Design av försöksanläggning för trycksatt rökgasrening vid oxy-fuelförbränning
Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.
Klotter och skadegörelse : metoder och tekniker som förebygger klotter och skadegörelse i offentliga miljöer
The city?s public environments are meant to be perceived as safe and inviting areas to visit any time of the day. In recent decades the number of vandalism complaints has doubled and graffiti has become so common that it received a separate category in the crime statistics. With this type of impacts in the public environments the experience are precarious and a boring sight. It?s difficult to put a price tag on these types of crimes, the number of unreported cases suspected to be large.
Hivprevention - en rätt(vis) fördelning av statsanslaget? : Diskurser om homo-, bisexuella och andra män som har sex med män
The purpose of this study is to explore how different discourses about risk linked to HIV prevention is likely to affect the decisions on the distribution of state funding for preventive activities aimed at 'men who have sex with men' (MSM). This by making qualitative interviews with principals that have an impact on this decision. Using a discourse analytic approach, based on both theoretical and methodological foundations, I investigate the discursive constructions of risk of HIV linked to certain groups and behaviors. MSM is found in the material placed into two different formations of groups, on one hand by the behavior on the other hand on the basis of identity. The identity position is organized discursively from a ?victim? position while MSM provides an "operator" position.

Socialpsykologisk studie om samarbete : En studie om vilka sociala förhållningsätt som är betydande för samarbete i arbetslivet
Our post-modern society is being continually more characterized by the working life, where corporate relations and the understanding of human momentum, limitations and knowledge is the basis of the quality of the corporation. In other words, it is of the greatest importance to keep in mind the attitudes, behaviour, stress levels and motivations that constitute a good working environment. We find it interesting to study what social psychological approaches and social processes could be of importance to good cooperation. The research has its starting point in a qualitative method focused on semi- structured interviews, where we have interviewed eight respondents working within the psychiatry. The research has strengthened our pre-understanding but also made clear the existence of other social processes and approaches that affect cooperation.

Implementation of a Data Handling System for a Scientific Magnetometer on a CubeSat
Since their invention in 1999, CubeSats have become a widespread standard for small picosatellite missions. CubeSats allow for quick development of satellite payloads and launch in space without the high costs of a normal satellite. Emphasis during the CubeSat design process is placed on use of commercialoff- the-shelf (COTS) components and reuse of previously-designed units.This report describes the interfacing of a scientific magnetometer, the Small Magnetometer in Low-Mass Experiment (SMILE) to such a CubeSat mission, the Space Weather using Ion spectrometers and Magnetometers (SWIM). Design of a complete platform for use in multiple such missions is presented here.Modularity is one of the key aspects followed in the course of the work. A new board containing the analog pick-up and compensation circuitry for SMILE has been designed to fit inside a CubeSat frame.
Att rusta sin borg. Förvärv och bibliotekssamling i Vadstena kloster 1374-1595. En studie av resterna.
This paper is a study of Vadstena monastery's book acquisitions and book collection 1374-1595. Studying catalogue descriptions of manuscripts and incunabula in Uppsala University library, the author has aimed to examine the development over a period of time, concentrating on way and place of acquisition, and desired types of texts.A short description and history of the monastery and its library is given. The study opens with the author stating there must have existed a plan for the book acquisitions and collection. A survey investigation shows, that the usable material is too small and somewhat nonrepresentative of the monastery library to form a basis for a fair analysis. Further investigations give material to form a basis for some careful statements, saying that book production and also acquisitions concentrated on sermons literature, and that this type dominated the library collection throughout the time of development, followed by the philosophical-theological university literature..
Kvalitetsredovisning och undervisning i matematik
The aim with this master thesis is to analyze a scientific material concerning the context between learning and child/student development, and factors which controls process of learning, to create an image with quality account and teaching in mathematics, which then can raise the mathematical knowledge among students.The phenomena which stand in focus for the investigation is: why there is a negative tendency for development of knowledge in mathematics, among the Swedish students that TIMSSs investigations showed in intercultural comparison within the years 1993, 1999, 2003 and 2007.The method is the ethnographical method, which is based on: analyzing scientific theories about learning child/student development, factors which controls process of learning, and factors which controls process of learning the most and qualitative empiric investigation with qualitatively analyzes the questionnaires, which is about factors which are controlling the process of learning and factors which are controlling the process of learning the most.Result of the theoretical and empiric analyzes shows that factors as school environment, attitude for subjects and teaching, controls and influence the learning. To end a unenthusiastic tendency as a negative development of mathematical knowledge among students that is shown in TIMSS investigation and to elevate the students' performance in mathematics, an elevated qualitative account and teaching in mathematics, by the factors named. Safe school environments as the intercultural meeting place, the teachers influence part to the students' subjects' attitude in mathematics and goal related grading criteria in teaching, is all required for e qualitative teaching in mathematics..
Obehörig vinst
Unjustified enrichment is used as legal basis when a part claims compensation. Unjustified enrichment can be illustrated as: (A) made a profit on someone else?s loss (B) and if the profit is"unjustified"and has"no legal basis"it shall be returned, which then make it possible for B to claim compensation from A referring to the profit. B has in this case lost something that he owns. To be able to claim A for compensation must the loss of B also be a benefit for A.
