  1. 16. On Multistage Analysis of Transonic Compressors: From Axisymmetric Throughflow Time-Marching to Unsteady Three-Dimensional Methods

    Författare :Stephane Baralon; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; shock; time-marching; deterministic; average-passage; multistage; fan; axisymmetric; 3D; unsteady; transonic; viscous; body force; stress; singularity; perturbation; throughflow; mixing-plane; modelling; finite-volume;

    Sammanfattning : A throughflow time-marching finite-volume solver, capable of computing viscous transonic multistage compressor flows with embedded shocks, is presented. The behavior of the blade model, based on the blade mean surface flow tangency condition, was investigated for transonic flows. LÄS MER

  3. 17. Underwater shock loaded sandwich structures

    Författare :Kjell Mäkinen; KTH; []
    Nyckelord :;

    Sammanfattning : The effects of underwater explosions on ships have beenstudied ever since it was realised that explosions under watercould be accomplished. In order to study the response of asandwich structure in water, exposed to an underwaterexplosion, we need to have knowledge about the whole chain ofevents, i.e. LÄS MER

  4. 18. Musculoskeletal disorders and whole-body vibration exposure among professional drivers of all-terrain vehicles

    Författare :Börje Rehn; Ronnie Lundström; Tohr Nilsson; Karin Harms Ringdahl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Whole-body vibration; Shock; Ergonomics; Epidemiology; Musculoskeletal; Driver; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; medicin; Medicine;

    Sammanfattning : Musculoskeletal disorders are common among professional driver groups. Ergonomic risk factors at work are often suggested as causative, aggravating or preserving. LÄS MER

  5. 19. The heart in the critically ill patient- an echocardiographic study

    Författare :Lill Bergenzaun; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Echocardiography; shock; left ventricular function; biomarkers; and outcome;

    Sammanfattning : The thesis describes aspects of left ventricular systolic and diastolic function examined with echocardiography in patients with systemic inflammation and shock. Background: Myocardial depression is a well-known complication in critically ill patients with shock. LÄS MER
