  2. 2. Sickness Absence in Sweden : Its relation to Work, Health and Social Insurance Factors

    Författare :Lars-Gunnar Engström; Staffan Janson; Tor Eriksen; Gunnel Hensing; Karlstads universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sickness absence; return to work; work ability; work related factors; psycho-social work environment; health related factors; social insurance system factors; vocational rehabilitation; Public health science; Folkhälsovetenskap; Public Health Science; Folkhälsovetenskap;

    Sammanfattning : Background: The high levels of sickness absence and disability pensioning experienced during the 1990's and 2000's have become both socially as well as financially burdensome for society. Sickness absence implies a costly loss of production for society and large groups of individuals are risking to become marginalised on the labour market. LÄS MER

  3. 3. Early detection of major surgical postoperative complications evaluated by microdialysis

    Författare :Tal Hörer; Kjell Janson; Lars Norgren; Bengt Jeppsson; Örebro universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aortic occlusion balloon; anastomotic leakage; glycerol; intraabdominal hypertension; intraperitoneal microdialysis; intestinal ischemia; intraabdominal metabolism; lactate pyruvate ratio; postoperative complications; ruptured abdominal aortic anerusym; Surgery; Kirurgi;

    Sammanfattning : Major abdominal surgery may be followed by postoperative complications, especially in the elderly and patients with co morbidities as diabetes mellitus and obesity. Some of the most feared complications as anastomotic leakage, abdominal infections, abdominal compartment syndrome (ACS) and intestinal ischemia can lead to sepsis, systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS) with high morbidity and mortality.

  4. 4. Optimal and Hereditarily Optimal Realizations of Metric Spaces

    Författare :Alice Lesser; Svante Janson; Lars-Erik Persson; Anders Johansson; Vincent Moulton; Pierre Flener; Charles Semple; Uppsala universitet; []
    Nyckelord :Applied mathematics; optimal realization; hereditarily optimal realization; tight span; phylogenetic network; Buneman graph; split decomposition; T-theory; finite metric space; topological graph theory; discrete geometry; Tillämpad matematik;

    Sammanfattning : This PhD thesis, consisting of an introduction, four papers, and some supplementary results, studies the problem of finding an optimal realization of a given finite metric space: a weighted graph which preserves the metric's distances and has minimal total edge weight. This problem is known to be NP-hard, and solutions are not necessarily unique. LÄS MER
