Målet med detta examensarbete, utfört på uppdrag av Vectura Consulting AB, har varit att undersöka möjligheten att ansluta en vindkraftpark till järnvägens kontaktledningsnät. Möjligheten att koppla om vindkraftparken till järnvägens hjälpkraftnät, som bland annat förser växelvärmare och signalsystem med effekt, har också undersökts. Eftersom kontaktledningsnätet och hjälpkraftnätet arbetar med olika frekvenser och spänningar, 16? Hz och 15 kV respektive 50 Hz och 22 kV, måste därför en komplett krets för frekvensomvandling, spänningsomvandling och omkoppling tas fram. Projektet har begränsats till en del av Botniabanan, sträckan Örnsköldsvik-Nordmaling.I denna rapport har trafikfrekvensen på den valda sträckan på Botniabanan undersökts för att bestämma en genererad effekt till inkopplingspunkten, samt för att undersöka när det kan vara lämpligt att koppla om till hjälpkraftnätet.

Syftet med studien var att undersöka vid vilken situation som simmare använder visualisering mest och varför samt simmarnas visualiseringsförmåga. I studien deltog 278 simmare (15-30 år) i den kvantitativa delen och 3 simmare (17-23 år) i den kvalitativa delen av studien. De instrument som tillämpades till den kvantitativa delen var en konstruktion av SIAM och IPIES som tillsammans mäter idrottares visualiseringsförmåga och användning. Till den kvalitativa delen användes en semikonstruerad intervjumall. Resultaten från studien visade att det fanns några statistisk signifikant skillnad mellan högpresterade och lågpresterande simmare i visualiseringsförmåga.

The aim of this study was to examine young people?s experiences of participation within the intervention Contact Person. Three questions were asked concerning young people?s experience of participation, aspects that promoted/limited the young people?s experience and the significance they attached to the intervention. The findings in this study are based on phenomenological interviews with five teenagers within the intervention Contact Person.

The purpose of this Master's thesis is to investigate the role of the public library when the local government in the municipality arranges distance education at university level. The thesis has two main areas of questioning and these are goals and resources. In the study it is examined if the local goals have changed during the period 2000 until 2005, due to the development of distance education. It is investigated if change actually has occurred and if it has, in what way the goals have changed. It is also examined if and how the goals correspond with the work that is being performed in the public library.

The following essay aims at the interplay between regional och municipal growth work, and theway cultural heritage is used in growth work strategies. The main issue has been whether theregional strategies are followed up in the municipal strategies, which has been investigated bymeans of question which impact the region?s strategies has at the local level.The essay draws upon an instrumental perspective on cultural heritage and cultural environment,here defined as instruments in the national development and growth efforts. Three publicationsthat highlights potential roles of cultural heritage and cultural environment to act as instrumentsin the regional and municipal development and growth efforts has thereby been selected astheoretical models. These roles has further been summarized in a tabular form as a schematicdivision of main themes with sub-categories, used as a framework for deciphering the regionaland municipal strategies.A content analysis of available strategies at both regional and local levels have been used as amethod for investigating the issue, where the role of cultural heritage and cultural environment(as defined in the schematic table) has guided the reading.

This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

The relational database model was defined in the 1970?s and is the dominating database type today.  The main difference between data from a relational database and a hierarchical data structure is that the relational database stores records in tables. The records have no particular order, but can include links in terms of relationships with other records. A hierarchical structure organizes data in the form of a tree structure  and  can for an example be found in organizational structures in which different levels involves different responsibilities. If the data stored in a relational database is to be presented in a hierarchically, a conversion of the data structure is required. The intention of this paper is to describe how such a conversion can be performed.  To investigate the conversion methods, case studies has been conducted on the basis of a specific organization?s hierarchical structure.

The amount of various phosphorus (P) fractions in the sediment and the relationship between the amount of P and sediment particle size were investigated in a constructed wetland southwest of Linköping. Furthermore, the possible correlation between clay content in the sediment and distance from the inlet was investigated. Sediment samples were collected along three transects from the inlet to the outlet, with six samples in each transect. In order to measure the soluble P, an NH4Cl extraction was done. This was also analysed for total soluble P after oxidation with peroxodisulphate.

This report is the outcome of an exam work made in interaction design, bachelor degree, at the School of Arts and Communication, Malmö University. Working in collaboration with the childhood obesity unit, Region Skåne, our aim was to fulfill their request of a web based application preparing the children for treatment at their facility. Furthermore the application intends to give the children knowledge concerning obesity as well as teaching them how to obtain a healthier lifestyle in terms of provision and activities. The application concerns children in different ages and therefore different stages of their learning abilities. Our conclusions are that they need to be challenged and obtain feedback in different ways to get motivated.

The aim with this master thesis is to study which ambitions and strategic aims Gothenburg?s district libraries have regarding their music sections. I have utilized my theory from Sanna Talja, a Finnish researcher in Library and Information Science. She identifies three perspectives in maintaining a music library. She calls them, general education, alternative and demand.

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

The purpose of this study is to illustrate teacher humor by critically examining it from an interpersonal- and humor communicative-perspective; and to discuss teacher interpersonal humor communication-skills in relation to the Swedish high school curriculum, collegial relationships and pedagogical aspects. The study?s empiric material consists of semi-structured interviews with six high school-teachers currently working at the same school, but of different age and gender. The interviews indicate that the informants all have developed humor competence, an interpersonal communicative-skill that allows them to use humor efficiently. Moreover, the result demonstrates that the teachers have various humor approaches but that they all use humor in the classroom for much of the same reasons.

Researchers claim that stress has become a word of fashion and is now frequently used. They also state that there is no accepted definition that can easily describe the concept. In this essay, I have examined children and stress. The aim of the diploma work is to illustrate stress more closely the stress concept, the underlying reasons that can influence children and how teachers and school staff support children in their stress handling. My three issues are: What is stress? What stressors put children, at home and at school, in a stress situation? How can teachers help children to manage their stress? The diploma work is based on a literature study in order to find out what has been written on the subject in earlier research.

The question how teaching should be organized in order to give the students the help and support they need to reach their goals is always of vital interest. All students are unique individuals with different prerequisities, possibilities and needs. Streaming in mathematics could be one solution.The first week at upper secondary school a diagnostic test is carried through. Thereafter, the result is used as a basis for dividing the classes into different teaching groups. Thus, the groups working with mathematics become more homogeneous and the students? previous knowledge is approximately at the same level.
