Rheumatoid arthritis is an autoimmune disease, where joints are attacked by the own immune system, leading to chronic inflammation and destruction of bone and cartilage. Inflammation is a complex process, controlled by many different substances. One of them is adenosine, which has anti-inflammatory properties. In this project, three polymorphisms in different genes, involved in synthesis and signaling of adenosine, were genotyped for 188 patients with RA and 362 controls without RA. The results shows that for the polymorphism in A2a, a gene coding for an adenosine receptor, there was no significant difference in genotype distribution between the groups.

The purpose of this report was to compare two different options for expanding of an existing pig farm. For the time being there are low prices within the agricultural market of pig production, and it is interesting to see if it is worth expanding or not. The two different options this report is based on are: expanding from a herd with 50 sows in breeding gilt production to a herd with 100 sows in breeding gilt production (option 1), or expanding to a herd with 140 sows in breeding gilt production (option 2). The number of pregnant gilts produced per year will stay the same for both alternatives; about 300 pregnant gilts per year. The rest of the breeding gilts will be sold at a weight of 25 kg. The pigs that are not sold as breeding gilts (e.g. castrates, and female pigs that are too small or that have disorders) will be kept on the farm as growing-finishing pigs until 120 kg of live weight, and then sold to the slaughter house. By using the existing buildings, even after the expanding, the investment costs, and thereby costs for housing, were kept as low as possible.

Sweden is a world leader in listed private equity and ranked fifth in the world in market capitalization. The sector is attracting increasing interest from the investment community. However, the private equity industry in Sweden has historically poor reputation and is criticized for creating value through high leverage, multiple riding and severe cuts. This study analyzes value creation drivers in buyouts from the perspective of the private equity firm using a dataset of 15 realized buyouts by private equity firms listed on NASDAQ OMX Nordic Stockholm. The methodology used separates the value contribution of leverage on the private equity firm's return from internal operational improvements and external variations in transaction multiples.

The purpose of this essay is to examine the Swedish people?s level of knowledge about crowdfunding and their incentives and deterrents to crowdfunding investments. Early on crowdfunding was divided into two objectives: reward based and equity based crowdfunding. The division of objectives is logical due to the differencing conditions of the motivation for investors to invest. Supported by theories in crowdfunding incentives, commitment-trust, the prospect theory, and the diffusion of innovations, we aim to establish a comprehensive line of reasoning to support our model of motivation in the conclusive chapter.The results of this essay were achieved by a combined method.

The aim of my study is to look at two specific schools and their work with Internet in the classroom and compare their work to what experts say about how you should educate. The study focuses on how teachers guide the students to be critical to the information they encounter on the internet. What do the experts say? How should the teachers work with Internet in the classroom? What do the teachers say about their work with Internet? What do the teachers say regarding children and the Internet?  To answer these questions I have interviewed two teachers from different schools, which had classes with children 6 to 8 years old. The schools are very different from each other concerning investment on Internet devices in the classroom.

Background: The devolopment in the exchange market has attract a large number of investors. The information flow is extensive and it might be hard to follow the dynamic market. Some investors therefore choose to place their capital in a stock portfolio which is manged by a professional firm with no influence from the capital owner, this management is called discretionary managing. Purpose: the purpose of the thesis is to examine the working methods and the rationality regarding the management of the discretionary portfolios. The purpose is also to try to examine whether there is a relation between the selected risk, return and fees.

The residential and service sector in Sweden accounts for approximately 38% of the total energy usage and Sweden has an aim to reduce the total energy use by 20% by 2020 compared to 2008, which means residential sector will have to improve energy efficiency. As part of that a law was instituted by the Swedish parliament that all properties must have an Energy Performance Certificate (EPC) to thereby give the property owners a greater insight into energy use in their buildings and propose recommendations for energy-efficiency measures. On the EPC, a value on the building's energy performance in terms of energy use in kWh / m2 per year is declared, of which electricity is a share of it. Instructions on what to include in the amount facility electricity for running the facilities is regulated by the authority for building, Boverket while SVEBY has made an interpretation of the regulations in their report "Brukarindata bostäder" where they have a table on what should be included in the amount and what not to include.This report is a study of two similar apartment buildings, where one of the buildings recently underwent renovation, to see if the declared amount of energy for electricity, in the EPC, is consistent with the measured value, and whether there has been any reduction in facility electricity in the renovated building after the renovation.The result shows that the measured value of the building electricity was 2.6 kWh / m2 per year, 28,8 %, lower than the declared value in the building that have not undergone a renovation. Calculation of values from previous years (2011) by the same percentage of facility electricity as in the results of the measurements, 56.7%, it becomes clear that the declared value for facility electricity in the EPC of the renovated building do not correspond with reality and that there has been an increase in use of facility electricity after the renovation..

