    2006-01-01

    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.

  7. Model-Based Estimation of Forest Canopy Height in Red and Austrian Pine Stands Using Shuttle Radar Topography Mission and Ancillary Data: a Proof-of-Concept Study

    2007-04-06

    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

    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.

  4. Modeling site productivity of anatolian black pine stands in response to site factors in buldan district, turkey

    International Nuclear Information System (INIS)

    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)

    [1] 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), ...

  7. The Austrian radon project

    International Nuclear Information System (INIS)

    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.)

  8. Austrian natural scientists in exile

    International Nuclear Information System (INIS)

    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.

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 no-further-investigation (NFI) reports. Groundwater sampling was also conducted to support a Parcel 21d decision. Based on available data West Black Oak Ridge, East Black Oak Ridge, McKinney Ridge, and West Pine Ridge are not impacted by site operations and are not subject to actions per the Federal Facility Agreement (FFA). This determination is supported by visual inspections, records searches and interviews, groundwater conceptual modeling, approved NFI reports, analytical data, and risk analysis results.

    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

    2011-05-01

    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 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.

    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.

    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.

  3. Austrian emission inventory for dust

    International Nuclear Information System (INIS)

    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

    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.

    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.

  20. THE ECOLOGIST SPIRIT UNDERNEATH AUSTRIAN ECONOMIST CLOTHES

    Directory of Open Access Journals (Sweden)

    Elena Bianca Vieru

    2012-12-01

    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.

  1. HORA - an Austrian platform for natural hazards

    2009-04-01

    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

  2. Austrian tritium monitoring network - annual report 1993

    International Nuclear Information System (INIS)

    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)

    2007-01-01

    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

(*)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

    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

  18. Assessment of sustainability in Austrian wine production

    2015-01-01

    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.

  19. Natural radionuclides in Austrian bottled mineral waters

    International Nuclear Information System (INIS)

    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)

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

    Directory of Open Access Journals (Sweden)

    Nicolai J. Foss

    2009-10-01

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

  3. On the way to an Austrian radon action plan

    International Nuclear Information System (INIS)

    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.

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

  6. An Austrian framework for PET quality control

    International Nuclear Information System (INIS)

    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

  17. Acidification and Nitrogen Eutrophication of Austrian Forest Soils

    Directory of Open Access Journals (Sweden)

    Robert Jandl

    2012-01-01

    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.

  18. Changes in Woodland Use from Longleaf Pine to Loblolly Pine

    Directory of Open Access Journals (Sweden)

    John Schelhas

    2010-08-01

    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.

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

    Directory of Open Access Journals (Sweden)

    Nikolić Dušan

    2011-01-01

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

    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.

    2004-01-01

    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 ...

  8. Austrian meat: Authenticity control by stable isotope analysis

    International Nuclear Information System (INIS)

    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

  9. Austrian Economics - The Ultimate Achievement of an Intellectual Journey

    Directory of Open Access Journals (Sweden)

    Pascal Salin

    2009-01-01

    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.

The rational expectations hypothesis is, however, evaluated rather critically concluding it is quite strong and unrealistic ...

  12. State aid in the Austrian electricity industry law

    International Nuclear Information System (INIS)

    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

  13. Hydrogeological interpretation of natural radionuclide contents in Austrian groundwaters

    Schubert, Gerhard; Berka, Rudolf; Hörhan, Thomas; Katzlberger, Christian; Landstetter, Claudia; Philippitsch, Rudolf

    2010-05-01

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

  18. 69 The Multicultural Education in Bucovina during the Austrian Domination

    Directory of Open Access Journals (Sweden)

    Vasile Baltag

    2014-12-01

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

    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

    International Nuclear Information System (INIS)

    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)

    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…

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

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

  4. A Thought Experiment Comparing Austrian and Keynesian Stimulus Packages

    Directory of Open Access Journals (Sweden)

    Wladimir Kraus

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

  9. Investigations of biological processes in Austrian MBT plants

    International Nuclear Information System (INIS)

    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.

    2006-12-01

    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

    2016-04-01

    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.

    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.

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...

  1. Occupational radiation exposure in upper Austrian water supplies and Spas

    International Nuclear Information System (INIS)

    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

    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.

  6. Cs-137 transfer into plants from contaminated Austrian soils

    International Nuclear Information System (INIS)

    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)

  8. Structures and perspectives of the Austrian energy system

    International Nuclear Information System (INIS)

    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.

  10. Cornerstones of the Austrian radon risk communication strategy

    International Nuclear Information System (INIS)

    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.

  11. Distribution of radiocaesium in an Austrian forest stand

    International Nuclear Information System (INIS)

    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

  12. Assessment of radiocaesium behaviour in an Austrian forest ecosystem

    International Nuclear Information System (INIS)

    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

  16. Hybrid pine for tough sites

    International Nuclear Information System (INIS)

    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.

    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.

  19. Climate Modeling at the Austrian Weather Service (ZAMG)

    2009-05-01

    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

  20. An inventory of glacial lakes in the Austrian Alps

    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

  1. What did we learn from the Austrian radon project?

    International Nuclear Information System (INIS)

    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.

  4. Impacts of Austrian Climate Variability on Honey Bee Mortality

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

    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.

    SHAO; Min; (邵敏); Jürgen; Wildt

    2002-01-01

    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.

    Dooley, Edith M; Six, Diana L

    2015-10-01

    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.

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.

  11. Effects of Afforestation with Pines on Collembola Diversity in the Limestone hills of Szárhalom (West Hungary

    Directory of Open Access Journals (Sweden)

    TÓTH, Viktória

    2012-01-01

    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

    2007-01-01

    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.

  18. Avian Assemblages Differ between Old-Growth and Mature White Pine Forests of Ontario, Canada: A Role for Supercanopy Trees?

    Directory of Open Access Journals (Sweden)

    David Anthony Kirk

    2012-06-01

    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

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

  20. Why Credit Deflation Is More Likely than Mass Inflation: An Austrian Overview of the Inflation Versus Deflation Debate

    Directory of Open Access Journals (Sweden)

    Vijay Boyapati

    2010-12-01

    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 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

    Directory of Open Access Journals (Sweden)

    Janković Ivan

    2006-01-01

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

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.

    2011-05-01

    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

    Guang Hu

    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.

  14. The economic situation of Austrian power industry after the plebiscite on nuclear power plants

    International Nuclear Information System (INIS)

    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.)

  16. Changes in equipment and image quality. Impact of one year Austrian breast cancer early detection programme

    International Nuclear Information System (INIS)

    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.

  17. Hazardous wastes and waste oils in Austria. Compiled for the Austrian Federal Waste Management Plan 2001

    International Nuclear Information System (INIS)

    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)

  18. THE ESSENCE OF THE AUSTRIAN SCHOOL AND THE CONCEPT OF DYNAMIC EFFICIENCY

    Directory of Open Access Journals (Sweden)

    Jesus Huerta DE SOTO

    2011-01-01

    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.”

  3. Provenance variations of scots pine (Pinus sylvestris L.) in the Southern PART of Turkey

    International Nuclear Information System (INIS)

    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

    2005-01-01

    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.

    Berry, Mark E.

    2001-11-01

    Pine Creek Ranch was purchased in 1999 by the Confederated Tribes of Warm Springs using Bonneville Power Administration Fish and Wildlife Habitat Mitigation funds. The 25,000 acre property will be managed in perpetuity for the benefit of fish and wildlife habitat. Major issues include: (1) Restoring quality spawning and rearing habitat for stealhead. Streams are incised and fish passage barriers exist from culverts and possibly beaver dams. In addition to stealhead habitat, the Tribes are interested in overall riparian recovery in the John Day River system for wildlife habitat, watershed values and other values such as recreation. (2) Future grazing for specific management purposes. Past grazing practices undoubtedly contributed to current unacceptable conditions. The main stem of Pine Creek has already been enrolled in the CREP program administered by the USDA, Natural Resource Conservation Service in part because of the cost-share for vegetation restoration in a buffer portion of old fields and in part because of rental fees that will help the Tribes to pay the property taxes. Grazing is not allowed in the riparian buffer for the term of the contract. (3) Noxious weeds are a major concern. (4) Encroachment by western juniper throughout the watershed is a potential concern for the hydrology of the creek. Mark Berry, Habitat Manager, for the Pine Creek Ranch requested the Team to address the following objectives: (1) Introduce some of the field staff and others to Proper Functioning Condition (PFC) assessments and concepts. (2) Do a PFC assessment on approximately 10 miles of Pine Creek. (3) Offer management recommendations. (4) Provide guidelines for monitoring.

    Terrestrial arthropods in forests are engaged in vital ecosystem functions that ultimately help maintain soil productivity. Repeated disturbance can cause abrupt and irreversible changes in arthropod community composition and thereby alter trophic interactions among soil fauna. An increasingly popular means of generating income from pine plantations in the Southeastern U.S. is annual raking to collect pine litter. We raked litter once per year for three consecutive years in the pine plantatio...

  15. Pine Gene Discovery Project - Final Report - 08/31/1997 - 02/28/2001; FINAL

    International Nuclear Information System (INIS)

    Integration of pines into the large scope of plant biology research depends on study of pines in parallel with study of annual plants, and on availability of research materials from pine to plant biologists interested in comparing pine with annual plant systems. The objectives of the Pine Gene Discovery Project were to obtain 10,000 partial DNA sequences of genes expressed in loblolly pine, to determine which of those pine genes were similar to known genes from other organisms, and to make the DNA sequences and isolated pine genes available to plant researchers to stimulate integration of pines into the wider scope of plant biology research. Those objectives have been completed, and the results are available to the public. Requests for pine genes have been received from a number of laboratories that would otherwise not have included pine in their research, indicating that progress is being made toward the goal of integrating pine research into the larger molecular biology research community

    The black liquor properties program has been conducted over this last period so as to systematically collect data on properties, liquor composition, and lignin characteristics very carefully by methods that have developed during this program. Complete data has been collected for Slash Pine black liquors made by experimental pulping at different pulping conditions. In addition, data has been collected for mill liquors and partial properties or composition data has been collected on Slash Pine black liquors. Data reduction methods have been developed or extended for correlation of viscosity, heat capacity, heat of dilution, and density. Correlation of properties to pulping conditions and of composition to. pulping conditions has begun. In most cases, data reduction methods have been developed that are fundamentally based and that have been shown to be generally applicable to all black liquors. In the near future, we fully expect to accomplish our goal of developing generalized correlations relating physical properties of Slash Pine kraft black liquors to liquor composition. This interim report reviews the methods used, describes examples of data reduction methods that have been developed, and presents some preliminary results for correlation of liquor composition and properties to pulping conditions for Slash Pine black liquors.

    Geodesic completeness needs existence near the horizon of the black hole of "white hole" geodesics coming from the region inside of the horizon. Here we give the classification of all such geodesics with the energies $E/m \\le 1$ for the Schwarzschild and Kerr's black hole. The collisions of particles moving along the "white hole" geodesics with those moving along "black hole" geodesics are considered. Formulas for the increase of the energy of collision in the centre of mass frame are obtained and the possibility of observation of high energy particles arriving from the black hole to the Earth is discussed.

  4. The relevance and legibility of radio/TV weather reports to the Austrian public

    2013-03-01

    The communicative quality of media weather reports, especially warnings, can be evaluated by user research. It is an interdisciplinary field, still uncoordinated after 35 years. The authors suggest to shift from a cognitive learning model to news processing, qualitative discourse and usability models as the media audience is in an edutainment situation where it acts highly selective. A series of field surveys 2008-2011 tested the relevance and legibility of Austrian radio and television weather reports on fair weather and in warning situations. 247 laypeople heard/saw original, mostly up-to-date radio/TV weather reports and recalled personally relevant data. Also, a questionnaire on weather knowledge was answered by 237 Austrians. Several research hypotheses were tested. The main results were (a) a relatively high level of meteorological knowledge of the general population, with interest and participation of German-speaking migrants, (b) a pluralistic media usage with TV, radio and internet as the leading media, (c) higher interest and attention (also for local weather) after warnings, but a risk of more false recalls after long warnings, (d) more recall problems with radio messages and a wish that the weather elements should always appear in the same order to faciliate processing for the audience. In their narrow time windows, radio/TV weather reports should concentrate on main features (synoptic situation, tomorrow's temperature and precipitation, possible warnings), keep a verbal “speed limit” and restrict show elements to serve the active, selective, multioptional, multicultural audience.

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

  6. EVALUATIVE DESCRIPTION OF THE PERSON’S MENTAL ABILITIES IN THE AUSTRIAN NATIONAL VARIANT OF GERMAN

    Directory of Open Access Journals (Sweden)

    Rebrina Larisa Nikolaevna

    2014-09-01

    Full Text Available The national variant of language is studied as a metasystem of all variations of the national language, as a parity form of language existence and adapting to its functioning conditions. In the article the paradigmatic class of lexical items in the Austrian national variant of German, which are used to evaluate a person in terms of their mental abilities, are studied. The inner structure of this class incorporates two subclasses of lexical items, which actualize positive and negative evaluations. The onomasiological approach allows to define subject codes as nomination motivating factors. Subject codes point to identification spheres of a certain object, generate images and metaphorical shifts, allow to determine the elements of the mental processes and their features relevant for positive or negative evaluation. The results of linguistic analysis reveal that in comparison to the negative evaluation, the positive one is less completely represented in the lexical and semantic system of the Austrian national variant of German. Relevant features for an evaluative description of person's mental abilities are temporal and qualitative characteristics of mental processes, quantitative characteristics of objects, qualitative characteristics of a person, such as age, physical, social and gender. The most productive subject codes are objective, zoological, botanical, physiological and anatomical codes. The spatial and temporal subject codes are less productive.

    Kunze, Ursula; Kunze, Michael

    2015-09-01

    This paper describes a paradoxical situation in Austria. The vaccination rate against tick-borne encephalitis (TBE) in the general population is 82%, which is the highest worldwide, whereas the vaccination rate against influenza is about 8% and is among the lowest worldwide. A high awareness of TBE among the Austrian population achieved by an annual social marketing programme and the wide use of effective and well-tolerated vaccines have led to a successful containment of that disease. The vaccination coverage increased from 6% in 1980 to 82% in 2013 and exceeds 90% in some high-risk areas. This has led to a steady decline in the number of TBE cases from several hundred cases to 50 to 100 cases per year. The situation in regard to influenza vaccination is the opposite. Although Austria has issued one of the most extensive recommendations for influenza vaccination worldwide, the vaccination rate of the general population is extremely low. The possible reasons for the failure in the implementation of recommendations are ignorance, lack of social marketing and the predominance of a distinct discordance within the health system in general, and the Austrian medical fraternity in particular.

  8. Integrated environmental protection obligations under European law, survey analysis of Austrian legislation

    International Nuclear Information System (INIS)

    This work focuses on legal instruments serving integrated environmental protection, especially with respect to administrative procedures concerning plant permits, and their inhorent limits. Initially, the legal and scientific approach pursued under the notion of 'integrated environmental protection' and 'environmental impact assessment' is examined and clarified in chapter A. Based thereon, chapter B deals with the obligations resulting from the EIA-Directive and - compared therewith - from the IPPC-Directive with regard to procedures for plant permits. Further, Austria's delay in fully transposing these directives is examined. When dealing with the constitutional basis for transposing the EIA- and IPPC-D into Austrian administrative law (chapter C), the inherent limits of some competence of legislation are discovered to be too narrow to ensure full compliance with EC law; only with regard to EIA, legistation is based on sound constitutional ground. The second part of the work is devoted to three areas of discussion on EIA- and IPPC-procedures under Austrian law: the scope of their applicability (chapter D), the problems of integrated evaluation and the limits of ecological expertise (chapter E) and aspects of public participation (chapter F). The study is concluded by a summary of the main results (chapter G). (author)

    Full Text Available The current mountain pine beetle (MPB (Dendroctonous ponderosae Hopkins epidemic has severely affected pine forests of Western Canada and killed millions of hectares of lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm. forest. Generally, MPB attack larger and older (diameter > 20 cm or >60 years of age trees, but the current epidemic extends this limit with attacks on even younger and smaller trees. The study’s aim was to investigate the extent of MPB attack in young pine stands and its possible impact on stand dynamics. Although MPB attacks were observed in trees as small as 7.5 cm diameter at breast height (DBH and as young as 13 years old, the degree of MPB attack (percent stems ha−1 increased with increasing tree diameter and age class (13–20, 21–40, 41–60, and 61–80 years old (6.4%, 49.4%, 62.6%, and 69.5% attack, respectively, by age class which is greater than that reported from previous epidemics for stands of this age. The mean density of surviving residual structure varied widely among age classes and ecological subzones. Depending on age class, 65% to 77% of the attacked stands could contribute to mid-term timber supply. The surviving residual structure of young stands offers an opportunity to mitigate the effects of MPB-attack on future timber supply, increase age class diversity, and enhance ecological resilience in younger stands.

    Full Text Available Abstract Background Pinus pinaster is an economically and ecologically important species that is becoming a woody gymnosperm model. Its enormous genome size makes whole-genome sequencing approaches are hard to apply. Therefore, the expressed portion of the genome has to be characterised and the results and annotations have to be stored in dedicated databases. Description EuroPineDB is the largest sequence collection available for a single pine species, Pinus pinaster (maritime pine, since it comprises 951 641 raw sequence reads obtained from non-normalised cDNA libraries and high-throughput sequencing from adult (xylem, phloem, roots, stem, needles, cones, strobili and embryonic (germinated embryos, buds, callus maritime pine tissues. Using open-source tools, sequences were optimally pre-processed, assembled, and extensively annotated (GO, EC and KEGG terms, descriptions, SNPs, SSRs, ORFs and InterPro codes. As a result, a 10.5× P. pinaster genome was covered and assembled in 55 322 UniGenes. A total of 32 919 (59.5% of P. pinaster UniGenes were annotated with at least one description, revealing at least 18 466 different genes. The complete database, which is designed to be scalable, maintainable, and expandable, is freely available at: http://www.scbi.uma.es/pindb/. It can be retrieved by gene libraries, pine species, annotations, UniGenes and microarrays (i.e., the sequences are distributed in two-colour microarrays; this is the only conifer database that provides this information and will be periodically updated. Small assemblies can be viewed using a dedicated visualisation tool that connects them with SNPs. Any sequence or annotation set shown on-screen can be downloaded. Retrieval mechanisms for sequences and gene annotations are provided. Conclusions The EuroPineDB with its integrated information can be used to reveal new knowledge, offers an easy-to-use collection of information to directly support experimental work (including

  11. Water demand for ski resort development in the Austrian Alps: an Overview

    Breiling, M.; Sokratov, S.

