Barns upplevelse av astma : en litteraturstudie
Asthma is one of the most common diseases among children. The aim of this study was, through a literature review, describing children's experience of living with asthma and show how negative experiences can be turned into positive ones, by the nurse's work. Results showed that many of the children with asthma experienced respiratory- and chestproblems, tiredness, panic, fear, anger, frustration, discomfort, irritation and anxiety. Children felt most restricted in physical activity's. Education used to enhance children's experiences included relaxation, imaginary exercises and confidence training.
"Say yes to yes" : en diskursanalytisk studie om medborgarnas roll i EU
The starting point of this thesis is the debate surrounding the two referenda?s in France and the Netherlands in May and June 2005, regarding the proposal of a European constitution. The aim of this study is to analyse how democratic legitimacy and the role of the citizens portrays within the democratic discourse of the European Union. The empirical material is based upon both speeches from the European Commission and news articles from the French newspaper Libération and the Swedish newspaper Dagens Nyheter. Discourse analysis is used as a theoretical frame of reference combined with models of democracy.
Underhåll av underhållsarbete
The traditional view of maintenance is machine-based, where acute maintenance tasks are highly valued. Preventive maintenance is viewed as secondary and less desirable to work with. The more modern view is to regard maintenance as a process. The machine-driven tasks are still necessary but are viewed as a part of the big picture.The purpose of this study is to examine how to high light general difficulties concerning maintenance management to aid organizations to reflecting upon their own situation. The study is based upon a pilot study initiated by ProcessIT concerning relevant key figures in maintenance.
Utveckling av barnvagn
After contacting the company Elite Group Sverige AB, who sells strollers under the brand Crescent Baby, it was determined that the project group were to develop a three wheeled stroller which was going to be Crescents first own developed stroller. Only the frame of the stroller was considered within the demarcation of this project however care was taken to the placement of the carry-cot and the wheels etc. Crescent Baby wished for the frame would be smaller than the competitor Urban Jungle, that the frame would have at least three unique selling points and that the number of unique parts was to be minimized. The work began with information seeking regarding strollers, competitors, independent tests, European standards and consumer interviews. After that a number of concepts were developed and past to Crescent.
Dagdrömmar
Dagdrömmar är en tapetkollektion bestående av tre fondtapeter som kombinerar det moderna, massproducerade digitaltrycket med traditionell, unik broderiteknik. Genom att tillföra handbroderi och dess struktur och textila känsla till ett digitaltryckt tapetmaterial skapas en kollektion som befinner sig i gränslandet mellan design och konst, lyx och budget samt dröm och verklighet.Daydreams is a wallpaper collection consisting of three images that combines the modern, mass-produced digital printing techniques with traditional, unique needlework. By applying embroidery ? with its structure and fabric texture ? to a digitally printed wallpaper material, a collection is created that lingers on the borders between art and design, luxury and modesty as well as dream and reality..
Identitet, identifikation och kulturella skillnader i animerad film
This essay examines an excerpt of the wide range of animated films that our children has access to in Sweden today.It takes up questions about what kind of messages the films are delivering, if there are certain patterns that are being followed, differences between the films relating to the cultures where they?re from, but above all, what the hero is about and what kind of shape he or she assumes. The film analyses that are being made are anchored in two theoretical investigations; one about how children are influenced by-, and how they use, the stories that are being told in films to develop their own identity. The other one treats classical and traditional patterns and genres in stories..
Interaktion med surfplatta och traditionella leksaker inom förskolan : En studie av likheter och skillnader ur ett socialt- och lärandeperspektiv
The main purpose of this study is to examine differences and similarities concerning teamwork and interactive skills among preschool children while they interact with an Ipad respective a number of selected traditional artifacts. The traditional artifacts chosen for this study are small Lego blocks, JovoToys (click and construct system) and large puzzles. The study takes its starting point on the basis of both a social- and a learning perspective when different groups of preschool children in the ages from three to five years interact in fellowship groups with respective artifact. Primarily the main focus is to examine differences and similarities that appear from without the social perspective.The overall objective is to identify what eventual differences and similarities can be found purposely on both what is happening in the social interaction between the preschool children themselves but also what is taking place in the interaction between the children and each artifact. This study will also via theoretical frameworks create an understanding why eventual differences and similarities exist.The results are based on both a literature review and a field study.
Parameterstudie av inneslutningsbildning och utvärdering av processföring för tillverkning av plastformsstål
This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.
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.
Utveckling av högspänningskontakt
This report describes the development of a high-voltage connector at the request of Scandinova Systems AB in Uppsala. The development process is described from the making of a customer demand specification, to the making of drawings for the manufacturing of prototypes. Scandinova develops high-voltage modulators, hence the need for connectors that can handle very large power pulses. Their current connector has several weaknesses that may cause the connector to melt or catch fire. The development began with a number of studies that included the modulator structure and the current connector structure and functions.
Kalkylarbete för byggnadsprojekt med Vico Office : För- och nackdelar med 5D BIM
AbstractBuilding Information Model/Modeling/Management (BIM) is a tool that allows for efficient working methods. BIM saves time and money while providing the potential for visualization. This method of working is based on a 3D-model, and then a fourth and fifth dimension are connected. 5D modeling means that a spreadsheet creates cost estimates based on the 3D model. This provides opportunities to carry out calculations in the early stages of the projects. Calculations are currently performed manually and do not contribute to the development that the construction industry requires.

ISO 22400 är en uppsättning standardiserade nyckeltal med ändamålet att appliceras på automatiserad produktion. Studiens syfte är hitta vilka av nyckeltalen från ISO 22400 som är lämpliga att använda vid mätningen av en helt automatiserad produktionskedja som tillverkar motorblock.
Läsförståelse i svenska och svenska som andraspråk : En jämförande studie av elevers resultat på läsförståelseprovet i åk 9
The purpose of this study was to find out how gender roles are described in two popular children?s detective stories, one of them written in 2002 and the other in 1946, to be able to compare the two. In order to do this, I used a qualitative research method in which I read and analyzed the text and illustrations of the books out of a gender perspective.I used gender theories describing how stereotypical gender roles are displayed, and these theories were later associated with the books I studied. I also used previous research concerning gender roles in other children's books in order to compare those results with my own.After having read, analyzed and compared the two books, I found vast resemblances between them, but also certain differences. However, it is obvious that the gender roles in both books for the most part are traditional.
