    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The composition and properties of raw milk are important for the stability of dairy products, especially for products with long shelf-life, e.g. ultra-high temperature (UHT) treated milk. READ MORE

  4. 7. Sun exposure, prevalence and localization of common melanocytic naevi in Swedish children

    Author : Maria Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: The rapidly rising incidence rates of cutaneous malignant melanoma call for more effective prevention strategies. Melanoma susceptibility is associated with having many common melanocytic naevi. Having fair skin, blonde/ash-blonde hair and grey/blue/green eye colour are also joint risk factors for melanoma and naevi. READ MORE

  5. 8. The Aquaporins - Expression and Regulation of Water Channel Proteins

    Author : Maria Karlsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; immunocytochemistry; overexpression; phosphorylation; aquaporin; water channel; Växtbiokemi; Chemistry; Kemi;

    Abstract : Aquaporins are integral membrane proteins that function as water channels highly specific for water or as aquaglyceroporins permeable to water as well as small solutes such as glycerol and urea. The model plant Arabidopsis thaliana has 35 genes encoding aquaporin proteins. READ MORE

  6. 9. The MHC genes: variation and impact on life-history traits in house sparrwos

    Author : Maria Karlsson; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MHC-I; house sparrow; 454-amplicon sequencing; cDNA; functional clustering; trans-species evolution; nestling survival; mate-choice;

    Abstract : In birds the major histocompatibility complex (MHC) organization differs both among and within orders. Galliformes often have simple arrangements with few transcribed MHC genes whilst many songbirds (Passeriformes) have a complex arrangement with many MHC genes and also presence of pseudo-genes.

  7. 10. Estimators of semiparametric truncated and censored regression models

    Author : Maria Karlsson; Thomas Laitila; Göran Broström; Kenneth Carling; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; LTRC; consistency; asymtotic normality; bootstrap; interpurchase intervals; Statistik; Statistics; Statistik; Statistics; statistik;

    Abstract : This thesis contributes in several ways to the existing knowledge on estimation of truncated, censored, and left truncated right censored (LTRC) regression models. Three new semiparametric estimators are proposed, allowing for asymmetric error distributions. READ MORE
