The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

The purpose with this essay is to study police students perception of men?s and women?s role taking and behavior in a group. The question that is presented is if a group?s efficiency can depend on which gender the members of the group have. There are many theories about the concept male and female and the meaning of these words.

Research now shows that the Individual Educational Programs (IEP) are dominated by individual- oriented actions. This despite the fact that the school`s policy documents advocate that IEP should be viewed in context of the school`s activities. Support must be seen from a holistic perspective and the student`s difficulties will be related to the whole school environment. In an attempt to understand why the individual- oriented actions are still there, I have studied how specific IEP are formulated, and how it relates to the school`s policy documents.In the study, I used discourse theory as a method. By examining the I E P in educational activity, I wanted to find the meaning with which the concept of individual, group and organizational level were filled.The results show that the IEP in comparison with the policy documents mainly differ on the definition of group and organizational level.

The purpose with this thesis is to demonstrate that other factors than the existing set of rules could influence the Management Group?s decision in regards to depreciation of goodwill. We have explained the conflicts between the management group and the stakeholders by using the Agency Theory and the Stakeholder Model. We have used the Positive Accounting Theory to describe how the management group?s opportunistic behaviour decides which accounting method to use.

Dancewalks är ett platsspecifikt danskonstverk skapat och uppfört i olika semioffentliga rum. Den här kvalitativa studien undersöker resultatet och effekterna av en Dancewalks i Malmö där 30 arkitekter och stadsplanerare deltog. Dancewalks är i sig själv ett performance vilket påverkar studien och därför också undersökningsprocessen. Det teoretiska ramverket utgår från Non representative theory och teorier om hur människor interagerar i rum. Tillvägagångssättet för studien är en triangulering av observation, fokusgrupp och semistrukturerade intervjuer.

It's not a secret that most companies strive to get such a high economic return as possible. To successfully engage in a profitable enterprise, there are many elements that come into play. An important element is the motivation of the employees and their work performance. Work motivation is a key factor for the employees to improve their performance and therefore determinant for the successes of the company.This work is a case study in the production at Fresenius Kabi, Uppsala. The work is based on an employee survey that they fill out once a year and the aim is to develop a deeper understanding for these questions and how the employees see on leadership, communication and goal-setting as motivators and how these factors works in the company today.To get this deeper understanding I have used a qualitative approach.

The thesis examines how language, culture and family structures interrelate and affect the process of migration. Vital is how women from a different ethnic background integrates during migration and in a dialogue context with us as researchers and native Swedes. The thesis is interdisciplinary and analyzes empirical data through a qualitative method by using the perspectives gender, ethnicity and identity. The empirical material consists of 7 interviews, which have been transcribed and then broken down in to quotations. Thesequotations have then been analyzed using the perspectives mentioned above.

The purpose of this randomized controlled study was to investigate the effect of internet- administered guided self-help for women suffering from psychological problems following traumatic childbirth. The eight-week treatment program consisted of written chapters based on cognitive behavioral therapy. 56 participants were randomly assigned to a treatment group (n = 28) or a waiting list group (n = 28).The results showed that post-traumatic symptoms decreased as a result of the treatment, with large within-group effects measured by both the Traumatic Event Scale (TES) (d = 1.33) and the Impact of Event Scale-Revised (IES-R) (d = 1.3). The difference between the groups was only significant when measured by the IES-R in which case the between-group effect was large (d = 0.97). The proportion of the participants who showed clinically significant improvement was considerably greater in the treatment group than in the waiting list group.

In this thesis, input data for energy performance calculations on commercialpremises have been studied. In energy performance calculations, where internal heat gain parameters are unknown, template values that, in a reasonable way represent the activity in the room, are necessary. These values can be used as input data for whole-year calculations, or for calculations on shorter periods of time.The purpose of the Sveby project is to create standardized work practice in energy issues for the construction industry. The work in this thesis is conducted to correlate with the purpose of the Sveby project, with aims of contributing with information and guidelines for the continuing work with commercial premises.In this report, suggestions for template values for internal gains parameters, based on research and calculations in the field are presented. Suggestions on how these can be implemented in a user-friendly way for two energy performance calculation software are also given, VIP Energy and IDA ICE.

My purpose with this study was to research how a few teachers work with the children in preschool class to achieve a group that the children feel safe and comfortable with. Every human being has got the need to feel safe and with this study I want to illustrate the importance about working to achieve safety for children in preschool class, and environment that is new to them. In order to try to get answers to my research questions I have interviewed five preschool class teachers. The results showed that the teachers work in a way that makes the children feel safe by helping them establish the daily routines and common rules for the preschool class. They also let the children in the preschool class get to know each other and other children in the school by play and shared activities.

Heat stress negatively influences the performance of dairy cattle such as lactation and reproduction. Heat stress can cause production losses as well as welfare problems. Years of research have shown that heat stress is a huge problem for dairy cattle in both the tropics and temperate zones but no such research have so far been done in northern European countries. It seems like shade is an important tool when improving pasture conditions and therefore deserves more attention. The aim with this study was to investigate whether there is a need of providing shade for grazing dairy cows during the summer in Sweden. Two groups of lactating Swedish Red dairy cows (n=15 per group) were kept on pasture.

The aim of the study is to investigate attitudes about rapists and to determine whether it is felt that they need treatment, imprisonment or a combination of the two. The study examines differences in attitudes between two different educational groups. The first group of students is comprised of those studying on programs that lead to careers working with people, whilst the other contains students who will work in business administration. The investigation also includes views on which punishment alternative the informants believed to be the most appropriate. The same differences are also investigated between gender and age.

This thesis investigates in which way principles and theories of usability is revelant when evaluating interactive systems for children aged 10-12. It also investigates whether there are specific factors that you should keep in mind while developing interactive products for the targeted group.The results of the qualitative study shows that priciples and theories of usability is relevant when evaluating interactive systems for the targeted group. However there is one concept that is more significant than the others. Our study shows that our targeted group is sensitive to time-consuming activities such as loading times etc. which has to do with the efficiency of the system.

This is a qualitative study designed to investigate how professional support group leaders talk about their role as supervisor of support groups for children and adolescents with problematic home situations. We also examine how these supervisors talk about the method they use and how they talk about the individual child. We have chosen critical discourse analysis to help us explore if there are different ways to talk about these territories. Our questions are:How does the support group leader talk about his role?How does the support group leader talk about the method?How does the support group leader talk about the individual child?The theories we have chosen to use in the analysis of our material is Aaron Antonovsky's Sense of Coherence and social constructivism.
