Swedish biogas is currently produced mainly by anaerobic digestion of sewage sludgeat sewage treatment plants, landfills and anaerobic digestion of household or industrialwaste. Also cattle ma-nure from farms can be used to produce biogas. Upgradingbiogas represents an increase in methane concentration from about 65 % to about 97%. In addition, particles and contaminants must be sepa-rated from the upgradedbiogas. There are various methods for upgrading and this report compares sixdifferent methods with respect to environment and economy: water scrubber,Biosling, cryo technology, chemical absorption, Pressure Swing Adsorption (PSA) andmembrane separation.According to the used ORWARE model, chemical adsorption with amine has the leastenvironmen-tal impact (methane emissions) and the lowest costs.

When a child is hospitalized, it is usually more than one person who needs attention ? i.e. the child as well as its parents. The emergency ward environment and surgery rooms are unfamiliar and the parents feel anxious, insecure and uncertain about how to act. They are expected to participate in the child?s care, cope with their own anxiety and simultaneously convey a sense of security and stability to the child.

The aim of this study is to investigate and analyze the potential effects on a number of social workers that may arise from listening to stories of domestic violence, and how these social workers deal with the potential effects. The study is based on qualitative interviews with seven social workers that work with domestic violence. The theoretical perspective that we used was the theory of coping. The results of this study have indicated that the respondents have been affected of listening to the stories of domestic violence. Examples of different impacts that the work has had on some of the social workers is that they avoid movies and/or books with elements of violence, they are more aware of the domestic violence in the surroundings and there has also been changes in their cognitive schemas.

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

Rapporten har ett fokus på Byggnads Informations Modeller (BIM), ett IT-tekniskt verktyg och arbetssätt som har vuxit fram i byggbranschen alltmer under de senaste åren. Hur detta IT-verktyg används hos medelstora byggentreprenadföretag redovisas i denna rapport.Syftet med rapporten är att verka positivt på utvecklingen mot effektivare och resurssnålare arbetsprocesser inom byggbranschen genom att bidra med kunskap om hur användandet av BIM ser ut bland dessa företag, varför det ser ut som det gör, ifall BIM behövs och vad som kan förändra läget i någon riktning.Metodarbetet har bestått av litteraturstudier och intervjuundersökningar.Arbetet inleddes med studier av rapporter och texter relaterade till BIM och intervjuer med representanter för ledande branschföretag inom bygg samt ett par branschorganisationer med inriktning på BIM. Därefter följde ytterligare litteraturstudier med inriktning på förändring och förändringsarbete och enkät och intervjuteknik. Arbetet ledde fram till olika grundteser och förklaringsmodeller som låg till grund för och utformade de intervjufrågor som ställdes vid huvudintervjuerna med elva medelstora byggentreprenadföretag.Huvudintervjuerna gav ett resultat som visade att företagen generellt sett såg på BIM som något positivt, med fördelar såsom lättare kommunikation och som ett hjälpmedel att minska fel i produktionen. Resultatet visade även att det fanns utmaningar såsom mjukvarukompabilitet och en beroendeproblematik mellan projektets involverade parter som innebar att för att tekniken ska kunna ge fördelar måste alla parter använda tekniken.Förklaringarna till det låga användandet bland medelstora byggentreprenadföretag var flera, vanligast var brist på krav från beställarna.

Social media, such as Facebook, Instagram and Twitter, have become popular platforms for social communication, and, increasingly, also important channels for business marketing. For a business intending to use social media for marketing, however, developing a strategy and building a trademark can be a challenge. This report describes how a small, newly established business enterprise can develop a digital strategy with clear goals and practical guidelines. The report describes a digital strategy for Gelato Scarfó and shows how this strategy is made concrete through a set of guidelines. The guidelines develop a trademark for identification and loyalty, and give advice on how new materials can be made consistent with the trademark..

The aim of this Master's thesis is to examine and analyze what discourses about children that can be found in three Swedish culture publications, and also to identify the different social roles that are attributed to children in these publications. The theoretical and methodological background is discourse theory, as described by Ernesto Laclau and Chantal Mouffe. Additional theory used is social constructionism and Norman Fairclough?s critical discourse theory. Three questions are asked: What discourse/s can be found in these publications? What do these discourses tell us about the view on children within the library domain? What social roles are attributed to the children in the texts and what consequences do these have for the power configuration between children and adults? Furthermore there is a discussion concerning what effects these discourses might have on the direct and indirect reception of children in the library.

