ABB I-R Waterjet Systems combines the robotics and motion expertise of ABB Flexible Automation with high-pressure intensifier/pumping technology from Ingersoll-Rand to provide and continue to develop innovative waterjet cutting systems for global markets. The purpose of this assignment is to develop a process water purifier. The purifier should be applicable as an option to ABB I-R?s production cell Cutting-Box. At first hand the process water should be purified well enough to let out in the municipal sewage system, but the ultimate solution is purifying the process water to the range that recycling is possible. When investigating the different principle of purifying water, a research of different products and their manufactories was done. These different products were compared and the principle of filtration was the most applicable, as most of the products were designed for far larger applications. As the process water contains quite large amount of particles, it is necessary to perform the filtration in different steps. The process water purifier is therefore composed of a module of coarse filtration and one of micro filtration. In the module of coarse filtration the mainly amount of fibres and particles are eliminated. They are kept back in the container unit with the larger fragments and dumped with these when the container is emptied. In the module of micro filtration the filtration is performed in two steps. In the first step particles larger than 50?m are eliminated, in the second step the micro filter is setting the range of purifying, in this case 10?m.

Disturbances, such as fire and wind, are important for saproxylic beetles (= beetles depending on decaying wood) to gain substrate in boreal forests. Clear-cutting is an example of a man-made disturbance. Measures such as prescribed burning have been made to resemble natural disturbances. The aim of this study was to see which clear-cut characteristics are important for the occurrence of the saproxylic beetle Upis ceramboides. This is a species favored by open habitats and is said to respond positively to forest fires. The distribution area in Sweden for this species has decreased during the last two centuries and I wanted to see if there were differences between clear-cuts in Hälsingland, where it is very rare and decreasing, and Norrbotten where this study was conducted.

To make wave power more competitive on the market Uppsala University leads projects that examine how to accomplish better efficiency in the production. One of these projects is described in this report and examines whether it is possible to make the production of dovetails more efficient by using an industry robot of type ABB IRB6000 S3 M91. This project is using an already presented working method, from a previous project, which involves that the robot picks up the dovetail and moves against fixed cutting machines where the dovetail will be drilled, threaded and milled. Drilling and threading are the sub operations that will be examined in this project where experiments are made with the presented working method and with equipment from Uppsala University.Experiments show whether it is possible to drill the holes in the dovetail within specifications by using the specific robot and the presented working method. The threading operation is examined theoretically if it is possible to accomplish by using the same working method.

Today?s forest managers implement a large number of methods to increase the amount of dead wood in Swedish forests. They use everything from high cutting of trees to girdling trees and burning forests. However, implementation of these measures without proper knowledge of their consequences is a common problem. This study has been performed to increase knowledge about two of these measures, girdling and high cutting, and how these actions affect the number of wood-living insects living on dead trees.

This essay is a product of the author?s interest in silent films from Soviet, especially, documentary films. Before the 1920?s documentary filmmaking had mostly been limited to newsreels and short scenes. Only occasional feature-length documentaries had been made.

The purpose is to illustrate the phenomenon of self-harm from a social psychological and sociological perspective. The purpose is furthermore to examine the role social relationships play in the individuals´ self- imagine and what role does identification play for anyone who harm themselves? We want to examine in what way social relationships are important and how they function for individuals who harm themselves, both once they have started to harm themselves, and if the relationships in any part caused the cutting to begin with.Questions:How do individuals shape their identity based on self- harm? Which self-image do individuals have who self-harm? Is there anything in the person's previous social relationships that have caused them to begin to hurt themselves?Method:In this paper we have analyzed five autobiographies. We have used open coding from grounded theory as analytical method and subject positions based on discourse analysis.Theory:We have used the Cooley concepts looking glass self, Foucault's theory of power, Giddens' concept of ontological security and existential anxiety.Results and Analysis:We found six different categories that we thought were central. These were negative self-image, guilt, lack of family support, negative experiences of others' views, the protective identity as self- harmer and insecure social relationships in school.Conclusion:The self-harming is a very complex behavior.

I detta examensarbete har en studie genomförts av hur väl 3D-skrivning kan tillämpas i Volvo Cars i Skövdes produktion. En litteraturstudie har genomförts för att åskådliggöra de olika 3D-skrivningsteknikerna och deras användningsområde. För att på ett överskådligt sätt jämföra de olika teknikernas duglighet har en bedömningsskala utvecklad av Nasa använts. Denna skala benämns som Technology Readiness Level (TRL). Den teknik som bedöms som mest lämplig med avseende på fullskalig produktion samt prototyptillverkning är Selective laser melting (SLM).För att åskådliggöra fördelar med 3D-skrivare har en förenklad 3D-modell av Volvos cylinderblock I5D modellerats.

