2. 1. Irradiation of members of the general public from radioactive caesium following the Chernobyl reactor accident. Field studies in a highly contaminated area in the Bryansk region, Russia

   Author : Charlotte Thornberg; Malmö Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; body burden; Effective dose; Cs-137; urinary excretion; Cs-134; biological half-time; Chernobyl; breast milk; Medicine human and vertebrates ; internal irradiation; external irradiation; TLD; Clinical physics; radiology; medical instrumentation; tomography; Medicin människa och djur ; Physics; Fysik;

   Abstract : From 1990 to 1998, estimations of the effective dose from external as well as internal irradiation from 137Cs and 134Cs were carried out for inhabitants in rural villages in the Bryansk region, Russia, highly contaminated due to the Chernobyl accident in 1986. The villages were situated about 180 km from the Chernobyl power plant and the deposition of 137Cs was in the range 0. READ MORE

4. 2. Predicting Normal Tissue Complications after External Beam Radiation Therapy

   Author : Caroline Olsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NTCP; fractionation effects; radiobiological modelling; pubic bone pain;

   Abstract : Although modern external beam radiation (EBRT) therapy has the ability to conform the dose tightly around the volume to be treated, unwanted irradiation to surrounding normal tissue is still a problem. The probability of a side effect arising in normal tissue after EBRT is commonly modelled by an s-shaped dose-volume response curve where dose or volume are plotted against response (i. READ MORE

5. 3. Patient Outcomes after Radiotherapy of Prostate Cancer. Impact of Absorbed Dose and Treated Volume

   Author : Elisabeth Rasmusson; LUCC: Lunds universitets cancercentrum; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer diagnosis; radiotherapy; brachytherapy; external beam; Dose- response; side effects; erectile dysfunction; lymphedema; hip osteoarthritis; Fractionation;

   Abstract : Abstract Backgound Prostate cancer is the most common form of cancer in men in Sweden. Radiotherapy, including external beam radiation therapy (EBRT) and brachytherapy (BT), is important treatment alternatives to surgery and active surveillance. READ MORE

6. 4. Effect of metal ion irradiation on hard coating synthesis by physical vapor deposition

   Author : Tun-Wei Hsu; Magnus Odén; Grzegorz Greczynski; Sven Ulrich; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The aim of this thesis is to understand and control how the ions in the plasma influence the film growth during thin film deposition processes. Two physical vapor deposition (PVD) techniques are investigated, namely magnetron sputtering and cathodic arc evaporation. READ MORE

7. 5. Toward Energy-efficient Physical Vapor Deposition : Routes for Replacing Substrate Heating during Magnetron Sputtering by Employing Metal Ion Irradiation

   Author : Xiao Li; Grzegorz Greczynski; Ivan Petrov; Lars Hultman; Jyh-Wei Lee; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PVD; Magnetron sputtering; Thin films; HiPIMS; TiAlN; Energy efficiency;

   Abstract : In this Thesis, magnetron sputtering is perfected as an environmental-friendly deposition technique. I performed systematic studies of a novel approach - hybrid high-power impulse and dc magnetron co-sputtering (HiPIMS/DCMS) with metal-ion-synchronized substrate bias pulses. READ MORE
