ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.

Competence is a complex concept that encompasses many facets. This study aims fora better understanding of the concept. Many branches of business administration science would benefit from a better understanding of competence and, through that understanding, find solutions where competence is one of many variables. By combining a positivistic and phenomenological approach, this study has created a broader understanding of the concept of competence.The study combines systematic study of the relevant literature with in-depth interviewswith people representing both the employer and the union within the staffing company world.The results show that quantifying competence is a complex and next to impossible task, as it would involve including the whole concept of competence in the calculations. When this is done, the phenomenon itself becomes so complex that it loses its validity.This is why theorists who want to perform this type of calculations put most of the competence complexity in ?the black box?.

The main goal with this thesis report was to come up with ideas of how to make the use of energy more effective and thus save money for the company.First a survey was made to find out where and how the energy consumers were divided within the company. The results were then used in calculations to find out how much money that could be saved and how long it would take to get back the investments.There is a big potential in saving money by recovering heat from the UV-lamps with a heat exchanger. It would also even out the pressure in the factory which is a source to heat loss and a cause for discomfort amongst the employees. It?s possible to save 105 000 kr in a year and the money needed for the investments is 600 000 kr.By using the recovery air more effectively the company could save up to 250 000 kr a year in lowered heat purchases, but this would require the use of automatic dampers.If you reschedule the running times for the wood chipper and invest in some kind of load management, for example Sydkraft?s ?Energidirigent? you can save at least 42 000 kr.

This project is based on my fathers farm which lays outside Löberöd, twenty kilometres south of Eslöv in Skåne. While my family for some time have thought about building a new milkingstable with AMS(Automatic milking system) I decided to compare the AMS with a conventional milkingstable. We are abit concerned about how many cows we should have in the new stable. Because of that I calculated with two different number of cows. I have compared three different types of milking stables: One alternative is 180 cows milked in a double eigth hearing bone milking stable. The second alternative is 128 cows milked with two DeLaval VMS-robots. The third alternative is 171 cows milked with three DeLaval VMS-robots. One salesman from DeLaval and one salesman from A-betong helped me to get marketprices on the milkingrobots, building, ventilation and prices on all the concrete. In all the costs labour is included. The rest of the costs are calculated in a softwareprogram called K-data 03 which is a program with predicted costs. The calulations from the program showed that the price in the milkingpit system was 51 000 sek per cow.

Background: Corporations are established and organized in order to create economic values for their owners and the main aim of every business enterprise is to be profitable and satisfy the financial expectations of their shareholders. However, corporate social responsibility focuses on the ethical aspects of corporate business in order to achieve the balance between the profitability and social responsibility. Nongovernmental organizations through their activities promote the respect for human rights and environmental care within the corporate world. Purpose and Scope: To make an in-depth study about the role of nongovernmental organizations regarding corporate social responsibility in order to increase the understanding of corporate social responsibility. Methodology: We used literature research for our thesis and we analysed the secondary data related to the corporate social responsibility.

Volvo in Arvika produces wheel loaders, and the production is based on forecasts. When a machine is ordered, the customer can choose what type of equipment he or she wants, and these equipments are also made forecasts on. This is made by giving each equipment an estimated procentual usage that shows how many of the machines that will use this option. Today two people are working with the forecasts, planer A in Eskilstuna and planer B in Arvika. Planer A makes a forecast based on the historical outcome and planer B then makes adjustments of this based on how many options that are ordered.

The purpose of this thesis is to contribute to a further understanding of the complexity in green consumer behaviour by examining how and why individuals priorities values, personal norms and identity in green consumer behaviour. The thesis employs a qualitative approach with an abductive strategy. The empirical data was produced through in-depth interviews with green consumers. Based upon the empirical findings and theoretical concepts, a conceptual model was introduced to illustrate how consumers prioritise between several values when assessing green products. The prioritisation is dependent on internalised values as well as the product function and the need that the consumer seeks fulfilled.

Researchers and practitioners have recognized the need for ?transforming? every policy of the company into a competitive advantage tool. Thus, both the pricing approach and the supply chain practices of the firm have emerged as an important determinant of success. In this study, however, we are not only interested in these two aspects, but also in a third one-namely cultural conflicts as an obstacle and challenge. The interaction of the tree factors is extensively presented against the backdrop of Skanska and four of their closest Polish suppliers.

