  2. 1. Sheet metal trimming dies – characterisation methods of geometry and surface topography and the influence on wear

    Author : Per Jonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finish milling; wear measurement; functional surface; trimming dies; scale-sensitive fractal analysis; surface roughness; polishing; surface characterisation; high strength steel; tool wear;

    Abstract : In recent years, the life cycle of car models has decreased from 7 to 5 years and the volume sizes are becoming shorter in the automotive industry. The increasing number of car models introduced to the market means that a fewer number of parts must pay the costs for the tool/die design and manufacturing. READ MORE

  4. 2. Numerical simulation of tube hydroforming : adaptive loading paths

    Author : Joakim Lundqvist; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The tube hydroforming process is still to be considered a new and advanced technique. The process has been adopted into several industries, e.g. automotive and aero. READ MORE

  5. 3. Cardiac arrest – prognostic biomarkers and aspects of shock

    Author : Martin Annborn; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac arrest; shock; outcome; prognostication; post cardiac arrest syndrome; hypothermia;

    Abstract : Background: Some improvement has been seen in survival after cardiac arrest but the outcome is still poor and 50-70% of patients do not survive despite successful return of spontaneous circulation (ROSC). The cause of death is multifactorial. The majority of patients die from brain injury, but up to 35% die as a result of circulatory failure. READ MORE

  6. 4. The diagnostic performance of prostate-specific antigen (PSA) in early detection of prostate cancer : considerations of sensitivity, specificity, lead-time and survival

    Author : Magnus Törnblom; Karolinska Institutet; Karolinska Institutet; []
    Keywords : PSA; free PSA; prostate cancer; sensitivity; specificity; lead-time; survival; epidemiology;

    Abstract : Background: Prostate cancer (PC) is the most common form of cancer, as well as the single major cause of cancer-related mortality among Swedish males. Recent reports indicate that screening of the serum levels of prostate-specific antigen (PSA) in asymptomatic men may result in decreases in both the incidence of metastatic disease and PC-specific mortality.
