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 of this study is to investigate the notion of pupil influence in English teaching at level 1 and 2 at High-School level. The study focuses on how the students and teachers experience the possibility of influence in their English classes. Empirical data has been collected through questionnaires from two classes at year 1 and two classes at year 2 in English. The study also includes interviews from four teachers and four students. The study is both qualitative and quantitative.

Långvarig stress ökar risk för ohälsa och sjukfrånvaro, med negativa konsekvenser för individ, organisation och samhälle. En preventiv metod för stresshantering är Acceptance and Commitment Training (ACT). Syftet var att med en randomiserad, kontrollerad studie undersöka huruvida en kortvarig ACT-intervention påverkar stress och generell psykisk hälsa hos socialsekreterare inom Stockholms stad (n=106). Bortfall hanterades med intent-to-treat-analys. Vid förmätning rapporterade två tredjedelar av deltagarna hög stressnivå (PSS?25).

Sickness absence is a measure of health and is therefore an important issue. To get a complete picture it´s important to also include in the discussion sickness presenteeism, working while ill, and voluntary absence, staying at home without illness. Working conditions have been proven to play a role for the three aspects which is why this study aims to further investigate the connections between them. The method used was secondary processing on interview data collected from two home care teams, one having a low and the other a high sickness absence. The results showed that there were big differences concerning working conditions, where the group with the high sickness absence perceived more stress, less control and less support from colleagues and superiors.

The aim of this study was to investigate whether a dietary change, physical activity or a combination of both gave the best result when treating obesity, concerning weight loss and BMI. Excessive weight and obesity are today a big health-issue and it is estimated that 10 % of the men and 12 % of the women in Sweden have a BMI over 30, i.e. are suffering from obesity. The corresponding number for children is 3 %. No one can say for sure what causes obesity but there are many theories.

In this bachelor's thesis, we investigate the Swedish folk high school?s role in neoliberal society, which is analyzed through the lens of Norman Fairclough's critical discourse theory as well as Erving Goffman's theory of social deviants. The focus of our study has been participants in creative education, such as art, theater and creative writing. Our findings include that participants at folk high schools find great value in their education, both creatively and personally. They note that they have experienced a large amount of personal growth, regarding both openness towards others and higher confidence and their own abilities and identity.

The purpose with this study was to investigate how the behaviour and physiological parameters differ between high ranked and low ranked cows, and between cows in an automatic milking system verses conventional milking parlour. The study was carried out at the Kungsängen research Centre, Department of animal nutrition an management, Swedish University of Agriculture Sciences, Uppsala. Twelve cows, the six highest and the six lowest in social rank were selected from the automatic milking system for the experiment. Ten cows, the five highest and five lowest in social rank were selected from the conventional system. Blood samples were taken during milking and resting.

This is an examination report in physical education. It focuses on the relation between excercise and nutrition and how this relation works in an icehockeygymnasium in a midsized city in Sweden. The training ratio for the students are 11-12 times a week which indirectly means that the nutricion is very important to them so that they have the strength to manage both training and school. In this examination report you can read about how the food is composed and how many meals the students are offered through their education program. The persons that I´ve interviewed are the head coach, the president of the school restaurant and three students.The students have practise in the noon two times a week, on Tuesdays and Thursdays.

Bakgrund: Tidigare studier har visat att barn har sämre styrka i överkropp och bål samt är mindre fysiskt aktiva nu än tidigare, detta skulle kunna medför en ökad hälsorisk framförallt på längre sikt.Syfte: Att undersöka om ett pass med 4 min Tabata intervaller med stabiliserade övningar, varje skoldag under en 6 veckors period gav någon skillnad på de fysiska testerna och gav en ökad stabilitet och styrka hos barn i åldern 7-9 år.Design: Studien genomfördes som en interventionsstudie med en kvantitativ ansats.Metod: 42 barn varav 23 flickor och 19 pojkar i åldern 7-9 år deltog i studien som genomfördes på skoltid i klassrummen. Utöver studiegruppen användes 13 barn som kontrollgrupp de genomförde enbart de fysiska testerna före och efter studien.Resultat: En signifikant ökning av antalet push-up (P<0.05) och push-up (knä)(P<0.05) kunde påvisas efter studien.Konklusion: De fysiska tester som visade signifikanta förbättringar hade liknande övningar inkluderade i Tabatastudien..

The purpose of this study was to identify reading strategies used by high school students when reading textbooks and school-related material. Any differences in reading strategies between Biology and English were also of importance. A study sample of 62 students from three different high schools in Sweden participated in the study and were asked to fill out a survey questionnaire. Eight students from this sample were also interviewed. The findings of this study show that students use a number of different reading strategies of which metacognitive and sociocultural factors play a crucial part.

Abstract This examination work is about the role of physical activity for students with concentration difficulties. The purpose of this work is to describe educators experiences of how students with concentration difficulties are affected by physical and motor activity during school-time in primary school. In the work I assume from my questions that are: How do educators experience students with concentrations difficulties? Do educators think physical and motor training during school-time matter for the students learning processes? How? Do students with concentration difficulties have other possibilities than other students regarding physical and motor activity during school-time? I am using a qualitative interview method for answering my questions. The interviews are conducted in collaboration with three educators in a medium-sized Swedish F-6 school.
