Grapevine yellows are widespread in many viticultural areas of the world. They are spread by insect vectors. In order to search for the potential vectors of the diseases, research was undertaken to identify the leafhopper and planthopper species present in Austrian vineyards. Particular attention was devoted to find
in the vineyard infected with BN/VK in Burgenland and
in vineyards near the Austrian-Slovenian border. Both vectors and the disease of BN/VK are present in Austria.Regular samplings and checks were taken in three viticultural areas (Lower Austria, Burgenland, Styria) during the vegetation period of 2004, between the beginning of May and the end of October. Samples were obtained with yellow sticky boards, suction sampler and occasionally with sweep net from the canopy of grapevine, the undergrowth and the bordering vegetation.The 5186 leafhopper individuals belonging to 87 species of 5 families were collected during our samplings. The most abundant species trapped in the canopy are members of the Thyphlocybinae subfamily. The predominant species was

was collected in the vineyard located in Burgenland, where BN disease was observed, and also in Styria. More than 10 species, which had been found to be infected by stolbur in previous studies, were also collected.
This study deals with some particular features of commercial arbitration in Austria. The legal framework of arbitration in Austria was changed with an effect of 1st July, 2006, as the Austrian Parliament passed the
2006 in December 2005. This act was proclaimed on the 13th January 2006 and entered into force 1st July in spite of the planned date of 1st January. After having described the significance of arbitration in Austria the author pays special attention to the topic of appointment and challenge of arbitrators. The author compares the rules of the valid Austrian act with the provisions of UNCITRAL Model Law adopted on 21st June, 1985. The author highlights some cases from the legal practice which are considered relevant in the present issue. Finally the author summarizes the provisions of the rules of procedure of International Arbitral Centre of the Austrian Federal Economic Chamber from the point of view of appointment and challenge of arbitrators, which rules have been effective also since 1st July, 2006.

Screening measurements for 3H, 226Ra, 222Rn and 238U in ground water were performed within a ground- and drinking water project in Austria. The aim of this project is to get
an overview of the distribution of natural radionuclide activity concentration levels in ground water bodies. In some cases
this water is used for drinking water abstraction. In this paper methods and results of the screening measurements are presented.
Regions with high activity concentrations were identified and in these regions further investigation for 228Ra, 210Pb and 210Po will be conducted.
Education and Sustainable Development
Current discussions around education for sustainable development (ESD) in Austria focus on the notions of sustainable development, on environmental education (EE), on development education
Migration in Hungary and Austria
There is a significant difference between Hungary and Austria in terms of migration. Regarding global migration patterns, Hungary cannot be considered as an
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.
