With growing economies and better living standards in many parts of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer.The company Minesto has developed a technology that is called Deep Green. It is designed to gain electricity from tidal currents. Deep Green works in a similar way as a kite that is attached to the seafloor with a moving wire. It contains of a wing that moves due to the water current.

The construction industry is currently receiving much criticism for inefficiency and slow development while demands for reduced built in moisture and efficiency increases. This report examines whether the use of field factories can meet these requirements and what factors that will be critical for future use of field factories. Industrialized construction with field factory is compared with traditional loose timber construction and industrial construction in the fields of execution, logistics and working environment. The aim of this report is to provide a basis for field factories current and future use and development. To achieve the aim of the report, people with experience in the use of the various methods was interviewed and literature studies in the various fields done.

The purpose of this thesis is to increase the understanding on how market leading pharmaceutical companies in Sweden limit the market share decrease when these companies patent expires. In order to respond to the purpose, two research questions have been asked: how do pharmaceutical companies deal with market strategies prior to the expiration of a patent: and how the market strategies is used when a patent has expired and as a consequence, generics entered the market. A case study was implemented based on two interviews with a brand manager and a therapy area manager within the company Pfizer AB in Sweden. The results suggest that pharmaceutical companies implement strategies in numerous ways which differs substantially from the theories, this having to do with Swedish legislation. The main aim with the execution of the strategy, before and after patent expiration is not to limit a decrease in market share hence, rather to retain the pharmaceutical companies strong brand image.

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Rapid urbanization causes competition over land use between green area preservation and urban development in cities and greatly affects ecosystems as well as human well-being. This conflict is significant all around the world as many cities are now replacing existing green areas with new developments. The area around Dag Hammarskjöld's väg in Uppsala is currently experiencing the same conflict, as the need that the city has for new housing represents a threat for the many valuable green areas that are in the site. The purpose of this project was to understand how the need of urban development and the preservation of green areas could be balanced. This understanding would thereafter be used to make a design proposal for the area around Dag Hammarskjöld's väg.

Title: What women want ? a study about young men?s self-presentation on the on-line dating site Spray Date.Authors: Anna Tuvehagen & Josefin HultTutor: Lena Widding-HedinPurpose: Our main purpose was to identify implicit norms and ideals for masculinity in young men?s advertisements on the on-line dating site Spray Date.Questions: How do the men present themselves on Spray Date and what do they accentuate in their advertisements? What kind of relationship do the men hope to establish and what qualities and attribute do they look for in women? Are there any notable differences and similarities regarding our findings of ideals and the ones in previous research?Method: In order to answer our questions we chose 100 advertisements made by men in the age 18 to 25. To analyse the advertisements we used a qualitative content analysis, however we have some quantitative elements.Main results: The men in our study are searching for love on Spray Date and usually describe themselves as nice, cheerful, decent guys with good sense of humour. Although, spare-time interests and activities are what the men mainly focus on. Their interests are broad and all sorts of combinations occur why it is difficult to place the men in categories.

WordPress är ett av världens mest populära Content Management System. Eftersom det har en hög popularitet drar det till sig uppmärksamhet från personer och grupper som av olika anledningar vill utnyttja säkerhetsbrister på webbsidor. Syftet med denna uppsats är att testa säkerheten i olika tillägg till WordPress som externa utvecklare skapat eftersom dessa inte genomgår någon obligatorisk säkerhetskontroll. Insamlingen av data skedde via ett utförande av statiska tester på några utvalda tillägg. Denna teknik grundar sig i en granskning och analys av dokument i form av text, modeller eller kod.

Extensive planting of the tree species lodgepole pine (Pinus contorta var. latifolia) during the 1970s and 80s has resulted in large areas now being available for commercial thinning. However, the varying quality of the stands creates a problem. The purpose of this study was to investigate, at the Torsby district of the Stora Enso forest company, how well the present computer records of the stands correspond to reality and determine which stands are, from a qualitative perspective, suited for timber production. Finding variables that indicate better stands would give Stora Enso the possibility of selecting qualitative stands which are more profitable to thin. The study included 32 stands containing at least 70 % Pinus contorta.

This survey was made during the summer of 2004 and the spring of 2005, on commission from the National Board of Forestry. The aim of this report was to investigate how often Norway spruce (Picea abies L. Karst), is planted on poor Scotch pine (Pinus Silvestries) sites and if it affects the yield of Norway spruce? In order to investigate this, data from 29 stands witch had a lower site index than T24 was collected. The investigated stands were situated in the southern-eastern Sweden. In 20 plots in each stand, the highest tree, age, number of seedlings, site index and tree species per stand were measured.

The purpose of this paper was to gain knowledge about the conversation about developmental opportunities in the organization, and how a company uses it. The focus was on four different themes, purpose of the conversation about developmental opportunities in the organization, planning, execution and content, feedback. The sample consisted of six people, three employees and three managers of the company. The interviews were conducted by an interview guide, one for the employees and one for the managers. The results of the interviews showed that the conversation about developmental opportunities in the organization was used by managers to make all employees to strive in the same direction, an opportunity for employees to reconcile how their work performance is perceived by their managers, the use of a preparation model differs between managers and feedback was important.

This master thesis encompasses an inventory of the older industrial community of Gimo. Investigations of the contamination situation for each industrial area were done. A risk classification according to the Swedish Environmental Protection Agency?s ?Method of Surveying Contaminated Sites?, phase one, followed. The risk classification was done on areas of Iron Work, a rockwool industry and a landfill. Gimo have had iron manufacturing from 1615 until 1945. Gimo have had two blast-furnaces and two smithies periodically.

Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety. One of the regulation systems includes the short chain fatty acids produced during feed degradation in the rumen. Starch can be digested either in the rumen where short chain fatty acids are produced or in the small intestine where glucose is the end product. Since glucose does not have the same effect on satiety that short chain fatty acids have, the site of starch digestion might be an important factor that affects feed intake and milk production. The aim of this study was to investigate the effects of site of starch digestion on feeding behaviour (feed intake, consumption time, and eating frequency) and milk production. Because feeding behaviour is closely connected to the cows? environment, the study also included observations of behaviour. Three different feed rations were compared.

REFERATÖvergödning är ett högst reellt hot mot många av Sveriges sjöar och vattendrag och inte minst mot Östersjön. Utsläpp av ej tillräckligt renat avloppsvatten och läckage av näringsämnen från jordbruksmarker är problem som länderna kring Östersjön måste lösa. Sverige arbetar både nationellt och internationellt med att förbättra Östersjöns ekologiska status. Riksdagen har satt upp flera miljökvalitetsmål som bland annat tydliggör att Sverige måste minska tillförseln av näringsämnen till sjöar och vattendrag. Orsaken är att dessa föroreningar är en bidragande orsak till övergödning.
