Målet med detta examensarbete, utfört på uppdrag av Vectura Consulting AB, har varit att undersöka möjligheten att ansluta en vindkraftpark till järnvägens kontaktledningsnät. Möjligheten att koppla om vindkraftparken till järnvägens hjälpkraftnät, som bland annat förser växelvärmare och signalsystem med effekt, har också undersökts. Eftersom kontaktledningsnätet och hjälpkraftnätet arbetar med olika frekvenser och spänningar, 16? Hz och 15 kV respektive 50 Hz och 22 kV, måste därför en komplett krets för frekvensomvandling, spänningsomvandling och omkoppling tas fram. Projektet har begränsats till en del av Botniabanan, sträckan Örnsköldsvik-Nordmaling.I denna rapport har trafikfrekvensen på den valda sträckan på Botniabanan undersökts för att bestämma en genererad effekt till inkopplingspunkten, samt för att undersöka när det kan vara lämpligt att koppla om till hjälpkraftnätet.

Rheumatoid arthritis is an autoimmune disease, where joints are attacked by the own immune system, leading to chronic inflammation and destruction of bone and cartilage. Inflammation is a complex process, controlled by many different substances. One of them is adenosine, which has anti-inflammatory properties. In this project, three polymorphisms in different genes, involved in synthesis and signaling of adenosine, were genotyped for 188 patients with RA and 362 controls without RA. The results shows that for the polymorphism in A2a, a gene coding for an adenosine receptor, there was no significant difference in genotype distribution between the groups.

Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

 Every day media reports acts of violence in various kinds. Crime statistics shows that threats and violence are increasing in regard to both frequency and intensity within the nation. Nurses in the ambulance service are often the first to meet with a patient, therefore these nurses often find themselves in situations where violence and threats occur or have occurred. Drug addiction or some kind of illness are often reasons behind threats and violence.Earlier studies within this area of knowledge are mostly foreign and therefore little describes Swedish nurses` experiences of threats and violence within the ambulance service.The purpose of this study was to describe nurses experiences of threats and violence in the meeting with patients within the ambulance service.The study is a qualitative interview study performed within the School of Life Sciences at the University of Skövde. Six nurses were interviewed with the criterion that they should have experienced threats and violence within their occupation.

Relationships between defence mechanisms and body movements were investigated in regard to three hypothesis; I. that a difference in frequency of body movements correlates to different signs of defence mechanisms, II. that themes of body movements can be identified in regard to signs of defence mechanisms, III. that no significant differences will be found between the different groups of gender. The aim of the study was to seek a relation between quasicommunicative body movements and defence mechanisms.

Introduction: Basic Body Awereness Therapy (BBAT) is a treatment developed to treat different kinds of psychiatric diagnoses, but also to prevent the emergence of any other unhealthy conditions. The treatment is aimed to increase the body control and conscious breathing but also requires mental awareness.Aim: The aim of this study is to, based on social cognitive theory, describe patients' experiences of BBAT performed as group therapy.Method: The study design was qualitative with an inductive approach. Five people were interviewed after a BBAT group treatment in primary care. The data was collected by individual interviews with semi-structured questions and the interviews were analysed by qualitative content analysis.Result/Conclusion: The participants experienced increased body awareness and implemented BBAT strategies even though the treatment frequency was insufficient. BBAT was described as helpful used to regulate intensity level, stress management and facilitate breathing.

The purpose of this essay is to further the understanding of contemporary management theory by conducting an analogy-study of the source to many of the terms today used in knowledge-intensive companies. The way a football club deals with knowledge work differs from how a conventional company deals with it. However, many of the terms, such as teamwork and coaching, are shared by the two types of organization. By using the analogy-method we hope to create a wider understanding for the shared concepts. We have used a hermeneutic perspective throughout the essay, which first and foremost means that we focus on understanding and explaining social phenomenons.

Studies show that older is an increased proportion patients in hospital and that it is a patient group that can be difficult to communicate with because of older patients' often multiple disease picture. Relatives to the patient can be help for caregivers in the communication and the care of the patient. The aim with the study was to examine relative's experience of participation, meeting/support, accessibility and information on a geriatrics rehabilitation care unit. The study had a descriptive design and was designed as a questionnaire study. It was implemented on one geriatrics rehabilitation care unit on the countryside in central Sweden, belong to Uppsala University hospital.

Sustainability work is something that is emphasized more and more. Corporate Social Responsibility, CSR, is discussed and the question of how much responsibility companies should really take is frequently in the news. Companies tend to ask themselves how much responsibility they should take. CSR is a common concept of companies environmental and social work and a concept we tend to see here and there in our modern society. CSR includes companies? social responsibilities, both in terms of carbon footprint, working conditions, social responsibility and more.

Title: What is important knowledge in social studies- An analyse of opinions among teachers in social studiesThe aim of this paper is to increase the awareness about how teachers in Social studies think about goals and substance in the subject. I also want to get a picture about what kinds of problems teacher?s experiences when teaching Social studies. My expectations told me that Social studies are complex to teach, because it derives from several university disciplines such as Political science, Economics, Sociology, Law and Geography, which I believe makes the subject harder to define and what to give priority to. Finally, I want to increase the awareness, if it seems to be any fundamental essence in Social studies as a subject.To achieve my goals with this paper I have studied relevant literature about Social studies.

The aim of this study is to describe how nature is portrayed in swedish poet and critic Aase Berg?s two earliest poetry collections, Hos rådjur (1997) and Mörk materia (1999), and how it relates to notions of humanity, culture and civilisation. The concept of ?nature? is problematized in a short survey of how it has been used by and critizised in ecocritical literary theory, which is used as the main theoretical framework for this survey, with an emphasis on selected theoretical concepts by Donna Haraway. As a methodological starting point, ?nature? is tentatively defined as ?that which does not let itself be subsumed under the human, culture or civilisation?, and this definition is contrasted with how the concepts are handled in the texts.The investigation shows that the relationship of nature to the human is a fundamental theme that provides a structure for both poetry collections.

AbstractThe aim with the study was to describe and to compare nurse students' views about importantcaring behaviors in order to give good caring. An empirical comparative study wasimplemented on a college in the middle of Sweden. Nurse students in the beginning and at theend of their education sorted and prioritized 50 caring behaviors (CARE-Q). The result showedthat the students' description of important caring behaviors has many similarities. However, theresult also showed that there were significant differences between the student-groups where thestudents at the beginning of their education rated several caring behavior as significant moreimportant than the students in the end of their education.

The purpose of this study is to investigate the content and work processes regarding the values written in the curriculum for Swedish high schools and compare it with theories regarding the individualized society and political moralism. After the clarification of the content in the values of Swedish high schools and the work processes that are supposed to give students fundamental understanding about them, I analyze and compere it to the theories that are presented in the study. The main questions of the study are the following: What kinds of values are found in the curriculum for Swedish high schools? In general, how do Swedish high schools work with the written values when focus have gone from education and learning to instrumental knowledge, results, abilities and flexibility?The result showed that the content and work processes regarding the values in Swedish high schools are purely instrumental and moralistic. Due to the fact, that the individualized society and the neoliberal ideology do not require reflection and real understanding regarding the values.
