Because of its specific qualities, lithium is a key element for making lithium-ion batteries, which is of great relevance since the battery sector is the fastest growing user of lithium to date and with the transition towards a fully electrified transportation sector due to the current climate agenda and an even bigger increase in demand for lithium is anticipated for the coming decades. The two main sources for lithium to date are mines and brines, with brine water composing around 87 % of the world’s lithium reserves in terms of contained lithium. Salars, dominantly large salt flats in South America, provide the type of brine water that has a high concentration of lithium. These salars occur primarily in Argentina, Bolivia and Chile (the ABC-triangle), where solid lithium-compounds occur dominantly as evaporate minerals such as lithium carbonates. Lithium from salars is recovered with natural evaporation and salar-derived lithium-salts generally have a higher purity than lithium derived from pegmatite mining. However, the process of lithium extraction from salars much slower than mining lithium from pegmatite, although large amounts of energy are required and large amounts of waste rock material is produced in the process. Lithium also occurs in geothermal waters and in seawater, but at far lower concentrations then in pegmatites or salar brines, which thus requires large processing efforts to be economically attractive.The purpose of this study is to provide a modern update based on the lithium production data in metric tons from recent years and interpolate the lithium production for the remaining part of the century. Then I will assess the difference between the projections from the study by Vikström et al. 2014, that were previously used to estimate possible future production rates annually, and current production and availability estimates. To achieve this, the present study will compare the different sources of lithium all over the world, mainly hard rock and brine, with a focus on the geological aspects and the EU from a financial aspect. This thesis thus aims to assess future production trends based on most recent data on geological availability, which will be retrieved from The United States Geological Survey, and earlier forecasts with the purpose to investigate if and how previous forecasts will need to change in respect to various resource availability. The production data ranging from 1900 to 2010 from the previous study by Vikström et al., on which the previous forecast production is based on, is updated with data from 2011 to 2019. With the addition of the more recent data, a similar forecast projection will be made using the same mathematical models (logistic, Gompertz and Richards).

The study provides a theoretical account for the representation of apartheid in South African fiction. Narrative strategies employed in the post-apartheid novels The innocence of roast chicken (Richards, 1996), The smell of apples (Behr, 1996), All we have left unsaid (Case, 2006) and Thirteen cents (Duiker, 2011) reveal that depictions of the past contribute to narrative structure and the production of meaning. Genettean temporal relations, namely narrative order, duration and frequency are a systematic method to analyse the selected novels, since it enables a contrast between the narrative past as the histoire, and the narrative present as the récit. Retrospective events are constructed as memories, thereby are complemented by Bergson’s psychological and philosophical theory in the analysis and interpretation of the dualistic interaction between the apartheid and post-apartheid temporal centres adopted within the novels. The representation of apartheid may be seen as sub-themes and time as configurations of temporal zones. / Afrikaans & Theory of Literature / M.A. (Theory of Literature)

