1. 1. Numerical predictions and measurement of non-isothermal airflows : evaluation of buoyant wall jets and airflow through large openings

   Författare :Tobias Törnström; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : How can we attain a good indoor climate and at the same time reduce energy consumption? These issues are of particular interest in countries with cold climates, where the need for heating is large. It is important to design a HV AC (Heating, Ventilation and Air Conditioning) system that achieves a desirable indoor climate, where discomfort due to draft and thermal discomfort is avoided.

3. 2. Modeling Variable Density and Radiation Effects in Turbulent Flames with Fast Chemistry

   Författare :Jonny Nisbet; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The thesis focuses on the less known, but important, aspects of turbulent combustion, namely the variable density and radiation effects. A fundamental discussion of the basic physical phenomena involved in the pressure-density interactions is provided. Current modeling approaches are discussed and simple modifications of the k - .epsilon. LÄS MER

4. 3. A study of finite-size, non-perturbative and anisotropic effects on the Lifshitz-van der Waals forces and torque with material dielectric responses from first-principles calculations

   Författare :Priyadarshini Thiyam; Clas Persson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lifshitz-van der Waals forces; Casimir torque; optical calculations with density functional theory; phosphorus; phosphorene;

   Sammanfattning : The van der Waals and the Casimir-Lifshitz forces are forces of attraction that exist between neutral polarizable bodies due to quantum fluctuations. They can be repulsive depending on the material properties and the geometry of the system. LÄS MER

5. 4. Vpu-mediated intracellular targeting of HIV-1 core protein precursor Pr55[gag] and association of Pr55[gag] with lipid microdomains

   Författare :Kirsi Harila; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : HIV-1 has been suggested to use lipid rafts for assembly and budding. Lipid rafts can be separated from the bulk membranes by extraction with non-ionic detergents, such as Triton X-100 at cold, followed by a density gradient centrifugation. LÄS MER

7. 5. Cytoplasmic mRNP particles in dormant and developing artemia embryos

   Författare :Mats Lake; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In dormant cryptobiotic embryos of Artemia there is a stored pool of messenger RNA (mRNA) associated with the endoplasmic reticulum. Upon resumption of the embryos this latent mRNA is activated and used in the protein synthesis. LÄS MER
