  1. 1. Electropermeabilization in Experimental Tumour Treatment: Dosimetry and Tissue Effects

    Detta är en avhandling från Department of Radiation Physics, Lund university

    Författare :Per Engström; Lund University.; Lunds universitet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; liver; electroporation; ischemia; Electropermeabilization; ECT; Tumor; 111-In-BLMC; 99m-Tc-DTPA; glioma; rat; electric pulses; Impedance spectrometry; treatment; Physics; Fysik;

    Sammanfattning : Short, electric high-voltage pulses can be used to transiently increase the permeability of cell membranes without significant loss of cell viability. During this period of time, extracellular and normally non-permeant, molecules are accessed the cytoplasm and the cell nucleus. LÄS MER

  3. 3. Optimal Taxation in Search Equilibrium

    Detta är en avhandling från Uppsala : Nationalekonomiska institutionen

    Författare :Per Engström; Uppsala universitet.; [2003]

  4. 4. Cadmium as a risk factor for osteoporosis and fractures in women

    Detta är en avhandling från Stockholm : Karolinska Institutet, Institute of Environmental Medicine

    Författare :Annette Engström; Karolinska Institutet.; Karolinska Institutet.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cadmium is toxic and accumulates in the body, particularly in the kidneys. Cereals, vegetables and potatoes are the main sources of exposure, besides tobacco smoking. The critical effect of cadmium is considered to be renal damage. Massive exposure is known to cause osteomalacia and osteoporosis with multiple fractures. LÄS MER

  5. 5. Nitrogen dynamics in crop sequences with winter oilseed rape and winter wheat

    Detta är en avhandling från Stockholm : Karolinska Institutet, Institute of Environmental Medicine

    Författare :Lena Engström; Sveriges lantbruksuniversitet.; [2010]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : With the aim of improving fertiliser nitrogen (N) strategies and reducing N leaching, seasonal changes in soil N supply in crop sequences with winter wheat after winter oilseed rape were examined through field experiments. Break crop effects on wheat after oilseed rape, compared with after peas and oats, were determined as regards residual N, yield and optimum N rate (Opt-N). LÄS MER
