Denna rapport bygger på en litteraturstudie och avser att ge en bred beskrivning av en teknik kallad LTES (Latent Thermal Energy Storage). Rapporten förklarar teorin bakom tekniken, behandlar de komponenter som krävs för att praktiskt kunna använda den, tittar på kostnader som är förknippade med den och visar på tillämpningar som finns idag och är förväntade inför framtiden. Vid LTES genomgår ett PCM (Phase Change Material) en fasändring vid en viss temperatur. Vid fasändringen lagras (eller avges) termisk energi i (från) PCM:et. Denna fasändringsprocess kan sedan användas praktiskt i olika produkter och system för att ge värme och/eller kyla efter behov.

GE Healthcare wants to investigate whether additive manufacturing would be an alternative method in their workshops in the Umea? plant. Additive manufacturing is called 3D printing in everyday language and manufactures details by building them up layer by layer in an automated machine. The purpose of this work is therefore to investigate how mature additive manufacturing methods are and how they could be used at GE.The work has been divided into three parts. The first section investigates how additive manufacturing would work in the production workshop at GE.

Bakgrund: Alkoholberoende skapar stor makt över en människas liv och kan beskrivas som en ond accelererande spiral. Smärtsamma känslor dövas med alkohol men ger på sikt ett ökat lidande och personen kan inte längre kontrollera sin situation. Den alkoholberoende flyr in i en förnekelse inför sig själv och andra vilket skapar än mer lidande. Syfte: Syftet med studien var att beskriva den alkoholberoendes upplevelser av sin livsvärld. Metod: För att besvara syftet användes en kvalitativ ansats och som datamaterial användes fyra självbiografier.

How does the computer influence teenagers' lives. I interviewed five young people, and gave a questionnaire to another 47, about this.What I found was that they were aware of and handled well the risks with the Internet and the computer, but had problems with the computer taking too much of their time. They wanted more time for their families and outdoor activities. It was mainly the Internet that seemed to have an influence on the teenagers, not the computer as a machine. They told me that there was a rough climate on the Internet, partly because of the possibility of being anonymous.

Risk analysis in connection with transportation of dangerous goods is associated with great uncertainty. In addition there are a number of specific problems that the risk analyst faces when risks associated with transportation of dangerous goods are to be analysed. In this report those problems and uncertainties are described.One of the most important conclusions in this report is that uncertainty analysis within risk analysis in connection to transportation of dangerous goods has to be made more effective..

This paper aims to derive the Black-Scholes equation for readers without advanced knowledge in finance and mathematics. To succeed, this paper contains a theoretical chapter in which concepts such as options, interest rate, differential equations and stochastic variable are explained. This paper also presents the theory of stochastic processes such as the Wiener process and Ito process. In the chapter on the Black-Scholes model the Ito process is used to describe price of shares and with the help of Ito's lemma Black-Scholes equation can be derived. In the paper, assumptions are listed that apply to the Black-Scholes model and then uses the Black-Scholes equation to calculate the price of a European call option.

The Yangtze finless porpoise (Neophocaena phocaenoides asiaorientalis), is a small freshwater cetacean which has recently fallen dramatically in number. It is an endemic species for the Yangtze River and unless drastic action is taken, it risks the same fate as the now functionally extinct Yangtze river dolphin (Lipotes vexillifer). Threats to the porpoise are diverse but they have in common that they are caused by man. Development of the river has been made to supply a growing human population with food, hydropower, and to reduce the risk of flooding. These changes have resulted in a degraded habitat for the porpoise.

The purpose of the essay has been to clarify why and how small companies, whose major resource is knowledge, establish strategic alliances and which opportunities it brings. We have increased our understanding for the concept of strategic alliances through empirical search and through well-known scientist work. The method, which has been used in the essay, is principally qualitative interviews and gathering secondary data from articles from well-known authors. Our study has given that we have found that entering strategic alliances can make growth and by that way create competitive advantages for the company in question. We also found that there are risks with strategic alliances and the company can protect themselves by legal actions.