    2012-04-01

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

  13. Nitrogen cycling responses to mountain pine beetle disturbance in a high elevation whitebark pine ecosystem.

    Directory of Open Access Journals (Sweden)

    Megan P Keville

    Full Text Available Ecological disturbances can significantly affect biogeochemical cycles in terrestrial ecosystems, but the biogeochemical consequences of the extensive mountain pine beetle outbreak in high elevation whitebark pine (WbP (Pinus albicaulis ecosystems of western North America have not been previously investigated. Mountain pine beetle attack has driven widespread WbP mortality, which could drive shifts in both the pools and fluxes of nitrogen (N within these ecosystems. Because N availability can limit forest regrowth, understanding how beetle-induced mortality affects N cycling in WbP stands may be critical to understanding the trajectory of ecosystem recovery. Thus, we measured above- and belowground N pools and fluxes for trees representing three different times since beetle attack, including unattacked trees. Litterfall N inputs were more than ten times higher under recently attacked trees compared to unattacked trees. Soil inorganic N concentrations also increased following beetle attack, potentially driven by a more than two-fold increase in ammonium (NH₄⁺ concentrations in the surface soil organic horizon. However, there were no significant differences in mineral soil inorganic N or soil microbial biomass N concentrations between attacked and unattacked trees, implying that short-term changes in N cycling in response to the initial stages of WbP attack were restricted to the organic horizon. Our results suggest that while mountain pine beetle attack drives a pulse of N from the canopy to the forest floor, changes in litterfall quality and quantity do not have profound effects on soil biogeochemical cycling, at least in the short-term. However, continuous observation of these important ecosystems will be crucial to determining the long-term biogeochemical effects of mountain pine beetle outbreaks.

    Full Text Available Pine resin, one type of non-timber forest products (NTFPs, is important for Indonesia.   In addition to its high economic value, pine resin also has bright domestic and international market prospects.  Utilization of commercial pine resin has been carried out in Indonesia, but the forest road network required for extracting pine resin has not been specifically planned. To date, the planning and selection of forest road network  in  forest management in Indonesia are intended only for the extraction of  timber products and have not been integrated with the use of NTFPs; also,  they have not considered the economic, ecological, and social aspects a whole. Planning and selection of forest road network have focused more on economic aspects only. This study aimed at planning and assessing the forest road network for extracting pine resin by considering the economic, ecological, and social criteria.  Decision-making method used  to select the best  forest road network was utility analysis.  Indicator used  included road length, road density, a correction factor for manual carrying of pine resin, pine resin carrying distance, road construction cost, and productivity of carrying and extracting pine resin. The result of  the utility analysis indicates that an alternative of forest road network for extracting pine resin has no the whole best indicators, but it has the highest utility value.  This study suggested that the use of the utility analysis help the decision makers to selects process for forest  road network alternative easily and rapidly.Keywords: pine  resin,  forest  road network, utility analysis, non-timber  forest products  (NTFPs

    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 from British Columbia, Alberta, Saskatchewan, Ontario, and Minnesota at 11 microsatellites. Using Bayesian algorithms, we calculated genetic ancestry and used this to model the relationship between species occurrence and environment. In addition, we analyzed the ancestry of hybrids to calculate the genetic contribution of lodgepole and jack pine. Finally, we measured the amount of gene flow between the pure species. We found the distribution of the pine classes is explained by environmental variables, and these distributions differ from classic distribution maps. Hybrid ancestry was biased toward lodgepole pine; however, gene flow between the two species was equal. The results of this study suggest that the hybrid zone is complex and influenced by environmental constraints. As a result of this analysis, range limits should be redefined. PMID:23346232

  17. Black market

    International Nuclear Information System (INIS)

    One way for states and subnational groups to acquire material, knowledge and equipment necessary to build a nuclear weapon or device are illegal transactions. These were singular in the past and did not cause the development of a nuclear black market. But all necessary components of a functioning black market exist. Therefore the further spread and extension of the use of nuclear power would enhance the threat of a nuclear black market, if the trade and use of specific nuclear material is not abandoned worldwide.

  18. Combining IPPC and emission trading: An assessment of energy efficiency and CO2 reduction potentials in the Austrian paper industry

    International Nuclear Information System (INIS)

    In the frame of an innovative project partnership E.V.A. - the Austrian Energy Agency accompanied the Austrian paper industry for the last 2.5 years in developing a branch specific climate change strategy. Within the scope of this project an assessment of the energy efficiency status of the branch was carried out as well as an evaluation of still realisable energy savings and CO2 reduction potentials. The paper presents the methodology applied, which combines a top down approach (benchmarking and best practice) with a bottom up approach (on-site interviews and energy audits), supported by a huge data collection process. Within the benchmarking process all Austrian paper industry installations affected by the EU emission trading directive were benchmarked against their respective IPPC/BAT values. Furthermore an extensive list of best practice examples derived from existing or ongoing studies was compared with the energy efficiency measures already carried out by the companies ('early actions'). These theory-oriented findings were complemented by several on-site interviews with the respective energy managers as well as by detailed energy audits carried out by a consulting company, covering in total more than 80% of the Austrian paper industry's CO2 emissions. The paper concludes with the main results of the project, presenting the pros and cons of working with IPPC documents and BAT values in terms of energy efficiency assessments. Recommendations are presented on how to improve the allocation exercise for the next emission trading period from 2008 to 2012

    2015-04-01

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

Data reduction methods have been developed or extended for correlation of viscosity, heat capacity, heat of dilution, and density. Correlation of properties to pulping conditions and of composition to pulping conditions has begun. In most cases, data reduction methods have been developed that are fundamentally based and that have been shown to be generally applicable to all black liquors. While it has not proven to be possible to include research for comprehensive correlations for properties for liquors from other species, we have shown that the behavior of liquors made from other species is similar to that which has been explored extensively for Slash Pine liquors. This report reviews the methods used, describes examples of data reduction methods that have been developed, and presents some preliminary results for correlation of liquor composition and properties to pulping conditions for Slash Pine black liquors.

    Full Text Available Terrestrial arthropods in forests are engaged in vital ecosystem functions that ultimately help maintain soil productivity. Repeated disturbance can cause abrupt and irreversible changes in arthropod community composition and thereby alter trophic interactions among soil fauna. An increasingly popular means of generating income from pine plantations in the Southeastern U.S. is annual raking to collect pine litter. We raked litter once per year for three consecutive years in the pine plantations of three different species (loblolly, Pinus taeda; longleaf, P. palustris; and slash, P. elliottii. We sampled arthropods quarterly for three years in raked and un-raked pine stands to assess temporal shifts in abundance among dominant orders of arthropods. Effects varied greatly among orders of arthropods, among timber types, and among years. Distinct trends over time were apparent among orders that occupied both high trophic positions (predators and low trophic positions (fungivores, detritivores. Multivariate analyses demonstrated that raking caused stronger shifts in arthropod community composition in longleaf and loblolly than slash pine stands. Results highlight the role of pine litter in shaping terrestrial arthropod communities, and imply that repeated removal of pine straw during consecutive years is likely to have unintended consequences on arthropod communities that exacerbate over time.

    Full Text Available A study on the removal of cadmium ions from aqueous solutions by pine cone was conducted in batch conditions. Kinetic data and equilibrium removal isotherms were obtained. The influence of different experimental parameters such as contact time, initial concentration of cadmium, pine cone mass and particle size, and temperature on the kinetics of cadmium removal was studied. Results showed that the main parameters that played an important role in removal phenomenon were initial cadmium concentration, particle size and pine cone mass. The necessary time to reach equilibrium was between 4 and 7 hours based on the initial concentration of cadmium. The capacity of cadmium adsorption at equilibrium increased with the decrease of pine cone particle size. The capacity of cadmium adsorption at equilibrium by pine cone increased with the quantity of pine cone introduced (1–4 g/L. Temperature in the range of 20-30°C showed a restricted effect on the removal kinetics (13.56 mg/g at 20°C and a low capacity of adsorption about 11.48 mg/g at 30°C. The process followed pseudo second-order kinetics. The cadmium uptake of pine cone was quantitatively evaluated using adsorption isotherms. Results indicated that the Langmuir model gave a better fit to the experimental data in comparison with the Freundlich equation.

  6. Austrian Business Cycle Theory: Are 100 Percent Reserves Sufficient to Prevent a Business Cycle?

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

  7. A geostatistical autopsy of the Austrian indoor radon survey (1992-2002)

    International Nuclear Information System (INIS)

    Indoor radon (Rn) concentrations have been measured intensively in many countries to assess the burden of diseases associated with exposure to this radioactive gas. So-called radon-risk maps have consequently been produced to delineate areas with high levels. Geostatistical techniques are commonly used nowadays to map a range of environmental variables, in particular to generate probability maps of exceeding a given threshold. However, very few case studies in which indoor radon measurements have been investigated using geostatistical techniques have been published so far. By analyzing around 12,000 Rn measurements made in Austrian ground floors during a 10-year survey, we aim here to review and discuss the potential of geostatistics for mapping an environmental variable that shows very strong local variability. In particular, we show how kriging of the scale components can shed new light on various factors that affect the very high spatial variability of the variable

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

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

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

    Since the 1960s, Austrian fire brigades have been involved in radiation protection. With the preparations for the NPP Zwentendorf and the building of the research reactor in Seibersdorf, the first radiation protection units of the fire brigade were founded. 45 years later: The NPP Zwentendorf never saw its start-up, the use of nuclear energy for the production of electricity is prohibited by a constitutional law, and the research reactor is being decommissioned. What's left are the radiation protection units of the fire brigades. The contribution gives an overview of similarities and differences of the radiation protection units in the nine federal states of Austria, with a special focus on equipment, training and organisation. Nation-wide guidelines and regulations for the tactics of first responders at radiological emergencies are presented and a couple of incidents will be analysed. (orig.)

  12. Comprehensive investigation of radon exposure in Austrian tourist mines and caves

    International Nuclear Information System (INIS)

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

    2013-04-01

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

  14. Total-reflection X-ray fluorescence analysis of Austrian wine

    International Nuclear Information System (INIS)

    The concentration of major, minor and trace elements in Austrian wine was determined by total-reflection X-ray fluorescence using gallium as internal standard. A multi-elemental analysis was possible by pipetting 6 μl of wine directly on the reflector and drying. Total-reflection X-ray fluorescence analysis was performed with Atomika EXTRA II A (Cameca) X-rays from a Mo tube with a high-energy cut-off at 20 keV in total-reflection geometry. The results showed that it was possible to identify only by the elemental analysis as fingerprint the vineyards and year of vintage among 11 different wines

    Soil taxation and soil classification are important drivers of soil science in Austria. However, the tasks are quite different: whereas soil taxation aims at the evaluation of the productivity potential of the soil, soil classification focusses on the natural development and - especially nowadays - on functionality of the soil. Since the foundation of the Austrian Soil Science Society (ASSS), representatives both directions of the description of the soil have been involved in the common actions of the society. In the first years it was a main target to improve and standardize field descriptions of the soil. Although both systems differ in the general layout, the experts should comply with identical approaches. According to this work, a lot of effort has been put into the standardization of the soil classification system, thus ensuring a common basis. The development, state of the art and further development of both classification and taxation systems initiated and carried out by the ASSS will be shown.

  16. Ecology of black pineleaf scale (Homoptera: Diaspididae)

    1973-10-01

    The ecology of black pineleaf scale which occurs on several species of pine and Douglas fir causing defoliation, discoloration of foliage, and reduced growth is reviewed. All known outbreaks of this scale have been caused by reduction in the population of Prosphaltella parasitoid that normally keeps the scale populations at very low densities. Abnormal mortality of Prosphaltella has been found to be caused either by the presence of sorptive dusts or by drift of insecticides. High population densities of scale have been found mainly in areas of high dust fall resulting from industrial sources and roadways. No known causal relationships have been found to exist between atmospheric fluorides and the black pineleaf scale population density. Environmental improvement to conserve the Prosphaltella parasitoids appears to be the most effective control measure.

    Historical data show that outbreaks of the tree killing mountain pine beetle are often preceded by periods of drought. Global climate change impacts drought frequency and severity and is implicated in the range expansion of the mountain pine beetle into formerly unsuitable habitats. Its expanded range has recently reached the lodgepole × jack pine hybrid zone in central Alberta, Canada, which could act as a transition from its historical lodgepole pine host to a jack pine host present in the boreal forest. This field study tested the effects of water limitation on chemical defenses of mature trees against mountain pine beetle-associated microorganisms and on beetle brood success in lodgepole × jack pine hybrid trees. Tree chemical defenses as measured by monoterpene emission from tree boles and monoterpene concentration in needles were greater in trees that experienced water deficit compared to well-watered trees. Myrcene was identified as specific defensive compound, since it significantly increased upon inoculation with dead mountain pine beetles. Beetles reared in bolts from trees that experienced water deficit emerged with a higher fat content, demonstrating for the first time experimentally that drought conditions benefit mountain pine beetles. Further, our study demonstrated that volatile chemical emission from tree boles and phloem chemistry place the hybrid tree chemotype in-between lodgepole pine and jack pine, which might facilitate the host shift from lodgepole pine to jack pine.

    "Vorarlberger Bergkäse" (VB) is an Austrian artisanal hard cheese produced from raw cow's milk. The composition of its rind microbiota and the changes in the microbial communities during ripening have not previously been investigated. This study used 16S and 18S rRNA gene cloning and sequencing to characterize the bacterial and fungal communities of seven pooled cheese rind samples taken in seven different ripening cellars of three Austrian dairy facilities. A total of 408 clones for 16S and 322 clones for 18S rRNA gene libraries were used for taxonomic classification, revealing 39 bacterial and seven fungal operational taxonomic units (OTUs). Bacterial OTUs belonged to four different phyla. Most OTUs were affiliated to genera often found in cheese, including high numbers of coryneforms. The most abundant OTU from 16S rRNA gene libraries showed highest similarity to Halomonas. Young cheese rinds were dominated by Actinobacteria or Proteobacteria, particularly by Halomonas and Brevibacterium aurantiacum, while Staphyloccocus equorum was most abundant in old cheeses. The most abundant 18S rRNA OTU had highest similarity to the filamentous fungus Scopulariopsis brevicaulis. Pairwise correlation analyses revealed putative co-occurrences between a number of OTUs. It was possible to discriminate the different cheese rind microbiota at the community-level by facility affiliation and ripening time. This work provides insights into the microbial composition of VB cheese rinds and might allow the processing- and ripening conditions to be improved to enhance the quality of the product.

  19. Post-irradiation examination of HTR-fuel at the Austrian Research Centre Seibersdorf Ltd

    International Nuclear Information System (INIS)

    Austrian R and D activities in the HTR-field reach back almost to the beginning of this advanced reactor line. For more than 20 years post-irradiation examination (PIE) of HTR-fuel has been performed at the laboratories of the Austrian Research Centre Seibersdorf Ltd. (OEFZS) (formerly OESGAE) and a high degree of qualification has been achieved in the course of that time. Most of the PIE-work has been carried out by international cooperation on contract basis with the OECD-DRAGON-project and with KFA-Juelich (FRG). There has also been some collaboration with GA (USA), Belgonucleaire and others in the past. HTR-fuel elements contain the fissile and fertile materials in form of coated particles (CPs) which are embedded in a graphite matrix. Because of this special design it has been necessary from the very beginning of the PIE work up to now to develop new methods (i.e. fuel element disintegration methods, chlorine gas leach, single particle examination techniques...) as well as to adapt and improve already existing methods (i.e. gamma spectrometry, mass-spectrometry, optical methods...). The main interests on PIE-work at Seibersdorf are concentrated on particle performance, fission product distribution and the 'free' Uranium content (contamination and broken particles) of the fuel elements (fuel spheres or cylindrical compacts). A short compilation of the applied methods and of available instrumental facilities is given as follows: deconsolidation of fuel elements; equipment for electrochemical deconsolidation; examinations and measurements of graphite and electrolyte samples; examination of coated particles; single particle examinations

    Austrian dairy farming is characterised by predominant use of Simmental cows on small-scale farms. Our aim was to identify lameness risk factors related to housing and management in cubicle housed Austrian dairy cows. Furthermore, we used animal-based parameters (ABP) as integrated measures of cubicle quality and feeding management. The first author visited 30 farms in eastern Austria with 24-54 cows (mean=35) in the milking herd during winter housing period, and collected data on housing, management, behaviour, and lameness via direct observations and an interview (part of Welfare Quality project). Mean lameness prevalence was 31% (range 6-70%). Data were analysed using logistic regression with generalised estimating equations (GEE). The final model was based on 832 cows and included six risk variables, five ABP, and the significant confounders 'county' and 'lactation number'. Odds for lameness increased with decreasing lying comfort, except for cubicle width. The following lying-related factors were significant in the final model (odds ratios (OR) in brackets): mats/mattresses as opposed to deep bedded cubicle base (1.61), length of lying area (OR 186-191 vs. loafing area (0.57). Regarding metabolic parameters, cows with a body condition score >3.5 had at least 0.39 lower odds of being lame, while cows with suboptimal milk protein content (3.8%) had 1.37 times higher odds. Odds for lameness clearly increased with age (OR lactation > or =4 vs. 1=3.38). In sum, lying comfort and nutrition are key areas for lameness prevention on modern dairy farms in Austria with herd sizes above 30 cows. PMID:19409629

    The current epidemic of the mountain pine beetle (MPB), an indigenous pest of western North American pine, has resulted in significant losses of lodgepole pine. The leading edge has reached Alberta where forest composition shifts from lodgepole to jack pine through a hybrid zone. The susceptibility of jack pine to MPB is a major concern, but there has been no evidence of host-range expansion, in part due to the difficulty in distinguishing the parentals and their hybrids. We tested the utilit...

