La notion d'un esprit étranger et invisible qui prend possession d'un corps est, croit-on, sémitique. Les peuples proche-orientaux et juifs avaient développé des rituels et des pratiques spécifiques pour s'en débarasser. Les Grecs, pour leur part, avaient parfois à composer avec différentes entités, des daimones, des morts ou des apparitions et parfois des divinités dont les actions pouvaient s'avérer très nuisibles, si ce n'est nettement invasives. Toutefois, la communis opinio maintient que les concepts de la possession et de l'exorcisme ne furent chez eux, que tardivement introduits, et ce, sous l'influence des sémitiques. Pourtant, la littérature et les sources épigraphiques, papyrologiques et archéologiques semblent démontrer que les Grecs avaient déjà, dès l'époque classique, dans leur propre culture et religion, les éléments caractéristiques de la possession et de l'exorcisme. Une analyse approfondie de textes d'auteurs anciens, de formulaires de magie,dont les très connus Papyri Grecs Magiques et de diverses amulettes, apporte des arguments décisifs en ce sens. / The notion of an alien and invisible spirit who takes possession of a person is believed to be Semitic. The Near East and Jewish people had developed rituals and specific practices to get rid of them. The Greeks, meanwhile, had to deal with numbers of entities, daimones, dead or apparitions and sometimes with the gods themselves, whose actions could be very harmful, if not clearly invasive. Nevertheless, the communis opinio holds that the concepts of possession and exorcism where belatedly introduced, and this only under the influence of Semitics. However the literature and the epigraphic, archaeological and papyrological sources seems to show that the Greeks already had, from the classical period, in their own culture and religion, the characteristic elements of possession and exorcism. A detailed analysis of some ancient texts, of magical formularies, including the well-known Greek Magical Papyri, and of various amulets, provides decisive arguments in this direction.

L'utilisation intensive des produits phytosanitaires, en particulier les insecticides, provoque des effets indésirables sur les organismes vivants et leur environnement. Mon travail de thèse a consisté à évaluer l'effet de deux insecticides chez un insecte modèle la drosophile. Une première étude concernait l'effet d'un néonicotinoïde, l'imidaclopride. Nous avons pu montrer que l'exposition chronique à des doses sublétales de cet insecticide perturbe la fonction de reproduction chez la drosophile. D'autre part, une exposition aiguë à l'imidaclopride a mis en évidence une résistance chez les femelles d'une souche de drosophile dite ''des champs''. Deux mécanismes différents ont été mis en évidence dans la résistance à l'imidaclopride de cette souche. Le premier concerne la sous expression d'une sous-unité (D1) du récepteur nicotinique à l'acétylcholine, cible de l'imidaclopride. Le deuxième concerne l'implication des glutathion S-transférases, enzymes de détoxification, dans le métabolisme de l'imidaclopride. Ces études montrent que les insecticides peuvent avoir en plus des effets sur les insectes ravageurs, des effets néfastes sur des organismes non cibles. La deuxième étude avait pour but de modéliser chez la drosophile, l'impact d'un organochloré, la dieldrine, potentiellement impliquée dans la maladie de Parkinson chez l'homme. L'exposition à cet insecticide conduit à une dégénérescence des neurones dopaminergiques ainsi qu'une perturbation de la structure de régions particulières du cerveau. Nous avons également montré des altérations du métabolisme et l'implication de processus épigénétiques dans la neurodégénérescence induite par la dieldrine. Au cours de ce travail, nous avons pu montrer l'intérêt de nouvelles méthodes comme l'Imagerie par Résonance Magnétique (IRM) ou le High Resolution Magic Angle Spinning (HRMAS) dans ce type d'étude.

