Biblioteket bokskogen : Perspektiv på bibliotek för barn på sjukhus
The purpose of this study is to focus on library service for children in a hospital, which in turn is seen in relation to a traditional children s library. Four aspects of library work were investigated. These aspects were working methods, partners of co-operation for the libraries, media policy (acquisition, use of the collection and circulation procedures), as well as programme activities for children.The research method was qualitative and comparative in nature, consisting of case studies of two libraries : (1) the library in a children s hospital, known as Bokskogen at Astrid Lindgren s children s hospital in Stockholm and (2) a traditional children s library, the children s department at Eslövs city library. In each library interviews were conducted. The investigation shows that the librarians in the hospital library must be more outreaching and active in order to stimulate children to use library materials.
Termisk Vattenpump
This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.

Spelberoende
We have written this paper about gambling problems with the purpose to give us and all of our readers a sense of understanding. With the term understanding we mean that we all know what type of activity gambling is but not a lot of us know how it feels for individuals that due to their addiction play almost every day and sometimes several times a day. By somehow trying to explain what kind of experiences people who engage in gambling feel, we hope that we somehow can increase our knowledge towards these persons and towards gambling. We are well informed that the content of our particular subject that we?ve chosen is massive and that more research needs to be done about or subject since there are no simple answers that can explain gambling behavior so easily.
Konstruktion av säkerhetslagerför svänghjul
This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.
Utvandrarna och friheten : En narratologisk undersökning
The purpose of this essay is to do a narratological analysis of Utvandrarna by Vilhelm Moberg to see how the form affects the theme of freedom and liberation. I used narratology as the method of analysis and my questions for the text regards the significance of the narrator, the use of focalization, the powers, helpers and opponents, the locations and spaces, and how these aspects affect the theme. In my analysis of the novel I found that the narration took place in three levels. This gave the story different perspectives of the theme; an outer perspective, a semi-distant perspective and a more personal perspective. The focalization of the main characters creates sympathies, and the focalization of non-main characters gives the reader an outer perspective on the characters.
Ny teknik för småskalig kraftvärme : - med fokus på Organisk RankineCykel (ORC)
As a part of the fight against the global warming the energy production needs to be more efficient and redirected towards sustainable options. One alternative is cogeneration, which means that electricity and heat is produced in one plant. The purpose with this survey is to examine if there are any commercial available combined heat and power techniques, based on combustion of solid moist biomass, which are suitable to small-scale applications. The technique must be able to produce between 2 and 10 MW thermal and the heat demand is a Swedish district-heating system. When already published reports had been studied, the Organic Rankine Cycle (ORC) was chosen as the most suitable technique.
Driftoptimering av torkmaskin : Driftoptimering av torkmaskin 3 vid Billerudkorsnäs Karlsborg AB
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Energimodellering av ett flerbostadshus - en parameterstudie : Granskning av energianvändning och termisk komfort
Idag står bostads- och servicesektorn för närmare 40 % av Sveriges totala slutliga energianvändning. Flerbostadshus utgör ca 30 % av den energianvändningen. Därför är det viktigt att lokalisera energiparametrar och redovisa dess betydelse för energianvändningen. Samtidigt bör relationen mellan energianvändning och inomhusklimat analyseras, så att inte förändringar i energin medför till försämringar för inomhusklimatet. Baserat på identifiering hos energisparpotentialen hos parametrar, parameterbeteende och parameterkänslighet för energianvändning har i studien ett antal parametrar undersökts för ett flerbostadshus.
Höns återhämtning efter stress samt domesticeringens effekter : En biologisk studie med ett lärarperspektiv
Den biologiska studien har visat att värphöns genom domesticeringen förändrat och anpassat sina beteenden till att leva med människor. De har utvecklat en minskad rädsla för människor och en ökad stresstålighet. I denna studie har höns återhämtning efter en stressupplevelse studerats. För att se hur domesticeringen har påverkat återhämtningen jämfördes beteenden mellan raserna White Leghorn och red junglefowl. Frågeställningarna som användes för att undersöka detta var: Hur lång tid tar det innan höns återhämtar sina naturliga beteenden, ej stressrelaterade, efter en stressupplevelse? Finns det några skillnader i återhämtningen beroende av kön eller mellan raserna White Leghorn och red junglefowl? Resultatet visade inte på en specifik tid för återhämtning men på att en tydlig återhämtning förekom.
