetical response rates of 64% and 80% at these timepoints. A total of 5 patients progressed from chronic phase to accelerated (n = 3) and blastic phase (n = 2) while receiving imatinib standard dose. Estimated overall survival (OS) rate at 60 months was 90% and progression free survival (PFS) according to European Leukemia Net (ELN) failure definition was 58%. PMID:20936366
The Austrian Dosimetry Laboratory, established and operated in cooperation between the Austrian Research Center Seibersdorf and the Federal Office of Metrology and Surveying (Bundesamt and Eich- und Vermessungswesen) maintains the national primary standards for radiation dosimetry. Furthermore its tasks include routine calibration of dosemeters and dosimetric research. The irradiation facilities of the laboratory comprise three X-ray machines covering the voltage range from 5 kV to 420 kV constant potential, a 60Co teletherapy unit, a circular exposure system for routine batch calibration of personnel dosemeters with four gamma ray sources (60Co and 137Cs) and a reference source system with six gamma ray sources (60Co and 137Cs). In addition a set of calibrated beta ray sources are provided (147Pm, 204Tl and 90Sr). The dosimetric equipment consists of three free-air parallelplate ionization chambers serving as primary standards of exposure for the X-ray energy region, graphite cavity chambers with measured volume as primary standards for the gamma radiation of 137Cs and 60Co as well as different secondary standard ionization chambers covering the dose rate range from the natural background level up to the level of modern therapy accelerators. In addition for high energy photon and electron radiation a graphite calorimeter is provided as primary standard of absorbed dose. The principle experimental set-ups for the practical use of the standards are presented and the procedures for the calibration of the different types of dosemeters are described. (Author)

As a result of the Ecological (climate, soil, air pollution and Biological (insect, fungus, parasite plant etc. researches; other factors the exception of drought have no priority affection on black pine deaths. As on Turkey, drought conditions have dominated on the region after the year 1994. These changes have been occurred by constantly deaths in community of black pines on the south-facing slope (between the years 2000-2009. Increasing temperature and evaporation, decreasing relative humidity and rainfall-runoff is clearly for the region. In addition, there were not air pollution and infected primer insect-fungus damage. This also strengthens the impact of drought.Identified areas of tree deaths in recent years are generally near the inner regions (the steppe areas. Climate change and drought must be an indication of pushing towards more humid areas of black pine forests which is able to approaching much more onto the steppes of inner Anatolian.ÖzetBu çalışmada, Kahramanmaraş ili Göksun-Afşin ilçeleri arasında kalan Tülüce tepe mevkisindeki Anadolu karaçamı [Pinus nigra Arn. subsp. pallasiana (Lamb.

The growth of a pine tree is examined by preparing "tree cookies" (cross-sectional disks) between whorls of branches. The use of Christmas trees allows the tree cookies to be obtained with inexpensive, commonly available tools. Students use the tree cookies to investigate the annual growth of the tree and how it corresponds to the number of whorls…
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
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.
The ''1993 Energy Report'' and the ''1993 Energy Concept'' were drawn up by the Federal Minister of Economics and published by the Austrian government.

Mechanical biological treatment (MBT) of municipal solid waste (MSW) has become an important technology in waste management during the last decade. The paper compiles investigations of mechanical biological processes in Austrian MBT plants. Samples from all plants representing different stages of degradation were included in this study. The range of the relevant parameters characterizing the materials and their behavior, e.g. total organic carbon, total nitrogen, respiration activity and gas generation sum, was determined. The evolution of total carbon and nitrogen containing compounds was compared and related to process operation. The respiration activity decreases in most of the plants by about 90% of the initial values whereas the ammonium release is still ongoing at the end of the biological treatment. If the biogenic waste fraction is not separated, it favors humification in MBT materials that is not observed to such extent in MSW. The amount of organic carbon is about 15% dry matter at the end of the biological treatment.

It is a well acknowledged fact that steep increases in health expenditures are mainly due to improvements in health technologies as well as the ageing of population combined with mounting societal preferences towards health. This "natural" tendency increasingly faces constraints of public budgets. Therefore, both efficiency and effectiveness considerations have to be put in place in order to allocate financial resources in such a way as to foster optimal results. This can best be done by implementing the analytical tool of health economic evaluations. However, in the Austrian context health economic evaluations only play a minor role as yet. The major hindrance for this unsatisfactory situation is the complex system of health finance which impedes overall considerations beyond the array of particular budgets. PMID:17211767

The present paper aims to investigate the sensitivity of flood peaks to global warming in the Austrian alpine basins. A group of 97 Austrian watersheds, with areas ranging from 14 to 6000 km2 and with average elevation ranging from 1000 to 2900 m a.s.l. have been considered. Annual maximum floods are available for the basins from 1890 to 2007 with two densities of observation. In a first period, until 1950, an average of 42 records of flood peaks are available. From 1951 to 2007 the density of observation increases to an average amount of contemporary peaks of 85. This information is very important with reference to the statistical tools used for the empirical assessment of change over time, that is linear quantile regressions. Application of this tool to the data set unveils trends in extreme events, confirmed by statistical testing, for the 0.75 and 0.95 empirical quantiles. All applications are made with specific (discharges/area) values . Similarly of what done in a previous approach, multiple quantile regressions have also been applied, confirming the presence of trends even when the possible interference of the specific discharge and morphoclimatic parameters (i.e. mean elevation and catchment area). Application of a geomorphoclimatic model by Allamano et al (2009) can allow to mimic to which extent the empirically available increase in air temperature and annual rainfall can justify the attribution of change derived by the empirical statistical tools. An comparison with data from Swiss alpine basins treated in a previous paper is finally undertaken.

