  1. 1. Driving rain tightness, intrusion rates and phenomenology of leakages in defects of façades: A new calculation algorithm

    Författare :Lars Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; façade details; rain resistance; window-wall interface; EN 12865; protrusion; deficiency; catch area; water flow; obstacle; fenestration; dam; driving rain; water leakage; leakage flow; hole;

    Sammanfattning : This thesis presents the driving rain tightness of façades with façade details as well as the water leakage flows that can be expected. Furthermore, it describes the key mechanisms for water leakage in defects in the outermost layer of external walls. LÄS MER

  3. 2. Mitigation of Pressure Pulsations in Axial turbine draft tube with jet injection or solid rod protrusion: A Numerical investigation

    Författare :Henrik Holmström; Cécile Münch-Alligné; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vortex rope mitigation; vortex rope; Strömningslära; Fluid Mechanics;

    Sammanfattning : The introduction of intermittent renewable energy sources, such as wind and solar power, to the power grid, demands some hydraulic turbines to operate at unfavorable operating conditions not initially designed for. Strong swirl develops at loads below the best efficiency point, (BEP) due to angle mismatch between the guide vanes and the fixed runner blades typical for Francis and Propeller turbines. LÄS MER

  5. 4. Assessment and Treatment of Impaired Insulin- Secretion and Action in Type 2 Diabetes

    Författare :Mozhgan Dorkhan; diabetes och endokrinologi Genomik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 diabetes; insulin secretion; glucagon test; insulin resistance; insulin glargine; insulin tolerance test; thiazolidinediones; natriuretic peptides; adiponectin; thyroid associated ophthalmopathy; proinsulin;

    Sammanfattning : Type 2 diabetes (T2D) is a disease characterised by varying degrees of defect in insulin secretion and insulin sensitivity and associated with increased morbidity and mortality. Optimal glycaemic control reduces the progression of diabetic complications. LÄS MER

  7. 5. Parastomal hernia : clinical studies on definitions and prevention

    Författare :Arthur Jänes; Leif Israelsson; Åke Öberg; Torbjörn Holm; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parastomal hernia; stoma complications; prosthetic mesh; mesh complications; sigmoid stoma; ileostomy; laparoscopic stoma; CT-scan; Surgery; Kirurgi; kirurgi; Surgery;

    Sammanfattning : The aims of the studies was to evaluate the short and long term effects on the development of parastomal hernia and stoma complications of a prophylactic prosthetic mesh placed in a sublay position at the index operation.  Also the purpose was to validate a definition of parastomal hernia at clinical examination and a method and a definition of parastomal hernia at CT-scan.
