In this study potential health risks for employees in connection with handling of bottom ash and bottom ash water at a Municipal Waste Incineration (MWI) plant have been investigated. Air surrounding the bottom ash and the bottom ash water has been examined. MWI is one of the primary ways to manage solid household waste, and bottom ash is the main solid residue produced by the incineration process. Bottom ash constitutes about 15-20% of the original waste. The bottom ash is extinguished in a water bath (bottom ash water).The study was carried out in a MWI plant in Karlstad, Sweden.

The main purpose of this study was to determine the impact of bedding material on the faecal microflora of horses. Another objective was to investigate the hygienic and physical qualities of the bedding materials used and how these may change in the course of the trial period. The bedding materials used were sphagnum peat and wood shavings. Six horses had each material as bedding for a three week period in a change?over experiment.

An increased use of social media has enabled a new arena for HR functions and the work with HR issues. Proponents are critical of this, as it can lead to ethical and legal dilemmas. So far the research on this area is limited. On this basis I found it interesting to study how social media is used in connection with the recruitment process. Those who will benefit from this study are primarily those dealing with recruitment, but also others working with HR issues.

The European Union is a 60 year long collaboration between the European countries. It was born from the intention to ease trade and thereby reassure peace. Within the 60 years EU has functioned it has developed and expanded further. In 1952 it evolved around the trade of coal and steel between six countries, today it includes 27 nations and oversees a large number of topics such as foreign affairs, a common currency and regional politics. EU has grown at several times, the latest expansion was the largest where 12 new countries became members. The unions of countries that only 60 years ago were at different sides of a world war can be considered an accomplishment.

In this paper Swedish hedge funds and strategies are discussed and analysed. These new financial forms seem to draw recently a huge attention both in media, press and the academic world. The fact is that hedge funds have existed already for a long time but it is still known too little about them. After the introduction of hedge funds, different asset pricing models are discussed including the most basic of all ? CAPM and further Fama and French three factor model as well as the expanding model with conditioning approach.

Tidigare forskning har visat att systematisk självrapportering är en fördelaktig metod för att följa enpersons psykiska mående över tid, och att en digital mätmetod i sin tur skulle innebära många praktiskafördelar jämfört med en analog. Detta är en experimentell randomiserad, kontrollerad studie som medutgångspunkt i personcentrerad vård och spelifiering undersöker 35 personers användarfrekvens ochattityder efter en tvåveckorsperiod där hälften har fått prova att självskatta sitt psykiska mående via enmobilapplikation, och hälften fått göra detsamma via ett analogt stämningsformulär. Resultatet visar enhögre användarfrekvens bland deltagarna i mobilapplikationsgruppen, samt ett uttalat intresse hosbägge grupper för digitala metoder för självskattning av psykiskt mående. Bägge metoderna ansesstärka personcentrerad omvårdnad. The aim of this study is to explore user frequency and attitudes for persons using a mobile applicationfor assessing mental health compared to persons using an analogue assessment method.

One step towards a more sustainable energy system is to create a more flexible electrical grid, where increased demand response among electricity consumers can play an important role. A distribution grid owner can encourage their customers to use electricity more evenly distributed during the day by introducing different types of grid fees such as time-differentiated power tariffs. In this master thesis, the theoretical economic impact of a flattened load profile for a distribution grid owner is investigated. Different factors that impact the distribution grid owner?s economy are identified and two are chosen to be quantified; losses in the grid and the fee to the feeding grid.

This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.

Swedish childcare has undergone radical changes in the last 15 to 20 years. It has evolved from kindergarten to pre-school, in other words, gone from simple childcare to an active learning environment with the child as the center. Official documents, such as the pre-school curriculum and other guide documents, define the role and work ethics of the pre-school teacher. In my thesis I argue that it is essential to have an ongoing and continuous discussion at pre-schools on the practical applications of these frameworks and ambitious goals.What do you do when you simply cannot give every child the individual time they should have according to rules and regulations? How do you stay an active and present pedagogue in today?s pre-school with large classes and heavy workloads? How do you establish a common professional work ethics within a pre-school so that all children are treated equally? In my scientific essay, I examine these issues based on a real-life situation: Ellen in the hallway.A pedagogue must continuously make balanced decisions based on rules and regulations, on life- and work experience which, in many cases, contradict each other.

