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.

We have from three studies examined how adolescents and young adults, actors and the researchfield describes the preventive and health promotion work with sexual health. The questions weasked ourselves was based on what efforts adolescents and young adults demand, whether there aredifferences between age, gender, place of residence, ethnicity, employment, and sexual orientation.Furthermore, we investigate if these requirements are consistent with the offered interventions fromparticipants, as well as which perspectives the work with STI / HIV and SRHR issues should bebased on. The investigation concerns the work of Västra Götaland and is answered by interviewswith participants regarding the activities offered by actors, a quantitative analysis and text analysisof the answers of adolescents and young adults, and an international research overview of theresearch field. Our results show a high demand for basic preventive work from the adolescents andyoung adults. Furthermore, there is an increased demand of action from men, LGBTQ group anddepending on the place of residence.

The bioenergy market has been introduced relatively late in a perspective of the Swedish forestry. Nowadays branches and tops are used more frequently as bioenergy after harvesting. Therefore, it has developed a competitive situation between pulpwood and bioenergy. This situation has even established some questions. Two examples of these are: ? At what top diameter should the final piece of pulpwood be crosscut to get the best economically result? ? Should the top diameter, at the final piece of pulpwood, be crosscut at a thicker or smaller diameter than what is done today? The purpose of this report is to answer these two questions when the harvesting is made motor manually in beech stands.

Many studies have been conducted of different types of business networks in recent years. Despite this, there is a lack of research concerning industry-transcending formal networks which are limited to a specific region. We have conducted a case study of Örebro Promotion, which is an industry-transcending network including over 500 members. Örebro is a medium-sized city in the middle of Sweden. The purpose with our study is to create an understanding of why enterprises choose to be a part of the network and what they feel is the gain of their membership.

This paper is a comparing study of the retrieval effectiveness of the search engines Google, Google Scholar and Scirus. The aim is to find out how good they are at retrieving relevant academic material in the research-field of Library and Information science. The thirty search questions where based on actual information needs collected from exams within the field of Library and Information Science. This method was used to prevent that none of the search engines were given an advantage because of construction of the information needs. The first twenty retrieved documents on the retrieval lists are examined for academic content and relevance.

Digital preservation is a relatively new subject to Swedish archives. Alhough computers have been used for a long time, preservation has been made on paper and stored on shelves. These days a lot of cities in Sweden have investigated how to best secure the digital information for the future through electronic archiving, e-archives. One option is to hand in the information as soon as possible, but to let the producer keep the information ownership yet some time. The idea is to let the producers of the information answer questions and hand out material, since they are more competent on their field.

In these days we can witness a growing number of combined school and public libraries in Sweden. It can be explained as an economy measure or as an attempt to develop the library work. The aim of this thesis is to picture how working in combined libraries affects high school librarians? own apprehensions of their professional identity. The results are based on in-depth interviews made with four high school librarians, working not only towards the students but also the public.

The aim of this work is to gain understanding of how predictions and images of future are created and maintained and how they are changed in society. An interdisciplinary approach to cultural and social aspects is used to examine how collective images about future are created. The distinction between collective images and private images is problematised. The subject matter is extracted from a previous explorative examination about Do It Yourself and OpenSource culture which are concepts of collective learning. That work is described in the foreword.The question ?How is a collective image about the future created?? is central for this paper.The interdisciplinary approach is a cross reference synthesis of philosophies, educational studies, film studies, strategicstudies and future studies.

This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.

This essay aims to explore the philosophical meaning of the expression ?present and real? in Clara ? or, On Nature?s Connection to the Spirit World by F. W. J. Schelling.

This essay explores to what extent the Swedish language version of Google Images meets the usability requirements of average everyday users. Previously published studies on user behaviour and users? interface and search option preferences define the usability requirements, which are matched against Google Images? actual interface and search options. The retrieval method of Google Images is also briefly discussed, and users? opinions about Google Images too, as they come across in the previously published user studies.The findings are that Google Images lack some of the things that users ask for, but it still seems to be the most used image search engine among average internet users and more appreciated than other search engines.

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

Eutrophication is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution. The purpose of this study was to investigate how the relationship between phosphate solubility and pH was affected by liming.

In forestry there are always needs of forest data to make good strategic decisions of different actions and economic winning. Usually this data gets from field-estimations made by forest workers with expensive costs and sometimes unsatisfied quality. StoraEnso Skog is a great forest company in Sweden and they have part of the responsibility of the forest own by Bergvik Skog. Bergvik Skog is owner of 1, 9 million hectares productive forest land. Both Bergvik and StoraEnso have great interest in new inventory techniques to get the important forest data. The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna.

This study is based on interviews with six students from Stockholm that have shared their feelings/opinions about how they experience their identity as a student. The aim of this master?s thesis is to examine how the identity of students is constructed but also how the post modern society affects the life that the students are living. With a higher demand on education and responsibility of making the right decisions, the student?s main concern is not only her studies, but also the goal to succeed in her life.