    In Sweden, the pine weevil causes damages for several hundreds of millions kronor annually. The discouraged use of insecticides has resulted in that other methods to prevent pine weevil feeding needs to be found. Antifeedants found in the pine weevil own feces is one such alternative. The source of the most active antifeedants in the feces is probably from bacterial or fungal lignin degrading symbionts in the pine weevil gut. The aim of the project was to analyze the pine weevil gut microbiot...

  3. Accumulation of cesium-137 and strontium-90 in ponderosa pine and monterey pine seedlings

    International Nuclear Information System (INIS)

    Because ponderosa pine Pinus ponderosa and Monterey pone (P. radiata D Don) have exceptionally fast growth rates and their abscised needles are not readily dispersed by wind, these species may be valuable for removing radioisotopes from contaminated soils. Ponderosa and Monterey pine seedlings were tested for their ability to accumulate 137Cs and 90Sr-characteristic radioisotopes of nuclear fallout-from contaminated soil. Seedlings were grown for 3 mo in 165 cm3 sphagnum peat moss/perlite (1:1 V/V) in a growth chamber. In Exp. 1, seedling accumulation of 137Cs and 90Sr after 1 mo of exposure was measured. In Exp. 2, seedling accumulation of the radioisotopes during different-length exposures was measured. Seedling accumulation of 137CS and 90Sr at different concentrations of the radioisotopes in the growth medium was measured in Exp. 3. Ponderosa pine accumulated 6.3% of the 137Cs and I.5% of the 90Sr present in the growth medium after 1 mo; Monterey pine accumulated 8.3% of the 137Cs and 4.5% of the 90Sr. Accumulation of 137Cs and 90Sr by both coniferous species was curvilinearly related to duration of exposure. Accumulation of 137Cs and 90Sr by both species increased with increasing concentration in the growth medium and correlated curvilinearly with radioisotope concentration in the growth medium. Large areas throughout the world are contaminated with 137Cs and 90Sr as a result of nuclear weapons testing or atomic reactor accidents. The ability of trees to sequester and store 137Cs and 90Sr introduces the possibility of using reforestation to remediate contaminated soils

    Soil contamination by silver nanoparticles (AgNP) is of potential environmental concern but little work has been carried out on the effect of such contamination on ectomycorrhizal fungi (EMF). EMF are essential to forest ecosystem functions as they are known to enhance growth of trees by nutrient transfer. In this study, soil was experimentally contaminated with AgNP (0, 350 and 790 mg Ag/kg) and planted with Bishop pine seedlings. The effect of AgNP was subsequently measured, assessing variation in pine growth and ectomycorrhizal diversity associated with the root system. After only 1 month, the highest AgNP level had significantly reduced the root length of pine seedlings, which in turn had a small effect on above ground plant biomass. However, after 4 months growth, both AgNP levels utilised had significantly reduced both pine root and shoot biomass. For example, even the lower levels of AgNP (350 mg Ag/kg) soil, reduced fresh root biomass by approximately 57 %. The root systems of the plants grown in AgNP-contaminated soils lacked the lateral and fine root development seen in the control plants (no AgNP). Although, only five different genera of EMF were found on roots of the control plants, only one genus Laccaria was found on roots of plants grown in soil containing 350 mg AgNP/kg. At the higher levels of AgNP contamination, no EMF were observed. Furthermore, extractable silver was found in soils containing AgNP, indicating potential dissolution of silver ions (Ag+) from the solid AgNP.

    Polychlorinated naphthalenes (PCNs) are a group of 75 compounds, which have been commercially produced and used in a wide range of industrial applications for the sake of their specific chemical properties. They are recognized as good electrical insulators and also as water and flame resistant materials. Technical PCNs formulations were mainly used as capacitor dielectrics, engine oil additives, electroplating stop-off compounds, in wire insulations and as paper, wood and fabric preservatives. Moreover, they have been formed during production of PCBs formulations. Although recently most countries have stopped synthesis of PCNs, they still are widely distributed in the environment. Nowadays the principal sources of these compounds are municipal solid wastes incineration, metallurgical and chloro-alkali processes. In last years PCNs concentrations in the environment have posed the cynosure of big group of scientists in the whole world. The relatively high concentrations are regarded as an environmental problem. Because they are persistent, toxic and lipophilic they might be bioaccumulated in living organisms and generate the danger for animals and humans. It is essentially to monitor their levels in air, regional transport, as well as estimate specific sources. It is possible by using as a biomonitors pine tree needles. These trees are considered as the very suitable passive indicators for monitoring of PCNs concentrations in the troposphere. This is because the surface wax layer of the needles poses an ability to absorb these lipophilic compounds from the surrounding air. In the current study pine needles were employed as biomonitors of PCNs concentrations in the ambient air of Poland. This country with its past history of production and use of different applications including these compounds, as well as with its location in the centre of Europe, presents the interesting region to these researches.

    There are concerns that large-scale stand mortality due to mountain pine beetle (MPB) could greatly reduce natural regeneration of serotinous Rocky Mountain (RM) lodgepole pine (Pinus contorta var. latifolia) because the closed cones are held in place without the fire cue for cone opening. We selected 20 stands (five stands each of live [control], 3 years since MPB [3-yr-MPB], 6 years since MPB [6-yr-MPB], and 9 years since MPB [9-yr-MPB] mortality) in north central British Columbia, Canada. The goal was to determine partial loss of serotiny due to fall of crown-stored cones via breakage of branches and in situ opening of canopy cones throughout the 2008 and 2009 growing seasons. We also quantified seed release by the opening of forest-floor cones, loss of seed from rodent predation, and cone burial. Trees killed by MPB three years earlier dropped approximately 3.5 times more cones via branch breakage compared to live stands. After six years, MPB-killed stands had released 45% of their canopy seed bank through cone opening, cone fall due to breakage, and squirrel predation. Further losses of canopy seed banks are expected with time since we found 9-yr-MPB stands had 38% more open canopy cones. This was countered by the development of a modest forest-floor seed bank (6% of the original canopy seed bank) from burial of cones; this seed bank may be ecologically important if a fire or anthropogenic disturbance reexposes these cones. If adequate levels of regeneration are to occur, disturbances to create seedbeds must occur shortly after tree mortality, before the seed banks are lost. Our findings also suggest that the sustained seed rain (over at least nine years) after MPB outbreak may be beneficial for population growth of ground-foraging vertebrates. Our study adds insight to the seed ecology of serotinous pines under a potentially continental-wide insect outbreak, threatening vast forests adapted to regeneration after fire.

    The aim of this investigation was to find relationships between the structure of the dissolved lignin and the combustion properties (pyrolysis time, char burning time, and swelling) of softwood and hardwood kraft black liquors. In this conjunction, pine and birch chips, as well as their two mixtures (the mass ratios of pine chips to birch chips were 80:20 and 60:40), were delignified by conventional kraft pulping. In each cook series, a liquor sample was withdrawn at certain time intervals to obtain liquor samples with different chemical composition. The black liquors obtained were analyzed with respect to the content of lignin and `lignin monomers`, but also the molecular-mass distribution and the mass average molecular mass of lignin were made. In addition, the dissolved lignin was characterized by NMR spectroscopy and elemental analysis. Further data on the chemical structures of lignin in black liquors were obtained by identifying various degradation products formed from this material during oxidative (CuO oxidation) and pyrolytic treatments. Several correlations between the `structural parameters` of the dissolved lignin and the combustion properties of black liquor were found. These correlations were significant especially in the case of pine cook. The results revealed many findings which are, together with the earlier data, useful for a better understanding of the thermochemical behavior of different kraft black liquors during combustion in a recovery furnace.

    In order to establish a new method for making cellulose and lignin from Masson pine, a high boiling solvent (HBS) pulping process with an aqueous solvent of 1,4-butanediol was investigated. Masson pine chips were pulped with a 70%-90% aqueous solution of 1,4-butanediol containing a small amount of a catalyst at 200-220 ℃ for 60-180 min. HBS Masson pine cellulose is suitable for making paper. Water-insoluble HBS lignin was separated from the liquor reaction mixture by water precipitation. The recovered high boiling solvent (RHBS) is able to be recycled as a pulping solvent, indicating that the HBS method is a pulping process of Masson pine which is energy saving, resources saving and pollution free. HBS lignin has a better chemical reactivity and a lower ash content than lignin sulfonate.

    2015-07-01

    Full Text Available Knowledge of a carnivore’s foraging behaviour is essential to understand its ecology. The pine marten Martes martes is commonly defined as an opportunistic generalist predator since its diet in Europe includes mammals, fruits, birds and invertebrates. Based on faecal analyses, we evaluated spring feeding habits and trophic niche breadth of the pine marten in a Mediterranean landscape on the island of Sardinia (Central Italy. The most important source of food for the pine marten was small mammals (mainly Apodemus sylvaticus, Mus musculus and Eliomys quercinus, accounting for 52% of the percent mean volume. Important secondary foods were invertebrates (mainly beetles and insect larvae and birds (almost exclusively passerines, whereas large mammals, lagomorphs, reptiles and fruits made little contribution to the diet. The diet composition and the Levins’ index value suggest that the pine marten in Sardinia behaves as a facultative specialist predator, with a specialization towards small mammals.

  3. Localized spatial and temporal attack dynamics of the mountain pine beetle in lodgepole pine. Forest Service research paper

    Energy Technology Data Exchange (ETDEWEB)

    Bentz, B.J.; Powell, J.A.; Logan, J.A.

    1996-12-01

    Colonization of a host tree by the mountain pine beetle (Dendroctonus ponderosae) involves chemical communication that enables a massive aggregation of beetles on a single resource, thereby ensuring host death and subsequent beetle population survival. Beetle populations have evolved a mechanism for termination of colonization on a lodgepole pine tree at optimal beetle densities, with a concomitant switch of attacks to nearby trees. Observations of the daily spatial and temporal attack process of mountain pine beetles (nonepidemic) attacking lodgepole pine suggest that beetles switch attacks to a new host tree before the original focus tree is fully colonized, and that verbenone, an antiaggregating pheromone, may be acting within a tree rather than between trees.

    Full Text Available Teaching is a mirror that reveals how a nation defines and limits its identity in history, taking its landmarks at cultural level. The situation of education in Bukovina during the Austrian occupation was precarious, especially in the presence of the Romanian language in schools. In that sense, the Romanians of Bukovina fought against the preponderance of German language, imposed by the Austrian occupation and against the pressure exerted by the Ukrainians to impose their mother tongue in educational institutions. If the quality of the teaching of the first schools remained at a fairly low level, the time has come when, following the Western model, Bukovina raised the level of its institutions.

    Full Text Available In Austria, Technical Colleges are those educational institutions that train and educate the skilled technical staff required by the Austrian labour market and the universities. These colleges have contributed a lot to Austria’s economic success and every year about 8,000 young engineers leave the technical schools to form a powerful work and study force. Therefore, it is particularly important that the education they receive meets the requirements of prospective employers and that innovative developments are anticipated. As a consequence, the Austrian Technical Colleges have developed curricula that rely on learning outcomes and competence-based results. This new orientation towards skills, knowledge and competences shall be achieved through learning objectives that precisely describe the education chosen. How these standards have been designed, matched with the curricula, and implemented at the Colleges will be described in this paper.

Besides these positive effects, health risks of open-air activities are mainly related to unprotected sun light exposure-associated acute and chronic skin hazards. Thus, we conducted a cross-sectional, representative telephone survey among Austrian residents to study the association of perceived CN level with sun-exposure knowledge, tanning habits, and sun protective behaviour. In total, 1,500 study subjects (50.5% females) participated in this questionnaire survey. Although knowledge about tanning and motives to tan were similar among genders, females performed more photoprotective measures and were more connected to nature (all p habits of Austrian residents. The findings suggest to integrate hitherto neglected gender-specific Public (Skin) Health promotion when counselling on the manifold health advantages of outdoor activities. PMID:24448634

    2014-02-01

    Full Text Available The mountain pine beetle, Dendroctonus ponderosae, is a significant pest of lodgepole pine in British Columbia (BC, where it has recently reached an unprecedented outbreak level. Although it is native to western North America, the beetle can now be viewed as a native invasive because for the first time in recorded history it has begun to reproduce in native jack pine stands within the North American boreal forest. The ability of jack pine trees to defend themselves against mass attack and their suitability for brood success will play a major role in the success of this insect in a putatively new geographic range and host. Lodgepole and jack pine were sampled along a transect extending from the beetle’s historic range (central BC to the newly invaded area east of the Rocky Mountains in north-central Alberta (AB in Canada for constitutive phloem resin terpene levels. In addition, two populations of lodgepole pine (BC and one population of jack pine (AB were sampled for levels of induced phloem terpenes. Phloem resin terpenes were identified and quantified using gas chromatography. Significant differences were found in constitutive levels of terpenes between the two species of pine. Constitutive α-pinene levels – a precursor in the biosynthesis of components of the aggregation and antiaggregation pheromones of mountain pine beetle – were significantly higher in jack pine. However, lower constitutive levels of compounds known to be toxic to bark beetles, e.g., 3-carene, in jack pine suggests that this species could be poorly defended. Differences in wounding-induced responses for phloem accumulation of five major terpenes were found between the two populations of lodgepole pine and between lodgepole and jack pine. The mountain pine beetle will face a different constitutive and induced phloem resin terpene environment when locating and colonizing jack pine in its new geographic range, and this may play a significant role in the ability of the

  20. Long-term benefits to the growth of ponderosa pines from controlling southwestern pine tip moth (Lepidoptera: Tortricidae) and weeds.

    Wagner, Michael R; Chen, Zhong

    2004-12-01

    The southwestern pine tip moth, Rhyacionia neomexicana (Dyar) (Lepidoptera: Tortricidae), is a native forest pest that attacks seedlings and saplings of ponderosa pine, Pinus ponderosa Dougl. ex Laws, in the southwestern United States. Repeated attacks can cause severe deformation of host trees and significant long-term growth loss. Alternatively, effective control of R. neomexicana, vegetative competition, or both in young pine plantations may increase survival and growth of trees for many years after treatments are applied. We test the null hypothesis that 4 yr of R. neomexicana and weed control with insecticide, weeding, and insecticide plus weeding would not have any residual effect on survival and growth of trees in ponderosa pine plantation in northern Arizona 14 yr post-treatment, when the trees were 18 yr old. Both insecticide and weeding treatment increased tree growth and reduced the incidence of southwestern pine tip moth damage compared with the control. However, weeding alone also significantly increased tree survival, whereas insecticide alone did not. The insecticide plus weeding treatment had the greatest tree growth and survival, and the lowest rate of tip moth damage. Based on these results, we rejected our null hypothesis and concluded that there were detectable increases in the survival and growth of ponderosa pines 14 yr after treatments applied to control R. neomexicana and weeds.

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

  2. Modeling glacier beds in the Austrian Alps: How many lakes will form in future?

    Science.gov (United States)

    Koehler, Dominik; Geilhausen, Martin; Linsbauer, Andreas

    2014-05-01

    Glacial retreat exposes landscapes with relief characteristics greatly differing from the former ice covered surfaces. If glacial retreat exposes natural basins capable of forming proglacial lakes, then the downstream hydrologic and geomorphic systems in such catchments will be significantly altered due to discharge modifications, sediment trapping, decoupling effects and long term sediment storage (e.g. Geilhausen et al. 2013). Further implications are related to hydropower management, tourism and natural hazards. Consequently, sound knowledge of present day glacier beds ("proglacial zones of tomorrow") and in particular the total number, locations and characteristics of overdeepenings are of importance. For Austria, however, this important information about significant future changes of high alpine regions is yet missing. An interdisciplinary research project is currently in preparation to close this gap. This paper presents results of a pilot study. We used a novel GIS-based approach (GlabTop, cf. Linsbauer et al. 2012) to compute approximate glacier beds in the Austrian Alps. GlabTop ('Glacier bed Topography') is based on an empirical relation between average basal shear stress and elevation range of individual glaciers and makes use of digital elevation models (DEM), glacier outlines and branch lines (i.e. a set of lines covering all important glacier branches). DEMs and glacier outlines were derived from the Austrian glacier inventory (1998) and branch lines were manually digitized. The inventory includes 911 glaciers of which 876 (96%) were considered and 35 were excluded due to size restrictions ( 0.01 km²) with the potential of forming proglacial lakes when glacier retreat reveals the bed. The total area and volume of all overdeepenings is approx. 10 km² and 236 Mio m³ respectively and 33 lakes will be larger than 1 km³. A total glacier volume of 16 ± 5 km³ with an average ice thickness of 36 ± 11 m was calculated for 1998. Comparisons with

    The Austrian UVB monitoring network is operational since 1997. Nine detectors for measuring erythemally weighted solar UV irradiance are distributed over Austria in order to cover the main populated areas as well as different levels of altitude. The detectors are calibrated to indicate the UV-Index, the internationally agreed unit for erythemally weighted solar UV irradiance. Calibration is carried out in the laboratory for determination of spectral sensitivity of each detector, and under the sun for absolute comparison with a well-calibrated, double-monochromator spectro-radiometer. For the conversion from detector-weighted units to erythemally weighted units a lookup table is used, which is calculated using a radiative transfer model and which reflects the dependence of the conversion on the solar zenith angle and total ozone content of the atmosphere. The uncertainty of the calibration is about ±7%, dominated by the uncertainty of the calibration lamp for the spectro-radiometer (±4%). The long-term stability of this type of detectors has been found to be not satisfactory. Therefore, routinely every year all detectors are completely re-calibrated. Variations of the calibration factors up to ±10% are found. Thus, during routine operation, several measures take place for quality control. The measured data are compared to results of model calculations with a radiative transfer model, where clear sky and an aerosol-free atmosphere are assumed. At each site, the UV data are also compared with data from a co-located pyrano-meter measuring total solar irradiance. These two radiation quantities are well correlated, especially on clear days and when the ozone content is taken into account. If suspicious measurements are found for one detector in the network, a well-calibrated travelling reference detector of the same type is set up side-by-side, allowing the identification of relative differences of ∼3%. If necessary, a recalibration is carried out. As the main aim

    Recreational sun exposure accounts for a large number of acute and chronic dermatological diseases, including skin cancer. This study aimed at estimating the one-year prevalence of sun exposure and skin health-associated knowledge and attitudes among Austrian citizens. The population-based UVSkinRisk survey investigated a representative sample of Austrian adults using a structured questionnaire. In total, 1500 study subjects (median age 33.0 years, 50.5% females) participated in this questionnaire survey. Among study participants, prevalence of sun exposure was 47%, with slightly higher rates in males (48%) compared to females (46%). Younger age, lower professional category, darker skin type, motives to tan, sunbed use, sunburn, and outdoor sport activity increased the odds for prevalent sun exposure. This is the first population-based study evaluating the prevailing sun exposure and recreational habits influencing skin health among Austrian citizens. Despite public media campaigns educating on the harmful effects of sunlight exposure, we found a high prevalence of self-reported sunlight exposure. The results suggest that multifaceted socio-cultural characteristics stimulate recreational sun exposure and tanning habits. Communicating individualized Public (Skin) Health messages might be the key to prevent photo-induced skin health hazards in light-skinned populations. The practical and theoretical implications of these findings are discussed. PMID:26797627

  5. Rise, use and treatment of works in Austria. Compiled for the Austrian Federal Waste Management Plan 2001

    International Nuclear Information System (INIS)

    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)

    Soil contamination by silver nanoparticles (AgNP) is of potential environmental concern but little work has been carried out on the effect of such contamination on ectomycorrhizal fungi (EMF). EMF are essential to forest ecosystem functions as they are known to enhance growth of trees by nutrient transfer. In this study, soil was experimentally contaminated with AgNP (0, 350 and 790 mg Ag/kg) and planted with Bishop pine seedlings. The effect of AgNP was subsequently measured, assessing varia...