Natura 2000 is part of the European Union: s framework to protect and preserve biological diversity. Natura 2000- areas are by the goverment appointed to areas of national interest for preserving nature. Also wind power stations are appointed as of national interest and the reason for this is the goverments goal to get energy from reneweble energysources. This essay describes when both these intrests conflict eachother when it comes to building wind power stations within Natura 2000- areas. The main focus of this essay is a casestudy of two cases from two different counties, Dalarna- and Norrbotten county, where applications have been made to build wind power stations within existing Natura 2000- ares, both cases have reached the court dealing with enviromental issues.

The purpose of this project is to examine students' pespectives on quality in teaching. The characteristics that are described to denote a 'good' and 'less good' teachers are linked to ideas about types of corresponding leadership styles in the classroom. The report is based on surveys of students in Upplands-Bro high school outside Stockholm. In order to get better insight and further knowledge of the subject, the student accounts have been related to current discussions in the literature about good leadership and teaching quality.Following the methodology of grounded theory a pilot study was constructed to design the research instruments. In the pilot study I collected students' perceptions on quality-related categories in teaching and leadership which then formed a bases for a survey which was distributed to a larger student sample. The survey includes questions that relate to the middle order, which is based on three criteria that make up the characteristics of a 'good'/ 'less good' teacher and the leadership style that suits students descriptions of good teacher characteristics.The results of the study show that a good teacher should have subject knowledge, be good at writing and illustrating the curriculum on the whiteboard and explain and clarify their instruction through good communication.

This thesis is based on a qualitative study on four different preschools in Sweden of which two are monolingual and two are multilingual. The purpose has been to study and compare literacy practices initiated by preschool teachers in mono- and multilingual preschools to examine how the preschool teachers themselves discuss on this topic.The theoretical framework of the study draws upon a socio-cultural theory based on literacy with an emergent literacy perspective in focus. The empirical material has been collected through observations and interviews. We are two authors on this study and the result is distributed in two case studies which are divided on the mono ? and multilingual preschools.

The purpose of this study was to examine customer attitudes towards flagship stores and how they perceive them. To ascertain this, and obtain answers to the research questions covering the study's main issues, we decided to turn to the customers who recently visited a flagship store.Our background theory is based upon literature from previous research done on the subject in the form of scientific articles and books. We present the theoretical concept that explains how flagship stores are used as a marketing tool and what impact they have on the new market. These will be helpful in answering our questions when we evaluate our results.!A theoretical framework, consisting of three value dimensions, was used as a support throughout the implementation of the study. These three values; hedonic, practical and social, should give us a better idea of what customers experience and what they value when they visit the flagship stores.!The method used in our investigation is of quantitative form, so that it can be feasible on a large crowd to thus contribute to a quantitative result.

AimThe purpose with our study has been to investigate if upper secondary high schools in the south of Sweden, Stockholm and north of Sweden follow the outdoor education regulations stated in the curriculum (Lpf-94). Moreover, we aim to study if the teachers? previous experiences as well as the students affect the outdoor education. Finally, the purpose is to find out how the outdoor-life-education can be improved. These are the research questions:o How do the chosen high schools follow the outdoor education regulations stated in Lpf-94?o What obstacles, advantages and differences exist between the outdoor-life-education in these high schools?o In what way do the teachers? outdoor life experiences influence their education at school?o How can the students influence the outdoor education in their High Schools?o How can outdoor education be improved?MethodThe study is based upon data collected from four interviews with PE ( physical education) teachers from four different high schools.

Nano materials can today be found in a wide range of consumer products and the number of new products on the market is expected to inrease. In the shadow of hope for nano materilas potential in various applications, low awareness of its health and environmental risks is hiding. Furthermore, the knowledge about people´s risk perception of nano materials is limited. Parallel to the situation described above, the scholls meet the challenge of incrasing the scientific literacy. To achieve this goal, skills in argumentation in science studies has been emphasized and the concept of socio-scientific issues has been emerged.