Sjuksköterskor på sjukhusavdelningar upplever stress genom höga krav och lågt stöd från arbetsgivaren, låg kontroll över arbetet och stor arbetsbelastning. Syftet med den här studien var att beskriva vilka stressorer som finns hos avdelningssjuksköterskor på sjukhus och vilka copingstrategier de använder för att hantera stressen. Frågeställningar till studien är: Vilka stressorer finns hos sjuksköterskor som arbetar på sjukhus? Vilka copingstrategier använder sjuksköterskor på sjukhus för att hantera stressen? Studiens metod är systematisk litteraturstudie. Analysmetoden är latent innehållsanalys.

The thesis is based on a case study of a Swedish discussion forum where survivalism and prepping is the main focus. The awareness of an abrupt and immanent breakdown together with a full and thorough preparation for any conceivable threat posed by that breakdown is what legitimizes survivalism and prepping. This preparation, or risk-proofing is 1) grounded in an isolation of the body and its predispositions from perceived risks, and 2) actualized through artefacts, theoretical and practical knowledge and awareness. Stories of the embodied survivalist are also stories of masculine and heterosexual subjects and ?the others?.

Virala orsaker till reproduktionsstörningar så som abort, resorption av foster och dödfödda valpar är hos hundar ofullständigt kartlagda. Herpesvirus är det agens som har studerats mest och är även ett välkänt abortagens på andra djurslag, däribland häst. Hundens herpesvirus (CHV-1) orsakar hos vuxna individer i regel endast milda respiratoriska symptom. Hos dräktiga djur kan viruset ge upphov till förlust av valpar och även orsaka en kraftig och dödlig infektion hos neonatala valpar. Precis som många andra herpesvirus kan CHV-1 ge upphov till en latent infektion som kan reaktiveras vid stress.

Purpose: The purpose of this study is to seek understanding, describe and analyse how auditors practically reassure and maintain their independence towards clients.Methodology: The study is conducted with a qualitative method with a deductive approach. The study is based on interviews with both experienced and recently graduated auditors.Conclusion: Our empirical results show that there are economical incentives that contradict the requirements to fulfil the auditor?s independence. The conclusion is that the media view is narrow and biased. Furthermore the auditors agree that an acceptable level of comfort is achieved by offering a high value, being a part of a large network of professionals and the ability to set materiality and evaluate risks. .

Syftet med studien var att undersöka vad unga vuxna samer upplever som hälsofrämjande i sina liv. Totalt deltog tre 18-åriga samer. Metoden bestod av enskilda intervjuer samt bildskapade och bildtolkning i grupp. Vid bildtolkningen fick deltagarna ge bilderna nyckelbegrepp, vilka användes som grund i temaskapandet. Textmaterialet analyserades med en latent innehållsanalys.

The purpose of this study is to gain a deeper understanding of women's violence against men in intimate relationships, get an idea of ??what forms of expression that this type of violence has and to highlight the men's experiences of violence.There is little scientific research in the field in Sweden. Crime Prevention Council has determined that eight percent of all complaints involving domestic violence in 2010, reported by men over 18 years. You can only speculate on how large number of unreported cases is among abused men. The international studies highlight that the abused men feel ashamed of having been subjected to violence by a female partner.I have been based this essay on two theoretical premises, Per Isdal theory of "violence perspective" and Elaine Bergqvist's definition of the suppression technique.The study was conducted through a qualitative content analysis.

Bakgrund: Diabetes har blivit ett av de framträdande folkhälsoproblemen som sträcker sig längre och längre ned i åldrarna. Tonårstiden är en fas i livet som kan vara komplicerad och att dessutom som tonåring insjukna i en kronisk sjukdom kan ytterligare försvåra situationen. Hur tonåringen upplever förälderns roll i detta skede kan vara av betydelse för hur egenvården utvecklar sig. Syfte: Syftet med föreliggande studie var att undersöka hur tonåringar med diabetes typ 1 upplever föräldrars roll och vilken betydelse det har för egenvården. Metod: Studien är en litteraturstudie som utfördes med hjälp av åtta kvalitativt analyserade artiklar.
