Förbrukningsreduktion : Ett alternativ till gasturbiner som snabb aktiv störningsreserv?
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.
Sjuksköterskors upplevelser av hot och våld i mötet med patienter inom ambulanssjukvård : - en intervjustudie
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.
Kinetikens tecken: en experimentell studie i samspelet mellan kroppens rörelser och dess försvarsmekanismer
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.
Närståendes delaktighet vid vård av äldre : -bemötande, tillgänglighet och information
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.
Parallel Import of Pharmaceuticals in the EU
Parallel import in the European Union is the perfectly legal activity under Art. 28-30 EC of buying goods in a low-price country in order to ship and sell them in a high-price country. The pharmaceutical market in Europe is subject to the subsidiartiy principle of Art. 5 EC and heavily characterised by national regulations that lead to significant price differentials between ? generally speaking ? Northern and Southern Europe.

Klimatförändringar och dess effekter på ogräsfloran i Sverige :
Land management for food production is a fundamental human activity and one of the greatest challenges of the 21st century will be to increase the global food to accommodate a world growing to 10 billion or more people, while undergoing climate change. The increasing temperature and the current and projected increase in concentrations of CO2 lead to concern over possible impacts on agricultural pests. This assay is summarizing the knowledge of weeds in a changing climate in Sweden. Global warming and other climatic changes will affect the growth, phenology, and geographical distribution of weeds. The climate change will also affect the weed composition indirect by causing changes in the agriculture.
Förtätning av Skövde Stadskärna
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.
Förvildade husdjur : möjligheter och hot
Feral animal populations are distributed over many parts of the world and are often seen as a problem. Since they are a threat against other species, destroy farmlands and can spread dis-eases, they are often referred to as pests. Artificial selection has contributed to loss of genetic diversity in our domesticated animals. Feral animal populations are affected by natural selec-tion, which allows them to adapt to the environment. Their ability to adapt is a reason to see them as pests but can also be seen as an asset.
Kunskapsläge och attityder till vildsvin (Sus scrofa) och dess förvaltning i Sverige
The wild boar (Sus scrofa) is since its recent establishment and increasing density a controversial species in Sweden. But the attitudes towards the wild boar are poorly documented so far. To improve this knowledge, a questionnaire was sent out to chosen people (n=400) connected to the management and/or land use activities.
The study got 162 replies (reply frequency 40,5%) and the results show varying attitude trends among organizations and individuals, with some aspects coherent within groups and some not. Farmers and their organization showed the most negative attitudes towards wild boars, which was expected due to the practical and economic problems they suffer from this species. People involved with forestry were more positive to wild boars, probably because the species does not affect forest growth etc severely, and may even promote plant establishment by the rooting.
?Developing a crucial business plan template targeted to Swedish Venture Capitalists?
Objective To study if the Swedish venture capitalists consider business plans in their screening process, and in such case, what aspects they evaluate in order to develop a targeted template for Swedish entrepreneurs. A secondary objective is to describe what other factors Swedish venture capitalists evaluate as a part of their assessment. Methodology The method, which has been used in order to test the objective, has been carried out through extensive literature and article studies, interviews, and distribution of a short and comprehensive questionnaire to a multiplicity of venture capitalists throughout Sweden. Conclusion Generally, the findings of this thesis suggest that a business plan should include elements such as a summary of important elements, a thorough market analysis, financial information, exit strategy, and the risks associated with the project. The empirical material also reveals that venture capitalists also evaluate factors such as ownership influence, the entrepreneur?s industry knowledge, product knowledge and the personal chemistry in their evaluation process.
Avancerade planeringssystem som beslutsstöd vid produktions- och distributionsplanering
Logistik och Supply Chain Management som koncept har fått en ökad uppmärksamhet de senaste åren. Ett föråldrat synsätt på organisationen som en samling vertikala enheter som fungerar autonomt byts ut mot en vision om en flödesorganisation där ett helhetsgrepp om verksamheten och djupare samarbeten med leverantörer och kunder står i fokus. Ökade krav på konkurrenskraft genom effektivisering ställer nya ökade krav på en fungerande planering och styrning av varuflöden och där kan så kallade avancerade planeringssystem (APS) fungera som ett stöd och hjälpmedel. APS för produktions- och distributionsplanering är fortfarande ett nytt och relativt oprövat beslutsstödssystem. De senaste åren har företag som utvecklar affärssystem även börjat utveckla och sälja så kallade APS-moduler som genom sofistikerade matematiska algoritmer och optimeringsfunktionalitet kan stödja styrning och planering av komplexa system såsom försörjningskedjor.
