    Sammanfattning : Negative ions are of fundamental interest in atomic physics due to the enhanced importance of the electron correlation. In this thesis new spectroscopic methods have been developed and then applied to study the nature of atomic negative ions. LÄS MER

  3. 2. Facets of Gender : Analyses of the Family and the Labour Market

    Författare :Marie Evertsson; Jan O. Jonsson; Paula England; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Gender; housework; household work; gender equality; gender attitudes; dependence; labour market; children; family; on-the-job training; divorce; promotion; occupational change; division of work; Sociology; Sociologi;

    Sammanfattning : This thesis contains four different studies on the dynamics of gender in households and workplaces. The relationship between family life and work life is in focus, particularly in the paper on labour market outcomes after divorce.In the introductory chapter, the Swedish context is briefly described.

  4. 3. The Maximum Displacement for Linear Probing Hashing

    Författare :Niclas Petersson; Svante Janson; Guy Louchard; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Probabilistic analysis of algorithms; hashing; linear probing; negative dependence; Brownian motion.; MATHEMATICS; MATEMATIK;

    Sammanfattning : In this thesis we study the standard probabilistic model for hashing with linear probing. The main purpose is to determine the asymptotic distribution for the maximum displacement. Depending on the ratio between the number of items and the number of cells, there are several cases to consider. LÄS MER

  5. 4. Use and misuse of sedative drugs and related substances - Findings in the general population and in individuals with opioid dependence

    Författare :Tove Abrahamsson; Lund Psykiatri; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Substance use; Sedatives; Anxiolytics; Hypnotics; Prescription drug miuse; Benzodiazepines; Z-drugs; Pregabalin; Self-assessed health; Quality of life; Opioid dependence; Opiate maintenance treatment; Mortality;

    Sammanfattning : Background: Prescription sedatives are efficient in the treatment of anxiety and sleeping disorders, but are associated with a risk of misuse and dependence, as well as an increased risk of accidents, injuries and overdoses, both in the general population and especially in individuals with other substance misuse. The present thesis aims to investigate prescription sedative use and misuse in two kinds of samples - in the general population, with focus on its association with subjective health and quality life, and in the subpopulation of individuals with opioid dependence, with focus on treatment outcome in opioid maintenance treatment and mortality.

  7. 5. Gastric bypass : positive and negative health effects

    Författare :Olof Backman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Obesity is a major health problem worldwide. It is preventable in theory, but in practice no country has been able to stop the development of increasing obesity. The only available treatment with sufficient long-term effect on weight loss and comorbid diseases is surgery. LÄS MER
