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 fertility of dairy cows is of great importance in order to maintain high production. The decline in fertility of dairy cows the latest decades can have several explanations. The large emphasis on high yielding cows and the negative genetic correlation between milk production and fertility traits could be one of the main factors for impaired fertility. To find heats and inseminate the cow at the right time is crucial to receive high conception rate. Delaval has, in corporation with FOSS, developed Herd Navigator which is a management program that measure four biological parameters in the milk; progesterone, betahydroxybutyrate, lactate dehydrogenase and urea.

The purpose of this study is to describe children?s life issues. What kind ofquestions they have aboutlife, their thoughts about life. Another purpose of this study is to see the differences in how children?s thoughts about life have changed through the years.

Intangible feelings of sorrow and grief, caused by events like separation, death, loss and trauma, all leave some kind of traces in us and they play an important role in our development. The individualistic society here in Sweden has shaped us to keep our feelings inside and at bay; since our childhood we have learnt that showing emotions like tears, sorrow and sadness are signs of weakness and can make others and yourself feel uncomfortable. With the starting point from my own experience and understanding of how we can deal and handle grief, I take a closer look on how jewelry, objects and rituals can be of importance in a grieving process and our lack of visual outer display of grief in today?s society. Through Sara Ahmeds theory I found a new possible way of understanding emotions and how they shape us.

Legionella can be prevented, the question is how. This report is a degree in construction engineering education at Chalmers University in Gothenburg. A comprehensive written publication for Legionella-safe plumbing installations is not available and therefore requested. The purpose of this report is to present preventative measures against Legionella bacteria growth in tap water and in other systems where Legionella bacteria are a potential problem. Technical solutions are presented including how different systems function and what their advantages and disadvantages are.

Every year big events takes place in different cities, one of the largest half marathons in the world is located in Gothenburg and is called GöteborgsVarvet. These kind of events rely on volunteers to even be able to manage the pressure from the arrangement. The purpose of the study was to investigate the motivation factors among volunteers? at GöteborgsVarvet 2012. This study is a part of a bigger project called EVINN that is an EU-financial researchproject which aims to develop arrangements.

Sedan den första skolsköterskan anställdes 1919 i Stockholm har skolsköterskorna bedrivit ett hälsofrämjande arbete på olika sätt. På senare år har hälsobesöket med elevhälsosamtalet hamnat i fokus och detta arbete syftar till att beskriva skolsköterskornas uppfattning om elevhälsosamtalet i grundskolan och på gymnasieskolan. En fokusgruppsintervju med fem skolsköterskor från Göteborg genomfördes och materialet bearbetades fenomenografiskt i en pilotstudie. Resultatet presenterades som tre huvudkategorier: ?Att använda en strategi?, ?Att skapa en relation? och ?Att utvärdera?.

This thesis examines and evaluates user boards in Swedish public schools from a democratic perspective. In order to evaluate whether the democratic values are fulfilled five different democratic ideals are selected to serve as a theoretical fundament. These ideals derive from the Swedish Government Official Reports that preceded the reform of user boards in schools, and are identified as the following: participation, dialogue, trust, democratic schooling and influence. The study is based on cases and involves two schools with user boards and two comparative schools with informal parental influence, so called school advisory boards. The study concludes that the main difference between the two types of parental influence is the level of formality.

Det har inte gått att undvika mångfald i dagens samhälle. Det talas och skrivs om det i media, det förekommer i jobbannonser och man pratar om det såväl som offentligt som privat. Ordet mångfald är ett ord som ofta dyker upp i denna uppsats. Det är ett ord som för många betyder ett positivt sådant. Även om mångfald är ett ord som betyder mycket och betyder olika för olika människor framkommer det i denna uppsats att mångfald innehåller två viktiga begrepp, nämligen etnicitet och kön.

This study focuses on the social medium Facebook. Its intention is to examine the contents of the Facebook statuses the Swedish parliament parties chose to publish in the final two weeks before the parliamentary elections in 2010. The key concepts used in the analysis are interactivity and multimodality. Aspects to be explored are interactivity of their status updates and how the parties used various multimodal objects. A comparison of the parties' usage also follows.

My purpose with this paper related to my questions was to find out how professionals preeschool teachers working on multilingualism. I also wanted to get answers on how pedagogues in the preeschool may promote multilingual children´s language development, the factors that promote multilingual children´s language development and the role parents have in the language development of multilingual children. I chose to do my study in the form of interviews with professional preeschool teachers and interviewees described including the need for more knowledge of pedagogues around multilingualism. My result based on theoretichal background and the study is that pedagogues should let the children´s all languages esemble together. A factor influencing the multilingual children´s language development is ambient attitudes to multilingualism.

The aim of this study was to examine young adult cannabis users? attitudes towards cannabis and their perception of the normalization of cannabis. The purpose was also to explore how their views of cannabis correspond with norms regarding cannabis. This study is based on interviews with five young adult cannabis users. The theoretical framework is based on Parker?s normalization thesis, Goffman?s notion of stigma, Becker?s definition of outsiders and the definition of social identity developed by Stone.

Arkitektkontoret Sweco Architects i Göteborg har tagit fram ett förslag för ett bostadsområde i Varberg, där Varbergs kommun var beställare. De föreslog att ett eget områdesförslag skulle tas fram i Revit Architecture utifrån de planbestämmelser som gäller i området. Som en fördjupning i detta arbete valdes att även studera arbetsprocessen i programmet samt hur denna process kan tidsoptimeras. Ett problem idag är att en sådan process kan vara tidskrävande och ineffektiv. Syftet med detta arbete var att finna idéer på hur processen kan effektiviseras och att utveckla kunskaperna om Revit.Som en inledning modellerades hur området ser ut idag i Revit utifrån en ritning skapad i AutoCAD.

This essay is a study of the Swedish author Amanda Svensson?s novel Hey Dolly (2008). The aim of the study is to investigate the conflict that occurs in the storytelling because of the untruthful narrator Dolly. Using the terms story and discourse, from a method of narratology by Maria Nikolajeva, the purpose is to analyze how the narrator manipulates the reader?s comprehension of what is real and not in the text.
