… Another important aspect was to evaluate if the rubber floorings had a high enough durability to resist the normal wear in a farrowing pen. Concrete flooring is assumed to have a higher thermally conductive effect then rubber which can affect the sow’s chance to cool down …
… thoroughly investigated. This thesis project aims to investigate effects of high temperatures on engine oil degradation, with focus on the greatest degradation process: oxidation. To do this several engine runs have been performed on a 310 hp engine with EGR to see what happens …
… experimental plant. These laboratory-scale hydrolysis experiments showed that high temperature and high TS favours VFA-production. The results have also shown that four to five days retention time is suitable at a process temperature higher than 23°C, but also that the retention …

Energy price are on the way up to a high level that will not diminish in the future make us to focus more on the sustainable development for a better solution of residential houses. Passive house or low energy housing are one of the solution to make residential more environment …
… (SiC) as a base material in power electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature …
… has become an important pest in greenhouse cultivation all over the world. The high temperatures in the greenhouse are favourable for F. occidentalis. The damages from this pest can be found in flower buds or in growing points. When thrips are piercing the cells and sucking out …
… that dairy cows might suffer from heat stress when exposed to sun and high temperatures. The well-being of the cows is thereby reduced and the production may also decrease. In Sweden, no research has been done in the area and therefore it is now a clear need of improved …
… as an answer to environmental concerns regarding water consumption. Due to the high installation cost of traditional water meters, a new method of determining water consumption, without having to cut water pipes, is proposed. The proposed method distributes the total water …
High-performance equine athletes have an energy requirement that often reaches twice the maintenance requirement. Horses are grazers and adapted to a grass diet, and diets high in grains and concentrates are associated with digestive upsets and behavioural disorders. It could …
… in the existing systems so an upgrade is needed. The district heating has the highest temperature requirements at 100°C in the winter. To reach the relatively high temperatures required a hybrid heat pump proves to be a suitable solution due to a good Coefficient of Performance …
… shelter they can generally cope well with adverse weather conditions such as high or low ambient temperature, heavy rain or strong winds. In this study, the daytime shelter-seeking behaviour of three groups of horses housed outdoors was studied during the summer. The aim was to …
