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.

In an attempt to prevent ground damage and to reduce harvesting costs, StoraEnso's districts Värmbodal and Fryken, selected a number of final felling areas where the base roads have been marked by planners in the districts. The parties involved in the experiment are mainly planners, harvester operators and forwarder operators. The purpose of this paper is to determine the findings of this trial and to find cost savings or lost revenue. This has been done with a sample of interviews from the involved parties who logged the chosen felling areas. Literature about the interview process has been used to facilitate data collection, interpretation and analysis of the material. If we look at profitability based on assumed income and expenditure, revenue per MWh would be 63 SEK.

Goods that children come in contact with on a daily basis for example toys, electronics, textiles, household items, have attracted an increased attention in recent years because of a common occurrence of residues of potentially hazardous chemical substances. Some municipalities in Stockholm have developed plans for managing chemical risks and work systematically to phase out products containing hazardous substances. This thesis aims to contribute to an improved knowledge base for any future work with non-toxic nursery schools in Haninge. The study's focus is on the challenges encountered by conditions and problems of preschool personnel to manage chemical risks in early childhood environments. Primary data was collected through a qualitative approach based on semi-structured interviews with both the preschool staff and practitioners working in the central organization of the municipality.

This degree project is based on identifying and allocation of costs in a packaging section at Electrolux Distriparts in Torsvik.The purpose of this thesis is to identify the costs that emerge when packaging different articles and show how the costs are allocated. The report also contains improvement suggestions about how the company can use the current computer system more efficient.The methods that have been used in order to approach the problem and the collection of information have mainly been literature study, interviews and observation.The work started with answering the questions; which expenditure cost and direct cost exist in the section, how can they be allocated, if improvement can be done and how the flow of information is supposed to happen.In order to answer the questions we used our former experience and the knowledge we achieved by reading literature, interview relevant persons in the company and observations carried out in the section.Through our studies, we came up with an Excel file, which is the groundwork for a template that can be used by the company in different occasions depending on the situation and need. It is important to remember to modify the template if the presumptions change. In the template, we have identified the different kind of costs that emerge when packaging different articles and we have also allocated the costs. In addition formulas and estimations that are necessary for the cost calculation are presented.The work consisted in making the groundwork for a template.

The purpose for this Masters thesis is to describe childrens librarians work in supplying literature to children with emphasis on easy-reader materials. Our main questions are: · What do librarians believe characterizes an easy-reader book, and what do they base their decision on when classifying a book as easy-to-read? · How have the libraries in our study solved the hands-on difficulties associated with easy readers childrens literature? · Which factors do librarians consider to be important when supplying literature to children that are not used to reading or are not good readers? The theories we have used are Aidan Chambers Reading Circle and Karner Smidts view on the librarians professional roles when supplying literature. We have used a case study method, which means that we have gathered information through observation, objective papers and interviews. This has been done at six libraries.

Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

Oestrus in dairy cattle has changed over the last decades; the intensity of oestrus has declined and the duration decreased. Several studies have shown that not all dairy cows stand to be mounted, and that oestrus expression in many cases may be characterized by other behaviours. The aim of this study was to investigate oestrus behaviour in a herd of todays? high producing dairy cattle. The study was carried out at Jälla naturbruksgymnasium in Uppsala during one week in January 2011.

Bakgrund: Att förebygga, bedöma och behandla smärta är centralt i anestesisjuksköterskans arbete. Barns upplevelser och uttryckssätt vid smärta skiljer sig mycket från vuxnas. Det är därför en stor utmaning för anestesisjuksköterskor att tolka barns uttryck och känslor för att förstå barnet och kunna erbjuda trygghet och smärtlindring. Forskning har visat att barns postoperativa smärta underbehandlas, trots att kunskaperna om barns smärta ökat. Genom att belysa anestesisjuksköterskans upplevelser kan förståelsen för vad som bidrar till en god respektive mindre god postoperativ smärtlindring av barn öka.Syfte: Syftet med denna studie var att beskriva anestesisjuksköterskors erfarenheter i samband med postoperativ smärtlindring av barn.Metod: Semistrukturerade intervjuer genomfördes med åtta anestesisjuksköterskor från ett svenskt länssjukhus i mellersta Norrland.  Insamlad data analyserades med manifest innehållsanalys.Resultat: Utifrån analysen framkom tre kategorier och sju subkategorier.

