This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.

This reportcommunicates the processes and results of my degree work in industrial design at candidate level at Umeå Institute of Design.During my degree work I had a cooperation with Svenska Jägareförbundet (Swedish Hunters Assosiation).The aim for my project has been to explore how I could make hunting a safer hobby and undertaking. Every year people get seriously injured and in average 2 people a year dies  due to hunting accidents. My goal is to identify problems within the hunters communication and approach. Through a creative design process I will find a valid  nd realistic solution to these problems. My project will be presented as a conceptual solution  hat will be based on currently existing technology.

Problem: What are the characteristics of Polykemi?s management control system and how is it affected by growth? Purpose: To describe and analyse the management control system of a medium-sized family-owned company from the perspective of Simons? Levers of control. Research design: An abductive, interview-based case study of Polykemi AB. Conclusion: Polykemi?s management control system is primarily a traditional one which is rather strong in terms of Levers of control.

I en delstudie till IDA-projektet har 185 kvinnor i 40-årsåldern skattat sin stress med PSS (Perceived Stress Scale) och genomfört fyra episodiska minnestest. Ett omvänt U-format samband med PSS som oberoende faktor och prestation i de olika minnestesterna som beroende faktor har prövats. Ett linjärt samband har sökts post hoc. Både explicit och implicit minnesprestation har mätts, liksom primär- och sekundärminnesprestation. Hög- och lågutbildade deltagare analyserades separat.

Socialt stöd bidrar till mindre risk för yrkesrelaterad utbrändhet. Var tredje lärare uppvisar inom sina första arbetsår symptom på utbrändhet. Syftet med föreliggande studie var att undersöka samband mellan socialt stöd och utbrändhet hos grundskolelärare. Totalt deltog 71 respondenter i Stockholm via enkäter. Socialt stöd mättes via Berlin Social Support Scale och utbrändhet mättes med Shirom Melamed Burnout Measure.

The prime aim of this thesis was to investigate whether high or low iodine intake during certain periods of life was, or was not a strong risk factor for the development of canine lymphocytic thyroiditis (CLT). And secondly, if a high or low selenium intake in a combination with high or low iodine intake also may have an influence on that risk factor. To investigate this, a dietary questionnaire was sent out to dog owners. The dogs were selected from an ongoing genetic study of CLT. The questions investigated brand and type of feed during different life stages (puppy, junior and adult) and also if there were any use of dietary supplements.

My goal with this Project was to create four pictures which de¬scribed four different emotions. The purpose of the project was that the pictures would be placed in a psychology department and they could use them as a starting point for a discussion about the patients? emotions. My personal purpose was that I wanted to create pictures in scale 1:1 in an analogue fashion, and try to learn more about how people see and feel about pictures. What kind of thoughts can a picture give you? Can I create a picture which can be used as a platform for a discussion? Can I make a picture which describes an emotion? The making of the pictures started with developing ideas and then I took photographs of my friend Joel, in different situations and moods, which I used as reference for my paintings.

Ultrasound is a diagnostic aid often overlooked by the veterinary practicioner who works with farm-animals. However, it?s use increases, particulary for breeders where ultrasound has long been used to evaluate ovaries and to diagnose pregnancy or disturbances in reproduction. There is much knowledge in how to examine ovaries and uterus by transrectal ultrasound, but when it comes to doing ultrasound of other organs in the abdomen the knowledge is more limited. Cows are very large animals, so it is not possible to examine everything inside the abdomen with ultrasound, simply because the ultrasound beam has a limited penetration. There is also lots of gas inside the gastro-intestinal tract of a cow, mainly in the large intestine and the rumen, and that makes it impossible to examine the organs behind the gas since the ultrasound waves are reflected when reaching the soft tissue-gas interface.

BackgroundResearch shows that the majority of patients feel anxiety before and during anesthesia. It has been shown in several studies that preoperative anxiety may cause adverse effects in the postoperative course. Nurse anesthetists have a key role in creating a safe environment and the opportunity to use different interventions to reduce the degree of anxiety.AimThe aim of the study was to examine which interventions may reduce anxiety in adult patients before and during both general, local and regional anesthesia.DesignSystematic literature review with a quantitative approach.ResultsSeveral studies indicate that gabapentin and pregabalin can reduce anxiety before and during anesthesia. The anxiety reducing effect appeared to be dose dependent. The naturopathic drugs Citrus aurantium blossom and Passiflora incarnata Linneaus were found to reduce anxiety before anesthesia.

Avsikten med detta arbete är att undersöka vilka känslor och tankar elever kan ha till djur, samt om de kan ändras när eleverna blir bekanta med djuren. Vi har valt att utföra en kvalitativ undersökning där vi kombinerar metoderna intervju och observation. Undersökningen genomfördes på tio elever i årskurs ett, där alla enskilt fick bekanta sig med en skalbagges alla livcykelstadier under ca 10 minuter. I början och slutet av varje intervju bad vi eleverna att berätta vad de kände och tänkte när de såg djuren, därefter grundade vi vår analys och tolkning av vårt material med hjälp av konstruktivismen. I vår undersökning såg vi att alla elever hade någon sorts känsla för och tanke om djuren, dock kunde det vara svårt att tyda känslorna eftersom vissa elever verbalt kunde uttrycka en känsla medan kroppsspråket visade en annan.

Depressionssjukdomar är vanligt förekommande och medför stor sjukdomsbörda. De psykologiska behandlingsmetoder som visat sig effektiva vid depression är bland annat kognitiv beteendeterapi (KBT) och beteendeaktivering. I denna studie undersöks effekterna av internetbaserad KBT med behandlarstöd vid mild till måttlig egentlig depression. Totalt 80 deltagare randomiserades till behandling respektive kontrollgrupp. De mätinstrument som användes i studien var självskattningsformulären Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Montgomery Åsberg Depression Rating Scale Self?assessment (MADRS?S) och Quality of Life Inventory (QOLI).

To this day, battery of women is a global problem. The aim of this paper is to examine this problem in the country that is considered to be one of the most equal countries in the world, namely Sweden. How big a problem is it, what is the social outlook of the victim and how does the Swedish justice system respond to this issue? These are some of the questions that will help to form an answer to the question if Sweden is a sanctuary for femalebatterers.Due to the resistance of implementing the entire penalty scale and the use of judicial methods, such as restraining orders and its effect on the women, the conclusion drawn from the answers is yes - Sweden is that sanctuary. The Swedish justice system is not tough enough when it comes to the abuse of women.