Polycyclic aromatic hydrocarbons (PAHs) were measured in pine needles (passive sampling) and on high-volume particulate matter (PM) filters (active sampling) over a period of eight to ten months at two separate sites in the Dayton, Ohio, USA metropolitan area: Moraine and Yellow Springs. Total PAH concentrations for PM ranged from 77.4 μg g-1 to 837 μg g-1 (dry wt.) at both sites with high molecular weight PAHs being the predominant form that tended to be higher in concentration during the colder months. Total PAH concentrations for pine needles varied by tree species and location. With an average concentration of 4187 ng g-1, Austrian pine (Pinus nigra) needles in Moraine ranged from 2543 ng g-1to 6111 ng g-1 (dry wt.) with the lowest and highest concentrations occurring in October and August, respectively. The amount of phenanthrene was extremely high for August, 4200 ± 112, which could have resulted from the close proximity of the tree to the parking lot at a firehouse. White pine (Pinus strobus) needles in Yellow Springs had an average concentration of 384 ng g-1and ranged from 127 ng g-1 to 589 ng g-1 (dry wt.) with September and November, respectively, having the lowest and highest PAH concentrations. The 2- and 3-ring PAHs were the predominant form in P. nigra, while the 4-ring PAHs predominated in P. strobus. Total PAH concentrations in P. nigra were an order of magnitude greater than for P. strobus. A bivariate plot of BaA/(BaA + Chry) versus Flt(Flt + Pyr) allowed the PM and pine needle data to be included in the same source analysis and indicated sources of PM at both sites were biomass and/or coal combustion. This plot also suggested PAHs in Yellow Springs P. strobus originated from petroleum combustion sources, whereas PAHs in Moraine P. nigra originated from petroleum combustion with some sources more aged or remote.
Recent European integration discourses are increasingly structured by neo-racist topoi based on orientalist markers of difference. In the Austrian debate, people of Turkish origin are particularly affected by such ascriptions. They are marked as a group not willing to integrate and culturally not fitting into Austrian society. In this discursive conglomerate, women are identified as oppressed victims, lacking education and being in need of help. Using the biographical narratives of young Aust...

The rise in the rate of inflation during the 1970s was paralleled by a rise in interest in monetarism, which offered the means for controlling inflation. Despite the increased interest, monetarism is still often misunderstood, as Thomas M. Humphrey points out in “On Nonneutral Relative Price Effects in Monetarist Thought: Some Austrian Misconceptions.” Economists of the Austrian school have portrayed monetarism as oblivious to the effects of monetary disturbances on the real economy of output...
The radical subjectivism of the Austrian school of economics is a special case of Dewey’s ways of knowing. Austrian economists adopted an Aristotelian deductive approach to economic issues such as social behavior and exchange. In Dewey’s contrasting view, the scientist commends new, alternative ways of knowing to the scientific community, offering more profound insight or more efficacious practical applications. Alternative ways of knowing which do not offer practical or intellectual benefits...

The Council Directive 96/29/EURATOM lays down the basic safety standards for the protection of the workers and the general public against the dangers arising from ionising radiation, including natural radiation. Based on the directive and on the corresponding Austrian legislation a comprehensive study was conducted to determine the occupational radiation exposure in Upper Austrian water supplies and spas. The study comprises 45 water supplies and 3 spas, one of them being a radon spa. Most measurements taken were to determine the radon concentration in air at different workplaces (n = 184), but also measurements of the dose rate at dehumidifiers (n = 7) and gamma spectrometric measurements of back washing water (n = 4) were conducted. To determine the maximum occupational radon exposure in a water supply measurements were carried out in all water purification buildings and in at least half o f the drinking water reservoirs of the water supply. The results were combined with the respective working times in these locations (these data having been collected by means of a questionnaire). Where the calculated exposure was greater than 1 MBq h/m then all drinking water reservoirs of the concerned water suppl y were measured for their radon concentration to ensure a reliable assessment of the exposure. The results show that the radon concentrations in the water supplies were lower as expected, being in 55% of all measurement sites below 1000 Bq/m in 91% below 5000 Bq/m and with a maximum value of 38700 Bq/m.This leads to exposures that are below 2 MBq h/m (corresponding to approx. 6 mSv/a) in 42 water supplies. However, for the remaining three water supplies maximal occupational exposures due to radon of 2.8 MBq h/m (∼ 10 mSv/a), 15 MBq h/m (∼ 50 mSv/a), and 17 MBq h/m ( ∼ 56 mSv/a), respectively, were determined. In these water supplies remediation measures were proposed, based mainly on improved ventilation of and/or reduction of working time in the building

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
In this paper, we try to promote the building of a Quantitative Austrian Modelling (QAM). QAM must be viewed as a complementary quantitative prolongation of the Austrian methods and as a complementary approach to the already existing quantitative approaches - especially we would like here to answer to the appeal of Prof. N.J.Vriend . As we explain it in the first part, our approach resulted from a critical view of the econometric procedures by Austrian methods and, from a theoretical inst...

Pop musicians performing in black stage costume take advantage of cultural traditions relating to matters black. Stylistically, black is a paradoxical color: although a symbol of melancholy, pessimism, and renunciation, black also expresses minimalist modernity and signifies exclusivity (as...... is hinted by Rudyard Kipling’s illustration of ‘The [Black] Cat That Walked by Himself’ in his classic children’s tale). It was well understood by uniformed Anarchists, Fascists and the SS that there is an assertive presence connected with the black-clad figure. The paradox of black’s abstract elegance......-styled references to, among other things, the culturally and ideologically effervescent interwar-period have made me curious as to what alternative possibilities – for instance ‘emancipation’ – a comparative analysis might disclose concerning the visual rhetoric of black. Thus, in conclusion, it is briefly...

In Austria, the activity deposit per square meter due to the Chernobyl reactor accident ranges between 740 Bq in the northeastern part of Lower Austria and 90761 Bq in Upper Austria. The resulting high Cs-137 concentrations in the Austrian soils make soil to plant transfer studies desireable. Another question, the present work deals with, is to see the influence of K-, Mg- and NH4NO3- applications on the Cs plant uptake. Pot experiments with two contaminated brown soils and a chernozem were conducted. The following mean Cs- transfer factors (FW/DW) were obtained: barley (grains: 0,00094; straw: 0,009), corn (grains: 0,0028; straw: 0,0057), rye (grains: 0,020; straw: 0,048) and endive (0,0028). The transfer factors were hardly influenced by potassium- and magnesium- applications, due to the high clay contents of the soils and the adequate autochthonous supply with potassium and magnesium. NH4NO3- treatments increased the Cs-uptake into rye (grains and straw) distinctly. 13 refs., 3 figs., 4 tabs. (Author)

