  1. 1. Arsenic accumulation in plants for food and phytoremediation : Influence by external factors

    Författare :Claes Bergqvist; Maria Greger; Sylvia Lindberg; Lena Ma; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arsenic; accumulation; availability; distribution; habitat; phy-toremediation; rhizosphere; redox potential; speciation; Plant Physiology; växtfysiologi;

    Sammanfattning : Arsenic (As) appears in the environment as various As species, which may vary in plant uptake and toxicity. Moreover, As exposure may vary between habitat due to availability and speciation, both of which are influenced by redox potential. To decrease As uptake, addition of silicate may be a tool. LÄS MER

  4. 3. Radiosensitivity in lung cancer with focus on p53

    Författare :Michael Bergqvist; Claes Mercke; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Lung cancer; comet assay; p53; cDNA; p53 antibodies; Lungcancer; Komet metoden; p53 antikroppar; Onkologi; Oncology; Onkologi; Oncology; onkologi;

    Sammanfattning : In Sweden approximately 2800 new lung cancer patients are diagnosed every year. Radiotherapy is used with curative intention in certain groups of patients. The aim of this thesis is to study the basis of differences in radioresistance and the possibility to predict response to radiotherapy. LÄS MER

  5. 4. On methods of measuring magnetic properties of power transformers

    Författare :Claes Carrander; Göran Engdahl; Anders Bergqvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; No-load; magnetizing current; losses; diagnostics; delta; three-phase; power transformer; magnetic core; electrical steel; measurements; simulation; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The core of a power transformer can weigh hundreds of tons, and represents a significant part of the total ownership cost of the transformer, in terms of both the construction cost and of the monetary cost of losses. It is therefore desirable to have a method of diagnosing the core to ensure optimal performance, and to enable the operator to plan repairs of damaged or defective cores. LÄS MER

  7. 5. Predictive Factors in Esophageal Carcinoma

    Författare :Martin Dreilich; Michael Bergqvist; Anders Larsson; Daniel Brattström; Gunnar Wagenius; Claes Mercke; Uppsala universitet; []
    Nyckelord :Oncology; Esophageal carcinoma; Survival; Prognosis; Angiogenesis; HER-2; Telomerase; FMCA; HPV; Onkologi;

    Sammanfattning : Esophageal carcinoma is a malignancy with a poor prognosis and is the sixth cause of cancer related death worldwide. In Sweden approximately 400 new cases are diagnosed every year. The aim of this present thesis was to investigate predictive factors for esophageal carcinoma patients. LÄS MER
