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.
Lactobacillus reuteri som probiotisk terapi mot bakteriell vaginit hos avelsråttor :
Lactobacillus reuteri has been used as probiotics in piglet and chicken feedings as
well as in different diary products for humans. In this EEF-work I have shown that
L. reuteri can be an alternative for treatment of vaginitis in laboratory rats used for
breeding. In a breeding stock with 3000 animals some animals had a vaginal
infection with ??haemolytic streptococci group G.
Investerargrupper : En studie utifrån Wärneryds investerarmodell
Listed corporations achieve effectiveness through segmentation of investors. Categorization of like- minded investors diminishes goal incongruence. This thesis aim to examine an Investor models accuracy, provided by a Professor Emeritus in Economic Psychology in 2001. This model segments investors as active, passive, speculative and naive investors. This thesis has a demarcation to private investors on the Swedish stock market. It has a deductive and qualitative approach as the purpose is to study the Investor model.
Rökfri arbetstid? : En enkätstudie bland kommunanställda
Smoking is a health problem with a negative impact on virtually all body organs. Smoking can cause, for example, lung cancer, cancers in other organs and cardiovascular disease. There is also a social aspect of smoking. If individuals have many smokers in their environment, the risk to start smoking is increased, and for those who already smoke the chance of quitting will be less. Many municipalities today face smoke-free working to reduce smoking and passive smoking adverse effects.
DATORSTÖD FÖR ARBETE : KONSEKVENSER FÖR VAL AV AFFÄRSSYSTEM En studie av en service- och supportavdelning
This report is focusing on problems with introducing standard enterprise resource planning systems (ERP) in businesses. A study has been carried out on a service and support department at a Swedish heat metering company, SVM North Node. The study aims to help the company become a better customer in choice and customization of a new ERP system. We make a description of the department studied and the work carried out there, on the basis of learning, knowledge and cooperation. As a final point we present some ideas on how computer systems could support their work, hoping that this will result in them making adequate demands on a new ERP system..
Den ekonomiska lönsamheten för solvärme i Sverige
The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.
Energioptimering av Hemsö fästning med förslag på energieffektivare systemlösningar
The report is a master thesis about energy efficient measures for an underground facility Hemsö fortress.Several proposals are evaluated economically.Statistics of the electricity used and measurements of several heat pumps are analyzed to find energysavings potentials.The results indicate that several units of a dehumidification system are responsible for over 70 % of theyearly electricity cost. The air that is being dehumidified by these units can otherwise cause damage ofculturally important interior designs.The proposal with highest profit suggests an alternative method for dehumidification. The cooler in theair handling units in Hemsö fortress have capacity to dehumidify the air. However complementary fansneed to be installed to circulate humid air towards the air handling units. The solution can be implementedin three different locations within the facility.

Att bli förälder till ett prematurt barn - Litteraturstudie/Becoming a parent when a child is born premature - Literature review
Background: Almost every 20th child is borne premature in Sweden, before the parents are ready to care for a new family member. The parents need to cope with the stress and anxiety of having their newborn child in the neonatal ward and influenced by nursing care of neonatal staff grow their parental role.Purpose: The aim of this study was to illustrate experiences of parenthood within the care of premature at the neonatal ward.Method: A review where 18 articles between 2000 and 2005 were chosen and examined. The articles were analysed according to VIPS, which facilitates the practical use of the result.Result: The study reveals that parenthood is experienced as a time dependent process with three phases, primary, secondary and tertiary, where the parent?s needs and experiences changed character. The parents experienced that they developed from passive to active in the care of the premature child when the neonatal staff guided their participation, gave information/education and support.
Djursjukskötarens roll i rehabiliteringen av inneliggande patienter på hästsjukhus
Veterinary hospital care and advanced veterinary services are rapidly growing industries. As of January 1, 2010, veterinary nursing became a licensed vocation, the title of veterinary nurse became protected, and the act regulating competence among the professions of the veterinary field was extended. These changes, along with increased demands and expectations from owners, have given rise to greater demands on the staff's qualifications and have increased the need for well-educated staff with expertise in several different areas.
The aim of this study was to find out what the licensed veterinary nurse can do in terms of rehabilitation for the hospitalized equine patient suffering from orthopedic injury. This has been carried out through qualitative interviews with veterinary surgeons experienced in treating such patients, and also by reviewing the relevant literature.
