ABSTRACT Behavioural problems are a compound conception for emotional difficulties at different levels. Individuals with behavioural problems could have difficulties with social relations, low self-esteem, anxiety and worry. The purpose with the examination was to describe how clients apprehend their behavioural problems and what they consider could be the causes of it. The examination was based on the qualitative interviews with 5 clients and a professional helper. We came in contact with our clients through our practice.

The purpose of this essay is to investigate which components previous scientific studies suggest that an efficient treatment for adolescents with behavioural problems should contain. For this purpose, an extensive review of scientific research conducted in Scandinavia has been read and will be presented in this essay. This essay also present an introduction to residential care in Sweden as well as to an alternative form of treatment for adolescents with behavioural problems called Multidimensional Treatment Foster Care (MTFC). The result of this essay suggest that treatment of adolescents with behavioural problems should be based on the emphasis of risk/resilience factors of the youth and that the treatment should be adapted to the youth?s individual personality and way of learning.

The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.

Syfte: Studiens syfte är att undersöka huruvida det går att prognostisera utveckling på OMXS30 med hjälp av lämpliga tekniska analysverktyg. Detta för att utreda hur relationen mellan den Effektiva Marknadshypotesen och Behavioural Finance ser ut på den svenska marknaden. Vidare är syftet även att undersöka möjligheten till att förbättra avkastningen med hjälp av tydliga restriktioner avseende money management. Detta undersöks för att klargöra om en högre avkastning kan erhållas med denna investeringsstrategi jämfört med passiva alternativt slumpmässiga investeringsstrategier. Metod: Tre tekniska analysindikatorer testas på svenska OMXS30 mellan åren 1987 och 2008.

Studien utreder fondförvaltares investeringsbeteende i förhållande till forskning om irrationellt beslutsfattande vid beslut som innefattar ett riskmoment. I studien har ett flertal fondförvaltare svarat på frågor som relaterar till forkning inom Behavioural Finance. Speciellt inriktat på Prospektteori och teorier om flockbeteende. Syftet är att identifierar eventuellt irrationellt investeringsbeteende hos fondförvaltare som i tidigare studier återfunnits hos privatsparare..

SECO Tools manufactures tool inserts for all types of metal cutting machining. (Ti,W)C is a common raw material used in the production. At arrival, the material (Ti,W)C is always analyzed. Titanium has previously been analysed with x-ray fluorescence spectrometry, but as the calibration has previously been performed with two different types of titanium (rutile and metallic titanium), the results has differed. Because of that, this thesis project has been devoted to analyze titanium, to find the best titanium compound for producing standards.The work has been performed using literature studies and many experiments in the laboratories at SECO Tools inFagersta,Sweden.

This Master?s thesis examines library courses, a relatively new form of user education. Our focus is on the pedagogical point-of-views reflected in the text in these library courses. The primary purpose of the study is to analyze the pedagogical discourse displayed in the library courses to determine if the perspective is behavioural, cognitive, constructive or socio cultural. We are investigating if the pedagogical discourse differs from course to course, and if so, how are they different? In addition we aim to find out how the pedagogical discourse in the library courses relates to university websites and governmental and legal texts, at the discursive and social practice level.

Communication is an important part of any multi-agent system. There are different ways of communicating and they have different effects on a multi-agent system. This project describes and evaluates two different ways of communication, implicit and explicit. To compare the two methods, two experiments have been executed. The result of the experiments have been compared and discussed.

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

In this study, 29 calves were dehorned by heat cauterisation at the age of 1 to 8 weeks. Before the procedure, the calves were given local anaesthetic but were not sedated. In connection with the dehorning, 14 calves were given the non-steroidal anti-inflammatory drug (NSAID) meloxicam and 15 calves were given placebo. During the following three days behavioural studies were performed to investigate if the different treatments had any effect on the calves´ postoperative behaviour. Head shakes, head rubs, kicks and ear flicks were studied, as earlier studies have shown that an increase in these behavioural patterns suggests postoperative pain.

This work is about presenting the weave in a new and different context, by bringing textile and glass together. The work is characterized by material and shape experiments with silver and copper weave and hand blown glass. From experiments and sketches, the work has resulted in four sculptures, symbolizing four selected stages in a lifecycle; the birth, the development, the maturity and the death. One important part of the work has been to combine different materials and techniques.Studies of literature, sketching, handweaving and integration of silver and copper weave in the glass have been important methods in the working process. Inspired by the flower, the human being and the universe, a story about the life cycle has taken shape.The paper describes the working process with choices and analyses.

The purpose with this thesis was to examine the cold rolling mill located at Högskolan Dalarna and to stabilize the rolling process, to achieve steady state. Experiments with cold rolling of an aluminium strip have given results for rolling force, friction, reduction, strip tension and strain hardening. Results show that steady state has been found for the experiments with roll force and strain hardening, and not been found for the experiments with friction and reduction. Results show that increased strip tension gives lower roll forces. The roll force equation of Stone shows comparable results with reality for dry contact with reductions up to 30 %, but starts being incomparable with higher reductions.

There is always an endeavor to govern the initial products in the plant cultivation with precision in order to keep down the expenditure and in order to decrease environmental impact. Initial phosphorus fertilizer can then be one possibility in order to keep down the fertilizer cost and to decrease environmental impact. This exam study includes a literature study about location of fertilizer and which effects this give and two field experiments. The aim with initial phosphorus fertilizer to autumn wheat is to accelerate the root growth and to give the crop a big root system before the growth stagnates before the winter. Easy to access phosphorus favours the root growth.

Sömnsvårigheter hos ungdomar är ett växande problem i Sverige men det saknas forskning om behandlingsmetoder för åldersgruppen. Syftet med studien var att testa kognitiv terapi med beteendeexperiment (KT-I) på gymnasieungdomar med primär insomni. Studien genomfördes enligt en Single Subject design med för- och eftermätning. Tre ungdomar i åldern 16-18 genomgick en sju veckor lång behandling efter 1-2 veckors baslinjemätning. Resultatet visade att svårighetsgrad av insomni minskade, att funktionsförmågan dagtid förbättrades och behandlingsmålen uppfylldes i hög grad.
