Evaluation of a method for determinationof glutathionereductase activity inerythrocytes
Glutathione (GSH) is a molecule that consists of three amino acids: glutamic acid, cysteine and glycine. GSH has several important functions: to protect cells from free radicals, reactive oxygen species and oxidative stress. GSH exists in a reduced form, GSH, and in an oxidized dimeric form, glutationdisulfid, GSSG. The enzymes glutathionereductase (GR) catalyses the reduction of GSSG back to GSH. Nicotinamide adenine dinucleotide phosphate (NADPH) is required as a coenzyme in the reaction.
Testeffekten som medel för att förbättra läsförståelse?
Swedish school children exhibit deteriorating knowledge results in terms of reading comprehension. Previous research shows that a method to increase the level of knowledge is the use of evidence-based learning techniques. Test based learning generates what is commonly referred to as a test effect, which proved to strengthen the relationship between learning and memory, as well as being applicable to various test formats. The purpose of this study was to investigate whether test based learning, in terms of learning english words leads to increased performance in a reading comprehension test, more specifically a cloze test. The study was based on a within-group design and was conducted three times over four weeks.
Känsla av sammanhang i förhållande till ålder, egenupplevd sjukdomsbild och hälsotillstånd hos en grupp individer med reumatiska sjukdomar
Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.
Redesign av gallervält för Svea Redskap AB : Examensarbete, produktutveckling
The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.
Elektronisk Handel : Framtagning av två implementeringsmodeller
This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.
Bärförmågetillväxt i pålad friktionsjord
Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and 75 % during the first 90 days after pile installation. This showed that the effect of the phenomenon is difficult to predict. A study involving five projects have been carried out by specifying certain parameters like pile type, method for pile installation and test method for measure the bearing capacity in friction soils located in Sweden.
Användarstyrt förvärv vid tre högskolebibliotek
User-centred acquisitions at three academic librariesA new way of developing collections has been adopted at a number of small academic libraries, user-centred acquisitions. The method implies that the main way of building the collection is by means of receiving suggestions of titles from library users. The main purpose of this thesis is to investigate changes in acquisitions of monographs. At a more detailed level it seeks a deeper understanding of what user-centred acquisitions is and how the method effects the acquisitions process. Changes in stock management and the reason why the libraries have chosen the method is investigated as well.
http://en.wikipedia.org/wiki/life - Den levande boken
Http : // en.wikipedia.org / wiki / Life is a book with a life of its own. It is made to raise questions about the importance of the book, and the paper book in particular. It is a design project in which a new design method is being tested and evaluated. The intention of the project is to determine whether a concept can be found and evolved from a chosen subject or not. The aim of the book project is also to investigate if the form and content of the book could be entwined, making it impossible to separate them from each other..

Optimala reduktionsgränser för kalldragna rör : Optimal reduction limits for cold-drawn tubes
Dragbänken installerades på avdelning kallbearbetade rör på Ovako i Hofors 1990. Sedan dess har kvalitetskraven på de dragna rören ökat. Samtidigt har produktivitetskraven ökat, det vill säga att tillverka rör till rätt kostnad. I produktionsplaneringsprogrammet finns gränser och regler för hur de dragna rören ska tillverkas för att rätt kvalitet och kostnad ska uppnås. Eftersom både de dragna rören och de varmvalsade ingångsrören har ändrats med åren så stämmer inte alltid gränserna och reglerna idag.
Att arbeta med konflikthantering : implementering och undersökning av en form av fokusgruppsamtal i skolan
I have chosen an action research approach for this essay. I want to incorporate a method of conflict management in the work of the personnel at a school and also discuss their thoughts and experience in conflict management. I wanted to incorporate modern knowledge about constructive conflict management for everyday use and I stress that if we can evolve these skills among the personnel in schools then we have a better chance of helping children with deviant behavior which often end up in conflict because of it. This will also help all the other children and personnel to manage conflict situations in a better way. I want to introduce a new way of thinking about conflict management which in many ways is different from how it is today. Briefly the method which I advocate revolves around paying attention to every ones basic needs and says that everyone can win and no one has to loose. he main purpose of this essay has been to find out if focus group conversations is a viable method for improving conflict management in the school system. Several of the participants has in their evaluations written that it was a rewarding and interesting way to work.
A Comparison of Two Immunoturbidimetric Assay Methods for Serum Amyloid A in Cats.
The analysis of acute phase protein serum amyloid A (SAA) has recently been brought into clinical use in veterinary medicine. Some of the difficulties with incorporating the SAA method in clinical practice have been the expensive and rather large equipment required for the method. Due to these difficulties only larger clinics can afford to use the SAA analysis.The company Equinostic has recently developed a smaller instrument that costs one-tenth of a larger instrument. The instrument is named EVA1 and has so far only been used to analyze SAA in horses.The aim of this study was to investigate if the EVA1 instrument could be used to analyze SAA in cats. This study included 24 serum samples from cat, which were first analyzed twice on the EVA1 instrument and then sent to the Strömsholm Referral Animal Hospital in Sweden where they reanalyzed the samples using a validated reference method.
Representationer av döden i ungdomsfilm utifrån analyser av Hungerspelen och Jag saknar dig
Regarding death in youth movies,analysis of Hunger Games and I Miss You Today, death is not as present in our everyday life as it was before when everyone knew how death both looked and smelled. This means that media today has a different role and that media can help their viewers to mourn and become aware of death in a completely different way. In this study, death is analyzed as an representation; how it affects and is experienced in two selected youth films, The Hunger Games, (Gary Ross, 2012) and Jag saknar dig/I Miss You (Anders Grönros, 2011).Previous studies mostly analysis death as a figure, and in accordance with these studies have concentrated on different physical descriptions of death; often about diseases or how death is portrayed in the news. In my opinion, these studies lack the perspective of how death is presented, but also how young people respond to these deceptions of death. This essay highlight different perspectives and show more of how death occurs, how the cinematic look is described and how young people react to what is happening on the screen.
Galactose in dairy products
Milk and milk consumption has been subject of discussion for a long time, and is still a hot topic. Recently, as study was published that observed a correlation between milk intake and increased risk of fractures and mortality. The authors proposed the milk?s content of D-galactose as the possible mechanism, since D-galactose is used indicated ageing in animal models. Therefore, this study aims to develop a method to determine the amount of galactose, glucose and lactose in milk and fermented milk and apply it on to dairy products on the Swedish market.
Optimering av indunstningsprocess
The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.
