  1. 6. Multisensor arrays : for bioprocess monitoring

    Författare :Thomas Bachinger; Elmar Heinzle; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Bioprocess engineering, the technology that is focused on the exploitation of the metabolic potential of biological agents, has attracted growing interest throughout the past 50 years from both scientific and industrial communities. The products that have been brought to market range from pharmaceuticals and enzymes to food products and vitamins. LÄS MER

  3. 7. On Evaluation of Working Conditions aboard High-Performance Marine Craft

    Författare :Pahansen de Alwis; Karl Garme; Anders Rosén; Joakim Dahlman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed marine craft; human factors integration; whole-body vibration; epidemiology; musculoskeletal pain; fatigue; höghastighetsfartyg; human factors; HFI; helkroppsvibrationer; epidemiologi; muskuloskeletal smärta; utmattning; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : High-Performance Marine Craft (HPMC) is a complex system confronted by the stochastic nature of the waves challenging the safety of life at sea. The personnel aboard these craft are vulnerable to detrimental conditions, in fact, limiting the system’s performance evoking the significance of the Human Factors Integration (HFI) in the design and operation of these craft.

  4. 8. Evaluation of strategies to predict and improve early graft survival in clinical islet transplantation

    Författare :Torbjörn Lundgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Islets of Langerhans; clinical islet transplantation; cold storage; outcomes; PET CT; imaging; IBMIR;

    Sammanfattning : Transplantation of the islets of Langerhans as a treatment for type 1 diabetes (T1DM) is a procedure still under development. For the last decade it has been possible to obtain insulin independence by repeated infusions of islets. However, most patients must resume insulin therapy in 2-3 years. LÄS MER

  5. 9. Dupuytren´s Contracture : Features and Consequences

    Författare :Stephan Wilbrand; Lars Dahlin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Dupuytren´s contracture; epidemiology; outcome study; cohort; prognostic factors; immunohistochemistry; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Dupuytren's contracture (DC) is a fibromatous disease of the palmar fascia of unknown etiology. The present study was undertaken in order to assess pathophysiological mechanisms and consequences. In a cohort study of 2,375 patients operated for DC at the Department of Hand Surgery, Uppsala there was a male: female ratio of 5.9:1. LÄS MER

  7. 10. Cavitation Erosion Mechanisms in Cast Irons

    Författare :Marcio Freitas de Abreu; Stefan Jonsson; Jessica Elfsberg; Matevz Dular; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The research presented in this thesis investigated the mechanisms by which cavitation erosion damage develops in lamellar graphite iron (LGI) and austempered ductile irons (ADIs). This has been achieved by image sequences of surface erosion on test samples in tandem with weight change measurements. LÄS MER
