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.

Issues related to knowledge assessment and its consequences for both the individual and the entire school system are topical in today's school debate. The mere fact that didactic issues that focus on assessment are discussed actively not only in scholastic environments but even in media and other communities is further proof that knowledge assessment is an important and complex phenomenon in our lives.The subject that I have chosen to look into is about how the work with assessment issues is handled in Swedish as well as Russian elementary school's early years. The goal with this study is to see how my studies have been conducted with a qualitative approach by which I collected qualitative information in the form of documents, papers and interviews. To make the approach even more appropriate for my area of research, I have chosen to merge two qualitative research methods. The first is a qualitative content analysis which analyses the governing documents.

The aim of this study is to investigate how mathematics teachers use formative assessment to make the course objectives clear to the student. This is part of a wider aim in Sweden to find ways for improving mathematics teaching. Qualitative semi-structrured interviews and observations were used for collecting data. Different approaches to integrate formative assessment in their classrooms is discussed: questioning, discussions in whole-class, group work and assessment and feedback. The analysis of the results indicated that the teachers thought differently about how to integrate the course objectives in their planning.

In the current situation there is not much written about assessment of laboratory work, and the majority of the working physics teachers are retiring and there are only a few newly qualified physics teachers. The purpose of this thesis is to examine how physics teachers assess laboratory work within upper secondary schools, with Gy2011 in mind. The new grade system, Gy2011, has a larger focus on the laboratory work then the earlier system Lpf 94. Skolverket has in their man-ual with examples of assessment two different sorts of laboratory experiments. The first assess-ment is regarding the planning of a laboratory work and the other about how able the pupil exe-cutes laboratory work.

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.

Background: Patients postoperative pain is often underestimated. Untreated or undertreated pain decreases the chance of optimal recovery after surgery. Pain assessment is an important factor of efficient pain relief. Aim: The aim of the literature study was to describe factors of importance for nurses´ assessment of postoperative pain in patients. Method: A literature study was done where qualitative and one quantitative article was reviewed.

This study examines the effects of credit risk and information disclosure in the new bank regulating system Basel II on bank and bank customer. The effects are then discussed in a perspective of the economic man and information asymmetric theories. Furthermore is the Basel II effects on the capital adequacy of Andelsbanken för Åland examined.The approach of the study is qualitative and several interviews with individuals on different levels of the examined bank, Andelsbanken för Åland, have been carried out during the collecting of empirical facts about the effects of the regulating change from the Basel I system to Basel II.The research findings are as follows:Andelsbanken för Åland have increased its capital adequacy ratio from 12,7 percent to 14,4 percent, mostly due to lower risk weights on housing mortgages compared to Basel I. Andelsbanken för Åland have started to use a completely new credit risk and customer assessment system which classifies every customer and gives them a credit rating. The system cause a much heavier information gathering of the customers profile as well as a much better assessment of risk than the previous system, which the bank finds positive.

The thesis had its starting point in the first paragraph of the eleventh chapter in the Swedish social services act, which discusses the immediate risk assessments that has to be made when the social services receive a report about a child. The thesis highlights an area that has received a lot of attention in media since the spring of 2014, when an eight year old girl was fatally abused by her legal guardians. The social services had at the time received a report about the girl but it was left unread. This tragic case has brought attention to the routines used by the social services for dealing with reports and risk assessments. This thesis was conducted through individual interviews with social workers working with children and families in the social services, with the aim to acquire an enhanced understanding of how social workers perform immediate risk assessments and what these assessments are based on.

För att undersöka interbedömarreliabiliteten i Emotional Interaction Style ? assessment (EIS ? assessment), vid bedömningar av Marschak Interaction Method (MIM), har tre inspelade MIM filmer skattats av sju bedömare. Reliabiliteten beräknades med intraklasskorrelationskoefficient (ICC). I bakgrunden har en teoretisk genomgång gjorts av aktuell forskning gällande barns utveckling och samspel mellan barn och föräldrar. Vidare har bakgrunden till MIM och EIS-assessment redovisats.

This Masters thesis deals with query expansion in an online library catalogue. The aim of the study was to compare the retrieval effectiveness of four different query types when applied to the online library catalogue of the University College of Borås. The query types were: an initial query, the initial query with right hand truncation, the initial query expanded with synonyms and finally the initial query expanded with synonyms and right hand truncation. 24 topics were formulated, and four queries for each topic were constructed. The records retrieved by the searches were judged with regard to topicality, and were judged to be non-relevant, partially relevant or relevant.

This essay deals with risk management and social risks, which have received increased attentionin recent years. Methods for dealing with social risks, for example within local Risk andvulnerability assessment (RSA), are currently under development. The purpose of this paper is toexamine if and how social risk can be quantitatively assessed and mapped using GeographicInformation Systems (GIS). The definition of social risk that the essay is based on states: "Theprobability of unwanted events, behaviors or conditions originating in the social conditions thathave a negative impact on the objects that are worth to preserve.? A number of social riskindicators that can be used for a spatial analysis have been operationalized based on thisdefinition.

The market risk premium is one of the most important parameters in finance. Its value and the ways to calculate a risk premium for the market is a widely debated subject. This thesis examines numerous ways of calculating a risk premium for the Swedish market with regard to how good an estimation they make of a real risk premium. Estimations based on historical periods ranging from 20 to 85 years is calculated as well as a premium based on forward-looking estimates. The real risk premium is solved out for a selection of companies and an index with the help of CAPM.

Managing credit risk might be the single most important business area for any commercial bank. The assessment of "good" and "bad" corporate clients is a important task for a creditor. A bad debtor is a corporate client with hardships in meeting the continous claims (interest payments) that a creditor requires. One way of evaluating or separating a "bad" client from a "good" client is to assess the propensity for the client to file for bankruptcy. This thesis examines 226 firms in the Swedsh market in the quest of predicting corporate bankruptcy.

This paper studies how peer assessment is used as a strategy to improve young learners' results in Swedish as a school subject. Nine teachers are interviewed about their use of the method on 7-12-year-old pupils. Comparisons are made between the interviews and Swedish and international discussion on peer assessment. There are similarities between the practice of the teachers and what is said in the litterature about the method and its advantages and drawbacks. The teachers tend to emphasize the social aspects more, though.

Österbyverken is an industrial estate in Östhammars municipality in Uppland, Sweden. Many different activities have taken place on the estate the last 600 years. During the last 15 years both health and environmental studies have been made by different companies. At the most recent study a great increase of metals in Nerån, a river that runs partly through and partly next to the estate, was identified with mass balances. The purpose of this thesis is to accomplish a deepened study about the reasons for the increase of metals in Nerån.
