In this thesis the methane gas potential of three different substrates, two algaes Saccharina latissima and Laminaria digitata and biosludge mixed with paper fiber was studied. This was done by batch experiments in a laboratory environment to examine the gas production and composition of the produced gas.Biogas production is a complex anaerobic digestion process in which various microorganisms decompose the substrate in steps and at the end produce biogas and a residue. Many factors affect the production of gas, for example the substrate content, temperature and pH in the digester.The analysis of methane potential were divided into two experiments. In experiment 1 substrates were digested along with inoculum from Växjö waste water treatment plant in a temperature of about 37 ?C.

This study intends to use a text analysis and analyze Findus crisis communication, on their website, about the horse meat scandal in February and March 2013. The main focus is to examine if Findus crisis communication can be connected to Beniot?s image repair strategies and the rhetorical appeal forms, in five press releases and four blog posts, and also if they are different depending on the media format. The results show that Findus usually used three of the five image repair strategies and the three appeal forms (ethos, pathos and logos) interacted and therefore became Findus crisis communication consistent in all material. The results also show that Findus had a clear position because they conveyed a consistent message..

This thesis describes the redesign ofequipment designed for drying bags thatis used in Fresenius Kabis´manufacturing of their nutritionmedicine in Uppsala. The need of thistask arise during the start of thedevelopment of a new packaging line werethis equipment were meant to be used.

The aim of this study is to examine how social workers and pree-school teachers resonate about their experiences of cooperation with each other, in relation to maltreated children and the duty to report. Several studies show that there is a difference between how many children that is suspected of maltreatment and how many that are reported to social service. In Sweden, pre-school staff are obliged to notify the suspicion of child abuse according to 14: 1 SoL, but previous research indicates that the obligation to declare is not used to the extent that it should. One reason for the low notification rate is  the interaction between preschool and the social services shortcomings.Therefore, we believe it is relevant to examine how the cooperation really looks like between the organizations, when the child is being abused or at risk of suffering. The results of the study are based on qualitative semi-structured interviews with four preschool teachers and four administrators.

Background: The Swedish Parliament passed a law change in late 2010, suspending the former requirement for all Swedish incorporated companies to have an auditor. The new limit values allow the smallest incorporated companies to dismiss the auditor of the company (or not appoint one in the case of a newly started company). The opinions of abolishing mandatory audit vary, and little research has been done post to the law change. However, a new situation has arisen, meaning the optional choice of voluntary audit, for some companies.Aims and research questions: The aim of the thesis is to examine the reasons behind voluntary audit in Sweden, as well as what value companies, having chosen audit, see in their auditor. The following research questions have been used in order to fulfill the aim of the thesis: ?Why do small private owner-led incorporated companies in Sweden voluntarily choose audit?? and ?What value does the voluntarily chosen auditor add to the companies??Methodology: The research questions were formulated after reviewing relevant literature and scientific articles regarding the topic of voluntary audit, as well as the recent law change in Sweden.

This case-study examines the correlation between young men and democratic instability in group discussions with two analyzing methods in one. One part of the method used is deliberative democracy which aims to explain how democracy works within the frames of discussion in ordinary citizens groups. In this study the citizens is upper level secondary school students. The other part of the method used is the theory pulled by many scholars lately, the demographic impact on democracy. With these two combined in one this study compare the theory of young men as more active in political violence and as a destabilising factor of democracy on country-level with the results of the study in deliberative democracy in small group discussions.

The study investigates the use of collection and treatment wagon for piglets in relation to castration. The importance of good and ergonomically designed tools in pig stables can probably reduce the risk of suffering from musculoskeletal disorders (MSD). During the last 20 years the number of pig farms has decreased and at the same time the herd sizes and the number of pig keepers have increased (Statistic Sweden (SCB) 2007). As a consequence, the pig keepers have more pigs to take care of, treat and neuter and spend more of their daily work in these large confinements. This also means that the repetitive work e.g.

The purpose of this paper is to examine how events can be successful and stay competitive.Festivals are a big part of the event world and it can be difficult to understand why certainfestivals are successful and others not. In this paper we have conducted a comparison betweentwo major festivals in Stockholm. Both of them reached success, but nevertheless one of themfailed, while the other one is still successful. With this comparison, it appeared that there aremany aspects that help a festival to reach success but also factors that can make a festival afailure. To conduct this study, a number of interviews have been carried through; these havelater been put in relation to different theories about festivals.

The aim of this study is to investigate which management control mechanisms evolve in companies that receive funding from Venture Capital companies and why the management control systems evolve in the way that they do. A case study was performed on three Swedish high technology companies, that all received funding from Venture Capital companies for the first time in 2006. Merchant?s framework, defining all management control mechanisms as either, results control, action control or personnel control, was used to structure the study. Results show that the companies that received Venture Capital all increased the use of management control mechanisms within results control, action control and personnel control.

This paper deals with archaeological prospection of an Iron Age farm site in Toland, Fresta parish, Uppland County in Sweden. The purpose of the paper has been to see whether the geophysical methods applied (GPR & EM-38) could produce useful results that could motivate its use in similar surveys in the future. Geochemistry has been used for the purpose of identifying possible activity areas on the site. The results have shown that it is possible with a GPR survey to identify postholes originating from the Migration Period longhouse at the site. The combining of several methods have been important for the identification and interpretation of several areas of interest..

In recent years, agile software development methods have become increasingly popular throughout the world. Today there are a number of different agile methods and they all rest on the Agile Manifesto that was formulated in 2001 as a reaction to the traditional software processes.The aim of this thesis is to make a survey of some of the agile methods used today and to see how they are being used in practice. It consists of two parts: a literature study and an interview study with people working in the software business. First, a definition of agile methods is proposed and a number of different agile methods are described. Second, the interviews are being analysed with special focus on communication, collaboration, expectations and results.

The thesis objective was to study the partnership between the municipality of Gothenburg and three nonprofit organizations concerning the mobile EU-citizens. The study examines how the EU-enlargement affected Sweden and eventually the municipality of Gothenburg, and how Gothenburg responded to the new situation regarding the target group. The thesis contains one case study and the empirical data are based on semi structured interviews with politicians and officials from both the public- and the nonprofit sector. The results were screened with New Institutional Theory, Resource Dependence Theory and Decision Making Theory: Rule Following. The theories were used to locate any type of isomorphism, resource dependence and rule following in the partnership.

A study of communication content, frequency and problems was performed at the Swedish Air Force Air Combat Simulation Centre, FLSC. The purpose was to investigate the connection between team communication and performance variables, to study communication problems during air combat and to employ and develop the PILOT method of communication problem analysis. Ten fighter pilots and four fighter controllers engaged in simulated air combat beyond visual range in teams on two sides, Blue and Red, with four pilots and one fighter controller each. Eight such training runs lasting 15 to 25 minutes were analyzed with regard to the Blue team?s communication during launch situations, i.e.

Background:Life-cycle costing (LCC) is an investment calculation that takes intoaccount operating costs throughout the investee lifecycle. LCC calculations are mainly usedto evaluate investments that have no revenue side. Attempts to apply the LCC calculations forbuilding-related investments have occurred since the 1980s. Despite the advantages ofusing LCC calculations, use has not passed through in full. The main obstacles have beenidentified as a lack of relevant input data, and insufficient experience of workingwith LCC calculations.
