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.

Objective: The aim of this study was to study the prevalence of depression among patients with arrhythmia, and to investigate if there was any gender difference in the study population regarding depression. Furthermore, differences considering depressive symptoms between patients with arrhythmia and the general population were to be investigated. Method: The self-rating scale MADRS-S was distributed during two weeks to 24 patients with arrhythmia. Twenty-one patients completed the study. Results: 28.5 % of the participants showed symptoms of some level of depression.

The purpose of this bachelor?s thesis is to examine how students at Högskolan i Borås experience the web-scale discovery service Summon, based on the theoretical model of ?The Five Dimensions of Usability?, defined by Whitney Quesenbery. The study aims to answer the following research questions: How do the students execute search assignments in the Summon interface? How intuitive and easy to navigate is the system from a user perspective? What are the students? opinions about Summon, regarding usability?Five students with varying information seeking skills are asked to perform search assignments during controlled observation, followed by semi-structured interviews. Our findings are presented in the context of previous research and show correspondence with the results of related studies.

The study shows how seven informants, all studying at a university in northern Sweden to become art teachers, perceive and relate to controversial contemporary art in the context of secondary school art education. The study is based on semi-structured interviews. The study contributes to a nuanced view of these informants opinions and thoughts regarding provocative contemporary art, in relation to the school's democratic values ??and founding mission. The seven informants' responses were compiled thematically linked to the study's purpose and issues to allow for comparisons and analysis.

Barn födda för tidigt (gestationsålder, GA < 37) löper ökad risk för kognitiva nedsättningar, emotionella problem och beteendeproblem. För att undersöka möjliga skillnader och samband beträffande kognitiv nivå och beteendeproblem jämfördes testresultat från Wechsler Intelligence Scale for Children (WISC-IV) och Child Behavior Checklist (CBCL) mellan för tidigt födda barn (PT) (n= 51, GA 22-34) och barn födda efter fullgången graviditet (FT) (n=57, GA 40 +/-2), i åldern 7-8 år. Alla barn var normalfungerande utan känd utvecklingsavvikelse och/eller hjärnskada. Resultaten visar att barn födda i GA 22-34 presterade signifikant sämre på verbalt (VFI) och perceptuellt funktionsindex (PFI) och erhöll en lägre helskaleintelligenskvot (HIK) jämfört med barn födda FT. En signifikant positiv korrelation uppvisades mellan GA och HIK men inte mellan GA och totala beteendeproblem.

The main purpose of the present study was to collect Swedishnorm data for the comprehension scale of the Reynell DevelopmentalLanguage Scales (RDLS III) for the ages of 4:6-4:11. According to theBritish manual the degree of difficulty increases gradually and therefore theorder of the sections was examined to see whether this was the case inSwedish. The study also examined the relationship between the test resultsand shared book reading. A total of 88 children and their caregiversparticipated in the study. The participants were recruited from preschools inGöteborg and Mölndal.

This essay examines the possibilities for the use of ICT for learning in the subject of history. By interviewing history teachers in upper secondary school about their experiences and thoughts regarding the subjects of learning, history and ICT, as well as the relations there between, based on Mishra and Koehlers TPACK model, I come to the conclusion that ICT may enhance learning in history. I also conclude that ICT may create new learning environments in history, where knowledge may or may not grow.The more unique ways of using ICT in history, compared to other school subjects, appears to be the possibility of using a variety of new sources, for example digitized primary sources from archives, that perhaps will motivate students, and make it possible to work from a con- structivistic point of view in history.Other unique possibilities are to satisfy the need of concretizing and visualizing the history being taught, by using a broad range of different media when presenting it. .

AbstractThis study is about describing the pre- internationalization phase and to studycompanies that are in this phase. We are trying to capture characteristics of decisionmakersin the pre- internationalization phase, to then compare the theoretical materialwith empirical material from case companies. Then in the final stages of the thesis, wewant to account for if we managed to answer our research questions. In the method, wegive a description of the approach selected in conjunction with the study. The study isqualitative and we used both primary and secondary data, with a deductive approach.The theory chapter will consider the most relevant theories that are related to the topic,which is internationalization, pre-internationalization, international entrepreneurship,and the psychology behind personalities, attitudes, and how these can affect theorganization's strategic decisions.

Quality is the main focus in management of all laboratories. Accurate results of the analyses are not only determined by the analytical procedure but also by preanalytical factors. In the total analytical process of clinical specimens, there are many possible preanalytical sources of error. Monetoring of temperature on test samples of the transport boxes is one way to reduce the mistakes in the preanalytical phase.In this study, four laboratories from primary health care were invited to participate. The temperature has been measured on test samples of the transport boxes being delivered to the laboratory.In three cases the temperature remained within the limits, but in the fourth case the temperature varied more than the allowed interval.

Due to an increasing amount of people being put on a sick-list the issue of work health has come to receive a lot more attention. To confront the problem, different varieties of keep-fit measures have been launched in the workplace. A prime example of such a measure can be found at Centralsjukhuset Kristianstad, which this survey is investigating. The primary goal of this study is to investigate the use of the Keep-fit measures program and to identify what motivates the employees to utilize this program. Further we would like to investigate if the program, through motivation and learning, generates improvement and retention of the individuals? health.

Who would not like a profit of more then 95 % in a day? Investors in Sweden had thatopportunity, if they had bought a certain stock on the primary market and sold it on the firsttradable day at the Stock Exchange. Most of that profit fell into the hands of institutionalinvestors. The reason for this extraordinary profit was the underpricing of that specific stockduring its initial public offering (IPO).Our report aims to analyze the relationship between offer price, underpricing and theownership structure of stocks. Our investigation is based on all IPO?s on the Stockholm stockexchange during the years between 2000 and 2005.

The study aims to give a description of the conditions in which matters is prepared withinSwedish Government`s offices, to describe the adaptive capacity in the agency`s internalprocesses by investigating the experiences of some civil servants restricted to the Ministry ofEnterprise and the Ministry of Environment in their work with the EU Maritime Policy GreenPaper. The results have been analyzed against the basis of eight identified criteria of buildingadaptive capacity in socially dominated systems. The criteria are comprised of both individualand organizational abilities. Only two of them were fully met; the criteria about diversity inexperiences and knowledge and the criteria about information and how the information hasbeen applied. However, the process has traces of all the identified criteria.

In this essay I examine the causal relationship between confidence in institutions and growth in Sweden 1989-2002. By examining the causal relationship between these two variables, valuable indicators of the causal relationship between trust and growth can be obtained. The institutions which are used in this essay are chosen according to the theory on institutions for public administration building trust and social capital. The chosen institutions are primary schooling, the police and medical service. A Granger causality model is used to measure the causal relation and the results from the tests show that there is no causal relationship between growth and confidence in institutions.
