  1. 1. Growth and characterization of SiC and GaN

    Författare :Rafal Ciechonski; Erik Janzén; Sebastian Lourdudoss; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Sammanfattning : 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. LÄS MER

  2. 2. Studies on Poverty in Mongolia

    Författare :Bolor Naranhuu; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; 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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Mariam Elbornsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :growth hormone; growth hormone deficiency; growth hormone replacement; bone mineral density; body composition; muscle strength; elderly; cardiovascular risk factors; pituitary irradiation;

    Sammanfattning : 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. LÄS MER

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

    Författare :Luca Brandt; KTH; []
    Nyckelord :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.;

    Sammanfattning : 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.

  5. 5. Long-term effects of growth hormone replacement therapy in growth hormone deficient adults

    Författare :Galina Götherström; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :growth hormone; body composition; bone mass; bone density; muscle strength; lipids; glucose metabolism; adult onset GHD; childhood onset GHD; gender;

    Sammanfattning : Deficiency of growth hormone (GHD) in adults results in abnormal body composition, reduced bone mass and muscle strength, deteriorated cardiovascular risk factors. Short-term GH replacement reverses many of the symptoms associated with adult GHD. LÄS MER
