Trollhättans befolkningsmål: 70 000 invånare år 2030. En analys ur ett byggentreprenadföretags perspektiv

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.

Teknisk Analys : Hur påverkar marknadsförhållanden valet av investeringsstrategi?

Idag äger drygt 7 miljoner svenskar någon typ av värdepapper. Dessa handlas av två typer av investerare, den aktiva och den passiva. Den aktiva investeraren köper och säljer sina värdepapper mer frekvent för att dra nytta av dess upp och nedgångar, jämfört med den passiva investeraren som köper värdepappret på lång sikt.En aktiv investerare analyserar ständigt marknaden och dess utveckling, försöker utläsa historiska mönster för att förutspå hur framtiden kommer att utveckla sig. Att studera historiskt kursdata för att förutspå framtida mönster kallas teknisk analys . Två vanligt förekommande analysmetoder inom teknisk analys är glidande medelvärde och Relative Strength Index.

Vinterträdgårdar ur ett byggperspektiv : En undersökning om byggandet av vinterträdgårdar

The purpose of this of this essay is to explore the construction of a conservatory that is livable allyear around. When you build a conservatory there are several factors that need to be regardedthat usually are of no importance when you build a regular conservatory. The glassed facadeneeds to have a very good U-value and all the parts of the facade need to be isolated and theconstruction needs to prevent thermal bridges.In this essay we will start by looking at the shape of the conservatory. Due to the façade consistsof glass the conservatory will need to have a good ratio between the area and the façade so thatthe heat losses will be at a minimum. However, due to the fact that one of the sides of the façadeis connected to the warm house, you quickly realize that the shape of the conservatory is of noimportance.There are two common ways to build a foundation for a conservatory, a molded concretefoundation and isolated wooden beams.

Att bilda till frihet : En studie av folkbildningens ideologiska påverkan och utveckling 1990-2012

During the last two decades, the elementary, - secondary-, and upper secondary schools of especially Europe and USA have gone through a change. From being formed in the post war time and, in Europe, very influenced by the ideas of social democracy, the school today has more and more come under the influences of neo liberalism, entrepreneurship and the political and economical situations during the late 1980´s.This undergraduate work brings up the changed discourses of education and knowledge in relation to the traditional free school system for adults in Sweden, the popular education, and especially in relation to folk high schools (folkhögskolor). By using, first and foremost, the idea of Norman Faircloughs critical discourse analysis (CDA) the rules and documents concerning the folk high schools are analyzed. The purpose of the paper is to identify and recognize the movement in the discourse to reach an understanding about the political situation for folk high schools in Sweden. In the end you can see that it is possible to define a similar development in discourse surrounding the popular education, as has been in the case with the elementary, - secondary-, and upper secondary schools..

Fysisk status hos pojkar med typ 1 diabetes

AimThe aim of this study was to survey the physical fitness in boys with type 1 diabetes (IDDM). The results were compared to a control group with healthy boys that have preformed the same tests in other studies. Our questions were:1. How does BMI relate between IDDM-children and healthy peers?2.

New public management och den svenska gymnasieskolan : En ideologikritisk analys av Gy11-reformen kopplat till organisationskonceptet new public management

The purpose of this ideology critical study is to investigate the hidden content in the reform Gy11 and compare it with the concept new public management. After the clarification of the hidden content, we compare the structure of the organization in Swedish high schools with the structure in public sector called new public management. The main questions of this study are the following: Is it possible to see the foundation of new public management in the Swedish high schools when it comes to the views of knowledge and the formation of goals? Which similarities can we find when we look at the organization new public management and the Swedish high school?The result showed many similarities, both regarding the views of knowledge and the formations of goals. The structure of new public management has been largely implemented in the Swedish high schools and the schools now focus more on instrumental knowledge rather than universal knowledge based on understanding.This is not surprising due to the social progress.

Hälsa i ämnet Idrott och hälsa : En kvalitativ studie om idrottslärares perspektiv på och arbetet med hälsa i ämnet Idrott och hälsa.

The aim of this qualitative study was to study high school PE teachers´ experience of health in high school and how they work with health in their physical education. This was examined by interviewing five high PE school teachers. The results show that all teachers were in the category humanistic approach. They saw health as more than only absence of sickness. The methods for using health in their physical education were divided into three different categories; physical health, improve the individual and theoretical health.

Vad är det som gör att killar väljer teknik och tjejer frisör

The properties of this material has been studied and it was found that there is very little difference in what affect students in there choice of school, studies and career. Boys who choose hairdressing and styling differ more than girls who choose a career in technics. This is a surprising result which we didn´t expect. In researching background material we learned that it should differ more in perspective of gender. We have compiled the material around young people's choices to high school.

Påverkan på muskeluppbyggnad i samband med alkoholintag efter träning

Sahlgrenska AcademyAt University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstract:Titel: Effect on muscle building associated with alcohol intake after exerciseAuthor: Frida Bond och Linnea DanielssonSupervisor: Frode SlindeExamminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDatum: May 26, 2014Background: Drinking alcohol is often used as something to spice up weekdays as well as more festive occasions. The reverse aspect of alcohol consumption is that the body sees alcohol as toxic and therefore the basis for a number of diseases. Exercise and physical activity have been proven to be good for several welfare diseases such as diabetes and cardiovascular disease. Among people in general, opinion is divided as to how exercise combined with alcohol affects muscle building, but what do science say? Objective: The purpose of this review article is to analyze and summarize the existing scientific data about how the structure of muscles is affected in relation to alcohol intake after exercise.

Husproduktion, kritiska skeden i produktion

As a newly graduated student in construction you rarely have as much knowledge as you wish you had. It is a complicated line of business that requires knowledge and understanding of both technical solutions and interaction between actors. It is impossible to be fully learned and with that much unknown it can be hard to know where to start. This report is one step in the right direction. It contains a planning that contains construction and installations for a one level house in Kiruna with its different choices motivated.
