1. 1. Thermo-electric temperature measurements in friction stir welding : Towards feedback control of temperature

   Författare :Ana Magalhães; Gunnar Bolmsjö; Jeroen De Backer; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FSW; Robotic; Temperature; TWT; Plunge; Control; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Friction Stir Welding has seen a fast uptake in many industry segments. Mechanical properties superior to fusion welding, the ability to weld "unweldable" aluminium alloys and low distortion are often described as the main reasons for the fast industrial implementation of FSW. Most existing applications consist of long straight welding joints. LÄS MER

3. 2. Bacterial and fungal growth in soil: The effect of temperature and substrate addition

   Författare :Stephanie Reischke; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacterial growth; Fungal growth; Respiration; Carbon loading; Glucose mineralisation; Temperature adaptation; Temperature sensitivity; Temperature dependence;

   Sammanfattning : Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. LÄS MER

4. 3. Factors Affecting Rates of Change in Soil Bacterial Communities

   Författare :Marie Pettersson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Plant ecology; Växtekologi; bacteriology; Microbiology; DGGE; PLFA; TdR-incorporation; function; structure; tolerance; adaptation; pH; soil bacterial community; temperature;

   Sammanfattning : The soil bacterial community is under the constant influence of its environment. Changing any of the factors affecting the bacterial community will induce a selection pressure which, with time, will change the community. In this work the effect of changing the temperature or pH on the soil bacterial community was studied. LÄS MER

5. 4. Patterns of small-scale coastal fisheries and local fisheries management in Tanzania : adaptation to a changing climate

   Författare :Mathew Ogalo Silas; Martin Gullström; Hans W. Linderholm; Mattias Sköld; Patrick Polte; Christina Hicks; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Small-scale fisheries; tropical coastal seascape; nearshore-offshore linkages; coastal ecosystems; fish catch landings; communities; adaptation; climate change; fishing overfishing; Marine Ecotoxicology; marin ekotoxikologi;

   Sammanfattning : Coastal habitats like mangroves, seagrass meadows, coral reefs, and adjacent offshore waters constitute an important part of the tropical coastal seascape. They provide conducive environmental conditions for fish and other marine animals, which serve as food and income for coastal communities around the world. LÄS MER

7. 5. Ecological drivers and genetic signatures of evolutionary divergence and local adaptation in pike (Esox lucius)

   Författare :Johanna Sunde; Anders Forsman; Anssi Laurila; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptation; differentiation; Esox lucius; evolution; gene flow; genetic admixture; genetic structure; microsatellites; pike; RADseq; salinity tolerance; temperature tolerance; Ecology; Ekologi;

   Sammanfattning : The diversity among species, populations, and individuals in nature is astonishing. Genetic and phenotypic variation constitutes the raw material for evolution. It influences how populations respond to changing environments, and can impact long-term survival of species and ecosystem functioning. LÄS MER