The technical tools for projecting future energy demand can be grouped into two broad categories: Firstly, time series or cross section data based econometric models which contain information about customers' past behavior and thus enable to judge the causal effects of economic factors like incomes and prices on energy demand (passive forecasting). Secondly, structural simulation models which indicate how energy services transform to flows of useful, final and primary energy. These models enable to estimate the technical potential of improving the energy application and energy transformation systems (active scenario approach). Comparison of the two approaches with respect to projections for future energy demand yields that, typically, in the short run of econometric approach will dominate the structural simulation model. In the long run, however, this relation will be reversed. The econometric models suffer lack of technical information necessary to describe the demand for energy. The structural simulation model enables an incorporation of technical factors like efficiencies and fuel shares. An application of the structural model is a simulation run describing a scenario in order to reduce the Austrian CO2-emissions according to the recommendations of the conference of Toronto
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.
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.
Within an Austrian spruce stand, vertical distribution of radiocaesium in soil as well as 137Cs concentration in different forest ecosystem compartments including spruce and surface water were investigated 10 years after the Chernobyl accident. The total 137Cs inventory in the forest was estimated to be 46 kBq m-2 (ref. date: 86-05-01). From the collected data annual input rates via litterfall of 0.48% per year and output rates through waterflows of only 0.02% per year were derived. The results identify the high importance of forest soils as a sink for radiocaesium. The estimated ecological residence half-times turned out to be highest in the organic soil horizons (1-3 years per cm), whereas in mineral horizons the values decrease significantly. As a consequence, soil inventory represents more than 95% of the total, whereas only approximately 3.3% of the 137Cs inventory is stored in the living biomass of spruce trees and a further 0.5% in the phytomass of understorey vegetation
A monitoring program has been carried out since 1988 in Weinsberger Wald, an Austrian forest stand severely affected by the Chernobyl plume. Analyses of forest soils, understorey vegetation and mushrooms showed that 137Cs values decreased significantly between 1988 and 1993. In ferns, mosses and bilberry sprouts the concentrations did decrease to about 35% of the concentrations measured in 1988, however, seven years after the deposition event, the 137Cs contamination of edible forest products and game browse is still considerable. Derived ecological half-times are the longest in mushrooms (5.8 years), followed by values between 3.1-3.7 years in mosses, ferns and dwarf shrubs. Ecological half-times of 2.1 years were determined in grasses and the shortest values (1.9 years) were found in herbs (Oxalis acetosella). Annual measurements of 137Cs content in soil samples from different layers showed that the 137Cs values decreased in the litter layer, whereas they increased in mineral strata between 1988 and 1993.

Mediterranean pine forests display high resilience after extreme climatic events such as severe droughts. However, recent dry spells causing growth decline and triggering forest dieback challenge the capacity of some forests to recover following major disturbances. To describe how resilient the responses of forests to drought can be, we quantified growth dynamics in plantations of two pine species (Scots pine, black pine) located in south-eastern Spain and showing drought-triggered dieback. Radial growth was characterized at inter- (tree-ring width) and intra-annual (xylogenesis) scales in three defoliation levels. It was assumed that the higher defoliation the more negative the impact of drought on tree growth. Tree-ring width chronologies were built and xylogenesis was characterized 3 years after the last severe drought occurred. Annual growth data and the number of tracheids produced in different stages of xylem formation were related to climate data at several time scales. Drought negatively impacted growth of the most defoliated trees in both pine species. In Scots pine, xylem formation started earlier in the non-defoliated than in the most defoliated trees. Defoliated trees presented the shortest duration of the radial-enlargement phase in both species. On average the most defoliated trees formed 60% of the number of mature tracheids formed by the non-defoliated trees in both species. Since radial enlargement is the xylogenesis phase most tightly related to final growth, this explains why the most defoliated trees grew the least due to their altered xylogenesis phases. Our findings indicate a very limited resilience capacity of drought-defoliated Scots and black pines. Moreover, droughts produce legacy effects on xylogenesis of highly defoliated trees which could not recover previous growth rates and are thus more prone to die. PMID:27066053
A test planting of 30 first- and second-generation pitch x loblolly pine (pinus rigida x P. taeda) hybrids was established on a West Virginia minesoil in 1985. The site was considered orphaned because earlier attempts at revegetation were unsuccessful. The soil was acid (pH 4.6), lacking in nutrients, and compacted. Vegetation present at the time of planting consisted of a sparse cover of tall fescue (Festuca arundinacea) and poverty grass (Danthonia spicata) and a few sourwood (Oxydendrum arboreum) and mountain laurel (Kalmia latifolia) seedlings. In the planting trial, 30 different hybrids were set out in 4 tree linear plots replicated 5 times. The seedlings had been grown in containers for 1 yr before outplanting. Evaluations made after 6 growing seasons showed overall plantation survival was 93%; six hybrids and one open-pollinated cross survived 100%. Individual tree heights ranged from 50 to 425 cm with a plantation average of 235 cm (7.7 ft). Eleven of the hybrids had average heights that exceeded the plantation average. Another test planting of tree and shrub species on this site has very poor survival. Therefore, pitch x loblolly hybrid pine can be recommended for reclaiming this and similar sites

Reproduction and propagation of species are the most important missions of every living organism. For effective species propagation, pine cones fold their scales under wet condition to prevent seeds from short-distance dispersal. They open and release their embedded seeds on dry and windy days. In this study, the micro-/macro-scale structural characteristics of pine cones and pine seeds are studied using various imaging modalities. Since the scales of pine cones consist of dead cells, the folding motion is deeply related to structural changes. The scales of pine cones consist of three layers. Among them, bract scales are only involved in collecting water. This makes pine cones reduce the amount of water and minimize the time spent on structural changes. These systems also involve in drying and recovery of pine cones. In addition, pine cones and pine seeds have advantageous structures for long-distance dispersal and response to natural disaster. Owing to these structural features, pine seeds can be released safely and efficiently, and these types of structural advantages could be mimicked for practical applications. This research was financially supported by the Creative Research Initiative of the Ministry of Science, ICT and Future Planning (MSIP) and the National Research Foundation (NRF) of Korea (Contract grant number: 2008-0061991).

