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.

The aim of this study is to examine the significance of having a music department at the public library in Enköping, and how the organization of the phonograms is handled. The different areas examined are the reason of the reintroduction of a music department, its budget, its users, the work with selection, the marketing, statistical data concerning loans, the work with classification, indexing, and organization of the phonograms and the future of the music department. The empirical material consists of qualitative interviews with staff connected to the music department at the public library in Enköping. For the theoretical frame, Sanna Taljas discourse analysis of music libraries in Finland is used. Talja presents three discourses which all show different views on what kind of material a music library should contain.

South Africa has been among the top ten wine producing countries for at least 20 years. Even though the land under grapevines is decreasing globally it is still increasing in Africa. The awareness of environment has strengthen the last years and South African producers experience a high demand of environmentally friendly produced wine, especially from the European market. This demand was the driving force behind the development of the world unique sustainability certification, Integrated Production of Wine (IPW), which is inscribed in the South African legislation. What makes this certification unique is that consumers can trace their product all the way back to the farming practices owing to the identity number specified on the IPW Integrity & Sustainability seal on certified products.

I den här uppsatsen har faktorer för en ökad användaracceptans och diffusion av Video on demand(VOD)-tjänster identifierats med hjälp av en litteraturgenomgång av tidigare studier i acceptans och diffusion. Litteraturgenomgången ligger till grund för en lista av faktorer som gör en konsument mer villig att anamma en VOD-tjänst. Faktorerna har sedan utvärderas genom en kvantitativ undersökning med hjälp av en webbenkät. Resultatet blev i stor grad det som förväntat där det framgår att utbud och kostnad är de viktigaste faktorerna för en hög acceptans, men även andra faktorer kan spela in som användarvänlighet, kvalitet och sociala faktorer..

This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

Due to fast growing and rapid changes in markets today, most of the organizationsthat are trying keep up with these changes have a high demand for software that areof high quality and comes with a low price. To meet these goals software companieshave to implement new methods to develop software that are suited for rapidchanges. The concept of agile methods can fulfill this need. Our purpose with thisthesis was to investigate how well agile methods could be applied in organizationsthat could be identified as adhocracies. A case study was conducted in anorganization which we could identify as an adhocracy.

This thesis investigates the socio- and environmental economic effects of a deep repository for spent nuclear fuel in Forsmark in the municipality of Östhammar. I seek to show the general picture but focus on the effects on employment, environment and income. Cost-benefit analysis is used to investigate the differences in utility between a scenario with and a scenario without a deep repository in Forsmark. Most of the possible effects can not be valued and many can not even be quantified with the data available today. Therefore this thesis has a bit of a ?preliminary study character? and seeks to show what we know today and what needs to be further investigated when available data allow it. The costs that could be valued are noise from the traffic during the period of building and emissions of carbon dioxide and nitrogen oxides from the transportation of rock masses during the building period.

Does goodwill affect the cost of capital? Goodwill is an asset which is characterized by much uncertainty regarding both what it is and how much it is really worth. Based on economic theory about information risk and principal-agent problems as well as theory regarding the cost of capital we test for the hypothesis that debt and equity investors perceive goodwill as something risky and hence demand compensation for taking on this extra risk. The proxies used for the cost of capital are cost of debt, beta and the EP-ratio. On a general level we find that increasing the level of goodwill seems to result in higher cost of capital as represented by the three proxies.

Problem: Konkurser drar med sig höga kostnader på olika sätt, och genom åren har många försök gjorts att finna modeller som kan förutse konkurser och därigenom undvika dem. Några av de mest beprövade modellerna är Altmans olika Z-scoremodeller, som genom åren visat olika resultat. Allt fler företag blir också verksamma inom tjänstesektorn, och forskningen menar att dessa företag skiljer sig från tillverkande företag när det gäller dess nyckeltal, vilket alltså borde påverka möjligheterna att förutse konkurser enligt de modeller som idag finns.Syfte: Kontrollera huruvida Altmans Z´´-scoremodell fungerar på små- och medelstora tjänsteföretag i Sverige, men även om korrelation mellan ett företags kreditbetyg och dess Z´´-score föreligger.Metod: Uppsatsen är skriven utifrån ett positivistiskt synsätt med deduktiv ansats, och bygger på kvantitativ sekundärdata. Analyser görs genom hypotesprövning.Slutsats: Altmans Z´´-scoremodell fungerar dåligt på tjänsteföretag inom segmentet små- och medelstora företag i Sverige. Resultatet blir detsamma, även om modellen tillämpas på    tillverkande företag och handelsföretag.

The EU has had a special agreement with their former colonies in Africa, the Caribbean and the Pacific Islands, the ACP-countries, for almost 30 years. This has granted the ACPs with preferences on the Europen market, which have been excluded from other countries. The agreement is now beeing re-negotiated to make it more in terms with the rule of the WTO?s most favoured nation-principle. The new agreement will differ from the present one as it will be a mutual free trade agreement where the ACP countries will open their markets to the EU as much as the EU opens up it?s market to them.

In the informational age of today, continuous learning is of greatest importance. The demand for this seems to be increasing, while at the same time people are under more pressure to carry out more tasks in shorter amounts of time. A way to solve the problem of finding time to learn could be to make use of the possibilities that Internet offers for learning at a distance. The purpose of this thesis is to, from a pedagogical perspective, contribute to the discussion concerning Internet based distance education for a target population consisting of professionals. We have found that some of the courses included in the two certification programs which we have investigated are suitable for Internet based distance education.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

One problem in today?s indoor air quality lies within insufficient ventilation. Dynamic ventilation can be obtained by implementing a Demand-Controlled ventilation (DCV) system. DCV systems adjust the ventilation in a building by calculating the impact made by its? occupants.

The purpose with this research is to examine how the green marketing in retail trade can be developed in order to promote the eco-labeled products closer to the consumer.The method for the survey includes interviews with managers of a few retailers and their customers in the industrial sector. The purpose with the interviews was to produce the retailer and the customer?s perspective of products with eco-label on.The research is limited to the region of Västra Götaland.The results from this research indicate that there is a lack of communication between the retailer and the consumer. The consumers don?t think that the product is available.