  8. Joint Annual Meeting of the Swiss Physical Society and the Austrian Physical Society together with the Swiss and Austrian Societies for Astronomy and Astrophysics

    International Nuclear Information System (INIS)

    The annual meeting 2011 which took place at the EPFL in Lausanne on June 15-17, was organized jointly with the Austrian Physical Society OePG, and both national societies of Astronomy and Astrophysics (SSAA and OeGAA), as a successful follow-up of the Innsbruck meeting in 2009. With 10 parallel sessions, more than 470 submitted abstracts and nearly 650 participants, one can claim that our goal to make our meeting more attractive to the physics community was achieved. The commercial exhibition with the presence of 22 companies was the largest ever organized by our society. The 10 plenary talks of the three morning sessions covered a broad spectrum of modern physics from condensed matter physics (Bose Einstein condensation of photons, Quantum cascade lasers, 2D electron gas between insulators, stretchable electronics, superconductivity) to large scale physics (LHC at CERN, the ITER project at Cadarache) without forgetting Earth and planetary science (high velocity impacts in the solar system) and simulation of the universe by computational astrophysics. The presence of our Austrian colleagues had also an impact on the parallel sessions. For example a session 'Surfaces, Interfaces and Thin films' was organized as a complement to the Condensed Matter one. To our great pleasure a session on 'Theory and Simulations', composed of the three suptopics 'Large Scale Computing', 'Theoretical Physics Today' and 'Computational Astrophysics' was part of the program. Another novelty was the session on Geophysics which covered topics like geophysical fluid dynamics, Earth and planetary magnetism or even the safety assessment of deep geological nuclear waste depositories. On the first evening, a public lecture given in the Polydome by M. Marthaler and colleagues on the topic 'Le Cervin est-il africain? Une histoire de la derive des oceans et continents' unravelled the mystery of the origin of our most famous Swiss mountain, the Matterhorn. For the second time a successful series of

  9. Regional geology of the Pine Creek Geosyncline

    International Nuclear Information System (INIS)

    The Pine Creek Geosyncline comprises about 14km of chronostratigraphic mainly pelitic and psammitic Lower Proterozoic sediments with interlayered tuff units, resting on granitic late Archaean complexes exposed as three small domes. Sedimentation took place in one basin, and most stratigraphic units are represented throughout the basin. The sediments were regionally deformed and metamorphosed at 1800Ma. Tightly folded greenschist facies strata in the centre grade into isoclinally deformed amphibolite facies metamorphics in the west and northeast. Pre and post-orogenic continental tholeiites, and post-orogenic granite diapirs intrude the Lower Proterozoic metasediments, and the granites are surrounded by hornfels zones up to 10km wide in the greenschist facies terrane. Cover rocks of Carpentarian (Middle Proterozoic) and younger ages rest on all these rocks unconformably and conceal the original basin margins. The Lower Proterozoic metasediments are mainly pelites (about 75 percent) which are commonly carbonaceous, lesser psammites and carbonates (about 10 percent each), and minor rudites (about 5 percent). Volcanic rocks make up about 10 percent of the total sequence. The environment of deposition ranges from shallow-marine to supratidal and fluviatile for most of the sequence, and to flysch in the topmost part. Poor exposure and deep weathering over much of the area hampers correlation of rock units; the correlation preferred by the authors is presented, and possible alternatives are discussed. Regional geological observations pertinent to uranium ore genesis are described. (author)

    Tyrosinases are related to the enzymatic browning of plants and attract the major scientific interest for the prevention of it. Three tyrosinase isozymes (P{sub 1}, P{sub 2} and P{sub 3}) from pine needles were purified to homogeneity and characterized the factors that affect their activities. The L-ascorbic acid and {beta}-mercaptoethanol notably inhibited the enzymatic activities of the three isozymes. The sodium diethyldithiocarbamate was a competitive inhibitor of isozymes with the K{sub i} values of P{sub 1}(0.30 mM), P{sub 2}(0.015 mM) and P{sub 3}(0.019 mM), respectively. Their enzyme activities were however, increased by the addition of most metal ions. The optimum pH for the three isozymes was 9.0{approx}9.5 and the optimum temperatures ranged from 55 to 60{sup o} C using L-DOPA as substrate. 15 refs., 3 figs., 2 tabs.

    L-band HV multiple-incidence-angle aircraft synthetic aperture radar (SAR) data were analyzed in relation to average stand biomass, basal area, and tree height for 55 slash pine plantations located in northern Florida. This information was used to develop a system of equations to predict average stand biomass as a function of L-band (24.5-cm) radar backscatter. The system of equations developed in this study using three-stage least-squares and combinatorial screening accounted for 97 percent of the variability observed in average stand biomass per hectare. When applied to an independent data set, the biomass equations had an average bias of less than 1 percent with a standard error of approximately 3 percent. These results indicate that future Shuttle Imaging Radar Systems (e.g., SIR-C, which will have cross-polarized radar sensors) should be able to obtain better estimates of forest biomass than were obtained with previous satellite radar missions, which utilized only HH-polarized SAR data.

    2011-01-01

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

  13. Natural radionuclides in Austrian mineral water and their sequential measurement by fast methods

    International Nuclear Information System (INIS)

    Ten samples of Austrian mineral water were investigated with regard to the natural radionuclides 228Ra, 226Ra, 210Pb, 210Po, 238U and 234U. The radium isotopes as well as 210Pb were measured by liquid scintillation counting (LSC) after separation on a membrane loaded with element-selective particles (EmporeTM Radium Disks) and 210Po was determined by α-spectroscopy after spontaneous deposition onto a copper planchette. Uranium was determined by ICP-MS as well as by α-spectroscopy after ion separation and microprecipitation with NdF3. From the measured activity concentrations the committed effective doses for adults and babies were calculated and compared to the total indicative dose of 0.1 mSv/a given in the EC Drinking Water Directive as a maximum dose. The dominant portion of the committed effective dose was due to the radium isotopes; the dose from 228Ra in most samples clearly exceeded the dose from 226Ra

    The Austrian portion of the Bohemian Massif is a Precambrian terrane composed mostly of highly metamorphosed rocks intruded by a series of granitoids that are petrographically similar. Rocks are exposed poorly and the subtle variations in rock type are difficult to map in the field. A detailed geochemical survey of stream sediments in this region has been conducted and included as part of the Geochemischer Atlas der Republik O??sterreich, and the variations in stream sediment composition may help refine the geological interpretation. In an earlier study, multivariate analysis of variance (MANOVA) was applied to the stream-sediment data in order to minimize unwanted sampling variation and emphasize relationships between stream sediments and rock types in sample catchment areas. The estimated coefficients were used successfully to correct for the sampling effects throughout most of the region, but also introduced an overcorrection in some areas that seems to result from consistent but subtle differences in composition of specific rock types. By expanding the model to include an additional factor reflecting the presence of a major tectonic unit, the Rohrbach block, the overcorrection is removed. This iterative process simultaneously refines both the geochemical map by removing extraneous variation and the geological map by suggesting a more detailed classification of rock types. ?? 1995 International Association for Mathematical Geology.

  15. The liberalization of the European energy market from the perspective of the Austrian regional power company

    International Nuclear Information System (INIS)

    This dissertation addresses the liberalization of the European energy sector from an Austrian perspective, emphasizing its effect on a regional power company (KELAG). The energy market's changing conditions are creating new opportunities for consumers that allow them to optimize their ability to fulfill their power requirements. Decentralized solutions are now just as viable for large industrial customers as the ability to have all energy supplied through the utility network. In addition, partnerships with independent power producers (IPP's) or cooperation between the large customers in energy production can be considered. From a regional perspective, the central management concept of KELAG is the answer to an altered market situation, since this concept created tremendous potential for streamlining the management of energy production and operation of the network. The liberalization of the energy market for large industrial customers in Carinthia's electricity sector was preceded by a series of important decisions. The Verbundgesellschaft combine their generating facilities. In the future the power plants of Draukraft in Carinthia will be supervised and controlled remotely from KELAG's central control unit in Klagenfurt, as a result of which the central control unit becomes the primary energy control for Carinthia.

    Numerical simulations were carried out with the weather research and forecasting model to study the influence of different land-use datasets for two Austrian regions, the high-alpine Inn Valley area and the hilly Vienna Basin area. The three land-use datasets used were USGS, MODIS and a reclassified European dataset based on the CORINE CLC06 data. Simulations covered an episode in July 2007 applying a resolution of 0.8 km. Results were compared with surface observation data, radiosoundings, and satellite data. It was found that land-use both in the original CLC06 and the version where it had been reclassified to USGS classes for use in WRF was significantly more realistic than the built-in land-use datasets (USGS and MODIS). Synoptic processes during the episode considered were reproduced well by all simulations, where CLC06 and MODIS improved the model performance in both regions in terms of the surface temperatures and other meteorological parameters.

    The aim of this study was to conduct a multitrait 2-step approach applied to yield deviations and deregressed breeding values to get genetic parameters of functional longevity, clinical mastitis, early fertility disorders, cystic ovaries, and milk fever of Austrian Fleckvieh cattle. An approximate multitrait approach allows the combination of information from pseudo-phenotypes derived from different statistical models in routine genetic evaluation, which cannot be estimated easily in a full multitrait model. A total of 66,890 Fleckvieh cows were included in this study. For estimating genetic parameters, a simple linear animal model with year of birth as a fixed effect and animal as a random genetic effect was fitted. The joint analysis of yield deviations and deregressed breeding values was feasible. As expected, heritabilities were low, ranging from 0.03 (early fertility disorders) to 0.15 (functional longevity). Genetic correlations between functional longevity and clinical mastitis, early fertility disorders, cystic ovaries, and milk fever were 0.63, 0.29, 0.20, and 0.20, respectively. Within direct health traits genetic correlations were between 0.14 and 0.45. Results suggest that selecting for more robust disease-resistant cows would imply an improvement of functional longevity.

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

  19. Teleconsultation 2001 - working group report of the Austrian Roentgen Society (OeRG)

    International Nuclear Information System (INIS)

    In 1997, the working group ''Teleconsultation'' of the Austrian Roentgen Society (OeRG) has performed a first survey about the status of teleradiological applications in Austria. Now, in 2001, a second survey was performed in order to adapt the OeRG's approach in this field to the most actual needs. Most of the 38 teleradiological projects in Austria already working or shortly before inauguration are aiming at an improvement of the medical service in favour of our patients (expert consultation, image transfer to doctors requesting radiological examinations, clinical case discussion). However, a small but not unimportant fraction of teleradiology projects in Austria (11%) is performed for replacement of radiologists on duty, therefore for reasons mainly directed to minimising costs for the hospital administration. Other purposes of teleradiology projects, like quality assurance and medical education have even lost their small importance the 1997 survey already has shown. This paper discusses the professional implications from the results of the 2001 survey and the legal framework for the application of telecommunication in diagnostic radiology. The most important goal of all professional activities in radiology is the well-being of our patients, based on the immediacy of the medical profession in accordance with the ''physician law''.

    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.

    Temperature is suggested to determine the upper limit of tree life. Therefore, future climate warming may be of importance for tree distribution within the European Alps, where low temperatures limit carbon metabolism.We focused on the effects of air and soil temperature on net photosynthesis (P(n)) of Pinus cembra an evergreen climax species of the timberline ecotone of the Central Austrian Alps. Light response and temperature response curves were estimated along an altitudinal gradient ranging from the forest limit up to the krummholz limit in both summer and fall.In general, P(n) was significantly lower in fall as compared to summer. Nevertheless, independent from season mean P(n) values tended to increase with elevation and were positively correlated with root zone temperatures. The specific leaf area by contrast declined with increasing elevation. Furthermore, the temperature optimum of net photosynthesis declined with increasing elevation and was positively correlated with the mean maximum air temperature of the 10 days prior the date of measurement.Thus, our findings appear to reflect a long-term adaptation of the photosynthetic apparatus of Pinus cembra to the general temperature conditions with respect to elevation combined with a short term acclimation to the prevailing temperature regime.

    Constantly changing climate, the further development of geostatistical interpolation methods and the availability of a higher resolved digital elevation model gave reason for updating the most frequently demanded climate maps out of the Austrian digital climate atlas (ÖKLIM) from 1961-1990 to 1971-2000. The resulting 19 grids concern 30-year-means of air temperature (annual, January, July means) and derived indices (ice days, frost days, freeze-thaw days, summer days, hot days, heating degree days), precipitation (annual, winter half-year, summer half-year sums) and derived indices (days with precipitation, percentage of solid precipitation), snow (sum of fresh-fallen snow, snow cover duration, maximum snow depth) and sunshine (January, July absolute sunshine duration) parameters. For application in all branches of geosciences (e.g. climate variability and modelling, hydrology, biogeography, natural hazards) as well as for planning in all kinds of contexts (e.g. agriculture, tourism, generation of renewable energy, climate change adaption) such digital grids of standard climate information are greatly demanded and likely to gain even more importance in the near future. Data preparation was carried out with large effort. In order to avoid adverse border effects and to guarantee an equal state of quality across all parts of the country, the study region was extended beyond the national borders and stations from all neighbouring countries were requested. The final data collection includes between 319 (percentage of solid precipitation) and 1,399 (annual precipitation sum) records from eleven national and foreign institutes. To achieve a station density as high as possible, data gaps of up to five or ten years were filled considering the same parameter at reference stations or a related parameter station-wise. According to the climate parameter, different geostatistical interpolation methods were applied. Multiple regressions against elevation, longitude, latitude and

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

    Full Text Available The aim of this study was to evaluate the level of inbreeding of meat performance tested herd book sheep in Austria and to evaluate the effect of individual inbreeding on growth and CT (computer tomography scan carcass traits. Performance data (13,614 records, five breeds: Merinoland, Suff olk, Texel, German Blackheaded Meat sheep, Jura were collected in the years 2000-2010. The traits analysed were live weight and average daily gain, as well as traits of body frame, back fat and eye muscle area, all measured on live animals with CT. Inbreeding coefficients (F were calculated with the soft ware PEDIG. F was nested within breed and tested in a mixed model using ASReml. Levels of inbreeding were low with O F of 1.5-3.1%. Only few traits were significantly affected by inbreeding. Both positive and negative effects were found. The effects were small, most oft en nonlinear and vary across breeds. Inbreeding and its effects on performance traits do not seem to be an issue in Austrian meat sheep populations at the moment. However, monitoring and further analyses are recommended.

    Ten samples of Austrian mineral water were investigated with regard to the natural radionuclides (228)Ra, (226)Ra, (210)Pb, (210)Po, (238)U and (234)U. The radium isotopes as well as (210)Pb were measured by liquid scintillation counting (LSC) after separation on a membrane loaded with element-selective particles (Empore Radium Disks) and (210)Po was determined by alpha-spectroscopy after spontaneous deposition onto a copper planchette. Uranium was determined by ICP-MS as well as by alpha-spectroscopy after ion separation and microprecipitation with NdF(3). From the measured activity concentrations the committed effective doses for adults and babies were calculated and compared to the total indicative dose of 0.1 mSv/a given in the EC Drinking Water Directive as a maximum dose. The dominant portion of the committed effective dose was due to the radium isotopes; the dose from (228)Ra in most samples clearly exceeded the dose from (226)Ra. PMID:18243442

  7. Estimate of the radiation exposure of the Austrian population due to the reactor accident Chernobyl

    International Nuclear Information System (INIS)

    One year after the reactor accident at Chernobyl an estimate as objective as possible of the average exposure of the Austrian population in the first year after the accident is attempted. Besides the exposure path of external radiation from the cloud and ground and the exposure due to inhalation the most important path, that caused by ingestion of radionuclides via contaminated food is described in detail. The contribution of various food stuffs to the ingestion dose is described. The effective equivalent dose estimated from the average activity concentration and the average consumption per year of the respective food stuffs amounts to 0.46 mSv for the adult and 0.40 mSv for the one year old infant in the first year. In addition to the dose due to external radiation and inhalation this results in a total dose of 0.53 mSv for the adult and 0.47 mSv for the infant. The ingestion dose estimated in this way poses possibly a substantial overestimation since the whole body activity content measured in numerous whole body counter measurements results in only one third of the dose estimated from food activity concentrations. 18 refs., 11 figs.

