Perianestetisk omvårdnad av häst :
This work is a combination of a literature study and a practical pilotstudy. In the literature study essential physiological reasons of why anaesthesia of horses is so risky are explained. Diffrent methods of induction and recovery are brought up, together with significant aspects of positioning the horse on the operating table and perianaesthetic complications such as myopathy, neuropathy and limb fractures.
The pilotstudy had the purpose of examine the bodytemperature of horses undergoing general anaesthesia and to control the perianaesthetic temperature measurements performed in Swedish horseclinics and veterinary hospitals. Our hypothesis was that the bodytemperature of the horses would decrease but not enough to cause a problem.
The purpose of this work has been to gather more profound knowledges in the subject of perianaesthetic nursing of horses which is an important part of the assignment of a veterinary nurse..
Brännkammare för träpulver : Teoretisk analys och praktisk försök
The thesis describes a completely new biofuel system to generate particle-free heat from combustion of ash-containing biofuel particles at high temperatures.The suggested system gives opportunities to introduce biofuels in new areas.Main components in the suggested system is a heat radiating combustion chamber intended for pulverized wood, combined with regenerators to extract heat from flue gases and simultaneously preheating the combustion air.The thesis contains a description of the suggested system, theoretical considerations, calculations regarding the combustion, and includes results from tests performed.The results from calculations and tests performed concludes that the system is workable and possible to apply..
Effekter av tidiga reflektioner vid musikreproduktion
In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.
Uppfyller BIM förväntningarna som arbetsmetod för broprojekt?
The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.
Observatörer för skattning av verktygspositionen hos en industrirobot : Design, simulering och experimentell verifiering
This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn has led to problems with flexibilities, nonlinearities and friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based on an Extended Kalman Filter and a deterministic variant. They have been evaluated in experiments on an industrial robot with two degrees of freedom. The experimental verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz.
Påverkan av skuggor från vindkraftverk
To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.

Produktutveckling och prestandatest av ett vattenvärmedrivet torkskåp : Jämförelse mellan tre utvecklade versioner av ett vattenvärmedrivet torkskåp
AbstractElectricity consumption is a globally increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high efficiency because they use the residual heat for domestic heating. The CHP plant often use fuels from renewable resources, giving them a lower carbon footprint, but are also depending on the heat demand. If electric powered products such as drying cabinets convert to heat powered products more environmentally friendly electricity will be produced by CHP plants, which can supplant electricity, produced from coal power plants and reduce carbon emissions.
Identifiering av merva?rden i EPC-projekt
In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

Organisationsförändring vid implementering av ett affärssystem : Den upplevda förändringen av arbetsroller och styrning hos de anställda på Lantmännen Cerealia Uppsala
När en organisation väljer att implementera ett affärssystem, leder det till en stor teknologisk förändring, men även en stor organisationsförändring. Det faller sig då naturligt att implementeringen kommer att ge intryck på organisationens övriga verksamhet. Uppsatsen redogör för om och hur de anställda i en organisation, som implementerat ett affärssystem, upplever förändring i sina arbetsroller samt i organisationens styrning. Arbetsroller inkluderar både de anställdas arbetsuppgifter samt deras relationer till kollegor. En fallstudie har gjorts på Lantmännen Cerealia Uppsala, där detta undersökts ur ett lednings- och avdelningsperspektiv.
Vem bestämmer över kvaliteten? : Bibliotekariers privata och professionella syn på kvalitativ skönlitteratur
With an increased empowerment of the users, and a dependence on outside critics, one wonders what kind of role the librarians have in a context where qualitative literature is discussed. The aim of this study is to examine the relationship between librarians private and professional views on qualitative fiction, in order to be able to discuss their role as quality intermediaries in a user oriented context.The method used, is the qualitative, semistructured interview. This author interviewed seven librarians from three different libraries in Sweden. The theoretical emphasis partly relies on the ten words of qualitative value that Inger Elam and Bengt Brülde discusses in their respective texts, partly on David Garvins quality assessment theory, which defines several quality categories divided between an absolute and a relative quality view.Through the comparison between the private and the professional quality view, examined with the two theoretical approaches, the analysis of the interview material shows that there lies a complexity in the librarians professional role. On the one hand, they are dependent of both the users and the critics judgements about the qualitative aspect in the work with purchasing new literature to the library.

The aim of this paper is to investigate the opportunities for associations for PLHA in Tanzania and Uganda to affect in the national level of politics.
Mode som narrativ : En analys av modets roll i The Picture of Dorian Gray
My aim with this study has been to examine how the fashion is a leading component in the novel The Picture of Dorian Gray.I have studied the role fashion plays in the novel and in which way it can be seen as a way of letting the reader know the important role of fashion in 19tcentury England and the morals of Oscar Wilde.To prove my thesis I have used literature that shows how Oscar Wilde uses influences from his own life in his writing of The Picture of Dorian Gray. I have also used Judith Butler's theory of performativity in analyzing the characters in ordet to display their way of staging themselves and their lifestyles and their dependence of that performativity in their interactions. Even though the theory of performativity often is used to hold the importance of the sexes, I have concluded that it has an important role in the novel when Dorian Gray interacts with the character Sibyl Vane who is an actress. My results have shown that fashion in the novel is often a way of letting the reader know important elements of a character in the way that certain fabrics and items are mentioned when Wilde writes about his characters. I have also found that fashion is an important factor when the characters judge each when they speak about the way they dress.
