Plasmodiophora brassicae ? host and environment interactions
In this thesis, three separate experiments have been performed on different aspects of the interaction between the causal agent of clubroot, Plasmodiophora brassicae, and its hosts.
In the first experiment the pathotype of the P. brassicae single spore isolate, which is currently used to construct a reference genome, has been classified using the ECD bioassay. The disease severity of infected plants was scored according to two different scales and the pathotype was determined according to three previously published guidelines. The results were compared to previous published studies describing the e3 isolate.
The life cycle of P. brassicae is not well understood.
En utvärdering av Audiolet för portandet avett röst-drivet program till webben
We where asked to write a webapplication, with similar functionalityas an existing desktop application. The application can todayrecord sounds from a person, mix it together at the optimal place withanother, similar sound and play back the result.The application used mathematical calculation that the developerswhere not familiar with, therefore it was decided to focus on the partsthat involved recording and playing sound, to pave the way for anyfuture implementation.The follwing prototypes where implemneted:1. Read a sound clip from a file.2. Splicing of two sound clips at different points in the clips.3. Generate the sound of a guitar.The result of this evaluation is that web browsers today are notready for this type of application, but that there is potetial as soonas W3C have standardised the use of a microphone as a source to theexisting DSP functions..
Matematikspelet
Matematikämnet och elevers bristande kunskaper i ämnet, har starkt uppmärksammats senaste åren. Vi har konstruerat ett matematikspel i syfte att införa ett arbetssätt i undervisningen, som bygger på pedagogiska faktorer såsom kommunikation, reflektion, social aktivitet och motivation. Målgruppen har främst varit förstaårselever vid gymnasiet. I denna undersökning har såväl elever som lärare och andra pedagoger deltagit i syfte att värdera spelets funktioner som en del av undervisningen. Det centrala har varit hur och om spelet kan stimulera elevers motivation och kommunikation i positiv riktning för att på så sätt skapa förutsättningar för ett bättre lärande.
Räkna - Läsa - Minnas : Vilka samband finns det?
Syftet med studien är att undersöka samband som visas tydligt hos elever i både matematiksvårigheter samt fonologiska svårigheter. Studien har genomförts på elever i årskurs 7 som uppvisat matematiska såväl som fonologiska svårigheter. Resultatet baseras på en filmad observation där eleverna fått lösa ett urval uppgifter konstruerade utifrån svårigheter gällande grundläggande taluppfattning och aritmetik. Elever med fonologiska svårigheter såväl som bristande arbetsminne visar sig ha svårigheter när det gäller att automatisera tabellkunskap såväl som utföra beräkningar gällande de fyra räknesätten..
Grafritande räknare ? hur påverkar de undervisningen i matematik?
The purpose of the study is to examine how teachers and students believe that graphing calculators affect the teaching of high school mathematics courses. By becoming aware of this, teachers and teacher students have the opportunity to reflect on the use of graphing calculators in their teaching. The empirical base consists of interviews with teachers and a survey among students at two high schools in southern Sweden. The results show that teachers especially consider the graphing calculator as a tool, much like paper and pencil. They use it if and when it is deemed able to contribute in a significant way in their teaching, either to save time and/or to help deepen the understanding of various mathematical concepts and methods.
Självlärd eller skolad? : Hur skiljer sig synen på lärande och muciserande bland skolade och icke skolade musiker inom improviserad musik?
In this essay, I will treat the view of learning and musicianship among educated and uneducated musicians in improvised music. The survey is based on six different interviews with musicians in improvised music. In my inquiry, I have found that there are some differences between the two groups in their view of the subject..
