2. 1. Studies in pest control for cultural property

   Author : Thomas Strang; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Pest control; cultural property collections; insect; mould; environment; integrated pest management; IPM; thermal control; pest risk to museum collections;

   Abstract : This thesis considers discrete problems of protecting cultural property from pests and examines some of the solutions. Recent decades have seen a large change in how fumigants and pesticides are used in collections of cultural property. READ MORE

4. 2. In the wake of the Green Revolution : Environmental and socioeconomic consequences of intensive rice agriculture - The Problems of weeds in Muda, Malaysia

   Author : Magnus Jirström; Institutionen för kulturgeografi och ekonomisk geografi; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; intensification; land degradation; rice agriculture; IPM integrated pest management ; Social geography; sustainable agriculture; Green Revolution; Socialgeografi;

   Abstract : The agricultural intensification strategies represented by the Green Revolution have since the mid-1960s had a very positive impact on food-grain production in Asia. Presently, however, a post-Green Revolution phase of declining growth in output and productivity is experienced in many of the areas where intensification took place. READ MORE

5. 3. Developing IPM tools for greenhouse cucumber production in Sweden – a participatory action research approach : control of the European tarnished plant bug and cucurbit powdery mildew

   Author : Mira Rur; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Two of the most important plant protection problems in Swedish cucumber production are the European Tarnished Plant Bug (ETPB), and Cucurbit Powdery mildew (CPM). The control of the ETPB relies on Imidacloprid, a pesticide, which breaks down slowly and is harmful to beneficial insects. READ MORE

6. 4. Synchronous Reluctance Machine (SynRM) in Variable Speed Drives (VSD) Applications

   Abstract : This thesis is comprehensively dedicated to the theoretical and experimental reevaluation of the Synchronous Reluctance Machine (SynRM). A simple approach to derive the SynRM main characteristics and behavior is followed. An introduction to an evaluation of the different control strategies in is given. READ MORE

7. 5. Geometry Optimization of an Interior Permanent Magnet Machine for Electric Vehicles - Life Cycle Cost Minimization for City, Rural and Highway Driving

   Author : Elisabet Jansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; Finite Element Analysis; Interior Permanent Magnet Machine; Drive Cycles; Life Cycle Cost; Battery Electric Vehicle; Electric Machine Design;

   Abstract : This thesis investigates the benefits of customizing an Interior Permanent magnet Machine (IPM) for a specific combination of city, rural and highway driving. Focus lies on the potential to reduce the Life Cycle Cost (LCC) of the IPM and power electronic converter, for an example Battery Electric Vehicle (BEV), by custom-making the IPM. READ MORE
