VINDKRAFTSETABLERINGAR : EN JÄMFÖRANDE STUDIE OM NÄRBOENDES INSTÄLLNING TILL VINDKRAFT OCH VINDKRAFTSETABLERINGAR I SVERIGE OCH BRASILIEN
To achieve a sustainable development, three aspects have to take equal place in the society; environmental, economical and social. To reduce the impact on the environment and the amount of greenhouse gases supplied to the atmosphere, industrialized countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase.Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is abundant and available worldwide.Examinations made in Sweden, indicates that there are difficulties establishing wind power at the same pace as the environmental goals, set by the Swedish government, requires. Mainly because people living nearby potential areas for wind power farms, appeal against the decision.This study aims to investigate differences between how people in Sweden and Brazil look at wind power as a future energy source and at the establishing process.
Män i tights och kvinnor i byxor : En kritisk undersökning av hur film kan användas i historieundervisningen för att lära eleverna studera förändringar i genus och hur dessa kan relateras till sin samtidskontext
Film is a tool frequently used by teachers, but it is often limited to showing students how historical time periods looked like, or as a way for students to search for historical inaccuracies. The aim of this essay is to study whether it is possible to use two films based on the legend of Robin Hood as a way to teach students how to contextualize gender history. Through the use of film analysis and gender analysis of two different versions of Robin Hood, The adventures of Robin Hood and Robin Hood: Prince of thieves were analyzed. The study has shown that it is indeed possible to use film as a source material for the study of gender history, and that film can tell us a lot about the contemporary view of gender, masculinity and femininity. The didactical analysis concluded that there was no theoretical objection of using film as a source material; however, there are some things that a teacher should be aware of. Although film may be a good way to create a varied study environment and benefit students with reading- and writing disabilities, there is a risk that time-constraints and lack of knowledge of film and its methodology on, behalf of both teachers and students, may make it hard to implement.
?Det sade bara klick?: en studie om 15-åriga tjejers Internetanvändning utifrån ett källkritiskt perspektiv
This Masters thesis aims at investigating how 15-year old girls use the Internet, particularly on their free time, taking a source critical perspective. It includes group interviews. The main question of this thesis was whether there is a need for specific user education. The following four questions were asked: What do they do on the Internet during their free time? In what way do the girls learn how to interact with each other on the Internet? How do they relate to different types of web pages and materials from a source critical aspect? What content do they consider to be relevant in a user education? The study is mainly focused on information use and information behaviour in different contexts.
Ingenting är sant, allt är tillåtet : En kvalitativ studie om historiska datorspel som Assassin?s Creeds påverkan för det oavsiktliga lärandet och dess pedagogiska möjligheter
The main purpose of this study is to investigate the unintentional learning that happens during the use of computer games. With the use of interviews with students in the ages 13-15 who all have played the game series Assassin?s Creed, and then compared them with students who does not play the game, we have been able to identify that some learning is taking place, but that the student?s attitude towards the subject, and their maturity, also is vital for the learning. Even tough, the students who didn?t really enjoy history as a subject showed better knowledge after playing the game, than the students who hadn?t played at all, which indicates that computer games can be a good source for learning.
Energieffektivisering i ett verkstadsföretag : En analys av energibesparande åtgärder samt uppvärmnings- och kylsystems driftkostnader och koldioxidutsläpp
The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.
Den gränslösa samlingen: de fria webbresursernas plats i beståndsutvecklingen på några svenska forskningsbibliotek
The aim of this master's thesis is to describe the management of free Internet resources in three Swedish research libraries. With the starting point in the increased quantity and importance of these resources, together with reflections on the change of the concept of collection, the thesis shows how and to what extent these freely accessible Internet resources are being integrated in the day-to-day work with collection development. It also elucidates the problems with the free Internet resources from the research libraries points of view. The study is based upon analyses of collection management literature and qualitative interviews with librarians at the chosen libraries. The thesis shows that the research libraries still have not come very far in their work of integrating the free Internet resources in their collections.

Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.
The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.

...de bultades till bättring : till frågan om Sveriges kristnande
The written sources concerning the process of christianization in Sweden has for a long time been limited to two main texts, Rimberts vita of St. Ansgarius and Adam of Bremen´s History of the bishops of Hamburg. This is due to a rigid source criticism in the beginning of the 20th century, which put other material ? in particular the norse sagas ? out of consideration. The last twenty years however, new questions have been raised concerning the christianization, partly because of new archaeological findings, new interpretations of the significance of runic stones and the recent debate about the formation of the Swedish medieval kingdom.
