  2. 1. Hadronic Structure Measurements of the Photon by DELPHI at LEP II

    Author : Andreas Nygren; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elementarpartikelfysik; DELPHI; LEP; VSAT; luminosity; two-photon physics; cross section; double tag; bhabha; background; structure function; kvantfältteori; quantum field theory; Elementary particle physics; Fysicumarkivet A:2001:Nygren;

    Abstract : This thesis is mainly an analysis of data taken by the VSAT detector in the DELPHI experiment at the LEP II collider at CERN. The analysis spans from 1998 to 2000, with a center of mass energy ranging from 189 to 206 GeV. READ MORE

  4. 2. CFD Modeling of an Alcohol-Diesel Direct-Injection Dual-Liquid-Fuel Engine using OpenFOAM

    Author : Andreas Nygren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable Fuels; Dual-Fuel Combustion; CFD; Spray Modeling;

    Abstract : Legislation for heavy duty combustion engines are becoming more stringent. To keep up with the legislation, new engine technology is required. Furthermore, renewable fuels can also be used together with new engine technology to further reduce emissions. READ MORE

  5. 3. Modeling of Spray Formation and Development in OpenFOAM with Application to Diesel and Alcohol Fuels

    Author : Andreas Nygren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; Spray Formation; Spray Modeling; VSB2;

    Abstract : Legislation with reagards to fuel emissions are becoming more stringent. This creates a need for improved engine concepts and fuels. This work is part of an ongoin project to create a concept for a direct injection dual fuel engine, which uses alcohol as main fuel and diesel as a pilot. READ MORE

  6. 4. Vasopressors and intestinal mucosal perfusion

    Author : Andreas Nygren; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : .... READ MORE

  7. 5. Vasopressors and intestinal mucosal perfusion. Studies in cardiac surgical and critically ill patients

    Author : Andreas Nygren; Göteborgs universitet; []
    Keywords : ;

    Abstract : During trauma, surgery and critically illness, splanchnic ischemia and reperfusion damage maythreaten the barrier function of the intestinal mucosa, leading to bacterial translocation, immuneactivation and subsequent development of systemic inflammatory response syndrome. Detection,prevention and treatment of intestinal mucosal hypoperfusion are therefore important forprevention of complications in critically ill patients. READ MORE