SCA Skog has taken the initiative to this Master?s thesis. Today SCA Skog has a great need to update their informtion on young forest stands across large areas. Traditional field inventory methods for updating stand databases are expensive and time consuming. However, the inventory could be made more efficient if stand boundaries and stand characteristics are derived from aerial photographs.

Costs of maintenance on combines are a subject of interest thus it constitute a large investment and cost for the individual farmer. Therefore it is important to have up to date knowledge and the right facts to be able to do reliable calculations on one of the largest investments for a farmer. The aim of this study was to compare costs of maintenance on combine/threshingmachine with the computer program for advising environmental issues in agriculture, STANK. Interviews took place and data were collected by handing out questionnaires to 20 farmers. A similar study conducted by Neuman (2003) investigated costs of maintenance and compared these with STANK. The results of this study have also been compared and examined related to data from SLA - Skogs och Lantarbetsgivarförbundet. The result shows that 18 out of 20 combines were given a higher cost of maintenance when using STANK compared to the numbers in this study.

This paper analyses the character judge Holden in Cormac McCarthys novel Blood Meridian through an ethical perspective. The author uses several methods to analyze the character ethically, such as the western-genre, McCarthys authorship, evil as an ethical term and Friedrich Nietzsche's theory the Übermensch. The author then uses a selective group of scenes and chapters from the novel to highlighting the distinctive ethical characteristic of judge Holden. The author finds judge Holden to be the very principle of violence and blood shedding, defending and distributing these principles in his words and his actions throughout the novel. Triumphantly proclaiming his victory, judge Holden embodies the principle that whoever has the power to perform any action has then the moral right to do so.

Syftet med föreliggande studie var att undersöka effekten av en dos mindfulness session på 45 minuter och dess relation till: (1) Upprätthållandet av uppmärksamhetsförmågan, (2) exekutiv uppmärksamhetsförmåga samt (3) perceptuell förmåga. En experimentell studie genomfördes på idrottare (n=48) som uppfyllde särskilda krav för att få ingå i studien. Resultatet visade inga signifikanta skillnader gällande samtliga tre variabler mellan experimentgrupp och kontrollgrupp. Avslutningsvis diskuteras studiens resultat och implikationer i förhållande till tidigare forskning, med stöd av teoretiska referensramar..

When cylinders for motor saws are manufactured there are high demands on the cylinders strength and wearing qualities. Aluminum is a material with low density and is used by Husqvarna AB for their motor saw cylinders. The aluminum is strengthening with nickel that is attached to the cylinders through electrolysis. When aluminum is in contact with oxygen a film of oxide is formed. To eliminate the oxide and to prevent formation of new oxide zinc is used.

Den här studien genomfördes i Helsingborgs kommun som ett examensarbete inom livsmedelstillsynsprogrammet på Lantbruksuniversitet (SLU) i Uppsala. Idén med uppsatsen uppkom efter att författaren deltagit i ett möte på miljökontoret i Helsingborg. En kontroll som gjorts bland livsmedelsbutiker i kommunen visade att 60 % av livsmedelsbutikerna fick underkänt vid inspektioner. De områden som fick flest anmärkningar var rengöring och underhåll av lokaler och utrustning, internrevision och temperaturer i kylar och frysar. Över hälften av butikerna fick underkänt vid kontrollen vilket visar på att det uppenbarligen finns brister i egenkontrollen.

The aim of this study was to examine self-harming women?s own experiences. To try and raise understanding and awareness about how they themselves create their identity and meaning round the self-harming behaviour. Our three questions were; how do the young women conceive society?s reactions on their self-harming behaviour? Do the young women express an imposed or self-elected alienation? If so, in what way? In what way do the young self-harming women construe their own identity in relation to the self-harming behaviour?We have used a narrative approach when we have examined the blogs as life stories in the sense that all our lives and everything in them is a story by definition.

This report is an assessment of the feasibility of using aerial photographs to estimate number of stems per hectare in young forest stands, used together with upper height to determine the need for pre-commercial thinning or ordinary thinning cutting. Aerial photo-interpretation was conducted in 2007 on assignment of Stora Enso Skog AB. A mean height function based on stand age produced with data from Bergvik Skog AB?s 2006 forest inventory assessment was used as a proxy for upper height and used together with photo-interpreted number of stems per hectare to determine the need for thinning cutting according to Bergvik Skog AB?s definitions. The test area is located north of Falun on Bergvik Skog AB?s land.Flight altitude was approximately 900 m above ground and the aerial photos were taken by L&L Flygbildteknik AB.