Chinese pine caterpillar (Dendrolimus tabulaeformis)larvae were fed with pine needles of different degrees of damage to evaluate the effects of pine needles on the growth and development of larvae.The results showed that the nutritional index of the larvae declines after feeding on the damaged pine needlings.The lowest amount of food ingested and voided feces,the lowest nutritional index,slowest development,lightest pupae and most mortality were found in those pine caterpillar larvae fed with pine needles which were 50% damaged.The damaged pine needles significantly affected the population dynamics of Chinese pine caterpillars.The nutritional indices of larvae fed with 25% and 75% damaged pine needles were similar.The nutritional index of the dark morphs was higher than that of the tinted morphs,however,their mortality was lower than that of the tinted morphs.This phenomenon was reversed at the later stage of development when the larvae were fed on 50% damaged pine needles.

In later 2007 the Austrian Weather Service (ZAMG) established a group that shall deal with climate change modeling. Two of the group's main goals are to provide climate change scenarios for the assessment of the impact on ecosystems and to reconstruct past climate states along with their change. The former aim is to derive estimates of might happen to our ecosystems under different emission-pathways, whilst the latter goal is to better understand what has caused characteristical changes, which are to be found in proxies. Both aims can be achieved by empirical or dynamical downscaling models, which are ultimately based on the reliability of the driving GCMs results. It is well known that empirical and dynamical downscaling models do have advantages and disadvantages, which are different. As such it appears reasonable to use the approach which is better adapted to the considered question. It may be meaningful to apply empirical downscaling if long periods of time (such as substantial parts of the Holocene) are in the center of attention, whereas dynamical downscaling may be better suited to address questions that are related to decades. Up to now we were more involved with empirical downscaling that helped us to work together with scientists assessing the impact on ecosystems, as for instance, fish in a river (Matulla et al. 2007), forests (Lexer et al. 2002) or phenological phases (Scheifinger et al. 2007). After catching a glimpse of those results, we will turn to dynamical modeling. Here we would like to present findings from case studies, which are related to the more recent past. Our next target is the modelling of possible future climate conditions within the Greater Alpine Region (GAR, see e.g. Auer et al. 2007) as well as some characteristical periods throughout the Holocene as for instance the 8.2k event. This event is to be found in a variety of proxies within and also outside GAR. Auer I., Boehm R., Jurkovic A., Lipa W., Orlik A., Potzmann R., Schoener W

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
Approximately 40000 measurements of indoor radon concentrations were performed in randomly selected homes during the Austrian Radon Project. These measurements were carried out by using long-term measuring devices (SSNTD and Electret detectors) and short-term charcoal detectors with liquid scintillation counting as the method of analysis. In addition to the equilibrium factor, soil gas measurements and quasi-continuous indoor measurements, parallel-measurements with different detector systems in randomly selected homes were also performed. Very different results were occasionally obtained for one and the same room at the same time. This was so not only when comparing the long-term and short-term measuring devices; actually, different long-term detector systems also often showed significant discrepancies in results, although all detector systems had been carefully calibrated and tested in laboratories. The essential conclusion was that during a longer exposure in randomly selected homes, the detectors may be moved, opened, or handled in other unfavourable ways which introduce additional uncertainties in the measuring results. The aim of the Austrian Radon Project was to estimate the radon risk for geographic areas (municipalities). This task is different from the evaluation of the mean radon concentration in a single home. Generally, while long-term measurements (a year or even longer) are necessary to get reliable results for a particular house, this is not so where only the mean indoor radon concentrations for an area are of interest. Observed indoor radon concentrations give information about the actual radon exposures of the inhabitants but not about the radon risk from the ground. The house type, the way the house is constructed, the storey where people live, and some living patterns (ventilation rate etc.) modify the geological risk significantly, although it is the geological situation that has to be primarily taken into account when planning and constructing

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.

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'.

According to the draft of the new European Basic Safety Standards (EU-BSS) all member states are obliged to develop a national radon action plan, to control the long term risks from radon exposure in dwellings, public buildings and workplaces. The National Radon Centre, embedded in the Austrian Agency for Health and Food Safety (AGES), was assigned by the Ministry for Environment (BMLFUW) to develop this Austrian action plan and the strategy behind. This conference contribution discusses where we still have a need for actions and how the new BSS will influence the Austrian radon legislation (reference levels, responsibilities, standards, building law). Currently running and planned projects regarding the radon action plan like developing a national radon data base, definition of radon prone areas by improving the radon map and strategies to increase public radon awareness and involve the building sector are presented.

Understanding the physical and genetic structure of hybrid zones can illuminate factors affecting their formation and stability. In north-central Alberta, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb) form a complex and poorly defined hybrid zone. Better knowledge of this zone is relevant, given the recent host expansion of mountain pine beetle into jack pine. We characterized the zone by genotyping 1998 lodgepole, jack pine, and hybrids f...
The political history of an Austrian referendum in 1978, which led to abandonment of a nuclear power station, is reviewed, and an attempt is made to analyse the reasons for the 'No' vote. Surveys are presented which attempt to classify the yes, no and undecided voters in terms of political views. The effects of the Harrisburg accident on Austrian public opinion is examined and the possibility of accentuated differences between 'for' and 'against' groups is stated. It is noted that success in energy saving may reduce the significance of the atomic energy question. (G.M.E.)

Acetone emission from pine plants (pinus sylvestris) is measured by continuously stirred tank reactor. Under a constant light intensity, acetone emission rates increase exponentially with leaf temperature. When leaf temperature is kept constant, acetone emission increases with light intensity. And acetone emission in darkness is also detected. Acetone emitted from pine is quickly labeled by 13C when the plants are exposed to air with 630 mg/m3 13CO2. However, no more than 20% of acetone is 13C labeled. Acetone emission from pine may be due to both leaf temperature- controlled process and light intensity-controlled process. Based on these understandings, an algorithm is used to describe the short term acetone emission rates from pine.
The volatile compounds of 13 Turkish pine (Pinus brutia Ten.) honey samples were characterized by solid phase microextraction (SPME) analysis, followed by gas chromatography-mass spectrometry (GC-MS) analysis. A total of 42 volatile compounds were identified, but volatile compounds such as nonana1, benzene, 4-hexen-3-ol, alpha-pinene, and 2-heptanone were recognized to be specific floral origin markers of the pine honey. The SPME extraction method was proposed as an alternative way to carry o...

