Pellets - en framtidsmarknad?
With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods.
The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute.
2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.
Småskalig biobränsleeldad kraftvärmeproduktion : teknik och investeringsutrymme
To achieve the requirements to decrease emissions of greenhouse gases by 20 % by 2020, Swedenneeds to increase its use of bioenergy. In doing so it seems natural that those who already haveaccess to large amounts of biofuels in the form of by-products such as straw, wood chips anddigestible materials take advantage of these assets locally. By combining production of heat withpower production at the farm it may be possible to not only reduce the direct use of fossil fuel forheating but also reduce energy costs.The purpose was to simulate different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and from this the possible electric output iscalculated. This study has focused on the impact of the following properties: electric-, heat- andtotal efficiency, fuel, fuel price and specific fuel requirements.
Aktivisten- egoist, karriärist eller eldsjäl? En studie rörande motiven bakom frivilligt engagemang
When it comes to investigating the motives behind activism, the members of political study have a lot to say. I aimed to critiqually rewiev this in my thesis. I asked the question ?What do the actor themselves claim lay behin their decision to become motivated?? To highlight this complex dilemma, I sought to discuss new social movement theory by comparing it to reality. This includes a literate examination on contemporary political science approaches, and a study of two organisations in the south of Sweden, choosen not to despise any excisting theory, but to give it a sense of reality.
Optimalt råvarulager för biobränsleföretaget :
This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant.
Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.

En bild säger mer än klara ord : En undersökning av visuella och narrativa komponenter i myndighetstext
According to law all Swedish authorities must express themselves using correct, plain and comprehensible language whenever they communicate with the citizens in order to make it easy to understand what needs to be known to participate in the Swedish democratic society. I would like to explore if there are more tools than the language that could be used to make their communication easier to comprehend, in this case images and stories. In this essay I will investigate the relationship between the written words and the visual components ? images and illustrations ? in brochures from Swedish authorities. I will also try to identify possible narratives in the brochures, and examine the functions of these narratives.
Förändringar och Förvillelser : Skriftspråkets modernisering mellan år 1895 och 1938 i en roman av Hjalmar Söderberg
This essay ? Discourse and Dissonance ? deals with Mary Shelley?s gothic novel Frankenstein; or, the Modern Prometheus (1818). The focal point is the construction of ?Them and Us?, as defined by scholars such as Stuart Hall, viewed in terms of the following categories: race, gender and family, class, and sexuality. Rather than applying an outside perspective, e.g.
Uthållig Demokrati med exkludering? En analys av diskursen om strukturell politisk exkludering i Demokratiutredningens slutbetänkande
The purpose of this study is to analyse the discourse on political exclusion in the official report Demokratiutredningen. It has been my ambition to relate the analysis of the report to a critical academic discourse on political exclusion and thereby make visible hidden norms and structures which functions to exclude certain individuals and groups from political participation.My paper point out that the report establishes a strong link between democracy and participation and that it, therefore, makes a strong case for a process of democratic inclusion. Though, in my study I suggest that that there is an unawareness of the importance of norms, hegemonic conceptions and structures and that inclusion, therefore, is unlikely to take place. Furthermore, I criticize the focus on deliberative democracy in the report. With insights offered by Mouffe in her argumentation on the necessity to acknowledge the dimension of antagonism present in all societies I underline that the focus on this democratic model is problematic.My conclusion is that the analysis presented in the report is insufficient if we want to create a democratic system characterized by equality..
LIP : en effektivitetsstudie
Lokala investeringsprogram was a subsidy program which supported environmental reforms during the years 1998 to 2002. The subsidies were given to Swedish municipalities. Most of the evaluations of the subsidised projects have now been completed and included in a database.
The purpose with this thesis is to analyse whether the instrument has been effective with respect to carbon dioxide reductions and costs. These calculations have focused on subsidy and cost efficiency. The analysis has been compared with a previous report called "LIP ur ett samhällsekonomiskt perspektiv".
The result shows that the reduction cost for one kg CO2 has been almost one SEK, which is twice as high as the cost reported in a previous report, half a SEK.
Transnationell kooperation : en studie av DLA Agro
Farmers Cooperative has in recent years developed from national markets to cross-border, international, collaborations. One example is the merger between the Swedish dairy company Arla and Danish MD Foods, where the companies collectively are sought to reduce transaction costs and thus improve efficiency. The Swedish market for commodities (fertilizers and pesticides) in agriculture has for many years been dominated by a few large players, with little opportunity for grain associations and local grain companies to offer their customers a varied range of commodities with a competitive pricing.To change this state, a majority of Swedish and Danish grain associations and local grain companies have established a trans-national cooperation. Through the establishment of the organization DLA Agro, they offer their customers a good variety of products with competitive prices. This study investigates thus according to the theory of cooperative models to what extent and how the DLA Agro helps to create benefits for the Swedish member companies.
Kvalitetsarbetet i Nacka : En fallstudie av kundvalsmodellen inom äldreomsorgen
This essay discusses the interaction between the authorities in Nacka municipality in Sweden and supervisors within the eldercare. In Nacka politicians have gradually started delegate responsibility for how care-giving for the elder should be done and focus instead on formulating economical objectives and overall rules. It is up to the approved supervisors of eldercare to deliver good care and quality. The method chosen to accomplish this is public choice. This method is a part of the big New Public Management (NPM) reform which have had a big impact on Swedish public sector since the 1980´s.
Leverantörsrelationers betydelse : en fallstudie på Scania och två av dess underleverantörer
One of the most distinguishing features for companies today is that they must have a close collaboration and keep up a good relationship with their suppliers. This is important for the companies chance of survival and for them to compete in their markets. This essay will discuss the subject of Scania?s long-term collaboration with their suppliers. The purpose of the essay in this case study is to analyze if a long-term cooperation with a supplier is of essence upon renegotiations of continued collaboration.
Den kulturpolitiska forskningens intellektuella bas och inriktningar ? En författarcociteringsanalys av artiklar publicerade i International Journal of Cultural Policy 2002-2007
The aim of this thesis is to map the intellectual base, and identify the general research interests, of Cultural Policy studies. In addition to this the thesis also aims to trace the uses of theoretical and conceptual approaches within the identified research interests. This is done by analysing citations from 130 articles published in the leading scientific journal International Journal of Cultural Policy between the years 2002-2007 using the bibliometric method author cocitation analysis (ACA). The results of the ACA confirm the overall notion that the research field of cultural policy studies is an ambiguous one, even when it?s studied with a quantitative method specialised in uncovering hidden structures within a given field as ACA.
Evaluation of specificity of a walnut antiserum and detection of English walnut (Juglans regia) in food with ELISA and Real-Time PCR
Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.
Problemet med Sverigedemokraterna : En studie i hur Sverigedemokraterna representeras i två svenska tidningar
The aim of this study was to examine how the political party Sweden Democrats is represented in two Swedish newspapers. The study included a national newspaper and a local newspaper, Aftonbladet and Blekinge Läns Tidning. We studied 35 articles from both papers, from 2005 and from 2009. We analyzed the texts using the linguist Norman Faircloughs (1995) method for discourse analysis. Based on his theories, we created our own model to examine the texts. Our model primarily focused on representation. The study was conducted at a time when Sweden Democrats was given much support in opinion polls and knocked on the door to the Swedish Parliament. The study showed that Sweden Democrats in both newspapers, primarily by descriptions, the choice of interviewees, etc., often are represented as racists.