The aim of this study was to describe non-surgical treatment options for the diseases mucositis and peri-implantitis found in present literature. The literature review also illustrates the effect of the treatment opptions on soft tissue with mucositis and peri-implantitis surrounding dental implants. The study reviews twelve scientific articles that have been processed from the aim of the study. The result shows six therapy options, Er:YAG laser, air abrasive, ultrasonic device, hand instruments, hand instruments in combination with antibiotics and hand instruments in combination with clorhexidin. The following methods are described according to how they are used and how they affect the soft tissue surrounding dental implants.

The cocoa produced in Fiji is exported to industrialized countries for processing of the raw material. The Swedish organization Cocoa Bello is involved in a project to provide the Fijian cocoa farmers with knowledge as well as resources to enable local processing and to attain added value of the cocoa crop. The purpose of this study is to discover a field of application for the Fijian cocoa among the rural population, using an ethnographic design. We spent one week in Namau Settlement, Fiji, where we applied in-depth interviews and participant obser-vations in six families. We found a number of aspects affecting food choices, such as social, economical and cultural beliefs.

Hedge funds? importance within the financial system has during the most recent years increased dramatically. These special funds are unique instruments that differ from traditional mutual funds in a variety of ways, however especially in how they expect returns. Due to the fact that hedge funds are able to hold short positions they possess the possibility to become market neutral investment vehicles.Because of this possibility to sustain positions neutral to market fluctuations, the concept of absolute returns became a unique selling point for hedge fund managers and promises of stable returns unchallenged by market conditions was assured. This research paper aims to examine the theory of absolute returns in hedge funds by examining hedge funds from the Nordic region during the last years of economic turmoil that has occurred by  analyzing the results from their strategies, partially by quantitative measurements as well as qualitative.  The results show that none of hedge fund strategies managed to deliver absolute returns over the chosen period..

The debate in the media on a new Swedish sex education movie sparked our interest in this study. The twenty-eight minutes long movie ?Sex on the map? is the first of it?s kind in twenty-five years. It is also part of a bigger sex educational project that contains, apart from the movie, a book about sex education, a documentary and a teachers guide. The project is a co-production between the Swedish Educational Broadcasting Company (UR) and the Swedish Association for Sexuality Education (RFSU).We were interested in how teachers received information about the project, and what their attitudes were towards it.

During the 19-century a global warming has been observed, which includes increases in global air and ocean temperatures, widespread melting of ice and snow, and rising global sea level. There is a clear connection between emissions of greenhouse gases caused by the human and the increase in temperature. Climatic changes caused by global warming can be stopped trough decreased emission of fossil fuels, for example by an increased use of biogas. Biogas is a renewable energy source which is produced through anaerobic (oxygen free) digestion of organic material. The gas is a mixture of methane (CH4) and carbon dioxide (CO2) and can be among others used as fuel in vehicles.

In this study we are focusing on Instagram and marketing. We want to know how Web 2.0 and social media creates a new place for companies to market themselves and mostly how they are using the social network Instagram. The amount of swedes using Instagram is 28% and that is the double of what it was a year ago. This creates a whole new place for companies to market themselves and most importantly; it?s free.Our question at issue is In what way is fashion and interior design companies using marketing and Web 2.0 on Instagram and how does it reach individuals? To get an answer we contacted eight different companies and asked if they would like to answer some questions.

The purpose of this project is to analyze and study the absorption of the substances ivermectin, spinosad and barettin to hydrophobic and hydrophilic surfaces, and to analyze and study if the barnacle larva are effected when they try to settle on the treated surface.Incubation tests with barnacle larva in Petri dishes were performed as well as absorption tests on hydrophobic and hydrophilic surfaces which were tested with ellipsometry. To determine the surface thickness.The barnacles were placed in hydrophobic as well as hydrophilic Petri dishes that had been incubated with ivermectin, spinosad or barettin. After four to six days the larva was counted to analyze the settling. From the results conclusions could be drawn about the adsorption abilities of the substances to the different surfaces.The barnacles were placed in hydrophobic as well as hydrophilic Petri dishes that had been incubated with ivermectin, spinosad or barettin. After four to six days the larva was counted to analyze the settling.
