This report examines the prerequisites for LEDs to replace other technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a test-construction built to examine what practical arrangementscan be built with modern light emitting diodes, in order to showsome of the possibilities. The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

The swedish national board of housing, Building and Planning,recommends that all stakeholders in the construction industryperform a moisture control design to make sure that the buildingachieves good moisture resistance. Since June 1, 2006 there are nospecific requirements or quantitative values for air leakage.Although the swedish national board of housing does presentrequirement that the building envelope must be sealed so that theclient?s requirements for specific energy consumption and installedelectric power for heating purposes are met. Despite this, studiesfrom SP shows that few buildings meet the client?s requirements inspecific energy, which increases the risk of occurrence ofcondensation-related moisture damage.This study aims to evaluate curtain walls connections from airsecurity and moisture safety.

Aim: To examine how midwives describe good and safe postpartum care of mothers with infants in neonatal care, and which prerequisites and obstacles they see to giving good and safe care while minimizing time of separation. Method: Semi structured qualitative interviews with ten midwives at two maternity wards in Uppsala. The interviews were recorded, transcribed verbatim and processed by manifest analysis. Results: Three categories were identified, Good and safe care, Organization as an obstacle and The midwife role. Good and safe postpartum care of mothers with infants in neonatal care required knowledge, appropriate equipment, good guidelines, possibility to see the mother, contact between mother and infant and good collaboration between the maternity and neonatal wards.

The aim of this study is to describe how pupils in fourth grade talk about their attitude of reading fictional narratives in school and on their spare time, their motives to read and how the school promotes fictional experiences. The study is based on interviews with 18 pupils from the same class, divided in four groups. The interviews were analyzed from a literature reception theory. The result shows that some pupils are very engaged in reading fictional narratives, while others more or less, are forced in to reading, because their teacher wants them to. All the interviewed pupils would like to read exciting, interesting books, but they feel that they don?t get the right support neither from their teacher, parents nor their friends. They describes that they don?t discuss the meaning of reading or things that the reader can read between the lines.

The purpose of my study is to contribute with knowledge about three teachers? view on the possibilities and difficulties to support students with intellectual disabilities insocial interaction.to get answers to my research questions in the analysis I have in my qualitative study used the theory of Fleck's model about thinking styles rooted in a socio-cultural perspective. In the study, I have used semi-structured interviews. My study shows that teacher?s way of thinking affect students' opportunities to practice social interaction. An important finding in the study was that the school management?s attitude, is of great importance for educator?s opportunities to support the students with intellectual disability in social interactions.

The purpose of this study is to investigate how children search for and choose picture books while visiting the library together in a preschool group. How do children interact with each other and their teacher while searching for picture books? Which aspects of children's everyday lives are apparent in their choice of picture books? The theoretical frame of reference consists of Brenda Dervin's sense-making approach to information seeking and William Corsaro's sociological approach to studying children's routine activities within a peer culture. To capture children's interaction, we have observed a preschool group consisting of six 3- to 5-year olds and their teacher in a library setting during three visits. Our study shows that children's search for picture books is a social activity that involves various verbal and nonverbal strategies in order to include and exclude each other when they find a picture book that interests them.

Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.

The aim of this essay is to create an understanding, of how teachers comprehend knowledge, grades and tests in a school context. It is important to get a grip of the different parts of the teacher?s reality. The test, the grades and knowledge are deeply connected as a part of a whole. The teachers view on knowledge can not be understood without asking about the practical parts of their work and understand how the different parts are dependent on each other.The main material consists of interviews with four teachers that work in a public mandatory school in the south suburbs of Stockholm.

This thesis has been carried out onbehalf of Lindborg & Sons in Örsundsbroand is a concluding part of the Bachelorof Science program in ConstructionEngineering at Uppsala University. Theaim of the project is to make a plea fora database of good examples of themachine room types using Revit drawingprogram, and work out a correspondingworksheet .At the start of the process it becameapparent that there were somedifficulties in using Revit to creatingmachine room types of the variety whichthe company builds. For modelling ofoblique, curved and irregular lines, Ihad to use my AutoCAD Architecture andthen import them into Revit.The creation of calculus in Excel wastime consuming. On the other hand, it isa one-time work to create the template.The advantage of Excel is that there isno need for a re-calculation at the costof various types of machine hall. Allthat is needed is to replace the variousparameters.

The Swedish curriculum points out mathematical communication as one of the importantabilities that students need to develop. Previous studies show that students have not been given the right conditions to develop this ability sufficiently. The purpose of this study is to investigate how some Swedish teachers interpret mathematical communication and how the work with this takes place in their classrooms.The investigation consists of qualitative interviews with six teachers in the grades of Fk-3. The interviews have been focused around the teacher's interpretation regarding mathematical communication, how this is reflected in their work in the classroom and also if they see any advantages or difficulties in working with mathematical communication with their pupils.The result of the study shows that the teachers are well aware of the importance of communication and they have a will and an intention to let the pupils communicate mathematically. Mathematical communication is emphasized mainly as important for the pupil's learning and understanding.

Utifrån tidigare forskning om och utvärderingar av musikämnets ställning i lärarutbildningen är syftet med förestående uppsats att ytterligare belysa musikämnets situation i den svenska lärarutbildningen såsom den manifesterar sig i kursplanerna på högskolor och universitet. Föremål för analys är samtliga lärarutbildningars kursplaner i det allmänna utbildningsområdet (AUO), som tillsammans med den nationella kursplanen i musik (Kp2000) utgör underlag för besvarandet av forskningsfrågan ?På vilket sätt förbereds lärarstudenter för musikundervisning enligt Kp2000??. Ur ett hermeneutiskt perspektiv genomförs analysen baserad på fyra sökord; ?Musik?, ?Estetik?, ?Musisk? samt ?Konstnärlig?, ord hämtade ur den presenterade kontexten kring analysobjekten.

The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.

The aim of this study is to examine marriage as something both desirable and normal in three popular novels from the 1860s about marriage: Rosa Carlén?s Agnes Tell: en äktenskapshistoria (1860), Marie Sophie Schwartz?s Alma eller De moderna äktenskapen (1860) and Sara Pfeiffer?s Aurora Trampe (1867). Using a theoretical perspective from Michel Foucault and Judith Butler, I have analysed the novels as being producers of, and resistance against, norms.The good marriage is partly depicted as a utopian vision in the novels, which therefore functions as fantasies for the readers. But it is also depicted as a realistic possibility. Though difficult to achieve, the main characters reach the goal through individual improvement towards correct behaviour.The question for the main characters is not whether they are going to marry or not, but how to make their marriages good ones.

Construction of Identity and Charismatic Leaders deals with fundamentalism and Islamism within the United States, emphasising on similarities between fundamentalists and Islamists. The term "fundamentalist" is here referring to Christian extremists, while "Islamist" refers to the Muslim counterpart. The purpose of the essay is to make North American fundamentalism and Islamism comprehendible on a larger scale.In order to show similarities between these groups when it comes to values, structure and commitment to their tasks, it is important to understand the nature of the religious devotion.Analyzing the similarities of the two groups enables construction of general criteria for how anthropology of religious extremists can be outlined..

The use of out-door pedagogy in the school has been frequently high-lighted during recent years. To which extent out-door education was practised in the school depends on the opinions among the active teachers. The aim of this study was to examine the opinions on out-door pedagogy among teachers in classes 4-6 of the elementary school and to find out to which extent the teacher used out-door teaching. The study was based on qualitatively structured interviews with 4 teachers having different lenght of teaching experience. The results of the interviews showed that the teachers had different opinions on the definition of out-door pedagogy.
