Sveriges ensamkommande barn. En studie av konstruktionen flyktingbarnet.

Children who have fled to Sweden, without their parents or guardians, have been a controversial subject during the winter of 2002. Their situations on refugeestations and the responsibiliy by community and the state have been discussed. My composition is about these children. The composition is not about the situations of the children - focus is instead on the people who operate with the children; community, state and organisations. I want to find empirical levels which show what the children associate with.

Orden bland drakar och demoner : En språkstudie av svenska rollspelsböcker

The purpose of this essay was to do a research about if the language in Swedish role-playing books is used correctly and if the composition along with the possible language errors makes the books hard to understand.This research was also about to find out why these problems occurs and if the authors are aware of them.I choose books from two Swedish role-playing games, Eon and Drakar och Demoner. I read them trough, noted the mistakes made and put them together in a scoring table. I also did a LIX-test on the books and interviewed one of the authors.The results shows that the books to Eon is harder to read than the books to Drakar och Demoner and this agrees with the vision the authors of the books claims to have.The results also shows that it is not only the language mistakes and the composition that makes the books hard to read, but also the choice of difficult words and badly formulated rules..

Gregorius : Bengt Ohlssons roman Gregorius i dialog med Hjalmar Söderbergs Doktor Glas

This thesis is about the interaction between composition, notation and interpretation and what occurs between the fields with an extended notation.The purpose of my thesis is to examine the possibilities tothoroughly describe and map the sounding samples through composition prototypes.The thesis has a qualitative approach, and the empirical material consists of different documents about notation and from interviews with musicians and students about the instruments used in the thesis.It also consists of 17 compositions recorded at Örebro University School of Music as an appendix.The analysis shows that the context in which the symbols are found, play an important role in performing them. It also shows that the performers are rooted in a traditional way of performing..

Sand pits as habitat for ground beetles (Carabidae) : does the area affect species number and composition?

Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.

Utveckling av en HBV/PULS-model med sammanfogade markfuktighets- och responsrutiner

Soil properties affect the Chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Total organic carbon (TOC) and chemical oxygen demand (COD) - Monitoring of organic pollutants in wastewater

Total organic carbon (TOC) and chemical oxygen demand (COD) are two methods used for measuring organic pollutants in wastewater. Both methods are widely used but the COD method results in production of hazardous wastes, including mercury.The purpose of this study was to validate the method TOC that will replace COD and find a factor to convert TOC to COD. In this study 26 samples were analyzed from four sewage treatment plant in the municipality of Enköping.The results show that the COD method could be replaced by the TOC method.The factor for COD/TOC was between 3.1 - 3.3. Both methods will be used in parallel until 2013 when it will be forbidden to use the COD analysis..

Utvärdering av Naturvårdsverkets bedömningsgrunder för makrofyter i sjöar

According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. The main focus of this thesis is to evaluate the efficiency of the assessment criteria for macrophytes. In addition the concordance between the ecological status classes of the four quality factors included was analysed.The assessment criteria for macrophytes are based on the total phosphorus preference of the respective species. The focus is thus mainly on the nutrient level of the investigated lakes and the environmental problem monitored is eutrophication.

Bach and Improvisation - A research on how useful Bach is for improvising music

I wrote this thesis for myself and someone who would like to learn improvised music not from Jazz but Bach. I analyzed one composition by Bach, then I showed one example of using his idea to a Jazz standard tune. It was challenging for me to understand and analyze his composition as a Jazz improviser. To be honest I don't like to learn the music language from Bebop music but I like to play Jazz standard music. If someone would like to be good at playing jazz music, I think that it is important to know the music language in jazz.

Is goat milk a better milk replacement to piglets, rat pups and foals than cow milk is?

AbstractOne opinion among people who are experienced in hand rearing newborn mammals is that goat milk is more suitable than cow milk if the young needs a milk replacer. The purpose of this literature review was to find out if there is scientific evidence that goat milk is a better milk replacer for piglets, rat pups and foals than cow milk. The milk is essential for the newborn animal, as its only source of nutrition until it has learned how to eat solid food. In this literature review, the composition of goat milk and cow milk is compared with the nutrient requirements after birth in piglets, rat pups and foals. The nutrient requirements and the milk composition are partly determined by the newborn mammals activity level and suckling frequency, which also is described.

Ombyggnation, från sågverkslokal till restaurang. antonio ziakoulis

Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.

Conqueror för Indigo

Conqueror for Indigo is production treated with an active chemical to maximize the ink adhesion.ArjoWiggins has found that another chemical, the candidate compound, would improve the propertiesof the paper. ArjoWiggins therefore wish to replace the current compound. To strengthenthe patent requirements for ink adhesion needs to be determined. A theory is developed to whychemicals with certain properties maximize the ink adhesion. Experiments are performed but theresults are inaccurate.

Karakterisering och klassificering av gotländska ytvatten enligt ramdirektivet för vatten

In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.

Styrelsens unika kompetensbehov : En studie av kompetensförändringen i styrelsen

Background: The board of directors is a key player in corporate governance. Their role is to ensure that the corporations are run with the interest of the shareholders as the main focus. In the beginning of the 21st century, a survey was made about the confidence of the Swedish business community and in which criticism was directed to the board of directors. The boards were deemed inadequate in their function and were often solely composed by members with similar experiences and competence, therefore lacking in diversity. In order to improve the competence and work of the board of directors, the Swedish code of corporate governance was introduced and its recommendations comprehend the boards? size and composition.

Järnets förekomst i grundvattnet i isälvsavlagringar i Dalarna : Bakgrundshalter och rörmaterialets inverkan vid grundvattenprovtagning

A study has been performed that investigates the variation of iron content in groundwater.The study was initiated by Midvatten AB, which noticed that the iron content in groundwater samples can vary greatly over small distances. The purpose of this study was to geochemically and geohydrologically determine the factors that influence the content of iron and manganese in groundwater from a selection of eskers in Dalarna, and determine how to best sample groundwater with the method used by Midvatten AB. An evaluation was made of how the vertical variation in soil material, water composition, pumping time and pipe material affects the content of iron in groundwater. Piper diagrams were used to study the relationship between the Chemical composition of the groundwater and the content of iron and manganese in groundwater samples from the studied areas. The groundwater from the studied areas was then classified in the Piper diagrams, according to the content of the major ions.

Valfrihetens konsekvenser : medvetna och omedvetna skolval

This study illuminates chosen parts of the present opportunities, in the Western World, for parents and children to choose which school the child will attend (freedom of choice), along with possible consequences that may follow. My research questions are: 1) Do tendencies show that freedom of choice leads to increased segregation, and if that is the case, how is it manifested and does it matter? 2) What relations between the student composition of schools and teachers' expectations and attitudes toward students are there? 3) Do the results from previous studies match with the result from my interviews? The methods used for answering the questions are literature studies and interviews made with six teachers who are working in two upper secondary schools in the northern part of Sweden, i.e. three from each school.The result shows that freedom of choice, regarding schools, seems to lead to student compositions that contribute to increased segregation in societies. It leads to more homogenous student compositions, in the form of ethnicity and social class, in schools in general, with consequences like different expectations and attitudes among teachers depending on the status of the composition.
