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.

Under de senaste åren har marknaden för svenskarnas olika sparandeformer förändrats. För bara några år sedan hade storbankerna oligopol på marknaden, med många trofasta kunder som varken ifrågasatte bankens avgifter eller rådgivning styrde de marknaden efter sina egna villkor. Nya aktörer har funnit en lucka in på marknaden som därmed har gått mot en allt friare konkurrens. Stark kritik har riktats mot bankernas höga avgifter och deras begränsade utbud. De nya aktörerna som bland annat består av Internetmäklare och fristående rådgivare erbjuder kunderna ett större utbud till en lägre avgift.

Studier har visat att frivilligt barnlösa individer stereotypt har betraktats vara olyckliga och otillfredsställda, något som inte har fått vetenskapligt stöd. Syftet med den här tvärsnittsstudien var att undersöka om det föreligger några skillnader i livskvalitet och livstillfredsställelse mellan frivilligt barnlösa personer och föräldrar i den svenska populationen. Forskningsfrågan undersöktes med en enkät som bestod av självskattningsskalorna QOLI (Quality Of Life Inventory) och SWLS (Satisfaction With Life Scale). 130 deltagare genomförde studien varav 54 är frivilligt barnlösa individer och 76 är föräldrar. Studien visade att det inte finns några signifikanta skillnader mellan grupperna med avseende på livskvalitet och livstillfredsställelse.

Syftet med föreliggande studie har varit att belysa hur ungdomar som kommer till Maria Ungdom svarar på frågor om sitt spelande, och om det skiljer sig åt mellan pojkar och flickor. Vi var intresserade av hur många pojkar respektive flickor som har spelproblem, samt om dessa eventuella spelproblem var kopplade till annan beroendeproblematik eller till föräldrars spelvanor och/eller missbruk. Studien baseras på tidigare forskning, samt delar av material från Maria Ungdoms undersökning om spelproblematik hos ungdomar, som genomfördes under år 2004. I undersökningen deltog 88 flickor och 69 pojkar. Resultatet visar att hälften av ungdomarna har någon gång spelat om pengar, och pojkar spenderar mer pengar på spel.

The aim of this study was to examine why young females develop self-harm behaviour. We also wanted to look at the differences between young females born in foreign countries and young females born in Sweden and investigate if there were any differences regarding the reasons for developing self-harm behaviour and the actual extent of the self-harm behaviour within the group. We used a qualitative method and performed interviews with nine professionals that work with young females with self-harm behaviour. To be able to analyse our qualitative interviews we used concepts such as modernity, anomie, safety and cultural differences in the bringing up of children. The results of this study shows that self-harm behaviour is a symptom of excessive anxiety, which can be caused by a number of reasons, such as childhood trauma or great demands in modern society.

Den, i olika forskningsartiklar, återkommande uppfattningen om att enperson som är autonomt orienterad är mer benägen till att utveckla enmotivation till personlig utveckling ledde till denna undersökning.Syftet med studien var att undersöka hur autonomi påverkar människortill motivation till personlig utveckling. Studien tar sin utgångspunkt iself-determination theory och dess underteori causality orientationstheory, med de tre orienteringarna kontrollerad, impersonell ochautonomi, vilka handlar om orsak till varför en person handlar på ettvisst sätt och effekten därav. De olika orienteringarna mättes med enenkät konstruerad efter general causality orientation scale ochmotivation till personlig utveckling mättes med egenkonstrueradefrågor. Enkäten lades ut på fyra olika sidor på Internet medförhoppning om att nå ett brett deltagande. Studien visade att denkontrollerade orienteringen var den av de tre orienteringarna sompåverkade människor i högst grad till motivation till personligutveckling.

The purpose of this master thesis is to investigate if the mobile library has a similar role as the public library. To study this further we intend to examine the value and function of the mobile library. Answers are sought to the following questions: Can the mobile library be seen as a public library in a smaller scale? How do the users experience the value and function of the mobile library? What does the library staff think of the value and function of the mobile library for the users? What would the consequences be if the service of the mobile libraries would not exist? The method used was qualitative interviews. The groups of respondents are mobile library users and library staff.

The question formulation for this work has been "is an ice-hockey audience influenced by music during time-outs in a game?". The method was to observe one period with Färjestads BK and Mora IK, but a recording was also made, together with a conversation with the arena DJ. From the recording, the audience reactions were graded from a given scale. The grades were compilated to a diagram that shows the audience reactions in relation to the time, from the first face-off to the final whistle.

Background: A common view about people with diagnosed psychosis is that they are socially withdrawn and that they neither cope nor want to engage in social relationships. Newly published specialist books on this subject also support this view.Aims: To unveil further dimensions of the phenomena by explorative analyzing consumers? own depictions about their ?social relationships".Method: The material is taken from a larger study that followed consumers regularly during a lapse of 3 years. Within this material 15 interviews from three respondents were chosen, a selection which gives maximal spreading concerning age, sex and background. The interviews where analyzed by methods based on Grounded Theory.Results: Three main dimensions were identified: supportive relationships, difficulties and social withdrawal.

Introduction: Breast pain, mastalgia, is a common problem for many women. The pain can cause so much concern that the woman seeks help in health care. The cause of concern is often that that the pain may be due to breast cancer. Women with mastalgia are referred for mammography to investigate the cause of the pain. Experience says that the mammography is mostly normal.Aim: The aim of the study was to get an overall picture of the results of the mammograms performed on Mammography SU / Sahlgrenska in 2011.
