4. 2. Non-target Effects of Genetically Modified Trees

   Author : Patrik Blomberg; Anders Wennström; Jan Stenlid; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetically modified; GM trees; secondary metabolism; phytochemistry; Populus; transgenic; non-target effects; natural enemies; plant-pathogen herbivore interaction; environmental effects; parasitic fungi; herbivorous insect; Terrestrial ecology; Terrestisk ekologi;

   Abstract : To date, few studies have focused on the effects of genetically modified trees (GM trees) on the environment. One concern with GM trees is that they may have unanticipated effects on non-target organisms, i.e. effects on organisms that are not direct targets of the genetically modified trait. READ MORE

7. 5. On direct hydrogen fuel cell vehicles : modelling and demonstration

   Author : Kristina Haraldsson; Per Alvfors; Dougal J. Nelson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; direct hydrogen; Proton Exchange Membrane; PEM; fuel cell; fuel cell vehicle; fuel cell hybrid vehicles; on-board hydrogen storage; Kemiteknik; Chemical engineering; Kemiteknik;

   Abstract : In this thesis, direct hydrogen Proton Exchange Membrane (PEM) fuel cell systems in vehicles are investigated through modelling, field tests and public acceptance surveys. A computer model of a 50 kW PEM fuel cell system was developed. The fuel cell system efficiency is approximately 50% between 10 and 45% of the rated power. READ MORE
