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 essay analyses the European Food Safety Authority's (EFSA) legitimacy. Theories on input- and output legitimacy are used in the examination. After analysing stakeholder representation, forum for deliberation, transparency, independence, and information sharing, input legitimacy in EFSA is assessed to be high. Output legitimacy was examined through the authority's outcome effectiveness, which was divided into compliance and effectiveness. Since food safety is an immense area, two important parts were chosen for the analysis of output legitimacy; transmissible/bovine spongiform encephalopathy (TSE/BSE) and genetically modified organisms (GMO).

Using leaching test is a way to get a picture of pollutants retention and leaching in a risk assessment on contaminated land. There are several different types of standardised leaching tests today, where the natural leaching processes are speeded up to make it possible to predict the leaching of pollutants. These leaching tests have been developed for waste and there are no specific guidelines on how to judge the results from the tests, when making a risk assessment on contaminated land. This work is an investigation on how to use leaching test in this type of risk assessments. The strengths and weaknesses of the different types of tests are discussed. Depending on what type of information you want from your leaching test, different types of tests are suitable.

The purpose of this paper was to investigate how teachers work to lead and motivate high-performing students, and how these students were defined. The method used was qualitative, more specifically an interview, which was then analyzed with a thematic analysis. Six teachers participated in the survey, and what emerged was that high-performing students were often ambitious, structured and social students. High performing students were also characterized by the fact that they needed challenges, attention and positive feedback on their performances, otherwise they ran a risk of not performing. Structure was also important for the teachers themselves, that they had a goal when teaching and a way of achieving that goal.

Small business enterprises have escalated in Sweden during the last decade. However, new established companies are struggling to maintain their selves during the startup process and according to a survey from Tillväxtanalys, only 68 % of startup companies from 2008 were still active three years later. One of the main reasons is lack of capital and the most common approach to finance companies is to apply for a bank loan. In other words, commercial banks are of great importance for new businesses. Although, the problem arises when there is no previous history from the new businesses that the bank could base its credit assessment on.

Unaccompanied minors who are fleeing and being sent way from their countries of origin are nothing new. In 2011, 12 225 unaccompanied minors where registered in The European Union, none undocumented minors included. Most of the minors are coming from Afghanistan and Somalia. The aim of this essay is to investigate how The European Union?s migration policies are applied in reality and how United Nation?s Convention on the Right of Children are put in practice by the member states of The European Union and Norway.

Bakgrund: Undernäring hos äldre är vanligt förekommande. Orsakerna till undernäring är många och leder till ökad risk för komplikationer och minskad livskvalité. Enligt tidigare forskning ansågs kunskap om undernäring och åtgärder brista och en avsaknad av riktlinjer identifierades. Syfte: Syftet med intervjustudien var att undersöka sjuksköterskors upplevelse av nutritionsbedömningar, dess åtgärder samt uppföljning för vårdtagare i risk för undernäring på särskilt boende. Metod: Intervjustudie med sex sjuksköterskor i en kommun i sydvästra Sverige.

Sammanfattning.Bakgrund:Crush syndrome eller traumatisk rahbdomyolys är vanligt vid större naturkatastrofer som tex jordbävningar. Det kan också uppkomma när personer utsätts för tryck mot musklerna vid tex stroke, intoxikationer, byggnadsras, industriolyckor. Inom ambulanssjukvården i Sverige har vi inte någon behandlingsplan för detta tillstånd och därför kan det finnas en risk att dessa patienter inte får rätt omvårdnad.Syfte:Studiens syfte var att belysa ambulanssjuksköterskans omvårdnad vid risk för Crush syndrome.Metod:En litteraturstudie gjordes för att granska redan publicerat forskningsmaterial. Sökningarna gjordes i databaserna Cinahl och Pubmed. Fem artiklar inkluderades och innehållet analyserades med manifest innehållsanalys.Resultat:De patienter som riskerar att få Crush syndrom har följande symtom: skada på muskelmassa, förlängd kompression, komprimerad lokal cirkulation, puls >120 och onormal urinfärg.