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

    The Pine Bluff Arsenal (PBA) near Pine Bluff, Arkansas, is one of eight continental United States (CONUS) Army installations where lethal unitary chemical agents and munitions are stored and where destruction of agents and munitions is proposed under the Chemical Stockpile Disposal Program (CSDP). The chemical agent inventory at PBA consists of approximately 12%, by weight, of the total US stockpile. The destruction of the stockpile is necessary to eliminate the risk to the public from continued storage and to dispose of obsolete and leaking munitions. In 1988 the US Army issued a Final Programmatic Environmental Impact Statement (FPEIS) for the CSDP that identified on-site disposal of agents and munitions as the environmentally preferred alternative (i.e., the alternative with the least potential to cause significant adverse impacts). The purpose of this report is to examine the proposed implementation of on-site disposal at PBA in light of more recent and more detailed data than those on which the FPEIS is based. New population data were used to compute fatalities using the same computation methods and values for all other parameters as in the FPEIS. Results indicate that all alternatives are indistinguishable when the potential health impacts to the PBA community are considered. However, risks from on-site disposal are in all cases equal to or less than risks from other alternatives. Furthermore, no unique resources with the potential to prevent or delay implementation of on-site disposal at PBA have been identified.

  11. Collins pine/BCI biomass to ethanol project

    International Nuclear Information System (INIS)

    California has abundant biomass resources and a growing transportation fuels market. These two facts have helped to create an opportunity for biomass to ethanol projects within the state. One such project under development is the Collins Pine/BCI Project. Collins Pine Company and BC International (BCI) have teamed up to develop a forest biomass to ethanol facility to be collocated with Collins Pine's 12 MW, biomass-fueled electric generator in Chester, California. The Collins Pine Company (headquartered in Portland, Oregon) is an environmentally progressive lumber company that has owned and operated timberlands near Chester, California since the turn of the century. Collins manages 100,000 acres of timberland in the immediate area of the project. BCI (Dedham, Massachusetts) holds an exclusive license to a new, patented biotechnological process to convert lignocellulosic materials into ethanol and other specially chemicals with significant cost savings and environmental benefits. The project has received a California Energy Commission PIER program award to continue the developmental work done in the Quincy Library Group's Northeastern California Ethanol Manufacturing Feasibility Study (November 1997). This paper provides (1) a brief overview of the biomass and transportation fuels market in California; (2) the current status of the Collins Pine/BCI biomass ethanol project; and (3) future prospects and hurdles for the project to overcome.

    The pine weevil Hylobius abietis (L.) is a severe pest of conifer seedlings in reforested areas of Europe and Asia. To identify minimally toxic and ecologically sustainable compounds for protecting newly planted seedlings, we evaluated the volatile metabolites produced by microbes isolated from H. abietis feces and frass. Female weevils deposit feces and chew bark at oviposition sites, presumably thus protecting eggs from feeding conspecifics. We hypothesize that microbes present in feces/frass are responsible for producing compounds that deter weevils. Here, we describe the isolation of a fungus from feces and frass of H. abietis and the biological activity of its volatile metabolites. The fungus was identified by morphological and molecular methods as Penicillium expansum Link ex. Thom. It was cultured on sterilized H. abietis frass medium in glass flasks, and volatiles were collected by SPME and analyzed by GC-MS. The major volatiles of the fungus were styrene and 3-methylanisole. The nutrient conditions for maximum production of styrene and 3-methylanisole were examined. Large quantities of styrene were produced when the fungus was cultured on grated pine bark with yeast extract. In a multi-choice arena test, styrene significantly reduced male and female pine weevils' attraction to cut pieces of Scots pine twigs, whereas 3-methylanisole only reduced male weevil attraction to pine twigs. These studies suggest that metabolites produced by microbes may be useful as compounds for controlling insects, and could serve as sustainable alternatives to synthetic insecticides. PMID:23297108

    The pine wood nematode, Bursaphelenchus xylophilus, is the causal agent of pine wilt disease that has devastated pine forests in Asia. Parasitic nematodes are known to have evolved antioxidant stress responses that defend against host plant defenses. In this study, the infestation of whitebark pine, Pinus bungean, with B. xylophilus led to a significant increase in plant hydrogen peroxide (H2O2) and salicylic acid levels. Correspondingly, the expression of an antioxidative enzyme, 2-Cysteine ...

    Pine plantations near Perth, Western Australia have provided an important food source for endangered Carnaby's Cockatoos (Calyptorhynchus latirostris) since the 1940s. Plans to harvest these plantations without re-planting will remove this food source by 2031 or earlier. To assess the impact of pine removal, we studied the ecological association between Carnaby's Cockatoos and pine using behavioural, nutritional, and phenological data. Pine plantations provided high densities of seed (158,025...

  15. Using pheromones to protect heat-injured lodgepole pine from mountain pine beetle infestation. Forest Service research note

    Amman, G.D.; Ryan, K.C.

    1994-01-01

    The bark beetle antiaggregative pheromones, verbenone and ipsdienol, were tested in protecting heat-injured lodgepole pine (Pinus contorta Dougl. ex Loud.) from mountain pine beetle (Dendroctonus ponderosae) infestation in the Sawtooth National Recreation Area in central Idaho. Peat moss was placed around 70 percent of the basal circumference of lodgepole pines. When the peat moss was ignited, it simulated the smoldering of natural duff, generating temperatures that killed the cambium. The four treatments tested were uninjured tree, heat-injured tree, heat-injured tree treated with verbenone, and heat-injured tree treated with verbenone plus ipsdienol. Treatments were replicated 20 times. Mountain pine beetles were attracted into treatment blocks by placing mountain pine beetle tree baits on metal posts 3 to 5 meters from treated trees. Fisher's Extract Test showed that treatment and beetle infestation were not independent (P < 0.015). Check treatments contained more unattacked and mass-attacked trees, whereas pheromone treatments contained more unsuccessfully attacked trees.

  16. Tritium concentrations in pine needle, litter and soil samples

    International Nuclear Information System (INIS)

    Samples of pine needle, litter and soil samples collected in/around Akita City and Rokkasho Village in 1989 were analyzed for both free water 3H (FWT) and organically-bound 3H (OBT). The FWT concentrations decrease in the order, litter or soil>pine needle. FWT concentrations in soil depend on the moisture content, and tend to increase with decreasing soil moisture content. This relationship is consistent with the observation that FWT in the soil increases with oxidation of atmospheric tritiated hydrogen gas (HT) and decreases with rainwater dilution. The OBT concentrations increase in the order pine needle3H concentrations may be reflected as high OBT concentrations in soils of the present. (author)

    1992-01-01

    Bright P-band radar returns from red pine forests have been observed on synthetic aperture radar (SAR) images in Bangor, Maine. A plot of red pine trees was selected for the characterization and modeling to understand the cause of the high P-band returns. The red pine stand under study consisted of mature trees. Diameter at breast height (DBH) measurements were made to determine stand density as a function of tree diameter. Soil moisture and bulk density measurements were taken along with ground rough surface profiles. Detailed biomass measurements of the needles, shoots, branches, and trunks were also taken. These site statistics have been used in a distorted Born approximation model of the forest. Computations indicate that the direct-reflected or the double-bounce contributions from the ground are responsible for the high observed P-band returns for HH polarization.

    2010-07-01

    Performance of longleaf (Pinus palustris Mill.) and loblolly pine (P. taeda L.) were compared 15–19 years after outplanting on 10 different sites in the sandhillsof South Carolina. The study was established from 1988 to 1992 with bareroot seedlings artificially inoculated with Pisolithus tinctorius (Pt) or naturally inoculated with mycorrhizae in the nursery. A containerized longleaf pine treatment with and without Pt inoculation was added to two sites in 1992. Effects of the Pt nursery treatment were mixed, with a decrease in survival of bareroot longleaf pine on two sites and an increase in survival on another site. The containerized longleaf pine treatment substantially increased survival, which led to greater volume compared with bareroot longleaf pine. Loblolly pine yielded more volume than longleaf pine on all sites but one, where survival was negatively affected by fire. Depth of sandy surface horizon affected mean annual height growth of both loblolly and longleaf pine. Height growth per year decreased with an increase in sand depth for both species. Multiple regression analysis of volume growth(ft3/ac per year) for both species indicated a strong relationship to depth of sandy soil and survival. After 15–19 years, loblolly pine has been more productive than longleaf pine, although longleaf pine productivity may be equal to or greater than that of loblolly pine on the soils with the deepest sandy surface layers over longer rotations.

    Over the past decade and a half Western North America has experienced a mountain pine beetle (Dendroctonus ponderosae) outbreak on a scale not previously recorded. Millions of hectares of lodgepole pine (Pinus contorta) in high elevation forests have been devastated. Although bark beetles are an important part of the endemic disturbance and regeneration regime in this region, the current unprecedented level of tree mortality will have a significant impact on resources and light availability to surviving trees. We established a decade-long chronosequence of mountain pine beetle disturbance, in a lodgepole stand, composed of three age classes: recent, intermediate, and longest (approximately 2-4, 5-7, 8-10 years respectively) time since initial infestation, as well as a control group. The focus of the study was a healthy tree and it's area of influence (1m radius from the bole), each located in a cluster of the respective chronosequence classes. In the 2011 growing season we have looked at rates of photosynthesis, and water potentials for the healthy trees, as well as soil respiration flux and gravimetric moisture in their areas of influence. We are also in the process of analyzing soil extractable dissolved organic carbon and nitrogen, ammonium, nitrate, and inorganic phosphorus, and plan to take hemispherical photographs and analyze tree-ring stable isotopes to determine if there is any reallocation of soil water use by the trees. Our data shows that photosynthetic rates in the youngest infestation class increase 10 percent over the control group and then falls well bellow the control by the oldest class. The mineral soil gravimetric moisture drastically increases between the control and the recent class and then maintains a consistently higher level through the remaining classes. In contrast, moisture in the organic soil significantly declines between the control and recent class before rebounding to pre-infestation levels in the two older classes. Soil

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

  3. Mitochondrial Haplogroup T Is Associated with Obesity in Austrian Juveniles and Adults.

    Directory of Open Access Journals (Sweden)

    Sabine Ebner

    Full Text Available Recent publications have reported contradictory data regarding mitochondrial DNA (mtDNA variation and its association with body mass index. The aim of the present study was to compare the frequencies of mtDNA haplogroups as well as control region (CR polymorphisms of obese juveniles (n = 248 and obese adults (n = 1003 versus normal weight controls (njuvenile = 266, nadults = 595 in a well-defined, ethnically homogenous, age-matched comparative cohort of Austrian Caucasians.Using SNP analysis and DNA sequencing, we identified the nine major European mitochondrial haplogroups and CR polymorphisms. Of these, only the T haplogroup frequency was increased in the juvenile obese cohort versus the control subjects [11.7% in obese vs. 6.4% in controls], although statistical significance was lost after adjustment for sex and age. Similar data were observed in a local adult cohort, in which haplogroup T was found at a significantly higher frequency in the overweight and obese subjects than in the normal weight group [9.7% vs. 6.2%, p = 0.012, adjusted for sex and age]. When all obese subjects were considered together, the difference in the frequency of haplogroup T was even more clearly seen [10.1% vs. 6.3%, p = 0.002, OR (95% CI 1.71 (1.2-2.4, adjusted for sex and age]. The frequencies of the T haplogroup-linked CR polymorphisms C16294T and the C16296T were found to be elevated in both the juvenile and the adult obese cohort compared to the controls. Nevertheless, no mtDNA haplogroup or CR polymorphism was robustly associated with any of several investigated metabolic and cardiovascular parameters (e.g., blood pressure, blood glucose concentration, triglycerides, cholesterol in all obese subjects.By investigation of this large ethnically and geographically homogenous cohort of Middle European Caucasians, only mtDNA haplogroup T was identified as an obesity risk factor.

    2014-08-01

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

    2015-04-01

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

  6. The Austrian radiation monitoring network ARAD – best practice and added value

    2015-10-01

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

    2016-05-01

    Forest ecosystems of the Pacific Northwest of the USA are changing as a result of climate change. Specifically, rise of global temperatures, decline of winter precipitation, earlier loss of snowpack, and increased summer drought are altering the range of Pinus contorta. Simultaneously, flux in environmental conditions within the historic P. contorta range may facilitate the encroachment of P. ponderosa into P. contorta territory. Furthermore, successful pine species migration may be constrained by the distribution or co-migration of ectomycorrhizal fungi (EMF). Knowledge of the linkages among soil fungal diversity, community structure, and environmental factors is critical to understanding the organization and stability of pine ecosystems. The objectives of this study were to establish a foundational knowledge of the EMF communities of P. ponderosa and P. contorta in the Deschutes National Forest, OR, USA, and to examine soil characteristics associated with community composition. We examined EMF root tips of P. ponderosa and P. contorta in soil cores and conducted soil chemistry analysis for P. ponderosa cores. Results indicate that Cenococcum geophilum, Rhizopogon salebrosus, and Inocybe flocculosa were dominant in both P. contorta and P. ponderosa soil cores. Rhizopogon spp. were ubiquitous in P. ponderosa cores. There was no significant difference in the species composition of EMF communities of P. ponderosa and P. contorta. Ordination analysis of P. ponderosa soils suggested that soil pH, plant-available phosphorus (Bray), total phosphorus (P), carbon (C), mineralizable nitrogen (N), ammonium (NH4), and nitrate (NO3) are driving EMF community composition in P. ponderosa stands. We found a significant linear relationship between EMF species richness and mineralizable N. In conclusion, P. ponderosa and P. contorta, within the Deschutes National Forest, share the same dominant EMF species, which implies that P. ponderosa may be able to successfully establish

    2004-01-01

    Nonuniform black strings in the two-brane system are investigated using the effective action approach. It is shown that the radion acts as a nontrivial hair of the black strings. From the brane point of view, the black string appears as the deformed dilatonic black hole which becomes a dilatonic black hole in the single brane limit and reduces to the Reissner-Nordström black hole in the close limit of two-branes. The stability of solutions is demonstrated using catastrophe theory. From the bulk point of view, the black strings are proved to be nonuniform. Nevertheless, the zeroth law of black hole thermodynamics still holds.

    Temperature measurements were made to better understand the role of microclimate on mountain pine beetle, Dendroctonus pondersae Hopkins (Coleoptera:Scolytidae), activity as a result of thinning lodgepole pine stands. Sampling was done over 61 days on the north slope of the Unita Mountain Range in Northeastern Utah. Principal components analysis was applied to all temperature variables. Most of the variation was attributed to two variables, coolest part of the night and hottest part of the day. The thinned stand was approximately 1 deg. C warmer than the unthinned stand.

    The surface energy exchange of 12m high Scots pine plantation at Hartheim, Germany, was measured with a variety of methods during a 11-day period of fine weather in mid-May 1992. Net radiation and rate of thermal storage were measured with conventional net radiometers, soil heat flux discs and temperature-based storage models. The turbulent fluxes discussed in this report were obtained with an interchanging Bowen ratio energy budget system (BREB, at 14 m), two one-propeller eddy correlation systems (OPEC systems 1 and 2 at 17m), a 1-dimensional sonic eddy correlation system (SEC system 3) at 15 m, all on one “low” tower, and a 3-dimensional sonic eddy correlation system (SEC system 22) at 22 m on the “high” tower that was about 46 m distant. All systems measured sensible and latent heat (H and LE) directly, except for OPEC systems 1 and 2 which estimated LE as a residual term in the surface energy balance. Closure of turbulent fluxes from the two SEC systems was around 80% for daytime and 30% for night, with closure of 1-dimensional SEC system 3 exceeding that of 3-dimensional SEC system 22. The night measurements of turbulent fluxes contained considerable uncertainty, especially with the BREB system where measured gradients often yielded erroneous fluxes due to problems inherent in the method (i.e., computational instability as Bowen's ratio approaches -1). Also, both eddy correlation system designs (OPEC and SEC) appeared to underestimate |H| during stable conditions at night. In addition, both sonic systems (1- and 3-dimensional) underestimated |LE| during stable conditions. The underestimate of |H| at night generated residual estimates of OPEC LE containing a “phantom dew” error that erroneously decreased daily LE totals by about 10 percent. These special night problems are circumvented here by comparing results for daytime periods only, rather than for full days. To summarize, turbulent fluxes on the low tower from OPEC system 2 and the adjacent

  11. Evaluation of recommendations on limits of exposure to ultraviolet radiation on the basis of data from the Austrian population

    International Nuclear Information System (INIS)

    For the application of solaria at present the following international recommendations on limits of exposure exist, which differ strongly: 1. IRPA/INIRC (1991): 30 MED/a (i.e. 7.5 kJ/a). 2. IEC 335-2-27 (1978, 1989): 25 kJ/m2/a for each region of the body, that is 100 MED/a. On the basis of our data from the Austrian population we give an evaluation of these recommendations for the entire population. This evaluation shows that 100 MED/a is much too high, it seduces rather to use solaria than to restrict their application

    Full Text Available Social media marketing has become a powerful tool of interaction with stakeholders. An increasing number of companies are using social media platforms to initiate active interaction and communication with current and prospective customers. Within this study, certain content and contact features, as well as social media activities of companies of the Austrian food and beverage industry were evaluated. Empirical findings concerning the threats, risks, and opportunities connected with the application of social media are presented. The results imply that social media applications are innovative alternatives for customer relationship management. However, more knowledge on how to properly use social media marketing seems to be necessary.