This thesis is an intensive, multi-layered analysis of an unpublished, English language, handwritten, mid-20th century manuscript. Originally undated, untitled and unsigned, it has now been positively identified as “Text A”, a Wiccan proto-Book of Shadows compiled by Gerald Brosseau Gardner (1884-1964) in the last half of the 1940’s. Different methodologies were applied to the document: transcription using Leiden conventions, handwriting analysis to identify the author, archival research to uncover photographs of the manuscript in use, historical and bibliographical research to situate the manuscript and its author, and finally, an in-depth and exhaustive source analysis to uncover literary and documentary influences on the text. Subsequently, the manuscript was identified as handwritten by Gerald Gardner, from 1940 to 1949, and contains almost no original material other than a handful of pages for a speech or oral presentation. The rest of the document is comprised of extracts from published sources available to Gardner. These include books on Free Masonry, Templars, British Folklore, Kabbalah, Magic – ancient and ceremonial, and books by Aleister Crowley. The document also includes ritual passages and ceremonies, most of which also appear in Gardner’s published novel, High Magic’s Aid. Two theme-lines, “Magic – ancient and ceremonial” and “the writings of Aleiser Crowley”, comprising almost 40% of the total page count, were chosen for thorough analysis. Based on the information revealed by the various methodologies applied to this document, one can assert that Gardner’s claims to have been initiated into an ancient indigenous tradition, Wicca, and to be making available its long secret rituals are not supported by this document.

Ultra-cold atoms in optical lattices provide a versatile and robust platform to study fundamental condensed-matter physics problems and have applications in quantum optics as well as quantum information processing. For many of these applications, Rydberg atoms (atoms excited to large principal quantum numbers) are ideal due to its long coherence times and strong interactions. However, one of the pre-requisite for such applications is identical confinement of ground state atoms with Rydberg atoms. This is challenging for conventionally used alkali atoms. In this thesis, I discuss the potential of using alkaline-earth Rydberg atoms for many-body physics by implementing simultaneous trapping for the relevant internal states. In particular, I consider a scheme for generating multi-particle entanglement and explore charge transport in a one dimensional atomic lattice.

This thesis is an examination of the belief and practice of popular magic, specifically related to charmers, in the presbyteries of Haddington and Stirling between the years 1603 and 1688. It is the first study of either locality which concentrates on identifying the difference between charmers and witches, and considers the practice of the former in the broader context of seventeenth-century attitudes towards health and disease of both orthodox medical practitioners and the wider population. The thesis examines charmers and their healing practice in reference to theories of power, popular and elite culture, the church and gender, and reveals new information about seventeenth-century society. The principles and practice of charmers are then compared to orthodox medicine and popular magic, and the recorded healing treatments and rituals have been examined and analysed in close detail. A comparative analysis has been made of the two localities which assesses and contrasts patterns of witchcraft and charming accusation on a parish level. By using evidence contained in kirk records, supplemented by secular court material, it has been shown that all levels of society identified differences between the practice and intent of charmers and witches. Accusation and prosecution of witches was influenced more by local elites, and by elite demonological theories, than accusations of charming. Importantly, the devil was not a feature of charming accusations. Due to the overt nature of charming, differences in its perception and acceptability were highlighted by the less severe penalties which were ordered by the kirk. The dilemma for the church and society was that the church had, to an extent, surrendered its practical healing role with the abandonment of pre-Reformation ritual. The emphasis on personal piety and prayer for the relief of mental and physical suffering did not appear to offer sufficient comfort for the rest of society.

Early modern representations of witchcraft have been the subject of considerable recent scholarship; however, three significant aspects of the corpus have not received sufficient attention and are treated independently here for the first time. This dissertation will examine how witchcraft imagery invited discourse concerning the reality of magic and witchcraft and suggested connections to contemporary issues through the themes of the witch’s violent autonomy, bestial passions, and unnatural interactions with the demonic and the dead. These three themes address specific features of the multifaceted identity of the witch and participate in a larger discussion that questioned the nature of humanity. Analysis of each issue reveals a complex, ambiguous, and often radically open treatment of the subject that necessitates a revision of how witchcraft imagery from this period is understood. Each understudied aspect of witchcraft imagery is explored through a series of case studies that have not appeared together until now. Previously unexamined artworks with inventive content are introduced and canonical pictures are examined from new perspectives. These images were created in the principal artistic centers, the Italian city-states, the German provinces, and the Low Countries, during the sixteenth and seventeenth centuries when the controversy over witchcraft was at its peak. Although they are few in number, these highly innovative images are the most effective and illuminating means by which to access these themes. These works of art provide valuable insights into important issues that troubled early modern society. Chapter 1 reveals how witchcraft imagery produced in the Low Countries is concerned with the witch’s violent rejection of the social bonds and practices upon which the community depends for survival. Chapter 2 examines how the figure of the witch was used to explore concerns about the delineation and transgression of the human-animal boundary. Chapter 3 exposes an interest in the physical possibility of witchcraft; artists questioned the ability of witches and demons to manipulate the material world. Issues include the witches’ capacity to reanimate dead bodies and create monstrous creatures. Together these images demonstrate active and meaningful engagement with the theories, beliefs, and practices associated with witchcraft.

