  1. 1. Non-coagulating milk from Swedish Red Dairy Cattle : Influence of milk composition, physical properties and genetic parameters

    Författare :Kajsa Nilsson; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Non-coagulating milk; genetic parameter; milk composistion; heritability; protein profile; hydrolysation;

    Sammanfattning : Non-coagulating (NC) milk is unwanted in cheese production, as it lowers cheese yield and prolongs processing time. Less yield will lead to economic losses at the dairies. Even if NC milk has been found in several breeds, studies suggest that Swedish Red Dairy cattle (RDC) has a higher frequency of NC milk than most other breeds. LÄS MER

  3. 2. Biochemical and genetic markers after subarachnoid haemorrhage

    Författare :Ludvig Z Csajbok; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; subarachnoid haemorrhage; biochemical marker; genetic marker; outcome;

    Sammanfattning : ABSTRACT Background: Subarachnoid haemorrhage is a devastating disease with high morbidity and mortality despite novel treatment options are available. There are no established methods to measure the brain damage occurring due to the bleed and its complications and to predict early neurological outcome of the disease. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; programming; actuarial mathematics; Statistik; cytogenetics; Genetik; cytogenetik; Mathematics; Matematik; Statistics; operations research; Genetics; ROC curves; conditioning loci; optimal score functions; noncentrality parameter; cost adjusted relative efficiency; exponential tilting; importance sampling; Monte Carlo simulation; normal approximation; crossover rate; process maximum; analytical approximation; significance calculations; NPL score; conditional linkage analysis; two-locus linkage analysis; Allele sharing; aktuariematematik; operationsanalys; programmering; gene-gene interaction; composite hypotheses; genetic disease models; classes of score functions; nonparametric linkage analysis;

    Sammanfattning : In linkage analysis or, in a wider sense, gene mapping one searches for disease loci along a genome. This is done by observing so called marker genotypes (alleles) and phenotypes (affecteds/unaffecteds) of a pedigree set, i.e. LÄS MER

  5. 4. Genetic and environmental aspects of symptomatic gallstone disease

    Författare :Despina S Katsika; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Gallstone; Swedish Twin Registry; monozygotic; dizygotic; structural equation modeling; body mass index; alcohol; tobacco; ABCG8 D19 H; lith genes; association study;

    Sammanfattning : Gallstone disease (GD) represents a major healthcare problem. Gallstones are likely to result from a complex interaction of the environment and the effects of multiple undetermined genes. LÄS MER

  7. 5. On Parameter Identification for Better Predictions of Dam Behaviour

    Författare :Jasmina Toromanovic; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : Numerical modelling is often needed as a tool to predict the behaviour and assess the safety of dam structures. Embankment dam structures analyses are quite complex and potential failures are hazardous. Predictions of dam behaviour by numerical modelling rely on knowledge about the mechanical properties of the materials the dam is constructed with. LÄS MER
