Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.

The aim with this paper is to investigate how the Social Democratic Party (SAP) deals with the question of economic migrants, or more specifically how the problem is represented by the Social Democratic Party, and how this representation has developed over time. The SAP's theory became recently contested by a competing theory that was caused by the predicted future demographic development in Sweden, combined with the EU's eastern expansion. The first factor contributed to the re-write of the theory, to a theory that saw economic migrants as a solution instead of a problem, in direct contrast to SAP's theory. The second factor was a direct threat to SAP's labour immigration policy. This leads to my second question, how did SAP respond to this pressure?The answers to these questions are achieved by using discourse analysis by applying a problem oriented theory on empirical material, constituting propositions, articles in mass media and parliamentary debates.

This degree thesis is based on an assignment from BEOMAT in Storfors. BEOMAT is a company that constructs and sellsclay pigeons to both the national and international market.Our main purpose with this paper is to find a solution/system that can replace the expensive and space demandingOlympic trap facility. Our solution will replace fifteen clay pigeon throwers with one automatic thrower whosimulate all throwers together. The system will be provided with an appropriate control system for mass productiontherefore this system needs to be user-friendly so no previous knowledge is required.Totally 405 different throw coordinates will be stored in the programme in nine different subprograms. According tothe Olympic-rules the throwers should coincidence within certain specified conditions, this will be solved with anrandomizer in the programme.

Through participant observation in a local promoter group of hardcore punk shows inGothenburg and qualitative interviews with its members I have investigated links between taste in music, values and social structures in the hardcore punk scene. The theoretical framework of this essay is built upon the concept of subcultural capital, which is adapted from Pierre Bourdieu and developed by Sarah Thornton and Keith Kahn-Harris. The result shows how members among the hardcore punk scene create and preserve distinction towards others, while the distinction becomes important benchmarks for including and excluding practices in the scene..

Andelen konkurrensutsatt offentlig verksamhet har ökat i jämn takt sedan början av 1990-talet, och utvecklingen har både sina förespråkare och kritiker. När det gäller de stora partierna inom de olika politiska blocken, är konsensus numera att konkurrensutsättning är här för att stanna, skiljelinjen ligger mer på hur stor andel av den offentliga verksamheten som skall konkurrensutsättas. Även bristen på en genomlysning och uppföljning av konkurrensutsatta verksamheter har väckt kritik. Kostnadseffektivitet är det som förespråkas vid konkurrensutsättning och används som syfte till att anlita privata eller korporativa aktörer etc., för att bedriva en tidigare offentlig verksamhet på ett mer företagsekonomiskt effektivt sätt.Syftet med uppsatsen var att undersöka hur Region Gotland använder sig av konkurrensutsättning och upphandling för att nå en företagsekonomisk effektivitet i sin verksamhet, och jämföra det empiriska underlaget mot tillgängliga teoretiska källor. För uppsatsen har följande två frågeställningar valts som uppsatsens problemformulering: (1) På vilket sätt genomförs konkurrensutsättning för att uppnå företagsekonomisk effektivitet i offentlig verksamhet? (2) I vilken omfattning sker uppföljning av verksamheter för att kontrollera att tilldelade resurser används på bästa sätt?Uppsatsen visade inte på något otvetydigt klargörande när det gäller ekonomisk vinst vid konkurrensutsättning, eftersom uppföljning och utvärdering av upphandlade verksamheter inte sker i den utsträckning som vore önskvärd.

This essay examines how three big Swedish newspapers depicts e-sports and computer gaming and how the depiction change during 2000-2013. The study will also examine whether e-sports is being portrayed as competitive sport. The purpose is to investigate which attitudes that can be identified towards computer gaming and its culture in major newspapers such as Aftonbladet, Dagens Nyheter and Svenska Dagbladet and how these attitudes eventually changed over time. The sources that will be used in both the quantitative and qualitative analysis are based on web articles, mainly because the paper editions does not provide much, if any, information about computer gaming and e-sports and also because of the convenience of being able to quickly find articles to study. Results indicate that computer gaming is being depicted in a clear negative fashion during 2000-2006, and that the depiction of e-sports is somewhat positive but not as glorifying as for the years 2007-2013. During this period, there is a apparent tendency of e-sports being introduced to readers who are unfamiliar with the gaming culture. As for the attitudes towards computer gaming, the depiction is still somewhat negative, mainly because the debate about computer games and violence was revived because of several acts of violence in shape of school massacres and mass murder.

I am in this essay to find out how to successfully combine new development with preservation of natural values, mainly large scale vegetation and ground formations.This is done by studies of three developments. The first development, Engeltofta backe, lies 7 km northeast of Gävle. The expectations of natural preservation were not fullfilled when this area, after the explotation, did not have any vegetation of value left. The second example, Östra Kvarnskogen in the community of Sollentuna, shows, as far as one can tell at the moment, a sucsessful combination of new development and preserved nature. The third example is a development in the community of Kullön. In this area the ambition of combining preservation and development was fullfilled. After studying vital documentation in each planning process, I made interviews with different actors in each of the three processes. I thereafter compared the different documents and answers from the interviewed persons to find out if there were any significant similarities or differences which could be of importence when natural values is to be preserved in new developments. My conclusion of this study is that it is of great importence to define key expressions often used in the process, such as natural values and preservation.

