2. 1. Competition in caddis larvae

   Author : Göran Englund; S. Kohler; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Agrypnia pagetana; Arctopsyche ladogensis; emigration; fighting behaviour; habitat selection; Hydropsyche siltalai; Hydropsychidae; immigration; predation; resource competition; sequential assessment game;

   Abstract : This thesis deals with behavioural strategies used by caddis larvae in pairwise contests and when selecting microhabitats. Effects of caddis larvae on survival and habitat selection of other insect taxa have also been studied. READ MORE

4. 2. Settlement of bivalve larvae : the role of larval behavior, predation and hydrodynamics

   Author : Carl André; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : .... READ MORE

5. 3. Functional study of hemolymph coagulation in Drosophila larvae

   Author : Zhi Wang; Ulrich Theopold; Brian Lazzaro; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; innate immunity; hemolymph coagulation; clot components; Drosophila larvae; Molecular Biology; molekylärbiologi;

   Abstract : Many pathogen infections in nature are accompanied by injury and subsequent coagulation. Despite the contribution of hemolymph coagulation to wound sealing, little is known about its immune function. READ MORE

6. 4. Interactions between polymers and the environment

   Author : Nazanin Alipour; Mikael S. Hedenqvist; Antal Boldizar; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deltamethrin; piperonyl butoxide; polyethylene; migration; multilayer film; EVOH; n-hexane; crystallization; mechanical properties; X-ray scattering; swelling; larvae; protein; lipid; moisture sorption; release; nanoclay; polypropylene; degradation; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : This dissertation addresses the structure and properties of a number of polymer-based materials when they come into contact with specific environments. The first part describes the migration and depletion of active substances from insecticide-impregnated polyethylene sheets in water and air at different humidity levels and higher temperatures.
