  1. 1. Numerical Computations of Wakes Behind Wind Farms A tool to study Farm to Farm interaction

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ola Eriksson; Uppsala universitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wind turbine; Wind power; Wind farm; Wakes; Long distance wakes; Farm-Farm; Farm to farm interaction; Wind farm cluster; Large Eddy simulations; LES; Actuator disc method; ACD; CFD; Ellipsys3D; Prescribed boundary layer; PBL; Forced boundary layer; FBL; Meteorologi; Meteorology;

    Sammanfattning : More and larger wind farms are planned offshore. As the most suitable sites to build are limited these new wind farms will be constructed near to each other in so called wind farm clusters. Behind the wind turbines in these farms there is a disrupted flow of air called a wake that is characterized by reduced wind speed and increased turbulence. LÄS MER

  3. 3. Resisting feminised precarity Farm workers in post-strike Western Cape, South Africa

    Detta är en avhandling från Stockholm : Department of Ethnology, History of Religions and Gender Studies, Stockholm University

    Författare :Åsa Eriksson; Stockholms universitet.; [2018]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; gender; race ethnicity; precarity; feminisation of labour; resistance; intersectionality; farm work; South Africa; Sweden; genusvetenskap; Gender Studies;

    Sammanfattning : This dissertation seeks to contribute to the body of research on gender, neoliberal globalisation and work, and on the forms of resistance people engage in within a deeply unequal global order. It was devised in relation to developments during and after widespread, unprecedented labour and social protests among farm workers in export-oriented agriculture in the Western Cape, South Africa, 2012–2013.

  4. 4. Understanding crop and farm management

    Detta är en avhandling från Stockholm : Department of Ethnology, History of Religions and Gender Studies, Stockholm University

    Författare :Iman Raj Chongtham; Sveriges lantbruksuniversitet.; [2016]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Agriculture faces challenges in meeting rising demand for food, feed, fibre and fuel while coping with pressure from globalisation, limited natural resources and climate change. Farmers will choose management practices based on their goals and available resources and these practices will influence farm performance. LÄS MER

  5. 5. Early dietary exposure is associated with allergy development in the FARMFLORA birth cohort

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Karin Jonsson; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast milk; Allergy; Introduction of solids; Early life nutrition; Farm children; Dietary pattern; Serum; Dairy farm; Atopy; Fatty acid composition;

    Sammanfattning : The allergy prevalence is markedly low in children growing up on farms. Contact with livestock and consumption of unpasteurized milk has been associated with allergy protection, although other elements in the environment may contribute. LÄS MER
