  1. 1. Structural studies and design of Di-iron carboxylate proteins

    Författare :Martin Andersson; Martin Bollinger Jr; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : Di-iron carboxylate proteins perform a wide range of chemical reactions in the cell. These reactions often involve activation of dioxygen to generate highly oxidative species that can be used in catalysis. One member of the di-iron carboxylate family is the enzyme ribonucleotide reductase (RNR). LÄS MER

  3. 3. An experimental investigation of spur gear efficiency and temperature : A comparison between ground and superfinished surfaces

    Författare :Martin Andersson; Ulf Olofsson; Bengt-Göran Rosén; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gears; ground; superfinished; efficiency; temperature; running-in; dip lubrication; spray lubrication; Machine Design; Maskinkonstruktion;

    Sammanfattning : This thesis focuses on reliability when testing gear efficiency and on how gear mesh efficiency can be increased without detrimental effects on the gears. Test equipment commonly used in gear research was analysed to identify important parameters for gear efficiency testing. LÄS MER

  4. 4. Bending the Kuznets Curve - Wrenching and Levelling Forces during Agricultural Transformation in Taiwan and Chile

    Författare :Martin Andersson; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Chile; Taiwan; initial conditions; agricultural transformation; wrenching and levelling forces; the Kuznets Curve; Economic growth; income distribution; Social and economic history; Ekonomisk och social historia;

    Sammanfattning : What are the effects of growth on equality in a long-term perspective? What are the effects of different patterns of equality on subsequent growth? And why are these questions relevant for the understanding of economic development? These are the overriding questions posed in the dissertation. They are addressed in the context of long-term change from economic backwardness to modern economic growth by examining the processes of agricultural transformation of two successful growth achievers -- Taiwan and Chile.

  5. 5. Biological aspects of synovial fluid mediated aseptic prosthesis loosening

    Författare :Martin Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Aseptic loosening; synovial fluid; osteoblasts; bone resorption; IGF;

    Sammanfattning : Aseptic prosthesis loosening is the most common reason for late failure of total hip arthroplasties. Resorption of the peri-prosthetic bone, resulting in a loose prosthesis is characteristic for aseptic loosening. LÄS MER
