  1. 16. The Effect of Various Dopants on Diamond Growth : A Combined Experimental & Theoretical Approach

    Författare :Yiming Zou; Karin Larsson; Mats Boman; Petter Persson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diamond; Growth rate; HFCVD; Doping; Activation energy; Reaction order;

    Sammanfattning : Diamond is a unique material with many exceptional properties. It has therefore been proven to be an important material for many applications. Moreover, the introduction of dopant species into the gas phase during the CVD growth process has been shown to strongly influence not only the properties and morphology of diamond, but also the growth rate.

  2. 17. Quantitative analysis of tumor growth and response to therapy

    Författare :Esmaeil Mehrara; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tumor; growth; response; therapy; modeling; clinical;

    Sammanfattning : Modeling the natural growth of tumors is of value for evaluation of tumor progression and optimization of treatment strategies. However, modeling tumor growth based on clinical data is hampered by the limited data available, since therapy is in general initiated as early as possible after diagnosis. LÄS MER

  3. 18. Growth and Business Cycles -Swedish Manufacturing Industry 1952-2001

    Författare :Camilla Josephson; Lennart Schön; Deirdre Nansen MC Closkey; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ekonomisk och social historia; Social and economic history; Nutidshistoria från 1914 ; Contemporary history since 1914 ; Manufacturing industry; Institutional change; Knowledge accumulation; Opportunity costs; The cointegrated VAR model; Business cycles; Economic growth; TFP growth; Cyclical economics; Konjunkturteori; cykliska förlopp; Contemporary history;

    Sammanfattning : This study shows that the mechanisms behind knowledge accumulation and the sources of productivity growth differ from industry to industry depending on what is produced and what technology is used. Although it is apparent to most researchers in the field that the only way to explain long-run growth in output per capita is through technological progress and accumulation of knowledge that counteract the dampening effect of diminishing returns, we are still in the dark about how such mechanisms operate.

  4. 19. Cardiovascular effects of growth hormone. Studies in genetically engineered mice

    Författare :Irene Andersson; Göteborgs universitet; []
    Nyckelord :acromegaly; autonomic nervous system; cardiovascular disease; cardiac function; vascular function; growth hormone; heart rate variability; hypertension; insulin-like growth factor-1; transgenic mice;

    Sammanfattning : The general aim of this thesis was to enhance the understanding on the relationships between growth hormone (GH) and cardiovascular disease using genetically engineered mice. More specifically the effects of GH on blood pressure (BP), vascular and cardiac function, atherosclerosis and autonomic control of heart rate were studied. LÄS MER

  5. 20. Epitaxial growth of semiconductor nanowires

    Författare :Ann Persson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; materialteknik; nanowires; nanostructures; growth mechanism; Materiallära; Material technology; Halvledarfysik; Semiconductory physics; nanoelectronics; Au; VSS; VLS; surface diffusion; band gap engineering; InP; ternary system; GaAs; heterostructures; InAs; CBE; epitaxy;

    Sammanfattning : This thesis describes the results obtained from investigations carried out on epitaxially grown III-V semiconductor nanowires aimed at improving our understanding of and knowledge on the growth mechanism of nanowires. This is important to be able to control their growth, in order to make future applications possible. LÄS MER