  4. Soil water regime under homogeneous eucalyptus and pine forests

    International Nuclear Information System (INIS)

    Measurement of precipitation and monthly soil water content during two consecutive years, in 6-year old plantations of eucalypt and pine, and also in an open plot containing natural herbaceous vegetation, were used to compare the soil water regime of these vegetation covers. Precipitation was measured in the open plot with a recording and a non-recording rain gage. Soil water was assessed by the neutron scattering technique to a depth of 1,80 meters. Results indicate that there was, in general, water available in the soil over the entire period of study in all three vegetation conditions. The annual range of soil water in eucalypt, pine, and in natural herbaceous vegetation was essentially similar. The analysis of the average soil water regime showed that the soil under herbaceous vegetation was, generally, more umid than the soil under eucalypt and pine during the period of soil water recharge (September through February); during the period of soil water depletion, the opposite was true. Collectively, the results permit the conclusion that there were no adverse effects on the soil water regime which could be ascribed to reflorestation with eucalypt or pine, as compared with that observed for the natural herbaceous vegetation

  5. Skin Reactions to Pine Processionary Caterpillar Thaumetopoea pityocampa Schiff

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Pine caterpillar, Thaumetopoea pityocampa Schiff, is a phyto- and xylophagous lepidopteran, responsible for the delay in the growth or the death of various types of pines. Besides nature damage, pine caterpillar causes dermatological reactions in humans by contact with its irritating larvae hairs. Although the dermatitis occurs among outdoor professionals, it is primarily extraprofessional. Contamination generally occurs in pinewoods, rarely in cities. Means of contamination comprise direct contact with the nest or the processional caterpillar and indirect contact with air dispersed hairs. The dermatitis is generally observed in late spring and particularly from April to June, among campers and tourers. The eruption has its onset 1–12 hours after contact with the hairs and presents with intense and continuous itching. Morphologically, it is strophulus-like and consists of papulous, excoriated, and pinkish lesions on an oedematous base. Diagnosis is usually straightforward. The pathogenetic mechanism of the affection is mechanical, pharmacological, and allergic in nature. Besides skin, T. pityocampa Schiff can involve the eyes and rarely the airways. Despite the considerable damages to humans and nature, pine caterpillar infestation is an underestimated problem; medical literature lists few studies, and often relevant information is referred to local media and popular wisdom.

    Full Text Available The renewable pine needles was used as an adsorbent to remove phosphorus from aqueous solutions. Using batch experiments, pine needles pretreated with alkali-isopropanol (AI failed to effectively remove phosphorus, while pine needles modified with lanthanum hydroxide (LH showed relatively high removal efficiency. LH pine needles were effective at a wide pH ranges, with the highest removal efficiency reaching approximately 85% at a pH of 3. The removal efficiency was kept above 65% using 10 mg/L phosphorus solutions at desired pH values. There was no apparent significant competitive behavior between co-existing anions of sulfate, nitrate, and chloride (SO4(2-, NO3(- and Cl(-; however, CO3(2- exhibited increased interfering behavior as concentrations increased. An intraparticle diffusion model showed that the adsorption process occurred in three phases, suggesting that a boundary layer adsorption phenomena slightly affected the adsorption process, and that intraparticle diffusion was dominant. The adsorption process was thermodynamically unfavorable and non-spontaneous; temperature increases improved phosphorus removal. Total organic carbon (TOC assays indicated that chemical modification reduced the release of soluble organic compounds from 135.6 mg/L to 7.76 mg/L. This new information about adsorption performances provides valuable information, and can inform future technological applications designed to remove phosphorus from aqueous solutions.

    Full Text Available Normal 0 14 false false false MicrosoftInternetExplorer4 Normal 0 14 false false false MicrosoftInternetExplorer4 In Italy the palebark pine (Pinus leucodermis Antoine forms natural populations present in Calabria and Lucania at the borderline between the two regions on calcareous soils and litho-soils. The surface range is about 5700 hectares, distributed in four natural groups of vegetation, two Apennine areas (Alpi, Spina -Zàccana, Pollino and two coastal areas (Palanuda-Pellegrino, Montéa. In the mountain areas the species becomes exclusive and shows resistance to climate harshness at high elevation, ability to colonise ecologically difficult sites, aptitude and specific reliability to artificial spreading. The experimental plan, carried out without any repetition because technically unfeasible in the area, estimated three input variables: plastic bag-grown S2F2 and bare-rooted seedlings S2T2, inter-distance on the terrace (0.5m, 1m, 1.5m, elevation a.s.l. (1400m, 1550m, 1700m. 4 yrs old seedlings, one half plastic bag-grown and one half bare-rooted, were transplanted in autumn in each site on 24 terraces (4x3x2 handmade in summer. Each sampled area was made up of four adjacent terraces for an overall length of 184 m. Transplanting operations were completed in December and an enclosure was set up to protect the plantation from grazing. As a whole, the experimental areas was shaped as a rectangle. Additional terraces, carried out in the lower part, were planted with bare-rooted Austrian pine and Silver fir seedlings at an inter-distance of 1m and provided the direct comparison with the same thesis of palebark pine. Maintenance practices were undertaken in June and in July of the first and second year to eliminate weeds and shrubs along the terraces. The mensurational surveys were carried out in 1982-1983-1987-1994-2007-2009. The quite complete mortality of Austrian pine and Silver fir transplants in 1983-84 made impossible any further

    Numerous studies have quantified the amount of plastic litter in aquatic ecosystems and tried to assess its impacts and threats. This reflects a rising awareness of plastic as an environmental problem. As a next logical step, identifying and regulating the sources must be in the focus of scientific efforts. We report on a spillage of industrial microplastic (IMP) from a production plant situated at an Austrian Danube tributary. This is the first identified point source of IMP litter in freshwater systems. However, due to generous thresholds established by the Austrian government substantial amounts of IMP are legally introduced into running waters. PMID:25734504

    This study presents biomass functions applicable to Scots pine (Pinus sylvestris L.) on Arenosols in Lithuania, and exemplifies the potential biomass removal from Scots pine stands during thinnings. Scots pine is the most common tree species on Arenosols in Lithuania. Stands of ages 10, 20, 40, 50 and 65 years were chosen for the biomass study. We sampled 5 Scots pine trees per plot (in total 25 trees) that were stratified according to the basal area. The sampling was performed in April 2003, before the vegetative period. The following components of each tree were sampled for the above-ground biomass measurements: (1) 5 stem discs, (2) 1 branch with needles from each whorl and (3) 1 dead branch per tree. Observed biomasses of above-ground components were examined using a non-linear regression model, using stem diameter (D), tree height (H) and D{sup 2}H as independent variables. For stemwood biomass, the best approximation was D{sup 2}H. However, D{sup 2}H was not the best parameter for crown biomass because it does not allow evaluation of the opposite effects of diameter and height on crown biomass. The calculations at stand level showed that crown biomass changed insignificantly with the increase in stand age. However, the total stand biomass increased with age due to the growth of the stem. The removal of all logging residues from the Scots pine stand over a 100-year rotation could increase extraction of forest fuel by 15-20% compared with conventional harvesting. (author)

  11. Siberian Pine Decline and Mortality in Southern Siberian Mountains

    The causes and resulting spatial patterns of Siberian pine mortality in eastern Kuznetzky Alatau Mountains, Siberia were analyzed based on satellite (Landsat, MODIS) and dendrochronology data. Climate variables studied included temperature, precipitation and Standardized Precipitation-Evapotranspiration Index (SPEI) drought index. Landsat data analysis showed that stand mortality was first detected in the year 2006 at an elevation of 650 m, and extended up to 900 m by the year 2012. Mortality was accompanied by a decrease in MODIS derived vegetation index (EVI).. The area of dead stands and the upper mortality line were correlated with increased drought. The uphill margin of mortality was limited by elevational precipitation gradients. Dead stands (i.e., >75% tree mortality) were located mainly on southern slopes. With respect to slope, mortality was observed within a 7 deg - 20 deg range with greatest mortality occurring on convex terrain. Tree radial incrementmeasurements correlate and were synchronous with SPEI (r sq = 0.37, r(sub s) = 80). Increasing synchrony between tree ring growth and SPEI indicates that drought has reduced the ecological niche of Siberian pine. The results also showed the primary role of drought stress on Siberian pine mortality. A secondary role may be played by bark beetles and root fungi attacks. The observed Siberian pine mortality is part of a broader phenomenon of "dark needle conifers" (DNC, i.e., Siberian pine, fir and spruce) decline and mortality in European Russia, Siberia, and the Russian Far East. All locations of DNC decline coincided with areas of observed drought increase. The results obtained are one of the first observations of drought-induced decline and mortality of DNC at the southern border of boreal forests. Meanwhile if model projections of increased aridity are correct DNC, within the southern part of its range may be replaced by drought-resistant Pinus silvestris and Larix sibirica.

  12. Derivation of GNSS derived station velocities for a surface deformation model in the Austrian region

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

    The year to year variability and trends of animal phenological phases (honey bee, cockchafer, 3 butterfly species, swallow and cuckoo) of the Austrian phenological observational network were related to each other and to mean monthly temperatures over the time period 1951-1998. Insect phases were well correlated with each other (r{sup 2} = 0.4 to 0.6) and with temperature (r{sup 2} = 0.25 to 0.55), whereas both bird phases were only well correlated with each other (r{sup 2} = 0.57), but showed low common variance values with temperature and with other animal phases. The slope of the temperature-pheno regression, also termed as temperature sensitivity of the phenological phase, was high in the case of the insect phases (-3 to -5 days/ C), but low in the cases of both bird phases (about -1 days/ C). All animal phenological time series showed a trend towards later occurrence dates. The trends of the bird phases were even significant (p<0.1). There was a marked discrepancy between the trends of all animal phenological and temperature time series, especially between the insects and temperature: the mean temperature time series of February, March and April with the highest common variance with the insect phases showed a strongly increasing trend (0.027 C/year), whereas the first appearance dates of the insects tended to occur later (0.06 to 0.15 days/year). Both bird phases correlated weakly with the mean April temperature (r{sup 2} about 0.1). The temperature trend of April was 0.0003 C/year, whereas the trend of the bird phases was 0.2 days/year for the cuckoo and 0.25 days/year for the swallow. From these observations we conclude that a strong temperature sensitivity of the phenological phase based on the year to year variability (in days/ C) does not necessarily result in corresponding trends of temperature and phenological phase. A strong trend of non-atmospheric factors such as population density influencing the animal phases is suspected. Factors other than local

It is shown that LASAT is able to simulate the position of the plume and that the modelled and the measured concentration values do not deviate more than 30 %. This study reveals that LASAT can be applied to tunnel portal emissions. The model simulations for both the Ehrentalerbergtunnel and Kaisermühlentunnel meet the requirements specified in the Austrian design guideline RVS 9.263 “Ventilation Systems - Pollutant burden at portals”.

  16. Use of the TRIGA Reactor by the Radiochemistry Group of the Atominstitute of the Austrian Universities

    International Nuclear Information System (INIS)

    The Radiochemistry Group of the Atominstitute of the Austrian Universities uses the TRIGA Mark II Reactor mainly for neutron activation analysis. Transport of samples to and from the irradiation positions in the reactor is performed by fast pneumatic transfer systems (transfer time 20 msec and 300 msec) and slow conventional transport facilities. Gamma-spectrometric instrumentation equipped with loss free counting systems is used to handle the high count rates up to 500 000 counts/sec. During the last years neutron activation analysis was applied to investigate environmental samples (soil, dust, incineration ash), geological samples (rocks, sediments, fossils, volcanic gases), biological materials (lichens, mushrooms and other plant materials, human diet, biological reference materials), raw materials (phosphate, coal) and archaeological materials (ancient glass). Lichen analysis was used for environmental monitoring. The content of some of the trace elements can be correlated with industrial activities, like manganese content with steel industry, the occurrence of vanadium and nickel with oil firing plants and stainless steel industry, selenium is found in lichen near coal firing plants. The amount of chlorine and sodium indicates the application of salt for road treatment during winter time, aluminum, scandium and hafnium content depends on the amount of dust in the environment. A further environmental application of neutron activation analysis is the determination of trace elements in volcanic gases. The halogens, arsenic, antimony, selenium, tellurium and mercury were determined and their daily output was calculated. The distribution of trace elements in fossils of known age gives us a geochemical key to condition and development of the paleo-environment. For this purpose we determined rare earth elements in 250 million years old microfossils (conodonts). Neutron activation analysis served also for some non scientific but nevertheless useful purposes: Organic

A diffusion chamber, developed at Karlsruhe, FRG, was used to construct a passive radon detector. It consists of a plastic beaker covered with a glass fibre filter. It is shielded by a cover which has openings on the side so that air can diffuse through and on the top there is a mounted thermoluminescent detector card. The TLD dosimeter was used to determine beta and gamma radiation levels. A polycarbonate foil was placed at the bottom of the diffusion chamber which served as a detector for the alphas emitted by radon daughters. The dosimeters were exposed for a period of three months. The mean concentration of radon in all rooms in dwelling houses in Austria were clearly higher in winter than in summer time. This was interpreted as the effect of reduced ventilation rates in winter time. This effect of ventilation on radon concentration is more significant in living and sleeping rooms than in the cellar. Compared to all rooms in a dwelling house the level of radon concentration was distinctly higher in the cellar. Higher values of radon concentration were found in famous radon spa of Gastein and in the Waldviertel and in a landscape near the Czechoslovakian border. In Vienna a mean value for radon concentration in the living and sleeping rooms was found to be 47 bq/m3 which corresponds to an estimated effective dose equivalent to the lung of 10.7 mSv per annum. The whole body effective dose equivalent was estimated to be 1.27 mSv per annum. These estimations were based on the radon equilibrium factor of 0.5. The exposure to radon at such concentration is estimated to cause 3-4% incidence of excess lung cancer in Vienna within the next 20 years. The value of 47 bq/m3 of radon in Vienna and its surrounding areas corresponds well with the mean values in Switzerland and Germany, but it is lower than those found in Great Britain, Canada, Sweden

    The European Union has defined environmental quality standards (EQSs) for surface waters for priority substances and several other pollutants. Furthermore national EQSs for several chemicals are valid in Austria. The study investigated the occurrence of these compounds in municipal wastewater treatment plant (WWTP) effluents. In a first screening of 15 WWTPs relevant substances were identified, which subsequently were monitored in 9 WWTPs over 1 year (every 2 months). Out of 77 substances or groups of substances (including more than 90 substances) 13 were identified as potentially relevant in respect to water pollution and subjected to the monitoring, whereas most other compounds were detected in concentrations far below the respective EQS for surface waters and therefore not further considered. The preselected 13 compounds for monitoring were cadmium (Cd), nickel (Ni), copper (Cu), selenium (Se), zinc (Zn), diuron, polybrominated diphenyl ethers (PBDEs), di(ethyl-hydroxyl)phthalate (DEHP), tributyltin compounds (TBT), nonylphenoles (NP), adsorbable organic halogens (AOX) and the complexing agents ethylenediaminetetraacetic acid (EDTA) as well as nitrilotriacetic acid (NTA). In the effluents of WWTPs the concentrations of the priority substances Cd, NP, TBT and diuron frequently exceeded the respective EQS, whereas the concentrations for DEHP and Ni were below the respective EQS. The effluent concentrations for AOX, EDTA, NTA, Cu, Se and Zn frequently are in the range or above the Austrian EQS for surface waters. Besides diuron and EDTA all compounds are removed at least partially during wastewater treatment and for most substances the removal via the excess sludge is the major removal pathway. For the 13 compounds which were monitored in WWTP effluents population equivalent specific discharges were calculated. Since for many compounds no or only few information is available, these population equivalent specific discharges can be used to assess emissions from

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

    Full Text Available Connectedness to nature (CN influences motivation to have contact with outdoor natural environments. Spending leisure time in natural environments is beneficial for human health and well-being. Besides these positive effects, health risks of open-air activities are mainly related to unprotected sun light exposure-associated acute and chronic skin hazards. Thus, we conducted a cross-sectional, representative telephone survey among Austrian residents to study the association of perceived CN level with sun-exposure knowledge, tanning habits, and sun protective behaviour. In total, 1,500 study subjects (50.5% females participated in this questionnaire survey. Although knowledge about tanning and motives to tan were similar among genders, females performed more photoprotective measures and were more connected to nature (all p < 0.001 compared to males. Older age and outdoor sport were significant gender-independent predictor variables influencing perceived CN level. Additionally, level of education was relevant in male CN, whereas non-smoking and higher knowledge were predictive of female CN. This survey provides so far unreported empirical data on the relationship between nature connectedness and skin health-relevant recreational habits of Austrian residents. The findings suggest to integrate hitherto neglected gender-specific Public (Skin Health promotion when counselling on the manifold health advantages of outdoor activities.

    The occurrence and prevalence of pine wilt disease cause huge losses to Japan, China, and South Korea in East Asia, and have received concerns from many countries. By the methods of field observation and meteorological data analysis, this paper studied the characteristics of the occurrence and prevalence of pine wilt disease and their relations to the meteorological disaster events. In Japan, China and South Korea, the meteorological extreme events of persistent summer drought and strong typhoon could trigger the occurrence of pine wilt. In extremely dry and hot environment, pine trees often appeared energy metabolism imbalance and entire tree wilt. However, in the years with lower temperature and more rainfall, less or nearly no pine wilt event occurred. It was suggested that before the attack by pine wood nematode and its vectors, the vigor of the pines had already declined, and thus, pine wilt disease could be confined in the areas often hit by summer drought and strong typhoon events. In the areas with suitable natural environment characterized by less summer drought and strong typhoon events and no improperly enlarged pine planting, there would be little possibility of widespread occurrence of pine wilt disease.

    Rates of monoterpene emissions from Scots pine (Pinus sylvestris) and Norwegian spruce (Picea abies) have been measured at four sites in Sweden with a dynamic flow chamber technique. Forest floor emissions have been made in the pine forest with the static chamber technique. Sampling was done with Tenax TA and analysis and detection by GC and ion trap detection. The compounds Δ3-carene and α-pinene were the predominant terpenes emitted from the crown and floor of the Scots pine forest. Alpha-pinene was the main terpene emitted from Norwegian spruce at the sites in southern and central Sweden, while Δ3-carene was predominant at the northern site. The relative composition of the emission of both species underwent changes in early spring and fall. Emission rates, normalized to temperature, were seen to vary diurnally with a maximum at midday, and seasonally with maxima in early May and October, and a summer maximum in June-July. The possible dependence of the emission rate on needle growth rate and other plant-physiological processes is discussed. A higher emission rate and different relative composition of the emission was seen to occur when the vegetation was wet, as compared to dry vegetation. The emission from the pine forest floor was seen to have a composition different from that of the crown and a seasonality of the rate similar to that of the crown. The ground emission could not be explained by sources in the litter or ground vegetation alone, and it is suggested that the root system of the trees is also an emission source. The emission rate from the pine forest floor was of the order of 30% of the crown emission. The July rate of emission from the crown of Scots pine, normalized to 20°C and averaged over four sites in Sweden, was 0.8 ± 0.4 μg (gdw (grams dry weight) h)-1, and for Norwegian spruce, 0.5 ± 0.7 μg(gdw h)-1. It would seem that previous regional and global estimates of hydrocarbon fluxes to the atmosphere have used emission factors which are

    The Greater Yellowstone Ecosystem (GYE) has experienced changes in the distribution and availability of grizzly bear (Ursus arctos) food resources in recent decades. The decline of ungulates, fish, and whitebark pine seeds (Pinus albicaulis) has prompted questions regarding their ability to adapt. We examined body composition and diet of grizzly bears using bioelectrical impedance and stable isotopes to determine if 1) we can detect a change in diet quality associated with the decline in either ungulates or whitebark pine, and 2) the combined decline in ungulates, fish, and pine seeds resulted in a change in grizzly bear carrying capacity in the GYE. We contrasted body fat and mass in grizzly bears with a potential competitor, the American black bear (Ursus americanus), to address these questions. Grizzly bears assimilated more meat into their diet and were in better body condition than black bears throughout the study period, indicating the decline in ungulate resources did not affect grizzly bears more than black bears. We also found no difference in autumn fat levels in grizzly bears in years of good or poor pine seed production, and stable isotope analyses revealed this was primarily a function of switching to meat resources during poor seed-producing years. This dietary plasticity was consistent over the course of our study. We did not detect an overall downward trend in either body mass or the fraction of meat assimilated into the diet by grizzly bears over the past decade, but we did detect a downward trend in percent body fat in adult female grizzly bears after 2006. Whether this decline is an artifact of small sample size or due to the population reaching the ecological carrying capacity of the Yellowstone ecosystem warrants further investigation.

