In 1793, the British government embarked on a war against Revolutionary France that few expected would last twenty-five years and engulf all of Europe. Radical French policies provided an opportunity for William Pitt, the British prime minister, to endeavor to cobble a European alliance, including a number of Mediterranean states. These efforts never progressed beyond theory and negotiations because of conflicted policy and tension between the British diplomatic corps and Royal Navy over the strategic goals in the region. With diplomats focused on coalition building and military commanders focused on national objectives, British efforts never congealed into a unified effort to defeat Revolutionary France.

The overarching goal of this research is to establish a successful forum for a transition from the existing paradigm of managing wastewater infrastructure to a more sustainable paradigm that achieves a more efficient utilisation of wastewater assets. A transitioning approach to support a more efficient utilisation of surface water and wastewater assets and infrastructure is proposed and developed. The determined transitioning approach possesses key stages namely developing the arena, developing the agenda, case study, and monitoring. The case study stage investigates a drainage utility identifying their improvement drivers, the removal of surface water through detailed drainage modelling and the financial examination of the costs incurred under the various scenarios conducted. Understanding the implications of removing/attenuating surface water from the network is improved through obtaining data by detailed drainage modelling. Infoworks software is used to investigate and assess the current and future operational scenarios of a wastewater system operating over one calendar year. Modelling scenarios were conducted removing surface water from selected areas focusing on the volumes requiring pumping and durations of pumping station(s) operation prior to treatment during storm conditions. The financial implication of removing surface water in combined sewer systems is examined in three main components. Firstly the costs of electricity incurred at the single sewage pumping station (SPS) investigated during the various scenarios modelled require to be addressed. Secondly the costs to retrofit sustainable urban drainage system (SUDS) solutions needs to be identified. Thirdly the implications of removing surface water for the drainage utility at the national level and the potential saving for householder’s committing to a surface water disconnection rebate scheme. When addressed at the macro level i.e., with over 2,100 pumping stations, some operating in sequence and contained within one drainage utility annually treating 315,360 megalitres the significance of the same multiple quantifiable and intangible benefits becomes amplified. The research aims, objectives and findings are presented to the identified and convened stakeholders. The transitioning approach developed encourages positive discourse between stakeholders. The level of success of the transitioning approach determined is then tested using a quantitative methodology through the completion of questionnaires. From the questionnaires completed the respondents unanimously agreed that surface water flows should be removed as well as reduced from the combined sewer system. The respondents agreed that the removal of surface water from a typical combined sewer system is justified by applying a transitioning approach focusing on the energy consumption required to pump increased volumes during storm events. This response is significant based upon the economic evidence and is contrary to the respondents previous position that finance was their most influencing factor. When provided with other potentially available benefits the respondents were even more supportive of the justification to remove surface water from the combined sewer system. The combined findings of the work presented in this thesis provide further justification that the transitioning approach applied to the removal of surface water from a typical combined sewer system, as determined in this research has been successful.