Pellets - en framtidsmarknad?
With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods.
The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute.
2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.
Hundhållning i bil : situationen i Sverige och effekter av utetemperaturen. Enkätundersökning och experimentell studie
The aims of this project were to describe the circumstances around dogs being left alone in cars, to investigate owners? knowledge of the risks associated with leaving dogs in cars and the relevant legislation and, finally, to study how changes in the air temperature and air composition in the car affect the dog. The project consisted of a survey of the literature, a questionnaire part and an experimental part.
An important conclusion is the importance of the level of knowledge of owners, since there are several ways in which an owner can prevent their dog from heat stroke and, in the case of an eventual accident, their action can have direct consequences in minimizing the long-term damage to the dog and even whether or not it survives. Fewer than half of the owners in the study knew that for a dog suffering heat stroke, the most important thing is to bring the body temperature down. Only a third of dog owners knew that if a dog is left in a warm car and showing signs of heat stress, then the police should be contacted and the dog quickly helped out of the car.
Ett gott patientbemötande - en litteraturstudie om möjligheter och svårigheter
Introduktion: Anmälningar gällande bemötande till patientnämden är inte ovanligt, år 2010rörde ca 33 % av dessa frågor bemötande. Det handlade ofta om kontinuitet, att känna sigifrågasatt, inte lyssnad på eller trodd och om att inte bli behandlad som en individ. Syfte: Syftetmed denna litteraturstudie var att ta reda på möjligheter och svårigheter på vad som är ett gottpatientbemötande, ur ett sjuksköterske-och patientperspektiv. Metod: En litteraturstudie.Resultat: Både sjuksköterska och patient måste vilja skapa en relation med varandra. Att kännaförtroende för varandra och att patienten kände att sjuksköterskan var kompetent, visade sigvara en förutsättning och ledde till att patienten kände trygghet.
Habitat use and ranging behaviour of GPS tracked juvenile golden eagles (Aquila chrysaetos)
Throughout its wide distribution in the northern hemisphere, the golden eagle occurs in a diverse range of environments, e.g., mountainous, forest and open areas. The literature on juvenile golden eagles is limited, and this study provides further knowledge on habitat use and ranging behaviour during the post-fledging period in boreal Sweden. A total of 14 golden eagle juveniles were tagged with GPS transmitters during 2010 and 2011, and nine could be followed during the entire post-fledging period from fledging until migration.
The juveniles fledged at the end of July and beginning of August and initiated migration during October and beginning of November. The length of the post-fledging period, until migration started, ranged from 49 to 97 days. During this period, the juveniles? distance from their natal nest and their GPS height increased with time as their flying abilities developed.
?Jag är en vampyr? Om unga kvinnors identitetsskapande i det senmoderna samhället
The purpose of this Master?s thesis is to investigate if there might be a possiblecorrelation between young women´s fascination with the vampire narrative andtheir search for identity in the late modern age. With the help of contemporarysociological studies in the field of the late modern man and today?s youth culture,I?ve chosen to do qualitative interviews with eight young women in order to examinehow today?s society affects their process of identification. Lately we?ve been ableto see an enormous interest for books that deal with the vampire saga, and while thereaders are mostly young females, it brought me to ask the question why the combinationof teenage drama and vampires seems to be such a winning concept.We live in a time where most young females experience a lot of pressure trying to addup to the demands of society, and as the media keep producing images of youngwomen being thin and looking like supermodels, most teenagers feel a lot of pressureand anxiety trying to live up to such unnatural ideals that in the long run might lead tovarious health issues and eating disorders.As a result of this thesis I?ve found that the vampire narrative answers to some ofthe existential needs we have as members of a late modern society.
