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.

This thesis has been done at the Unversity of Örebro for Örebro University Hospital (USÖ). In our work we have developed a product for hearing tests to determine hearing thresholds of small children. Our product contains software and a control surface for controlling two separate screens. One of the demands was that our software could handle big file libraries. Reliability and simplicity were essential for the user.In our work we have utilized programming of both microcontrollers and Windows software.

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.

ABSTRACT Our main objective with this essay is to provide a description of old people?s stories about aging. The essay is based on the empirical source of four qualitative interviews with older people over the age of eighty years young. The main goal is to inquire answers about; their time in the workforce; retirements; healthissues; media/advertisements; adolescence/youthfulness and attitudes. The following main questions have been dealt with: What do the elderly emphasize when they describe ageing? Are healthissues the prime subjects the elderly talk about? Do the elderly experience positive or negative attitudes towards ageing? What is their point of view of younger generations? In what way do they describe their years as workers? In what way do they describe aspects about their retirement? We reserved to consider the opinion of their own, to be the most valuable source in our study.

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.

The purpose of this thesis is to study and determine how working in cross functional teams can generate value in an effort to facilitate innovation. An inductive scientific perspective is chosen as the research approach. A single case is investigated with the theoretical framework based on Resource Based View, Intellectual Capital, Innovation theory and theories concerning Cross Functional Teams. The empirical material has been collected through primary data; surveys, interviews and secondary data; literature, websites and further complementary data. The practice of using Cross Functional Teams will enhance organizational learning, knowledge transfer, increase communication and innovation, which in turn will increase the speed and performance of the new product development process.

The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.

The aim of this bachelor thesis is to see how illustrators and illustrations are treated in Bibliotekstjänst?s binding booklets compared to how authors and texts are treated, i.e. the picture versus the printed word. My aim is to try and find out if librarians have the aids to acquire information about picture-book illustrators and illustrations in their selective work and reference work. In order to find out about this I need to examine the most common aid in this work, i.e.

The aim of this thesis is to gain a deeper understanding of howsocial contacts can serve as information sources for pregnantwomen. Furthermore, we wanted to examine how women?scontext influences their information seeking and the barriers thatcan occur during information seeking. The theoretical frameworkis founded on Tom Wilson's model of information needs as contextdependent, and Pamela J. McKenzie's model of informationpractices in accounts of everyday-life information seeking.

Skärgårdsstiftelsen, which is responsible for several of the archipelago islands in Stockholm, has chosen to explore the possibilities for more sustainable heating systems in buildings on the islands in collaboration with KTH. A reduction of energy use and improving the efficiency of existing heating systems are included as part of the environmental work. This report studies the island of Grinda, which is located outside the area of Vaxholm in Stockholm. The study area consists of a guesthouse consisting of a restaurant as well as conference facilities and four neighboring cottages used for overnighting. The cottages now run solely on direct electricity, both for heating and hot water.

The essay has its beginning in the source material that deal with ancient Norse religion before the people in the Nordic countries became Christian. The fact that there are no contemporary written or authentic sources available that can tell us something about the Norse religion during the Viking age is problematic. Archeological source materials is available, but tend to talk more about power relationships and social status than the old Norse religion and the way people practiced their faith. Medieval Christian writers are a source of knowledge of the Norse religion; however, they can only highlight the Norse religion from a Christian point of view and ways of evaluating the pagan faith, making them less reliable.The written sources of this paper are based on the written by two medieval Christian writers, Saxo Grammaticus and Snorri Sturluson. These sources are among the first to treat the Norse religion process after the introduction of Christianity in Scandinavia.
