  1. 1. Assessing Sub-Lethal Impacts of Petroleum Compounds on Marine Benthic Systems

    Författare :Fredrik Lindgren; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; subletala effekter; mikrobiellt samhälle; meiofauna; petroleum; PAH; bildanalys;

    Sammanfattning : Petroleum and its different distillates commonly end up in the marine environment. One source of these additions is discharges originating from shipping activities; accidents, ship wrecks, operational spills etc. LÄS MER

  2. 2. Petroleum Production and Exploration : Approaching the End of Cheap Oil with Bottom-Up Modeling

    Författare :Kristofer Jakobsson; Kjell Aleklett; Roger Bezdek; Uppsala universitet; []

    Sammanfattning : The theme of this thesis is the depletion of petroleum (crude oil and natural gas). Are there reasons to be concerned about an ‘end of cheap oil’ in the near future? There is a lively debate regarding this issue. The debate is sometimes described as a clash of ‘concerned’ natural scientists and ‘unconcerned’ economists. LÄS MER

  3. 3. Phytoremediation of soil contaminated with petroleum hydrocarbons and trace elements

    Författare :Charlotte Marchand; Hogland William; Hijri Mohamed; Bramryd Torleif; Linnéuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Petroleum Hydrocarbon; Trace Elements; Gentle Soil Remediation Options; Polycyclic Aromatic Hydrocarbon; Respirometry; Ecopile; Bacteria; Fungi; Miljövetenskap; Environmental Science;

    Sammanfattning : The rapid urbanization and industrialization has led to an increase of disposal petroleum hydrocarbons (PHC) and trace elements (TE) into the environment. These pollutants are considered as the most toxic contaminants in the world due to their persistence in the environment, and the long range of toxicological effects for living beings. LÄS MER

  4. 4. Thermal Modelling of the Caledonian Basin, Scandinavia and a Northern North Sea Profile

    Författare :Jörgen Samuelsson; Chalmers University of Technology; []
    Nyckelord :petroleum; vitrinite reflectance; thermal maturation; flexural rigidity; heat flow; suppression; thermal conductivity; North West Shelf; Alum Shale;

    Sammanfattning : The reason for the registered high paleotemperatures of the Scandinavian Alum Shale was investigated by heat flow modelling constrained by vitrinite-like reflectance. The behaviour of the lithosphere under a load was modelled and the paleotemperatures were explained by burial of the Alum Shale in a foreland basin, developing during the Caledonian orogeny. LÄS MER

  5. 5. Västsvensk petroleumindustri 1945-2000 : etablering och tillväxt

    Författare :Kurt Johnsson; Chalmers University of Technology; []
    Nyckelord :HUMANIORA; HUMANITIES; technological systems; petroleum industry; fuel refinery; innovation; institution; industrial network; petrochemicals;

    Sammanfattning : The purpose of the study has been to describe and analyse the establishment and growth of the petroleum industry in western Sweden during the second half of the twentieth century. Empirical data shows that the development of refineries has in large part been governed by environmental changes where belonging to an international concern with large financial resources, and a determined investment in FoU in order to be at the forefront, has been advantageous.
