A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

Opcon Powerbox is a product developed by Opcon together with the underlying company SRM (Svenska Rotor Maskiner) where surplus heat from the industry is used through an Organic Rankine Cycle (ORC)?process to produce electricity. An ORC-process is a thermodynamic circle process in which a refrigerant is used as the working fluid. The refrigerant makes it possible for the circle process to operate at lower temperatures than the conventional Rankine process.In this master?s thesis a data analysis software for the Opcon Powerbox has been developed in which measurement data is retrieved and handled from the Opcon Powerbox.

A method for equine intra oral radiology has been tested. In the study, both a digital system with an intraoral sensor connected to a laptop and a system utilizing image plates and digital developing was tested, initially on cadaver sculls and finally on sedated horses. The digital sensor was not considered viable for this purpose, while the system with image plates and digital developing worked very well. Two different techniques, i.e. parallel and bisectris, are suggested for the best visualization of different parts of the teeth. Intra carious injections of Mixobar oesophaghus contrast fluid was found useful when evaluating the extent of carious lesions. Compared to extra oral radiology, the new method had several advantages and can be used both in clinic and field practices..

Chiari type I malformation is a condition in humans characterized by a small posterior cranial fossa, downward herniation of the cerebellar tonsils, foramen magnum overcrowding and disturbances of cerebrospinal fluid dynamics. Syringohydromyelia is often seen in patients with Chiari type I malformation. Syringohydromyelia is characterized by fluid-filled cavities in the spinal cord. This causes damage to the nervous tissue in the spinal cord. In recent years, a condition similar to Chiari type I malformation has been recognized in dogs. It has mostly been seen in Cavalier King Charles spaniels (CKCS). The condition seen in dogs is usually called occipital bone hypoplasia. The aim of the study was to examine whether there is a difference in the shape of the caudal fossa between CKCS, small bred dogs with a similar head shape and dogs with a normal head shape and if occipital bone hypoplasia is related to a head shape with a steep back of the head. Other aims of the study were to examine the crowding of nervous tissue in the foramen magnum in each breed group, the extent of syringohydromyelia and to what extent the malformation had caused neurological signs. Sculls from dogs on autopsy were divided in halves and the position of the cerebellum compared to the level of the foramen magnum was studied.

It is not about the perfect tune or pretty picture.It is always, always about the story. (Is or ought to be)When we release a new album, publish a book or show a brand newcollection of clothes or furniture etc. it is (or ought to be) because we havesomething to say (tell/share). The choice of language, in which we tell our stories,is vital for how they will be perceived.This is where illustration comes in. Illustration is a tool for storytelling, for contributingto the world in the most legible way.Illustration is legibility, it is the italic, the underline, the ?quotation mark?, the exclamation mark!It is not about the pretty picture.I want to talk about this.

This study aspires to find an answer to what makes a negotiation for peace successful. In our pursue to do so we have chosen two cases to compare with each other through a set of different theories. The theories we believed could be relevant were ripeness/readiness, asymmetry, the strategies of mediation, intra-state conflicts and personal actors.The case-study consists of two negotiations that both took place in Camp David. The first one was between Egypt and Israel, 1978, and serves as the example of a successful negotiation. The second case was, again, with Israel but the counterpart was Palestine and took place in year 2000.

There are lots of theories about participatory democracy, but rather few examples of how to create it in practice. In the 1930´s, scientists at the Chicago School, implemented some projects within the Chicago Area Project, with the aim to decrease the youth delinquency in the socio disadvantaged areas surrounding Chicago. In this thesis, I assess wether these projects, and in particular the one at the Russell Square Area, have some common features with the thoughts of two of the most famous participatory democrats, Carole Pateman and Benjamin Barber. My question is if the Chicago Area Project could be seen as an experiment in participatory democracy. I find that participatory democrats could benefit from the experiences of the Chicago Area Project.

