1. 1. Spatial variations of the urban climate and its influence on thermal comfort and behaviour

   Författare :Fredrik Lindberg; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sky view factor; air temperature; surface temperature; GIS; raster modelling; mean radiant temperature; globe temperature; the SOLWIEG-model; human behaviour; outdoor activity;

   Sammanfattning : The increased number of people living in urban areas emphasises the need for an improved understanding of how the urban climate affects human activity and behaviour. The spatial and temporal variation of climate within cities is an important factor in people’s health and well-being. LÄS MER

3. 2. Potential impact of climate change on European agriculture: a case study of potato and Colorado potato beetle

   Författare :Bakhtiyor Pulatov; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Colorado potato beetle; climate change; day length; degree day model; frost damage; distribution; temperature; potato; regional climate model; synchrony;

   Sammanfattning : European agriculture is facing the challenge of managing the impact of climate change on food security. Agriculture in a northern temperate climate is likely to benefit from higher temperature and longer growing season while, in the south, crop productivity is likely to decline. LÄS MER

4. 3. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process

   Författare :Abraham Judah Bumalirivu Muwanguzi; Andrey V Karasev; Henrik Saxèn; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural iron ore; iron production; characterization; physical and metallurgical properties; sinter; pellet; direct reduction; low temperature degradation; sample weight; sample positioning; microstructure; reduction degree; solid conversion; Volumetric Model; Grain Model; Random Pore Model; Muko; Uganda;

   Sammanfattning : In the iron production processes, sinters and pellets are mostly used as raw materials due to their consistency with respect to physical and chemical properties. However, natural iron ores, as mined, are rarely used directly as a feed material for iron processing. LÄS MER

5. 4. Heat Flow in Building Components, Experiment and Analysis

   Författare :Petter Wallentén; Institutioner vid LTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiation exchange; longwave; shortwave; transient; frequency analysis; finite difference; measurements; wall; window; heat transfer coefficient; convective; full scale; natural climate; in situ; counter flow insulation; heat transfer; dynamic insulation; temperature; building; solar radiation; window model; Building construction; Byggnadsteknik;

   Sammanfattning : Three building components exposed to natural climate were studied: a dynamic insulation in the ceiling of a house, an outer wall and one window in the same wall. The term dynamic insulation implies that part of the inlet or exhaust air passes through the insulation of a house. LÄS MER

7. 5. Modeling and Optimization of Reversed-Phase Chromatography : Effects of Modulators and Temperature

   Författare :Karolina Arkell; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reversed-phase chromatography; Hydrophobic interaction chromatography; Mechanistic modeling; INSULIN; KCl; Ethanol; Temperature; Multi-objective optimization; Constraint; Solubility;

   Sammanfattning : Many widespread diseases, such as diabetes, various types of cancer, and aggressive versions of influenza, are treated or prevented with biopharmaceuticals. Biopharmaceuticals are drugs that are based on proteins, peptides, antibodies, attenuated viruses (vaccines), and other biomolecules that are synthesized predominately in bacteria, yeast, and mammalian cells.
