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.

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.

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.

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.

The aim was to identify if the veterinary nurse is as competent as the veterinaian in placing a nasoesophageal feeding tube. The aim was also to identify the complications with malnutrition and the advantage and disadvantage of the procedure. This essay is based on several interviews with both veterinary nurses and veterinaries. 16 persons were asked 4 short questions in conjunction with an intensive care/emergency and surgery congress in Gothenburg in February 2013. In addition 4 major hospitals that provided intensive care were asked to answer 5 more detailed questions, one answer from a veterinary and one answer from a veterinary nurse was requested.

The Swedish dairy production today consists of big farms and different housing systems are in use. These systems put demands on the cows? ability to cope with the environment and one challenge is the claw health in the herds. Some claw lesions that are frequently observed are foot rot, hemorrhages, digital dermatitis and sole ulcers, which can be caused by, for example, the claws? environment and the flooring type used.

Never before have so many moved so frequently as now. Mobility lies at the centre for the concern ofstates, business and technological development. Some even claim that we are witnessing a mobility turn inthe social sciences. However, as the capacity to move has increased so too has the control and surveillanceof mobility become more extensive. Since September 11, 2001 security has been the defining paradigm fora variety for actors.

In Örebro, the car traffic share does not tend to decrease. The crowdedness on some of the bus routes is high at times. Investigations show that the residents of Örebro want a city centre whose street environment is more restrictive of car traffic and better for pedestrians, cyclists and public transport. To decrease the car traffic share a rapid, convenient, clear, effective and environmental friendly public transport with high frequency and strong capacity in a short, direct and logical network is needed. A modern tramway fulfils these criteria.At first, this report describes factors that are important to take into consideration when planning a tramway.

Bakgrund: Perifer venkateter (PVK) är en allmän och rutinmässig åtgärd inom hälso- och sjukvården för att kunna lindra, bota och behandla genom att tillföra infusioner, läkemedel eller för att hålla en fri venväg. PVK består av ett främmande material som i kontakt med blod kan leda till att komplikationer som tromboflebiter bildas. Vid minsta tecken på rodnad, ömhet, svullnad, tromboflebit eller extravasation ska PVK avlägsnas. Syfte: Studiens syfte var att beskriva de senaste forskningsrönen kring sjuksköterskans omvårdnadsåtgärder för att undvika PVK-relaterade komplikationer. Metod: Studien är en litteraturstudie där resultatet baserats på kvantitativa och kvalitativa artiklar.
