1. 11. Ecological effects of pesticides in freshwater model ecosystems

   Författare :Lina Wendt-Rasch; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marine biology; aquatic ecology; limnology; Marinbiologi; Hydrobiology; community; zooplankton; algae; herbicide; insecticide; pesticide mixture; macrophytes; cypermethrin; metsulfuron-methyl; risk assessment; pesticides; microcosms; limnologi; akvatisk ekologi;

   Sammanfattning : In this thesis I have investigated the effects of pesticide exposure on the ecosystem level using various types of experimental ecosystems, i.e. microcosms. The direct effect of exposure to cyperemthrin, a pyretroid insecticide, was a rapid decrease of crustancean zooplankton in enclosures in a lake. LÄS MER

3. 12. Usability Requirements for User-Controlled Robotic Eating Aids

   Författare :Ann-Louise Lindborg; Maria Lindén; Albert Westergren; Annica Kristoffersson; Martin Ekström; Johan Blomkvist; Mälardalens universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotic eating aid; eating device; eating aid; usability requirement; user centered design; elektronik; Electronics;

   Sammanfattning : The meal is fundamental in terms of nutrition but also from a social perspective. To be able to eat independently is described as important for the meal experience.  The development of a robotic eating aid called Bestic and the evolvement of a list of usability criteria for such an aid are described in this thesis.

4. 13. Influence of water conditions on growth and mineral nutrient uptake of native plants on clacareous soil

   Författare :Aparna Misra; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; agricultural hydrology; Lantbrukshydrologi; marklära; Växtekologi; Plant ecology; wet growing; wet dry cycles; soil solution; soil moisture; pH; nutrient poor soil; mineral nutrients; dry growing; Bicarbonate; calicole; Soil Science;

   Sammanfattning : The studies presented in Papers I to IV illustrate the importance of soil moisture in soil solution chemistry and response of native plants to the changes induced by change in moisture regime. With the help of glasshouse experiments I tried to study the influence of different treatments of soil moisture conditions on the mineral uptake by native plants of calcareous soil. LÄS MER

5. 14. I väntan på asyl. Retorik och praktik i svensk flyktingpolitik

   Författare :Eva Norström; Avdelningen för etnologi; []
   Nyckelord :HUMANIORA; HUMANITIES; Emigration and immigration law; Right of - Government policy; Archetype Psychology ; Cultural anthropology; Asylum; Kulturantropologi; ethnology; etnologi; UNHCR; Ethics; Ethnology;

   Sammanfattning : The purpose of my research is to examine the translation of logos into praxis in the handling of asylum-cases in Sweden. My point of departure has been the manner in which society has organised the handling of asylum-cases and the structure of this organisation. LÄS MER

7. 15. Effects of Ischaemia on the Neuroretina and Retinal Blood Vessels

   Författare :Bodil Gesslein; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein kinase C; tumor necrosis factor; mitogen-activated protein kinases; pig; blood vessels; mfERG; Retinal ischaemia; vascular endothelial growth factor; hypoxia-inducible factor;

   Sammanfattning : Identification of the intracellular signal transduction pathways activated in retinal ischaemia may be important in revealing novel pharmacological targets. The retinal blood vessels are key organs in circulatory failure, and in this work the retinal vasculature was therefore examined separately from the neuroretina. LÄS MER
