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.

The aim of this study is to investigate how and in which form students come in contact with practical applications in the upper secondary school course Chemistry B. The study is based upon the assumption that all learning is situated in a social environment. The theoretical framework is the design theory perspective, which entails an assumption that the pedagogical tools affect the knowledge content.The empiric materials in the study are collected through three methods: textbook analysis, classroom observations and questionnaires. Two groups of students and their teachers were observed during a section of the relevant course. The textbook analysis focuses upon the same course section in the textbooks of the two groups and compares these books with the relevant section in a third textbook.

Background: A group severely affected by health issues, the experiences of homeless alcohol and drug abusers in the coverage of their medical care needs is not satisfactory. Aim: The aim of the study is to explore which factors experienced by homeless alcohol and drug abusers in Uppsala in regards to their living situation affected their health, their perception of access to healthcare, the character of treatment received and coping strategies used outside of the healthcare system. Method: Nine people who had experienced both homelessness and substance abuse problem were recruited for the study during their visit to Stadsmissionens facilities for the homeless. Data was collected through qualitative, semi-structured interviews including two women and seven men. Data was analyzed using qualitative content analysis according to Giorgi modified by Malterud.Results: Among homeless substance abusers interviewed experiences of unwelcoming and prejudiced healthcare were described.

The aim of this study was to understand how social workers perceive and understand violence and threats of violence from clients, and how it effect their working environment. It seems that the respondents understand the violence and threats of violence from clients as a result of the clients background problems, vulnerability, dependency and from ?the reason" that the client is currently in the contact with the organization. How respondents interpret the client´s behaviour based on the above-mentioned factors, seem to determine how the respondents perceive and define the violence and threats of violence by clients directed against them. Interestingly enough, although all respondents in the study experienced violence and threats of violence from clients, none of them perceived themselves as exposed at work. The answer to this is consensual.

?Life on a delicate thread?Baptism and godparenting in Bottnaryd and Ulricehamn 1781-1783The aim of this study is to discover if there were differences between the baptism traditions maintained in a typical rural parish and in an urban town parish in the period 1781-1783 and to suggest possible reasons for any differences found. Baptism records from rural Bottnaryd parish and the town of Ulricehamn were studied and compared. In both communities, parents were anxious to have their child christened on the day of birth or the day after. They did not want to wait until the following Sunday, as church law prescribed. Infant mortality was high and if the child died before it was christened, it would not go to heaven.

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

Background:The value a consumer connect with a certain brand and its design differ from person to person. This value ought to be investigated. Why does people buy expensive things when there are cheaper alternatives? Is it brand equity and/or the perception of a brand?s value that make a difference? People strive to show themselves and to perform through products, which makes it interesting to see to the perceived value of design.Tweens is a group of consumers that are easily influenced to consume products by their surrounding. To choose clothes, shoes and other products after what your surrounding?s demand, is a way of adapting yourself to society.

A more complex and turbulent world market puts pressure on flexibility and the ability to adjust its business to the market changes.

Handelsbanken is a company that uses the so called Beyond budgeting concept and the dissertation is about this company?s ability to solve the economic governance without the traditional budgeting process.

This study aims to increase the understanding of how some teachers and special education teachers work and relate to pupils with difficulties, and in which way they use guiding documents in their daily work. Over the last four decades the curricula in Sweden have aimed at creating a school for everybody though, without any significant success. Today, many students leave the comprehensive school without grades in the subjects Swedish, Maths, and English. Since the obligatory school was introduced, pupils that have been considered un-normal have been sorted out to other groups and classes, where teachers with special competence have been working.The designation ?a school for everybody? is described in perspective from four different definitions.

We have chosen to write our essay in collaboration with Varbergs kommun, where our starting point is to improve energy efficiency by management control. Their occupation separates from a pure profit driven corporation and therefore the management controls have to be adapted accordingly.  The reason why we have chosen to write an essay about the management control opportunities to improve the energy efficiency depends on two different reasons. The first reason is that we find it very interesting, how with support from the management control it is possible to improve different parts of the operation. And the second reason is that Varbergs kommun expressed a wish that they wanted to improve their energy efficiency process.The purpose of the essay is to describe and analyze the opportunities with support from the management control to help improving the process of energy efficiency in a municipal operation.

This master thesis encompasses an inventory and risk classification of four disused landfills within the municipality of Uppsala, Sweden. The model of the classification; ?Method of Surveying Contaminated Sites? is developed by the Environmental Protection Agency and can be used as a framework to investigate and describe the environmental damage and the level of risk for each object. The risk classification model has a rating from 1 to 4, where 1 represents a very high risk while 4 is a small risk. Risk class depends largely on the type of land use that exists on the object, and hence, various benchmarks must be taken into account.

The Swedish legislation (Socialtjänstlagen, SoL 5 kap 1§ 6 st.) state that the social welfare committee is particularly responsible for those children whom are in need of support and help after an adoption or custody matter has been decided. "Adoption - but at what price?" SOU 2003:49 is a state report with the purpose to investigate different aspects around international adoptions, which brings up and discusses what supports there is for adoptive families in Sweden. With this background and a special attention towards adoptive children's health conditions when arriving to their new country we decided to study the subject adoption. By interviewing different professionals and volunteers that work with adoptive families in Sweden the aim with this study was to acknowledge how they look upon the support the Swedish community offers for adoptive parents and also how they consider the knowledge about adoption among those who in their line of work can meet adoptive children is.
