  2. 11. Sleep disordered breathing at work : Cause and effects

    Author : Jan Ulfberg; Uppsala universitet; []
    Keywords : Medical sciences; Snoring; sleepiness; sleep apnea; epidemiology; organic solvents; work performance; occupational accidents; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : The recent discovery of obstructive sleep apnea syndrome (OSAS) as a prevalent disorder has highlightedthe fact that snoring is not just a harmless noise. Snoring and OSAS in the work milieu has hardly beeninvestigated, which makes it important to identify both risk factors and consequences in the work place. READ MORE

  5. 13. Analysis of Dispersion Effects in Unreplicated Factorial Designs

    Author : Kerstin Wiklander; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dispersion effects; location effects; two-level factorial experiment; fractional designs; Hadamard products; fractional designs;

    Abstract : Methods for estimating and testing hypotheses of dispersion effects in two-level unreplicated factorial designs are studied. Under a particular = normal model, some linear combinations of the response variables are constructed in order to make a simple inference. READ MORE

  6. 14. Matter and damping effects in neutrino mixing and oscillations

    Author : Mattias Blennow; Tommy Ohlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Neutrino oscillations; neutrino mixing; matter effects; damping effects; the day-night effect; solar neutrinos; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : This thesis is devoted to the study of neutrino physics in general and the study of neutrino mixing and oscillations in particular. In the standard model of particle physics, neutrinos are massless, and as a result, they do not mix or oscillate. READ MORE