Cotutelle entre l'Université de Montréal et l'Université catholique de Louvain / Les batteries aux ions lithium (BIL) sont considérées comme la technologie la plus prometteuse en matière de stockage d’énergie. Elles possèdent les plus hautes densités d’énergie connues, permettant la miniaturisation constante des appareils électroniques commercialisés. La recherche dans le domaine des BIL s’est plus récemment tournée vers leur implémentation dans les véhicules électriques, qui nécessitera de plus hautes densités d’énergie et de puissance . Une manière concrète d’augmenter la densité d’énergie d’une BIL est d’en augmenter le voltage de cellule. Pour se faire, la nouvelle génération de batteries sera composée de matériaux d’électrode positive à haut potentiel (tel que LiMn1.5Ni0.5O4 avec un potentiel de 4.7 V vs. Li+ /Li) et de lithium métallique en électrode négative. Néanmoins, l’introduction de ces matériaux d’électrode positive à haut potentiel est limitée par la stabilité électrochimique de l’électrolyte liquide conventionnel, composé d’un sel de lithium et de solvants organiques (typiquement LiPF6 + EC/DEC), qui s’oxyde autour de 4.2 V vs. Li+/Li , . L’utilisation du lithium métallique comme électrode négative est entravée par la nature liquide de l’électrolyte conventionnel, qui n’offre pas assez de résistance mécanique pour empêcher la formation de dendrites de lithium, causant à terme le court-circuit de la batterie. De tels courts-circuits présentent un risque d’incendie car les électrolytes liquides sont composés de solvants organiques inflammables à basse température, posant un sérieux problème de sécurité. Les électrolytes solides, de type céramique ou polymères, sont développés en alternative aux électrolytes liquides. Ils ne contiennent aucun solvant inflammable et sont stables à haute température. Ils constituent l’élément clé d’une nouvelle génération de batteries au lithium dite batteries au lithium tout-solide. Ces dernières sont développées pour répondre à des attentes élevées en termes de sécurité, de stabilité et de haute densité d’énergie. Les électrolytes solides doivent satisfaire un certain nombre d'exigences avant de pouvoir être commercialisés, notamment posséder une conductivité ionique élevée, une large fenêtre de stabilité électrochimique et une conductivité électronique négligeable. Ces propriétés constituent les critères les plus importants à prendre en compte pour la sélection de matériaux d’électrolytes solides. Cependant, on remarque dans la littérature que la majorité des études se concentre sur la conductivité ionique des électrolytes solides, reléguant au second plan l’exploration de leurs stabilité électrochimique et conductivité électronique. La fenêtre de stabilité électrochimique a longtemps été annoncée comme étant très large chez les électrolytes solides céramiques (au moins de 0 à 5 V vs. Li+/Li). Néanmoins, des études plus récentes tendent à démontrer que la valeur de cette fenêtre dépend grandement de la méthode électrochimique utilisée pour la mesurer, et qu’elle est de surcroit souvent surestimée. Dans ce contexte, le premier objectif de cette thèse a été de développer une méthode pertinente pour déterminer la fenêtre de stabilité des électrolytes solides avec précision. Cette méthode a été optimisée et validée sur des électrolytes solides céramiques phare comme Li1.5Al0.5Ge1.5(PO4)3, Li1.3Al0.3Ti1.7(PO4)3 et Li7La3Zr2O12. Quant à la conductivité électronique, elle est rarement étudiée dans les électrolytes solides, qui sont considérés comme isolants électroniques compte tenu de leur large bande interdite. Cela dit, de récentes études à ce sujet prouvent que malgré leur bande interdite, les électrolytes solides peuvent générer de la conductivité électronique par le biais de défauts, et que celle-ci, même faible, peut éventuellement mettre l’électrolyte en échec. Pour cette raison, le second objectif de ce projet de thèse a été d’explorer la formation de défauts dans les électrolytes solides afin de déterminer leur effet sur la génération de conductivité électronique. Pour avoir une vision d’ensemble, les premiers-principes ont été utilisés pour étudier six électrolytes solides largement utilisés notamment LiGe2(PO4)3, LiTi2(PO4)3, Li7La3Zr2O12, et Li3PS4. / Lithium-ion batteries (LIBs) are considered the most promising energy storage technology. LIBs electrode materials have the highest known energy densities, allowing the constant miniaturization of commercial electronic devices. Research in the field of LIBs has more recently turned to their implementation in electric vehicles, which will require higher energy and power densities . A concrete way to increase the energy density of LIBs is to increase the cell voltage. To do so, the new generation of batteries will be composed of high potential positive electrode materials (such as LiMn1.5Ni0.5O4 with a potential of 4.7 V vs. Li+/Li) and metallic lithium in the negative electrode. Nevertheless, the introduction of these high potential positive electrode materials is limited by the electrochemical stability of conventional liquid electrolytes, composed of a lithium salt and organic solvents (LiPF6 + EC/DEC), which gets oxidized around 4.2 V vs. Li+/Li , . The use of metallic lithium as the negative electrode is also hindered by the liquid nature of the conventional electrolyte, which does not offer enough mechanical resistance to prevent the formation of lithium dendrites, ultimately causing a short-circuit of the battery. Such short-circuits are likely to lead to thermal runaway because liquid electrolytes are composed of organic solvents that are flammable at low temperature, posing a serious safety issue. Solid electrolytes, based on ceramics or polymers, are developed as an alternative to liquid electrolytes. They contain no flammable solvents and are stable at high temperatures. They are the key element of a new generation of lithium batteries called all-solid-state lithium batteries. These are developed to meet high expectations in terms of safety, stability and high energy density. Solid electrolytes must satisfy a number of requirements before they can be commercialized, including possessing a high ionic conductivity, a wide electrochemical stability window and negligible electronic conductivity. These properties are the most important criteria to consider when selecting solid electrolyte materials. However, the majority of studies found in the literature focuses on the ionic conductivity of solid electrolytes, overshadowing the exploration of their electrochemical stability and electronic conductivity. The electrochemical stability window has long been reported to be very wide in ceramic solid electrolytes (at least from 0 to 5 V vs. Li+/Li). Nevertheless, more recent studies tend to show that the value of this window depends greatly on the electrochemical method used to measure it, and that it is often overestimated. In this context, the first objective of this thesis was to develop a relevant method to determine the stability window of solid electrolytes with precision. This method was optimized and validated on flagship ceramic solid electrolytes such as Li1.5Al0.5Ge1.5(PO4)3, Li1.3Al0.3Ti1.7(PO4)3 and Li7La3Zr2O12. As for the electronic conductivity, it is scarcely studied in solid electrolytes, which are considered as electronic insulators given their wide band gaps. That being said, more recent studies on this subject proved that despite their band gap, solid electrolytes can generate electronic conductivity through defects, and that electronic conductivity, even if it is weak, can eventually cause the failure of the electrolyte. For this reason, the second objective of this thesis project was to explore the formation of defects in solid electrolytes in order to determine their effect on the generation of electronic conductivity. To get a better overview, first-principles were used to investigate six widely used ceramic solid electrolytes, including LiGe2(PO4)3, LiTi2(PO4)3, Li7La3Zr2O12, and Li3PS4.

