Recent turmoil surrounding nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant.

The purpose with the work is to study Fortums activities with hydro power plants, dams and reservoirs mainly in a premise jurisdictional perspective and to show how GIS would be a helpful tool for the future.A great deal of the information that the Generation Hydro-division at Fortum are managing have a spatial element. That means that it is possible to spatially join this information to a geographical polygon, line or point. This information is today gathered from several different sources, such as files, paper maps and digital data of several kinds. A Geographic Information System (GIS), as and aid besides the ordinary tools should be an effective support in the everyday work with questions of a premise jurisdictional nature.The goal of this work is to account for how to organize, present and analyse geographic information. We will show how to link from the map to traditional tools such as calculation- and register programs.

The attitudes towards nature conservation in forestry are based on the individual forest owner. The theme of the interviews is the opinion on nature conservation in forestry. The purpose of this study is to identify if there is any difference in attitude to nature conservation in forestry according to the age of the forest owner. The study discusses different factors that affect the private forest owners consideration of nature conservation and give an insight in different generations attitude to nature conservation. Other topics that are discussed is if future change of generation will change the consideration of nature conservation in Swedish forestry and what is needed to enhance the interest in nature conservation among forest owners.This study is the result of interviews with a number of forest owners in the county of Uppsala, Sweden.

With the increased volume of commercial content online, some news sites have adopted so-called native advertising on their websites to convey marketing messages more discreetly. As an increased share of advertising budgets is spent on this form of advertising this essay aims to examine its news consumer?s attitudes towards the phenomenon. The research was carried out through a qualitative study where news consumers discussed their attitudes in two separate focus groups. This was analyzed with the help of the previous studies Advertisement - an uninvited guest? and Banner Blindness as well as theories including theory of science hermeneutics, reception analysis, convergence culture, brand schema, advertising schema and ad- brand attitude.The results show that in most cases native advertising is met with indifferent attitudes but in some cases also confusion, which could lead to negative attitudes towards the ad and the news site.

The climate affects animal populations through several processes. These processes includereproduction, phenology and the success of hunting. By influencing the phenology of species theclimate also affects the way species interact. If a climate-induced phenology change promotes abasal species to bud earlier in the spring for example, this will affect the links to other species inthe food web due to a time lag in the tropic levels above. This dependence, that a predator has tobeing synchronous to its prey, is called the match/mismatch hypothesis (MMH).

The purpose of this study is to conduce to the understanding of what challenges the HRdepartmentfaces in the work with the psychosocial work environment in nonprofit organizationsin Sweden. A particular focus in the study is on how the certain features of the nonprofit sectoraffect and tend to contribute to these challenges. In both Swedish and International research thereappears to be a lack of studies that deal with the psychosocial work environment in the nonprofitsector, which is one of the main reasons for this study. International research show, among otherthings, that employees in this sector have a higher degree of work satisfaction than in othersectors. Especially, they value the sense of making a contribution to the society, to get feedbackon their work performance as well as they expect a high level of co-determination.

Today we live in a more or less globalized society where borders do not pose the same obstacle as before. This is why it is interesting to examine whether different countries have similar views on how to communicate with a specific audiencePurpose: The purpose of this thesis is to use the data gathered to inform businesses with information. The information can then be used to assist companies when it comes to advertising, the design of messages and the choice of media channels when communicating with people born during the 80?s. Furthermore, the investigation intends to find out if there really is a global market for people born during the 80?s.Method: The authors believe that a purely quantitative or qualitative approach is not appropriate.

This study is based on a proposition about the legislation regarding sexual offences prepared by a commission initiated by the Swedish government in 1972 which was presented in 1976. The purpose of this study has been to ascertain the commissions views on rape based on their representation of the problem, their presuppositions and assumptions regarding it and future consequences in behavior for victims and offenders of the crime. The key results of this study is that the commission regarded the ?problem? of the then current legislation to be non-consistently with the time being. In their opinion the legislation needed to be loosened from its moral strings and be adjusted to the ?new? sexually liberal era.

As we all know Sweden as a country, appears to be homogenus. At the middle of 1960?s the emigrants from ancient Jugslavia came to Sweden as an workforce. At that time it was the majority of the emigrants from ancient Jugoslavia that established their lifes in Sweden. The second period for the emigrants from ancient Jugolsavia was at the biginning of 1990?s because of the civil war in Bosnia and Herzegovina.

The purpose of this master?s thesis is to find out in which ways a group of first generation immigrants use Swedish papers and magazines in a public library and which information needs this group has about Swedish society. One important aspect in this essay is integration of immigrants in the Swedish society as a possible effect of newspaper reading. The method used in this study is qualitative. Data is generated through semi-structured interviews.

AimThe main aim of this study was to find out how teachers reflect on their work with developing pupils? interest towards mathematics in grade nine. As a teacher in mathematics, it is important to be aware of different views on interest towards mathematics and how it is possible to work in that direction.

During the migration season in 2013 a study on spawning migrating salmon and the effect of water flow on the behavior was conducted of the salmon at the Forshaga hydropower station in the River Klarälven. The River Klarälven with its nine hydropower plants on the Swedish side, constituting migration obstacles for the migrating salmon. Fortum Generation AB has together with the County Administrative Board restored a salmon trap at the lowermost hydropower station in Forshaga, aiming at making it possible for the salmon to swim into the trap, and thereafter be transported by truck past the power plants and then continue their journey to the spawning grounds on their own. Unfortunately, it is believed that the trap does not work as well as it should. In this study, I focused on salmon position in relation to water flow and if the number of salmon that swam into the fish trap differed between salmon with previous experience of the trap (experienced) and salmon without experience (unexperienced).

The energy in laundry rooms, in form heated air, can be utilized with a heat exchanger. A concept and an early prototype of the heat exchanger have already been developed to show that the theory works. This report describes the continued development and construction of the product.A field study was made in order to investigate the environmental usage and establish the product design. The most common washing machine was used as a calculation model, and calculations were also made to estimate the amount of energy in the air. A previous analysis of the existing prototype is also presented in this report, to show the products potential capacity.

Äldreomsorg är i snar framtid i stort behov av mer arbetskraft och enligt SCB redan 2032 kommer det råda stor arbetsbrist inom området. För att kunna behålla den arbetskraften som redan arbetar inom området äldreomsorg bör vi ta reda på mer om deras tankar om ledarskap, motivation och om upplevelsen av arbetsglädje och vilka preferenser och vilka faktorer det beror på. Syftet med denna studie är att öka kunskapen om vilka förväntningar några av den yngre generationen medarbetare har på ledare samt vad som motiverar dem till att arbeta inom äldreomsorgen. Till denna studie valdes den kvalitativa metoden med semistrukturerade intervjuer. Fem respondenter födda mellan 1978 fram till 1995 deltog i studien.

The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.
