Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.

ABSTRACTIntroduction: Violence towards employees in the psychiatric ward is increasing at an alarming rate. Reports concerning the effect on the staff?s psychological health are disturbing. These workforces are those most affected by brutality and for ages it has been looked upon as a part of the psychiatric line of work. This viciousness is threatening the safety for both the personnel and the patients.

This study aims to examine the effect the evaluation system used by the Stockholm County Council, has on how the healthcare providers themselves conduct the evaluation regarding their own operations. This is done through a qualitative case study of the evaluation systems of the Stockholm County Council and of four primary healthcare producers concerning one primary healthcare contract. The evaluation systems were analysed using Merchant and Ver der Stede's (2007) framework for different types of control. In order to give a more detailed picture this framework was complemented with different types of performance measurement. The evaluation that the Stockholm County Council conducts was found to have little influence on the providers own evaluation with the exception of the quality indicators that are rewarded with a monetary bonus..

These days most companies conduct some form of work for the external environment, quality and safety. In connection with this work, some companies have chosen to get management systems certified by any applicable standard for one or more of the fields while other companies have chosen other ways that are not associated with certification.In light of the fact that the individual systems are becoming unmanageable an increasing number of these companies are faced with the decision whether to integrate and coordinate these different systems or not. In order to study the possibilities of a company?s system coordination an assessment of elements particularly interesting for the company was performed. The key elements and focuses in the evaluation were staff access to information, experiences from other companies and environmental work status for some of the organization's companies.

In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.

The purpose of this master?s thesis is to examine how comics, here defined as a combination of text and images, are handled by the libraries in regards to subject analysis, classification and indexing. A comparative approach has been used in this study. First, common practices, methods and theories concerning subject analysis developed for documents consisting of text or images are presented. Then the current systems at two special libraries, specializing in comics and consequently dealing with both text and images, are examined and related to the above mentioned practices, in order to discover differences and similarities.

This Master?s thesis presents a descriptive study of the intellectual process to describe images in such a way that they can be incorporated into written information systems. The purpose of the thesis is to concentrate on the scientific development for the last two decades, in the area concerning the description of images so that they can be organized and incorporated into information systems and possible to retrieve when searched for. Library and information science (LIS) has a strong tradition of turning to the iconographical theories of Erwin Panofsky and to semiotics according to Roland Barthes, for models and theories for the interpretation of images. The question for this thesis is whether LIS in this scientific field, has deviated from these models and theories, or are Panofsky and Barthes and their scientific work still providing for intellectual and practical guidance for LIS within this area..

Palliative care is a care that focuses on providing end of life care but not to delay or hasten death. Despite training, nurses often show a lack of knowledge in attitude, ethics and healthcare issues of palliative care. The nurse in palliative care has a central role in caring of the dying patient and therefore a big responsibility. However, palliative care is a low priority in basic training. The aim of this study is to investigate the roles of nurses in palliative care and if there is a need for increased education in the subject.

This thesis aims towards an understanding of information systems and subject representation in relation to academic disciplines. This is achieved by comparing how a discipline, History of science and ideas, represents itself compared with the subject representation of its dissertations in an information system, LIBRIS. The point of departure for this thesis is the domain analytic view of Hjorland which states that the quality in information seeking is enhanced if the subject representation considers the contexts in which documents are produced and used. The importance of concepts such as domain and discipline is discussed. The disciplines view of itself is established by the study of articles written by scholars in the discipline, by how the discipline presents itself on the homepages of five university institutions and by the examination of titles and keywords given to dissertations in the discipline.

Background: There is a newly founded national sports education program. This newly founded national sports program comprises of several different sports of which football is one of them. Before a football player can reach the European- or national elite the player usually is first developed in clubs and their respective academies where a lot of time is spent on fine tuning the players? individual skillsets.The main goal for the NIU program is to develop future elite athletes to different sports. When it comes to football, the Swedish Football Association and the Swedish school board have together developed a study plan which will serve as a guideline for the NIU-football classes in Sweden.

The main aim in this Master thesis is to analyse how an ideological view may have influenced the shape of hierarchies with a specific concentration on the concept of fiction genre in the latest versions of the systems SAB and DDC. Our thesis is that no theoretical classification scheme can be recognized as objective. With an ideological/institutional perspective we look at the structures behind these systems. As a vehicle we use the hermeneutic circle to show the play between part and unit by focusing and analysing three different levels: the content level the concept level the ideological level. The first level is in the shape of a historical background and an analysis of concept with focus on content.

Allt större och större andel företag väljer att presentera och förmedla varor och tjänster via e-handel. En viktig aspekt vid e-handel är att kunden känner förtroende för e-handelsapplikationen och företaget. Denna rapport redogör för vilken inverkan multimediala inslag har för förtroendet av en e-handelsapplikation, vid initialt användande. En undersökning har genomförts med hjälp av en kooperativ utvärdering av fyra e-handelsapplikationer vilka innehåller olika typer av multimediala inslag har.Resultatet av undersökningen visar att multimediala inslag inverkar positivt på förtroendet för e-handelsapplikationer. Däremot finns indikationer på att för hög grad av multimedialt inslag inverkar negativt på förtroendet för e-handelsapplikationer..

By identifying effects that a buyout-firm has on management control systems in its portfolio companies, the aim of this thesis is to explain how such effects differs between the companies and finally to explain why the effects differs even though the companies are owned by the same buyout-firm. The study is conducted as a qualitative case study based on interviews with representatives from the studied buyout-firm and three of its portfolio companies.By analyzing the empirical findings with frameworks and theories within management control systems and value creation, we cannot only identify effects that are common for all portfolio companies but we can also observe differences between the portfolio companies.The identified effects that are common for all portfolio companies are: increased internal reporting burden, increased perceived risk of getting laid off among managers and co-workers and replacement of the board immediately after acquisition.The effects that are observed only for two portfolio companies are: increased focus on short-term planning, higher financial targets, replacement of company management upon acquisition and moving of decision authorities to higher organizational levels. Differences are observed although the portfolio companies are owned by the same buyout-firm due to: differences in management and co-workers equity stake in the portfolio companies, differences in business complexity and differences in planned exit-horizon..

Computer use at work has risen considerably over the past fifteen years and is currently a relatively common phenomenon when 76 percent of women and 72 percent of men using the computer in their daily work (SCB Arbetsmiljörapport 2009).According to Gulliksen and Göransson (2009), Sweden is one of the countries which are more advanced in the procurement of computer systems at work. He means that Sweden has unique opportunities and conditions for user participation in the development of computer systems, when the user has the right to influence their working environment through a law in the Work Environment Act. The paper examines the importance of user involvement in system development and the Swedish company's approach and experience of user involvement. To highlight and explore the importance of user involvement, there has been a case study in which users have been representative of the development process. The case study has been conducted on a case company where the system IST analys was in need of a new interface.

This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.
