This thesis analyses how a radiology department at the largest hospital in Sweden, Karolinska University Hospital, most profitably could expand its capacity for investigating cancer patients using magnetic resonance imaging (MRI). The queues today for patients waiting to be scanned are long, which delays the start of cancer treatments. Meanwhile the hospital has a budget deficit of half a billion SEK, which make any expansion hard. In this thesis we evaluate the alternatives of investing in new machinery; utilize the current machinery better by using them more days annually or through a shift work system. Finally we evaluate a combination of these.

Husums plant has a selection of different pulp pumps at bleaching plant 4 and 5. The displacement- (HC-pump, Sund Defibrator PTD-60) and centrifugalpumps (MC-pump, MCA 42-200, MCP 30/20) are of interest in this report. The centrifugal pumps are controlled by throttle valves, which result in an energy loss. Chemical mixers are used to mix ClO2 into the pulp before proceeding into a holding tower where the bleaching process occurs.The energy demand of the different positions has been measured or calculated to be used in comparisons against new equipment. Quotations were requested and delivered from Valmet and Sulzer.

Husqvarna is a world leading producer of chainsaws with a well-established brand name. Husqvarna now has an interest in investigating the possibiltiy to expand their production of chains and guide bars to include cutting equipment for timber-harvesters.This project is a technical study which aims to answer questions about cutting equipment for timber-harvesters that have been decided in cooperation with Husqvarna. The questions have mainly been focused on forces, cutting speeds, service and maintenance -as well as general questions regarding the size of the Swedish market.Two methods have been applied to answer the questions. Interviews with retailers of harvesters, producers of harvester heads and harvester drivers.The main findings in this project show that there is a relatively small selection of harvester chains on the Swedish market. In contrast to the selection of harvester chains the selection of guide bars is quite large.

The mouse (Mus musculus) is the most commonly used mammal in biomedical research and can easily be restrained by both hand and by a device. Restraining animals causes stress that not only decreases the animal?s wellbeing, but may also influence the research results. The first aim of this study was to train mice to voluntarily stand still using positive reinforcement training. Another benefit of teaching a mouse to stand still is that you can avoid anaesthesia for some procedures.

The aim of the study has been to investigate physiotherapists? view on a new method of treatment in physiotherapy.

The study was carried out as a qualitative content analysis study.

This degree thesis is based on an assignment from BEOMAT in Storfors. BEOMAT is a company that constructs and sellsclay pigeons to both the national and international market.Our main purpose with this paper is to find a solution/system that can replace the expensive and space demandingOlympic trap facility. Our solution will replace fifteen clay pigeon throwers with one automatic thrower whosimulate all throwers together. The system will be provided with an appropriate control system for mass productiontherefore this system needs to be user-friendly so no previous knowledge is required.Totally 405 different throw coordinates will be stored in the programme in nine different subprograms. According tothe Olympic-rules the throwers should coincidence within certain specified conditions, this will be solved with anrandomizer in the programme.

As a result of global competition, companies within the automotive industry are required to improve their production systems to achieve sustainable and competitive production. To attain operational excellence, companies have adopted concepts like lean and World Class Manufacturing (WCM).In order to deliver, companies need to increase the availability and reliability of production equipment. This demands focus on both operational and strategic maintenance, and efficient equipment acquisition and management. The main objective of this thesis is to identify processes and success factors that are necessary for improved maintenance performance. By conducting a case study and by performing a literature review, the following has been studied: 1) how companies within the automotive industry work with maintenance and maintenance strategies, 2) implementation of maintenance strategies, and 3) new acquisition and spare parts management for maintenance. The results show that basic maintenance concepts and related terms are well defined in the literature.

Background:The definition of mental illness is characterized by a lack of management regarding mood, thoughts or behavior. It is difficult for the person to cope with everyday duties as well as relationships with other people.The study revealed that the society should take action to prevent social isolation for those with mental illness. The central concepts of care theory is love, learning and well-being, where nurses' conditions and actions create results in the patient.Aim:Describe skills and prerequisites nurses need at the meeting of patients with mental illness. A further aim was to examine the ethical considerations included studies made use of.Method:A descriptive literature studyMain result:Nurses feel they do not have skills regarding mental illness. When nurses care for patients with mental illness are often formed stigmatizations regarding these patient groups and care will suffer.

Employee turnover can cost an organization a significant amount of money. In addition, retention of employees can beneficial towards to an organization as it e.g. allows to save costs related torecruitment and training of new employees. The fast food industry is recognized as an industry which employs low-skilled employees and is especially in the United States known to be prone to high employee turnover. With regards to Europe, only little information is available in the field of low-skilled employee retention in the fast food industry.

The purpose of this work is to explore and illuminate the circle times function and importance of preschool by the pedagogue perspective and the circle time design in relation to children's age group composition. The study questions are:What is the purpose of circle time in preschool educational activities according to the teacher and how does the teacher look at his own role?How do the teachers plan, design and perform the circle time of small children and big children's section? What similarities and differences exist?This is a qualitative study based on interviews with four preschool teachers and observations of their circle times. Research and theories showed that the circle time is a social training, provide a sense of community and is a ritual that gives a good daily rhythm.The results of the study demonstrate that the circle time is an important routine that occurs for a short time daily in early childhood education. The circle time organizes and structures the day for both children and staff group.

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

Arbetsplatsernas ständiga utveckling och förändring har lett fram till ökade psykosociala krav från de anställda som företaget måste bemöta. Ska man bedriva ett hälsofrämjande arbete bör hänsyn tas till hur kulturen ser ut på arbetsplatsen. Samlade värderingar och verklighetsuppfattningar kring hälsa skapas när individer samverkar med varandra och omvärlden, detta kallar vi ?hälsokultur?. Syftet med studien är att beskriva hur hälsokulturen ser ut på ett företag och vilka möjligheter och resurser som finns på företaget för att utveckla denna.

The use of technology in today's society is frequent and often necessary, but how, when and where are we supposed to learn how to use it? And if it is such a big and important part of our society, then why don?t teachers get more training in how to use the technology? The purpose of this paper is to examine whether teachers attitudes to technology affects their use of technology in their teaching. In school technology can be a complementary to other material, if teachers have the necessary skills to use technology in a pedagogical way. I have chosen to do a qualitative study in form of interviews and observations at a school outside of Stockholm. The results show that both school and teachers must want to work with technology if anyone will be getting something out of it.

Bakgrund: Fotboll är en sport som präglas av knäskador, muskelbristningar och stukningar. Mycket fokus ligger kring hur man på bästa sätt kan undvika och förebygga att ens främsta resurs, spelarna, undviker att bli skadade och på bästa sätt kan producera resultat för klubben de tillhör. Studier har visat på att skadeprevalens är något som ökar i och med en ökad träningsmängd och att många skador är en följd av både muskelsvaghet och fel sorts träning. Många av dessa undersökningar menar på att man i dagsläget tränar fel och att träningen mer måste fokuseras på de fysiska krav som ställs inom den idrott man utövar, i detta fall fotboll.Syfte: Syftet med denna undersökning har varit att se om det finns någon korrelation mellan typ av träning, träningsmängd och skadeprevalens inom herrfotboll.Metod: Studiens syfte har besvarats med hjälp av en strukturerad enkät som skickats ut via en web-länk till aktivt fotbollspelande män. Undersökningen har involverat 100 respondenter från olika divisioner.
