    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vision-based localization; automated vehicles;

    Sammanfattning : Automated driving can help solve the current and future problems of individualtransportation. Automated valet parking is a possible approach to help with overcrowded parking areas in cities and make electric vehicles more appealing. In an automated valet system, drivers are able to drop off their vehicle close to a parking area. LÄS MER

  3. 2. Dermal exposure determinants : a pesticide exposure assessment approach for developing countries

    Författare :Luis E Blanco Romero; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dermal exposure; pesticides; determinants of dermal exposure to pesticides; subsistence farmers; fluorescent tracer; visual scoring system;

    Sammanfattning : Background: We know little about the levels of exposure to pesticide in subsistence farmers mainly because of lack of easy to use and low cost pesticide exposure assessment methods. Aim: This thesis aimed to develop a semi-quantitative approach to assess dermal exposure to pesticides relevant for conditions in developing countries. LÄS MER

  4. 3. Dermal exposure to pesticides in Nicaragua : a qualitative and quantitative approach

    Författare :Aurora Aragón; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dermal exposure; developing country; pesticides; subsistence farmers; fluorescent tracer; visual scoring system; skin wipes; pesticide residues.;

    Sammanfattning : Background: Pesticide use continues to be a serious public health problem in developing countries, despite decades of safe pesticide use strategies. In Nicaragua, organophosphate insecticides, in particular chlorpyrifos and methamidophos are responsible for about half of the acute pesticide poisonings. LÄS MER

  5. 4. Aortic valve calcification : in vivo and ex vivo evaluation

    Författare :Mohamed Yousry; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Aortic valve calcification (AVC) or thickening is found in around one fifth of the general population between 65-75 years of age and increasingly thereafter. The process of aortic valve thickening and calcification is not only an aging (wear and tear) process of the valve leaflets. It is now considered to be closely related to atherosclerosis. LÄS MER
