Brytspänningen är den spänning som uppkommer när överkopplingsmotståndet i lindningskopplaren lämnar sitt föregående läge vid omkoppling. Storleken på brytspänningen i lindningskopplaren beror på hur stor läckinduktansen är. Är den inte känd så kan brytspänningen istället beräknas med hjälp av FEM-programmet ACE (internt ABB-program) i samband med Mathcad. I ACE beräknas först reaktanserna i p.u-enheter mellan lindningarna och hur stora de är beror på lindningslayouten. Det är tidskrävande att använda ACE och Mathcad och uppgiften är att utreda de parametrar som påverkar storleken på brytspänningen samt att ta fram en förenklad beräkning av densamma.Genom simulering i ACE av en mängd olika lindningslayouter visar det sig snart att det är alltför många parametrar som påverkar reaktanserna.

The purpose of this study is to better understand patients suffering from psychotic illness along with their family members, and to identify treatment factors that have been helpful for these patients and their families by investigating how their relationships have been affected by treatment. In this way, treatment methods can be put in a theoretical context, treatment efforts can be clearer, and the therapist can develop professionally.The research method used is a semistruktureted interview conducted with tree patients and their families. One conclusion one can draw in the successful treatment with psychotic patients is strongly based on the therapist?s ability to build a safe and secure treatment alliance with both the patient and his family members. Meeting with patients in situations outside of the therapy room have been of great importance for the therapeutic process.Important themes for recovery that come forth during the interviews with the patients are the quality of the therapy session as healing factor.

The present climate discussion has made energy efficiency an interesting topic. Saving energy does not only help the climate but also saves money for the energy consumer. The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two milk farms, one with voluntary milking system, VMS, and the other with conventional milking system was used to measure interesting temperatures and electricity consumptions. The numbers were used both to do theoretical calculations and to construct a SIMULINK model. To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using a reference farm with different combinations of heat recovery and pre cooling. The farm was assumed to keep a dwelling house with the annual heat consumption 18165 kWh.

The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.

The workplace is for many associated with joy and commitment, for others it is associated with fatigue, inadequacy and cynicism that is explained as the three dimensions of burnout. A general view of burnout is that it is an individual problem that many companies ignore, because a preventive task does not generate immediate profits. This has been a growing problem for years. Burnout costs not only money but also time and knowledge. Unfortunately, the popular belief is that "If it ain?t broke, don?t fix it." Organizations that think this way are sacrificing future benefits for short-term gains.

Det övergripande syftet med arbetet är att undersöka och studera ett läsinlärnings projekt med fokusering på arbetet med storböcker. Med arbetet vill jag få reda på orsaken till att man har startat ett kommunomfattande läsinlärningsprojekt och vad läsinlärningsprojektet innehåller. Syftet är vidare att ta reda på vad storböcker är för något och hur man arbetar med dem. Genom arbetet vill jag hitta ett sätt som både inspirerar mig som lärare och mina kommande elever till att lära sig läsa. Arbetet inleds med en litteraturgenomgång där läsaren får bekanta sig med vad läsning är och med olika begrepp som nämns i resultatdelen.

Confusion can be a life threatening condition that is often missed by the nurses, thus it occurs in the same range as pain, fever or infections. Aim: The aim of this study was to describe the phenomenon of confusion among elderly patients, in order to establish a wider understanding of the patient's nursing needs. Method: Literature study based on scientific material. Results: The result showed the patient's ability to recollect and reconstruct episodes of confusion. During the confusion the stories contained a wide variety of experiences, such as threat, fear, suspicion, chaos and order, unreal experiences, a need to escape and a bad sleep.

Bakgrund och problemformulering: Prevalens av typ 2 diabetes ökar dramatiskt i olika länder och är speciellt kopplad till ohälsosamt beteende och felaktig livsstil. Diabetes kan leda till utveckling av en rad olika sjukdomar såsom hjärt- och kärlsjukdomar, nedsatt syn eller blindhet och amputation. P.g.a. allvarligakomplikationer och ökad dödlighet bland dessa patienter krävs evidensbaserade vårdinsatser och effektiv rådgivning. Distriktssköterskan har möjlighet att verka hälsofrämjande.

Background: Patients postoperative pain is often underestimated. Untreated or undertreated pain decreases the chance of optimal recovery after surgery. Pain assessment is an important factor of efficient pain relief. Aim: The aim of the literature study was to describe factors of importance for nurses´ assessment of postoperative pain in patients. Method: A literature study was done where qualitative and one quantitative article was reviewed.

The aim of this essay is to investigate what is burnout and how women who are affected by it manage their condition. Furthermore, we have investigated stigma and whether or not those affected by burnout are in turn stigmatised.A qualitative approach has been used to achieve our aims with this project. To support our analysis we have interviewed ten women who all have been diagnosed with fatigue syndrome along with studying relevant literature. The main theories used in this investigation are the symbolic interaktionism by G.H Mead, the term stigma by Erving Goffman and different theories on coping.The results show that the majority of women in the study had suffered from burnout due to work related stress and changes in their working environment. How they coped with and recovered from the condition depended on their own activity and how it related to their own support system.

Da? konsumenter idag a?r mer bena?gna att pa?tala brister i reklam, a?r det av intresse fo?r fo?retaget bakom den aktuella reklamen att ha?va missno?jet samt att skapa en la?ngsiktig lo?sning som fo?rebygger att missno?je a?terkommer. Syftet med denna uppsats a?r att redogo?ra fo?r hur fo?retag, med Top Toy som exempel, kan arbeta fo?r att mildra och ha?va det missno?je som ha?rro?r fra?n reklamkampanjer, samt hur fo?retag kan arbeta fo?r att la?ra sig av denna process. Detta underso?ks genom en fallstudie av leksaksfo?retaget Top Toy, som under en fyraa?rsperiod mottog klagoma?l pa? sina ko?nsstereotypa leksakskataloger och successivt arbetade fo?r att na? en lo?sning som kunde eliminera missno?jet.

Pet rabbits are increasing in popularity and the owners want the same treatment for them as they would want for a dog or a cat. However, the knowledge among clinical staff about these small animals is not always up to date. The aim of this paper is to highlight the needs of the pet rabbit and how these can be met regarding veterinary nursing. Pet rabbits are different from dogs and cats in several ways and their needs as patients differ as well. Rabbits are herbivorous prey animals. To avoid predators, they are very reluctant to show any sign of weakness for as long as they can.

Bakgrund: Diabetes mellitus typ II är en ökande folkhälsosjukdom där cirka fyra procent av Sveriges befolkning beräknas ha sjukdomen. Diabetes mellitus typ II är en kronisk sjukdom som kan leda till svåra komplikationer. Därmed är det viktigt att personer med sjukdomen får god information om egenvård för att själva kunna minska riskerna för att utveckla komplikationer. Inom diabetesegenvården är det viktigt med fysisk aktivitet, en god glukoskontroll, god fotvård samt en bra kost. En persons upplevelse är aldrig densamma som någon annan person i samma sist.
