1. 11. Nutrition and health in 4-year-olds in a Swedish well-educated urban community

   Författare :Malin Garemo; Göteborgs universitet; []
   Nyckelord :composition; food habits; HOMA-index; preschool children; socio-economy;

   Sammanfattning : Background: Recent data about nutrition in Swedish preschool children is rare. During the latest decades the increased prevalence of welfare diseases have become an important issue in the general health work and it is desirable to be able to identify risk factors early in life.

3. 12. Microbial Community Assembly during Aerobic Granulation

   Författare :Raquel Liebana; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerobic granular sludge; granulation; washout dynamics; membrane bioreactors; sequencing batch reactors; fluorescence in-situ hybridization; microbial community dynamics; reproducibility;

   Sammanfattning : Environmental deterioration together with the increasingly restrictive legislation of water quality standards have led to a demand for compact, efficient and less energy consuming technologies for wastewater treatment. Aerobic granular membrane bioreactors (AGMBRs) combine the advantages of aerobic granular sludge and membrane filtration. LÄS MER

4. 13. Dietary Fatty Acids, Body Composition and Ectopic Fat : Results from Overfeeding Studies in Humans

   Författare :Fredrik Rosqvist; Ulf Risérus; Tommy Cederholm; Ian Macdonald; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Linoleic acid; Palmitic acid; SFA; PUFA; Fatty acids; Body composition; Liver fat; Ectopic fat; Adipose tissue; Medicinsk vetenskap; Medical Science;

   Sammanfattning : The aim of this thesis was to investigate the effects of dietary fatty acids on body composition and ectopic fat in humans, with emphasis on the role of the omega-6 polyunsaturated fatty acid (PUFA) linoleic acid (18:2n-6) and the saturated fatty acid (SFA) palmitic acid (16:0). The overall hypothesis was that linoleic acid would be beneficial compared with palmitic acid during overfeeding, as previously indicated in animals. LÄS MER

5. 14. Studies on nutrition, body composition and bone mineralization in healthy 8-yr-olds in an urban Swedish community

   Författare :Susanne Eriksson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; body composition; bone mineralization; dual energy x-ray absorptiometry; healthy; lipids; metabolic markers; overweight; physical activity;

   Sammanfattning : Background: The incidence of welfare diseases including overweight in childhood is increasing worldwide. The results from a study of healthy pre-school children showed that in a population with well educated parents 17% of the children were overweight or obese at the age of 4 years. LÄS MER

7. 15. Bacterial Activity and Community Composition in the Rhizosphere. Influence of plant species, root age, nitrogen addition and mycorrhizal status

   Författare :Katarina Söderberg; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CLPP; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Biolog; PLFA; mycorrhizal status; nitrogen addition; along roots; plant species; root age; thymidine and leucine incorporation; bacterial composition; Rhizosphere; bacterial activity;

   Sammanfattning : Microbial activity in soil is generally assumed to be limited by carbon availability. The soil closest to roots, the rhizosphere, is therefore a zone of high microbial activity due to carbon containing substances released by the root. In this work short-term effects in the rhizosphere have been the subject of investigation. LÄS MER