    Media weather reports as the main avenue of meteorological and climatological information to the general public have always been in the focus of critical investigation. Former research found that although weather reports are high-interest topics, the amount of information recalled by non-experts is rather low, and criticized this. A pilot study (Keul et al., 2009) by the Salzburg University in cooperation with ORF, the Austrian Broadcasting Corporation, used historic radio files on a fair-weather and a storm situation. It identified the importance of intelligible wording of the weather forecast messages for lay people. Without quality control, weather information can stimulate rumours, false comfort or false alarms. More qualitative and experimental research, also on TV weather, seems justified. This need for further research was addressed by a second and larger field experiment in the spring of 2010. The survey took place in Salzburg City, Austria, with a quota sample of about 90 lay persons. This time TV and radio weather reports were used and a more realistic listening and viewing situation was created by presenting the latest weather forecasts of the given day to the test persons in the very next hours after originally broadcasting them. It asked lay people what they find important in the weather reports and what they remember for their actual next-day use. Reports of a fairweather prognosis were compared with a warning condition. The weather media mix of the users was explored. A second part of the study was a questionnaire which tested the understanding of typical figures of speech used in weather forecasts or even meteorological terms, which might also be important for fully understanding the severe weather warnings. This leads to quantitative and qualitative analysis from which the most important and unexpected results are presented. Short presentation times (1.5 to 2 minutes) make Austrian radio and TV weather reports a narrow compromise between general

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

    Ice shelves around Antarctica are vulnerable to increase in ocean-driven melting, with the melt rate depending on ocean temperature and strength of sub-ice-shelf-cavity circulations. We present repeated measurements of velocity, temperature, salinity, turbulent kinetic energy dissipation rate and thermal variance dissipation rate beneath Pine Island Glacier Ice Shelf, collected by CTD, ADCP and turbulence sensors mounted on an Autonomous Underwater Vehicle (AUV). The turbulence quantities measured by the AUV outside the ice shelf are in good agreement with ship-based measurements. The highest rate of turbulent kinetic energy dissipation is found near the grounding line, while its temporal fluctuation over seabed ridge within the cavity corresponds to the tidal fluctuation predicted in the Pine Island Bay to the west. The highest thermal variance dissipation rate is found when the AUV was 0.5 m away from the ice, and the thermal variance dissipation generally increases with decreasing distance between the AUV and ice.

    Full Text Available Adsorption of a cationic phenothyazine dye methylene blueonto activated carbon prepared from pine cones was investigated with the variation in parameters of contact time, dye concentration and pH. The kinetic data were found to follow the pseudo-second-order kinetic modelclosely. The equilibrium data were best represented by the Langmuir isotherm with maximum adsorption capacity of 233.1 mg g-1. Adsorption was favored by using a higher solution pH. Textural analysis by nitrogen adsorption was used to determine specific surface area and pore structure of the obtained carbon. Boehm titrations revealed that carboxylic groups are present in the highest degree on the carbon surface. The results indicate that the presented method for activation of pine cones could yield activated carbon with significant porosity, developed surface reactivity and considerable adsorption affinity toward cationic dye methylene blue.

    Pine wood nematode (PWN), Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle is an important invasive alien species in forests of China and has become one of the most destructive forest diseases. In order to improve the resistance and resilience of pine forest ecosystems against B. xylophilus invasion and make the pine forest ecosystem more timely responsive to PWN invasion,we made some recommendations based on five years of intensive observations. We advocate a set of management measures with the theme "Prevention is priority, but integrated with curative techniques and ecological resilience" on the pine forest ecosystem invaded by B. xylophilus; details of accurate measures are proposed. The aim is to discover the underlying problems of present pine forest ecosystems and to take, correspondingly, administrative measures and strategies, which will encourage the pine forest ecosystem to develop in a benign way.

    The composition of Scots pine bark, its degradation, and the production of hydrolytic and ligninolytic enzymes were evaluated during 90 days of incubation with Phanerochaete velutina and Stropharia rugosoannulata. The aim was to evaluate if pine bark can be a suitable fungal substrate for bioremediation applications. The original pine bark contained 45% lignin, 25% cellulose, and 15% hemicellulose. Resin acids were the most predominant lipophilic extractives, followed by sitosterol and unsaturated fatty acids, such as linoleic and oleic acids. Both fungi degraded all main components of bark, specially cellulose (79% loss by P. velutina). During cultivation on pine bark, fungi also degraded sitosterol, produced malic acid, and oxidated unsaturated fatty acids. The most predominant enzymes produced by both fungi were cellulase and manganese peroxidase. The results indicate that Scots pine bark supports enzyme production and provides nutrients to fungi, thus pine bark may be suitable fungal substrate for bioremediation. PMID:20005699

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

  17. Pine Creek Ranch, FY 2001 annual report; ANNUAL

    International Nuclear Information System (INIS)

    Pine Creek Ranch was purchased in 1999 by the Confederated Tribes of Warm Springs using Bonneville Power Administration Fish and Wildlife Habitat Mitigation funds. The 25,000 acre property will be managed in perpetuity for the benefit of fish and wildlife habitat. Major issues include: (1) Restoring quality spawning and rearing habitat for stealhead. Streams are incised and fish passage barriers exist from culverts and possibly beaver dams. In addition to stealhead habitat, the Tribes are interested in overall riparian recovery in the John Day River system for wildlife habitat, watershed values and other values such as recreation. (2) Future grazing for specific management purposes. Past grazing practices undoubtedly contributed to current unacceptable conditions. The main stem of Pine Creek has already been enrolled in the CREP program administered by the USDA, Natural Resource Conservation Service in part because of the cost-share for vegetation restoration in a buffer portion of old fields and in part because of rental fees that will help the Tribes to pay the property taxes. Grazing is not allowed in the riparian buffer for the term of the contract. (3) Noxious weeds are a major concern. (4) Encroachment by western juniper throughout the watershed is a potential concern for the hydrology of the creek. Mark Berry, Habitat Manager, for the Pine Creek Ranch requested the Team to address the following objectives: (1) Introduce some of the field staff and others to Proper Functioning Condition (PFC) assessments and concepts. (2) Do a PFC assessment on approximately 10 miles of Pine Creek. (3) Offer management recommendations. (4) Provide guidelines for monitoring

    Understanding biological invasions patterns and mechanisms is highly needed for forecasting and managing these processes and their negative impacts. At small scales, ecological processes driving plant invasions are expected to produce a spatially explicit pattern driven by propagule pressure and local ground heterogeneity. Our aim was to determine the interplay between the intensity of seed rain, using distance to a mature plantation as a proxy, and microsite heterogeneity in the spreading of Pinus contorta in the treeless Patagonian steppe. Three one-hectare plots were located under different degrees of P. contorta invasion (Coyhaique Alto, 45° 30'S and 71° 42'W). We fitted three types of inhomogeneous Poisson models to each pine plot in an attempt for describing the observed pattern as accurately as possible: the "dispersal" models, "local ground heterogeneity" models, and "combined" models, using both types of covariates. To include the temporal axis in the invasion process, we analyzed both the pattern of young and old recruits and also of all recruits together. As hypothesized, the spatial patterns of recruited pines showed coarse scale heterogeneity. Early pine invasion spatial patterns in our Patagonian steppe site is not different from expectations of inhomogeneous Poisson processes taking into consideration a linear and negative dependency of pine recruit intensity on the distance to afforestations. Models including ground-cover predictors were able to describe the point pattern process only in a couple of cases but never better than dispersal models. This finding concurs with the idea that early invasions depend more on seed pressure than on the biotic and abiotic relationships seed and seedlings establish at the microsite scale. Our results show that without a timely and active management, P. contorta will invade the Patagonian steppe independently of the local ground-cover conditions. PMID:26843929

    Sequence capture is a flexible tool for generating reduced representation libraries, particularly in species with massive genomes. We used an exome capture approach to sequence the gene space of two of the dominant species in Canadian boreal and montane forests - interior spruce (Picea glauca x engelmanii) and lodgepole pine (Pinus contorta). Transcriptome data generated with RNA-seq were coupled with draft genome sequences to design baits corresponding to 26 824 genes from pine and 28 649 genes from spruce. A total of 579 samples for spruce and 631 samples for pine were included, as well as two pine congeners and six spruce congeners. More than 50% of targeted regions were sequenced at >10× depth in each species, while ~12% captured near-target regions within 500 bp of a bait position were sequenced to a depth >10×. Much of our read data arose from off-target regions, which was likely due to the fragmented and incomplete nature of the draft genome assemblies. Capture in general was successful for the related species, suggesting that baits designed for a single species are likely to successfully capture sequences from congeners. From these data, we called approximately 10 million SNPs and INDELs in each species from coding regions, introns, untranslated and flanking regions, as well as from the intergenic space. Our study demonstrates the utility of sequence capture for resequencing in complex conifer genomes, suggests guidelines for improving capture efficiency and provides a rich resource of genetic variants for studies of selection and local adaptation in these species.

    One of the dominant tree species growing within and around Los Alamos National Laboratory (LANL), Los Alamos, NM, lands is the pinon pine (Pinus edulis) tree. Pinon pine is used for firewood, fence posts, and building materials and is a source of nuts for food--the seeds are consumed by a wide variety of animals and are also gathered by people in the area and eaten raw or roasted. This study investigated the (1) concentration of {sup 3}H, {sup 137}Cs, {sup 90}Sr, {sup tot}U, {sup 238}Pu, {sup 239,240}Pu, and {sup 241}Am in soils (0- to 12-in. [31 cm] depth underneath the tree), pinon pine shoots (PPS), and pinon pine nuts (PPN) collected from LANL lands and regional background (BG) locations, (2) concentrations of radionuclides in PPN collected in 1977 to present data, (3) committed effective dose equivalent (CEDE) from the ingestion of nuts, and (4) soil to PPS to PPN concentration ratios (CRs). Most radionuclides, with the exception of {sup 3}H in soils, were not significantly higher (p < 0.10) in soils, PPS, and PPN collected from LANL as compared to BG locations, and concentrations of most radionuclides in PPN from LANL have decreased over time. The maximum net CEDE (the CEDE plus two sigma minus BG) at the most conservative ingestion rate (10 lb [4.5 kg]) was 0.0018 mrem (0.018 {micro}Sv). Soil-to-nut CRs for most radionuclides were within the range of default values in the literature for common fruits and vegetables.

  6. Comparison of Methods for Protein Extraction from Pine Needles

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    Extraction of proteins from pine needles for proteomic analysis has long been a challenge for scientists. We compared three different protein extraction methods including sucrose, Tris-HCl and trichloroacetic acid (TCA)/acetone (TCA method) to determine their efficiency in separating pine needle proteins by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and two-dimensional PAGE (2D-PAGE). Proteins were then separated by SDS-PAGE. Among three methods the method using sucrose extraction buffer showed the highest efficiency and highest quality in separating proteins. In addition, clearer and more stable strips were detected by SDS-PAGE using sucrose extraction buffer. When the proteins extracted using sucrose extraction buffer were separated by 2D-PAGE, more than 300 protein spots, with isoelectric points (PI) ranging from 4.0 to 7.0 and molecular weights (MW) from 6.5 to 97.4 kD, were observed. This confirmed that the method with sucrose extraction buffer was an efficient and reliable method for extracting proteins from pine needles.

    Full Text Available The durability of Scots pine heartwood has previously been shown to be affected by the industrial drying process of sawn lumber. The durability of heartwood from boards dried at temperatures between 20°C-110°C was studied by measuring the mass loss in a decay test with a brown rot fungus (Coniophora puteana, and the concentration of total phenolics was measured according to the Folin-Ciocalteu (FC assay. The relation between mass loss and phenolics in dried heartwood showed a weaker negative correlation at lower levels of phenolics as compared to the strong relationship found in a study on heartwood from standing Scots pine trees. Mass loss in dried heartwood showed a weak negative correlation to density. Heating of extractives-rich green sawdust under moist conditions resulted in a reduction of phenolics with temperature up to 180 oC and with increasing time. The concentration of phenolics in heated, green sawdust was higher in extractives-rich pine heartwood than in heartwood with a normal extractives content.

In addition the influence of bacteria on fungal biomass production and the relationship between ectomycorrhizal fungi and fungi pathogenic to root of pine seedlings were determined. In general, the shoot/root ratio was higher in plants inoculated with Hebeloma crustuliniforme and bacteria than in the control seedlings (grown only under sterile conditions. In non-sterile substrate the root/shoot ratio of the mycorrhizal seedlings was lower as compared to the control. Similar phenomenon was noted in plants inoculated with the mycorrhizal fungus Pisolithus tinetorius. The bacteria used as well as the time of introduction of these organisms into the cultures of mycorrhiza fungi affected the production of fungal biomass. Hebeloma crustuliniforme and Pisolithus tinctorius inhibited the growth of Rizoctonia solani and Fusarium oxysporum fungi pathogenic to pine seedlings.

    Savi's pine vole (Microtus savii) is a rodent species of the Cricetidae family, inhabiting southern European agroecosystems. It is considered to be the main cause of rodent-attributed damage in Italy. To achieve an effective management, detailed knowledge of this species is needed. However, the available information about this species is fragmentary and incomplete. In this paper, the existing knowledge of Savi's pine vole taxonomy, reproduction, population dynamics, habitat and food preferences is reviewed in order to organise available information and identify priority areas of future research. Some of the changes in farming practices that have occurred in recent decades may have increased the impact of Savi's pine vole populations in crop fields. To manage this pest species effectively, an integrated strategy is recommended (involving habitat management, trapping and, when appropriate, the use of rodenticides). The apparent lack of cyclical population outbreaks and the relatively small litter size and long gestation and interpartum period of this species suggest that it could be more manageable than other vole species, while its strict herbivorous diet, stable population size in open habitats and wide distribution seem to indicate it as an ideal model species for risk assessment studies. © 2015 Society of Chemical Industry.

    Full Text Available This article presents a skeleton of a potential paradigm of human flourishing and happiness in a free society. It is an exploratory attempt to construct an understanding from various disciplines and to integrate them into a clear, consistent, coherent, and systematic whole. Holding that there are essential interconnections among objective ideas, the article specifically emphasizes the compatibility of Aristotelianism, Austrian Economics, Positive Psychology, and Ayn Rand’s Objectivism arguing that particular ideas from these areas can be integrated into a paradigm of human flourishing and happiness based on the nature of man and the world. Such a paradigm will help people to understand the world and to survive and flourish in it. It is hoped that the paradigm will grow and evolve as scholars engage, question, critique, interpret, and extend its ideas. Our goal is to have a paradigm that accords with reality and there is always more to learn from reality.

  4. Modality-dependent dose requirements in the Austrian breast cancer early detection program. First results from technical quality assurance

    International Nuclear Information System (INIS)

    The Austrian Breast Cancer Early Detection Program (BKFP) has officially started in January 2014. In order to ensure that all participating women can rely on a sufficient cancer detection rate while at the same time the required dose is as low as reasonably achievable, all participating radiology institutes (approx. 200) have to fulfill strict quality assurance requirements. The control and certification is performed by the Reference Center for Technical Quality Assurance (RefZQS), which has been developing the methods and tolerances in a pilot project since 2007. The limits are defined in the EUREF-Oeprotocol which is based on the European EPQC guidelines. From the requirement for optimized image quality while simultaneously following the ALARA principle, we found modality-dependent dose requirements, which we had expected but which have now been compiled for the first time for Austria.

