11. Early domestication? : Phenotypic alterations of Red Junglefowl selected for divergent fear of humans
Sammanfattning : Domestication is the process through which animals adapt to conditions provided by humans. The domesticated phenotype differs from wild ancestors in a number of traits relating to physiology, morphology and behaviour. LÄS MER
12. System studies of the use of industrial excess heat
Sammanfattning : Energy, materials, and by-products, can be exchanged between companies, having positive effects in the form of improved resource efficiency, environmental benefits, and economic gains. One such energy stream that can be exchanged is excess heat, that is, heat generated as a by-product during, for example, industrial production. LÄS MER
13. Nutritional and physicochemical characterisation of dietary fibre in wheat fractions
Sammanfattning : Dietary fibre is fermented in the colon to short-chain fatty acids (SCFAs), of which especially butyric and propionic acid may have health-promoting effects. One source of dietary fibre may be by-products from wheat, which are currently used as animal feed. LÄS MER
14. Collaborative development of resource efficient district heating in Sweden
Sammanfattning : An increased recovery of excess heat from industrial processes and thermal power generation could significantly reduce energy demands. Industrial excess heat-based district heating systems are generally considered resource efficient because they reduce the use of fossil fuels and the emissions of greenhouse gases. LÄS MER
15. Predicting the sound field from aeroacoustic sources on moving vehicles : Towards an improved urban environment
Sammanfattning : In a society where environmental noise is becoming a major health and economical concern, sound emissions are an increasingly critical design factor for vehicle manufacturers. With about a quarter of the European population living close to roads with heavy traffic, traffic noise in urban landscapes has to be addressed first. LÄS MER
