Stress in nurses' work needs to be studied in order to prevent stress and impaired quality of care. Aim: The aim of this study was to describe nurses' experience of occupational stress and factors that contribute to occupational stress. Method: The method used was a literature review. Results: The analysis resulted in five themes which describe nurses' experiences of occupational stress and factors that contribute to occupational stress.

Krav på redovisning och prestation: En studie om hur en insamlingsorganisation hanterar externa krav

Much attention has been directed to Charity Foundations and how they use the donations given to them. Donators and external organisations put pressure on and evaluate the performance of Charity Foundations. The purpose of this thesis is to increase the understanding of how Charity Foundations handle the pressure from external parties through a qualitative case study of one Swedish Charity Foundation. The most important external factors have been identified and the accountability relationships between each party and the Charity Foundation have been examined. The empirical material was collected through semi-structured interviews and from written sources.

Utveckling av 22 : -en motkolvs HCCI motor

Environment friendly transports are one of the main topics in the industry and society today.Shell organizes an annual university competition called Shell Eco Marathon. The goal is to buildthe car that consumes the least fuel during a race. KTH participated for the first time in 2006.The engine for this competition, DoubleTwo, has been developed within the school. Theprinciple is a two stroke counter piston HCCI engine with variable compression ratio. HCCIstands for homogenous charge compression ignition.

Analys av nivåproblematik i dränagetank på Ringhals 1

The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.

Effekter av studie- och yrkesinriktad vägledning på gymnasieskolan ? Effekter av vägledning, avseende gymnasieelevers valda program

The purpose of this study was to investigate the effect of educational and vocational guidance, refer-only high school students tend to stay on their first selected program or to change the program. The theories used in the study deals with young people's choices and choosing education and vocational and life role as a student. The method was quantitative, descriptive survey. High school students in grades three, from two high schools, were asked to answer a questionnaire about perceived educational and vocational guidance. Convenience sample consisted of 162 respondents (N = 162), 86 women and 76 men.

Magnesiumintagets betydelse för blodtryck och magnesiumkoncentrationen i stickprov av urin, träck och blodplasma hos häst

The purpose of this trial was to evaluate the possibility to use sampling of faeces, urine and plasma, and measurements of blood pressure as methods of discovering hypomagnesemia in horses, as well as the application handiness of these methods. The most commonly used method of checking the magnesium status of a horse is to analyze samples of serum or plasma. The trial was of a switch-back design, in which the horses were used as their own controls. The animal material was five Swedish warm blooded trotters between six to ten years old, and weighing between 485-620 kg. The trial consisted of three periods that were two months each.

Spillningsinventering för bestämning av älgbetesbelastning på ungskog

In the 1980?s the moose population in Sweden grew explosively due to big changes in the silviculture with clear cuttings instead of single-tree selection. Clear cuttings brought big areas of young forest and therefore a lot of fodder in one place. Since this change, the discussion about how to manage the moose population has grown into a very big problem. Forest owners think that the population needs to be strongly reduced because of all the damage that is done to the young forest when the moose seeks its food, and the economic losses because of that.

Self-efficacy, arbetsprestation och arbetstillfredsställelse på ett callcenter företag i södra Sverige

This essay looks into the concept of self-efficacy and its implications for work performance. The participants in this study work for a call center company situated in the southern part of Sweden. The hypothesis is that a high degree of self-efficacy exerts a positive effect on work performance. Furthermore, the study seeks to identify the factors that give rise to work satisfaction among the participants. The results of the study show that there is a negative correlation between high self-efficacy and work performance.

Implementation av High fantasy i Steampunk-koncept

Syftet med detta arbete är att undersöka om man med utgångspunkt i Steampunk-genren inom datorspel, kan göra en implementation av stereotypa High fantasy-element och hur det kommer att uppfattas av Steampunk-entusiaster. Kommer de överhuvudtaget att märka skillnaden och om så är fallet, hur pass stor inverkan tycker de att implementationen har?För att undersöka detta så skapades två karaktärskoncept, en man och en kvinna. Dessa karaktärer utrustades sedan med fyra uppsättningar karaktäristiska kläder och föremål från Steampunk-genren. Sedan lade jag till två stereotypa detaljer från High fantasyn på varje karaktär.

Testbänk för luftlager

Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.

Hur mycket "mjölk" ska det vara i mjölken, och hur styr vi det?

In most countries, the dairy industry focuses on the volume of milk produced instead of its composition. This results in a high content of water and a lower proportion of fat and protein. A high proportion of water is not desirable when processing the milk into various dairy products like cheese, cream and milk powder. High water content also increases the costs for transport and storage, and also an unnecessary, albeit marginal, strains on the world?s water reservoir.

"Vi har fått jorden till låns av våra barn och barnbarn" : Hur undervisas hållbar utveckling på högstadiet?

The discussion about high culture and popular culture in our society has been going on for decades. In few places is it as loud as within culture journalism and the critics? society, where the question of what is good taste and what is dumb entertainment constantly gets brought to the surface. Film is a particularly vulnerable area, since it is such a universally appealing and rather young medium. In America and England several studies have been performed of the reviewing society and reveiwers? use of high and low art-discourse in their writing.

Utveckling av processparametrar inom en hårdmetallindustri

This report analyzes and examines a hypothesis for finding a method to optimize thelength of the delubrication process time based on a total charge weight. The work hasfocused on the holding time for delubrication and the total charge weight.An important step in the manufacturing chain of cutting tools is when the greenbodies undergo the sintering process. Today, the delubrication step has the sameprocess time independent of the total charge weight. An implementation of a methodto adjust the delubrication process time would give more consistent quality of thecutting tool´s internal characteristics but also reduce the time course of the sinteringprocess. In the present project two methods for this goal were tested, thedevelopment of an algorithm and a weight interval subdivision with associateddelubrication process times.During delubrication a pressure increase is observed due to the decomposition of thePEG in the powder mixture.

Surfplattor som studieverktyg : En artefakt för mediering

Swedish schools have during the last few years started to providing pupils in high school with tablet-computers. By doing interviews I examine how pupils in high school use tablet-computers in different ways and how that affect their studies. From a sociocultural perspective and with the concept of artefacts I analyze how suitable tablet-computers are for studies on this level of education. My results show that the tablet-computers are used as the pupils primary study tool. They are available to all pupils and can be used in most parts of their studies and this creates new opportonities in how to interact with collective knowledge and with other people.

Varför lyckas inte alla? : En studie på Hantverksprogrammet Frisör och Florist om skillnader mellan hög- och lågpresterande elever.

Our purpose with this study was to investigate whether there was any difference between high and low performing students from selected aspects such as choice of studies, achievement, self-image, motivation, confidence and career choices.A training professional in today's schools requires knowledge of how young people think about their lives for us to help students develop both high-and low-performing students. Students have different conditions, but no matter good or bad conditions, each individual pupil must be allowed to develop.The concepts used in the study are of study, self-image, motivation, achievement in the future and career choices. In the background, describes these concepts through literature study. The method we have used was semi-structured interviews. Which means a fixed structure, but with room for follow-up questions.The results of our study indicate that there were clear differences between high-and low-performing students.