En ny diskussion kring religionsfriheten : Alternativ till religionsfrihetsbegreppet under Europakonventionen och Europeiska domstolen för de mänskliga rättigheterna
Freedom of religion or belief is indisputable in Human rights discourse, more discussed is exactly what it is that is included in the concept of freedom of religion or belief (in Swedish: religionsfrihet). This thesis focuses on the freedom of religion or belief in a European context, in particular on the European court of human rights and article 9 in the European convention for human rights. Some criticism has been directed against the Court to the effect that its practice and verdicts don't answer to the pronounced desire to develop a pluralistic and inclusive form of freedom of religion or belief.My aim is to examine, analyse and test three different theories, which all try to develop alternatives to the expression freedom of religion or belief, in relation to six verdicts from article 9 in Europe convention. My basic purpose is to try to find new ways of talking about freedom of religion or belief that might lead to a more inclusive, pluralistic and equal interpretation of that concept.The three theories wich I use are elaborated by Richard Amesbury (associate professor at Claremont school of Theology); Hugo Strandberg (TD at Åbo Akademi) and Eberhard Herrmann (professor in philosophy of religion at Uppsala University); and Martha Nussbaum (professor of law and ethics at the University of Chicago). The six cases from the European court are: X v.
Prediktion av villapris och dess faktorers inverkan.
A villas price depends on several important factors. By statistical data, a mathematical multiple regression model was modeled. The model has important explanatory variables such as living space, renovation year and standard points has been taken into consideration, in order to assess their impact on the final price for private homes.By using a statistical program,Minitab 16, the final model was selected with eight explanatory variables. The regression for this model explains up to 67.3 % of the variation on the final price.The results showed percentage wise that the standard points had the greatest impact on the price, there after renovation year and then living space..
Profitability and competitiveness of grain handling at farm level
The Swedish agricultural sector is currently experiencing substantial structural changes, where the number of agricultural enterprises continuously decreases and the average farm size increases. In order to maintain competitiveness, it is important to be aware and adapt to changes concerning the surroundings of the company (Johnson et al., 2011). Agricultural commodity prices sharply fluctuate on the global market in recent years, affecting the profitability of farmers. High volatility market requires tools to reduce price variations and increases the need of decision-making (Bouder & Beth, 2003). Farm-based grain handling facilities increases the sale options regarding agricultural commodities; a flexible strategy to get additional compensation for the storing the grain produced on the farm (Edling, 2002; Edwards, 2013).
Lärobokens roll i matematikundervisningen. : Allmändidaktisk tillämpning av van Hieles teorier vid introduktion av algebra.
Detta arbete är en textanalys av hur några svenska läroböcker i matematik introducerar algebra speglat i van Hieles teorier om tankenivåer vid inlärning. Van Hieles teorier poängterar språket som kunskapsbärare i matematik vilket går som en röd tråd genom analysen. Generellt börjar läroböckerna på van Hieles tankenivå 3. Enligt van Hieles teorier borde undervisningen i algebra börja på nivå 1, vilket då blir lärarens uppgift att göra utan stöd av matematikboken. Förslag på arbetssätt för nivå 1 och 2 ingår..
Japansk skräckfilm ? en kontemplativ succé?
Japanese horror film has since the late 1990: ies been extremely successful. The success could probably, at least partly, be due to the Japanese narrative style (which in my own opinion is quite suitable and effective in horror films). In what way does the Japanese narrative tradition work in matter of expression? My results point towards a narrative discrepancy between J-horror and American horror film, possibly due to the Japanese narrative tradition ? a narrative tradition under the influence of various forms of ancient Japanese theatre and general Japanese culture..
Efter pesten : om återhämtningen efter pestepidemin på 1710-talet i Skåne
From 1710 to 1713 the plague raged through the Swedish province of Scania. Other studies have been made on how the disease affected the society during the epidemic. This study tries to focus on the recovery afterwards. How did the population and the farmsteads recover after the plague? Statistics from parish registers and cameral records show interesting patterns in the demography, and that the recovery was far from complete 1720.
Isaac Newton och den matematiska naturfilosofin
In several scientific and technical educations today we meet mathematical studies in differential- and integral calculus. The classic mechanics is a foundation for the physics and it has made it possible for today's technical developments that we in our everyday life meet and make use of. The intention for this essay is to give a picture of the person behind this discoveries that changed the science and the world. Besides the purpose to bring the reader on a journey through Isaac Newton's life the main intention is to give an understanding of the way he discovered the binomial theorem, the differential- and integral calculus, the numerical methods Newton-Raphson's and Newton's interpolation-polynomial, Newtons identities and his classification of third-degree curves and elliptic curves. A derivation of Kepler's first law is also included..

Växtinventering och skötselåtgärder : en studie av Rektorsgårdens trädgård i Uppsala
The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.
