Modellering av reserv- och nödkraftsystem i JAS 39 Gripen

Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.

Investigation of Syndecan-1 Ectodomain Isolated from Chinese Hamster Ovary (CHO) Cell Culture Medium

Syndecan-1 is a cell surface proteoglycan which participates in cell adhesion, differentiation, motility, morphogenesis and intracellular signaling. The two glycosaminoglycans heparan sulfate and chondroitin sulfate are covalently attached to the ectodomain of syndecan-1 via a tetra saccharide linkage sequence. However, the ectodomain can be modified having only one or neither of the glycosaminglycans attached. The glycosaminoglycans are capable of binding ligands such as fibroblast growth factors (FGFs) and support activation of receptors. The ectodomain is proteolytically cleaved from the cell surface by metalloproteinases in a process known as shedding.

Evaluation of a standardized platelet concentration in samples from platelet concentrates measured over time with impedance aggregometry

Platelet transfusions can be necessary during treatment of patients with thrombocytopenia or impaired platelet function. Platelet function in platelet concentrates (PC) deteriorate with storage time. Studying swirling is often used to control the quality of PC?s before transfusion but the method has some disadvantages. Therefore other methods can be useful, for example impedance aggregometry (IA, Multiplate® Analyzer) to measure platelet function.     In this study the change in platelet function over time was examined in buffy coat and apheresis platelets with IA where aggregation had been induced with adenosine diphosphate (ADP) and collagen.

Undervisa engelska på engelska : Ett sätt att göra målspråket till arbetsspråk

High school students of today frequently come into contact with the English language throughradio and television. Many students even manage to read instruction manuals and understandhow technical devices work, such as, for example, computer games. However, most teachersunderestimate their students? ability and persist in using Swedish to explain how the Englishlanguage works. I have analysed how high school students manage when they take an Englishgrammar test in English.

Säkrare träning med rätt redskap.Utveckling av avlastande redskap vid knäböj iSmithmaskin.

The purpose of this thesis was to examine if there where fallacies in the design solutions for the business system IFS Applications from a user perspective, and if so, correct these from a cognitive science approach.Data collection consisted of three main portions. These where; workshop, individual interviews and observations. The collected data was analyzed and resulted in identification of two main areas in the application that where found lacking.The result of the study showed that the usability for processing large amounts of data and the lack of customization where the main flaws in the application. Two low fidelity prototypes where created with the purpose of rectifying the underlying flawed design solutions that where identified from the collected data..

Effects of milking system on plasmin and plasminogen activity in bovine bulk milk

Protein is an important component in various milk products and has a crucial role in the final quality. Excluding non-protein nitrogen, bovine milk contains about 3.3% protein whereas about 80% of this fraction consists of casein. There are four major members in the casein family: ?s1-casein, ?s2- casein, ?-casein and ?-casein. Proteolytic enzymes are the cause of degradation of the economically important milk proteins.

Hur ska skogsfastigheter värderas?

This thesis aimed to describe how the ideological dividing line concerning the welfare state has changed between the two largest governmental parties in Sweden, the Social Democrats and the Moderaterna, during 1990 to 2010. The scientist Mark Blyth points out that ideas are important instruments for structural and institutional change by identifying ideas as weapons, blueprints and cognitive locks, which were being used in the theoretical framework. The empirical data was made by a qualitative analysis of the parliamentary speeches and debates from both parties held every year. The results shows that the budgetary law passed in 1997 became a new institutional blueprint, which changed the political conditions for the Social Democrats. Furthermore, the results point to a change in the Moderaterna?s rhetoric concerning the welfare state to a more pragmatic view. .

Retorik som verktyg vid talängslan : En presentation av Södertörns Högskolas och Uppsala Universitets arbete med talängsliga

The purpose of this essay is to perform a comparative study of first a pedagogical/rhetorical and then a therapeutic method, to help students overcome their speech anxiety. My choice stayed at focusing on the academic world and the benefits offered to mainly students. I have chosen two institutions with long experience of work with speech anxiety: Instutionen of Swedish, rhetoric and journalism at Södertörns Högskola and Student Health at Uppsala University. I want to find the advantages and disadvantages of the two universities and in no way define what is more favorable..

Naturupplevelse och psykisk hälsa : Hur påverkar naturupplevelser människor med stress- och utmattningssymtom

Stress-related diseases in Sweden have doubled since 1997. Even longterm sickness related tostress has increased over the last decade. In future there is a need of alternative methods todecrease the amount of people being affected to gain a better population health. Natureassisted therapy (NAT) was shown to be a successful method as part of the therapy of stressand burnout likewise was nature an important factor to prevent people from mentaldisorders. The aim of this study was to analyse the latest research concearning nature and itshealth effects with focus on stress and burnout patients in order to plan health promotingactivities outdoors for these patients.

Narrativet i skolvärlden : Berättandet i läromedel för historieämnet och dess didaktiska innebörd

This article evaluates the narrative and it´s didactic role in historiographic textbooks for schools. The primary study is a comparing qualitative analysis of the narrative in the different textbooks. The result leads to a pedagogical discussion based on Kieran Egans theories about cognitive tools, and how they shape our comprehension. The theoretical background defining and discussing narrative as a concept is partly based on a semiotic view, part linguistic. The main conclusion of the work is how the narrative seems to be a product of discourse in the ways the textbooks differ at the most from each other; Broken down, how the role of the writer and the reader and their conception of the world take part I a significant comprehension of the stories told in history textbooks..

Beteenden hos geparder i två stora svenska djurparker

Cheetahs in the wild are declining due to hunting, lack of prey, exploitation of habitats and loss of cubs to predators. Those are the main reasons to why cheetahs are kept in captivity today for conservation. Many cheetahs kept in captivity are seen pacing ? a behaviour that arise when the animal is prohibited from performing natural behaviours. It is believed to being attributed to a lack of stimulation in the environment where they are being held.

Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

First the study aim and research questions were formulated. A research protocol was then formulated with inclusion and exclusion criteria and search terms.

Flickor på gymmnasiets byggprogram : en studie om flickors könsbrytande gymnasieval och deras självkänsla

Denna undersökning avser att belysa flickor som gjort könsbrytande val till gymnasiet. Antalet flickor som gör könsbrytande gymnasieval har ökat något de senaste åren. Enligt vägledningsteorin Social Cognitive Career Theory, SCCT, gör individer ?karriärval? utifrån sin subjektiva prestationsförmåga, den s.k.?self-efficacy?. Beroende av hur individen uppfattar sin egen förmåga och värderar sig själv, vidgas eller minskas handlingsutrymmet.

Ungdomars attityder till tobak

Denna undersöker hur ungdomars attityder till tobak påverkas av olika typer av exponering. Det finns idag specifika begränsningar och restriktioner för hur marknadsföring av tobak får se ut i Sverige men trots det exponeras vi dagligen på sociala medier, i affärer och liknande, ofta utan vidare medvetenhet. Vi ville genomföra en undersökning över hur ungdomars attityder till tobak skapas och påverkas av sociala, interna och externa påtryckningar. Genom våra två fokusgrupper har vi lyckats samla önskat material och där av kunnat klarlägga flera svar till hur olika typer av exponering påverkar ungdomars attityder till tobak..
