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.

This report was performed in order to evaluate a new technological measure and focuses generally on a heat pump system to a HWC-washing machine. The client is Asko Appliances AB, a company well known for its environmentally friendly products. The goal of this study was to improve the energy efficiency of a washing machine by combining a heat pump device to the heater of the wash water, in order to reduce the energy consumed for heating the water. Besides reducing the energy consumption in heating the water, the washing machine was required to meet low noise and short operating time specifications. For that purpose, nine trials in three test series have been carried out.

This report is the final step in the Bachelor of Science program in Building Construction Engineering, Department of Engineering Sciences, Uppsala University.The purpose of this study is to highlight the difficulties and possibilities that could involve the introduction of new energy efficient technologies and changing work around this technology. This study focuses on energy use at a construction site or other temporary workplace where so-called portacabins are in place to address the need for temporary facilities.The method for obtaining knowledge on the subject was mainly interviews with site managers working in Svevia AB's various activities. In conjunction with the interviews I visited construction sites and portacabins if it was possible.My most important suggestion to Svevia AB concerns a better organization in order to make poratacabins more efficient on energy and costs. The company should also evaluate and monitor the energy efficient portacabins that are in operation.Expected energy savings of new technology may not materialize if there are gaps in information, education, technical services and technical maintenance. It is very important to utilize the experiences of new technology.

In the current study, the aim was to investigate whether tail posture and motion can be an indicator of the emotional state of pigs and if the tail posture of the pig is affected by social breeding value (SBV), coping style and/or housing. Emotional state can be defined in two dimensions: valence and arousal. Two batches of 96 finishing pigs were studied in a one generation selection experiment with a 2x2 set up and were housed in a barren or straw bedded pen. In each pen, 6 pigs (3 male, 3 female) were housed. A back-test was done to determine the coping style of the pigs with two categories; high resister and low resister pigs.

Apotekssektorn omreglerades 2009 och Apoteket AB miste genom detta ensamrätten till att sälja läkemedel. En ny konkurrens har för Apoteket AB bidragit till en förändrad situation som inneburit att nya krav ställts både på företaget och på dess personal.Denna studie syftar till att undersöka Apoteket ABs verksamhet, efter omregleringen av apotekssektorn, med fokus på företagets personalstyrning. Undersökningen riktar sig mot hur företaget vill att deras anställda ska arbeta för att attrahera och behålla kunder. Vidare har ändamålet varit att ta reda på företagets tillvägagångsätt för att implementera detta arbetssätt i verksamheten, samt att ta reda på hur de kontrollerar att det nya arbetssättet bibehålls. För att undersöka detta har datamaterial från sju intervjuer, tre av Apoteket ABs årsredovisningar samt tjugo rekryteringsannonser analyserats.Studiens teoretiska utgångspunkt är Hochschilds (1983) teori om emotional labor, vilken handlar om hur serviceinriktade organisationer använder sig av medarbetares känslor och emotioner som en resurs.

In addition to all our soldiers and officers who do military services abroad there are a lot of people who are affected by their choice to contribute, namely their next of kin. This report deals only with those who are next of kin to those who perform service abroad. The purpose of this study is to investigate the relatives' need for emotional and social support as well as practical and economical support. The main question is What kind of practical/economical and emotional/social support do close relatives require when a relative does military service abroad? The method used in this paper is a qualitative research interview.

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.

Through qualitative interviews with five teachers from three schools, two public schools within the same school management and a Waldorf school, the purpose of this study is to find out teachers' views on the phenomenon of life skills in the lower classes in school. What is the subject, how do teachers work with life skills, and should it be seen as a separate subject or integrated in all school subjects?The results show that the definition of life skills is a term with many interpretations. Two concepts that can be seen as the common denominators in the educators' views on the subject, however is, social and emotional skills. This is something that educators believe develop self-awareness and empathy in children and sees that as important as learning other subjects.

With increasing energy prices and increased focus on the environment we saw the need for companies to get control over their energy use and their emission of carbon dioxid. An analysis tool that integrates both these areas is, with our knowledge, not available on the market today. Therefore, our project became to develop such a tool.By doing this degree project we would like to clarify that energy consumption and environmental impact are integrated. The less energy consumed by today?s society the smaller the environmental impact will be.

This thesis provides a good introduction to the American environmental certification system LEED, Leadership in Energy and Environmental Design, and trough compar-isons between Sweden and the United States an explanation to the systems design is given. The work is closely linked to a LEED Core & Shell project in Stockholm, Swe-den, where the goal is to reach the second highest rating in LEED - Gold.This thesis gives a broad description of the LEED system and a more profound study of the energy sector, Energy and Atmosphere. Here, for example, an analysis has been made of how the energy consumption of an imaginary building designed according to the requirements of the BBR (Swedish building code) performs in comparison to the Baseline building in LEED.The existing model of Borgarfjord 3, which served as a case study in this work, has al-so been modified to investigate the energy savings that could have been achieved by adding extra insulation to the building. A description of the problems, regarding how the Swedish district heating system (DES) is treated in LEED, is given as well as the suggested modifications. This is an issue that will be pursued during the process of shaping a new, international, version of LEED due to be launched 2012..

AbstractThe Municipality Council decided in 2010 to develop a comprehensive energy efficiency strategy with financial and methodological support from Energimyndigheten (The Swedish Energy Agency). The strategy should include 3 major parts: an inventory of the 2009 energy use defining the current situation, the 2014 and 2020 goals for energy use, and an action plan for goal achievements. According to Energimyndigheten, the strategy must include all municipal administration premises, vehicles, and all majority-owned companies (as Laholmshem, the municipal housing company).The report describes the inventory work in order to obtain the 2009 energy use and the sources of information used. The inventory values are used as the base year values for the 2014 and 2020 goals. The inventory showed that information about the vehicles is dispersed in the municipal administration and no clear structure exists with respect to mileage and fuels used.
