1. 1. Human body composition. Reference data and anthropometric equations. The metabolic syndrome and risk

   Författare :Ingrid Larsson; Göteborgs universitet; []
   Nyckelord :adults; anthropometry; atherosclerotic morbidity; body composition; body fat; cardiovascular disease; DEXA; dual energy x-ray absorptiometry; fat-free mass; FFM; humans; metabolic syndrome; morbidity; mortality; prediction equations; randomly selected sample; reference data; sagittal trunk diameter; TBK; total body potassium; waist circumference;

   Sammanfattning : The determination of body composition is a key to the understanding of the relation between obesity and disease. In order to evaluate body composition data, reference values are needed. Since methods with high validity and reproducibility are expensive and often time consuming, simpler techniques based on anthropometry are needed. LÄS MER

3. 2. Inhibition of Calcium and Zinc Absorption by Phytate in Man Methodological Studies and Hydrothermal Processing of Cereals to Improve Absorption

   Författare :Kerstin Fredlund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; barley; wheat; rye; 65Zn; oats; zinc absorption; whole grains; InsP6; hydrothermal processing; calcium absorption; rice; radionuclide technique; 47Ca; extrinsic labelling; phytate; hydrothermal treatment; myo-inositol; calcium retention; whole-body counting;

   Sammanfattning : A mathematical model based on measurements in a whole-body counter described the retention of calcium in the human body. It was shown that the relative retention of intravenous and orally administered 47Ca in all subjects (n = 10 - 11) were well described by fitting a simple function of time with two free parameters to a few whole-body measurements after day 6, when the unabsorbed calcium had been excreted.

4. 3. Radiation Detection Techniques for the Enhancement of Nuclear Safety

   Författare :Petty Bernitt Cartemo; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; whole body counting; depth profiling; voxel phantom; nuclear safeguards; Monte Carlo; orphan sources; radiation-induced material damage; pulsed beam; positron lifetime;

   Sammanfattning : The hazard originating from the use of nuclear materials in various areas of the society necessitates a number of experimental techniques for controlling and increasing the safety connected to radioactive substances.The following thesis is divided into two parts, representing different aspects to the detection of radiation effects.

5. 4. Methods for the Assessment of Long-Lived Radionuclides in Humans Resulting from Nuclear Activities or Accidents - Fission track analysis of trace-amounts 239Pu and a copper hexacyanoferrate kit for monitoring radiocaesium

   Författare :Lena Johansson; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caesium; plutonium; fission track analysis; urine; internal contamination; whole-body counting; Physics; Chernobyl; Fysik; Chemistry; Kemi;

   Sammanfattning : Fission track analysis (FTA) was developed to be applied to ultra-low levels of 239Pu in bioassay samples. An analytical protocol was established for the FTA processing. The detection limit was determined to 1.5 µBq and the calibration constant was 24 fission fragments per µBq 239Pu. LÄS MER

7. 5. Att leva med en kropp som värker : samtal med fysioterapeuten

   Författare :Maria Afrell; Carl Edvard Rudebeck; Mats Foldevi; Madeleine Abrandt Dahlgren; Kajsa Johansson; Amanda Lundvik Gyllensten; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Background and aim: Physiotherapists in primary care meet, assess and treat patients with long-standing benign musculoskeletal pain. As a clinical condition, long-standing pain is common but nonetheless it is quite complex. LÄS MER
