  1. 1. Aggrecan fragments as biomarkers in osteoarthritis

    Författare :Staffan Larsson; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protease; Aggrecan; osteoarthritis; proteoglycan; knee injury; biomarker; aggrecanase;

    Sammanfattning : Background: In osteoarthritis (OA) the balance of cartilage matrix synthesis and degradation is disturbed, resulting in a gradual destruction of the articular cartilage. Matrix components released into body fluids by proteolytic cleavage can be used as biomarkers of ongoing processes. LÄS MER

  2. 2. Lokal förankring och global räckvidd : En studie av teknikutveckling i svensk maskinindustri : [a study of technological development in the Swedish machinery industry]

    Författare :Staffan Larsson; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Agglomeration theory; technology; innovations; inter-firm relations; local embeddedness; firm performance; machinery industry; Kulturgeografi; Human geography; Kulturgeografi; kulturgeografi; Social and Economic Geography;

    Sammanfattning : Taking its point of departure in the proliferating literature on the localised nature of learning and innovation processes, this thesis sets out to answer the question whether locally embedded firms are more innovative than other firms. The thesis is based on a questionnaire that in the autumn of 1995 was sent to firms producing machinery. LÄS MER

  4. 4. New insights into lubricated tribological contacts

    Författare :Elin Larsson; Staffan Jacobson; Åsa Kassman Rudolphi; Jannica Heinrichs; Philip Shipway; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; friction; wear; lubrication; fuel additive; boric acid; tribofilm; transport; fuel efficiency; surface analysis; grease; LiX grease; PP grease; fretting; electrical contacts; cross section; copper; silver; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : The emissions of carbon dioxide, CO2, must rapidly be reduced to avoid severe climate change. Tribology-related solutions can be an important part in reducing these emissions. The aim of this thesis is to improve the fundamental knowledge in two tribology-related fields, both concerning lubrication, to enable such solutions in the future. LÄS MER

  5. 5. Minimal volume ventilation in lung injury : With special reference to apnea and buffer treatment

    Författare :Staffan Höstman; Anders Larsson; Hans Hjelmqvist; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VILI; THAM; buffers; apneic oxygenation; respiratory acidosis; hypercapnia; low volume ventilation; mechanical ventilation; ultra-protective ventilation; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : A fairly large portion of patients receiving surgical or intensive care will need mechanical ventilation at some point. The potential ventilator-induced lung injury (VILI) is thus of interest. One of the main causal factors in VILI is the cyclic energy shifts, i.e. LÄS MER
