The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Can an increased intake of omega-3 fatty acids have an effect on testosteronelevels in women with PCOS?Author: Ylva Dernbrant och Helene HagenborgSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundPolycystic ovary syndrome affects women of fertile age and consists of elevated testosterone levels and increased insulin resistance along with effects on ovulation and fertility. The elevated level of testosterone often leads to problem with acne and hirsutism, and it is also common with overweight and metabolic syndrome. The nutrition treatment has mainly consisted of energy restriction, together with exercise and drugs to reduce insulin resistance and consequently reduce androgen levels. However, an in-depth knowledge about how the components of our diet can affect further, is lacking.Omega-3-fatty acids can affect insulin resistance and testosterone levels within other groups but today knowledge is lacking if these findings can be transferred to women with PCOS.

This study aims to examine play as a phenomena from a phenomenological approach. This I do by discussing a dominant approach to play, an perspective which is reproduced in the context of pre-school and in where the play and learning is in single focus. Using alternative perspective on play, mainly by Gadamer and Bakthtins philosophical thoughts about the feast or the carnival, contents differ significantly from educational or developmental psychology perspectives. I open up for an understanding of what play as ontology can be understood as, and thereby enable second readings. I illustrate this thought by an empirical example from a pre-school context which where created alongside with the children in the study.

This thesis puts focus on Maria Aarts method "Marte meo" (on one's own strength). With the video camera as a principal tool, the purpose of the method is to be a practical working tool to support developmental processes on specific target groups, for example parents and their children. The aim of the thesis was to describe Swedish Marte meo Therapists and Marte meo Supervisors personal- and working experiences of the method, which was introduced in Sweden year 1991. Central questions were: How does Marte meo Therapists describe the essence of the method, it's establishment, development, and future in Swedish social services and psychotherapeutic treatment work? Which are Marte meo Therapists opinions of the methods relation to general problems and issues within social services and psychotherapeutic treatment work, such as the anchorage of theory and practice and the general claim for more research in social services interventions? In order to achieve the aim of the thesis a qualitative study was performed containing semi structured interviews with three Marte meo Therapists (two of them also titled Marte meo Supervisors).

Women?s strive to reach higher leading positions and build a career that's combinable with child birth and private life, is an on-going debate among academics in the fields of leadership, management and organization. This bachelor level thesis is written at the section of Management & Organization at School of Business, Economics and Law in Gothenburg, Sweden, spring semester 2015. In our research methodwe have used source triangulation with a qualitative approach to the subject of egg-freezing in favour forcareer with a focus on Swedish workplaces. The purpose has been to illuminate, map out and further problematize how the introduction of the employee benefit in November 2014 can be seen to relate to social sustainability.A lot of the management research that discusses social sustainability tends to focus on how women (and men!) try to balance family life and career and how to combine (or to not combine) them.

The aim of this study was to identify what kind of masculinity is shown in 54 articles of the Swedish lifestyle magazine Magazine Café of 1993 and 2008, and in which way this masculinity may be different from eachother.The study included four magazine issues of each year with analysis focus on main articles and abolishment of reviews and press items.  The method was semiotic analysis with focus on manly characteristics and stereotypes. The result showed that the normative man pictured in Magazine Café in 1993 was a man?s-man interested in manly characteristic business as sports, outdoor adventures and women. Fifteen years later not much has changed. The manly characteristics are the same but they have been complemented with a man-by-man accepted and homosexually inspired vain..

Swedish students' knowledge of mathematics has deteriorated in recent years. Teaching of mathematics is therefore starting point in an ongoing discussion among researchers, school leaders, politicians, teachers and others, who all thinks they know best about how teaching should be designed to the greatest extent possible to raise students' proficiency levels in the subject. Teachers' practices have long been the focus of discussions and views on these differ. The purpose of this paper is therefore to study students 'conceptions of mathematics and mathematics teaching, with teachers' methods and tools of focus, in relation to previous research on the subject. The method used was a survey of students in secondary school and a textual analysis of previous studies on the subject.As revealed by the survey was that the textbook has a big advantage in mathematics education in Sweden today.Many students are not accustomed to working in a different way and thereforedoes not know either what the alternative approach entails.

This exam is about student?s perception of food and dietary advice. I illustrate food and eating from the youth's own perspective. The aim is to investigate how students perceive as "good" diet. It also reveals that students at the surveyed schools have poor knowledge of what is plate model.