Syftet med studien var att ta reda på om det går att predicera medarbetares livstillfredsställelse, psykosociala välmående och upplevd relation till närmaste chef utifrån chefers emotionsperception och emotionsreglering. Detta gjordes genom att 38 chefer utförde ett datorbaserat emotionsperceptionstest samt besvarade Emotional Regulation Questionaire. Deras närmaste medarbetare bestående av totalt 213 stycken fick sedan besvara en enkät bestående av delar från Satisfaction With Life Scale, SF-1 och QPS Nordic. Studiens huvudresultat visade att generaliserat kan resultatet från emotionsperceptionstestet och det självrapporterade användandet av omvärdering av känslor hos chefer förklarar 28 % av skattningarna på Satisfaction With Life Scale hos medarbetarna. Resultaten diskuteras i termer av att chefer skapar en positiv atmosfär på arbetsplatsen, identifierar sociala problem och löser konflikter effektivare när de är skickliga på emotionsperception och omvärderar sina känslor..

Avkastning och risk för en aktiefond styrs generellt av flera direkta och indirekta mekanismer, exempelvis relaterade till nationella makroekonomiska faktorer såsom ränteförändring och inflation. Utöver makroekonomiska faktorer finns indirekt mikroekonomisk påverkan, exempelvis relaterad till riskaversion, preferenser och irrationellt beteende hos individen. Därtill påverkas aktiefondernas avkastning och risk av övergripande internationella konjunkturcykler, inkluderande internationell makroekonomi.Studien som här presenteras fokuserar på att undersöka och kvantifiera hur bakgrund och egenskaper hos fondförvaltare systematiskt påverkar avkastning och riskexponering för 42 aktivt förvaltade svenska aktiefonder. Undersökningen inkluderar utbildningsnivå, kön, ålder och erfarenhet hos ansvarig fondförvaltare som förklarande variabler, samt avkastning, risk och riskjusterad avkastning som beroende variabler. Studien använder Sharpekvot, Treynorkvot och Jensens alpha som värderingskvoter för att åskådliggöra riskjusterad avkastning över tid.

Den här studien belyser hur revisorer i Sverige har påverkats av den globala finanskrisen. Inledningsvis presenteras tidigare skandaler och kriser som en bakgrund för studien, med anledning att upplysa läsaren om vilka konsekvenser det har fått för revisionsarbetet. Historiskt sett har yrket upprepade gånger haft motgångar som resulterat i hårdare krav och nya arbetsprocesser för revisorerna, där man gång på gång tvingats upprätthålla sitt förtroende och professionella status för allmänheten. Ämnet finner vi intressant eftersom det är under krissituationer som yrket prövas på allvar. För den här studien har vi valt en kvantitativ ansats som har baserats på en enkätundersökning.

This report describes a final thesis done during the spring of 2008 as part of the bachelor degree in computer engineering degree at the School of Engineering in Jönköping.The client is working in the consulting business and is involved in, amongst others, work regarding information security. Within this field they perform so called Threat, Risk and Vulnerability assessments. Today these assessments are done by a predefined method, but many details are controlled by the person documenting the project. A wish was made that the implementation was standardized, it should also ease the task of estimating the need for time and money. The solution for this seems to be a software tool.

Africa is expected to go through a rapid urbanization over the next four decades and the demand for food is increasing in the rapidly growing urban and peri-urban (UPU) areas. Keeping livestock in urban areas is in particular associated with health hazards. This is due to close interaction between humans and animals, and it has been shown that zoonotic diseases are increasing in urban areas. The benefits of urban and peri-urban agriculture (UPA) are related to improved food security, in particular among low-income groups. Apart from the negative public health impact of zoonotic diseases, animal disease could have a devastating impact on the economy and food security of many households in these areas. In the present study, three important endemic diseases, including brucellosis, salmonellosis and Bovine viral diarrhea (BVD), were analyzed in regard to seroprevalence and risk factors.
