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.

Abstract This essay will present actual research around the concept of Post- Traumatic Stress Disorder, how it can reveal itself in school children and how it can influence young people?s learning ability and capacity to retain knowledge.The purpose is, above all, to clearly diagnose PTSD so that children with this complex of problems can receive good possibilities in learning and understanding.The question at hand is responded to by interviewees with an expertise on the subject and one ?story?, collectively with literary studies.The results illustrate that there can be neurological and biological, as well as social explanations for PTSD but it is seldom a permanent diagnosis. It is though something to take very seriously. PTSD can lead to severe psychobiological consequences, mostly by causing damage in one particular part of the brain, known as hippocampus. The hippocampus is essential in terms of memory and concentration.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

?Re:Regional? is a diploma work by Sanna Alm and Ylva Hedin, for the Master?s Programme in Spatial Planning presented at the Blekinge Institute of Technology, Karlskrona, Sweden. ?Greater Helsinki Vision 2050 ? International Ideas Competition? was the starting point of this study. The competition was launched the 15th of December 2006 and the closing date was the 31st of May.

Östersjöregionen är en av Europas snabbast växande regioner och Blekinge har ett strategiskt läge mitt i denna expansiva region. Studien behandlar Sydöstra Östersjöregionens utveckling och belyser de tre INTERREG-projekten Seagull, SEB Trans-Link och Baltic Gateway ur ett robusthetsperspektiv. En robusthetsanalys med hänsyn till tekniska, ekologiska och sociala aspekter görs med utgångspunkt från identifierade regionala riskfaktorer samt de effekter INTERREG-projekten förväntas få på Blekinge. Resultaten från analysen jämförs sedan med Blekingestrategin och slutligen presenteras föreslagna prioriteringar för att uppnå ett robustare Blekinge..

Bakgrund: MoDo Skog upplever idag att deras ekonomistyrning i allt för hög utsträckning fokuserar kostnader, framförallt kostnader som förknippas med avverkning samt transport av råvara. Som ett led i denna kostnads-fokusering har MoDo Skog en misstanke om att det förekommer suboptimeringar inom virkesflödesprocessen. Före-taget upplever dessutom att de är dåliga på att mäta och följa upp så kallade mjuka faktorer.Syfte: Vårt syfte med denna uppsats är att kartlägga en virkesflödesprocess och därefter undersökaförutsättningarna att utarbeta ett Balanced Scorecard med funktionella nyckeltal. Avgränsningar: Arbetet inom fallföretaget begränsas till att gälla virkesflödesprocessen från avverkning till dess att råvaran kommer till industrin på Iggesundsregionen. Vi beaktar endast de avverkningar som sker på fallföretagets eg-na marker.Genomförande: Studien har genomförts på fallföretagets region Iggesund.

Aim: The aim was to investigate and describe, how students on high school level in Kronoberg county self rated their health with relation to irritation, nervousness/anxiety insomnia and gender. An additional aim was to investigate if there are differences between students born in Sweden by Swedish parents, students born in Sweden by foreign-born parents and foreign-born students. Methods: A quantitative method was used to analyse data gathered from students (n=1936) on high school level in 2006. All statistical analyses were made with help of SPSS V-12. Finding: The findings showed that most of the students self rated their health as ?good?, however migrant students self rated their health as ?not so good? and they had more problems with insomnia. The overall findings showed gender differences. Particularly, foreign-born girls self rated their health as ?not so good? and reported more problems with insomnia. There was no divergence between the groups regarding irritation, nervousness/anxiety. Conclusion: School nurses and health workers must have deep knowledge about differences in gender, self- rated health and insomnia when they work with public health.

Denna uppsats har för avsikt att undersöka det negativa sambandet mellan arbetslöshet och tillväxt i svenska län. Sambandet vi använder oss av är den inom nationalekonomin välkända Okun?s lag. Denna lag kommer vi att applicera på Sveriges 21 län mellan åren 1986 till 2003. Vi förväntar oss att sambandet kommer att variera mellan länen.

The aim of this Master's thesis is to discuss and analyse co-operation between public and academic libraries. The political changes that were initiated during 2004 have come to alter the conditions for Swedish libraries. The Swedish library law was changed at the 1st of January 2005 and co-operation between libraries is now statuary even if there is no description of how the new mission is to be executed. At the same time an extensive report about the Royal Library and its role as the Swedish National Library was presented. This report also recommended an increased co-operation between different types of libraries.

The aim of this essay is to give the reader an idea of how the European agricultural policies have developed, in regard of sustainable development, since Sweden became a member in the union 1995. The main aspect that?s been investigated is the issues regarding sustainable development and how the issues regarding the ecological farming methods have been dealt with. My research questions are:- How has the European environment- and agricultural politics changed since Swedenjoined the union in 1995?- What consequences have the changes had for ecological farming?The answers to the stated questions are that there have been several treaties in the field of environmental development of the agricultural policy, starting with the Maastricht treaty and ends up with the European Action Plan for Organic Food and Farming.

Rotröta i träd medför stora årliga skador och därmed kostnader för det svenska skogsbru­ket. Siffror som brukar nämnas i sammanhanget är 500-1000 Mkr/år. Exempel på orsaker till dessa kostnader är nedklassning av virke, tillväxtförluster, ungskogsdöd, tidigarelagda avverkningar och ökade stormfällningar. Syftet med denna studie var att analysera förekomsten av rotröta hos gran, tall och björk fördelat på ett antal ståndorts-, bestånds- och trädvariabler. Resultaten redovisades för hela landet och uppdelat på regioner.

Glutathione (GSH) is a molecule that consists of three amino acids: glutamic acid, cysteine and glycine. GSH has several important functions: to protect cells from free radicals, reactive oxygen species and oxidative stress. GSH exists in a reduced form, GSH, and in an oxidized dimeric form, glutationdisulfid, GSSG. The enzymes glutathionereductase (GR) catalyses the reduction of GSSG back to GSH. Nicotinamide adenine dinucleotide phosphate (NADPH) is required as a coenzyme in the reaction.
