The aim of this master thesis was to find and grade suitable sites for wind turbines in the rural district of Lerum at the reguest of Göteborg Energi. The rural district of Lerum consists of very complicated terrain which was the reason why we picked Lerum.The assignment was achieved by using the software program ArcGIS and its attendant tools. In step 1 an overall analysis was made in order to sort out the least suitable sites. Step 2 consisted of a 3D analysis in ArcScene together with a more precise analysis in ArcMap. As result we found two interesting sites, which met our demands and specific constraints.

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.

The program is capable of generating graphics for a majority ofthe cases.

The aim of this Masters thesis is to examine the library discourses concerning the phenomenon and concept of digital libraries in Swedish library press 1980-2002. What changes can be identified? The questions are: what is said about the conditions for the phenomenon; how is the concept of digital libraries used; who makes these statements; what are the relations between these discussions and the library context in which they are made? Five Swedish library journals, BBL/Biblioteksbladet, DIK-forum, Human IT, Svensk biblioteksforskning and Tidskrift för dokumentation, were examined. The method used was discourse analysis. The theoretical starting-point was Foucaults discourse theory.

Med detta examensarbete vill vi belysa problematiken runt tredimensionell fastighetsbildning. Som objekt har vi använt oss av ett bergrum på Liljeholmskajen i Stockholm..

Abstract The use of electronic media plays an important part in the life of youth and especially Internet and mobile phones are important in the social and cultural networks of youth. The first step of this thesis is to examine the ICT-based activities of upper secondary school students through an online survey. The second step is to examine what didactic implications can be derived from the ICT-based activities in the subject of Swedish. Results from this survey and national and international research show that young people spend the majority of their leisure time on the Internet. The result also shows that media activities displace other school related activities such as traditional reading and writing.

The purpose of this thesis is to examine how social workers perceive the concept of knowledge within social services, particularly within children and youth services. Our goal is also to study the employer's expectations and demands on graduate social workers. The main questions we address in this thesis are; What knowledge is seen as useful by employers and graduate social workers working in social welfare offices? To what extent does university education bring useful knowledge to the work being done by social workers? What practical knowledge is there in the workplace for social workers to learn? When recruiting, what expectations does the employer have of graduate social workers? What challenges are there with recruiting a graduate social worker?We have interviewed six social workers and four employers in the social childcare division in different municipalities in Skåne region, Sweden. We have used epistemology in our analysis.

Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.

First of thetheories that are considered canonicalfor high tech business development wasexamined. The next step was to go into the role of a business developer inone of the hottest high tech materialinnovation startups this decade,Disruptive Materials.

The animal welfare act in Sweden states that dairy cows need to have at least a dim light present at night, but there are no recommendations for what intensity the light should have. It is unknown how cows perceive and react to low light intensities and earlier studies on this topic are limited. Red light as night light has also been suggested, based on the cows? inability to perceive red light. This have however been questioned. The aim with this study was to investigate how four different light intensities affect dairy cows behavior.

Generally, the economic health of Swedish roundwood truck transport companies has not been good. Profitability is important for maintaining the stability in the transport business, which is a condition for long-term transport planning in the forestry sector. The scope of this study was to identify probable factors influencing the profitability of roundwood truck transport companies and quantify the influence of these factors on economic results. The study was carried out at a major roundwood truck transport organisation in mid-Sweden and was implemented in four steps. In the first step economic results from the haulage contractors were collected and a random sample was taken from accounted net margin for the account year 2005/2006. In the second step hauliers were interviewed to identify probable success factors. At the third step data for identified factors were gathered through a questionnaire.

The purpose of the study was to investigate the use and losses of energy in an existing older building. Another purpose was also to look through various options for heating systems with renewable energy in the building. The aim was to reduce the use and losses of energy. The first step was to study the related electricity bills of the building and also perform measurements and calculations of the building envelope and ventilation. The next step was to find out the possible actions for energy saving by performing measurements and calculations.

The aim of this master thesis is to describe some general trends and important steps in the Swedish university libraries user-orientation from the implementation of the university college reform 1977 until today. The aim gave rise to four further questions. Literature studies and empirical studies in the form of focusing interviews have been carried out, in order to answer the questions. Of the entire background material I have made a simple form of general analysis. I found that the libraries, during the years have interacted with the following four interested parties, the government, the mother organization, other libraries and the library users.
