I will write about product placement in film from a Swedish point of view. This entails writing about Swedish films with different types of product placements, not only how they are done but also discuss how they succeed from a sales perspective. In my earlier work I have written about the product placement of watches. In this thesis I focus on the film series about the Swedish agent Carl Hamilton, since here you can see how Swedish film has developed during the past 30 years with regard to product placements. Both world politics and the concrete placements are illustrated in a clear way. In such an international context it is also of value to compare recent Hollywood remakes of a Swedish film, in this case Män som hatar kvinnor that was turned into The Girl with the Dragon Tattoo. Both are based on the same book by the Swedish author Stieg Larsson, Män som hatar kvinnor.

Killbuck-Mud Creek Subwatershed (KBMC) stream channels have been extensively modified to facilitate the drainage for agricultural purposes. To identify the feasibility of stream restoration, the natural conditions of the subwatershed were estimated from the current basin morphometry, hydrology, and channel sediment load. The historic conditions for KBMC were assembled from literature and remote sensing to tabulate the conditions controlling the drainages through time. Using the Rosgen Classification of Natural Rivers the morphology of the natural streams was predicted.The dredged channels of KBMC follow glacial outwash channels. The glacial channels were silted in and hardwood forests added woody debris to create slow moving swampy conditions in the drainages. These conditions did not allow for agriculture prior to stream modifications. Only the installation of channel conditions not previously found in KBMC can be used as a stream restoration option, other management practices are suggested for the subwatershed. / Department of Geology

What is in common between the Kepler problem, a Hydrogen atom and a rotating black- hole? These systems are described by different physical theories, but much information about them can be obtained by separating an appropriate Hamilton-Jacobi equation. The separation of variables of the Hamilton-Jacobi equation is an old but still powerful tool for obtaining exact solutions. The goal of this thesis is to present the theory and application of a certain type of conformal Killing tensor (hereafter called concircular tensor) to the separation of variables problem. The application is to spaces of constant curvature, with special attention to spaces with Euclidean and Lorentzian signatures. The theory includes the general applicability of concircular tensors to the separation of variables problem and the application of warped products to studying Killing tensors in general and separable coordinates in particular. Our first main result shows how to use these tensors to construct a special class of separable coordinates (hereafter called Kalnins-Eisenhart-Miller (KEM) coordinates) on a given space. Conversely, the second result generalizes the Kalnins-Miller classification to show that any orthogonal separable coordinates in a space of constant curvature are KEM coordinates. A closely related recursive algorithm is defined which allows one to intrinsically (coordinate independently) search for KEM coordinates which separate a given (natural) Hamilton-Jacobi equation. This algorithm is exhaustive in spaces of constant curvature. Finally, sufficient details are worked out, so that one can apply these procedures in spaces of constant curvature using only (linear) algebraic operations. As an example, we apply the theory to study the separability of the Calogero-Moser system.

