Tidsåtgång i system med självgående/självlastande fullfoderblandare :
In this study I have compared two systems of handling TMR, self-propelled/ self loading mixers and conventional towed mixers, what has been investigated is the time for filling, mixing and feeding TMR as well as maintenance and fuel consumption. The background of this study is the structural rationalization within the Swedish milk production that has put focus on efficiency and reducing of costs. Forage and labour are the two biggest costs in milk production today.
The study has been performed by visiting three farms and with a stopwatch measured the times for filling, mixing and feeding TMR. At the time for the visits, the users have been interviewed regarding maintenance and fuel consumption. They have also had an opportunity to give comments of how they experience the mixers.
The result of the study after processing is that the average stock in the study can save 74000 SEK a year by reducing time for filling, mixing and feeding TMR to cows with a self propelled/ self loading mixer .
The conclusion I can make of this study is that it?s not the size of the stock that decides whether it?s interesting to invest in a self propelled/ self loading mixer, but the presumptions on the farms, for instance forage logistics and mechanical equipment..
PRAKTISK BESTÄMNING AV KLÄMKRAFT OCH FRIKTION I SKRUVFÖRBAND
This report reflects an examination work performed for Getrag All Wheel Drive AB during the spring of 2005. Among the companies range of products there exists some concern regarding the amount of clamping force and friction on bolted joints caused by the assembly torque.The aim of this project has been to determine if there is a simple way in which to identify and then practically apply testing methods for clamping force and friction through utilization of existing testing equipment.Three separate methods of clamping force and friction determination have been tested in rear drive unit, RDU, at a 30 Nm assembly torque. A fourth and final method, screw elongation with ultrasound, has been used as reference. The methods are:?Torque-Tension test.?Screw elongation with micrometer.?Joint stiffness test.?Screw elongation with ultra sound for reference.The results from tests can be viewed in table below.MethodTorque-TensionMicrometerCs=318 kN/mm Assembled with torque wrenchMicrometerCs=318 kN/mm Assembled on lineUltra-soundCS=311 kN/mm Ultra- soundCS=318 kN/mm Joint stiffnessTheoreticalClamping force-21,8 kN17,6 kN17,3 kN17,6 kN17,1 kN17,3 kNFriction-0,110,1470,1530,1470,1520,149.
Närståendes delaktighet inom psykiatrisk slutenvård : Ur ett livsvärldsperspektiv
Today adult patients' relatives are seen as a resource in psychiatric care but few researchers have examined the lived experience of relatives' participation in psychiatric care. The aim of this study was to illuminate how mental health staff and relatives of adult patients experienced the relatives' participation in psychiatric care on hospital ward.The study was guided by a phenomenological approach and a lifeworld perspective. Data were collected through in-deep interviews with ten adult patients' relatives and three group-interviews with ten mental health carers from two hospitals in Sweden.The essence of the lived experience of relatives' participation in psychiatric care in hospital ward is described in the constituents: invitation to participate in psychiatric care; meet the staffs' care; to participate in own or others terms; bring the common everyday world with you; feel burden; participation a trip in time and space. The findings of the study show that the relation between the staff and the relatives are important for the relatives' participation in psychiatric care. The relatives' participation can alter from no participation to a meaningsful participation, from suffering to well-being.This study can help medical staff to understand relatives and their participation in a new way..
Sensorfusion av GPS och IMU för en racingtillämpning
AIMS AB is a Swedish company that develops and sells inertial sensor systems. A new product is under research which basically is an aided inertial navigation system where unwanted drift is eliminated. This can be done by integrating a GPS reciever into the system and fuse measurement data from GPS and IMU. Such a product is useful in racing, where engineers always are searching for the optimal performance and the shortest lap times. Today the only feedback the engineers and mechanics get from their work is the driver?s comments and lap times.
Utveckling av styrning till solföljande MaReCo-hybrid i Hammarby Sjöstad
Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.

Aim: The aim of the study was to examine KAMEDO-reports concerning prehospital medical management on disaster sites. Method: Eight KAMEDO-reports was examined with focus on organization and management. Results: Four areas in which all could be influenced by the healthcare personnel in leading position was described: Management and Co-operation, Load and Go - Stay and Play, Priority and Triage.
