Hintergrund Mit Juli 2001 schuf Österreich die rechtlichen Voraussetzungen für Babyklappen und anonyme Geburten. In der vorliegenden Studie wurde untersucht, ob mit der anonymen Kindesabgabe ein signifikanter Bruch im längerfristigen Trend der Neonatizide erreicht wurde und wie sich die Zahl der anonym abgegebenen Kinder entwickelt hat. Methoden F...

Following the depletion of inflows and the increased evaporation, the Dead Sea water level has fallen constantly since the 1950s. This paper discusses two scenarios for a possible future development: one follows a supply-driven approach by bringing in more water through a Red-Dead-Conduit. The second scenario assumes that more water could flow from...

The Dead Sea basin plays a major role for regional economic development (industry, tourism and agriculture). This potential is threatened by the steady disappearance of the Dead Sea. Since around 1930 the water level of the Dead Sea has fallen by about 25 m, about half of this alone in the last 20 years. These causes for the decline are a direct re...

This chapter describes a system for public dissemination of environmental maps through an interactive Web-based system. This “EnviroMap” system is a platform in which data holders can publish a raster version of their data and data seekers can get access to these data. For data holders, the system provides a tool for data documentation and upload....

This chapter describes the spatial risk assessment for nitrate pollution of groundwater that supplies the Lower Jordan Valley. The assessment is based on the mapping of inputs and leakage of nitrogen compounds. The major risk factors are uncontrolled urban wastewater disposal and agricultural fertilizer use and irrigation. Solid waste dumps and ind...

This paper describes a method to calculate the spatial variability of the expected annual average ambient air concentration of NOx using standard NOx emission inventories. As the first step, countrywide NOx emission inventories were spatially disaggregated into emission-relevant areas. Pollutant dispersion from emission grids into the neighboring r...

The Lower Jordan Valley is usually regarded a region with severe water scarcity, but this is not the case. The per-capita availability of water is much above the average of the Middle East, but it is regionally unevenly distributed. About 94% of all usable water is used for agriculture; about 2/3 of that has drinking water quality. On the other han...

Publisher Summary This chapter discusses the analysis of total phenols and other oxidation substrates and antioxidants by means of Folin-Ciocalteu reagent. Analyses of the Folin-Ciocalteu (FC) type are convenient, simple, and require only common equipment and have produced a large body of comparable data. Under proper conditions, the assay is inclu...

Using IPCC recommended procedures, anthropogenic emissions of nitrous oxide (N2O) in Austria for the base year 1990 were estimated to be around 4,800 metric tons (t). The uncertainties are high particularly for the emissions from agricultural soils. About 62 % of total emissions come from agriculture, 26 % from the energy sector, and 11 % from the...

Regional emission densities of anthropogenic non-methane volatile organic compounds (NMVOC) in Austria were calculated using statistical information on emission generation activities, emission factors from technical literature, and regional reference data.Total anthropogenic NMVOC emissions in Austria were estimated to be 467,000 metric tons for th...

Im Falle einer großräumigen Verstrahlung nach der Freisetzung von Radionukliden, z.B. nach einem Unfall in einem Kernkraftwerk, läßt sich mit Hilte von OECOSYS rasch eine Prognose für die Beiträge der drei Expositionspfade lnhalation, lngestion und externe Bestrahlung zur Bevölkerungsdosis erstellen. Gezielte Maßnahmen zur Dosisreduktion werden dah...

A review of Austrian research projects and results of acidic precipitation and forest damage research is presented. Data are included for countrywide annual emission rates and the forest damage situation. Wet and bulk deposition data and air quality characteristics are reported for selected monitoring sites. With 86% of pH recordings below 5.1, aci...

Quantitative balances have been made for sugar and oxygen uptake rates during citric acid accumulation by Aspergillus niger: during the first phase of citric acid accumulation (up to 130 h) more sugar is taken up than the production of biomass, CO2 and citric acid account for. In contrast, during later phases of fermentation more citric acid, CO2 a...

The main goal of the Austrian pollution control policy is the reduction of all relevant emissions to the lowest possible level which can be reached by advanced technologies. Generally, air quality is tried to be improved by Emission Standards rather than Ambient Air Quality Standards.

The efficiency of percutane isosorbide dinitrate (ISDN) therapy on 61 subjects with coronary heart diseases (angina pectoris, postinfarction state and myocardial insufficiency) was examined. Serum levels of ISDN in 12 subjects were measured gaschromatographically. The haemodynamic and clinical parameters received, as well as, the reduced attack-not...

Emission inventories require the management, documentation and interrelation of large amount of hetero- geneous data in a user-controlled logic. emikat.at is a system that support those who establish emission inventories and work with it. emikat.at consists of a data administration server and a user interface residing on the users' PC's (client). A...

This paper presents the results of survey research on how people perceive the problem of the shrinking Dead Sea. Our approach emphasizes the concerns and priorities of residents on all sides of the basin. Correlational analysis between survey responses and socio-economic and socio-demographic factors were analyzed. This work is the first cross-cult...