    Criteria, scoring systems, and treatment algorithms for myelodysplastic syndromes (MDS) have been updated repeatedly in recent years. This apparently results from increased awareness and early recognition of the disease, an increasing number of new diagnostic and prognostic markers and tools, and new therapeutic options that may change the course and thus prognosis in MDS. To address these challenges and to create useful new diagnostic and prognostic parameters and scores, the German-Austrian Working Group for Studying Prognostic Factors in MDS was established in 2003 and later was extended to centers in Switzerland (D-A-CH group). In addition, the group cooperates with the European LeukemiaNet, the MDS Foundation, and other national and international working groups in order to improve diagnosis and prognostication. The current article represents a meeting report from the latest workshop organized by the group in Vienna in October 2008. PMID:19148644

    The introduction of alien plants can influence biodiversity and ecosystems. However, its consequences for soil microbial communities remain poorly understood. We addressed the impact of alien ectomycorrhizal (EcM) pines on local arbuscular mycorrhizal (AM) fungal communities in two regions with contrasting biogeographic histories: in South Africa, where no native EcM plant species are present; and in Argentina, where EcM trees occur naturally. The effect of alien pines on AM fungal communities differed between these regions. In South Africa, plantations of alien EcM pines exhibited lower AM fungal richness and significantly altered community composition, compared with native fynbos. In Argentina, the richness and composition of local AM fungal communities were similar in plantations of alien EcM pines and native forest. However, the presence of alien pines resulted in slight changes to the phylogenetic structure of root AM fungal communities in both regions. In pine clearcut areas in South Africa, the richness and composition of AM fungal communities were intermediate between the native fynbos and the alien pine plantation, which is consistent with natural regeneration of former AM fungal communities following pine removal. We conclude that the response of local AM fungal communities to alien EcM pines differs between biogeographic regions with different histories of species coexistence. PMID:27056916

    2016-01-01

    The use of antibiotics in livestock production is coming under growing criticism. Beside overall antimicrobial use, specific substances listed by the WHO as "highest priority critically important antimicrobials" (HPCIAs)--these include fluoroquinolones, macrolides, 3rd and 4th generation cephalosporins, as well as glycopeptides--have been placed under specific restrictions and should only be applied in particular cases according to strict indication criteria. In this study, the consumption of antimicrobial substances on Austrian dairy farms was evaluated quantitatively. The data covered 8,027 prescription records on the use of antibiotics on 465 dairy farms. Eleven veterinary practices provided data from between four to 27 months during the period from 2008 to 2010 and the total consumption of antimicrobials was estimated. The amount of active substance(s) in grams used per livestock unit (g/LU) per year and the number of product-related daily doses used per livestock unit (n PrDD(LU)/LU) per year were determined as units of measurement. These parameters were estimated by applying Monte Carlo simulation techniques, respecting variances in annual working days of the veterinary practices as well as variances in the proportion of non-treated populations. Total antimicrobial consumption in the population-at-risk was determined to be 2.59 g/LU and 1.30 PrDD(LU)/LU per year. HPCIAs were used at a proportion of 24.6% (0.31 PrDD(LU)/LU) of the total consumption of antimicrobials for systemic and intramammary use. Of these, 3rd and 4th generation cephalosporins were most frequently administered, particularly for the treatment of mastitis and foot diseases. The total consumption of antimicrobials in Austrian dairy cattle production is negligible compared to their use in pig and poultry production systems. However, the use of HPCIAs, especially 3rd and 4th generation cephalosporins, should be minimised further. PMID:27344910

  9. Attrition in the Austrian Generations and Gender Survey: Is there a bias by fertility-relevant aspects?

    Isabella Buber-Ennser

    2014-08-01

    Full Text Available Background: In longitudinal research the loss of sample members between waves is a possible source of bias. It is therefore crucial to analyse attrition. Objective: This paper analyses attrition in a longitudinal study on family and fertility, by distinguishing between attrition due to non-contact and attrition due to non-cooperation. Methods: Based on the first two waves of the Austrian Generations and Gender Survey, the two components of attrition are studied separately by using bivariate as well as multivariate methods. Moreover, overall dropout - the combination of both components - isanalysed. Apart from various socio-economic characteristics and data collection information, the study focuses on fertility-relevant variables such as fecundity, fertility intentions, sexual orientation, and traditional attitudes. Results: Fecundity, fertility intentions, and homosexual relationships are associated with higher attrition due to non-cooperation in bivariate analyses, but have no explanatory power inthe multivariate model. Pregnancy and traditional attitudes towards marriage are associated with significantly lower attrition due to non-cooperation in the multivariate context. Overall dropout is significantly lower only among persons with traditionalattitudes towards marriage, although small in size and statistical significance. Moreover, various individual and regional characteristics are significantly associated with dropout, with differences between attrition due to non-contact and attrition due to non-cooperation. Conclusions: Detailed insights into attrition are not only important when using longitudinal data and interpreting results, but also for the design of future data collections. The Austrian GGS panel has a relatively low dropout (22Š and is affected by a small bias towards familyoriented persons as well as less-educated respondents and persons with migrationbackgrounds, but the data can be used without concern about selectivity.

    Full Text Available Long-Term Socio-Ecological Research (LTSER is an inter- and transdisciplinary research field addressing socio-ecological change over time at various spatial and temporal scales. In the Austrian Eisenwurzen region, an LTSER platform was founded in 2004. It has fostered and documented research projects aiming at advancing LTSER scientifically and at providing regional stakeholders with relevant information for sustainable regional development. Since its establishment, a broad range of research activities has been pursued in the region, integrating information from long-term ecological monitoring sites with approaches from social sciences and the humanities, and in cooperation with regional stakeholders. Based on the experiences gained in the Eisenwurzen LTSER platform, this article presents current activities in the heterogeneous field of LTSER, identifying specific (inter-disciplinary contributions of three research strands of LTSER: long-term ecological research, socio-ecological basic research, and transdisciplinary research. Given the broad array of diverse contributions to LTSER, we argue that the platform has become a relevant “boundary organization,” linking research to its regional non-academic context, and ensuring interdisciplinary exchange among the variety of disciplines. We consider the diversity of LTSER approaches an important resource for future research. Major success criteria of LTSER face specific challenges: (1 existing loose, yet stable networks need to be maintained and extended; (2 continuous generation of and access to relevant data needs to be secured and more data need to be included; and (3 consecutive research projects that have allowed for capacity building in the past may be threatened in the future if national Austrian research funders cease to provide resources.

  11. Determination of eye lens doses and identification of risk groups among radiation exposed workers. An Austrian pilot study

    International Nuclear Information System (INIS)

    On European level, in 2014 the dose limit for the lens of the eye of radiation exposed workers has been reduced from 150 to 20 mSv per year (2013/59/Euratom). Data about eye lens exposition measured under realistic operational conditions of Austrian radiation exposed workers is sparse and there is no information to verify, if all professional groups identified to be at risk for elevated eye doses will remain below the new annual dose limit. Therefore, financed by the Austrian Workers Compensation Board, AUVA, a pilot study has been initiated to answer this question. Based on published information professional groups of radiation exposed workers and operational tasks with an enhanced risk of elevated eye lens doses have been identified. By dosimetric measurements with volunteers (forehead dose meters and parallel measurements with whole-body TL-dose meters above and under the lead apron) realistic lens doses will be estimated during selected radiation exposed tasks. Comparison of yielded doses will show whether a TLD outside the apron could serve as an alternative to forehead dose meters dedicated to measure eye lens doses. Measurements with leaded protective eyewear based on IEC61331 yield results for lead equivalent in good agreement with manufacturers' information. Results for eye lens doses determined by use of a RANDO head phantom and a standardized phantom simulating a body in a typical exposition situation for interventional radiologists show that wearing of leaded goggles allows for a 90% dose reduction. Under such conditions the eye lens dose is dominated by backscatter and stray radiation from the operator's head and patient body. This has to be considered for the evaluation of protective effectiveness for leaded eye wear.

    We study noncommutative black holes, by using a diffeomorphism between the Schwarzschild black hole and the Kantowski-Sachs cosmological model, which is generalized to noncommutative minisuperspace. Through the use of the Feynman-Hibbs procedure we are able to study the thermodynamics of the black hole, in particular, we calculate Hawking's temperature and entropy for the 'noncommutative' Schwarzschild black hole.

    The quantum statistics of charged, extremal black holes is investigated beginning with the hypothesis that the quantum state is a functional on the space of closed three-geometries, with each black hole connected to an oppositely charged black hole through a spatial wormhole. From this starting point a simple argument is given that a collection of extremal black holes obeys neither Bose nor Fermi statistics. Rather they obey an exotic variety of particle statistics known as ``infinite statist...

    The exact solutions of electrically charged phantom black holes with the cosmological constant are constructed. They are labelled by the mass, the electrical charge, the cosmological constant and the coupling constant between the phantom and the Maxwell field. It is found that the phantom has important consequences on the properties of black holes. In particular, the extremal charged phantom black holes can never be achieved and so the third law of thermodynamics for black holes still holds. ...

    The current unprecedented outbreak of mountain pine beetle (Dendroctonus ponderosae) in lodgepole pine (Pinus contorta) forests of western Canada has resulted in a landscape consisting of a mosaic of forest stands at different stages of mortality. Within forest stands, understory communities are the reservoir of the majority of plant species diversity and influence the composition of future forests in response to disturbance. Although changes to stand composition following beetle outbreaks are well documented, information on immediate responses of forest understory plant communities is limited. The objective of this study was to examine the effects of D. ponderosae-induced tree mortality on initial changes in diversity and productivity of understory plant communities. We established a total of 110 1-m2 plots across eleven mature lodgepole pine forests to measure changes in understory diversity and productivity as a function of tree mortality and below ground resource availability across multiple years. Overall, understory community diversity and productivity increased across the gradient of increased tree mortality. Richness of herbaceous perennials increased with tree mortality as well as soil moisture and nutrient levels. In contrast, the diversity of woody perennials did not change across the gradient of tree mortality. Understory vegetation, namely herbaceous perennials, showed an immediate response to improved growing conditions caused by increases in tree mortality. How this increased pulse in understory richness and productivity affects future forest trajectories in a novel system is unknown. PMID:25859663

  19. Effects of a Severe Mountain Pine Beetle Epidemic in Western Alberta, Canada under Two Forest Management Scenarios

    International Nuclear Information System (INIS)

    We used a simulation model to investigate possible effects of a severe mountain pine beetle (Dendroctonus ponderosae Hopkins) epidemic under two management scenarios in Alberta, Canada. Our simulated outbreak was based on the current epidemic in British Columbia, which may kill close to 80% of the province's pine volume. Our two management scenarios were conventional harvest and a pine-reduction strategy modeled on a component of Alberta's Mountain Pine Beetle Management Strategy. The pine strategy seeks to reduce the number of susceptible pine stands by 75% over the next 20 years through targeted harvesting by the forest industry. Our simulations showed that the pine strategy could not be effectively implemented, even if the onset of the beetle outbreak was delayed for 20 years. Even though we increased mill capacity by 20% and directed all harvesting to high volume pine stands during the pine strategy's surge cut, the amount of highly susceptible pine was reduced by only 43%. Additional pine volume remained within mixed stands that were not targeted by the pine strategy. When the outbreak occurred in each scenario, sufficient pine remained on the landscape for the beetle to cause the timber supply to collapse. Alternative management approaches and avenues for future research are discussed.

    The last three years have again seen new exciting developments in the area of higher dimensional black objects. For black objects with noncompact higher dimensions, the solution space was exlored further within the blackfold approach and with numerical schemes, yielding a large variety of new families of solutions, while limiting procedures created so-called super-entropic black holes. Concerning compact extra dimensions, the sequences of static nonuniform black strings in five and six dimensions were extended to impressively large values of the nonuniformity parameter with extreme numerical precision, showing that an oscillating pattern arises for the mass, the area or the temperature, while approaching the conjectured double-cone merger solution. Besides the presentation of interesting new types of higherdimensional solutions, also their physical properties were addressed in this session. While the main focus was on Einstein gravity, a significant number of talks also covered Lovelock theories.

    Vast areas of the land in the Southeastern United States are under pine forests managed primarily for timber and related byproducts. Evapotranspiration (ET) is the major loss in the water balance of this forest ecosystem. A long-term (1988-2008) study to evaluate hydrologic and nutrient balance during a life cycle of a pine stand was just completed. The study used both monitoring and modeling approaches to evaluate hydrologic and water quality effects of silvicultural and water management treatments on three 25 ha experimental watersheds in eastern North Carolina (NC). The research was extended in 2009 to include a dedicated energy crop, switchgrass (Panicum virgatum), by adding an adjacent 25 ha watershed. These multiple watersheds are being used to evaluate the hydrologic and water quality effects of switchgrass alone, young pine with natural understory, and young pine with switchgrass intercropping compared to the control (pine stand with a natural understory). The biofuels study has been further expanded to two other southern states, Alabama (AL) and Mississippi (MS). Each has five small watersheds (PVI) will be developed using the R and NIR bands, vegetation density, and background soil reflectance as necessary. Landsat and high resolution aerial imageries of vegetation and soils will be used. IDRISI Taiga software will be used for the indices development. The forested vegetation health will be correlated to the leaf chlorophyll content for determining the vegetation health with a subsequent derivation of available plant water for radiation. Models will be developed to correlate the plant and soil available water to different vegetation indices. Correlation models will also be developed to obtain information on climatic parameters like surface air temperature, net radiation, albedo, soil moisture content, and stomatal water availability from Landsat imageries. On-site weather parameters used for the PET estimates will be combined with other vegetation

    Full Text Available Understanding how the planting of non-native species impacts native vegetation is of most importance for forest management, as introduced species may alter environmental conditions with respect to soil composition, light intensity, and species composition. Here, we compared the stand structure, understory vegetation and site properties of a natural Scots pine (Pinus sylvestris L. stand with Norway spruce (Picea abies (L. Karst. and European beech (Fagus sylvatica L. as the second tree layer. We recorded saplings and species and their abundance in the understory vegetation, the thicknesses of organic (O and humus (A soil layers, soil pH and light indexes in nine Scots pine stands with a second tree layer of beech and in nine control pine stands with a second tree layer of spruce. An ordination method was used to analyze all the data together and ANOVA to determine whether there were differences between stands. We found that species diversity in pine stands with planted beech as the second layer was lower than in pine stands with spruce as the second layer. In pine stands with beech as the second tree layer, shrub, herb and moss cover was significantly lower, and the soil humus layer and organic soil layer were thicker and thinner, respectively. Stand parameters such as mean volume and mean annual increment of the second tree layer were significantly higher in pine stands with planted beech as the second tree layer than in pine stand with spruce as the second tree layer. The mean volume and the mean annual increment of the first tree layer dominated by Scots pine did not differ significantly between stands with planted beech and those with natural spruce. Scots pine stands with a beech second layer had negative effects on understory species richness and abundance. This effect was most likely due to the lower light transmittance and poor physical properties of the forest-floor litter in the Scots pine stands with planted beech.

  5. Limber Pine (Pinus flexilis James), a Flexible Generalist of Forest Communities in the Intermountain West.

    As forest communities continue to experience interactions between climate change and shifting disturbance regimes, there is an increased need to link ecological understanding to applied management. Limber pine (Pinus flexilis James.), an understudied species of western North America, has been documented to dominate harsh environments and thought to be competitively excluded from mesic environments. An observational study was conducted using the Forest Inventory and Analysis Database (FIAD) to test the competitive exclusion hypothesis across a broad elevational and geographic area within the Intermountain West, USA. We anticipated that competitive exclusion would result in limber pine's absence from mid-elevation forest communities, creating a bi-modal distribution. Using the FIAD database, limber pine was observed to occur with 22 different overstory species, which represents a surprising number of the woody, overstory species commonly observed in the Intermountain West. There were no biologically significant relationships between measures of annual precipitation, annual temperature, or climatic indices (i.e. Ombrothermic Index) and limber pine dominance. Limber pine was observed to be a consistent component of forest communities across elevation classes. Of the plots that contained limber pine regeneration, nearly half did not have a live or dead limber pine in the overstory. However, limber pine regeneration was greater in plots with higher limber pine basal area and higher average annual precipitation. Our results suggest limber pine is an important habitat generalist, playing more than one functional role in forest communities. Generalists, like limber pine, may be increasingly important, as managers are challenged to build resistance and resilience to future conditions in western forests. Additional research is needed to understand how different silvicultural systems can be used to maintain multi-species forest communities. PMID:27575596

  6. Nonstationary analogue black holes

    International Nuclear Information System (INIS)

    We study the existence of analogue nonstationary spherically symmetric black holes. The prime example is the acoustic model see Unruh (1981 Phys. Rev. Lett. 46 1351). We consider also a more general class of metrics that could be useful in other physical models of analogue black and white holes. We give examples of the appearance of black holes and of disappearance of white holes. We also discuss the relation between the apparent and the event horizons for the case of analogue black holes. In the end we study the inverse problem of determination of black or white holes by boundary measurements for the spherically symmetric nonstationary metrics. (paper)

    Black holes are dark dead stars. Neutron stars are giant magnets. As the neutron star orbits the black hole, an electronic circuit forms that generates a blast of power just before the black hole absorbs the neutron star whole. The black hole battery conceivably would be observable at cosmological distances. Possible channels for luminosity include synchro-curvature radiation, a blazing fireball, or even an unstable, short-lived black hole pulsar. As suggested by Mingarelli, Levin, and Lazio, some fraction of the battery power could also be reprocessed into coherent radio emission to populate a subclass of fast radio bursts.

    Asymptotically flat black holes in $2+1$ dimensions are a rarity. We study the recently found black flower solutions (asymptotically flat black holes with deformed horizons), static black holes, rotating black holes and the dynamical black flowers (black holes with radiative gravitons ) of the purely quadratic version of new massive gravity. We show how they appear in this theory and we also show that they are also solutions to the infinite order extended version of the new massive gravity, that is the Born-Infeld extension of new massive gravity with an amputated Einsteinian piece. The same metrics also solve the topologically extended versions of these theories, with modified conserved charges and the thermodynamical quantities, such as the Wald entropy. Besides these we find new conformally flat radiating type solutions to these extended gravity models. We also show that these metrics do not arise in Einstein's gravity coupled to physical perfect fluids.

    2011-05-01

    The current epidemic of the mountain pine beetle (MPB), an indigenous pest of western North American pine, has resulted in significant losses of lodgepole pine. The leading edge has reached Alberta where forest composition shifts from lodgepole to jack pine through a hybrid zone. The susceptibility of jack pine to MPB is a major concern, but there has been no evidence of host-range expansion, in part due to the difficulty in distinguishing the parentals and their hybrids. We tested the utility of a panel of microsatellite loci optimized for both species to classify lodgepole pine, jack pine and their hybrids using simulated data. We were able to accurately classify simulated individuals, and hence applied these markers to identify the ancestry of attacked trees. Here we show for the first time successful MPB attack in natural jack pine stands at the leading edge of the epidemic. This once unsuitable habitat is now a novel environment for MPB to exploit, a potential risk which could be exacerbated by further climate change. The consequences of host-range expansion for the vast boreal ecosystem could be significant. PMID:21457381

Carnaby's Cockatoos fed throughout these plantations and removed almost the entire annual crop of pine cones. Peak cockatoo abundance coincided with pine seed maturation. Pine seed had energy and protein contents equivalent to native food sources and, critically, is available in summer when breeding pairs have young offspring to feed. This strong and enduring ecological association clearly suggests that removing pine will have a significant impact on this endangered species unless restoration strategies, to establish alternative food sources, are implemented.