On 1 February 1793, the National Convention of Revolutionary France declared war on Great Britain and the Netherlands, expanding the list of France's enemies in the War of the First Coalition. Although British Prime Minister William Pitt the Younger had predicted fifteen years of peace one year earlier, the French declaration of war initiated nearly a quarter century of war between Britain and France with only a brief respite during the Peace of Amiens. Britain entered the war amid both a nadir in British diplomacy and internal political divisions over the direction of British foreign policy. After becoming prime minister in 1783 in the aftermath of the War of American Independence, Pitt pursued financial and naval reform to recover British strength and cautious interventionism to end Britain's diplomatic isolation in Europe. He hoped to create a collective security system based on the principles of the territorial status quo, trade agreements, neutral rights, and resolution of diplomatic disputes through mediation - armed mediation if necessary. While his domestic measures largely met with success, Pitt's foreign policy suffered from a paucity of like-minded allies, contradictions between traditional hostility to France and emergent opposition to Russian expansion, Britain's limited ability to project power on the continent, and the even more limited will of Parliament to support such interventionism. Nevertheless, Pitt's collective security goal continued to shape British strategy in the War of the First Coalition, and the same challenges continued to plague the British war effort. This led to failure in the war and left the British fighting on alone after the Treaty of Campo Formio secured peace between France and its last continental foe, Austria, on 18 October 1797.

In 2004 Troy was released in movie theatres worldwide and almost immediately sparked up discussions on film’s relation to the ancient epic of Homer.  The main purpose of this paper is to see the connection between Troy and Homer’s The Iliad – motion pictures’ only officially credited source of inspiration. By using comparative method and intertextual approach I try to see how a literary piece, for centuries recited and cherished by the highest academic circles is remodelled to fit the taste of a mass public. How The Iliad mutates to be a marketable product.    I discuss the changes of the plot that were introduced in Troy and try to see those changes as an outcome of mutation process. Apart from the plot, the notion of a hero is also discussed: how the definition of hero changed through time? To illustrate the changes, two main heroes – Achilles and Hector are discussed, yet again using the comparative method.    By approaching Troy and The Iliad as two separate cultural products (I did not view Troy as a documentary on The Iliad) I was able to connect them. I could see that the essence of the literary work and the film appears to be the same. It shows that the ancient Greek values, especially those, related to warfare and heroism, have definitely survived long enough to penetrate the modern thought.

The work examines the antislavery writings of Francis Wayland (1796-1865). Wayland pastored churches in Boston and Providence, but he left his indelible mark as the fourth and twenty-eight year president of Brown University (1827-1855). The author of numerous works on moral science, economics, philosophy, education, and the Baptist denomination, his administration marked a transitional stage in the emergence of American colleges from a classically oriented curriculum to an educational philosophy based on science and modern languages. Wayland left an enduring legacy at Brown, but it was his antislavery writings that brought him the most notoriety and controversy. Developed throughout his writings, rather than systematically in a major work, his antislavery views were shaped and tested in the political and intellectual climate of the antebellum world in which he lived. First developed in The Elements of Moral Science (1835), he tested the boundaries of activism in The Limitations of Human Responsibility (1838), and publicly debated antislavery in Domestic Slavery Considered as a Scriptural Institution (1845). The political crisis from the Mexican-American War through the Kansas-Nebraska Act heightened Wayland’s activism as delineated in The Duty of Obedience to the Civil Magistrate (1847), his noncompliance with the Fugitive Slave Law, and his public address on the Kansas-Nebraska Bill (1854). In 1861 he became a committed Unionist. I argue that Francis Wayland was a mediating figure in the controversy between abolitionists and proslavery apologists and that his life was a microcosm of the transition that many individuals made from moderate antislavery to abolitionism. Wayland proved unique in that he was heavily coveted by Northern abolitionists who sought his unconditional support and yet he was respected by Southerners who appreciated his uncondemning attitude toward slaveholders even while he opposed slavery. I argue that Wayland’s transition from reluctant critic to public activist was not solely due to the political sweep of events, but that his latter activism was already marked in his earlier work. Most importantly, his life demonstrated both the limits and possibilities in the history of American antislavery.
