A reward cycle for investigating the emotional status in animals has been developed and it requires that animals go through three main phases, i.e. anticipation, consumption and relaxation. The reward cycle has not been tested previously for access to play in pigs. Therefore, the aim of this Master thesis was to investigate if growing pigs showed more behaviours indicative of excitement than pigs that were not allowed to play, performed play in a play arena and showed more behaviours indicative of relaxation after play when they were back to their home pen than pigs that were in their home pen the whole time. Forty undocked piglets (10 litters of Specific Pathogen Free half pure-bred Yorkshire and half hybrids of Yorkshire x Landrace balanced for breed between two treatments were used.

The study aims to reduce energy consumption in apartment buildings where individual metering and charging of heat is applied. The aim is to develop planning and design for individual metering and charging in apartment buildings.The study is based on literature review, interviews and case study that include analysis of existing documents. Interviews were carried out with the property developer and the involved consultants who planned the apartment building Yasuragi. To investigate the differences the condominium association has noted in heat consumption between flats, the debit values of the heat were used to discern which houses that were furthest from the average consumption. On these flats there were temperature measurements and thermal photo shoots made for discriminating behavior and possible construction techniques which could be the explanation for the heat spread.Boverket shows that the consumption of heat can be reduced by 10-20% after insertion of individual metering and charging in an apartment block.

The great debate topic in media and among real estate agents in spring 2011 wasspecially reduced prices. Specially reduced prices means that a property is advertised at a considerably lower price than the evaluated current market value of the property. This is to attract more bidders in a potential bidding. It is in this case not completely established by law what is meant by considerably lower price, why this concept is difficult to interpret. Real estate agents got lot of criticism due to the output prices which were too low compared to the final prices.

This report describes the work and the results found when comparing three different 3d modeler applications. The programs are 3ds Max, Maya and Cinema 4D. The comparisons focus on the possibilities/the amount of freedom these programs interface offer to its plugins. The comparisons are made from the point of view of a tool for creating animations developed as a plugin for these modelers. This plugins demands on the system it is loaded into have been analyzed and from the results of this analysis a template have been created.

The objective of this study is to determine if and how Swedish businesses measure the efficiency of their purchasing departments.In this study I have interviewed six medium to large successful companies and asked them· Which ratios they use to measure the efficiency of their purchasing departments· Why they use these ratios and· How the results of these measurements are usedI can conclude that although there are no ratios or other measurements that directly measure the efficiency of purchasing indirect measures do exist.The measures applied are usually the result of demands from management and the results are reported back to management and used to follow development within a particular field of purchasing. Benchmarking, especially external benchmarking, is unusual..

The aim of this undergraduate thesis was to formulate advices regarding the use of field beans, cultivated together with spring wheat, as whole-crop silage in feeding to dairy cows. In the thesis, optimal harvest time of the field bean/spring wheat crop, as well as the feeding value and the fermentation quality, was studied. On the research station at Röbäcksdalen in Umeå field bean/spring wheat (70 % respective 30 % of normal seed rate for the pure crop) and pea/oat (70/30) was grown in field experiments both 2002 and 2003. The following year, 2004, the pea/oat crop was excluded and instead field bean and spring wheat was cultivated in three different mixed ratios (field bean/spring wheat; 100:0, 70:30, 30:70). Every year the crops were harvested at four different development stages and the green forages were used in ensiling experiments.

The aim of this study was to analyse ninth graders self reported screen based activities, sedentary time and musculoskeletal symptoms and pain intensity. The other aim was to examine changes regarding musculoskeletal pain and inactivity between ninth graders from a cross sectional study in year 2004. To meet this aim, following questions were designed: How is the relationship between screen based activities, inactivity, musculoskeletal symptoms, pain intensity and differences between girls and boys? How have musculoskeletal symptoms and screen time changed since year 2004?Method: The method used for this study was a quantitative method. The research was carried out using a questionnaire that was answered by pupils from 11 schools from all over Sweden.

