The game QuantoJump is developed in the programming language Java to be an educational game in quantum physics. By illustrating quantum mechanical laws of Electron transitions with shapes and colours, QuantoJump hopes to spark interest and create a more intuitive understanding of quantum physics. The result is a game where the player plays as an Electron in the outermost shell of an atom, with the goal of getting to the innermost shell. This while not making forbidden jumps by following the laws of Electron transitions dictated by quantum physics. The programming of the game was done in the integrated develpoment environment Eclipse.

ABSTRACT Tobacco Rattle Virus (TRV) is a soilborne plant virus. It is an important pathogen in potatoes where it causes spraing disease. This disease can lead to significant economical loss for the farmer, so it is imperative to get the proper diagnose before planting. TRV is spread naturally by free-living nematodes (Trichodorus and Paratrichodorus). Transference of TRV to a plant occurs when the virus-carrying nematodes feed on plant roots. The relationship between virus, nematodes and plants is complicated, and has to these days not been fully characterized. The diagnostic methods available today do not work sufficiently.

Bull terrier hereditary nephritis is caused by a mutation that leads to an inadequate synthesis of collagen type IV, which is an important component in the basement membranes. The inheritance of the mutation is autosomal dominant in bull terriers and progression to renal failure takes variable time, from several months to ten years. Proteinuria is the first clinical sign of the disease and the diagnosis is confirmed by transmission Electron microscopy of renal tissue where typical ultrastructural changes in the glomerular basement membrane (GBM), thickening and multilaminar splitting are found. This study was performed in order to find out the occurrence of hereditary nephritis in bull terriers in Sweden through examination of urine samples and renal tissue and comparisons with how the disease is described in the literature. Urine samples from 76 Swedish bull terriers were collected and examined for proteinuria.

Uppsala University is involved in a large international collaborationto build the Laser heater system for the European Xray Free-Electronlaser in Hamburg, Germany. In this thesis I describe a laser incouplingdevice into the vacuum chamber of this laser heater all the way fromthe specifications to a completed design.The laser heater is a very important part of the XFEL and thepart described here is a part of the vacuum system needed to couplean external laser into the Electron vacuum system and align it withthe Electron bunches in order to heat them. The task was started by studying the literature about the basic theory andthe design of vacuum systems. After this study and collection of ideaswith colleagues I started to prepare different concepts to solve thetask. The ideas can be put into two categories, in one case the couplingmirror is located inside the vacuum chamber and in the second caseoutside.

A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high Electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good Electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.

In a multi-year project at Swerea Swecast AB studies on influence of dissolved gas on inclusions have been made. The knowledge about these parameters could be used to increase the quality of the final steel casting. The purpose of this thesis was to closer examine the impact of the oxygen level on inclusions.The questions asked were:? What was the amount of inclusions at different levels of oxygen?? What was the size of these inclusions at different levels of oxygen?? What does the inclusions consist of at different levels of oxygen?This was studied by measuring and sampling, sample preparation and microscopic analysis using an optical microscope and a scanning Electron microscope (SEM). Measurements and sampling was performed at Smålands Stålgjuteri AB in Eksjö and at Swerea Swecast AB in Jönköping.

Rapporten är en reflekterande text som behandlar arbetsprocessen och omkringliggande mål för ett examensarbete inom medier som bedrivits mot Högskolan Skövde. Syftet med examensarbetet har varit att finna grepp som maskerar spels linjaritet, det vill säga vilka knep som används i dataspelsindustrin (medvetet eller omedvetet) för att få ett spel med linjär level-design till att framstå som mindre linjär.Min analysmetod är hämtad från Espen Aarseths, Forskning på spel: Metodologiska ansatser till spelanalys (2007), där en av de totalt tre analysmetoder är vald; nämligen att själv spela igenom analysobjektet. De två återstående analysmetoderna presenteras kort under metodavsnittet. Därefter jämförs greppens betydelse i en rad spel för att därefter slutligen tillämpas i en egenskapad modul. Jämförelser görs med The Legend of Zelda ? a Link to the Past (Nintendo, 1991), Grand Theft Auto ? Vice City (Rockstar North, 2002) och World of Warcraft (Blizzard, 2001).

The Blötberget deposit is situated in the north-western part of Bergslagen. The mineralization is an apatite-iron oxide ore of Kiruna type. In Bergslagen the apatite-iron oxide ores occur along a zone from Grängesberg through Blötberget to Idkerberget in the northeast and they represent the largest and the most important iron oxide deposit in Sweden, south of Norrbotten.Different REE hosting phosphate phases has been studied by optical microscopy and analyzed by EDS attached to an Electron microscope.The key minerals other than iron oxides are apatite, monazite and xenotime. The relative concentration of the REE-bearing phases differs from the other apatite-iron oxide mineralizations in the area, for example Grängesberg, by a higher concentration of xenotime and lower contents of allanite..

Individual cellulose ?bers were studied to identify the transport and absorbtion phenomena as well as the in?uence of drying. A Chalmers University of Technologydeveloped method within ESEM (Enviromental Scanning Electron Microscope) has been used in this study. The results from the laborations gave the following conclu-sions: The transport of water occurs in ?bers in the ?ber wall surface and the lumen.

The work has been carried out in cooperation with the company Zenit Design in Malmö. The project's goal was to restore, improve and produce an ozone generator. During the project, the authors sought relevant literature in databases, been in contact with US suppliers of fuel cell membranes, Asian suppliers for the processing of Teflon and Titanium parts in mechanical engineering and Swedish suppliers of various standard components. The authors had access to a temporary lab at Zenit and Electron microscope at Halmstad University where material tests were performed. The authors have also had access to measurement equipment to measure amounts of ozone.During the work, the authors have mapped how an existing ozone generator works and then have their own development.

The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.

This paper briefly summarizes Bergslagen as a bedrock province in order to give background to the genesis and presence of REE-bearing minerals (short for Rare Earth Elements) in the region. These mineralizations mainly occur along the REE-line, a line aproximately a hundred kilometers in length between Norberg in the north and Nora in the south with a width of a few kilometers. Situated in the southwest of Bergslagen it is currently one of only a few places in Sweden where REE-bearing iron oxide mineralizations are potentially economically viable for mining. Ore microscopy has been conducted in order to characterize an ore sample from Myrbacksfältet, one of few sulphide rich iron oxide mineralizations within the REE-line. Additionally, an Electron microscope analysis of a sample from Stålklockan, a suspected REE-bearing mineralization also within the REE-line was confirmed by EDS (short for Energy Dispersive Spectrum) analysis.

Nanotechnology, one of the most interesting sciences today will no doubt have an enourmous impact on tomorrow's society and industry. One of the most interesting nanomaterial that has been discovered is the semiconductor quantum dot (QD). This material shows interesting novel properties such as a size-dependent band gap, which is an effect caused by the quantum confinement effect in all three dimensions. Due to this phenomenon the absorption spectrum can be tuned to the desired value by adjusting the size of the QD.This thesis aims to investigate how the solvent ratio of H2O/Ethanol affects the optical and structural properties of copper sulfide QDs manufactured in a chemical synthesis way using modern microwave heating. The process of manufacturing QDs using chemical synthesis often involve a capping-agent to prevent the QDs from agglomerate into bigger structures.
