  1. 1. Environmental and genetic factors in lung cancer : epidemiologocal and biomolecular studies focusing on nonsmokers

    Detta är en avhandling från Stockholm : Karolinska Institutet, false

    Författare :Fredrik Nyberg; Karolinska Institutet.; Karolinska Institutet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lung cancer; case-control study; smoking misclassification; exposure misclassification; validation; bias; nonsmoker; smoking; environmental tobacco smoke; ETS; diet; biomarker; glutathione S transferase; GSTM1; N-acetyl transferase; NAT2; hypoxanthine-guanine phosphoribosiyl transferase; hprt; DNA; adducts;

    Sammanfattning : Tobacco smoking is the major cause of lung cancer. Other risk factors include exposure to environmental tobacco smoke (ETS), dietarv habits and genetic factors. When studying such risk factors, confounding from smoking presents a pervasive methodological problem. LÄS MER

  2. 2. Structure and Motion Estimation in Rigid Body Perspective Dynamic Systems

    Detta är en avhandling från Stockholm : Karolinska Institutet, false

    Författare :Fredrik Nyberg; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Abstract This thesis concerns different aspects of recursive estimation of structure and motion in dynamic rigid body perspective systems, where the three-dimensional position of observed object feature points are expressed as states in a system of deterministic or stochastic differential equations describing the object motion, combined with a set of output equations in the form of two-dimensional perspective measurements obtained using a single camera. Firstly, a number of novel hybrid matching constraints are derived for the recovery of motion parameters in a rigid body perspective system where the measurements can be considered as arriving at closely spaced time instants.

  4. 4. The neural substrates of non-conscious working memory

    Detta är en avhandling från Umeå : Umeå University

    Författare :Fredrik Bergström; Johan Eriksson; Lars Nyberg; René Marois; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; non-conscious; working memory; neural substrates; visual perception; consciousness; functional magnetic resonance imaging fMRI ;

    Sammanfattning : Background: Despite our distinct impression to the contrary, we are only conscious of a fraction of all the neural activity underlying our thoughts and behavior. Most neural processes occur non-consciously, and in parallel with our conscious experience. LÄS MER

  5. 5. Le mouvement pentecôtiste - une communauté alternative au sud du Burundi 1935-1960

    Detta är en avhandling från Uppsala : Svenska Institutet för Missionsforskning / Swedish Institute of Mission Research

    Författare :Gunilla Nyberg Oskarsson; Carl-Fredrik Hallencreutz; Alf Tergel; Sigbert Axelsson; Josef Nsumbu; [2004]
    Nyckelord :HUMANIORA; HUMANITIES; Religion; Burundi; Bururi; Danish Baptist Mission; Gishiha; Kayogoro; Kiremba; Mugara; Pentecostalism; Revival; Rwanda General and Medical Mission; Swedish Free Mission; Swedish Pentecostal Movement; White Fathers; Religionsvetenskap Teologi; HUMANITIES and RELIGION Religion Theology; HUMANIORA och RELIGIONSVETENSKAP Religionsvetenskap Teologi;

    Sammanfattning : This thesis is a contribution to a hitherto neglected area of research: The African Pentecostal Churches, that do not belong to those called African Indigenous Churches (AICs). It is a case study from the perspective of southern Burundi, the periphery of the ancient kingdom. LÄS MER
