To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

The concept of national security has been a matter for debate during recent years, especially in academic fields. Criticism has surfaced since the end of the cold war, directed towards the traditional perspective's dogmatic focus on armed threats and interstate war. Questions concerning an oncoming paradigm shift have been raised, regarding a widening of the security agenda among national states to also include alternative threats, such as environmental hazards. In this thesis, the focus lies on the effects that climate changes have caused in the Swedish national security agenda during the last 15 years. Swedish policy documents show that there have been some major changes, not only the widening of the security agenda but the entire security domain seems to have changed.

The challenges facing low voltage grids are rising as an increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power in mind for the transportation sector. One of the most important tools for this transformation is widely regarded to be the electric vehicle. With the demands of the electric vehicle pressuring the power grid, several questions arise regarding the growth of the electric vehicle market and what repercussions it may have on the grid. This paper focuses on a typical low voltage grid in southern Sweden and what effects a growing electric vehicle market may have on it. Through computer-assisted simulations based on several future scenarios regarding the EV market, this paper finds that few modifications and reinforcements are needed on this particular grid within the next 10 to 15 years.

Dragbänken installerades på avdelning kallbearbetade rör på Ovako i Hofors 1990. Sedan dess har kvalitetskraven på de dragna rören ökat. Samtidigt har produktivitetskraven ökat, det vill säga att tillverka rör till rätt kostnad. I produktionsplaneringsprogrammet finns gränser och regler för hur de dragna rören ska tillverkas för att rätt kvalitet och kostnad ska uppnås. Eftersom både de dragna rören och de varmvalsade ingångsrören har ändrats med åren så stämmer inte alltid gränserna och reglerna idag.

This study aims to map the opinions and attitudes of lokal elected officials regarding corruption and corruption preventing measures. The study also attempt to determine weather opinions differ based on the interviewed party political affiliations. The study material of the thesis is therefore largely based on interviews with elected representatives from the municipalities; Älmhult, Lessebo and Tingsryd.  .

AbstractThis study examines the conclusions made by Roland Paris in his case study of fourteen major post-war reconstruction efforts following the end of the Cold War, and applies them to the current reconstruction process in post-war Iraq. Paris found a common denominator of the fourteen cases ? a belief that a rapid liberalization process, turning war-torn states into liberal market democracies, would foster sustainable peace. Paris calls this belief ?Wilsonianism? after Woodrow Wilson, who was one of the first advocates of it.

The aim was to identify if the veterinary nurse is as competent as the veterinaian in placing a nasoesophageal feeding tube. The aim was also to identify the complications with malnutrition and the advantage and disadvantage of the procedure. This essay is based on several interviews with both veterinary nurses and veterinaries. 16 persons were asked 4 short questions in conjunction with an intensive care/emergency and surgery congress in Gothenburg in February 2013. In addition 4 major hospitals that provided intensive care were asked to answer 5 more detailed questions, one answer from a veterinary and one answer from a veterinary nurse was requested.

The establishment of loan-based structures within a group of associated enterprises with the purpose of lowering the group's taxes by using deductible interest payments to transfer money has become increasingly popular in Sweden during the past few years. The legislator has therefore implemented new laws which restrict the amount of interest payments that are deductible within a group of associated enterprises. As a consequence the definition of associated enterprises has become of high importance. The definition has been criticized and is perceived by many as vague and difficult to interpret. The purpose of this thesis is to examine the definition of associated enterprises in Swedish tax law with the aim of clarifying its scope and meaning.

The purpose of this thesis is to explain why states obtain nuclear weapons and the role variousactors and interests play in the making of states´ nuclear policies. The main questions are asfollows: (1) What big theories exist concerning states obtaining nuclear weapon and nucleararmament in International Relations and what relevance do they have of the post cold-war period?,(2) What is the meaning of the perspective of the Military-Industrial Complex (MIC)?, and (3)Arethere empirical studies which supports the existence of a MIC in the United States?The focus lies on actors and driving forces that are internal to states and it is also important toinvestigate if the theories have relevance for the post 9/11-era. The study uses the method ofqualitative literature-study with some quantitative segments. It is claimed that states might beinterested in justifying their behaviour in a morally appealing way and that real reasons may behidden.

Background: At this present moment, one of the largest changes in the Swedish employment market is occurring, as the people born in the 1940's are retiring. The Generation Y, people born in the 1980's, will enter. Will this have an affect on motivation and leadership, and in that case, in what way Aim: The purpose of this essay is to investigate whether or not Generation Y (born in the 1980's) has an effect on the perceptions on how to lead and motivate employees. Based on research and our empirical results from qualitative interviews at one of Sweden's largest banks, our research questions are:1. Are executives' and employees' perceptions regarding Generation Y in line with previous research 2.

Participating in peace support operations has been and remains a significant part of the Swedish defense and security politics. Since the end of the Cold War, the Swedish national defence has been more and more dismantled, in favor of international peace support operations which have become an increasingly important task for the Swedish defence. Why then, is Sweden so engaged in conflicts so far from home? Using two classic theories of international politics, realism and liberalism, this study aims to shed light on arguments from the Swedish parliament on why it is important for Sweden to participate in international peace support operations. After analyzing arguments of the Social Democrat Party, the Moderate Party, the Green Party and the Liberal Party concerning three different peace support operations which Sweden has participated in, the result shows that although both realism and liberalism are influencing the parties? argumentation, liberalism is the theory which is used more often.

This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess heat to a nearby district heating system were investigated. It was found that in all investigated cases except two, the data center could be cooled solely with free cooling for at least 300 days a year when only the outside air temperature was considered as a constraining factor. The limit was then set to 20 °C.The vast majority of all district heating systems in Sweden get little to none of their heat from other excess heat sources.
