  1. 21. Who died, where, when and why? : an investigation of HIV-related mortality in rural South Africa

    Författare :Paul Mee; Peter Byass; Mark A Collinson; Sangeetha Madhavan; Frank Tanser; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV; AIDS; Mortality; Determinants; Risk Factor; Spatial Epidemiology; Structural Determinant; Antiretroviral Therapy; Healthcare Access; South Africa; Sub-Saharan Africa; Traditional Medical Practitioner; Traditional Medicine; Tuberculosis; Health and Demographic Surveillance System; Global Health; Population Health; Epidemiology; Epidemiology; epidemiologi;

    Sammanfattning : BackgroundSouth Africa has experienced the most severe consequences of the HIV/AIDS pandemic. Every community has been affected in some way, many experiencing huge increases in mortality,particularly before antiretroviral therapies (ART) were readily available. LÄS MER

  3. 22. Polybrominated diphenylethers in the environment - Local and long range transport

    Författare :Arnout ter Schure; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Substance Flow Analysis; Spatial Variation; Sources; PCB; PBDE; Latitude; Global Fractionation; Frogs; Deposition; Atmosphere; Baltic Sea; Ekologi; Temperature; Washout ratio; Ecology;

    Sammanfattning : I have studied the sources, long range transport, and rates of flow of polybrominated diphenyl ethers (PBDEs), from the technosphere to the Baltic ecosystems. PBDEs are mainly used in polymers, which are applied in electrical equipment to prevent overheating or flashover and are produced in large quantities. LÄS MER

  4. 23. Method development for the analysis of protein interactions

    Författare :Despoina Kermpatsou; Ola Söderberg; Maréne Landström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in situ; proximity ligation assay PLA ; strand displacement; proximity-dependent initiation of hybridisation chain reaction proxHCR ; protein complexes; rolling circle amplification RCA ; MolBoolean; vitamin D; 1; 25D3-MARRS receptor; PDIA3; ERp57; CYP24A1; c-Myc; prostate cancer; Molekylär cellbiologi; Molecular Cellbiology; Molekylär medicin; Molecular Medicine;

    Sammanfattning : Biological processes take place through interactions between macromolecules, such as nucleic acids and proteins. It is, therefore, fundamental to understand the functions of proteins and how they form complexes in order to carry out their role. LÄS MER

  5. 24. Mapping social-ecological systems and human well-being : A spatial exploration of the links between people and the environment in South Africa

    Författare :Maike Hamann; Reinette Biggs; Gretchen Daily; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Social-ecological; systems; ecosystem services; bundles; human well-being; mapping; South Africa; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : It has become increasingly clear that dealing with present day environmental crises requires a holistic view that takes into account the interactions of social and ecological factors across multiple spatial and temporal scales. An example of where this new paradigm is being operationalized is the study of social-ecological systems. LÄS MER

  7. 25. An Experimental Study of Reynolds Stress Closures in Shear Free and Weakly Sheared Turbulence

    Författare :Dag Aronson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; turbulence modelling; dissipation measurements; Reynolds stress closures; isotropic turbulence; anisotropic dissipation rate tensor; hot-wire anemometry; wall proximity effects; pressure strain rate correlations;

    Sammanfattning : The objective of this thesis work is to obtain data enabling evaluation of closure hypotheses used in the Reynolds stress transport (RST) equations. Special attention has been devoted to studies of flow fields with shear free and weakly sheared turbulence. LÄS MER
