  1. 1. Designing Intranets for Viability : Approaching Organizational Empowerment and Participation

    Författare :Christina Amcoff Nyström; Stig C Holmberg; Louise Yngström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Informatics; computer and systems science; Intranet design; Viable System Model; Empowerment; Democracy; Autonomy; Recursion; Viability; Participation; Informatik; data- och systemvetenskap; Informatics; computer and systems science; Informatik; data- och systemvetenskap; computer and systems sciences; data- och systemvetenskap;

    Sammanfattning : Intranets appeared in the mid-1990s and were perceived as the answer to the need for the integration of existing Information Systems into organisations. Despite the fact that there has been extensive research regarding implementation, development processes, policies standardisation vs. LÄS MER

  3. 2. Assessment of myocardial viability using magnetic resonance imaging

    Författare :Robert Jablonowski; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; myocardial infarction; hypertrophic cardiomyopathy; fibrosis; viability;

    Sammanfattning : Myocardial infarction (MI) following an acute coronary occlusion is a leading cause of morbidity and mortality. During revascularization, microemboli may complicate treatment and affect cardiac function. The long-term effects of microembolization are not fully elucidated. LÄS MER

  4. 3. Population viability analysis for plants : practical recommendations and applications

    Författare :Satu Ramula; Kari Lehtilä; Patrik Dinnétz; Esa Ranta; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; demography; matrix population models; population viability analysis; population growth rate; stochastic models; Biology; Biologi;

    Sammanfattning : Population viability analysis (PVA) is commonly used in conservation biology to predict population viability in terms of population growth rate and risk of extinction. However, large data requirements limit the use of PVA for many rare and threatened species. LÄS MER

  5. 4. Transesophageal Echocardiography in Patients Undergoing Elective Coronary Artery Bypass Surgery

    Författare :Ingrid Palmgren; Russell Anderson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; transesophageal echocardiography; low-dose dobutamine; viability; coronary artery bypass; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; anestesiologi; Anaesthesiology;

    Sammanfattning : Transesophageal echocardiography (TEE) has become a useful tool in monitoring the heart in patients during open-heart surgery. This study was undertaken to evaluate whether it is feasible to use TEE to assess left ventricular myocardial viability in anesthetized patients scheduled for coronary artery bypass grafting (CABG).

  7. 5. Characterisation of mammalian cell culture processes with NIR spectroscopy

    Författare :Per Sivertsson; KTH; []
    Nyckelord :near-infrared NIR spectroscopy; cell culture; mammalian cell culture; characterisation; glucose; lactate; ammonia; cell content; viability; multivariate analysis; principal component analysis PCA ; partial least squares regression PLS ; score plo;

    Sammanfattning : The importance of recombinant proteins produced by mammaliancell culture has increased dramatically due to the discoveriesin the field of recombinant biotechnology. Therefore,optimising and gaining process knowledge about cell culture hasalso gained in interest. LÄS MER
