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.
En kvalitativ och kvalitativ studie om hur pedagoger upplever och resonerar om ljudnivån i förskolan
Studien belyste pedagogers upplevelser av ljudmiljön i förskolan samt hur de säger sig planera och organisera den pedagogiska verksamheten för att främja en god ljudmiljö. Studien var angelägen på det vis att det är viktigt att pedagoger inkluderar ljudmiljön i verksamheten och ser till att den inte utgör ett hinder för barns lärande och utveckling. En medvetenhet om det pedagogiska uppdraget är en viktig del, så att barn och pedagoger inte exponeras för skadligt ljud mer än nödvändigt. Förskolan ska erbjuda barnen en verksamhet där barn och pedagoger trivs och mår bra tillsammans. Därför är det betydelsefullt att arbetet kring ljudmiljön hålls levande.

EMC problematik och el-kvalitet i elkraftnät
The dissertation deals with an account of actual problem, which can arise within EMC and power quality. The cause of power interruption and what can be done to minimise the power interruption is discussed. It also includes a definition of planning levels and which factors one needs to have control over to carry out a possible planning strategy and how the local distributions net could be more secure. The electrical net could be secure but no system can be free from interruption.The dissertation examines two distribution transformers: GLA40T1 (Glansås) and T399 in Tranås Energy which don?t have regulators.
Aggressivt utagerande: Betydelsen av samtidig förekomst av callous-unemotional traits och impulsivitet
Abstract The importance of the co-occurrence of callous-unemotional traits and impulsivity concerning aggressive acts was examined by a survey. The participants consisted of 1478 Swedish youth. Three groups with extreme scores on callous-unemotional traits and impulsivity was identified. The group scored high on both was more prone to show higher levels of aggressive and conduct problems behavior compare to the other groups. The aggressive and conduct problem behavior was shown at higher level in all examine variables. This study highlight that impulsivity can identify extreme aggressive individuals, without taking HIA (Hyperactivity, Impulsivity and Attention) problem as a entirety, to account, if shown with callous-unemotional traits. Keywords: Callous-unemotional traits, impulsivity, aggressive, conduct problem, youth, co-occurrence..

Sociala omsorgsassistenter : de "nya" omsorgsgivarna i en omsorgsförvaltnings "paradigmskifte"
Purpose: The primary aim of the study was to analyse and discuss how employees with a secondary nursing education describe their occupational character whilst working as well as the conditions for caring acts in a changing progress towards professionalism.Questions: What are the conditions to provide a high standard of care in this changing progress? What influence does it have on the occupational character ?Method: Critical case study and focus groupsConclusion: One of the central findings of the field study was the identification of two occupational identities; traditional and pedagogical orientated. These two occupational character traits are connected with different types of occupational competence and demands different theoretical knowledge. They also have different regards concerning the new title; social omsorgsassistent. A conclusion of the study is that a professional project of a non-specific nature is unable to stress the different levels of knowledge and competence that occupational identities have when one seeking professionalism..
