In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.

How does the computer influence teenagers' lives. I interviewed five young people, and gave a questionnaire to another 47, about this.What I found was that they were aware of and handled well the risks with the Internet and the computer, but had problems with the computer taking too much of their time. They wanted more time for their families and outdoor activities. It was mainly the Internet that seemed to have an influence on the teenagers, not the computer as a machine. They told me that there was a rough climate on the Internet, partly because of the possibility of being anonymous.

The aim with the study has been to get an overview of how students perceive their learning in group projects. The survey has been implemented with a quantitative questionnaire with qualitative elements during guidance. Students in grade 9 in a secondary school answered a survey study where they should take side to several proposals about learning and group work. The result shows that students in general do not find learning in group as the best learning method, but instead prefer individual learning methods when to learn new things. On the contrary, students claim that they learn best when group members not think as they but think in another direction.

How the United States anti-terrorist strategy is affecting the view of democracy is the main analysis of this paper. The mechanisms that affect the idea of democracy have been studied on the basis of the philosopher Michael Foucault?s thoughts and the main direction in French discourse analysis. The study is restricted to the period between the 11th of September 2001 and today. Information has been collected entirely from the White House?s website http://www.whitehouse.gov, including speeches, conferences and reports.

Risk-free profit sounds appealing. The opportunity to arbitrage exists. Investments in underpriced IPO:s can generate profit, but for whom?Previous studies have shown that underpricing is a common phenomenon. This study intends to investigate whether underpricing and the arbitrage opportunity exists on Aktietorget which is a smaller venue.

The purpose of this master thesis is to evaluate how the current share price and market consensus affect security analysts target price and if an investor should pay any attention to it. Empirical data is primarily collected from qualitative interviews with ten security analysts but also from a quantitative e-mail survey. Our main finding is that security analysts are indeed affected by each others earnings forecasts as well as the current share price. This is not strange, it is in several aspects rational. Security analysts has often nothing to gain by standing out too much and not either by spending too much time trying to create their own opinions due to lack of time or the complexity of what is analyzed.

Marks do not only work as an acknowledge of the effort that has been made under a long period of time, but also as a receipt for eligibility to further studies. Within the political debate, marks have often caused a big discussion among the political parties. That is due to the obvious difference between the political parties on the left, and their counterparts on the right. However, there is one thing that they all have in common. Everyone of them have plans of measure within their political agenda, regarding the use of marks.The aim of this study has been to try to understand the way pupils think about marks.

Every business is subject to service failures. The process of correcting these failures and turning disappointed customers back into happy ones is called service recovery. This is particularly important in the hotel business, where there are many moments of truth where customers may become dissatisfied. To further complicate things, service recovery is a process where you may have to correct errors of others - people beyond your control. The research field is relatively new and there are no turn-key solutions as to how to systematically work with service recovery.

AimThe aim with this study was to acquire knowledge of mental training and if you can use it in the elementary school to increase in a short period of time the performance in a coordination test. Furthermore we wanted to investigate teachers understanding of the possibilities to perform this kind of training in the elementary school, and if there is support for this in the school regulation.MethodAs method we have used a combination of a literature pre-study, interview and at the end an experiment. Before the experiment and interviews could take place we studied literature about mental training to get a basic knowledge of the subject. The facts we learned from our pre-study and interviews gave us the base for our experiment. The experiment group included 23 pupils in a third class at school situated in Stockholm.

Background: Several accounting scandals have caused a development from rules-based to principles-based regulation. Swedish municipalities follow the principle-based recommendations issued by RKR (The Council for Municipal Accounting). An explicit requirement of component depreciation has been introduced prior to 2014. The principles-based regulatory framework raises some choices regarding the introduction and demands that professional judgments are made. There is some risk that comparability decreases.

The purpose with this study was to analyse students' conception of living things, and to establish how a social constructivist learning situation affect their conceptions. The method consisted of questionnaires, followed by group discussions and a final survey. The main result was that students have everyday conceptions about scientific phenomena that are reinforced by the social interaction. Some students were positively influenced by the interaction with their peers, where non-scientific conceptions were replaced by conceptions of a scientific nature. Furthermore, the cultural artifacts are of very good means, but the study showed a strong need for a knowledgeable person, e.g.a teacher, to guide students in the right direction during the discussions.

AbstractWorking as a lawyer demands not only legal skills, but also ethical ones due to the involvement with humans. The area of ethics is far from as regulated as the area of law is. The reasons for this are both historical ? as the area of ethics is, in comparison with the practice of law, a relatively new area, especially combined with the traditional work of lawyers ? and technical, since ethics is an area that seems difficult to regulate due to its adopting skills. Ethics looks different depending on which work area it addresses; who you ask; and in what situation it shall be enlightened.

To assure good quality the software needs to be tested to find errors and to verify that the programme meets the customer?s expectations. Traditional methods are usually used in software development and means that a number of predetermined steps are followed. By using agile methods the development can more easily be adapted to the changes on the market. With these methods the testing is carried out continuously throughout the project.

In this work, I describe the factors that affect the bucking of pine logs on the basis of the machine operator. The aim is to find an explanation why the bucking differs so greatly between requested length results and the actual length results in pine bucking. The used methods in this study were data from simulated pine outcomes, data from earlier length outcomes and analysis of the harvesters' PRI files. This is to identify the problem. To explain the background to the problems a qualitative research interview was used.

Slopandet av revisionsplikten har lett till att små bolag står mellan valet att anlita revisor eller inte. Studiens syfte har varit att utforska hur den upplevda nyttan med revision påverkar valet att anlita revisor eller inte för etablerade och nyetablerade bolag. Undersökningen genomfördes genom en kvalitativ undersökningsmetod vars syfte var att få en djupgående förståelse för vilka faktorer som påverkar valet att anlita eller inte anlita en revisor i etablerade samt nyetablerade bolag. Genom intervjuer har studien undersökt vilka faktorer ägarna i både etablerade och nyetablerade anser påverkar valet att anlita revisor. Studiens teoretiska referensram är baserad på agentteorin, legitimitetsteorin, institutionellateorin samt intressentteorin. Referensramen ligger sedan till grund för insamlingen av empiri och genomförande av analysen.
