  1. 1. Deliberations on the impact of antibiotic contamination on dissemination of antibiotic resistance genes in aquatic environments

    Författare :Björn Berglund; Per-Eric Lindgren; Dan I. Andersson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The great success of antibiotics in treating bacterial infectious diseases has been hampered by the increasing prevalence of antibiotic resistant bacteria. Not only does antibiotic resistance threaten to increase the difficulty in treating bacterial infectious diseases, but it could also make medical procedures such as routine surgery and organ transplantations very dangerous to perform.

  3. 2. Measurement Variability Related to Insulin Secretion and Sensitivity : Assessment and Implications in Epidemiological Studies

    Författare :Lars Berglund; Björn Zethelius; Johan Bring; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Geriatrics and medical gerontology; Geriatrik och medicinsk gerontologi; Geriatrics; Geriatrik;

    Sammanfattning : There is a growing interest in random measurement variability of biological variables. In regression models, such variability of the predictors yields biased estimators of coefficients (regression dilution bias). LÄS MER

  4. 3. Chemical Communication and Mate Choice : Investigations into the Meaning of a Fruit Fly Pheromone

    Sammanfattning : Chemical signals are the most widely used form of sexual communication throughout the living world. However, there is in general little knowledge about what these signals actually communicate. The role of chemical signals, i.e. LÄS MER

  5. 4. Koszul duality for categories and a relative Sullivan-Wilkerson theorem

    Författare :Hadrien Espic; Gregory Arone; Alexander Berglund; Bjørn Dundas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Koszul duality; categories; Yoneda algebra; operads; dg modules; homotopy automorphisms; Sullivan-Wilkerson; arithmetic group; matematik; Mathematics;

    Sammanfattning : This PhD thesis consists in a collection of three papers on Koszul duality of categories and on an analogue of the Sullivan-Wilkerson theorem for relative CW-complexes.In Paper I, we define a general notion of Koszul dual in the context of a monoidal biclosed model category.

  7. 5. Arbetsmiljö och säkerhet : Praktikgemenskaper på könade byggarbetsplatser

    Författare :Maria Johansson; Lena Abrahamsson; Leif Berglund; Björn Samuelson; Lotta Dellve; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Human Work Sciences; Arbetsvetenskap;

    Sammanfattning : Trots att många insatser genomförs är fortfarande anställda på byggarbetsplatser överrepresenterade i arbetsskadestatistiken. Avhandlingens övergripande syfte är att bidra till kunskap om varför byggarbetsplatser fortsätter att drabbas av en hög andel arbetsskador. LÄS MER
