In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

Companies that are facing the global market are put in to new challenges in order to streamline its business. One industry that has realized that changes are necessary is the construction industry, it is an industry witch is far behind the development of introducing information technology-tools systems in there business. It has shown there is a relation between high IT usage and high productivity, which is one of the reasons to why companies in the construction industry should purchase a business system especially for procurement. However, companies that have purchased a business system are facing difficulties in having their employees using it for its purpose. People react differently to changes and that?s why variations in quantities exist for usage of information technology-tools.

Business valuation is something that has been more general and discussion around this subject is very common. The discussions often revolve the various principles and procedures that a business appraiser can apply when a valuation of a business should be done. When there are different evaluation methods there are also resulting in an assumption that there are not so easy to create a complete objective business value. The individual evaluator choice of method will determine the result of the business value. The global world for each business has been more uncertain and turbulent/changeable which have tended to exacerbate the work for the evaluator to determine a business value.

Syftet med denna studie var att undersöka vilka samband det finns mellan värderingar, föreställningar och normer kring miljön till agerande för ekologisk hållbarhet i det vardagliga livet. Vår hypotes var att det finns samband mellan affekter kring miljöns framtid och agerande till hållbar utveckling. För att söka svar på syftet och bekräfta hypotesen har enkäter med frågor gällande individens värderingar, föreställningar och normer om miljön samt frågor om miljömässigt agerande skickats ut via e-post till 119 deltagare i åldern 23-65 år. Svarsfrekvensen var på 59 procent. Resultatet visade att det fanns ett flertal starka samband mellan miljömässiga värderingar, föreställningar och normer till individens agerande och hypotesen om att det fanns samband mellan affekter och agerande för hållbar utveckling verifierades.

Language impairment affects the ability to communicate. Children with languageimpairment have difficulties in using language in interaction to various degrees, and the contributions of the conversational partner are of great importance. The use of languagein interaction can be analysed by means of conversation analysis. The purpose of thepresent study was to study interaction of a group of pre-school children with language impairment with four different conversational partners. These were a peer with languag eimpairment, a peer with typical language development, a pre-school teacher and a parent.

ABSTRACTChlamydia and Chlamydophila are species of a family of bacteria (Chlamydiaceae) that cause a range of diseases, including conjunctivitis, in a variety of animals including pigs and humans. Some species cause zoonotic disease. This study examined the occurrence of Chlamydiaceae in samples taken from the lower eyelid conjunctiva in pigs with and without conjunctivitis. The study was initiated based on a herd investigation aimed to examine the experienced increase of conjunctivitis in some finisher herds. This study was conducted as a case-control study, by collecting samples from 62 case pigs (16-26 weeks old) and an equal number of controls, from three herds in Uppland, Sweden.

At the beginning of the 21st century, youth unemployment is paid attention to by the Swedish government and media. A grand part of the unemployed youth live at their parents´ house because of economic reasons contrary to their primary goal to be able to make their own living. It can be argued that the young unemployed´ s social citizenship is inferior to working citizens´ social citizenship. The thesis will not deal with suggestions on practical solutions, but rather seek for theoretical answers to whether the responsibility for the young people referred to should be a responsibility of the State or of the family. Communitarianism is a relatively young theory which is interesting for this thesis because it sheds light on the dichotomy individual - community.

I strävan efter att utveckla sin praktik har en grupp pedagoger filmat en vardagshändelse med eleverna i avsikt att belysa en fråga de är intresserade av att få svar på. Under ett reflekterande samtal undersöker de gemensamt det inspelade materialet.Studie syftade till att få svar på hur de tog sig an uppgiften, vad de fick syn på och hur de samtalade kring det de såg. Samtalet kan ses som ett vävande där olika pedagogers perspektiv möts. Studien sökte svar på vilka inslag som fanns i samtalsväven. Genom att synliggöra detta ville studien ge en ökad förståelse för hur skolledare och pedagoger kan skapa förutsättningar för att reflekterande samtal ska kunna bli ett funktionellt redskap i såväl professionell utveckling som verksamhetsutveckling.Forskningsfråga: Hur använder pedagogerna sig av reflekterande samtal när de utgår från autentiska situationer från praktiken?Resultatet visade att den dialogiska samtalsväven omfattade fyra typer av inslag.

