2. 1. Plants as Sources of Natural and Effective Acaricides : Against Ixodes ricinus  (Acari: Ixodidae)

   Author : Fawzeia Elmhalli; Giulio Grandi; Richard Wall; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acaricidal; Ixodes ricinus; Libyan plants; essential oils; Plant-derived acaricides.; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

   Abstract : Ticks and tick-borne diseases are major health hazards worldwide, with increasing numbers of cases of Lyme disease and tick-borne encephalitis reported yearly. Meanwhile, concerns about the environmental impact and safety of chemical acaricides are driving research into alternative control methods, such as plant-based acaricides. READ MORE

4. 2. The importance of transport costs for spatial structures and competition in goods and service industries

   Author : Rickard Wall; Jan Owen Jansson; Linköpings universitet; []
   Keywords : Transport costs; Industry location; Spatial competition; Market forms; Industrial Re-Organization; Transportekonomi; Lokalisering; Konkurrens; Materialadministration; Transportorganisation; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

   Abstract : This dissertation deals with market definition and demarcation, and discusses competition and market form classification in the spatial economy. The analytical tool for this study is an extended Location Theory model. READ MORE

5. 3. Asexual embryogenesis in plants

   Author : Boel Mårtensson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systematic botany; two-phase partitioning; somatic embryogenesis; pollen embryogenesis; plasma membrane; peroxidase; Daucus carota isoperoxidase; Nicotiana tabacum; Ca2 transport; cell shape; calmodulin; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

   Abstract : The capacity of somatic cells and pollen grains or microspores to undergo embryogenesis is an important property used in improvement and regeneration of plants. Furthermore, somatic embryogenesis as well as pollen embryogenesis show many similarities with zygotic embryogenesis and are, thus, good model systems. READ MORE

6. 4. Mechanistic Modeling of Wall-Fluid Thermal Interactions for Innovative Nuclear Systems

   Author : Roman Thiele; Henryk Anglart; Xu Cheng; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GEN-IV reactors; Wall heat transfer; Computational Fluid Dynamics; Wall functions; Reactor design; Supercritical water; Liquid metal; Energy Technology; Energiteknik; Fysik; Physics;

   Abstract : Next generation nuclear power plants (GEN-IV) will be capable of not only producing energy in a reliable, safe and sustainable way, but they will also be capable of reducing the amount of nuclear waste, which has been accumulated over the lifetime of current-generation nuclear power plants, through transmutation. Due to the use of new and different coolants, existing computational tools need to be tested, further developed and improved in order to thermal-hydraulically design these power plants. READ MORE

7. 5. UDP-sugar metabolizing pyrophosphorylases in plants : formation of precursors for essential glycosylation-reactions

   Author : Daniel Decker; Leszek A. Kleczkowski; Henrik Vibe Schelle; Umeå universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical library screening; Cell wall synthesis; Glycosylation; Nucleotide sugars; Oligomerization; Protein structure; Reverse chemical genetics; Sugar activation; UDP-sugar synthesis; biokemisk farmakologi; biochemical pharmacology; biokemi; Biochemistry; biology; biologi; molekylärbiologi; Molecular Biology;

   Abstract : UDP-sugar metabolizing pyrophosphorylases provide the primary mechanism for de novo synthesis of UDP-sugars, which can then be used for myriads of glycosyltranferase reactions, producing cell wall carbohydrates, sucrose, glycoproteins and glycolipids, as well as many other glycosylated compounds. The pyrophosphorylases can be divided into three families: UDP-Glc pyrophosphorylase (UGPase), UDP-sugar pyrophosphorylase (USPase) and UDP-N-acety lglucosamine pyrophosphorylase (UAGPase), which can be discriminated both by differences in accepted substrate range and amino acid sequences.