Cette thèse vise à étudier expérimentalement, analytiquement et numériquement, les conséquences de variations et d'oscillations hydrodynamiques à forte variabilité temporelle en milieux poreux partiellement saturés. Les problèmes que nous étudions comportent des surfaces libres tant à l'extérieur qu'à l'intérieur des milieux poreux, celles-ci étant définies comme des isosurfaces de pression d'eau égale à la pression atmosphérique (Pwater = Patm). Les différentes études expérimentales réalisées en laboratoire sont, respectivement : une expérience d'imbibition dans une boite à sable avec effets capillaires importants; la transmission d'oscillations de la surface libre à travers un massif sableux intercalaire dans un petit canal à houle (IMFT, Toulouse); l'étude de la dynamique et de la propagation des oscillations des niveaux d'eau dans un grand canal à houle (HYDRALAB, Barcelone), partiellement recouvert d'un fond sableux incliné, avec mesures de niveaux d'eau en pleine eau et sous le sable, et mesures du fond sableux (érosion/dépôts). Pour les études théoriques, nous avons développés des solutions analytiques linéarisées. Un exemple de problème traité analytiquement est: l'équation linéarisée de Dupuit-Boussinesq (D-B) transitoire à surface libre, en hypothèse d'écoulements plans et vidange/remplissage instantané : oscillations forcées, transmission et dissipation d'ondes à travers une boite à sable rectangulaire. Nous avons aussi développé une solution de l'équation faiblement non linéaire de Dupuit- Boussinesq (D-B) pour étudier le problème d'imbibition avec variation abrupte du niveau d'eau amont (suivi temporel du front de saturation). Nous avons pu étudier les différents types de problèmes transitoires liés aux expériences citées plus haut par simulation numérique. En particulier, nous avons simulé des écoulements partiellement saturés et insaturés, en coupe verticale, à l'aide d'un code de calcul (BIGFLOW 3D) qui résoud l'équation de Richards généralisée en régime transitoire. Nous avons ainsi étudié numériquement en régime non saturé, l'expérience d'imbibition dans un sable initialement sec à frontières verticales (IMFT sandbox), puis l'expérience de propagation d'ondes dans le grand canal à houle de Barcelone (laboratoire HYDRALAB) comportant une plage de sable inclinée, avec un couplage complètement intégré entre les zones micro-poreuse (sable) et “macro-poreuse” (pleine eau). Pour analyser les résultats de cette dernière expérience et les comparer aux simulations, nous avons utilisé plusieurs méthodes de traitement et d'analyse des signaux : analyse de Fourier (spectres de fréquences) ; ondelettes discrètes multi-résolution (Daubechies) ; analyses corrélatoires simple et croisée. Ces méthodes sont combinées avec des méthodes de préfiltrage pour estimer dérives et résidus (moyennes mobiles ; ondelettes multi-résolution). Cette analyse des signaux a permis de comprendre et quantifier la propagation à travers une plage de sable. Au total, les différentes approches de modélisation mis en oeuvre, associé à des procédures de calage en situation de couplage transitoire non linéaire ont permis de reproduire globalement les phénomènes de propagation de teneur en eau et de niveau d'eau dans les différentes configurations étudiées. / This thesis aims at investigating experimentally, analytically and numerically, the consequences of hydrodynamic variations and oscillations with high temporal variability in partially saturated porous media. The problems investigated in this work involve “free surfaces” both outside and inside the porous media, the free surface being defined as the “atmospheric” water pressure isosurface (Pwater = Patm). The laboratory experiments studied in this work are, respectively: Lateral imbibition in a dry sand box with significant capillary effects; Transmission of oscillations of the free surface through a vertical sand box placed in a small wave canal (IMFT, Toulouse); Dynamics of free surface oscillations and wave propagation in a large wave canal (HYDRALAB, Barcelona), partially covered with sand, with measurements of both open water and groundwater levels, and of sand topography (erosion / deposition). For theoretical studies, we have developed linearized analytical solutions. Here is a sample problem that was treated analytically in this work: The linearized equation of Dupuit-Boussinesq (DB) for transient free surface flow, assuming horizontal flow and instantaneous wetting/drainage of the unsaturated zone: forced oscillations, wave transmission and dissipation through a rectangular sandbox. We also developed a weakly nonlinear solution of the Dupuit-Boussinesq equation to study the sudden imbibition (temporal monitoring of the wetting front). We have studied the different types of transient flow problems related to the experiments cited above by numerical simulation. In particular, we have simulated unsaturated or partially saturated transient flows in vertical cross-section, using a computer code (BIGFLOW 3D) which solves a generalized version of Richards’ equation. Thus, using the Richards / BIGFLOW 3D model, we have studied numerically the experiment of unsaturated imbibition in a dry sand (IMFT sandbox), and then, with the same model, we have also studied the partially saturated wave propagation experiment in the large Barcelona wave canal (HYDRALAB laboratory), focusing on the sloping sandy beach, with coupling between the micro-porous zone (sand) and the “macro-porous” zone (open water). To interpret the results of the latter experiment and compare them to simulations, we use several methods of signal analyzis and signal processing, such as: Fourier analysis, discrete multi-resolution wavelets (Daubechies), auto and cross-correlation functions. These methods are combined with pre-filtering methods to estimate trends and residuals (moving averages; discrete wavelet analyses). This signal analyzis has allowed us to interpret and quantify water propagation phenomena through a sandy beach. To sum up, different modeling approaches, combined with model calibration procedures, were applied to transient nonlinear coupled flow problems. These approaches have allowed us to reproduce globally the water content distributions and water level propagation in the different configurations studied in this work.

The purpose of this thesis was to study the efforts of ten Utah artists who played significant roles in formulating early Utah art history.

This thesis is the first full-length study of the English clergyman and historian William Cave (1637-1713). As one of a number of Restoration divines invested in exploring the lives and writings of the early Christians, Cave has nonetheless won only meagre interest from early-modernists in the past decade. Among his contemporaries and well into the nineteenth century Cave’s vernacular biographies of the Apostles and Church Fathers were widely read, but it was with the two volumes of his Scriptorum Ecclesiasticorum Historia Literaria (1688 and 1698), his life’s work, that he made his most important and lasting contribution to scholarship. The first aim of the thesis is therefore to build on a recent quickening of research into the innovative early-modern genre of historia literaria by exploring how, why, and with what help, in the context of late seventeenth-century European intellectual culture, Cave decided to write a work of literary history. To do so it makes extensive use of the handwritten drafts, annotations, notebooks, and letters that he left behind, giving a comprehensive account of his reading and scholarly practices from his student-days in 1650s Cambridge and then as a young clergyman in the 1660s to his final, unsuccessful attempts to publish a revised edition of his book at the end of his life. Cave’s motives, it finds, were multiple, complex, and sometimes conflicting: they developed in response to the immediate practical concerns of the post-Restoration Church of England even as they reflected some of the deeper-lying tensions of late humanist scholarship. The second reason for writing a thesis about Cave is that it makes it possible to reconsider an influential historiographical narrative about the origins of the ‘modern’ disciplinary category of literature. Since the 1970s the consensus among scholars has been that the nineteenth-century definition of literature as imaginative fictions in verse and prose – in other words literature as it is now taught in schools and universities – more or less completely replaced the early-modern notion of literature, literae, as learned books of all kinds. This view is challenged in the final section of this thesis, which traces the influence of Cave’s work on some of the canonical authors of the English literary tradition, including Johnson and Coleridge. Coleridge’s example, in particular, helps us to see why Cave and scholars like him were excluded lastingly from genealogies of English studies in the twentieth century, despite having given the discipline many of its characteristic concerns and aversions.

