The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

The aim of this Master?s thesis is to explore the meaning of literature forliterate immigrants in regards to identity and integration. The study is based onqualitative interviews with eight Swedes of various backgrounds, but with thecommon experience of an immigration process. In addition to being migrants, therespondents are also public library users who have an interest in literature and whoread literature during their leisure time. To analyze the empirical material ananalytical framework, consisting of a number of analytical concepts from Libraryand Information Science, Literature Science, and Sociology, has been used.

Todays board game manuals have many shortcomings. One of them is that they are not always adapted to the game's target audience.Adapting the language and shape of a game manual for the the target group children, can save time for both parents and teachers, and give the children a chance to conquer the game by themselves. In addition, playing board games can lead to children developing other important properties such as problem solving and independence.This study found that the game manuals inconsistency, tone and the way they adress the reader makes it difficult for children to grasp the content. Many game manuals do not speak directly to the reader, and often describes gameplay in a passive way, which has been shown by this study.This study has resulted in 12 guidelines for writing game manuals for children. In addition, they have been tested with a sample study.

This essay examines how humor is used in the making of stereotypes in the Kronlöf sister?s video SÅ JÄVLA PK! In addition I give my analysis of how power and resistance is shown in the video. Through Michel Foucault?s conception power and resistance together with Judith Butler?s theories about performativity I?d like to show how the characters you can see in the video, in addition to the humor, also put themselves in a public context. I discuss my material in relation to a number of similar and current events that concern sexism and racism in Sweden.

A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.

The purpose of this qualitative study is to create an understanding for if and how nonverbal communication and the learned gender structure influence interactions during employment interviews for executive posts. The study is conducted from a social constructivist perspective where it is argued that the individual is created through social interactions. In order to obtain understanding for social gender structure and nonverbal communication in social interactions observation has been utilized as a method. In addition an observation matrix based on nonverbal behavior and masculine and feminine hexis has been established. The results include both the specific individual?s and the general interactions that took place during the employment interviews.

Syfte: Mitt syfte är att studera elevers, i år 3 och 4, uppfattning om symboler och begrepp, inom räknesätten addition och subtraktion. Jag vill framförallt ta reda på hur eleverna tolkar symbolerna +, - och =. Till min hjälp använde jag mig av diagnostiska prov. Metod: Jag valde en liten landsortsskola på Västkusten, studien omfattade 16 elever i år 3 och 4. De 16 eleverna delades in i 2 grupper, med 8 elever i vardera gruppen.

The aim of this work is to analyze if a change in the benthic community can be detected two years after a restoration of a small stream. The samples were taken in a small stream at Tinnerö Eklandskap just south of Linköping. In addition to the restored area, two reference sites upstream and downstream of the restored area were sampled to compare to the restored site. The method used for sampling of benthic fauna in the stream was kick sampling. ASPT, Berger-Parker and Renkonen-indices were used to find out if there was any difference between the reference areas and the restored area.

I have through qualitative interviews and analysis of previous research in the area searched answers to what tablets are used for in preschools and the reason why they are used in this way. In addition, it examines the similarities and differences there are in how teachers and children describe the use of the tool in preschool. The study is also looking for answers on whether and how the plates are used to develop children's scientific knowledge. There are six teachers and 14 children's statement that forms the basis for the analysis. The results indicate that tablets are used for two purposes.

The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.

Syftet med denna studie är att få ökad kunskap om vilka olika lösningstrategier elever i år 3 tillämpar när de löser ett matematiskt problem. Har eleverna utvecklingsbara strategier? Finns det elever som väljer strategier som ej är utvecklingsbara?Vi valde att använda oss av en kvalitativ undersökning där vi tolkade elevernas lösningar av två matematiska problem av varierande svårighetsgrad. Utifrån denna tolkning kunde vi dela upp lösningarna i olika lösningsstrategier som eleverna använde sig av. Undersökningen genomfördes på 89 elever på tre skolor i olika kommuner.

Syftet med denna studie är att synliggöra några elevers svårigheter när det gäller de centrala aspekterna i grundläggande taluppfattning, med fokus på addition och subtraktion. Studien grundar sig på 13 intervjuer med elever i årskurs 3-5. Som utgångsmaterial för intervjuerna användes den muntliga diagnosen Individuella samtal som ingår i Diagnostiska uppgifter i matematik för användning i de tidiga skolåren (Skolverket, 2010c). I samband med intervjuerna observerades även hur eleverna konkretiserar uppgifterna med stöd av sina fingrar och tiobasmaterial. Den muntliga diagnosen ger en tydlig bild av vilka strategier eleverna använder sig av när de löser en uppgift samt visar vilka svårigheter eleverna har när det gäller grundläggande taluppfattning.Studiens resultat visar att eleverna har svårigheter med den grundläggande taluppfattningen, dock i varierande grad.

The word mathematics is often associated to addition, subtraction, division or multiplication. This is not the kind of mathematics that belongs to pre-school. In my essay I have chosen to write about how mathematics is used in pre-school. In the literature it is written that the best way of becoming familiar with mathematics, is to integrate it in the every day life but that there are educators that use traditional mathematics education in pre-school. The questions I would like to answer are:1.

Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.