Many studies have pointed out that generosity depends on different things like gender, age and nationality. We wanted to see if predetermined factors like genetics also had an effect on the intention of generosity. There is a ratio between the index finger (2D) and ring finger (4D) that is determined by the levels of testosterone in the amniotic fluid and that have had some significant effect on personality attributes like musical and leadership skills. We wanted to see if that ratio had any effect on the intention of generosity. We experimentally examined a group of priest student and two groups of young handball players and let the groups answer a survey that included a sort of dictator game and we photo copied their hands to get their 2D:4D-ratio.

This study is primarily an account of my examination work in archival science which took place in the archive of Margareta Böttiger, the state epidemiologist at the Swedish Institute for Communicable Disease Control Stockholm. The records are from Böttigers period of work, mainly divided into three parts, polio, HIVS/AIDS and vaccination. Of these I have focused on polio with was the area she got renowned for. Moreover, owing to the uniqueness of the material this study has focused on the properties of the archive as a working-life archive which I propose as a special type of personal archive with unique attributes. To summarize, a working-life archive has in comparison with other personal archives a more fluid process of archiving where the profession is important, not the personal production of records.

Studien undersöker hur man på ett praktiskt sätt kan knyta samman musikteori-, gehörs- och ensembleundervisningen. Syftet är att undersöka möjligheten att i jazzsammanhang träna sitt gehör i grupp vid sina instrument. Jag har utvecklat tre gehörsövningar som undersöks i den här studien. Övningarna är konstruerade så att exempelvis pianisten skall övas i att höra basgångar, medan basisten övas i att höra ackordläggningar. En av ensembledeltagarna (piano, gitarr, sång, blås eller bas) styr övningen och väljer hur ackordföljden ska fortsätta genom att följa vissa regler (exempelvis upplöses dominanter alltid ren kvart upp/ren kvint ner).

This essay tries to show how The Swedish Museum of Architecture, Stockholm, with the exibition Architecture in Sweden - Function, Design and Aesthetic through the Ages, presents and represents architecture. It is stated that this is done in a multi-perspectival, multimedial fashion, with the aid of, for example, photography, models and mixed material surrounding the wide concept of ?architecture?. One chapter discusses the relationships between the exhibition on site, the exhibition catalog and the museum´s website. Another chapter argues that there can be no essential or perfect representation of architecture, although this utopian wish most certainly exists even today.

The purpose of the study was to review the current veterinary literature regarding gastric dilatation and volvulus (GDV) considering pathophysiology and treatment, and to evaluate the operative technique (incisional gastropexy) used during the years 2005 and 2006 at the University Animal Hospital (Universitetsdjursjukhuset), SLU, Uppsala, Sweden. GDV has a complicated pathophysiology which foremost effects the circulatory system. Progress is often acute and it is not unusual that patients are affected with shock. The initial treatment targets to alleviate the shock by fluid therapy and decompression of the stomach. There is a high risk of recurrence in the long term perspective unless the stomach is surgically fixated by gastropexy. The study describes two different techniques for gastropexy; incisional gastropexy, and funduspexy. Long term complications were rare among the patients that were treated surgically, while about half out of the eighteen dogs that undergo surgery do experience complications of various severity in the short term..

Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.

On average half of the sows in Swedish piglet producing herds are culledannually. A significant portion of the sows are euthanized because of lameness orparalysis. Young sows and gilts are overrepresented in the category of animals,culled due to injuries in the musculoskeletal system. These injuries cause pain tothe animals. Early culling of sows/gilts also have economical consequences forthe producers.

Värmekollektor in Sunne is a company whose main occupation is to collect the gas produced inlandfills. The gas contains about 50 % of Methane which is a greenhouse gas 20 times worse than CO2and should therefore not be allowed to leak into the atmosphere. The Methane is in as large amount aspossible used in different plants for example heating of households. But there are occasions when aflare is needed to burn the excess gas at standstills or testing of new landfills. The Flare only burns themethane to reduce the hazarder?s effect of the environment, it does not take advantage of the energy inthe gasThe goal of this master thesis was for me to create a foundation for an in-house production offlares for Värmekollektor.
