The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

Previous work by researchers as Eugene F. Fama and Kenneth R. French, show that average return on stocks are related to a firms characteristics like size and book-to-market ratio. These kinds of patterns in average return is not explained by The Capital Asset Pricing Model (CAPM), and are therefore seen as anomalies. Fama and French have proposed a three-factor model, which captures patterns observed in U.S average returns associated with size and value.

The main purpose of this Masters thesis is to examine gender division in public libraries by reviewing literature and interviewing eight public librarians and two chief librarians. The reason why we decided to investigate this topic is the lack of research concerning sex-segregation in library and information science. By choosing this subject we intend to deepen the understanding of the significance of gender both within the public library and of the occupation in general. Some researchers claim that the low status of librarianship is a result of the large proportion of women in the profession. We want to find out how our informants view the relation between professional status and female domination.

AbstractThe customer demand for ecological products has increased in recent years, within the garden industry this mainly concerns herbs and other edible plants. The organic trend is increasing and more people are aware of the environment and want to take responsibility for it through their purchases for their garden as well.In this essay the aim is to investigate customer demand and the possibility of selling organicperennial plants in eight garden centres on the Åland islands and in Gävle/Sandviken. I include two garden centres with an organic profile to get a wider point of view. I investigate the global market for organic perennials and look further into existing certification standards on the Swedish market today.The methods I have been using are interviews and a literature study.The study shows that the experienced demand for organic perennials is small in both of myinvestigated groups. The biggest motivation for starting to sell organic perennials would be to find a supplier of these plants and that more customer would ask for them.

Previous studies have shown that there is a relationship between voluntary disclosure and analysts' forecast accuracy. However, there has been no research conducted specifically on bridges. Bridges contain information on how components such as price, volume, foreign exchange rates and acquisitions have impacted the financial performance between two periods. The main purpose of this thesis is to investigate the usage of bridges in quarterly financial information of companies listed on Nasdaq Stockholm. We provide a descriptive mapping of bridges and find that 30 out of 268 companies are presenting bridges as a part of their voluntary disclosures, with large firms being the most frequent users.

The aim with this thesis is to highlight components regarding small children?s reading environment in preschool and see how these affect their meeting with literature. The study is based on J. A. Appleyard?s theory on man?s development as a reader.

The aim of this thesis is to examine librarians' view on the knowledge and competence required at a small public library and how they look upon their education in retrospect. Library education in the 1970's and 1980's was mainly practical, a vocational training, but since 1995 the education results in an academic degree in Library & Information Science. Due to this, we focus on the ongoing generation shift in Swedish libraries as an aspect of knowledge and education. The empirical study is based on interviews with librarians working in minor public libraries. The informants form two groups, based on their education; ?old? ones and ?new? ones.

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.

The purpose of this work is to find out if the suctionvalve to the salivaejector for dental equipment in a simple way can be improved or if a new design is needed. The result of the examination of the suctionvalve shows that the friction between the piston and the seal is high and that this causes the valve in a few cases sheaves. The study concluded that only small changes in material or detail, improve the component..

Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.

Background: Increasingly, companies choose to finance their business with corporate bonds which has resulted in an increased demand on credit ratings. As such the rating agencies have a very important role in the financial markets. Examining the value of a credit-rating can be very interesting for both issuer and investor. Purpose: The purpose of the study is to identify and define the value of rating. Execution: The study is built upon nine interviews with rated and non-rated firms and investors.

The interest in businesses active on the countryside and their funding situation has increased in recent years. In a survey, conducted by Leif Berndtsson (2003), it was reported that there is a lack of external capital in rural areas. According to Berndtsson (2003) the lack of external capital inhibits the rural firm?s growth. The essay attempts to answer whether the shortage of external capital is a factor that inhibits development for rural businesses.
