  1. 21. Living in a Variable Environment : Reproductive Decisions in Wild Bird Populations

    Författare :Mårten B. Hjernquist; Lars Gustafsson; Marcel Visser; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; evolutionary ecology; competition; sex allocation; paternity; EPP; inadvertent social information; migration; breeding density; territory quality; territory availability; great tit; blue tit; Ficedula albicollis; Biology; Biologi; Animal Ecology; zooekologi;

    Sammanfattning : In nature, environments are often variable and heterogeneous influencing ecological and evolutionary processes. This thesis focus on how animals interact with their environment and how that affects the reproductive decisions they make. LÄS MER

  3. 22. Oral health and cardiovascular disease

    Författare :Anders Holmlund; Lars Lind; Ulf. H Lerner; Anders Gustafsson; Uppsala universitet; []
    Nyckelord :Medicine; Oral health; periodontal disease; number of teeth; cardiovascular disease; mortality; Medicin;

    Sammanfattning : In the past two decades studies have indicated that oral health might be associated with the prevalence for cardiovascular disease (CVD), although the biological link still remains unknown. Bacteria and inflammatory mediators causing periodontal disease have also been suggested to influence the progression of atherosclerosis. LÄS MER

  4. 23. Ribonucleotide reductase and DNA damage

    Författare :Pelle Håkansson; Lars Thelander; Claes Gustafsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ribonucleotide reductase; DNA damage; dNTP pools; Medical cell biology; Medicinsk cellbiologi;

    Sammanfattning : A prerequisite for a multicellular organism to survive is the ability to correctly replicate and repair DNA while minimizing the number of heritable mutations. To achieve this, cells need a balanced supply of deoxyribonucleoside triphosphates (dNTPs), the precursors for DNA synthesis. LÄS MER

  5. 24. Low Power and Low complexity Constant Multiplication using Serial Arithmetic

    Författare :Kenny Johansson; Lars Wanhammar; Oscar Gustafsson; Süleyman Demirsoy; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filters; Computer arithmetic; Multiplication; Addition; Low power; Switching activity; Electronics; Elektronik;

    Sammanfattning : The main issue in this thesis is to minimize the energy consumption per operation for the arithmetic parts of DSP circuits, such as digital filters. More specific, the focus is on single- and multiple-constant multiplication using serial arithmetic. The possibility to reduce the complexity and energy consumption is investigated. LÄS MER

  7. 25. Low Power and Low Complexity Shift-and-Add Based Computations

    Författare :Kenny Johansson; Oscar Gustafsson; Lars Wanhammar; Izzet Kale; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filters; Function approximation; Digital circuits; Computer arithmetic; Constant multiplication; Addition; Low power; Switching activity estimation; Electronics; Elektronik;

    Sammanfattning : The main issue in this thesis is to minimize the energy consumption per operation for the arithmetic parts of DSP circuits, such as digital filters. More specific, the focus is on single- and multiple-constant multiplications, which are realized using shift-and-add based computations. The possibilities to reduce the complexity, i.e. LÄS MER
