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.

Today is one of the goals with zoos to conserve endangered species and some animals may also become reintroduced. But behaviours can change in generations of captive animals because of environments that differ from the wild. Animals must then be prepared before being reintroduced and predator training enhances the animal?s chance to survive in the wild. When training animals to avoid predators it is often necessary to use frightening stimuli.

Föreliggande studie syftar till att genom en visuell innehållsanalys kartlägga gemensamma drag i 120 universitetslogotypers visuella utformning, samt undersöka samband mellan dessa karaktärsdrag och universitetens internationella rankningsposition.Med utgångspunkt från topprankningslistan Times Higher Education World University Rankings med 400 internationella universitet, indelade i fyra grupper i intervaller om 100 (d.v.s. rankningsposition 1?100, 101?200 etc.), valdes 30 universitet ut per grupp genom ett obundet slumpmässigt urval. Logotyperna för universiteten inhämtades främst från deras grafiska manualer.I studien presenteras förekomsten av generella drag med avseende på färg, typografi, typologi, detaljrikedom samt innehåll och form. Resultatet visade på tydliga gemensamma drag med i regel en till två dominerande karaktärsdrag per kategori.

Successful broiler production in hot climates requires knowledge of how birds are affected by heat stress. It is important with access to water and good ventilation to facilitate coping with the heat. It may be useful to reduce the consumption of feed during the hottest hours of the days, which together with a few hours of extra light available could improve both productivity and animal welfare. The vision in birds is superior to that of humans and most other mammals. Continuous light and light with low intensity can cause eye injuries, affect the eye development in young chicken negatively, as well as provide increased incidence of foot pad lesions. Access to light affects the production but also the welfare of birds.

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.

The purpose of this study was to investigate how the special education, for children with language impairment in preschool, was organised in a municipality in Sweden. The study was based on interviews and field studies as the primary research tools in qualitative and ethnographic method. The result showed that special education teachers were localised in different geographic areas of school and that there were preschools that lacked special educational expertise in language impairment. Literature and the importance of playing for language development were emphasised as well as the use of signs and visual aids as augmentative and alternative communication. In the preschool for children with language impairment, the teachers carried their knowledge into practical and pedagogical work.

Many species of amphibians are threatened both in Sweden and globally. The causes are many and a main factor is habitat alterations which often results in populations being isolated. Changes in the agricultural landscape have among other things resulted in small water bodies being filled and dried out and that has severely affected the Swedish amphibians. Swedish amphibians are depended upon small water bodies for their reproduction. Wetlands have been constructed to reduce the impacts of the eutrophication in the Laholm bay.

Empati kan beskrivas som en förmåga att veta vad en person känner och tänker. Denna studies huvudsyfte var att översätta C. Daniel Bat-sons empatiskala till svenska. Syftet var även att testa om det fanns skillnader vid perspektivtagande samt skillnader i empati när den and-re är snäll jämfört med elak. Deltagarna var 111 gymnasiestudenter som fick inta ett perspektiv, objektivt eller med inlevelse, och läsa en historia.

The effect of the salary system and age on the internal and external motivationThe purpose of the study was to examine how a fixed salary with commission and only a fixed salary, and age affect the internal and external work motivation of sellers. This was studied by a questionnaire and participants were sellers in the call center industry in Sweden. In total there were 112 sellers from nine different companies that responded to the survey. The respondents were divided into groups based on pay systems and age. The measuring instrument used was the Work Extrinsic and Intrinsic Motivation Scale which classifies the motivation of internal and external based on six subscales.

Syftet med denna studie var att undersöka om attityden till beröring bland Växjö studenter harnågot samband med deras självkänsla och kön. Tidigare forskning av Fromme et al (1989)visade att personer med dålig självkänsla tenderar att inte kommunicera genom beröring,vilket personer med god självkänsla gör. Enkätundersökningen genomfördes på 186 studentervid Växjö universitet där enkäten var baserad på frågeformulären Tennessee Self ConceptScale och The Touch Avoidance Questionarie. Resultatet visade ett starkt negativt sambandmellan beröringsundvikande och självkänsla. Det visade även att män tenderar att undvikaberöring med andra män mer än vad kvinnor undviker beröring med andra kvinnor.
