Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.

In today?s technological society, there are increasingly less physical demands on the locomotor system. However, despite that notion strength and function in the hand?s complex biomechanical system are in fact both needed to cope with daily life. The grip function is a main function in the hand and is used in many examples of scientific research, for instance when assessing physical health and predicting the probabilities of premature mortality.

The primary aim of this thesis is to examine female lawyers' relationships to information from different angles. The starting-point is that the legal information, retrieved from through different information sources, is not free from values and subjectivity. The commonly presumed objectivity of legal information is questioned, based on the fact that this kind of information has developed and changed historically in the context of, and in relation to, society. Another aim is to find out how the female lawyers experience their situation in a traditionally masculine working environment. Qualitative interviews have been carried out with seven female lawyers involving questions about their daily work about the sources that they are using.

The purpose of this Master?s thesis is to examine what role the new city library in Halmstad has for its users. The questions posed in this study are: What do the users actually do at the library? What roles are the most significant according to the users? Have the politicians succeeded in their intention of realizing a modern library according to the users? The theoretical starting point is Andersson?s and Skot-Hansen?s theory of four different roles of public libraries. In order to extend the model we added a fifth function; the one of aesthetical experience.

Internet has made information more easy to get, but also more difficult to retrieve. There is a need for information retrieval systems that assure accurate, reliable and up to date information. Quite a number of both commercial and non commercial search services has been developed on the Internet. We have made a qualitative study of one for-pay product in particular, NetS k, produced by BTJ (Bibliotekstj nst), Lund. It is a database that contains collected, evaluated and classified links, and is especially developed to suit public librarians in Sweden.

The purpose of this essay is to examine how high school students (age 13 to 19) search for information on the web and in databases. Furthermore, it aims to look into how critical of sources they are. The questions asked was: how the students search for information in digital media? Which kind of sources do the students use? How they evaluate the information they find? Do they get any education in information retrieval and source evaluation? To answer these questions students were interviewed in groups about their information retrieval behavior. Furthermore two school librarians were interviewed about their experience of the students? information retrieval.During the interviews it was clear that the students had received quite sparse instructions on the subjects of information retrieval and criticism of the sources.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Does low fat dairy products reduce blood pressure?Author: Emma Bergman and Naman LimaniSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 26, 2014Background: It is estimated that at least a third of the population in Sweden have a high blood pressure with genetics, unhealthy diet and physical inactivity as the main contributing causes. High blood pressure is one of the greatest risk factors to develop cardiovascular diseases, which is the leading cause of death worldwide. Milk is a nutritional food product and previous research suggests that low fat dairy products may have blood pressure lowering effect.Objective: The aim was to examine the scientific basis of how low fat dairy products affect blood pressure.Search strategy: Twelve searches were conducted on PubMed and Scopus, where the chosen search terms were combined to produce a broad search as possible in the particular area. The search terms used were dairy, dairy products, milk, blood pressure and hypertension.Selection criteria: Studies on normotensive or hypertensive individuals who received low fat dairy products were included.

This thesis examines the National Heritage Board in Sweden and the way they look upon themselves, the surrounding world and their mission. Methodologically it?s a discourse analysis based on poststructuralist and social constructionist thoughts. This means, simplified, that nothing is taken for granted and that power relations and ideology always matters. There is no true or distinct heritage.

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.
