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.

The aim for this study was to investigate if it is less stressful for cow and calves in loose housing systems when separation is made so they can see and touch each other (Physical Contact-PC) instead of just hearing each other (Hearing Contact-HC). The behavior of eight cow- calf pairs (n=4 pairs per treatment) on an ecological dairy farm with cubicle housing were studied for four hours directly after separation and four hours the day after separation. The first four cows that gave birth were used for treatment PC, and the following four cows that gave birth were used for treatment HC. The only selection criteria used was that both cow and calf were healthy. Separation took place 3-4 days after birth and the calves were put separately in two different pens while the mothers were let loose into the cubicle system.

Socialt stöd bidrar till mindre risk för yrkesrelaterad utbrändhet. Var tredje lärare uppvisar inom sina första arbetsår symptom på utbrändhet. Syftet med föreliggande studie var att undersöka samband mellan socialt stöd och utbrändhet hos grundskolelärare. Totalt deltog 71 respondenter i Stockholm via enkäter. Socialt stöd mättes via Berlin Social Support Scale och utbrändhet mättes med Shirom Melamed Burnout Measure.

The worsening of psychical health issues among young people has widely been discussed over the last few years. Research shows for example that 9% of girls at the age of 16-24 reported anxiety problems in 1989 while 16 years later, in 2005, the same number was 30%. The purpose of this essay was to study and analyze psychiatrists', psychologists' and counselors' view on the resilience and risk factors for youth depression (age 16-24). Beside this, our aim was to study their view on the influence of family environment on treatment and recovery. Data were collected with qualitative interviews with eight informants within the psychiatric care.

Very often we are likely to hear how important it is as adults to help small children and pupils out of bullying situations, both for the bullied one and the bully. What we often tend to forget is that bullying situations among adults are as common as the ones children put up with. The only difference is that the ones adults go through is a much more silent one, and the bullies often have a better strategy on how to beat down their victims slowly. Some of the cases also show that the bullying that is happening among adults is similar to the one between children. The risks in the bullying that occurs in the work environment are such as: bad self-esteem, doubting in their roles as professionals, anger, depression, anxiety and in some cases can be so dangerous that the suffered one eventually commits suicide.

Studier som berör ämnet hur fysisk aktivitet påverkar det psykiska välbefinnandet hos äldre är något som berör alla. Fysisk aktivitet har i tidigare forskning visat sig påverka båda den fysiska och psykiska hälsan positivt. Mycket forskning är gjord på området, dock är de äldre underrepresenterade som målgrupp inom området. Syftet med denna studie var att undersöka i vilken utsträckning fysisk aktivitet påverkar det psykiska välbefinnandet, med inriktning självkänsla och fysisk självuppfattning, hos äldre. Undersökningen innefattade en experimentell undersökningsmetod med en randominiserad, kontrollerad design.

Syftet med denna studie var att undersöka om det fanns skillnader i konfliktbenägenhet på arbetet beroende på syskonplacering och partnerstatus. Deltagarna var till största delen tågresenärer med en medelålder på 39 år. N= 174. Instrumentet bestod av en enkät med en standardiserad del, NEO-PI-R, som mätte personlighetsegenskapen agreeableness samt en nykonstruerad del som mätte arbetskonflikt. Skalan har fått namnet work-conflict scale (WCS).
