1. 1. Managing uncertainties in geotechnical parameters : From the perspective of Eurocode 7

   Författare :Anders Prästings; Stefan Larsson; Johan Spross; Rasmus Müller; Kok-Kwang Phoon; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eurocode 7; Characteristic value; Partial-factor method; Reliability-based design; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Geotechnical engineering is strongly associated with large uncertainties. Geotechnical site investigations are made only at discrete points and most of a soil volume is never tested. A major issue is therefore how to cost effectively reduce geotechnical uncertainties with respect to structural performance. LÄS MER

3. 2. Business Model Design for Social Goods and Services in Developing Economies

   Författare :Mirella Lindsay Haldimann; Heiko Gebauer; Aku Valtakoski; Ray Fisk; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : Over the past decade there have been increasing calls for alternative ways of tackling poverty problems in developing economies. Rather than aid or charity approaches that have traditionally dominated this area, an alternative line of discussion around base-of-the-pyramid approaches has emerged which emphasizes the role of innovation and pro-poor entrepreneurship.

4. 3. The influence of soil pH on plant and microbial communities in sandy grasslands

   Författare :Linda-Maria Mårtensson; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; in situ 13CO2 labelling; disturbance; sandy grasslands; species diversity; acidification; soil pH; microbial biomass; C allocation;

   Sammanfattning : Sandy, calcareous grasslands are species rich temperate semi-natural grasslands. The species composition in 136 plots was analysed in relation to soil chemistry parameters; extractable P and N, soil pH and lime content. LÄS MER

5. 4. In-situ activated hydrogen evolution from pH-neutral electrolytes

   Författare :John Gustavsson; Ann Cornell; Olof Forsén; KTH; []
   Nyckelord :molybdate; trivalent cations; electrolysis; hypochlorite reduction; films; electrolysis; chlorate process; molybdat; trivalenta katjoner; elektrolys; hypokloritreduktion; filmer; kloratprocessen; SRA - Energy; SRA - Energi;

   Sammanfattning : The goal of this work was to better understand how molybdate and trivalent cations can be used as additives to pH neutral electrolytes to activate the Hydrogen Evolution Reaction (HER). Special emphasis was laid on the chlorate process and therefore also to some of the other effects that the additives may have in that particular process. LÄS MER

7. 5. Degranulation in macrophages and other leukocytes: regulation by calcium, phosphoinositide 3-kinase, and protein kinase C

   Författare :Claes Nauclér; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lysosomal secretion; neutrophil; Clinical biology; proton pump; Klinisk biologi; exocytosis; lysosomal pH;

   Sammanfattning : Macrophages mediate innate immunity through release of cytokines, eicosanoids, reactive oxygen species as well as through phagocytosis and secretion of lysosomal enzymes. Regulation of lysosomal secretion in macrophages differs in several respects from release of specialized granules in other leukocytes. LÄS MER
