In Lake Vänern, Sweden, there is an endemic population of Atlantic salmon (Salmo salar L.) that lives its entire life in fresh water. The salmon is hindered from migrating to its natural spawning sites in the northern part of the River Klarälven by nine hydro-electric power plants. None of the hydro-electric power plants have fishways so that salmon migrating upstream or downstream may pass. In the current situation, the upward migrating salmon are caught in a fish trap at the most downstream located power plant in Forshaga. From there, the salmon are driven in a truck, past eight power plants and released a few kilometers upstream of the eighth power plant at Edsforsen.

Transmission of reactive power is well known to cause active power losses. Thus, newcomponents who can help minimizing these expensive reactive power flows are ofgreat interest to the power distribution companies. ABB Corporate Research hasdeveloped the first electronic power breaker. One possible application for thisbreaker is transient-free switching of capacitor banks. This could prove a usefuldistribution voltage complement to the switch-sync technique, mainly applied to transmissionvoltage level.

Aim: The purpose of this study is to explore how the media through a certain discourse constructs a view of the labor market and the power relations between companies, unions and employees. The goal is to explore this through studying the media coverage of SAS? financial situation between September-December 2012 and our research question is the following: What view of the labor market and its power relations was constructed and reproduced by Swedish newspapers through their portrayal of SAS during September-December 2012?Method: This study analyses the findings with the help of questions based on theories of social constructivism, discourse, agenda-setting and power. A content and discourse analysis was compiled of 360 articles from five Swedish newspapers that addressed SAS and their situation from September-December 2012. The results of these analyses were further processed using power analysis and John Gaventa?s power cube.Results: In this study we conclude that the medial discourse constructs identities of the different actors and affect power relations between them, in favor of the company.

The purpose of this study was to examine how social work professionals view their professional role and how they think about the concept of social work. I also wanted to investigate what they believe characterize a professional social work. For the purposes of this study, I chose a qualitative approach in which I interviewed five people linked to the social work. The theories which I have assumed in the analysis of the results are power theory, organization theory and professional theory. The results of this study show that the respondents believe that a professional social work is performed by someone who has training and experience in the field.

The aim of this thesis is to form a theory of the green consumer power and to distinguish whether this phenomenon could indicate a movement toward the ecological citizenship. To do so, scientific theories regarding the responsibility of companies have been used, as well as the public choice theory, to link individuals as citizens to individuals as consumers. The motives of corporate environmental responsibility, along with consumers ability to bring pressure in different dimensions, are later drawn on as indicators applied to empirical information. The largest producer of ecological products in Sweden, Arla Foods, is employed as case study to explore if the green consumer power can and does exist. The ecological citizenship uses the ecological footprint, to define in what ways we can minimize our part of environmental degradation.The study seems to strengthen the theory, consumers do have a power to make companies go green and they tend to use it increasingly.

The purpose of this study has been to investigate advantages and problems with distributionsystem metering in substations. This report is a study in cooperation with Göteborg Energi.The analyses in this report are made for GENAB, a subsidiary company of Göteborg Energi.To analyse advantages and problems in advance is interesting information for GENAB. Theresult of the report could be based upon whether installation of metering in distributionsubstations will be implemented and in that case which kind of measurement that is relevant.The most relevant and strategic place to implement measurement is at the distributionsubstations on the secondary side (400V), this is due to the placement of the currenttransformers. The measurements in this study involve current, voltage, power, power factor,temperature, energy and power quality.Measuring instruments that are relevant to implement are intended to measure current,voltage, power, power factor, energy and, possibly, power quality in the same measuring unit.It is desirable to have a measuring instrument that measures both energy and power qualitybut since it is most often a cost question, it can be established that energy meters have a lowercost.Metering in distribution substations gives a better illustration of the power network. Thisresults in many advantages for GENAB.

Academic research concerning how to determine the power situation in a supply chain where an investment product supplier is involved did not exist. Therefore new models has been developed that analyses the power relations and maps out the power situation in a supply chain. In the future these models can be applied on similar cases by modifying the included parameters. The new models show that case company FAS should focus on the big producers of garbage bag which are Trioplast, Rullpack and Miljösäck. By strengthen the brand FAS can make more money in these relations.

This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.

The idea with this study is to examine if there are a connection between how optimistic people are in relation to how stressed they feel. The result from the survey is based on materials from a questionnaire has been sent to fifty persons of varying age and sexes. The questionnaire has also been sent to students from Karlstad University but also to friends and acquaintances. The data is measured with SE- and LOT-tests. The issues concerned in which scope respondents experiences themselves stressed and optimistic and how the connection is between experienced stress and optimism in relation to results on the figure tests.

Wind power is one of the sources of renewable energy which has to be developed further in order to lessen our dependence on non renewable sources of energy. It's mainly oil and coal which have to be replaced by green energy. Wind power is already established in many countries, for example Germany, The United States of America and Denmark but it has to be continually developed and expanded to meet the needs of the growing energy consumption in the world. During the last few years many types of small wind turbines have appeared on the market. These small wind turbines are an alternative to the big wind turbines or power generators which demand huge sums of investment money.A new target group can now buy the small wind turbines in order to cover their own usage of electricity.

Länsförsäkringar in Värmland, Sweden, had during the year 2003 a total level of 6.1 percent of people on the sick-list, which was higher than average in the business (4,5%) and for salaried employees in the private sector (3,3%). The average age of those put on sick-list was 47 years, whish is four years higher than the average for the whole LF-group. The cost for the total amount of people being on sick-list at LF-company (6,1%) was estimated to 1 500 kkr, according to a calculation model coming from Försäkringskassan. For every percent the sick level could be reduced, the company would save 239 kkr. To map out the state of health of each and every collaborator in LF, the company offered all employees to make a health profile at the company's health service, Clarahälsan AB.

The purpose of this study is to find out the viability in performing final felling in stands with high timber volume or if it´s more profitable to leave these stands to the next owner. Will he or she pay more for the standing stock then the industry? The prices of forest-land have increased significantly over the last couple of years in Sweden and some properties seem to go higher than others. Is this because of higher standing stock volume or can a certain volume/hectare bring a higher price? Maybe a combination of both? This study is based on the the sale-statistics for 2012 from real-estate agency Areal.

 Detta är endast en del av ett stort arbete, på grund av omständigheterna (till exempel möjligheten att publicera en power point) har vi varit tvungna att begränsa vår publikation till lärarhandledningen. Det finns också en elevutgåva, power point-presentation samt ett prov som inte publiceras. För att ta del av dessa krävs möjlighet att komma åt Biologi C för lärares kurswebb Vt-2008 på Södertörns högskolas intranät. .

The purpose of this study is to investigate whether it is possible for SCA to update their stand register with use of digital aerial photos photographed with a Zeiss/Intergraph DMC. ?Updating? in this study implies the delineation of stands and estimating stand variables such as average stand height, volume density, stand volume, and tree species composition in order to identify stands which can be of current interest for thinning. The study also includes how the aerial photo material and experience of the interpreter can influence the quality of the interpreted variables. The aerial photo interpretations were made by both experienced and inexperienced interpreters.

Media has the power to influences society. Some call them the third power of a state. Through amongst others, the agenda setting theory and the framing theory, this report seeks to understand how media describes the swine influenza and how it uses its power to influence people to vaccinate. As this report will show, there is no doubt that media has had an impact on the Swedish population of which 60 per cent followed through with the vaccination. Media used an information discourse and attempted to present its articles in an impartial manner and used governmental authorities and experts to support its arguments.
