  1. 1. ONSHORE WINDMILL FOUNDATIONS - Evaluation of new proposals

    Författare :Wael Mahmoud Mohamed Mohamed; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Onshore windmill foundations; Reuse of foundations; Active stabilisation systems; Conical footings;

    Sammanfattning : Windmill structures must withstand very high horizontal loading giving an extremely large overturning moment on the foundation. These structures have very low stability loads in comparison to the overturning loads. LÄS MER

  3. 2. Modelling driver steering and neuromuscular behaviour

    Författare :Ola Benderius; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reaching; neuromuscular behaviours; lateral control; driver models; Driver behaviours; active safety; autonomous vehicles;

    Sammanfattning : This thesis challenges the traditional view of treating steering behaviour as a tracking task, instead treating it as a reaching task. Here, reaching refers to a fundamental human behaviour with the the intriguing characteristic of having a linear relationship between maximum speed and distance, effectively making the movement time constant.

  4. 3. Decomposition of soil organic matter under a changing climate : a matter of efficiency?

    Författare :Tobias Bölscher; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Soil organic matter is the largest carbon (C) pool in the terrestrial C cycle, and soil CO₂ emissions surpass anthropogenic emissions from fossil fuel combustion by a factor of nine. Therefore, mechanisms controlling C stabilisation in soils and its feedback to climate change are widely debated. LÄS MER

  5. 4. Long-term properties of polyethylene films : efficiency of a natural antioxidant

    Författare :Clara Strandberg; Ann-Christine Albertsson; Jukka Seppälä; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer Technology; alfa-tocopherol; Polyethylene PE ; Thermal aging; Infrared Spectroscopy FT-IR ; Chemiluminescence CL ; Solid-phase microextraction SPME ; Chemistry; Kemi;

    Sammanfattning : There is a growing awareness of the risks of pollution in biological systems and one potential problem is the synthetic antioxidants, used for e.g. the stabilisation of polymeric materials. Natural antioxidants are an interesting alternative, if the high efficiency and thermal stability of the synthetic compounds can be reached. LÄS MER

  7. 5. Quantum Chemical Studies of Chemotherapeutic Drug Cisplatin : Activation and Binding to DNA

    Författare :Johan Raber; David van der Spoel; Paolo Carloni; Uppsala universitet; []
    Nyckelord :Quantum chemistry; cisplatin; quantum chemistry; DNA; density functional theory; activation; JM118; substitution reaction; Platinum; guanine; adenine; cytostatic drug; aquation; anation; activation; Kvantkemi;

    Sammanfattning : The serendipitous discovery of the potent cytotoxic properties of cisplatin brought about a revolution in the treatment of certain types of cancer, but almost fifty years later, there still remain unknown areas in the chemistry of cisplatin. There are questions regarding which form of the drug reaches its DNA target, or why certain DNA sequences are more preferred than others for reaction with cisplatin. LÄS MER
