Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.

Om man vill skapa ett realistiskt hav inom Computer Graphics är det viktigt att man har snygga övergångar till andra material. Ett exempel på detta är stränder och det är precis där fokusen på den här studien har legat. Studien gick ut på att hitta en enklare lösning på att visuellt förbättra stränder inom Computer Graphics. För att göra detta så testade två olika metoder i olika experiment. Den ena tekniken som testades var att simulera partiklar för att få fram en bättre strandlinje och de andra var att skapa en shader för att förbättra den.

The starting point of this thesis is the debate surrounding the two referenda?s in France and the Netherlands in May and June 2005, regarding the proposal of a European constitution. The aim of this study is to analyse how democratic legitimacy and the role of the citizens portrays within the democratic discourse of the European Union. The empirical material is based upon both speeches from the European Commission and news articles from the French newspaper Libération and the Swedish newspaper Dagens Nyheter. Discourse analysis is used as a theoretical frame of reference combined with models of democracy.

This essay is about gender equality in a Swedish upper secondary school. The aim is twofold: to obtain knowledge about feminism, gender equality, boys´ and girls´ situations in schools and gender equality work there; and to find out if government management documents for schools work effectively when it comes to promoting gender equality in schools. There are four research questions: How do teachers interpret what´s said in management documents for schools? What strategies do teachers use to promote gender equality? What opportunities and obstacles do teachers see for promoting gender equality at the specific school? And, finally, do the management documents for the school work effectively when it comes to promoting gender equality?The study has a socialist feminist perspective, which sees gender differences as a result of a mix of biological, historical and social factors. Important theoretical standpoints include gender socialization as an explanation for how girls and boys become women and men.The results of the study points out that teachers interpret management documents differently, and that they find the documents hard to understand.

The purpose of this report is to document the experiments carried out, methods used and results gained during research into how the silicon content of an aluminium alloy affects the coefficient of thermal expansion (CTE).The goal of this paper is to better understand and to find a relation between silicon content and the coefficient of thermal expansion.Experiments were carried out using carefully prepared samples of Al Si alloys (0, 7, 10 and 20% Si content). Using these alloys, the CTE could be measured using a dilatometer.Comparative analysis carried out could map the effects of silicon content on the coefficient of thermal expansion and an equation was created. Using simple graphs and the rule of mixture method, the authors were able to build a simple tool for calculating the CTE of specific aluminum silicon alloys..

The aim with this study is to through a research summary review experiences of growth and theparents caring ability among children who has grown up with parents having intellectual disabilites,and by empirical data illustrate how these persons today describe their childhood, their parentscaring ability and other cicumstances that have affected the growth. The results from the researchsummary are then to be compared with the results from the empirical data in purpose to reviewsimilarities and discrepancies.The study has a qualitative approach and it is based on foundings from earlier research andinterviews with four women whos mothers have intellectual disabilities.In the existing research of this issue there is a clear dichotomy between whether the researchershave focused on either the children or the parents. In both perspectives there are differentconceptions about whether a person with intellectual disabilities have the capacity to care for andraise a child, as there is about how the parents intellectual disaparment affects the child.The womens stories of the childhood are obviously unique, but they also have many experiencesin common, both among themselves as with what has been found in research. Children of parentswith intellectual disabilities have been classified as a risk group, wich has been shown by reversedroles for child and parent, lack of attachment to the parents and by insufficient care. Despite thedifficulties that the women have faced, they describe many parts of their lives in positive termstoday.There seems to be other influences in addition to the parents intellectual capacity that affect theesechildrens outcomes.

A pilot-study was used to investigate, types of assistance, assessed needs, outcomes and effects of special-needs assistance given to a subsample of compulsory school pupils in an effort to develop an evaluation strategy for identifying educational impacts of specific special-needs inputs.  Preliminary results indicate a tendency for postive outcomes for most pupils in the pilot group (n = 11) but also that many pupils have residual difficulties.  Pupils with residual difficulties mostly required special education asssitance with Maths, English or Swedish.  More pupils also needed support with behavioral difficulties.  More research and an expanding knowledge base is required in order to effectively evaluate outcomes of teacher support.  Schools need help in devising different methods of assistance and particularly for pupils with behavioral difficulties..

The main purpose of this study is to examine differences and similarities concerning teamwork and interactive skills among preschool children while they interact with an Ipad respective a number of selected traditional artifacts. The traditional artifacts chosen for this study are small Lego blocks, JovoToys (click and construct system) and large puzzles. The study takes its starting point on the basis of both a social- and a learning perspective when different groups of preschool children in the ages from three to five years interact in fellowship groups with respective artifact. Primarily the main focus is to examine differences and similarities that appear from without the social perspective.The overall objective is to identify what eventual differences and similarities can be found purposely on both what is happening in the social interaction between the preschool children themselves but also what is taking place in the interaction between the children and each artifact. This study will also via theoretical frameworks create an understanding why eventual differences and similarities exist.The results are based on both a literature review and a field study.

To assure good quality the software needs to be tested to find errors and to verify that the programme meets the customer?s expectations. Traditional methods are usually used in software development and means that a number of predetermined steps are followed. By using agile methods the development can more easily be adapted to the changes on the market. With these methods the testing is carried out continuously throughout the project.

Bakgrund: Gingivit kännetecknas av svullet/lättblödande och ibland ömt tandkött. Gingivit är en inflammatoriskt orsakad reaktion som uppkommer i samband med närvaro av bakterier. För att motverka utvecklingen av gingivit rekommenderas munhygienvård regelbundet. Gingivit kan utvecklas till parodontit med skador på upphängningsapparaten och benstödet, orsaken till detta är idag dock ej helt klarlagd. Kliniska variabler (blödning vid sondering) är vedertagna diagnostiska metoderna för diagnostisk av gingivit idag.