FDI har sedan början på 80-talet växt sig allt större och blivit en av de viktigaste tillgångarna till finansiellt och fysiskt kapital i världen. FDI har enligt många studier en viktig funktion för ett lands ekonomiska utveckling, detta gäller främst för outvecklade länder men också utvecklade länder. Studiens mål var att hitta viktiga faktorer som påverkade FDI inflöde till Sub-Sahara regionen. Den empiriska analysen gjordes med hjälp av en OLS regressionsmodell och hade 42 observationer sammanlagt. Huvudvariabeln var FDI/BNP.

Dooria Sweden AB is one of the main door- and doorframe manufacturers inSweden. They deliver door frames for indoor use for project oriented buildingsites, for these types of building sites the doorpost comes pre-assembled. DooriaAB wants to minimize transport to reduce impact on environment and thetransportation costs of pre-assembled doorframes, this thru simplifying themethod of assembly.The main purpose of this thesis has been to develop a prototype solution thatbrings the three parts of the doorframe together with the same properties regardingstability and tightness of joints as the current method of assembly. A profile ofdemands and wishes were created in collaboration with Mårten Dragstedt, DeputyDirector of Dooria Sverige ABBy following the chosen method the authors have been able to produce a fullyfunctional prototype that meet the demands that were put on the product. Catia V5R20 has been used as an aid during prototype construction and virtual tests.

Properties are bought and sold daily, which means that it is of great importance with rules that regulate the acquisition. The rules on who should be held liable for a property brought to a head when the acquisition relates to a property that is loaded with contaminated soil. The purpose with this thesis is to investigate who could be held liable for contaminated land and also whether an exclusion clause can affect the separation of responsibilities. Two different liabilities can occur depending on which law that should be applicable, MB or JB.MB's rules apply to anyone who may be subject to decontamination responsibilities, which is regulated in Chapter 10. MB.

The purpose of this study is to investigate the perceptions of leadership and gender issues circulat- ing in Womentor leadership development programme, and to have a discussion around what conse- quences they may have on participants' careers. To answer the question I have used a qualitative approach in the form of 10 interviews and non-participant observations. The theories in this study are based on gender and leadership issues.The problem which forms the basis of this study is the underrepresentation of women at senior posi- tions. A basic assumption in this study is that notions of gender and leadership affect the individual's ability to act. The circulating concepts identified in Womentor are: The leader who wants to be a manager, The leader who gets things done, The communicative leader, Change leader, The motiva- tional leader and The leader as a role model.

Göteborg Energi has a surplus of district heating during spring, summer and fall. The heat surplus is due to a constant production of waste heat from oil refineries and heat from waste incineration over the year. It would be desirable to increase the demand for heat and the uptime for the newly built combined heat and power generation plant, Rya Kraftvärmeverk. One alternative could be to integrate Rya Kraftvärmeverk with a pellet production facility. By producing heat, electricity and pellet in a joint process the energy use can be decreased.

Uppsala County has ambitious environmental aims for the planned residential area inÖstra Sala backe. In this thesis different energy sources have been evaluated todetermine which system that would be most favorable given currently availableinformation about the project. Planned energy usage has been divided into tap waterheating, space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios.

The attitudes towards nature conservation in forestry are based on the individual forest owner. The theme of the interviews is the opinion on nature conservation in forestry. The purpose of this study is to identify if there is any difference in attitude to nature conservation in forestry according to the age of the forest owner. The study discusses different factors that affect the private forest owners consideration of nature conservation and give an insight in different generations attitude to nature conservation. Other topics that are discussed is if future change of generation will change the consideration of nature conservation in Swedish forestry and what is needed to enhance the interest in nature conservation among forest owners.This study is the result of interviews with a number of forest owners in the county of Uppsala, Sweden.

The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015. In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well. In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact. In this study three different sanitary systems and the effects of different population growths were compared.
