Molar Incisor Hypomineralization definieras som ett specifikt tillstånd orsakat av störningar i den tidiga fasen av emaljbildning av en eller flera permanenta första molarer med eller utan involvering av permanenta incisiver. Tidigare studier har visat att standardiserad intraoral fotograferingsteknik kan vara användbar för epidemiologiska studier av emaljdefekter. Denna studies syfte var att utveckla och utvärdera en fotografisk klassificering av allvarlighetsgraden av Molar Incisor Hypomineralization genom att studera metodens validitet och reliabilitet. 164, 10-12 åriga svenska barn granskades fotografiskt avseende prevalensen av Molar Incisor Hypomineralization. Först granskades endast första molarens ocklusalyta, därefter ocklusal- och buckalyta.

The present study discusses the political integration of immigrants in local government in the muncipality of Växjö from 1971 to 1991 in the form of representation. The main data source consists of lists of people holding local commissions of trust in the various boards and committés appointed by the municipality council, as well as in the council itself. These data are then compared to population statistics from Statistics Sweden. Main findings of the study are that immigrants are insufficiently represented in relation to their proportion of the population. It is suggested that this is a result of structural discrimination and possibly insufficient socialisation..

Lerbodaälven is a river in the municipality of Kil which, due to high phosphorus content is not meeting the requirements for good ecological status according to the Water Framework Directive. The purpose of this report is to investigate the causes for the high content of phosphorus that has been measured in Lerbodaälven between 1995-2010. Four questions will be answered in this report. 1. Does the sewage treatment work affect the phosphorus level in Lerbodaälven? The result from the time series analysis shows that the sewage treatment works have a small impact on the phosphorus level in Lerbodaälven.

The author is active as a musician in the field of historically informed performance practice (HIP) which emanated from the 20th century early music movement. Studying of historical sources has a central role, but the problem of how interpretation and selection of source material is affected by art and music ideals of our time, is commonly acknowledged. Georg Joseph Vogler shows in a series of articles in "Betrachtungen der Mannheimer Tonschule" (1778-1781) how Stabat Mater by Pergolesi could, and in his opininon, should be improved. The purpose of this thesis is to investigate how this source can be used from the standpoint of a performing musician: How can I use Vogler?s methods in my playing?The introduction problematizes Vogler?s action in relation to his time, and to ours.

The purpose of this thesis is to explore whether male kindergarten teachers perceive additional expectations from their surroundings (such as co-workers and parents). Furthermore, we aim to understand and explain how these expectations are related to gender norms and hierarchies in society, that is social constructions concerning what men and women should do and be like. In addition, the thesis aspire to understand and explain how these constructions relate to more specific social constructions about sexual molestations in kindergarten contexts and explore how these discourses influence male kindergarten teachers in their work including which strategies they use in order to cope with them.How do male kindergarten teachers perceive additional expectations from their surroundings?How do male kindergarten teachers perceive the effects and consequences of the social constructions about sexual molestations in kindergarten contexts? Do they use coping strategies in order to attend to the expectations projected on them, and if so, what kind of strategies? The thesis is based on a phenomenological approach and conducted through interviews with six male kindergarten teachers. The interviews were directed with an interview guide in hand while allowing for spontaneous input from the interviewee.

The aim of the work was to investigate the possibility to combine information from PPG and bio-acoustic technology to extract information that is related to the blood pressure. The measurements have been carried out with several different configurations. First the relation between arterial sounds and the PPG-signal was studied. After those measurements with both PPG and the bio- acoustic technique was concluded on people in different positions and after riding a bike. The goal was to vary the blood pressure.

Requirements engineering is a widespread topic in the research field of informatics. However, there is little research regarding lack of requirements documentation and how it is perceived. The same applies for how requirements engineering in retrospect can be implemented. This is a debated issue on blogs and forums but it has not been reflected in the research area.Therefore, this study concerns research questions regarding how the developers, testers and requirements analyst experience the lack of requirements documentation and how requirements engineering in retrospect can be implemented.To answer these questions, data collection has been conducted through qualitative interviews with individuals affected by this problem in their everyday work.This study has provided an explanation of how the problem is perceived and what the consequences are, both direct and indirect. The impacts are divided into three categories and are presented as, emotional consequences, system implications and consequences regarding re source consumption.

This final year project is made for Peab Jönköping and its target group is the construction industry. The main focus is the use of unutilized building material in the most economical and environmental-friendly way. Unutilized building material is here defined as material purchased for a construction project that for different reasons not has been used. The most important thing to find out was how much building material considered as being waste is actually useable material, and how much less it costs to use that building material instead of throwing it away.When this information was gathered a proposal on how to efficiently use the unutilized building material instead of wasting it was designed. Costs and incomes were investigated and the proposal suggested a storage area where Peab can store their unused building material.

This essay is about the history of the hearing aid in Sweden, from 1930s until today. The hearing aid as an apparatus is described, and views by the users are presented. Articles and interviews have been used as source material to answer the main questions. In the essay, people who have written the articles, and the ten users being interviewed, describe how hearing aids are used in everyday life, and how users interact with people in general and how the hearing care system treats users. Another question regards how users perceive their own hearing aids from an aesthetic perspective.

The jetengines of today are growing in complexity. Reliability for aircraft engines are of extreme importance, mainly due to safety reasons but also economical ones. This master thesis deals with faultdiagnosis in the turbine section of RM12, the engine used in Saab/BAe's Gripen. Three different faults which can occur in the turbine section was studied. These faults are: clogged fuel nozzle, hole in outlet guide vane and sensor fault.

The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.

Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.

This essay serves to illustrate the main practical differences between the popular medium-level programming language C++ (C Plus Plus), and the newer high-level language C# (C Sharp). It will focus on the aspects that are readily apparent to the application programmer, such as differing syntax, constraints and capabilities.It will also feature a similar comparison between the open source OpenGL graphics library, and the proprietary Direct3D graphics library owned by Microsoft Corporation.It will not go into the differences in ?under the hood? mechanics that the application programmer seldom have to consider after having chosen his programming language or graphics API, such as C# being compiled into an intermediate language and is run on a virtual machine where C++ is compiled directly to machine code, or the differing principles of rendering in OpenGL and Direct3D.This is by no means comprehensive, many things have been left out or overlooked..

The aim of this study is to study how sustainability policies are implemented and perceived in the operations of a Swedish fashion company. The fashion industry is affected by strict controls when it comes to transparency and reporting of sustainability efforts. This contributes to a strong focus on sustainability. The theoretical framework revolved around institutional theory where the phenomenas of decoupling and recoupling were central. A qualitative case study was conducted where interviews were the primary source of data.
