  1. 1. Colonised Coasts : Aquaculture and Emergy Flows in the World System: Cases from Sri Lanka and the Philippines

    Författare :Daniel A. Bergquist; Lennart Strömquist; Clas Lindberg; Torbjörn Rydberg; Aida Aragao-Lagergren; Örjan Sjöberg; Uppsala universitet; []
    Nyckelord :Social and economic geography; Aquaculture; Capitalism; Socio-economic effects; Environmental effects; Benefit distribution; Sustainability; Sustainability assessment; Fairness; Development; Interdisciplinary; Transdisciplinary research; Geography; Emergy; World System Theory; General Systems Theory; Sustainable development; Sri Lanka; Philippines; Kulturgeografi;

    Sammanfattning : This thesis conceives aquaculture as a transfer of resources within and between different parts of the world system. It is argued that due to inappropriate human-nature interactions, resources tend to flow from the South to the North, as a process of coastal colonisation. LÄS MER

  3. 2. Integrated Communications and Thermal Management Systems for Microsystem-based Spacecraft : A Multifunctional Microsystem Approach

    Författare :Henrik Kratz; Anders Rydberg; Johan Köhler; Pelle Rangsten; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; nanospacecraft; MST; MEMS; silicon; communication; thermal management; antenna; paraffin; PCM; multifunctional; microsystems; Elektronik; Electronics; Elektronik;

    Sammanfattning : This thesis explores the potential of multifunctional silicon-based microsystems for advanced integrated nanospacecraft (AIN). Especially, multifunctional microsystems with the coexistant functions of communications and thermal management implemented in multilayer silicon stacks are approached with systems study. LÄS MER

  4. 3. Gravitational lensing as a probe of the first stars and galaxies

    Författare :Claes-Erik Rydberg; Erik Zackrisson; Lise Christensen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stars: Population III; first stars; Galaxies: high-redshift; Galaxies: Population III; dark ages; reionization; techniques: photometric; Astronomy; astronomi;

    Sammanfattning : This thesis investigates the potential for detection and identification of primordial stars, galaxies, and supernovae at high redshift.Simulations indicate that the first Population III stars should appear in minihalos of mass M = 105-106 Msol at z ≈ 10-30. LÄS MER

  5. 4. Depression among Swedish 70-year-olds - Sex differences from a gender perspective

    Författare :Therese Rydberg Sterner; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; depression; time trend; epidemiology; sex; gender; experiences; older adults;

    Sammanfattning : Depression is one of the leading causes of global burden of disease. Due to increased life expectancy, late-life depression is an escalating public health issue. The prevalence is reported to be almost twice as high among women compared to men. LÄS MER