The overall objective of this study was to develop and characterise new normoxic polymer gel formulations for evaluation of complex 3-D treatment volumes for application in radiotherapy dosimetry. Throughout this thesis, the essential characteristics of normoxic polymer gels have been extensively investigated. Studies were performed on the chemical components of the MAGIC gel and an improved formulation was proposed. Various anti-oxidants were studied and different versions of the MAGIC gel with fewer chemicals were developed and named MAGAS and MAGAT gel dosimeters. The ascorbic acid anti-oxidant was found to have a slow oxygen scavenging rate and therefore a delay period between manufacture and irradiation of the MAGAS gel was necessary before the gel became radiation sensitive. Vacuum pumping on the MAGAS gel solution to remove dissolved oxygen was shown to initially increase the R2-dose response and sensitivity of the dosimeter, reducing the time between manufacture and irradiation. Studies of the MAGAS gel for measurement of depth dose showed that MAGAS gel has potential as a clinical radiotherapy dosimetry tool. The radiological properties of MAGIC, MAGAS and MAGAT gels were investigated. Due to their high gelatine and monomer concentration, differences with water were observed for the cross-section ratios for attenuation, energy absorption and collision stopping power coefficient ratios through the therapeutic energy range. It was determined that when using and developing normoxic polymer gels the most important consideration for radiological water equivalence are the mass and relative electron densities. A preliminary study was performed with the hypoxic PAG gel dosimeter combined with tetrakis (hydroxymethyl) phosphonium chloride anti-oxidant to form a normoxic PAG gel dosimeter named PAGAT gel. It was found PAGAT gel compared favourably with previous studies of the hypoxic PAG gel. An extensive study was subsequently undertaken in which PAGAT gel was investigated for a number of essential characteristics. The PAGAT gel formulation showed potential as a normoxic polymer gel for clinical radiotherapy dosimetry, which has a significantly reduced manufacturing time and procedure compared with the hypoxic PAG gel dosimeter. The radiological attenuation properties of the PAGAT and MAGAT gels were investigated as a feasibility study for using x-ray computerised tomography (CT) as an evaluation technique of normoxic polymer gels. CT was shown to have potential as an evaluation tool for measuring the dose response of normoxic polymer gel dosimeters. An investigation was performed on the CT diagnostic dose response of normoxic polymer gels. Normoxic polymer gels were found to have potential for use as a specialised tool in measuring computerised tomography dose index (CTDI) for acceptance testing and quality assurance of CT scanners in diagnostic radiology. These findings provide a significant contribution toward the development and successful implementation of normoxic polymer gel dosimetry to clinical radiotherapy.

This study focuses on trends in contemporary Australian playwrighting, discussing recent investigations into the playwrighting process. The study analyses the current state of this country’s playwrighting industry, with a particular focus on programming trends since 1998. It seeks to explore the implications of this current theatrical climate, in particular the types of work most commonly being favoured for production. It argues that Australian plays are under-represented (compared to non-Australian plays) on ‘mainstream’ stages and that audiences might benefit from more challenging modes of writing than the popular three-act realist play models. The thesis argues that ‘New Lyricism’ might fill this position of offering an innovative Australian playwrighting mode. New Lyricism is characterised by a set of common aesthetics, including a non-linear narrative structure, a poetic use of language and magic realism. Several Australian playwrights who have adopted this mode of writing are identified and their works examined. The author’s play Floodlands is presented as a case study and the author’s creative process is examined in light of the published critical discussions about experimental playwriting work.
