A large amount of our time is spent indoors in an artificial climate. To make the experience pleasant there are requirements on the ventilation and the heating system. At the present time the most common form of heating is a radiator system complemented with a ventilation system. A ceiling heating system with combined heating and ventilation can replace the two separated systems. The benefit with a ceiling heating solution is that it saves space since the radiator system is no longer needed.

Cardiac arrhythmias and heart diseases can result in a limited performance capacity which could lead to anxiety and depression. Objective: The aim of this study was to investigate the prevalence of symptoms of depression among patients with cardiac arrhythmias. The intention was also to explore differences between men and women in the occurrence of symptoms of depression. Furthermore, the prevalence of symptoms of depression among patients with cardiac arrhythmias was compared with a Swedish general population. Method: For two weeks MADRS-S, a self-rating scale for depression, were distributed at a medicine ward where patients with cardiac arrhythmias are treated, at a hospital in Sweden.

Swedish farmers have the possibility to be subsidized by EU rural development programme for grazing animals on pastures to promote the biodiversity of flora and fauna. The environmental remedy sometimes does not allow supplementary feed and at the same time the Swedish Animal Welfare Act and the Swedish Agricultural Board?s regulations for animal welfare and protection states that animals, in this case horses, shall be fed with food of good quality and adapted for the species. The regulations also state that they should have an individual feeding regime that enables them to maintain a normal body condition. The aim with this master thesis has been to investigate if it is possible to keep Gotland ponies on extensive pastures, during late spring and summer and still maintain animal welfare. The horses were assessed every fourth week using a welfare assessment protocol developed in line with the Welfare Quality® project (submitted, Viksten et al) where physical, behavioural and resourcebased parameters were observed. Twelve one-year old stallions of the breed Gotland ponies purchased from different breeders were used in the study.

The aim of this study was to investigate the social behaviour and time budget of breedingbulls kept at VikingGenetics, Falkenberg in Sweden when the staff was off duty. It was ofinterest to see if there was any difference between bulls housed in group pens and bullshoused in individual pens. It was also of interest to investigate if there was any differencein the behaviour between the dairy breeds Swedish Red (SR) and Swedish Holstein (SH).Sixteen bulls were used in this study. Eight bulls kept in individual pens and eight bullskept in group pens were used. The individually housed bulls had a social gate with widerbars where the bulls could but their head and neck through to have social contact with thebulls in its neighbouring pens.

 Den här studien utreder om en successiv marknadsanpassning har påbörjats efter reformeringen av hyressättningen på bostadshyresmarknaden 2011. Med hjälp av data från Hyresgästföreningen testas två hypoteser med hjälp av regressionsmetoden difference-in-difference. För det första om det har skett en inflationsjusterad ökning av hyrorna efter reformen som är större än i perioden före. För det andra om hyrorna har ökat mer i attraktiva kommuner än i mindre attraktiva kommuner. Slutligen undersöks om hyresmarknadens parter har ändrat sina attityder efter reformen.

It is mainly high levels of androstenone and skatole in adipose tissue that is the reason behind boar-taint, which is an unpleasant odor and taste from the meat of adult male boars. The purpose of this literature study is to provide an overview of current knowledge about the physioloical functioning of androstenone. There are several studies showing androstenone´s function as a pheromone, and that it is an important part of communication and mating behavior between pigs. Androstenone is produced in the testes of the boar and transported via the bloodstream to the salivary glands where it is excreted with the saliva. Sows sense the pheromone, not via the vomeronasal organ as previously considered, but via the olfactory mucosa.

This report will try to evaluate the use of rented concrete casting moulds, which are used to build walls and system of joists. The evaluation is only examining the economical aspects.The cost of using concrete casting moulds is a big part of the total production expenses. Therefore it is important that the calculated price not exceeds the final costs of the casting moulds. The calculated price is the price used in the process of making an offer.The evaluation consists of a comparison of the calculated price and the final costs for three building projects. It also evaluates the exploitation of the concrete casting moulds for each project.The report is made by Sven Gynne and Anders Alexandersson at School of Engineering, Jonkoping University, in cooperation with PEAB Jonkoping.

In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.

The purpose of this report was to investigate how the abiotic factors (temperature, pH, nutrients, oxygen levels and water content) would affect the decomposition of oil-contaminated soil and how a variance in structured soil would affect the decomposition-rate. A minor field-study was made and soil where structured in five different ways (one was a default pile and was used as a reference). The study took place over 137 days and three samples were taken (start, middle, end) and analyzed for aromatic and aliphatic compounds. The result of this study shows that there is a significant difference between all methods for the aliphatic compounds and no significant difference for the aromatic compounds. The abiotic factors that affect decomposition vary from organism to organism, depending on what type of environment it will function the best.

The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

Aim: Based on portfolio theory, which highlights diversification, and CSR, which describes the value of social and ethical responsibility of corporations, this study examines whether there is a difference in risk-adjusted performance between ethical and traditional mutual funds. Ethical funds are limited in their opportunities of diversification and should therefore be limited in their potential perfomance. On the other hand, a focus on social and ethical responsibility can be profitable.Method: The study uses a quantitative approach where we used 25 mutual fund in each category, ethical and conventional mutual funds. The mutual funds and their data has been obtained from www.morningstar.se and www.pensionmyndigheten.se. Historical performance between 2009-2013 were processed to obtain the Sharpe ratio and M2.
