  2. 1. Evaluating effects of low concentrations of oil in marine benthic communities

    Author : Fredrik Lindgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PAHs; community response; microbial community; oil; meiofauna;

    Abstract : Large anthropogenic discharges of oil annually enter the marine environment, in the magnitude from large scale discharges to minor leakage, caused by ship collision accidents or seepage from urban areas. Possible detrimental environmental effects from these discharges differ, from acute lethal to chronic sub-lethal. READ MORE

  4. 2. Particulate Emissions Associated with Diesel Engine Oil Consumption

    Author : Petter Tornehed; Ulf Olofsson; Gordon E. Andrews; KTH; []
    Keywords : Lubrication oil; Particulate emission; Particulate matter PM ; Oil consumption; Diesel engine; Mechanical engineering; Maskinteknik;

    Abstract : Particulate emissions from diesel engines have been a key issue for diesel engine developers in recent decades. Their work has succeeded in reducing the exhaust particles from the combustion of fuel, which has led to increasing interest in the contribution of particulates from lubrication oil. READ MORE

  5. 3. Novel oil resistant cellulosic materials

    Author : Christian Aulin; Lars Wågberg; Derek Gray; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oleophobic; MFC; cellulose; oil resistant; contact angle; XPS; SEM; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : The aim of this study has been to prepare and characterise oil resistant cellulosic materials, ranging from model surfaces to papers and aerogels. The cellulosic materials were made oil resistant by chemical and topographic modifications, based on surface energy, surface roughness and barrier approaches. READ MORE

    Abstract : This thesis consists of four papers studying economic aspects of natural resource and environmental management in Namibia.Paper [I] analyses changes in Namibian energy use patterns between 1980 and 1998. READ MORE

  7. 5. On Low-Cycle Fatigue

    Author : Johan Tryding; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The experimental results presented confirm the anticipation that it is extremely important not to confuse the concept of 'static loading' with the one of 'monotonic loading'. In principle three different crack configurations were investigated in: edge-cracks, internal flaws and surface cracks. READ MORE