The aim of this thesis is to arrive at a characterisation of twentieth century poetry and science by means of a detailed study of the work of four poets who engaged extensively with science and whose writing lives spanned the greater part of the period. The study of science in the work of the four chosen poets, Hugh MacDiarmid (1892 – 1978), Judith Wright (1915 – 2000), Edwin Morgan (1920 – 2010), and Miroslav Holub (1923 – 1998), is preceded by a literature survey and an initial theoretical chapter. This initial part of the thesis outlines the interdisciplinary history of the academic subject of poetry and science, addressing, amongst other things, the challenges presented by the episodes known as the ‘two cultures' and the ‘science wars'. Seeking to offer a perspective on poetry and science more aligned to scientific materialism than is typical in the interdiscipline, a systemic challenge to Thomas Kuhn's The Structure of Scientific Revolutions (1962) is put forward in the first chapter. Additionally, the founding work of poetry and science, I. A. Richards's Science and Poetry (1926), is assessed both in the context in which it was written, and from a contemporary viewpoint; and, as one way to understand science in poetry, a theory of the creative misreading of science is developed, loosely based on Harold Bloom's The Anxiety of Influence (1973). The detailed study of science in poetry commences in Chapter II with Hugh MacDiarmid's late work in English, dating from his period on the Shetland Island of Whalsay (1933 – 1941). The thesis in this chapter is that this work can be seen as a radical integration of poetry and science; this concept is considered in a variety of ways including through a computational model, originally suggested by Robert Crawford. The Australian poet Judith Wright, the subject of Chapter III, is less well known to poetry and science, but a detailed engagement with physics can be identified, including her use of four-dimensional imagery, which has considerable support from background evidence. Biology in her poetry is also studied in the light of recent work by John Holmes. In Chapter IV, science in the poetry of Edwin Morgan is discussed in terms of its origin and development, from the perspective of the mythologised science in his science fiction poetry, and from the ‘hard' technological perspective of his computer poems. Morgan's work is cast in relief by readings which are against the grain of some but not all of his published comments. The thesis rounds on its theme of materialism with the fifth and final chapter which studies the work of Miroslav Holub, a poet and practising scientist in communist-era Prague. Holub's work, it is argued, represents a rare and important literary expression of scientific materialism. The focus on materialism in the thesis is not mechanistic, nor exclusive of the domain of the imagination; instead it frames the contrast between the original science and the transformed poetic version. The thesis is drawn together in a short conclusion.

Does the individual really matter in the post-modern world, brimming with countless signs and signifiers? My main objective in this writing is to demonstrate how this happens in Verhoeven's films, exploring his central themes and subtext and doing what science fiction does: hold a mirror up to the contemporary world and critique it, asking whether our species' current trajectory is beneficial or hazardous.; Dutch director Paul Verhoeven is a polarizing figure. Although many of his American made films have received considerable praise and financial success, he has been lambasted on countless occasions for his gratuitous use of sex, violence, and contentious symbolism--1995s Showgirls was overwhelmingly dubbed the worst film of all time and 1997s Starship Troopers earned him a reputation as a fascist. Regardless of the controversy surrounding him, his science fiction films are a move beyond the conventions of the big blockbuster science fiction films of the 1980s (E.T. and the Star Wars trilogy are prime examples), revealing a deeper exploration of both sociopolitical issues and the human condition. Much like the novels of Philip K. Dick (and Verhoeven's 1990 film Total Recall--an adaptation of a Dick short story), Verhoeven's science fiction work explores worlds where paranoia is a constant and determining whether an individual maintains any liberty is regularly questionable. In this thesis I am basically exploring issues regarding power. Although I barely bring up the term power in it, I feel it is central. Power is an ambiguous term; are we discussing physical power, state power, objective power, subjective power, or any of the other possible manifestations of the word? The original Anglo-French version of power means "to be able," asking whether it is possible for one to do something. In relation to Verhoeven's science fiction work each demonstrates the limitations placed upon an individual's autonomy, asking are the protagonists capable of independent agency or rather just environmental constructs reflecting the myriad influences surrounding them.