Exotic tree pathogens can cause devastating ecological effects on forests that can be exacerbated when infections increase the likelihood of attack by insects. Current high rates of mortality of whitebark pine (Pinus albicaulis Engelm.) are due to white pine blister rust caused by the exotic fungus, Cronartium ribicola J.C. Fisch, and the native mountain pine beetle (Dendroctonus ponderosae Hopkins). These two mortality agents interact in whitebark pine; mountain pine beetle preferentially selects white pine blister rust-infected whitebark pine over healthy trees, and likelihood of attack has been observed to increase with infection severity. We examined attack and emergence rates, and size and sex ratio of mountain pine beetle in whitebark pines exhibiting varying white pine blister rust infection severities. Mountain pine beetle attack density was lowest on the most severely infected trees, but emergence rates and size of beetles from these trees were greater than those from uninfected and less severely infected trees. Low attack rates on severely infected whitebark pine may indicate these trees have lower defenses and that fewer beetle attacks are needed to kill them. Higher beetle emergence rates from severely infected trees may be due to low intraspecific competition resulting from low attack rates or differences in nutrient quality. PMID:26314009

Pine wood nematode (PWN, Bursaphelenchus xylophilus), originating from North America, causes destructive pine wilt disease. Different pine forest ecosystems have different resistances to B. xylophilus,and after its invasion, the resilience and restoration direction of different ecosystems also varies. In this study, an interpretative structural model was applied for analyzing the response of pine forest ecosystem to PWN disturbance. The result showed that a five-degree multi-stage hierarchical system affected the response of the pine forest ecosystem to PWN disturbance, in which direct affecting factors are resistance and resilience. Furthermore,the analysis to the 2nd, 3rd and 4th degree factors showed that not only does distribution pattern of plant species and pine's ecological features affect the resistance of pine forests' ecosystem, but removal of attacked trees and other measures also influence the resistance through indirectly affecting the damage degree of Monochamus alternatus and distribution pattern of plant species. As for resilience,it is influenced directly by soil factors, hydrology,surrounding species provenance and biological character-istics of the second and jointly dominant species, and the climate factors can also have a direct or indirect effect on it by affecting the above factors. Among the fifth elements,the elevation, gradient and slope direction, topographical factors, diversity of geographical location and improve-ment of prevention technology all influence the response of pine forest ecosystem to PWN disturbance.

Full Text Available Military border of the Austrian Monarchy was formed gradually in border areas for the purpose of defending the border from Turkish invasions. In time, as the international political circumstances have changed, the Border itself also modified its primary function. From the beginning of the 18th century soldiers of the Military Border together with the regular troops of Austrian army participate in all wars in which Austria took part. Thanks to those soldiers the military force of the Austrian Empire was significantly strengthened. Except for military tasks, the Military Border served to a great extent as a defensive corridor that stopped spreading infections diseases, invasions of robberies, smuggling goods from Turkey, as well as deserting and emigration to Turkish territory. Because of great importance that Military Border has had for the Austrian Monarchy, the author in this paper gives a summary review of its development in the military, territorial and administrative-political sense. Special attention was given to the administrative system that was introduced in Border in the second half of the 19th century.

Full Text Available We investigated the responses of collembolan communities to pine afforestation in an area formerly characterized by a mosaic of autochthonous downy oak woodland and steppe meadows. Study sites were selected in mixed stands of black pine and Scots pine and control samples were taken from downy oak stands and open steppe meadows. A total of 1884 Collembola specimens belonging to 66 species were collected. Three species, namely Protaphorura pannonica (Onychiuridae, Tomocerus mixtus (Tomoceridae and Isotoma caerulea (Isotomidae proved to be new to the Hungarian fauna. There are typical Collembola communities which are specific to different habitat types where species of a given composition can only or predominantly be found in that habitat, as well as some basic common species which occur in every habitat. The highest species richness (41 was found in steppe meadows, considerably lower (34 in downy oak forests, reaching the lowest value (25 in pine plantations. Although several forest species present in the oak woodland were completely missing from the pine forests, there was no significant difference between the Collembola diversities of the two forest habitats. The difference became more prominent in collembolan abundance which resulted in less than half of individuals/m2 in pine plantations compared to the soils of downy oak forests, most likely due to the changed soil conditions, especially of humus characteristics, caused by the pine needle litter. Jaccard similarity measure indicated approximately equal similarity (0.24–0.28 for paired comparison, suggesting that a relatively constant 'basic Collembola community' determined by the soil type typical for the area is present; while dissimilarity in communities between sites are partly provided by spatial heterogeneity of open and forest habitats and by the difference of the vegetation type.

Checked climate datasets are a "conditio sine qua non" for all projects that are relevant for environment and climate. In the framework of climate change studies and analysis it is essential to work with quality controlled and trustful data. Furthermore these datasets are used as input for various simulation models. In regard to investigations of extreme events, like strong precipitation periods, drought periods and similar ones we need climate data in high temporal resolution (at least in daily resolution). Because of the historical background - during Second World War the majority of our climate sheets were sent to Berlin, where the historical sheets were destroyed by a bomb attack and so important information got lost - only several climate sheets, mostly duplicates, before 1939 are available and stored in our climate data archive. In 1970 the Central Institute for Meteorology and Geodynamics in Vienna started a first attempt to digitize climate data by means of punch cards. With the introduction of a routinely climate data quality control in 1984 we can speak of high-class-checked daily data (finally checked data, quality flag 6). Our group is working on the processing of digitization and quality control of the historical data for the period 1872 to 1983 for 18 years. Since 2007 it was possible to intensify the work (processes) in the framework of an internal project, namely Austrian Climate Data Rescue and Quality Control. The aim of this initiative was - and still is - to supply daily data in an outstanding good and uniform quality. So this project is a kind of pre-project for all scientific projects which are working with daily data. In addition to routine quality checks (that are running since 1984) using the commercial Bull Software we are testing our data with additional open source software, namely ProClim.db. By the use of this spatial and statistical test procedure, the elements air temperature and precipitation - for several sites in Carinthia - could
Full Text Available Soil-surface CO2 efflux and its spatial and temporal variation were investigated in a southern Mediterranean, mixed pine-oak forest ecosystem on the northern slopes of the Sierra de Guadarrama in Spain from February 2006 to July 2006. Measurements of soil CO2 efflux, soil temperatures, and moisture were conducted in nine 1963-m2 sampling plots distributed in a gradient around the ecotone between Pinus sylvestris L. and Quercus pyrenaica Lam. forest stands. Total soil organic matter, Walkey-Black C, particulate organic matter, organic matter fraction below 53 μm, total soil nitrogen content, total soil organic carbon content, and pH were also measured under three representative mature oak, pine, and mixed pine-oak forest stands. Soil respiration showed a typical seasonal pattern with minimums in winter and summer, and maximums in spring, more pronounced in oak and oak-pine stands. Soil respiration values were highest in pine stands during winter and in oak stands during spring and summer.

