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.

The way we design our cities today will affect the living conditions for future generations. Planning as a discipline can become crucial to attain a sustainable urban development with an increased quality of life among the urban population and an improved environment. Urban Agriculture in the Sustainable City -a case study in Managua is a Diploma Work that deal with poverty issues, aspects of sustainability and development work. We have had a theoretical starting-point, but our focus has been on the case study i.e. the practical part, that we carried out in Managua, the capital of Nicaragua. Today about half of the worlds 6,3 billion people live in cities. The demographic growth of the countryside has declined, while the population in the cities is considerably increasing.

It has now passed two years since the new site- and construction law, PBL, went into force. It replaced the previous PBL applicable since 1987, and it involves relatively large changes in many different areas of the construction sector. The ambitions of the new law are for instance to simplify and clarify the legal text, increase efficiency in the permitting processes and improve the quality of construction. To achieve this, a variety of changes was made. Some of the most important are: inserted deadline in the processing of building applications, extended assessment of building applications, revised rules about controlplan and quality manager, a certificate is required to start and end the project, an additional meeting is inserted and the construction management of the municipalities will have to do a mandatory visit at the work scene.

The present study is embedded in the research field of Personal Information Management (PIM) and its goal is to contribute to this research area by showing information management aspects in untraditional contexts, as in the social networking site Twitter. The aim and purpose of this two year's master thesis was to investigate the beha-viour of librarians within the context of Twitter. The objectives of this thesis focus on the query of the informa-tion management aspect of Twitter, and on the investigation into whether Twitter offers the possibility to reach a state of flow while using it, as well as inquiring into the relationship between Mihaly Csikszentmihalyis flow theory and PIM. The theoretical framework of this thesis is centred upon the flow theory and the conditions that are necessary to reach a state of flow. To fulfill the purpose of this thesis a directed content analysis is applied as an investigative method, where its in-depth research aspects will be applied upon the empirical material, which contains 429 tweets.

This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.

The pupose of this study is to qualitatively study how teachers at a high school work with the schools demokratic mission under the management by objectives and what the policy document says and how the students can partcipate in different issues. My question fomulations are: What does it say in the governing documents about schools democratic mission and student influence? How do teachers concretely work to implement the values of democracy and student influence? How can the class councils used as part of the school's democratic mission? The theoretical frame of the study is about the school democracy mission and the possibilities and limits.  Futhermore a brief review of the fundamental values of the school are presented, followed by how the democratic process works.I used the qualitative analysis in order to find a lot of information about a small amount. Its strength is to convey a lot of information about a small number of observations and if the material is small in size.

This essay deals with the industrial past, present and future and begins with the impact and importance the industrial revolution has had on us humans, socially, economically and structurally. Today's society has developed from industrial production of goods to the production of services but the industrial sites remains. The essay examines issues concerning the protection of the industrial environment, their status as a cultural heritage, what is done with our industrial heritage and the opportunities it has for the future. Malmö has a great industrial history and now one of the cities oldest industrial sites, the north of Sorgenfri, will be transformed. The essay compares the plan with guidelines for future development from the Town Building Office with an antiquarian investigation for the same area.

English title: Part-time work among women in Sweden ? what influences choice of working hours? In the 1960s and 70s a large growth in part-time work amongst women in the Swedish labour market took place. A net inflow of workers into the labour market has been suggested as the main source. However, part-time work is still a common phenomenon among Swedish women; in 2004 almost 40% of all women worked part-time, and women are clearly dominating the part-time sector. A gradual changeover from house work to market work is hardly a valid explanation anymore.

In recent years, the right-wing extremist site Avpixlat (?Unveiled?) and the anti-racist blog Inte rasist, men... (?Not a racist, but??, IRM) have established themselves as political actors and platforms for political discussion in Sweden. However, we know very little about them and their impact on democracy.

Although Dan Andersson (1888-1920) is considered perhaps the most important of the early Swedish workingclassauthors, there has not been much research on his work. Through a perspective based on critical whitenessstudies, intersectionality and existential phenomenology, this thesis performs a close reading of Andersson?sKolarhistorier (1914) and Chi-mo-ka-ma (1920) in order to map the discursive formations of whiteness andblackness in the texts, as well as to expose how these formations interrelate with that of humanhood.Since an underprivileged situation of oppression and poverty is the point from which the fictional worldunfolds in both Kolarhistorier and Chi-mo-ka-ma, whiteness is not an existential style within close reach for thecharacters. In Kolarhistorier the charcoal-burners claim themselves as ?weary of whiteness? and accordingly thetext establishes what the thesis reads as a realm of blackness where the black, male body becomes a locus ofpleasure instead of despair.

Newspapers have undergone big changes with the progress of Internet and the newspapers establishment on the Internet. This adjustment to the Internet has resulted in differences between the content in newspapers and Web news sites. A quantitative content analysis and questions to Web authorities have been used in this study to describe what these differences are. During three days, three different newspapers were analysed and the conclusion was that many of the articles that were published in the newspapers also could be found in the newspapers Web versions. At the same time a lot of the articles on the Web news sites were not published in the newspapers.

The inequality and separation of sexes seen in organizations may lead to inefficient use of human resources. Therefor, a more equal organization could lead to higher productivity and efficiency. Inequality within organizations is a problem also for the society as a whole since who is chosen for a position is not depended upon merits, leading to inefficiency. To not reflect upon traditional division of labor and decision-making could also lead to an undemocratic and unjust society. The aim of this thesis is to explore women and men?s engagement a family business in an agricultural setting. Gender theorists argue that gender arises from the social situation in society.

As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.
