  1. 1. Agrarian plant economy at Uppåkra and the surrounding area : Archaeobotanical studies of an Iron Age regional center

    Författare :Mikael Larsson; Arkeologi; []
    Nyckelord :HUMANIORA; HUMANITIES;

    Sammanfattning : Up until the late nineteenth and early twentieth century, and probably since the introduction of agriculture to Sweden, the social life, culture, traditions, building patterns and material culture would largely have been based on agricultural practices. And yet, in the archaeological record, agricultural aspects of social life remain elusive and little is known about the organization of farming and of the handling and distribution of food and other agricultural products, both within settlements and on a societal level.

  2. 2. Analysis and optimisation of energy and environmental performance of an integrated steel plant by process integration

    Författare :Mikael Larsson; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : The process industries stand for a substantial part of the energy used in Sweden. Industrial systems, such as an integrated steel plant, involve large interchange of energy between various processes and process streams. A major task for the steel industry is to minimize environmental impact, the consumption of energy and raw materials. LÄS MER

  3. 3. Process integration in the steel industry : possibilities to analyse energy use and environmental impacts for an integrated steel mill

    Författare :Mikael Larsson; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : There is a growing awareness of serious problems associated with the use of energy. These problems include local and global environmental degradation associated with energy use and depletion of resources. LÄS MER

  4. 4. Coke on Supported Palladium and Platinum Catalysts

    Författare :Mikael Larsson; Chalmers University of Technology; []
    Nyckelord :TPO; palladium; deactivation; coke; propane dehydrogenation; microbalance; vegetable oil hydrogenation; acetylene hydrogenation; catalysis; platinum;

    Sammanfattning : Catalyst deactivation by coke formation has been investigated in three heterogeneous catalytic processes, propane dehydrogenation, acetylene hydrogenation and hydrogenation of vegetable oil. Palladium and/or platinum supported on alumina were used as catalysts in all reactions. LÄS MER

  5. 5. Endogenous and exogenous factors affecting lipoprotein lipase activity

    Författare :Mikael Larsson; Gunilla Olivecrona; Aivar Lookene; Ira Tabas; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LPL; APOC1; APOC2; APOC3; ANGPTL4; enzyme inactivation; lipoprotein metabolism; triglycerides; fatty acids; hypertriglyceridemia; CVD; small molecule screening; structure-activity relationship; cardiovascular disease; hjärt- och kärlforskning;

    Sammanfattning : Individuals with high levels of plasma triglycerides are at high risk to develop cardiovascular disease (CVD), currently one of the major causes of death worldwide. Recent epidemiological studies show that loss-of-function mutations in the APOC3 gene lower plasma triglyceride levels and reduce the incidence of coronary artery disease. LÄS MER