Full Text Available We predicted that bird diversity and abundance of some bird species would be higher in old-growth stands than in mature pine stands because of the greater structural diversity in old growth. We also predicted that patch size of stands should be influential. To test these predictions, we modeled counts of 79 bird species from 52 stands in 5 regions in the province of Ontario, Canada in relation to habitat at the local and landscape extents. Neither total species richness nor abundance differed between stand types. No significant difference was found in bird assemblages between stand types using ordination analysis. However, more Neotropical migrants were found in old-growth stands than in mature stands, while the reverse was true for short-distance migrants. Twenty-five species had higher counts in old-growth stands--three significantly so: Brown Creeper Certhia americana, Northern Parula Setophaga americana, and Scarlet Tanager Piranga olivacea. Supercanopy pine (> 60 cm dbh was a significant (P < 0.05 positive predictor for Black-throated Green Warbler Setophaga virens, Northern Parula, and total species richness, while medium/large pine (> 40 cm/dbh was a significant positive predictor for Brown Creeper, Pine Warbler Setophaga pinus, and total species richness. The density of supercanopy and medium/large pine explained a small but significant amount of variation in bird assemblages (1%, after considering age, other tree variables (9%, and landscape metrics. Patch size was significant for Evening Grosbeak Coccothraustes vespertinus and total abundance. According to receiver operating characteristic (ROC thresholds, Brown Creeper required a minimum of 62 stems/ha of medium/large pine. Pileated Woodpecker Dryocopus pileatus and Black-throated Green Warbler required a minimum of 14 and 23 stems/ha of supercanopy pine, respectively. Blackburnian Warbler Setophaga fusca required a minimum stand age of 66 years. Current targets in shelterwood seed

Soil-surface CO2 efflux and its spatial and temporal variation were investigated in a southern Mediterranean, mixed pine-oak forest ecosystem on the northern slopes of the Sierra de Guadarrama in Spain from February 2006 to July 2006. Measurements of soil CO2 efflux, soil temperatures, and moisture were conducted in nine 1963-m2 sampling plots distributed in a gradient around the ecotone between Pinus sylvestris L. and Quercus pyrenaica Lam. forest stands. Total soil organic matter, Walkey-Black C, particulate organic matter, organic matter fraction below 53 microm, total soil nitrogen content, total soil organic carbon content, and pH were also measured under three representative mature oak, pine, and mixed pine-oak forest stands. Soil respiration showed a typical seasonal pattern with minimums in winter and summer, and maximums in spring, more pronounced in oak and oak-pine stands. Soil respiration values were highest in pine stands during winter and in oak stands during spring and summer. Soil respiration was highly correlated with soil temperatures in oak and pine-oak stands when soil moisture was above a drought threshold of 15%. Below this threshold value, soil moisture was a good predictor of soil respiration in pine stands. Greater soil organic matter, particulate organic matter, Walkey-Black C, total organic C, and total N content in pine compared to oak sites potentially contributed to the greater total soil CO2 efflux in these stands during the winter. Furthermore, opposing trends in the organic matter fraction below 53 microm and soil respiration between plots suggest that in oak stands, the C forms are less affected by possible changes in use. The effects of soil properties on soil respiration were masked by differences in soil temperature and moisture during the rest of the year. Understanding the spatial and temporal variation even within small geographic areas is essential to assess C budgets at ecosystem level accurately. Thus, this study bears
Full Text Available This article provides an Austrian overview of the inflation versus deflation debate which has captured the attention of the economics profession in the years following the US housing bust. Much of the Austrian analysis of this debate has focused on the massive expansion of the Federal Reserve’s balance sheet and attendant creation of new reserves. Several Austrian economists have predicted that the creation of new reserves will cause a massive increase in inflation. The money multiplier theory, on which these predictions are based, is criticized and an overview of the Austrian business cycle theory is provided to explain why banks are reluctant to issue new credit. Finally, an analysis of the politics of deflation is provided and a class theory is presented to explain why a policy of controlled credit deflation is more likely than a policy that would result in mass inflation or hyperinflation.

This paper uses the cultural standard framework as its theoretical background as well as the concepts of team development. The emphasis of our research is on those culture standards that have been ident...
The magnitude of sedimentation processes was evaluated using Fallout RadioNuclides 'FRNs' (137Cs and 210Pbex) and the mid-term (13 years) magnitude of erosion rates was quantified through conventional runoff plot measurements in a small Austrian watershed. Our objectives were to measure the magnitude of soil erosion under conventional and conservation cropping practices using runoff plots and to test and validate the potential use of FRNs as soil tracers to assess sedimentation rates under Austrian field conditions
Full Text Available This study is an account of how Serbian Hauzmajstor negotiated and entered into partnership with the Austrian Rustler. 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.
This article examines the cotton manufacturing industry in Lombardy during the period when Austrian rule was being restored in the wake of the Congress of Vienna. It adopts Pollard's emphasis on the regional nature of industrialisation, drawing on the surviving accounts of Francesco Saverio Amman - the Austrian-born founder of a major cotton-mill - and attempts to identify differences and similarities between his career and achievements and those of his many counterparts in the rest of Europe. The article begins by looking at Amman's economic and social advancement, and then discusses the development of his business interests. It concludes by examining how he chose to invest his earnings, both within and without the cotton industry. PMID:19455762

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.