The western embayment of Lake Ontario, Hamilton Harbour, is one of the most polluted sites in the Laurentian Great Lakes and in recent years has seen a reoccurrence of cyanobacterial blooms. This study uses a multidisciplinary approach to examine the presences of toxic Cyanobacteria in the harbour in order to gain insight into these recurrent blooms. Microscopic analyses of phytoplankton samples collected during the 2009 summer-fall sampling season from two locations within the harbour showed the spatial and seasonal diversity of the contemporary cyanobacterial community. Microcystis colonies relative abundances in relation to total algal numbers were estimated. The lowest and highest relative abundances of Microcystis in the phytoplankton population were 0.6% and 9.7%, respectively, and showed seasonal variability between stations. Fourteen cyanobacterial genera comprising six families and three orders were identified and for which the most abundant filamentous genera during the summer-fall sampling season were Planktothrix, Aphanizomenon and Limnothrix. Potential microcystin producers Microcystis, Planktothrix, Aphanizomenon and Dolichospermum were also present and during the sampling period Microcystis was recorded at both stations on all dates, however, its relative abundance was below 10 % throughout the study period. The composition and abundance of filamentous cyanobacteria were observed to be positively statistically correlated to water quality environmental parameters dissolved nitrates (NO3/NO2), dissolved inorganic carbon (DIC), and conductivity. Redundancy analysis (RDA) found that 53.35% total variance of Aphanizomenon was correlated to low water column NO3/NO2 and conductivity, and higher water column DIC. 58.13% of the relative abundance of Planktothrix was correlated to high concentrations of dissolved nitrates, while 51.69% of total variance of Limnothrix was correlated to higher DIC and lower water column dissolved nitrate concentrations. Information about past cyanobacterial communities was obtained from the sediment core analysis, using paleolimnological and modern molecular methods. The age of the 100.5 cm long sediment core retrieved from the deepest part of Hamilton Harbour was established to be 140 years (1869-2009), using the Constant Rate of Supply (CRS) 210Pb age model. This age was not sufficient to provide information of harbour’s environmental conditions, presence of the blooms, and triggers for their occurrence before European settlement in the area. Results of the HPLC analysis of fossil pigments indicated that the dominant members of the algal community have not changed over the 140 years and that cyanobacteria were regular members of the phytoplankton community. The composition of the major chlorophyll pigments indicated high presence of Chlorophyta and Bacillariophyta in the harbour at all times. The main algal groups identified on the basis of marker pigments presence, besides the Chlorophyta and Bacillariophyta, were the Dinophyta and the Cryptophyta. The presence of a scytonemin derivative, compound B, indicated that cyanobacterial blooms were occurring in past, before the first officially recorded blooms in the 1960s. Cyanobacterial pigments presence indicated that Cyanobacteria have been a regular but not dominant feature of Hamilton Harbour phytoplankton in the past. To our knowledge, this study is the first one examining fossil pigments from Hamilton Harbour. Results of the PCR-DGGE molecular analysis of 16S rRNA-V3 gene fragments from sedimentary DNA revealed the presence of thirteen cyanobacterial genotypes. The temporal change in the cyanobacterial community composition was indicated by the increasing number of species over time, from the oldest to the most recent sediment layers. The deepest sediment strata showed the lowest number (two bands) and intensity of bands. The most recent sediment layer had the greatest numbers (11) and intensity of bands. This increased diversity indicated changing environmental conditions in the harbour, primarily nutrient pollution and worsening water quality. Results of the PCR-DGGE molecular analysis of mcyE-AMT gene fragments showed that Microcystis aeruginosa and Planktothrix rubescens were two microcystin producers present in Hamilton Harbour over the last 80 years. The persistent presence and resilience of these two genera indicated a more serious and longer-term issue of toxic blooms than previously recognized. Historical records show that noticeable anthropogenic impact on Lake Ontario environment has been measurable since the 1780s, the first dramatic impact on the Lake Ontario watershed was evident from the mid1880s, the earliest evidence of eutrophication in the lake occurred between 1820 and 1850, while human induced environmental changes in Hamilton Harbour date back ca. 350 years. In the 1960s, cyanobacterial blooms were first officially recognized in the harbour and the lower Great Lakes. The present research is the first report of the mcyE module and AMT domain of microcystin genes being amplified from sediment of North American lakes, and showed that toxic Cyanobacterial have been regular members of Hamilton Harbour phytoplankton community for almost a century. This research considerably deepened the knowledge of the past toxic cyanobacterial blooms in Hamilton Harbour and their possible causes. It also showed that in the absence of historical records, both the PCR-DGGE method and the mcyE-AMT gene may be used for reconstruction of the past toxic blooms not only in the Laurentian Great Lakes, but also in other aquatic regions of the world impacted by toxic cyanobacterial blooms. Also, it demonstrated the utility of the combined molecular and paleolimnological analyses, which might become a useful tool in the determination of the bloom causes factors and in the mitigation of the future production of toxic blooms.

