  1. 1. Ageing-associated changes of lysosomal compartment : implications on cellular functions

    Författare :Yuri Stroikin; Ulf Brunk; Alexei Terman; Karin Öllinger; Suresh Rattan; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Ageing; Apoptosis; Biological gabarge; Hormesis; Lipofuscin; Lysosome; Pathology; Patologi;

    Sammanfattning : The lysosomal compartment is a major site for intracellular degradation. Lysosomal degradation of the cell’s own constituents, so-called autophagy, not only provides a cell with nutrients, but also removes damaged and potentially dangerous endogenous structures, thus securing intracellular homeostasis.

  3. 2. Selected Problems in Financial Mathematics

    Författare :Erik Ekström; Johan Tysk; Svante Janson; Lane P. Hughston; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; American options; convexity; monotonicity in the volatility; robustness; optimal stopping; parabolic equations; free boundary problems; volatility; Russian options; game options; excessive functions; superreplication; smooth fit; Matematisk analys; Mathematical analysis; Analys;

    Sammanfattning : This thesis, consisting of six papers and a summary, studies the area of continuous time financial mathematics. A unifying theme for many of the problems studied is the implications of possible mis-specifications of models. Intimately connected with this question is, perhaps surprisingly, convexity properties of option prices. LÄS MER

  4. 3. Porträttbruk i Sverige 1840-1865 : En funktions- och interaktionsstudie

    Författare :Solfrid Söderlind; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Portrait Photography. Portrait Painting; Portrait Usage; 19th Century Sweden; Reception Theory; Art and Society; Pictorial Function; Portrayal and futeraction; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The purpose of this study is to illuminate the production and use of portraits in Sweden from 1840 to 1865. The initial year was when photography reached this country and the period ends with the crisis for portrait photography, in which an excessive number of practitioners wasreduced by bankruptcies.

  5. 4. Obstructive sleep apnea syndrome. Treatment outcome, psychiatric aspects, neuropsychology and quality of life

    Författare :Pia Dahlöf; Göteborgs universitet; []
    Nyckelord :obstructive sleep apnea syndrome; uvulopalatopharyngoplasty; oxygen desaturation index; psychiatric morbidity; depression; dexamethasone suppression test; verbal learning and recall; executive functions; quality of life; spouses; long-term follow-up;

    Sammanfattning : Background: Obstructive sleep apnea syndrome (OSAS) is characterized by snoring and apneas during sleep leading to oxygen desaturation, sleep fragmentation and excessive daytime sleepiness. Prior reports have indicated that psychiatric morbidity associated with sleep apnea might be reversed by intervention correcting the sleep related breathing disorder. LÄS MER