Full Text Available This paper is based on an applied research project, which examines the participation of migrants (first and second generation as professionals in Austrian adult education. We present selected outcomes concerning barriers and encouraging factors in the careers of professionals with migrant background. Our main findings show the importance of the recognition of credentials, of social capital and of strategies to avoid discrimination on behalf of the institutions of adult education. Introducing the analytical perspective of critical whiteness, we conclude that Austrian adult education still has to reflect its own role in terms of white privileges. Finally we point out some approaches and strategies to widening participation and reducing discrimination in the professional field.

Using data from the Austrian retail gasoline market we test the following two hypotheses derived from spatial economics: (i) Retail shops are more densely located in areas with a higher population density. (ii) Spatial competition equilibrium prices are decreasing in the density of seller locations. Both hypotheses are well supported by the data. Population density explains more than 95% of the cross-district variation in the density of gasoline stations. With respect to the relationship betw...

The dominant view in the strategic management field is the resource-based view ("RBV"). It has often been observed that the RBV is lacking in the dynamic dimension. For example, processes of building competitive advantages by means of combining existing complementary resources in novel ways are not inquired into. We argue that the RBV may profitably draw on Austrian (Misesian) and Knightian insights in entrepreneurship and capital theory, particularly in its Lachmannian manifestation, in orde...

In this study, the influence of infection by pine mistletoe (Viscum album L. subsp. austriacum (Wiesb.) Volmann) on the radial growth of crimean pine (Pinus nigra Amold) in Turkey was investigated. We built local residual tree-ring-width chronologies using dendrochronogical techniques. Tree ring chronologies of uninfected (control) crimean pine were used to estimate potential radial growth characteristics in the "infected" crimean pine (light, moderate and severe infection groups). In 2005, increment cores were collected from 26 infected and 19 control dominant or co-dominant trees and annual radial growth indices from 1930-2005 were calculated for each infection group in a 14 point sampling. We compared radial growth in the uninfected trees with mean regional chronology. We found a strong decrease in radial growth in during the 1998-2005 period. The periodic average radial growth reduction (in %) from 1998 to 2005, respectively, were 0 for control, 26 for light, 39 for moderate and 63 for severe infection groups. It can be especially concluded that a severe degree of pine mistletoe attack has a negative effect on radial growth of the infected crimean pine trees. PMID:22167935
Full Text Available Pine wilt disease is a severe threat to the native pine forests in East Asia. Understanding the natural regeneration of the forests disturbed by pine wilt disease is thus critical for the conservation of biodiversity in this realm. We studied the dynamics of composition and structure within different plant functional types (PFTs in Masson pine forests affected by pine wilt disease (PWD. Based on plant traits, all species were assigned to four PFTs: evergreen woody species (PFT1, deciduous woody species (PFT2, herbs (PFT3, and ferns (PFT4. We analyzed the changes in these PFTs during the initial disturbance period and during post-disturbance regeneration. The species richness, abundance and basal area, as well as life-stage structure of the PFTs changed differently after pine wilt disease. The direction of plant community regeneration depended on the differential response of the PFTs. PFT1, which has a higher tolerance to disturbances, became dominant during the post-disturbance regeneration, and a young evergreen-broad-leaved forest developed quickly after PWD. Results also indicated that the impacts of PWD were dampened by the feedbacks between PFTs and the microclimate, in which PFT4 played an important ecological role. In conclusion, we propose management at the functional type level instead of at the population level as a promising approach in ecological restoration and biodiversity conservation.

The present report tries to give a survey of the economic situation of Austrian energy industry after the plebiscite on the Zwentendorf nuclear power plant. Basing on the energy situation before 1978 it deals in particular with the consequences of the plebiscite and points to the revised energy prognoses. Furthermore, the international entanglements of Austria because of its membership in the International Energy Agency is discussed. The calendar of operations of the Austrian Federal Government lists a great deal of measures where an active, in parts a very centralistic energy policy becomes evident. The limits and possibilities of Austrian economic and financial policy are set forth in the chapters dealing with financing and the development of the balance of trade and payment. Austria's policy of neutrality is closely related to these factors. In spite of increasing difficulties, however, it seems feasible to sanitate the existing problems. As in other countries the emotions concerning the peaceful use of nuclear energy is still keeping on in Austria. New decisions shall have to be made next winter or spring. (orig.)

The sustained economic growth trend goes hand in hand with a higher demand from industrialized nations and a stronger internal demand, pushing for better infrastructure. The Austrian economy is also benefiting from booming Asia, underscored by the steady increase of Austrian exports to this region, the rise of foreign direct investment and companies doing business in these countries. The Austrian business community would like to see the South East Asian tiger states more out of the shadow of the new super power China. The overall objective is to intensify the economic integration with South and South East Asia.
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.
The Austrian Waste Management Act (AWG) entered into force on 1 July 1990. Paragraph 1 of the act defines the following objectives: to keep detrimental, unbeneficial or otherwise unhealthy influences on man, as well as on animals, plants, their living conditions and their natural environment as low as possible; to preserve raw material and energy resources; to keep the demand for landfill capacities as low as possible; to ensure that only such materials should remain as waste, the dumping of which does not present any potential hazard for future generations (precautionary principle). The waste management act thus places the highest priority on the protection of human beings and the environment and upon the preservation of natural resources. Accordingly, it must be the aim of waste management to handle waste in such a way that environmental pollution is kept as low as possible by prevention, recovery and disposal. Paragraph 5 of the Austrian waste management act stipulates that the Federal Minister of Agriculture, Forestry, Environment and Water Management has to issue the Federal Waste Management Plan in order to reach the objectives and observing the rules of modern waste management. Following the first waste management plan in 1992 an amendment is required every three years. This is why the Austrian Federal Environment Agency elaborated the following studies: waste generation, recovery and disposal in Austria; hazardous waste and waste oils in Austria; non-hazardous waste in Austria. Further information on waste management facilities in Austria is presented on our homepage (http://www.ubavie.gv.at). (author)

