1. 1. Adjusting to the extreme : Thermal adaptation in a freshwater gastropod

   Författare :Magnus Johansson; Laurila Anssi; Robby Stoks; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radix balthica; Lake Mývatn; geothermal springs; thermal adaptation; isolation by environment; population structure; gene flow; cogradient variation; AFLP; thermal preference; CTmax; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

   Sammanfattning : Temperature is a ubiquitous force influencing biological processes ranging from cellular responses to life span. The thermal environment for many organisms is predicted to change with globally increasing temperatures and studies conducted in natural systems incorporating various evolutionary forces, such as gene flow, is needed.

3. 2. The Physical Environment and Occupant Thermal Perceptions in Office Buildings An Evaluation of Sampled Data from Five European Countries

   Författare :John Leland Stoops; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal sensation; Europe; thermal preference; seasonal variation; office buildings; temperature perception; outdoor temperature; interior temperature; field study; thermal comfort; Clo; Met; carbon dioxide;

   Sammanfattning : The results from a large field study of thermal comfort in European office buildings are reported. Measurements of physical environmental conditions and occupant perceptions were collected over sixteen months from twenty-six different office buildings located in France, Greece, Portugal, Sweden and the UK.

4. 3. Single and Double Skin Glazed Office Buildings - Analyses of Energy Use and Indoor Climate

   Författare :Harris Poirazis; Avdelningen för Energi och byggnadsdesign; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal environment; indoor climate; energy use; building performance; building simulations; double skin façades; Glazed office buildings; single skin façades; thermal comfort;

   Sammanfattning : The energy efficiency and thermal performance of highly glazed office buildings are often questioned. However, nowadays glazed buildings are increasingly being built around the world, mainly due to an architectural trend, followed by the preference of companies to a distinctive image that a glazed office building can provide.

5. 4. Growth, Characterization, and Thermal Stability of CeO2 Thin Films

   Författare :Sissel N. Jacobsen; David K. Fork; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Rare earth oxides are potentially useful materials in various optical electronic, and catalytic devices. The characteristics of such devices are strongly dependent on the interface structure of heterojunctions, hence engineering of the performance can be achieved through tailoring of the micro- and/ or surface structure.

7. 5. Evolution and control of the three dimensional functional microstructure of Polymer:Fullerene photovoltaic blends

   Författare :Olof Bäcke; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crosslinking; fullerene crystals; tomography; transmission electron mi- croscopy; organic solar cell; in situ; polymer:fullerene film; thermal degradation;

   Sammanfattning : Polymer:fullerene bulk-heterojunction thin films show great promise for use as active layers in organic solar cells. However, their low thermal stability is a hindrance that complicates the manufacturing and influences the lifetime of devices. LÄS MER
