This paper goes through solar energy and what uses it has. It is also a guide in the choice of solar collectors forthe real estate that I have drawn for the thesis work.Solar energy is a renewable source of energy from the Sun's light. Energy can be used to produce both heat andelectricity through solar collectors and solar cells. Some of the benefits of solar energy is that it is completely freeto extract, environmentally friendly and virtually maintenance-free. Disadvantages are that the technology isexpensive, does not cover the entire energy needs and takes a long time until it pays.

SUMMARYEnvironmental issues are currently a hot topic of debate. Studies within the optics branch have not specifically been conducted previously, so the aim of this study was to determine the extent of environmental-awareness specifically within this branch.A survey, consisting of questions relating to environmental issues, was distributed to 100 randomly-selected opticians in Sweden. Of these 100 surveys, 64 were returned and showed a varied branch-engagement for environmental issues.Results of this survey showed that opticians were best in sorting newspapers, magazines, other paper and hazardous waste. Metal and rigid plastic were not sorted to any larger extent.Choosing environmentally-safe products was not so popular and only six stores always do this. 25 shops turn off electrical machines and equipment over night; while the majority of the remaining stores leave the machines on during the night.27 stores did not know if their electrical company provided ?green electricity?.Results showed that there is a lot of work to be done in making the stores more environmentally friendly.

In modern society in terms of economics and environmental impact, it is important to ensure that a company is as energy efficient as possible to reduce the amount of energy used. About 10 TWh of electricity used annually to pump drives in Swedish industry. Therefore, pumping system has great potential for energy savings.The objective of this report was to determine how much energy and money that can be saved with the insertion of variable speed drive to six pumps on Bleach plant 4 in Skutskär Mill. The work was performed with electrical measurements during one week, analysis of pump curves and the compilation of production data over a year.The results show that four of these six pumps were profitable and yielded an annual saving of 1172 MWh of electricity and 560 000 SEK. With an economic lifetime of 10 years and a discount rate of 6.8% the final result for the entire life-cycle savings became 3 355 000 SEK.

Visby is a city that at first glance is of medieval origins. The popular image of scientists today is that the city was formed in the Middle Ages. According to some of the researchers Visby was formed during the Viking Age, it is based on the basis that the area has been used for a long period. Urban development in the Nordic countries is complex and there are different opinions as to why the Nordic cities emerge. It is important to shed light on the underlying process on why cities are emerging to provide clarity as to why Visby city is emerging.

The purpose of this thesis is to investigate if the stock market reacts differently to accounting information, depending on the stock market climate. The study focuses solely on stocks listed on the OMX Stockholm 30 during each year from 2005 to 2009. By applying the concept of Earnings Response Coefficient we can estimate how the market reacts to accounting information. The dependent variable in the equation is the market reaction on unexpected earnings, in the study described as the abnormal return on stock. For quality purposes we measure this on a ±1,5,10 and 20 days basis.

This paper aims to investigate abnormal returns for rivals to bidder targets in connection with the announcement of the bid. The study is based on 38 bids placed between September 2006 - January 2011 and 137 rival firms listed on Nasdaq OMX Nordic. We measure cumulative abnormal returns, CAR, for rival firms through an event study. We find that rival firms earn significant positive CAR in connection with the announcement of the bid. This is in line with the two-sided signaling effect presented by Akhigbe et al.

The Swedish pharmacy market will be re-regulated in July 2009 which will present private actors with an opportunity to enter the market. Several risks and uncertainties are associated with such an entry. The purpose of this thesis is to increase the understanding of identification and management of risks and uncertainties associated with entering the Swedish pharmacy market. We also intend to investigate similarities and differences in risk identification and risk management as well as create an understanding of the underlying reasons for these similarities and differences. Three companies interested in entering the market have been interviewed and the interviews were conducted with an open approach to avoid influencing the companies? answers.

In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.

Method: The thesis is based on literary studies. By combining theories and empirics regarding the health care market, competition and profit, a deeper understanding of the aspects important for the chosen subject, is created. Combined with official reports and the new legislation, an analysis is formed.

Angelica archangelica (Garden angelica) is the only Medicinal and Aromatic Plant (MAP) with a Nordic origin. The plant can reach up to three meters when cultivated. Angelica archangelica is used as flavouring in additives, honey, beverage base, essential oils, fol-klore medicine and as ornamental for decorative purposes. Commercial cultivation is mainly focused on root production. Production countries are Poland, Netherland, France, Belgium, Switzerland, and former Czechoslovakia with an overall yearly world production of 1000 kg of essential oils.

Sexual function in men with Spinal Cord Injury (SCI) is usually affected to a greater or lesser extent, depending on the type of injury and physiological prerequisites. Social contexts and psychological factors are other aspects that affect sexual function. Sexual dysfunction can lead to an impaired quality of life, depression and other illnesses. Aim: To study reported experiences of sexual function in men with SCI who have participated in The Nordic Spinal Injury Registry (NSCIR) five years follow-up. Design: Quantitative method consisting of a register study based on secondary data.

The share of problem gamblers increased for men between 18-24 years old during the period 1999-2009, while the share were steady or decreased for other classes of population. This study examines the relation between this development of problem gambling and the Swedish gambling market. The factors that are studied are the functioning of the market with a focus on the new Internet market for gambling, the games and the underlying risk factors in those, the marketing and other factors outside the gambling market. First a large literature review was made to map the development as detailed as possible. After that a qualitative analysis of the content in television commercials was done to see if they were made for the problem group.

Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase their treatment capacity at their biogas plant. In connection to this work it is also possible to make some energy saving changes to the biogas plant. The objective of this study was therefore to make an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the sanitation step and also a comparison of energy consumption with the present sanitation method and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method is heating to 70 °C during 1 hour). The energy survey was conducted in close collaboration with staff at the biogas plant. The current during normal operation was measured, power was calculated and multiplied by the time of usage to obtain the energy consumed.

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.

Återköp utgör en stigande andel av företags utdelningspolitik. Enligt von Eije och Megginson (2008) är market-to-book ett nyckeltal som influerar utdelningspolitiken. Denna studie undersöker hur market-to-book påverkar valet mellan utdelning och återköp. Signalhypotesen används för att förklara hur market-to-book kan sända signaler om under- eller övervärdering av företag och på så vis förklara detta val. Studiens resultat visar att det inte finns något samband mellan market-to-book och hur företag resonerar kring sin utdelningspolitik.
