Plant oil derivates as fuels

The dependence of the Hungarian economy on energy imports has already reached that degree, which is forecast in the EU for the average of the community by 2020.

The total quantity of the biomass in Hungary is 350 - 360 mtons, out of which 105 - 110 mtons reproduces itself annualy. The energy content of the yearly produced biomass is as high as 1185 PJ, which is 5% more than the annual energy consumption. The renewable energies which are produced by agriculture could cover 10% of the energy demand of Hungary for a short term.

At our College Faculty in Mezőtúr we have been dealing with the application issues of vegetable oil derivates as fuels since 1990.

Abstract

The aim of this paper is to give an overview of the phenomenon of professionalization that is observable in organizations from the nonprofit sector. Empirical research was conducted among Hungarian nonprofit organizations, and the data were collected within the framework of a country-wide survey. Through the analysis of the research results, the paper provides deeper insights into knowledge about professionalization trends in the nonprofit sector. It proves that organizational development positively impacts nonprofit organizations’ improvement of their professionalization level and the members of these organizations.

Abstract

During our research we utilized data provided by GPS collars to compare the spatial patterns of wild boars living in lowland and high-hilly regions. Five wild boars were fitted with GPS Plus (Vectronic) type collars. The two aforementioned investigated habitat areas were as follows: a high-hilly hunting ground from the foot of the Bodoc Mountains (Covasna County), and the meeting point of Olt and Danube rivers in the southern part of the country (Teleorman County). The average daily wild boar activity varied between 2.9 and 3.1 km in the lowlands and between 3.6 and 4.9 km in the higher situated habitats. The average daily movement area calculated with the minimum convex polygon method was between 60.3 and 112.5 ha/day in the lowlands and between 113.5 and 125.2 ha/day in the high-hilly regions. The movement area of the wild boars calculated with the MCP method varied between 1,060 and 1,2001 hectares in lowlands and between 8,689 and 9,463 hectares in higher altitudes. Our data proved inadequate at testing whether or not large carnivores affect wild boar activity patterns. Habitat use analysis produced interesting results: even in a very diverse habitat, every collared individual preferred green forests. We found negative preference for agricultural fields in both habitats.
