2. 1. Growth and characterization of SiC and GaN

   Author : Rafal Ciechonski; Erik Janzén; Sebastian Lourdudoss; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SiC; GaN; Deep level transient spectroscopy; Minority Carrier Transient Spectroscopy; Hall effect; Cathodoluminescence; Scanning electron microscopy; Atomic Force microscopy; sublimation growth; MOCVD; heterostructures; High Electron Mobility transistor; point defects; Material physics with surface physics; Materialfysik med ytfysik;

   Abstract : At present, focus of the SiC crystal growth development is on improving the crystalline quality without polytype inclusions, micropipes and the occurrence of extended defects. The purity of the grown material, as well as intentional doping must be well controlled and the processes understood. READ MORE

4. 2. Studies on Poverty in Mongolia

   Author : Bolor Naranhuu; Nationalekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik; Economics of development; Utvecklingsekonomi; economic systems; economic theory; econometrics; Economics; Mongolia; Transaction costs; Trade liberalization; Chronic poverty; Transient poverty; Inequality; Vulnerability; Poverty; Growth;

   Abstract : This thesis considers various aspects of the poverty in Mongolia, including estimations of the actual as well as future-looking poverty, its distributional and growth components, and selected policy impacts on poverty. Chapter two analyzes the inter-relationship between poverty, growth, and inequality in Mongolia, using Living Standard Measurement Survey (LSMS) for 1998 and 2002. READ MORE

5. 3. Long-term effects of growth hormone replacement in hypopituitary adults on body composition, bone mass and cardiovascular risk factors

   Author : Mariam Elbornsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; growth hormone; growth hormone deficiency; growth hormone replacement; bone mineral density; body composition; muscle strength; elderly; cardiovascular risk factors; pituitary irradiation;

   Abstract : Growth hormone (GH) deficient (GHD) adults have decreased bone mass and muscle strength, impaired body composition, disturbed serum lipid pattern and increased morbidity and mortality in cardiovascular and cerebrovascular diseases. GH replacement normalizes most of these aberrations within the first year of treatment. READ MORE

6. 4. Studies on Building Air Leakage -a transient pressurisation method, measurements and modelling

   Author : Björn Mattsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air change rate; Airtightness; CFD-simulations; moisture transport; air leakage; mould growth; cold attics; transient pressurisation;

   Abstract : Airtightness of the building envelope is a key factor for good performance of a building. The main part of this thesis deals with the exploration of a transient pressurisation method for air leakage measurements.In the transient method, an enclosure is pressurised to a desired pressure. The air flow into the enclosure is then stopped. READ MORE

7. 5. Study of generation, growth and breakdown of streamwise streaks in a Blasius boundary layer

   Author : Luca Brandt; KTH; []
   Keywords : Fluid mechanics; laminar-turbulent transition; boundary layer flow; transient growth; streamwise streaks; lift-up effect; receptivity; free-stream turbulence; streak instability; secondary instability; Direct Numerical Simulation.;

   Abstract : Transition from laminar to turbulent flow has beentraditionally studied in terms of exponentially growingeigensolutions to the linearized disturbance equations.However, experimental findings show that transition may occuralso for parameters combinations such that these eigensolutionsare damped.
