    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Populations of many large mammals and birds are increasing in many parts of Europe and North America. At the same time, the number of hunters is generally decreasing and an increasing proportion of people live in urban areas. LÄS MER

  3. 17. Room acoustics and cognitive load when listening to speech

    Författare :Robert Ljung; Anders Kjellberg; Staffan Hygge; Mats E. Nilsson; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Psychology; Teknisk psykologi;

    Sammanfattning : The present thesis investigated the effects of background noise or a long reverberation time in learning situations. All studies used spoken texts that were presented above the speech intelligibility threshold, but were degraded enough to make listening more effortful. LÄS MER

  4. 18. Socioeconomic inequalities in health : epidemiological studies of disease burden, mechanisms, and gender differences

    Författare :Rickard Ljung; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Burden of disease; disability-adjusted life years; socioeconomic factors; gender; misclassification; myocardial infarction; life course; risk accumulation; risk clustering;

    Sammanfattning : The overall aim of this thesis was to study inequalities in health, in particular, focusing on the risk of myocardial infarction and etiologic mechanisms from a life course perspective and on epidemiological measures and methodology. Paper I uses the Swedish Burden of Disease Study together with the Social Database managed by the Swedish National Board of Health and Welfare. LÄS MER

  5. 19. Fast Algorithms for Integral Equations and Least Squares Identification Problems

    Författare :Stefan Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fast algorithms; Integral equations; Least squares; Identification;

    Sammanfattning : This work is concerned with fast algorithms for integral equations and least squares identification problems.The presentation is divided into three parts. In the first part a fast algorithm for solving systems oflinear equations with a matrix that is alm ost Toeplitz is derived and applied to Fredholm integral equations with stationary kernels.

  7. 20. Nitric oxide in inflammatory bowel disease

    Författare :Tryggve Ljung; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The aim of this study was to study nitric oxide (NO) in inflammatory bowel disease (IBD) with a special reference to disease activity and disease location, in bolls an adult and a pediatric patient population, using rectal gas sampling. Furthermore, we investigated the cellular source of the measured NO as well as the relationship between the expression of inducible NO synthase (iNOS) and the proinflammatory TNF-alpha, IL-10 and INF-gamma.
