Introduktion: Dental erosion definieras som förlust av tandens hårdvävnad genom en kemisk process som inte involverar bakterier. Dagens förändrade livsstil och kosthållning medför att våra tänder oftare utsätts för kemisk påverkan som kan leda till erosion. Det är flera faktorer som samverkar och dental erosion har en multifaktoriell etiologi.Syfte: Syftet är att beskriva olika registreringsmetoder för dental erosion.Frågeställningar: Vilka metoder kan användas för registrering av initial erosion? Vilka metoder kan användas för registrering av avancerad erosionsskada? Vilka metoder är kliniskt beprövade på patient?Metod: LitteraturstudieResultat: Ett flertal registreringsmetoder fanns beskrivna i litteraturen, merparten var inte applicerbara kliniskt. Registeringsmetoderna som framgick i den beskrivande litteraturstudien var: 3D scanning microscope (IFM), Atomic absorption spectroscopy (AAS), Digital photography (DP), Focus-variation 3D microscopy (FVM), Longitudinal microradiography (LMR), Non-contact confocal laser scanning microscopy (CLSM), Optical assessment, Optical profilometry (OP), Quantitative light-induced fluorescence (QLF), Scanning electron microscopy (SEM), Stylus profilometry (SP), Ultrasound, White light interferometry (WLI) och X-ray diffraction (XRD).Konklusion: Vid registrering av initial erosion krävs analys av tandytans mineralinnehåll samt optiska analyser med hjälp av instrument.

Den här studien är gjord på initiativ från Bodens kommun som upplever att det inte finns någon generell standard för hur digital ekonomisk och finansiell information bäst kan bevaras långsiktigt. Med ett avstamp i vad jag ansåg vara relevant teori, genomfördes studien med hjälp av semistrukturerade intervjuer med personal från ekonomiavdelningen och analyser av dessa..

The aim of this Masters thesis is to review Swedens unique law against TV-commercials intended for children under twelve years old. The law has to be abided by TV 4, but not by Kanal 5, so the aim is also to compare TV 4 and Kanal 5 and to see in what different ways commercials are shaped in the two channels. The cultural policy analysis is based on our aim and problem. We have also had the terms semiotic and intermediality in mind together with a model made by the researcher in semiotics Roman Jakobson. The model consists of six different communicative functions.

DARC är ett sätt att sända digital information via FM-rundradionätet. Moduleringsmetoden för DARC är GMSK. Målsättningen var att jämföra kostnad/komplexitet och strömförbrukning för olika sätt att demodulera GMSK. Tre icke-koherenta demodulatorer och en koherent demodulator har jämförts. Man vill veta hur stor resursanvändningen var för olika FPGAer.

This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.

The aim of this thesis has been to analyze and interpret several different discourses in Japan and from the findings see how the Ainu people and their existence in Japan have been defined in today's Japan and in who's interest it is to keep it this way. My findings was that the Japanese nation in all channels of society are reinforcing and perpetuating the belief that it constitutes an ethnically homogenous nation and that there exists no ethnic problems in the country. I found that schoolbooks don?t give adequate information about the Ainu people and its history, and the Japanese press is reinforcing the status quo by their selective silence and limited coverage on issues concerning the Ainu. The government has defined and legitimized the problem of Ainu within the framework of culture and tradition.

 The purpose of this study is to examine how individuals' social capital can affect the opportunities for finding a job. That is, what benefits social contacts can provide in the hunt for a new job. The main questions that will be answered throughout this study are:- Of what importance are social contacts when looking for a job?- What are the advantages and disadvantages that the respondents present with recruitment thru informal channels/social contacts?-What are the advantages and disadvantages that social contacts can provide in terms of personal recommendations when looking for a job according to the recruiters?The study is based on five qualitative interviews with mainly recruiters from various parts of the labor market. The collected empirical data that the study has yielded indicate that individuals' social capital of the highest degree is crucial for the opportunities they have to find a job.

In organizations today Corporate Social Responsibility (CSR) is becoming a common means to try to gain legitimacy and credibility for their business. A successful CSR strategy has the potential to generate positive outcomes for a company and reaching out to stakeholders about the corporation?s contribution in the field is an important part of the work. In this study I examine how the employees at Max Hamburgare receive the corporation?s efforts within sustainability, how it is perceived and what this means to the employees.

Abstract CORDIC (Coordinate Rotation Digital Computer) is an iterative algorithm for the calculation of a two-dimensional vector in circular, linear or hyperbolic coordinate systems. This paper presents a survey of known CORDIC algorithms and architectures for the rotation and vectoring mode in the circular cordinate system. In addition an implementation of the differential CORDIC algorithm in VHDL has been done. The implementation is designed to keep the fast timing and throughput characteristic known for on-line redundant arithmetic..
