In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

Sweden recently changed the national regulation of chimney sweeping. This study has two purposes. The first purpose is to evaluate the effect of this reform to see if the new regulation has led to an effect in terms of increased chimney fires in single-family houses and for the wood-burning and oil-burning stoves, respectively. The second purpose is an updating of a previous study (Mattsson 1994) of analysis of society´s benefits and costs of different alternative sweeping frequencies for wood-burning and oil-burning stoves. This study also has a secondary purpose to examine the extent to which the local sweeping rules vary with climate conditions.  Mattsson, based on his results, proposed that the sweeping requirements for oil-burning stoves should be reduced from twice a year to once every second year and for wood-burning stoves the sweeping should be reduced from four times to once each year.

By doing this thesis I want to open up farmers and tractor drivers mind to see that there is several risks with their work. There is a number of risks that everybody probably already know about, and hopefully I will, with this work, help them to see a lot more risks, to make them be more careful in the future. I?ve interviewed seventeen farmers in middle and south of Sweden. I?ve also asked them for their opinion and what kind of changes they looking forward to.

The main purpose of this Master's thesis is to investigate the new librarians' experiences and skills in the context of their present work situation and the ongoing debate about the librarian's professional identity and status. Further, the authors wanted to find out whether the new librarians' experiences and knowledge developed throughout their education correspond to the requirements of the employers. Finally, they try to assess theimpact of the "academization" of the library schools on the status of the profession. The data consist of an opinion poll. The investigation is based on questionnaires distributed as a web survey.

The aim of the study is to examine what upper secondary school students think that they themselves and their school can do to create a peaceful society. The study combine qualitative and quantitative methods based on questionnaires distributed among 328 students in three high schools in Sweden. The survey is a combination of multiple choice and open questions. For the analysis of quantitative responses the computer program SPSS was used producing frequency tables and response rate schemes. To analyze the questionnaire's qualitative part a narrative analysis method was used.

The purpose of this master thesis is to understand how busy moms experience their grocery shopping trips and the in-store environment. In gaining this knowledge, we aim at being able to suggest ways to improve the grocery shopping experience of busy moms; and present insights that can help food retailers in targeting this consumer group in-store. Methodology: We use an iterative approach, and work with photo elicitation interviews. We let our respondents capture their experiences in photographs, which then aid in recalling their memories in follow up interviews. Theoretical perspective: We base our theoretical perspective on environmental psychology where we use the original M-R model, and include personal and situational variables suggested by Bäckström and Johansson (2006); where the latter variable includes the views by Turley and Milliman (2000).

The conditions for art in Romania have gone through big changes since the collapse of the regime in December of 1989. Under the Communist regime the artists had to work within a dualistic system completely unlike the one that developed in the West during the same period.Similar to the other countries of the former Eastern block, the communist Romanian state had understood the great potential that art has as a form of propaganda. Thus the regime secured full control over the art that would be allowed into the public space. In response to the confines set on the artistic expressions, a non-official art began to develop alongside the official art of the state.These two layers of Romanian art history were dissolved when Ceausescu?s regime finally came to an end in 1989.

This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.

The purpose of this study was to investigate the presence of arterial insufficiency in patients undergoing CABG surgery and whether arterial insufficiency is a risk factor for postoperative wound infections in the harvesting leg. Patients who had CABG surgery were enrolled consecutively. A total of 144 patients participated in the study. During their hospital stay demographic data was recorded, as well as pre-, intra-, and postoperative tests and risk factors. The patients answered a questionnaire regarding postoperative wound infections 30 days after surgery patients answered a questionnaire regarding infections.

AbstractThis study explores how well teachers think they succeed in their mission to include children with special needs into their ordinary groups of children. Interviews were carried out with five teachers in practice of the public school (year 2,3,5 and 6). The teachers were asked what support they have got from the schools manager, initially and ongoing, (information, necessary education, supportive expertise personnel, assistant teacher to the child and schoolmaterial.) The teachers were also asked how inclusion is arranged by three indicators of participation: physically, socially (interaction) and didactically -in educational situations of reading and writing. One finding of the study was that inclusion is difficult to arrange if  parents of included children demand secrecy of the diagnosis their child has. Three cases reveal severe problems of acceptance for the included child by the peers.

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

Colobus angolensis palliatus is a small old world monkey inhabiting southern coastal Kenya to southern Tanzania. The species activity budget is known to vary between seasons and areas, probably due to differences in group sizes, diets, predatory presence and resource competition. The variations between male and female activity budgets are reckoned to be a result of pregnancy and lactation. The aim of this study was to investigate potential differences in behaviours between morning and afternoon periods and between males and females. The study was carried out in two forest fragments in Diani Beach on the south coast of Kenya.

The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.

The purpose of the case study is to research whether the brand Hollister can establish themselves to their target audience working with communication. To achieve the goal with the study, the following theories has been applied: brand building, visual communication, two-way symmetrical communication and communication channels. The study was conducted by a quantitative online questionnaire survey. The online survey was aimed at teenagers aged 15-18 years old living in Täby or Umeå where one question was "What difference can be discerned between Täby, where there is a shop, and Umeå where there is no shop". The material was collected during a period of eight days between december 11th to december 19th 2013.

The idea behind this project came from a feed study executed two years during the lambing season. Both years wool loss was experienced. Low temperature in combination with shearing was believed to cause the wool loss the first year, while protein deficiency was believed to be the cause the second year. In the literature many causes of wool loss are described; mechanical wear, telogen effluvium, bacterial dermatitis, external parasites, wool break, scrapie, genetic causes and nutritional deficiencies are some examples. The aim of this thesis was to study causes for wool loss and how common wool loss is in Swedish sheep herds.