This survey was made to investigate the possibility of using an alternative method of fencing inSwedish forestry. The most common way of fencing in Sweden today is made by a two meter highmetal net that is attached to turned impregnated poles. The fencing methods that have beeninvestigated is a fencing system made completely out of wood so called ?German wood fence?.Browsing of game in forest regeneration areas is often a big problem and some kind of protection ofthe plants is often necessary. There is several ways of building fences and the most common way isto use metal nets and impregnated poles, this leads to a problem when the fence has profiled itspurpose.

Hudiksvall Municipality will build a new preschool. The goal is that the pre-school should reflect the municipality's environmental goals and meet building regulations. The wall structures that are compared in the report is an insulated wooden frame and a frame of lightweight concrete blocks from H + HWall structures are compared within the areas of U-values, air tightness, thermal storage capacity, fire ratings, moisture, durability, emissions and environment. In these categories the two wall structures will be rated in a scale from 1 to 5 and then the categories are weighted against each other. The weighting is based on Hudiksvall Municipality's assessment of the categories importanse for their final selection.The results of the comparison show that the concrete structure is recommended for the construction of pre-school with 27.55 points against the wooden structures 23.70 points.

The purpose of this study is to increase the understanding of how venture capitalists can use their network in order to reduce information asymmetries between themselves and the venture management team. A qualitative approach with semi-structured interviews, consisting of open questions, have been used to receive gradate information in order to reach our explorative purpose. Our theoretical framework consists of relevant studies made on the dynamics of networks and the problems that can arise in the complex relationship between a principal and an agent. We have been interviewing two venture capital firms and therepresentatives from two business angel networks. We also made an additional interview with an influential financial actor in order to try to verify our conclusions Our conclusions are that an extensive network can be used by venture capitalists in order to; verify ventures? technologies, complement the competences in the venture management team, and arrange co-investments, resulting in reduced information asymmetries between themselves and the venture management team.

In the thesis we have shown that it is possible with current technology, to buildneighborhoods that are largely self-sufficient. We have obtained some information aboutongoing work in the field of energy efficient buildings and active house which we have usedto develop a model. The feasibility study for Ranagård we have e.g been forced tofollow laws on groundwater covered, resulting in the construction of basements for singlefamilyhome is not possible. The model that we have built up overtime has been the central part of the work. The model illustrates very well what an activehouse neighborhood means and potential of such an area.

This master thesis project will describe and evaluate the interfaces between applications and Controller Area Network, CAN, interface boards from different manufacturers. The interfaces have corresponding functions but the usage of parameters is different. The simply communication of sending and receiving messages is more alike than the supplementary functions between the different interfaces. The CAN communication is more controlled by the CAN protocol and is therefore more alike. The evaluation shows differences and similarities between different interfaces and also difficulties and options to translate them.

The hillforts of Bohusl?n are numerous, yet few have been studied, leaving gaps in our understanding of their dating, morphology, and connections to nearby prehistoric sites. With the help of settlement archaeology, the aim of this study has been to analyse three hillforts on Hisingen and answer these questions. This was done by observing the location and morphology of the hillforts and by analysing the age and functions of nearby prehistoric sites within a kilometer of the hillforts. The results indicate that Bj?rlanda 22:1 and Torslanda 56:1 were likely ritualistic enclosures, while Torslanda 15:1 had defensive functions.

Staden Sulaymaniyah ligger i den kurdiska delen av Irak och har på senare år utvecklats då många valt att flytta från landsbygden till den centrala delen av staden. Nybyggandet sker under tidspress och långsiktigt hållbara lösningar prioriteras inte. Målet är att ta fram ett hus som är anpassat för majoriteten av befolkningen och samtidigt få ett bra och energieffektivt inomhusklimat. En faktainsamling genomfördes för att ge bakgrundsinformation till projektet. Vidare gjordes en planlösning till huset i AutoCAD vilken har använts som grund till utformningen av huset och smarta lösningar.
