Konvertering från luft till vätskekylning av elektronik
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.
The Green Evolution of the Car Industry
This Master Thesis covers the concept of Green Cars. The background to the research area is the high and rapidly growing number of cars, which together with other factors ad to the pollution of the environment. Under the Kyoto agreement the signing members agreed to lower the emissions of green house gases, further on the EU has a 3-pillar strategy on carbon dioxide and cars. Included in the EU strategy is a voluntary commitment from the car industry to reduce carbon dioxide emissions from new cars. The easiest way of lowering the emissions is by using alternative fuels and engines.
Faktorer som påverkar en miljöinvestering
Syftet med detta examensarbete är att göra en jämförande studie mellan faktorerna som enligt en teoretisk ram påverkar en miljöinvestering och faktorerna som ingår i ett företags bedömnings-modell. Respondentbolaget begärde i ett tidigt skede att få vara anonymt och benämns därför som Företaget. Det är en multinationell koncern med verksamhet i många skilda branscher, men med fokus på norden och produkter som kan kopplas till lantbruk. Den teoretiska referensramen har sin utgångspunkt i begreppen värde och investering samt hur deras koppling till miljö och miljöinvesteringar för att identifiera de faktorer som påverkar en miljöinvestering. Faktorerna som ingår i den teoretiska referensramen och som jämförs mot respondentbolagets faktorer är:? Investeringens värdetillförsel? Investeringens miljöpåverkan? Hur investeringen påverkar produktionsförutsättningarna? Krav från samhället? KundkravKopplingen däremellan bedöms enligt en femgradig skala.
Utbilda och forska är vi bra på - men att samverka? : En kritisk studie av Högskolan i Gävle och den tredje uppgiften
The cooperation between university and industry life in the region of Gävle is always a topic of importance. University and High schools have various roles to fulfill: except administrating the training and supporting research they should also - as a third role - contribute to cooperation between organizations, business companies and other associations. In addition to that, they should support individuals by local as well as regional development. The purpose of our paper is to make a critical review of the cooperation between the University of Gävle (HiG) and industry life until today and the consequences in order to encourage students to stay in the Gävle region during and after their period of studies.Initial we started with a preliminary inquiry with a questionnaire as a base for students in three programs at the Department of Economy; the program for Bachelor of Science, the program for estate agent and another economy program with direction estate economy. From this preliminary inquiry we got the picture of the way the students looked at the problem.
Godtagbara ändamål vid fastighetsbildningenligt 3:1 FBL : - en studie om ?udda? ändamål
The main objective with this study was to investigate so called odd purposes acceptable when registrating property along with how social development affects these purposes, furthermore to investigate how the cadastral surveyors estimates a foreseeable time. Tradition and praxis is used for several obvious purposes such as housing, farming, forests, offices and industry. Praxis is yet to be defined regarding more unique purposes. There is no mention in the law about which purposes are found acceptable to assure the demands on suitability are met. Cadastral authorities are responsible for making sure the division into property units is uniform and rule of law-accordingly.

Lokal etisk produktion ? är den globalt hållbar?
In modern society globalisation is a fact within all industries, the textile industry included. Due to improvement in areas such as logistics and communication international trade have developed fast. As changes occur rapidly on the global market and companies must adjust and revise their processes in order to stay competitive.Because of the global price reduction consumers around the world expect low-price products, which mean that the companies have to find new ways to produce in a cost-efficient way. To maximize profit most of the textile production is situated in low-cost countries due to its labour-intensive character. It is crucial for fashion companies to allocate their activities in their value-chain effectively in order to reduce lead-times.
Användande av avskjutningsstatistik i förvaltning : påverkar tidigare jakt CPUE?
In fisheries, there is a long tradition to use catch data when evaluating changes in the stock and effects from harvesting. It is a common practice to use Catch Per Unit Effort (CPUE) as an index of population size, and several studies have investigated the properties of CPUE in relation to population abundance, spatial distribution and efficiency of gear. In research, catch rate on trap-transects is used as an index of abundance for wildlife species but CPUE is rarely applied as a tool in harvest management.In 1993, more than 60 000 km2 of the state managed mountain range in Sweden was opened to the public for small game hunting, under the responsibility of the county administrative boards in Jämtland, Västerbotten and Norrbotten. The total area is now divided into 332 hunting units (median=73 km2) and an internet based system is used to administer licences and reporting bag statistic. Each hunter has to register the results within two weeks after the hunt.
Pojkkrisen ur ett historiskt perspektiv : En studie av pojkars respektive flickors förändrade beteende, deltagande och resultat i skolan utifrån lärares historiemedvetande.
Popular culture is a phenomenon of growing importance in the society today. Children and teenagers are increasingly using popular culture in their everyday life to reflect and answer questions about their identities and the meaning of life. Swedish primary and upper secondary schools are expected to prepare their students for adulthood and to provide them with tools to explain understand and problematize contemporary society. From this perspective it is relevant to question whether the schools achieve this and whether the instruction given there represents the contemporary society. For the purpose of knowing more about how popular culture is perceived and dealt with in the Swedish education system, this study examines how eight textbooks in Religious Education (RE) and the national curriculum for upper secondary school discuss and treat popular culture. The study focuses on when and in what ways the textbooks mention popular culture and if the curriculum provides any supportive base for including popular culture in religious education.

Kan ett ökat intag av omega-3- fettsyror påverka testosteronnivåer hos kvinnor med PCOS?
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Can an increased intake of omega-3 fatty acids have an effect on testosteronelevels in women with PCOS?Author: Ylva Dernbrant och Helene HagenborgSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundPolycystic ovary syndrome affects women of fertile age and consists of elevated testosterone levels and increased insulin resistance along with effects on ovulation and fertility. The elevated level of testosterone often leads to problem with acne and hirsutism, and it is also common with overweight and metabolic syndrome. The nutrition treatment has mainly consisted of energy restriction, together with exercise and drugs to reduce insulin resistance and consequently reduce androgen levels. However, an in-depth knowledge about how the components of our diet can affect further, is lacking.Omega-3-fatty acids can affect insulin resistance and testosterone levels within other groups but today knowledge is lacking if these findings can be transferred to women with PCOS.
