Syftet med denna uppsats är att undersöka och jämföra Djävulens funktion i dagens mest lättillgängliga och populära mediagenrer. I studien redogörs hur bilden av Djävulen uppstått med nedslag i Gamla testamentet fram till upplysningen. Mot denna bakgrund tolkas och analyseras hur och om denna gestalt återfinns i dagens mediasamhälle, med inriktning på filmerna Terror på Elm Street och 2012, tv-serien Lost och romanen Frankenstein av Mary Shelley. Huvudresultatet visar på att en kamp mellan det goda och det onda troligtvis all­tid kommer att förekomma och medan djävulsgestalten i och med upplysningen tappar infly­tande i kristendomen återfinns denne i diverse film, böcker och serier.

Ophiostoma novo-ulmi is the causal agent of Dutch elm disease (DED) which has had a severe impact on the urban landscape in Canada. This research program focused on developing molecular genetic strategies to control this pathogenic fungus. The first strategy involved the development of RNA interference (RNAi) for the down-regulation of genes involved in pathogenicity. An efficient RNAi cassette was developed to suppress the expression of the endopolygalacturonase (epg1) locus which encodes a cell-wall degrading enzyme. This epg1-RNAi cassette significantly reduced the amount of polygalacturonase activity in the fungus and resulted in almost complete degradation of epg1 mRNA. The need for a native promoter to selectively down-regulate specific gene loci was addressed by developing a carbon-catabolite regulated promoter (alcA) to drive the expression of the epg1-RNAi cassette. The expression of an alcA-driven epg1-RNAi cassette resulted in the down-regulation of epg expression under glucose starvation but normal levels of expression in high glucose. The expression could therefore be controlled by culture conditions. The second strategy explored the potential of using dsRNA viruses to vector disruptive RNAi cassettes. An isolate of O. novo-ulmi strain 93-1224 collected in the city of Winnipeg, was infected by two dsRNA mitoviruses which upon sequence characterization were named OnuMV1c and OnuMV7. To assess the transmissibility of this dsRNA virus the infected isolate 93-1224 was paired with three naive isolates of the related fungi O. ulmi and O. himal-ulmi. Through the use of nuclear and mitochondrial markers it was determined that the virus OnuMV1c may not rely on mitochondrial fusion for transmission but may have a cytoplasmic transmission route. This investigation of gene expression and manipulation has provided tools to help understand gene regulation in O. novo-ulmi. It has also added to our knowledge of mitoviruses, their transmission and potential use as a biological control. By enhancing our understanding of transmissible hypovirulence this work contributes to efforts to develop a new approach to target DED as well as a potential model for the control of other fungal diseases. / Graduate / 0307 / 0306 / 0369 / jscarneiro@hotmail.com

Adolescents are especially vulnerable to image-based messages, which place them directly in line with the lifestyle messages presented in numerous alcohol advertisements. Research has shown that teenagers encounter alcohol advertisements from a variety of sources, prompting concern over the consequences of exposure and the risks associated with teen drinking. Warning messages contained within these alcohol advertisements are often vague in their wording and targeted to promote responsible drinking among adults, making them wholly inadequate for teen deterrence. This thesis explores the problems with current alcohol responsibility messages when dealing with teens, and proposes the development of new, modified messages, that are more direct and consequence-based. The Elaboration Likelihood Model of persuasion was used to describe teen processing of alcohol warning messages, and eye-tracking technology was used to determine how this processing can be examined visually. The purpose of this research was to aid in the development of new messages that have been modified by type size, type contrast, and message content (a 2x2x2 factorial design). Results indicated that modifying message content to include direct language and a consequence enhances visibility and attention to alcohol responsibility messages. Larger type and higher contrast can be applied to the message to further enhance visibility, but the change in attention for these factors was shown to be minimal and nonsignificant. Overall, the greatest power lies in changing the message itself, irrespective of all other variables.