Undersökning av exponeringsindex för bildplattesystem inför optimeringsarbete
The county hospital of Dalarna has for the last couple of years carried through a process of digitalization. The result is that within the county it exists image plate systems from two different manufacturers. In an attempt to create a tool for dose optimization and dose surveillance the county of Dalarna would like to investigate if the exposure index from Agfa and Fuji is suitable as a dose indicator. An investigation of the exposure index, S, from Fuji has already been done. This thesis has been continuing the investigation by evaluating the stability of the exposure index, lgM, from Agfa.
Intranät En kommunikationskanal för alla?
Intranet is today a common technical groupware to communicate in many organisations. People can interact through the Intranet and communicate within the organization and get relevant information according to their workplace. It can be difficult to get everybody to use the Intranet as an information- and communication tool. This causes problems when people want to reach out with information. With these thoughts we entered our work at Luftfartsverket at Arlanda airport.
"Hälsa" i ämnet idrott och hälsa : En studie om elevers tankar, uppfattningar och erfarenheter
The purpose of this study has been to investigate how the temperance movement IOGT in Karlstadcampaigned for people to vote for a referendum on alcohol in 1922 and how it has been tackled bythe local press. To answer the purpose a qualitative text interpretation has been used from IOGT'smeetings protocols and the local press used are the two largest newspapers in Karlstad during thisperiod of time, Karlstads-Tidningen and Nya Wermlands-Tidningen. The type of examinationperformed is called interpretive case study where it has been used a theoretical basis. Thetheoretical point is Habermas Bourgeois publicity also been used by Lars Båtefalk in his thesisStaten, samhället och superiet. Can the temperance movement be said to take part of the publicsphere?The results show that IOGT during this period have grown large enough to be a part of the publicwhich Båtefalk mean was not the case around 1900.
In Der Fuehrer?s Face : Hur populärkultur kan nyttjas för politisk propaganda
This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

Furthermore this thesis has a descriptive- and an explorative purpose.
Läkarstudenterna och det symboliska kapitalet. : Kulturella och andra symboliska tillgångar hos läkarstudenter på Karolinska institutet.
I uppsatsen undersöks kulturellt och annat symbolisk kapital hos läkarstudenter vid Karolinska Institutet. Det teoretiska ramverket utgörs av Pierre Bourdieu. I studien jämförs läkarstudenternas investeringar i utbildning, mediavanor och andra kulturella aktiviter med fyra andra elitinriktade utbildningsprogram i Stockholmsområdet. Studien har en kvantitativ del med data insamlat genom en postal enkät till högskolestudenter och en kvalitativ del med personliga intervjuer med läkarstudenter på termin fyra på Karolinska Institutet. Studien visar att läkarstudenterna har mycket gemensamt med studenter vid de andra utbildningarna men att det särkskiljer sig i vissa avseenden.
Orsak till sjuksköterskans stress och hur den påverkar omvårdnadsarbetet : En litteraturöversikt
Nurses in health care have a responsible and sometimes stressful job. Nowadays there?s a high pace in health care where many decisions have to be made during time pressure, a lot of information has to be transferred between health care units and sometimes complicated equipment are used. Cases of mistakes are reported more than ever to the national committee responsible for health care. Many of the mistakes, where the nurses are involved are due to the nurses? stress.The aim of this study was to gather information to describe causes of stress in nursing care and the nurses? experience of stress influence on health care.The method that was chosen for this study was a literature review where scientific, critically reviewed articles were analyzed. The analysis resulted in two main themes.
Ett tv-formats utformning mot publicering på webben: Skall television utvecklas, anpassas och förändras utifrån sin publik?
Watching television (TV) has been given a new meaning, you don?t have to book a specific time, a specific date if you don?t want to miss the program you were planning to see. In Sweden now days we can watch TV in lot of different ways, whenever we choose to do so. In this thesis I attempt to explain and document the process of shaping a tvformat, the development and adaptation to a time when the TV medium is in a change. Plus a look at how the television audiences relate to their use of it.
