The sources and environmental levels of the PBTs in the countries of Central and Eastern Europe are broadly described. Most of the countries in the region produce and/or formulate pesticides. The pesticide registration is a primary requirement for import, production and distribution. The special attention must be given to unwanted pesticides. The problem of unwanted and expired pesticides pose ...

As the new Editor in Chief, I will use this editorial to give a brief outline of my vision for the future of the journal. As the english-language successor to the dutch-language journal of the Dutch Association for Medical Education (NVMO), ‘Perspectives on Medical Education’ has become a fully-fledged international scientific journal. I commend the editorial board on this achievement. It provi...

A class of heterogeneous catalysts based on commercial bentonite from natural origin, containing at least 80 wt% of montmorillonite clay, was designed to transform selectively and under mild conditions toxic organosulfur and organophosphorus chemical warfare agents into non-noxious products with a reduced impact on health and environment. The bentonite from the natural origin was modified by in...

This paper discusses the role of donor organizations during the transition process of CEE countries. Previous research pointed to them as the ones to blame for the failure of many assistance projects. This paper investigates what those donor organizations have to say themselves. It departs form the theory of social exchange which focuses on situations of imbalance of costs and rewards which is ...

Since late 1980s four systems of stages of higher education and qualifications have been in force in Estonia. The higher education system has been changed or reorganized through three phases of reforms, important periods were in 1989-1991, 1995-1996 and 20012002. The latter phase of reforms was clearly facilitated and conducted by the progressive Bologna process. Similarly to other CEE countrie...

In this paper we discuss the new demands put on university faculty for involvement in delivery of Continuing Engineering Education. CEE programmes are often composed in the same way as on-campus programmes – which means straight forward for teachers to conduct. However, the needs for new knowledge and new competencies in small and medium sized enterprises and for teams in larger enterprises are...

O6-Ethylthioethyldeoxyguanosine has been synthesized from 6-chloro-3',5'-di-O-acetyldeoxyguanosine and characterized by UV, fluorescence, and mass spectrometry. High-pressure liquid chromatography studies have shown that this modified nucleoside is formed when the one-armed sulfur mustard, chloroethyl ethyl sulfide, reacts with deoxyguanosine. This result supports the hypothesis that the mutage...
