Från föhn till feu! : Esrange och den norrländska rymdverksamhetens tillkomsthistoria från sekelskiftet 1900 till 1966

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

Import av avfall för energiutvinning ? en systemanalys av avfallshanteringens klimatpåverkan

This study has examined if importation of waste for energy recovery can reduce the climate impacts of Waste Management Systems. Using Systems Analysis this study will try to examine the complex waste systems in a systematical and strictly logical way to see how these systems interact and affect each other. Specifically examining the climate impact of waste management systems in England. The traditional way of handling waste in England is through Landfills. Land filling leads to emissions of the greenhouse gas Methane. The EU has put in place a landfill directive that is supposed to lead the member states away from land filling as a method of waste management. Today in Sweden there is a competition for the waste available for incineration. The worsening economical situation together with less product packaging and an increase in source separation leads to a lack of waste available for incineration.

Tio år med stadsdelsreformen i Göteborg med omnejd. Synpunkter hos anställda vid sex folkbibliotek och inom kultur och fritid

This is a comparative study of six public libraries in the city of Gothenburg and its neighbourhood. The main purpose of this master thesis is to describe these libraries relating to a reform in the city council of Gothenburg and its neighbourhood. The comparison deals with a period of ten years, 1990-2000. In order to respond to this I formulated two questions: Are there any differences in the activities of these libraries? Has this reform influenced the librarians in their way of working and if so, why? I have studied relevant literature such as annual reports, investigations and analyses in order to be able to formulate the questions.

Anpassning av passivhus för ett kallare klimat - teknisk och ekonomisk analys

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Landet Kris : - en kvalitativ undersökning om hur Lettland framställs i svenska nyhetsmedier

The purpose of this study was to find out how swedish newspapers writes about Lettland during 2005-2009, who gets to speak in media, which key words being used, and if the news articles content changes over the years. As a basis for my discussion I?ve used Stuart Hall's theories for representation and language. In the same litterature, Hall presents theories for stereotypes and power from different researchers which I have studied for this study. I?ve also used Van Ginnekens theory about who may be heard in media.

EU:s påverkan på västra Balkan : Det regionala samarbetet Ett fall av europeisering?

The general aim of this paper is to describe how the European Union can affect and transfer their conditionality politics to the Western Balkan countries. A specific purpose of this study is to describe and explain what we in this paper consider to be a specific additional membership criterion, regional cooperation that has been especially designed for this region. The point of departure for this paper is Europeanization theory that will be used to study the European Union?s impact on non EU-members in Europe. The theoretical Europeanization mechanisms are taken from Heather Grabbes ?Europeanization model?.

Muay thai: barn som utövar Thailands nationalsport

The purpose of this study was to describe and analyse the living situation of children who practiced Muay thai at two different Muay thai schools in Thailand. The metod I chose was participation studies with the compliment of open interviews. My main questions were to see if and how the children were affected physically and mentally by the training and possible matches. I also wanted to see if Muay thai practiced by children could be considered child labour, reasons why the children did Muay thai and what opportunities Muay thai gave the children in other parts of their lives.My conclusions were that the training gave the children an overall god physical status, and did not affect the children in any direct negative physical way. Mentally the main affect on the children in training were the stress of not being allowed to eat before matches.

Kvighotell

In this essay I have summarized important factors for an effective, but also successful, way to raise and house heifers. This study can be used for other dairy farms to use as guidelines in their process to raise heifers. To let outside heifer growers house, feed and have the heifers pregnant before return, can save a lot of work. But also moneywise, when the care and individual programs makes them strong and increases the growth.The result is a faster breeding and an earlier time for their first calving.In Sweden the heifers tend to be older if you compare with Denmark or United States where the custom heifer raising is well known and growing. One reason can be the Swedish laws regarding outside grassing for all cows during the summer months.

Folkbibliotekets roll i det lokala samhället ? Tre kvalitativa fallstudier

The aim of this master?s study is to examine the function of the public library in the local community at present. I have searched for the answers to the following questions: Which position has the public library in the local cultural policy? What characterizes each library and which are the priorities? What is the local profile of the public library? What cooperation partners does the public library have and what do they mean to the library? Does the public library intensify the local community in any way? To answer this, I have made three qualitative case studies. Interviews and collection of documents were carried out in three different communities.

En ?vergiven torpmilj?. Materiella och immateriella l?mningar fr?n torpen kring Brunnslid i Kinneveds socken, V?sterg?tland.

This essay presents an investigation of the ruins of an assembly of crofts in a rural area in the south of Sweden, outside the town Falk?ping. Using literary sources and intangible sources, and then combine them with the information found by investigation of the physical remains of the crofts, the essay attempts to capture the life and the living conditions of the crofters. The investigation is focusing on the period between the nighteenth century and the first decades of the twentieth century, and looks into the the living conditions according to, for example, the buildings, the orientation in the landscape, demografical changes, the transformation of the area over years and how the crofters were affected by powerty. The investigation shows that the crofters in many ways were in vulnerable and exposed positions, powerty summarized as a lack of freedom ? concerning economical, political and social dimensions.

En jämförelse avseende beståndsgående-och stickvägsgående gallringsmaskiner

The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand. The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted. The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages. The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent). Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated. Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same. However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time. If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..

Givarkonstruktion för beräkning av sådjup

This report shows the process of the development of a sensor module for the seed drills of Väderstad Verken AB. The module is supposed to replace existing solutions, provided that it is better from both a constructional- and an economical aspect. The purpose of the sensor is to continuously give the driver information about the level of height of the front- and drilling tools and the main purpose of the sensor is to allow the seeds to be placed at the desired depth. The sensors which have been taken into consideration have all been of an analogue type and have a protection class of minimum IP67.The methods applied have been taken from the book ?The Mechanical Design Process? by David G.
