  1. 1. Ethical aspects of radiation protection

    Author : Per Wikman-Svahn; John Cantwell; Gustaf Arrhenius; KTH; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Radiation; risk; ethics; Philosophy subjects; Filosofiämnen;

    Abstract : This aim of this thesis is to examine ethical aspects of radiation protection from ionizing radiation. Radiation protection is the professional field that deals with the protection of humans and the environment from the harmful effects of radiation. READ MORE

  2. 2. Biomarker discovery and assessment for prediction of kidney response after 177Lu-octreotate therapy

    Author : Emil Schüler; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PRRT; somatostatin; radionuclide therapy; 177Lu-octreotate; scintigraphy; renal function; toxicity; kidney response; radiation biology; microarray; molecular biomarkers; ionizing radiation; miRNA; proteomics; transcriptional response;

    Abstract : Patients suffering from neuroendocrine tumors are oftentimes presented with spread disease at the time of diagnosis. Therapy using somatostatin analogs is today the only potentially curative treatment option for these patients. READ MORE

  3. 3. Cancer Risk Assessment of Glycidol : Evaluation of a Multiplicative Risk Model for Genotoxic Compounds

    Author : Jenny Aasa; Margareta Törnqvist; Elaine M. Faustman; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; glycidol; 3-monochloropropane-1; 2-diol 3-MCPD ; genotoxicity; mutations; micronuclei; hemoglobin adducts; in vivo dose; multiplicative risk model; cancer risk assessment; human cancer risk; Environmental Chemistry; miljökemi;

    Abstract : Humans are exposed to chemical compounds in everyday life, both from the environment and from endogenous processes. Some compounds constitute a risk for cancer development. One such compound is glycidol, which is genotoxic and an animal carcinogen. It is the model compound of this work, partly due to its presence in food. READ MORE

  4. 4. Characterization of the MRI patient exposure environment and exposure assessment methods for magnetic fields in MRI scanners

    Author : Jennifer Frankel; Jonna Wilén; Anders Garpebring; Johan Olsrud; Peter Lundberg; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electromagnetic fields; exposure assessment; magnetic resonance imaging; switched gradient fields; radiofrequency fields; exposure metrics; radiofysik; radiation physics;

    Abstract : Magnetic resonance imaging (MRI) has become one of the most common imaging modalities available in modern medicine, and it is an indispensable diagnostic tool thanks to the unparalleled soft-tissue contrast and high image resolution. It is also a unique exposure environment consisting of a complex mix of magnetic fields. READ MORE

  5. 5. Modelling and Experimental Investigations on Thermal Radiation in Combustion Environments

    Author : Henrik Hofgren; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal radiation; Property model; SNB; WSGG; LBL; Planck; particle; fly-ash; soot; grate; furnace; combustion;

    Abstract : Thermal radiation is an important physical phenomenon in combustion environments. For the understanding of existing- and the design of new combustion environments computational modelling is a useful tool as it can describe the different transport phenomena. READ MORE