Bakgrund: Mäns våld mot kvinnor förekommer i hela världen. För att upptäcka de kvinnor som blir utsatta för våld är det viktigt att våga ställa frågan om våld till kvinnor som söker vård. Syfte Syftet med denna studie var att undersöka sjuksköterskors upplevelser och erfarenheter kring att ställa frågan om våld till kvinnor som söker vård på en akutmottagning. Metod: Denna studie hade en deskriptiv design med kvalitativ ansats. Semistrukturerade intervjuer utfördes med åtta sjuksköterskor på en akutmottagning i mellansverige.Resultat: Sjuksköterskorna på akutmottagningen kände överlag att de inte hade tillräckligt med utbildning och beredskap för känna sig trygga med att ställa frågan om våld till kvinnor som söker vård.

The present memorandum outlines the structure, theoretical starting points and disposition of a thesis about the activities of Finnish immigrants in a Swedish local community, more specifically their political integration. The intention is to study the municipality of Katrineholm in the years 1944 to 1991.Previous research about the actorship of immigrants in spheres such as politics, labour unions, immigrant associations, educational associations and mass-education, as well as churches and religion, is presented to give an overview of possible areas connected to political integration that can be studied. The overview of previous research also covers local immigrant politics.The intended theoretical starting points for the proposed thesis are political economy and hegemony. The latter is intended to be investigated through its expression in the social relations class, gender, ethnicity, nationality and generation. It is suggested in this memorandum that hegemonies and social relations within a local political economy can be operationalised fruitfully in a study of political integration.

The purpose of this Master's thesis is to make suggestions as to how librarians can promote young reluctant readers to help them find the joy of reading. We want to show how the comprehension of these children and adolescents can be translated into action in the librarians work with reading promotion.Our main questions are:? What attitudes do the librarians find that children and adolescents, ages 9-15 with reluctance to read, have towards reading?? What do public- and school librarians do to stimulate children and adolescents, ages 9-15 that are reluctant to read, to feel the joy of reading?? What role or which roles can the public- and school librarians have in the work of reading promotion, targeting children and adolescents with a reluctance to read?We have used Beers's theories about reluctant readers and reading promotion, Chambers's model and theory ?Reading Circle? and his theories about conditions that promote a ?good reading environment?. We have also used Smidt's theories about the librarian's different roles in the work of supplying literature.The method we have used is qualitative and based on literature and interviews with 7 children- and school librarians that all of whom work or have worked with reading promotion for children and adolescents in the ages between 9-15, that are reluctant to read.Our results show that in order to gain understanding about the attitudes towards, and relationship to reading, our targeted group have, the librarian has to be aware of the inner conditions that these children and adolescents have. These inner conditions are going to affect the work and the result of the reading promotion activity.

Background: Domestic violence is a major social problem both nationally and internationally. Around the world 35% of the women say that they have experienced physical and/or sexual violence. In most cases it is the woman's partner who subjected her to violence. Every year, 12,000 -14,000 women in Sweden seek medical help as a result of injury incurred of domestic violence. The healthcare in Sweden has a responsibility when it comes to detecting, treating and documenting, but also to prevent violence and its consequences.Aim: To examine the extent to which nurses and midwives asking women about domestic violence, barriers for asking the question and making visible steps to increase the ability to ask the question.Method: A literature review, were included articles reviewed and quality determined.

Digitala spel har utvecklats kraftigt de senaste 10 åren. Moderna spel kan skryta med otroliga världar med trovärdiga karaktären och visuella egenskaper som liknar modern film. Modern teknologi har förmågan att skapa världar som kan uppsluka vår uppmärksamhet som aldrig förut. Många moderna spel lägger även stort fokus på att skapa ett narrativ som ger kontext och mening till den virituella världen. Ett sätt att skapa narrativ i spel har varit att implementera en bakgrundshistoria som spelaren får ta del av innan man börjar interagera med spelet.Målet med denna rapport har varit att koppla teorier om the magic circle till teorier om perception, och immersion för att försöka få en bild över hur spelarna upplever spelvärlden.

Syftet med denna studie är att undersöka hur textila modeföretag kan använda sociala medier. Vi frågar oss också hur företagen ska använda medierna för att få en närmre relation med kunder och hur sociala medier kan skada och stärka textila modeföretag. Vi gör en studie på hur textila modeföretag ska lyckas skapa närmre relationer utanför sociala medier och går in på budskap, word of mouth och lite om mediekanaler för att sedan se hur detta kan appliceras till sociala medier. För att få svar på vårt problem kände vi att det var viktigt att undersöka textila modeföretags syn på sin närvaro i sociala medier. För att göra detta valde vi att göra en kvalitativ studie med fyra företag; Monki, Rut & Circle, Shelta och Blue Jeans Company.

Vaccination of fish can be assumed to cause pain. This study was designed to see if we can minimize the suffering of fish following vaccination. Fishes are cold-blooded animals and thus more primitive than warm-blooded animals. Despite this, many organs, e.g. the nervous system, have the same basic structure as that of other vertebrates. The fibre system for conducting pain is more diffuse than in humans.
