Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.

The increasing road traffic in Sweden will require investments in the infrastructure that the tax withdrawal of today will not allow according to a new government report, SOU 2006:33. An existing willingness to pay for those investments has therefore become an alternative to increases in taxation to be able to cover the costs. A proposal to let the willingness to pay, alternatively increases in taxation that act proportional, decide how a cost is distributed can be said to be related, but not fully correspond, with different theories of justice described by Robert Nozick and John Rawls. It can therefore be interesting to see how the two different theories of justice are edified and how they distribute a joint cost. The aim of the first part of the thesis is to present and criticize Rawls' and Nozick's theories of justice in a common formulated economic model.

In Sweden there has been a surge of interest in the films classified as pilsnerfilms, i.e. comicalfilms produced for little money in the 1930's and containing a more working class and/or ruralsetting then the so called "champagne comedies" from the same era. The concept"pilsnerfilm" is how ever a little vague and although the main focus of this paper ispilsnerfilms, it will also cover other types of comical films made in Sweden between the1930's and 1940's.This paper examines the now-existing network of people interested in these types of movies.It will do so by interviewing seven of the most prominent fans of movies made during the1930's and 1940's. Most of them are living in Stockholm. The paper discuss how through theconsumption of these types of films, a nostalgic gaze is created.

Mot bakgrund av att medier kan definieras som en socialiseringsfaktor samt att sexualitet är ett ämne som ofta vädras i olika medier är syftet med den här kvalitativa studien att undersöka hur livsstilsmagasin, i sina texter, skildrar sexualitet och då närmare bestämt kvinnors sexualitet. Kvinnors sexualitet undersöks av den anledningen att kvinnor under 1800-talet drabbades av en avsexualisering, det vill säga deras sexualitet förminskades i förhållande till männens, vilket sannolikt påverkar samhället än idag.                      Studien har tre frågeställningar där den första rör huruvida denna avsexualisering präglar livsstilsmagasin. Den andra frågeställningen undersöker vilka ord som används i livsstilsmagasinen för att beskriva det kvinnliga könsorganet. Den tredje frågeställningen har fokus på hur stor del av innehållet i livsstilsmagasinen som präglas av sexualitet, på ett direkt eller indirekt sätt.Ur ett medie- och kommunikationsvetenskapligt perspektiv lutar sig studien mot ett teoretiskt ramverk kring mediers påverkan, då främst hur unga människor påverkas, samt agenda setting. Jenny Kitzingers forskning har en central roll.

This study includes several purposes which are to describe the concept of working environment, explain who is responsible for its functioning and how the working environment should look like. Other purposes the study have is to investigate how the working environment is in both Swedish and the two investigated companies construction sites and to share some operators proposing measures for the shortcomings and problems that exist in the construction sector working environment. To achieve these purposes was a qualitative study made with unstructured observations, interviews and survey where three construction sites were observed. The result shows that the concept of the working environment cover many aspects and is essentially about the environment we live in and experience in our work and this environment can be both an indoor as an outdoor environment. In this work, the concept is divided into four areas; it is the physical, the ergonomic, the psychosocial and the chemical.

Horse keeping is gaining an increasing interest in Sweden. During 2004 to 2010 the number of horses increased with 10 - 20 %, and was estimated to be 362 700 in 2010. Julmyra Horse Center (JHC), situated in Heby municipality, is a gated community for people sharing a large interest for horses and a vision of a sustainable horse management has been formulated. This study evaluates how the horse keeping of today at JHC, and how an expansion of the horse keeping may affect the risk of enhanced phosphorus load to the nearby lake system Vansjön ? Nordsjön.

This is a study on winter groups, ?siida?, of semi-domesticated mountain-migrating reindeers that move to lichen pastures in the lowland boreal forests during winter. The aim of the study was to determine reindeer habitat use in their winter ranges in a managed forest landscape. The reindeers use of three different types of forests was determined, 1) 100-130 year old, 2) 20-40 year old forest and 3) clear-cut areas. All sites were dominated by Scots pine, Pinus sylvestris, and had the same types of ground vegetation.

The intention of this thesis is, from a basic statistical viewpoint, to capture the relationship between the price of electricity and a sample of factors influencing the price. The thesis also aims at investigating whether knowledge about the relationship is useful when investing on Nord Pool. Tested factors are temperature, import, price of emission rights as well as a number of hydrological factors. The investigated period stretches from year 2000 until week 32 year 2007. The relevance of each factor was also evaluated yearly as well as for shorter periods in order to get a more comprehensive view of the relationship.

The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.

In the new Library Act of 2014, it is stated that public library supply should be characterized by quality. To investigate what this means for the library, I do a functional analysis of ideas of librarians' views on quality and how they work with purchasing, weeding and mediation. I have chosen to limit the essay to fiction for adults in Swedish public libraries. By combining the basal idea analysis, where I investigate librarians' ideas about quality, with an operational analysis of ideas, where I examine the effects librarians' quality ideas get for the daily work, Iwant to find out the librarians' quality ideals.The material I analyze consists of 18 questionnaires, filled out by librarians with responsibility for purchasing and / or thinning in libraries across Sweden. The analysis is done with an analytical schedule, that consists of a number of opposing ideal types taken from previous research on quality, purchasing, thinning or mediation.

Abstract New methods, techniques and tools for the building industry are constantly being developed and improved and launched on the market. The problem in the building industry development is not that the products are not good enough. The problem is instead that the existing construction companies do not choose to use these innovations, instead they continue to employ the technologies they already possess and master. This leads to the fact that the construction industry is, in the public eye, beeing seen as a conservative industry. AquaVilla is a company that basically produces houseboats.

The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.

Flexible working conditions is used extensively in organizations today as a way tocreate flexibility for the employer. Recently we?ve been reading in the newspapersthat this approach is a growing problem and the EU has warned Sweden twice thatabuse of these forms of employment must be stopped. The Government has recentlysubmitted a proposed rule change to reduce the possibility of stacking one temporarycontract after another. Borlänge kommun makes themselves more flexible with theintermittent employments.

The demand for renewable energy is increasing in Sweden. This consequently increases the pressure for and willingness to pay for forest fuels. One method to extract forest fuel from suitable commercial thinnings is the "long top method? (LT-method). With this method saw logs and non-delimbed tops are recovered, i.e.