Full Text Available Now let me begin by making a few points on the true origin of the Austrian School of Economics, which should be traced back to the works of the Spanish Scholastics of what is known as the “Siglo de Oro Español” (in english the “Spanish Golden Age”, which ran from the mid 16th century through the 17th century. The great austrian scholar Murray N. Rothbard (one of the brightest followers and pupils of Ludwig von Mises first developed the thesis that the Austrian School is of spanish origin in 1974. The Nobel Prize winner Friedrich A. Hayek shared this view, particularly after meeting Bruno Leoni, the great italian scholar and author of the book, freedom and the law. The two met in the 1950s, and Leoni convinced Hayek that the intellectual origins of classical economic liberalism lay in Mediterranean Europe and not in Scotland.I have here a letter from Hayek dated january 7, 1979, in which Hayek writes that Rothbard “demonstrates that the basic principles of the theory of the competitive market were worked out by the spanish scholastics of the 16th century and that economic liberalism was not designed by the calvinists but by the spanish jesuits.” Hayek concludes his letter by telling us: “i can assure you from my personal knowledge of the sources that Rothbard’s case is extremely strong.”

Tree height, basal diameter, stem form, number, angle and diameter of branches were assessed in eight-year-old provenance test established by 30 seed sources of Scots pine (Pinus sylvestris L.) at Aydogmus and Kemer experimental sites of Southern part of Turkey. Growth of the provenances was also compared to two native species (Taurus cedar- Cedrus libani A. Rich and Black pine-Pinus nigra Arnold.) of the region. Variations within provenance and among provenances, and relations among the traits were estimated. There were large differences (p <= 0.05) within provenance and among provenances for the traits, while sites showed similar (0.05 <= p) performance for tree height and stem form. For instance, average of tree height was 181 cm and varied between 138.3 cm and 229.8 cm in provenances of Aydogmus site, it was 184 cm and ranged from 130 cm to 246.1 cm in that of Kemer site. Averages of tree height of a provenance were 144.4 cm in Aydogmus and 194.5 cm in Kemer. Individual tree height of the provenance varied between 69 cm and 267 cm, and ranged from 51 cm to 280 cm in sites. Averages of tree height were 143.2 cm in Black pine 145.6 cm in Taurus cedar which were natural species of the region. There were mostly positive and significant (p <= 0.05) correlations among the traits. Results of the study were discussed for new plantations and breeding of the species. (author)

A DNA extraction protocol for submerged pine logs was developed with the following properties: (i) high molecular weight DNA, (ii) PCR amplification of chloroplast and nuclear sequences, and (iii) high sequence homology to voucher pine specimens. The DNA extraction protocol was modified from a cetyltrimehtylammonium bromide (CTAB) protocol by adding stringent electrophoretic purification, proteinase K, RNAse, polyvinyl pyrrolidone (PVP), and Gene Releaser. Chloroplast rbcL (ribulose-1,5-bisphosphate carboxylase) could be amplified. Nuclear ribosomal sequences had >95% homology to Pinus taeda and Pinus palustris. Microsatellite polymorphism for PtTX2082 matched 2 of 14 known P. taeda alleles. Our results show DNA analysis for submerged conifer wood is feasible. PMID:15499414
During the autumn of 1991, a Scots pine forest, Tisvilde Hegn, was investigated with respect to the distribution of radiocesium on compartments in the forest ecosystem. The sandy acidic soil is poor, with a approximately 5-cm thick layer of organic soil, and clay content is very low, between 0 and...... included. The concentrations of radiocesium are highest in the endshoots of the pine trees, and lowest in the hardwood. There are indications that the Chernobyl cesium is mainly distributed in the parts of the tres that have been formed since 1986. Observed Ratios (OR) were used to characterize the ability...... 2%. Cesium from Chernobyl is still totally in the upper 5 cm, while almost half of the fallout cesium has penetrated to depths lower than 5 cm. More than 95% of the total amount of Cs-137 is in the soil compartment. The rest is mainly in the trees (3.4%) and vegetation (0.4%), moss and lichen...

In order to analyze the effects of the temperature gradient on moisture movement during the highly intensive microwave-vacuum drying, thermal diffusion of Masson pine wood was studied. Internal distribution of temperature and moisture in Masson pine samples sealed by epoxy resin and aluminum foil was measured, the magnitude of thermal diffusion was calculated and the influencing factors of thermal diffusion were discussed. Results showed that with the transfer of moisture toward the low temperature in wood, opposite temperature and moisture gradient occurred. The initial moisture content (MC), temperature and time are important factors affecting this process; the thermal diffusion is in proportion to wood temperature, its initial moisture and time. The temperature and distance from hot surface is strongly linearly correlated, and the relationship between MCs at different locations and distance from the hot end surface changes from logarithmically form to exponentially form with the increase in experimental time.

Full Text Available Microwave radiation to intensify the process of carboxymethylation of pine wood without prior separation of the individual components is proposed to use . Carboxymethylated pine wood in the form of the potassium salt obtained by treating the pine potassium hydroxide and monochloroacetic acid in 2-propanol . Composition and properties of the products were investigated . Carboxymethylcellulose isolated from carboxymethylated pine wood. Increasing the power of microwave radiation (210 to 700 W and the duration of the first and second stages of the process of carboxymethylation (20-30 sec increases the content of carboxymethyl groups (18,3-25,6 %. Abnormally low solubility of the potassium salts of carboxymethylated pine wood (10–18% compared to the sodium salt with a comparable content of carboxymethyl groups was detected. Study viscosity of aqueous solutions carboxymethylated pine and carboxymethylcellulose derived from it was performed. It is shown that the samples obtained at microwave power of 210 W have abnormal flow curves.

Here we describe 5 cases of molar malocclusions in adult pine voles (Microtus pinetorum) used for behavioral endocrinology studies. This species belongs to the subfamily Microtinae, which possess aradicular hypsodont molars. The abnormal molars identified caused apparent difficulty in mastication, resulting in poor body condition necessitating euthanasia. Postmortem examination of the oral cavity revealed grossly elongated mandibular and maxillary molars with abnormal wear at occlusal surface...