The Purpose of this essay is to seek an answer to whether or not a conflict exists between priests of the Assyrian Church, the Syrian Orthodox Church and the Coptic Church in contemporary Swedish society, as well as to examine the environment between the three. The theological dissimilarities will be studied (from a historical standpoint), along with the interviewed participants views on the division in Christianity which will be presented also. I choose to interview six priests/chorbishops who live and work in Sweden, and the result was analyzed according to the senior professor of peace- and conflict, Peter Wallensteen?s theories on conflict and conflict resolution, where important issues are laid out to identify the core problem, and theological differences are discussed and compared from a union perspective.The result of the interviews illustrate a clear response that the participants experience a lack of functioning collaborations (from the Assyrians Church view, a collaboration is absent from the Syrian Orthodox Church and the Coptic Church, and vice versa) and most of the participants experience negative consequences from the divide in churches, as they strive for unity in Christianity as a whole. The theological differences between the churches proves not to be as significant as expected, the actual predicament lies partly in language-and phrase division along with a general rejection of each other?s interpretations.

The aim of this study was to analyse ninth graders self reported screen based activities, sedentary time and musculoskeletal symptoms and pain intensity. The other aim was to examine changes regarding musculoskeletal pain and inactivity between ninth graders from a cross sectional study in year 2004. To meet this aim, following questions were designed: How is the relationship between screen based activities, inactivity, musculoskeletal symptoms, pain intensity and differences between girls and boys? How have musculoskeletal symptoms and screen time changed since year 2004?Method: The method used for this study was a quantitative method. The research was carried out using a questionnaire that was answered by pupils from 11 schools from all over Sweden.

The background of the study consists of the fact that knowledge about how eating disorders are developed and maintained is extensive. Socio-cultural factors and media influence when developing an eating disorder is of significance. When reviewing literature and previous research, knowledge about practical attainments when treating eating disorders are insufficient. The aim of the study was therefore to examine how staff who treats eating disordered patients think about body ideals, strive for success and media influence in treatment and rehabilitation. The theory consists of Foucault?s theory of power, how beauty ideals are dependent of the cultural context in which we live and what qualities are associated with beauty and body ideals.

Many of us have grown up hearing or using words meant as insults or negative adjectives that were in fact names for social groups. Most of them have gone unquestioned in the mainstream consciousness, but the term Gay in the generally negative meaning has in the past years been given attention as offensive and homophobic, with debates emerging in response over whether or not this is true, particularly on the internet. It is the articles and forum threads from these debates that make out the empirical material for a qualitative study as I ask what these people?s thoughts are about this term and how it is perceived.After a qualitative coding and analysis of these texts, and interpretation of the results based on Erving Goffman?s theory of Phantom acceptance and stigma terms, Judith Butler?s theory of performativity, Ferdinand de Sassure?s theory of signifier and signified and how it connects to the community and Baudrillards theory of simulacra, this is the principal conclusion that I have drawn:For some of the people in this debate, the term Gay and its use is about homophobia and heterosexism, though mostly it?s not overt but a subconscious part of the continued dehumanization and stigmatization of homo- and bisexual people. This is a position I callThe socially focused skepticism.

Purpose.The purpose of this essay was formulated as to examine the relationship between the development of deaths caused by unintentional injury and fast economic development in a country. The purpose is to create a picture of the development in the chosen countries.Background.Injuries and the deaths that sometimes follow are a problem for all communities, if nothing else just because of costs and the absence of incomes for the state. Countries ability to restrain these deaths should be of interest. Studies show that the number of deaths causedby unintentional injuries correlates inversely with the GDP/c, we can therefore expect that better economic conditions leads to fewer deaths and vice versa. It has been shown that an economic crisis often leads to considerably higher death rates.
