  1. 1. Target zones : theory and evidence

    Författare :Mats Kinnwall; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Prisutveckling;

    Sammanfattning : In three papers we analyze the effects on different economic variables of implementing explicit target zones for economic policy. The first paper examines and tests two different models for devaluations in a target zone. LÄS MER

  3. 2. Infant and child mortality in Eritrea : levels, trends, and determinants

    Författare :Gebremariam Woldemicael; Basia Zaba; Stockholms universitet; []
    Nyckelord :demografi; Demography;

    Sammanfattning : This thesis has three main objectives: first, to estimate age-specific levels, age patterns and period trends in early mortality at national and sub-national levels in Eritrea; second, to investigate the major possible determinants of infant and child mortality; and third to discuss implications of the main findings for health policy and future research directions.The data used for this study come from the 1995 Eritrea Demographic and Health Survey of 5,469 households and 5,054 women in the reproductive age span.

  4. 3. Target and non-target effects of genetically modified trees

    Författare :Petter Axelsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Uncertainties of realized benefits and the potential for environmental effects of genetically modified (GM) trees may comprise an obstacle for an environmentally safe deployment and social acceptance of such products. Through a series of studies I explored target and non-target effects of GM trees in an objective to increase our knowledge of both benefits and environmental effects of these products. LÄS MER

  5. 4. Liquid-Jet-Target Microfocus X-Ray Sources : Electron Guns, Optics and Phase-Contrast Imaging

    Författare :Tomi Tuohimaa; Hans M. Hertz; Stephen Wilkins; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electron-impact; x-ray; brightness; liquid-jet-target; phase-contrast imaging; Engineering physics; Teknisk fysik;

    Sammanfattning : This Thesis describes the development of an electron-impact microfocus x-ray source and its application for phase-contrast imaging. The source is based on a novel, liquid-jet target concept. Stable and continuous operation can be achieved at substantially higher electron-beam power densities than conventional solid target based systems. LÄS MER

  7. 5. Building renovation processes towards low greenhouse gas emissions and energy use

    Författare :Stefan Olsson; Tove Malmqvist; Göran Finnveden; Dennis Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renovation processes; buildings; energy efficiency; greenhouse gas emissions; target levels;

    Sammanfattning : Buildings from the record year era are now 40 – 55 years old and in many cases in need of extensive renovation measures. This need for renovation could be seen as an opportunity to achieve overarching sustainability target levels and to perform renovation with a holistic approach. LÄS MER