Vår studie är gjord för att se om det finns någon skillnad i mellanstadieelevers beteenden i klassrum respektive idrottshall. Våra frågeställningar är: Finns det skillnader i beteendena hos mellanstadieelever i idrottshallen respektive i klassrummet? Finns det några skillnader mellan pojkars och flickors beteenden? Hur yttrar sig eventuella skillnader och vad beror de på? För att komma fram till detta har vi använt oss av observationer som metod och observerat årskurs fem-klasser på två olika skolor. I arbetet har vi kopplat vår empiri till Connells teori om hegemonisk maskulinitet och Goffmans beteendeteori Front-stage och backstage. Vi har också använt oss av behaviorismens grundläggande tankar om hur en miljö kan påverka ett beteende.

There are no reliable, objective and simple methods today for measuring pain in horses. The purpose of this study was to evaluate and describe measuring of mechanical nociceptive threshold (MNT) values with a pressure algometer in clinically pain free riding horses at the riding school of Strömsholm. In this study there were 24 horses. Tape recording and electromyelografi (EMG) was used in an attempt to increase objectivity in the examination. MNT increased with age, however sex and colour had no influence.

This essay describes the phases of funeral rituals between the Syrian/Assyrian, and compares the homeland with Sweden. It describes the stage of rituals according to Victor Turner schema of separation, margin or limin, and aggregation. The rituals religious significance agrees with Clifford Geertz?s theory about the importance of religious beliefs for the human being.

Generally, the economic health of Swedish roundwood truck transport companies has not been good. Profitability is important for maintaining the stability in the transport business, which is a condition for long-term transport planning in the forestry sector. The scope of this study was to identify probable factors influencing the profitability of roundwood truck transport companies and quantify the influence of these factors on economic results. The study was carried out at a major roundwood truck transport organisation in mid-Sweden and was implemented in four steps. In the first step economic results from the haulage contractors were collected and a random sample was taken from accounted net margin for the account year 2005/2006. In the second step hauliers were interviewed to identify probable success factors. At the third step data for identified factors were gathered through a questionnaire.

 The aim of this two-years master?s thesis is to examine the role of the body and the importance of nonverbal communication in the library workplace and to explore the possibility of becoming more nonverbally skilled. For this purpose a course was developed and presented to nine librarians in a public library in the vicinity of Stockholm in February, 2011. Qualitative interviews with the librarians were conducted after the course.Important theories for this work were Annemaree Lloyd?s thoughts on corporeality, Erving Goffman?s dramaturgical sociology and John Dewey?s learning by doing.

Syfte: Syftet är att försöka urskilja samband mellan hushålls socioekonomiska faktorer och efterfrågan på specifika bostadsattribut. Vår frågeställning är: Finns det samband mellan vilka specifika attribut som efterfrågas hos bostadsrätter och hushålls socioekonomiska faktorer? Vår förhoppning är att åtminstone få en indikation på vad olika typer av hushåll efterfrågar.Metod: Denna studie baseras på en databas bestående av bostadsrättsförsäljningar som skett i Gävle under år 2008 samt socioekonomisk information om de hushåll som förvärvat dessa bostadsrätter. För att estimera hushålls efterfrågan på ett specifikt bostadsrättsattribut har en tvåstegsmetod använts. I ett första steg avslöjas de underförstådda marginalpriserna av bostadsrätters egenskaper med hjälp av den hedoniska metoden.

Den här rapporten redogör för utveckling, design och sömnadskonstruktion för en sadelpadd. Rapportens ämne valdes för att jag fann det intressant och har själv stort intresse för hästar och produktutveckling. Fokus på rapporten låg på att ta fram en fungerade prototyp som testades av hästägare för att se om en distansväv skulle klara av att vara det stötdämpande och tryckutjämnande materialet i en sadelpadd. Rapporten och utvecklingen av rapporten bygger på en enkätundersökning och några intervjuer med relevanta personer insatta i ämnena sadelpadd och ryggskador hos hästar. Utifrån den insamlade informationen från de intervjuade och de som svarade på enkäten samt tidgare skrivna källor gjordes en studie i hästars uppkomst av ryggbesvär.

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.