Farmers are required to make sure that cattles basic needs are met, but still every year cases of neglect occur where the farmer has not complied within the animal welfare law and regulations. The aim of this study was to investigate how cattle are affected physically and behaviourally by neglect in the form of underfeeding, starvation and lack of sanitation, which animals are most vulnerable to the impact and what prospects they have to recover. The study was conducted as a literature study and the results show that these types of neglect have a large impact on the cattle welfare. Underfeeding and starvation causes physical changes leading to reduced milk production, reduced muscle mass, impaired immune function, poor reproductive performance and changes in rumen microflora leading to decreased number of microbes and pH change. Physical changes due to the lack of sanitation consist of increased vulnerability to hoof diseases and mastitis, burns, and increased sensitivity to temperature.

The Swedish State Road Administration has since 1992 procured operations and maintenance of state roads on the open market. The procurement has been termed ?Grundpaket Drift?, GPD, and comprises mostly operational measures for road networks.The clients of GPD, SRA regions, have gradually changed the original documentation in order to adapt it to local conditions. This process has gradually led to that some parts of the documentation are creating problems for contractors interested in procuring jobs.This thesis tries to analyze GPD and clarify the differences that may be essential to the procurement process and to facilitate future joint working projects and processing descriptions..

The discussion about gender and ideals shown in mass media is a subject of great importance for the society in general. Media is playing an essential part when it comes to establish standards and values and we are constantly exposed to all types of impressions, whether we are aware or not. It is therefore of great importance that we understand how stereotypes are built and to gain a deep knowledge that would enrich the area of Media and Communication Studies.The aim and focus of this study was to analyze how male stereotypes is communicated in print advertising and how visual means of expressions helps to construct the masculinities shown. From a semiotic analysis of seven print adverts appearing in the Swedish lifestyle Magazine Café were we able to gain a thorough understanding about how male stereotypes are communicated and built.The result showed that different kinds of stereotypes are in fact used but it is still a hegemonic masculinity that is predominating. Traditional male characteristics are still in use but we were able to see strong indications of effemination, sexualizing and objectifying.

Arbetet har sin utgångspunkt i en beskrivning och analys av den befintliga situationen. Med hjälp av den historiska bakgrunden har analysen fördjupats. Arbetsområdets avgränsning har gjorts med hänsyn till infarternas sträckning och utformning. Förslagsarbetet har varit inriktat på att ge de tre infarterna en egen identitet samtidigt som det ska finnas ett gemensamt tema som är specifikt för Ronneby. Utformningen av förslagen ska förstärka vissa attraktiva faktorer medan annat som inte är lika attraktivt tonas ner. Arbetet är ett idéförslag hur Ronneby som stad skulle kunna göras attraktivare genom vackra, värdiga och funktionella infarter..

Det övergripande syftet med detta arbete var att skapa en övergripande sammanställning rörande ämnena flödesproblem och silodesign och specifikt ta fram riktlinjer för hur massflöde ska uppnås i silos för hantering av olika biobränslen. Dessutom syftade arbetet till att ta upp två autentiska exempel med flödesproblem och hur dessa kunde designas om för massflöde. För att ta fram riktlinjer har arbetet utgått från värden framtagna av Wu, Schott & Lojdewijks (2011). Dessa har sedan bearbetats i programvaran Silo Stress Tool skapad av Dietmar Schulze (2013) för att utvinna gränsvärden för massflöde beroende av egenskaperna internfriktion, väggfriktion och vinkel på silons ficka. Resultatet visar gränsvärden för massflöde för både cirkulära och rektangulära silos.

Den svenska veteranutredningen lyfter upp mediabilden från Sveriges deltagande i internationella insatser som ett problem. Syftet med uppsatsen är att kartlägga skillnaderna i rapporteringen av händelserna under Operation Artemis i Kongo 2003 utifrån Försvarsmakten och de fyra största dagstidningarna (Aftonbladet, Dagens Nyheter, Expressen och Svenska Dagbladet) samt att undersöka om rapporteringen skiljer sig beroende av om det är en morgontidning eller kvällstidning. Analysen har gjorts utifrån ett narrativt perspektiv och tidningarna har analyserats utifrån kategorierna dagstidningsekonomi, sensationsjournalistik, objektivitet, vinkling och förenkling. Uppsatsen visar på att det finns skillnader i hur både Försvarsmakten och dagstidningarna rapporterade från Operation Artemis. Uppsatsen visar också på att rapporteringen skiljer sig om det är en morgontidning eller kvällstidning som skriver artikeln.
