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.

Kärnkraftverk är högteknologiska system med hög komplexitet och utan att hantera den här komplexiteten kan små olyckor få katastrofala följder. Närvaron av komplexitet försämrar förmågan att förstå situationer, minskar kontroll samt ökar risken för incidenter. Stabsarbete inom kärnkraftsdomänen kräver ett agilt beteende för att hantera den höga närvaron av komplexitet. Agilitet är förmågan hos en enhet att framgångsrikt genomföra, hantera och/eller utnyttja förändrade omständigheter. Syftet med arbetet är att utveckla ett mätverktyg för att identifiera indikatorer på agilt beteende i stabsverksamhet inom kärnkraftsdomänen.

This paper is a qualitative analytic study of the views regarding masculinity of six male university students. The author means to view the gender issue from a male point of view and analyze the empiric result using well known theory on the subject. The main questions of the essay are: What, according to my respondents, is masculine and non masculine? Does the university influence this view, and if so how? How is it to be a man in the society of today? The paper is based around interviews of the six subjects, recorded and transcribed and analyzed in a systematic outline. From this outline relevant themes has been constructed and compared with the theory.

The aim of the study is to examine how the executive leadership and the decision-making process are shaped by the leadership environment in a transition democracy as Venezuela. The questions I intend to answer are: What kind of leadership environment surrounds the leadership and what kind of consequences does it have on the leadership and the decision-making process in Venezuela? To answer my questions I will use the literature: Political Leadership in Liberal Democracies (Elgie, Robert 1995, London: Macmillian), together with the method ?The cultural determinist school of history? by Tomas Spencer, later reproduced by Kellerman. The leadership environment provides unique opportunities for a leader to gain control over the decision-making process. Institutional structures and the needs of the society are major parts in determining how the political leadership is exercised.

In this two years master's thesis a regional project, Futurum.kom, is studied through the experiences of eight librarians from two of the participating libraries. The interviewees have all attended local and regional seminars where questions about core values, target groups and the role of the public library were discussed, among others. The seminars resulted in a number of core values and target groups. During the project, a number of advertising campaigns are to be conducted. The first one of these had recently been implemented at the time of the present study. The aim of the thesis is to investigate the interviewees organizational self-perception in relation to the project.

In this study we try to focus on the costs for wear parts on different type of soil tillage machines and at Väderstad Rapid drilling machine. We have studied some of the leading types of cultivators and disk harrows. Among the cultivators we have investigated Väderstad Cultus, Dalbo Dinkomax, Horsch Tiger and Terrano. At disk harrow we have looked at Amazone Catros and Väderstad Carrier. We have made more detailed study on costs for wear parts, working depth, driving speed and diesel consumption.

Bakgrund: Gingivit kännetecknas av svullet/lättblödande och ibland ömt tandkött. Gingivit är en inflammatoriskt orsakad reaktion som uppkommer i samband med närvaro av bakterier. För att motverka utvecklingen av gingivit rekommenderas munhygienvård regelbundet. Gingivit kan utvecklas till parodontit med skador på upphängningsapparaten och benstödet, orsaken till detta är idag dock ej helt klarlagd. Kliniska variabler (blödning vid sondering) är vedertagna diagnostiska metoderna för diagnostisk av gingivit idag.

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.

The purpose of this thesis is to investigate if there exists a superiority between developed and developing countries, which then in turn effects the negative consequences, for the local inhabitants of Thailand, that follow from mass tourism.To be able to answer the questions that we have selected for this thesis, we chose to perform open interviews with six respondents which were all involved in the tourism industry in Thailand. Four of the interviews were carried out on location in Thailand. In order to deepen our understanding of the selected questions even further literary studies have been made as well. The theories we have chosen concern the topics of imperialism and figurations.Our empirical material gave significant results. It showed that there is indeed an imbalance of power between the western world and Thailand.