Next-generation and present fusion devices such as the Joint European Torus (JET) aim for plasma operations in H-mode, a plasma regime with high confinement and low loss of energy and fuel that results from a barrier for heat and particle transport at the plasma edge, the pedestal. Due to steep gradients of the density, temperature and pressure profiles, the pedestal experiences instabilities called Edge-localized-modes (ELMs) which lead to large fluxes of heat and particles that might damage machine components. A theoretical value for the critical threshold for the pressure gradient is determined by the Peeling-Ballooning (PB) model. Although this model has been rather reliable, experiments have shown a discrepancy between the experimental pedestal pressure gradient and the critical pressure gradient determined by the model. A number of experimental gradients were significantly lower than the predicted gradients. The mechanisms responsible for this discrepancy are not fully understood yet. The present hypothesis identifies the relative shift between the positions of the temperature and density pedestals and neutral pressure as key parameters, related to input power and gas dosing among other engineering parameters. Further impact could arise from the assumption of equal ion and electron temperature and the neglecting of the plasma rotation (velocity). In order to investigate this issue more thoroughly, JET established a comprehensive database containing pedestal characteristics. As a part of this work, a software has been implemented to visualize the data since such a tool did not exist yet. The tool enables the plotting of pedestal related parameters while specific data subsets can be selected or neglected. The tool has been used to investigate the impact of ion temperature and plasma rotation on the discrepancy between the theoretical and experimental critical gradients. Hereby, many relevant parameters needed to be constrained to observe an isolated impact of ion temperature and plasma rotation. The results of this investigation support the hypothesis that mainly the relative shift affects the discrepancy between experimental and predicted pressure gradient, but that also the use of experimental ion temperature can contribute to reduce the discrepancy. / Nästa generations och nuvarande fusionsanordningar, såsom Joint European Torus (JET), syftar till plasmaoperationer i H-läge, en plasmaregim med hög inneslutning och låg förlust av energi och bränsle som är ett resultat av en barriär för värme­ och partikeltransport vid plasmakanten, piedestalen. På grund av branta gradienter i densitets-, temperatur- och tryckprofilerna, är piedestalen instabil. Instabiliteten kallas Edge-Localised-Mode (ELM) och leder till stora flöden av värme och partiklar som kan skada maskinkomponenter. En kritisk tröskel för tryckgradienten bestäms av modellen Peeling-Ballooning (PB). Även om denna modell har varit ganska tillförlitlig, har experiment visat en diskrepans mellan den experimentella piedestaltryckgradienten och den kritiska tryckgradienten som bestäms av modellen. Ett antal experimentellt uppmätta kritiska gradienter är signifikant lägre än de förväntade enligt modellen. De mekanismer som ligger bakom denna diskrepans är ännu inte helt klarlagda. Den nuvarande hypotesen identifierar skillander i pos positionen av temperature- och täthetspiedestalen, samt trycket från neutraler som nyckelparametrar, relaterade till inmatad effekt och gasdosering bland andra ingenjörparametrar. Ytterligare påverkan kan uppstå genom antagandet att joner och elektroner har samma temperatur och försummandet av plasmarotationen. För att undersöka denna fråga mer ingående upprättade JET en omfattande databas med piedestalegenskaper. Som en del av detta arbete har en programvara implementerats för att visualisera data eftersom ett sådant verktyg inte funnits tidigare. Verktyget möjliggör plottning av piedestalrelaterade parametrar medan specifika data delmängder kan väljas eller väljas bort. Verktyget har använts för att undersöka inverkan av jontemperatur och plasmarotation på diskrepansen mellan teoretiska och experimentell kritiska tryckgradienten. För denna analys behövde många relevanta parametrar begränsas för att observera en isolerad påverkan av jontemperatur och plasmarotationen. Resultaten av denna undersökning stödjer hypotesen att det relativa skiftet främst påverkar diskrepansen mellan experimentell och förutsedd tryckgradient men att även användning av experimentell jontemperatur kan bidra till att minska diskrepansen.

Studies on Canadian Army military intelligence remain sparse in Canadian military historiography. This study is unique in that it focuses on the development, doctrine, and influence of intelligence within the I Canadian Corps throughout the Liri Valley battles during the Italian Campaign. It will be argued that I Canadian Corps intelligence achieved notable overall success in helping to break the Hitler Line by providing comprehensive and relatively up-to-date information on enemy dispositions and strengths which helped commanders and staff planners properly prepare for the operation. This success was attributable to three main factors: excellent intelligence personnel selection and training; the successful mentorship of I Canadian Corps intelligence by Eighth Army's intelligence cadre; and the overall effectiveness of 1st Canadian Infantry Division's intelligence organization which had been in the Mediterranean theatre since July 1943. Notwithstanding these successes, a number of faults within the Canadian Corps intelligence system must also be explained, including the poor performance of 5th Canadian Armoured Division's intelligence organization during the pursuit up the Liri–Sacco Valleys, and the mediocre execution of Corps counter-battery and counter-mortar operations. This study will demonstrate how an effective intelligence organization must augment existing army doctrine and how it can mitigate, though not completely eliminate, battlefield uncertainty. Further, it will also demonstrate that a comprehensive lessons-learned process must be undertaken to continually refine existing intelligence doctrine and procedures, with frequent training programs inculcating personnel in this doctrine. Taken as a whole, this study is unique as it is one of only several studies devoted solely to developing a greater understanding of a little-understood, and often forgotten, staff function within the Canadian Army during the Second World War.
