The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.

Chemotherapy is one of the most important methods of treatment available today for the treatment of neoplastic diseases and gives many patients an increased quality of life and a prolonged survival time (McKnight, 2003). The object of this study was to find out more about owners? views on and experiences of chemotherapy of dogs when it comes to for example quality of life, side effects and if they would make the same decision and treats their dog again in the future. A questionnaire was in the spring of 2009 sent out to the owners of 100 dogs that had been treated with chemotherapy for neoplastic diseases at Universitetsdjursjukhuset, Sveriges Lantbruksuniversitet (SLU) in Uppsala between 2002 and 2008. The response rate was 67 %.

This essay revolves around the reformation and sectorization of Swedish psychiatry starting in the 1970?s. Psychiatry was to change from being based in closed asylums to being an institution in the middle of society, finding social solutions to mental illness and working through a dynamic network of various care givers, such as welfare officers, nurses and psychiatrists. This new kind of psychiatry was first tested in Nacka, where psychiatric reformers Johan Cullberg and Bengt Berggren were the heads of a six-year long pioneer project of sectorized psychiatric care. My specific purpose is to analyze the new ideas of mental illness and of psychiatry?s role in society which were introduced in this project and how they were expressed in the official reports presenting it.The reformation was preceded by a public debate concerning psychiatry, which had intensified a few years around 1970.

Bakgrund: Finanskrisen 2008 påverkade kreditmarknaden och konsekvensen blev att företag fick det allt svårare att få lån beviljade samtidigt som lånevillkoren försämrades. Detta borde påverka företagens finansiering då de inte har samma möjlighet att välja sin kapitalstruktur och på så sätt utnyttja de fördelar som lånefinansiering medför. Vidare är det fortfarande oklart vad som påverkar företags val av kapitalstruktur. Det finns få kvalitativa studier gjorda inom ämnet varför det är av intresse att studera kapitalstrukturen och dess påverkande faktorer ur ett djupare perspektiv.Syfte: Syftet med studien är att studera vilka faktorer som påverkar företags val av kapitalstruktur och hur arbetet kring kapitalstrukturen ser ut samt studera om det förändrats till följd av finanskrisen 2008.Metod: Studiens metod är av kvalitativ karaktär och åtta företag har deltagit. För att uppnå studiens syfte har en representant från respektive företag intervjuats vilket tillsammans med tidigare forskning och teorier har legat till grund för diskussionen i analysen och de slutsatser som författarna har konstaterat.Slutsats: En mängd olika faktorer påverkar valet av kapitalstruktur men den främsta faktorn är verksamheten som bedrivs, vilka strategier och förutsättningar bolaget har.

SEB Merchant Banking provides to its institutional customers a true market neutral product called Dynamic Manager Alpha (DMA). The DMA is constructed by a long position in an exceptionally well performing mutual fund and a beta adjusted short position in an appropriate index. The key to making the product market neutral is adjusting with the correct beta, since the beta changes, it is very important to have a good model for predicting beta in the future.This master thesis begins with describing what beta is in a CAPM sense. It then continues with recognizing the so called ?Two Beta Trap?, which separates two kinds of beta.

The purpose of this essay is to illustrate the preparation of total and civil defense education in schools in the 1970s to gain insight into how the school looked and pondered the complicated world that existed outside the school's doors. By using the concepts of welfare state, welfare and civil defense culture, I have studied relevant materials to get answers to questions treating the total and civil education in schools after Lgr69, the way the state sees the subject and if it is possible to detect a civil defense culture in schools and if so, how it will be expressed.     The results show that the state emphasized education as incredibly important because knowledge of how to act in a crisis or war could be extremely crucial for the individuals and their survival. The education was so important that it got a role as a main factor in Lgr69. But even if the education was important the teachers had huge problems with the schedule and many teachers couldn´t educate all facts because they didn´t have enough time.

Muskuloskeletala problem och dysfunktioner är vanliga bland befolkningen och kan ofta kopplas till myofasciella triggerpunkter. Utmärkande för en triggerpunkt är en o?m palperbar knuta i muskulatur som a?r ka?nslig fo?r kompression. Om tryck appliceras pa? triggerpunkten kan den ge utstra?lande sma?rta och ofta uppstår ett så kallat local twitch response.

Som slutkonsument är det inte alltid lätt att förstå varför en butik erbjuder ett visst produktsortiment och kunderna har sällan insyn i vad som styr och påverkar dagligvaruhandelns utbud av varor. Uppsatsen syftar till att ta reda på hur butiker resonerar när de väljer sina leverantörer och vilka faktorer som styr deras val. Studien är baserad på en kvalitativ undersökning där personer från fem ICA-butiker i Uppsalaområdet har intervjuats. ICA AB är landets dominerande grossist med inriktning på livsmedel och detaljhandel varför enbart ICA-butiker har tagits med i undersökningen. De valda butikskategorierna är ICA Supermarket och ICA Nära där alla använder sig av samma huvudgrossist och kompletterar sitt sortiment med varor från andra leverantörer. På så sätt kan de anpassa sitt varuutbud efter sin butiksprofil.

Long transport of products is an environmental issue discussed to an increasing extent. The consumers are increasingly aware of how far our comestibles really have been transported. The increasing levels of environmental emissions are something that concerns people. The question is nevertheless delicate and many choose to ignore it. This is no longer an option.

Since the 1990s, when the number of transnational companies increased, it has created challenges regarding the responsibility of human rights. As a response to these challenges the United Nations Human Rights Council (UNHRC) unanimously endorsed the new policy UN Guiding Principles on Business and Human Rights (UNGP) in 2011. UNGP does not have the status av international law, yet simply as guidelines and its implementation is based on good will and voluntary efforts. Now, 10 years later, this study aims to get understanding regarding if UNGP is considered as norm by the Swedish Government, Volvo and Gothenburg Municipality. The material of the study consists of sustainability reports, annual reports and governmental documents with focus on human rights in relation to business published between the year of 2011, when UNGP was endorsed, until 2020.

Research has shown that students with another mother tongue than Swedish terminate elementary school with lower grades in all subjects, compared to students having Swedish as a mother tongue. This fact justifies further research on the forms of teaching Swedish as a second language. Attention has been given to the fact that the students with another mother tongue than Swedish have to cope with "dual learning". Parallel to the learning of a second language they need to obtain knowledge in all other subjects. The purpose of this thesis is to investigate how the School organise the work with students having another mother tongue than Swedish, and to find out how teachers in other subjects solve the problem of having students that struggle with "dual learning".

In the EU there are EC Directives that Member States of EU should follow. Sweden has undertaken to transpose EC Directives regarding the working environment to Swedish Provisions.  In 4 April 2006, the European Commission had some criticism against the Swedish implementation of the Construction Sites Directive. The Swedish Work Environment Authority has in response to this criticism reworked the Work Environment Act and related provision about building and civil engineering work. The changes came into force 1 January 2009.These changes have resulted in some working methods and even new responsibility subjects must be reviewed. The purpose of this exam project was to investigate if contractors and clients in the construction sector, had have time to update themselves on this front and adapt to these changes.

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.