Dans cette thèse, nous étudions les solutions des équations Hamilton-Jacobi. Plus précisément, nous comparons la solution de viscosité, obtenue comme limite de solutions de l'équation perturbée par un petit terme de diffusion, et la solution minmax, définie géométriquement à partir d'une fonction génératrice quadratique à l'infini. Dans la littérature, il y a des cas bien connus où les deux coïncident, par exemple lorsque le hamiltonien est convexe ou concave, le minmax pouvant alors être réduit à un min ou un max. Mais les solutions minmax et de viscosité diffèrent en général. Nous construisons des "minmax itérés" en répétant pas à pas la procédure de minmax et démontrons que, quand la taille du pas tend vers zéro, les minmax itérés tendent vers la solution de viscosité. Dans une deuxième partie, nous étudions les lois de conservation en dimension un d'espace par le méthode de "front tracking". Nous montrons que dans le cas où la donnée initiale est convexe, la solution de viscosité et le minmax sont égaux. Et comme application, nous décrivons sur des exemples la manière dont sont construites les singularités de la solution de viscosité. Pour finir, nous montrons que la notion de minmax n'est pas aussi évidente qu'il y paraît.

The problem of defining cycles in infinite graphs has received much attention in the literature. Diestel and Kuhn have proposed viewing a graph as 1-complex, and defining a topology on the point set of the graph together with its ends. In this setting, a circle in the graph is a homeomorph of the unit circle S^1 in this topological space. For locally finite graphs this setting appears to be natural, as many classical theorems on cycles in finite graphs extend to the infinite setting. A Hamilton circle in a graph is a circle containing all the vertices of the graph. We exhibit a necessary and sufficient condition that a countable graph contain a Hamilton circle in terms of the existence of Hamilton cycles in an increasing sequence of finite graphs. As corollaries, we obtain extensions to locally finite graphs of Zhan's theorem that all 7-connected line graphs are hamiltonian (confirming a conjecture of Georgakopoulos), and Ryjacek's theorem that all 7-connected claw-free graphs are hamiltonian. A third corollary of our main result is Georgakopoulos' theorem that the square of every two-connected locally finite graph contains a Hamilton circle (an extension of Fleischner's theorem that the square of every two-connected finite graph is Hamiltonian).

This thesis uses a web site as its primary format. Readers are invited to visit www.birthofaregiment.com. Financed by a wealthy Montreal businessman, the original regiment was very British in its make-up. The Patricia’s were recruited and trained separate from the Canadian Expeditionary Force. For the first year of the war, they fought in a British brigade, under British officers using British weapons. By 1919, the PPCLI were distinctly Canadian. The Patricia’s became the best known Canadian regiment and one of three retained in the permanent force. This thesis examines that remarkable transition, the changes wrought by the war and the mechanisms used to reinforce the unique image of the Patricia’s. It also tests several myths embodied in the histories of the Regiment against a database of over five thousand files of soldiers who served with the Patricia’s during the First World War. / Graduate

The urban landscape reflects the social, economic, and policy changes that have taken place in a community. The inner city has been previosly called a microcosm that indicates the changes that are occurring in society. The inner city can thus be studied to examine how it responds and adapts to economic change. This thesis asks in what ways are the historic and current economic transitions visible in Hamilton’s inner city landscape; and how do planning policies influence the emerging urban built form. The thesis examines select characteristics of the contemporary inner city derived from the literature (i.e. art and entertainment amenitites, recreational uses, residential revitalization, institutional uses, post-Fordist economy, decline in manufacturing activity, promotion of multi-modal transportation, sustainability policy, and statement place making) and their expected physical manifestations. The methods consist of a historical analysis and visual diagnosis that uses photographs and field notes in order to provide a bottom-up interpretation of downtown Hamilton’s changing urban landscape. There is evidence of arts-culture led rejuvenation of downtown Hamilton and the public realm. However, there is the challenge of promoting revitalization in a context of visual urban blight and the possibilities of policy-induced loss of employment lands.
