The petroleum engineering literature clearly shows that large proppant volumes and concentrations are required to effectively stimulate low-permeability gas sands. To pump large proppant concentrations, one must use a viscous fluid. However, many operators believe that low-viscosity, low-proppant concentration fracture stimulation treatments known as ??waterfracs?? produce comparable stimulation results in low-permeability gas sands and are preferred because they are less expensive than gelled fracture treatments. This study evaluates fracture stimulation technology in tight gas sands by using case histories found in the petroleum engineering literature and by using a comparison of the performance of wells stimulated with different treatment sizes in the Cotton Valley sands of the East Texas basin. This study shows that large proppant volumes and viscous fluids are necessary to optimally stimulate tight gas sand reservoirs. When large proppant volumes and viscous fluids are not successful in stimulating tight sands, it is typically because the fracture fluids have not been optimal for the reservoir conditions. This study shows that waterfracs do produce comparable results to conventional large treatments in the Cotton Valley sands of the East Texas basin, but we believe it is because the conventional treatments have not been optimized. This is most likely because the fluids used in conventional treatments are not appropriate or have not been used appropriately for Cotton Valley conditions.

Les Journées Cinématographiques de Carthage (JCC) est un festival arabo-africain du cinéma créé en 1966, le plus vieux du continent africain et asiatique. Ces dernières décennies, il a connu de nombreux dysfonctionnements au niveau de l'organisation et des choix esthétiques des films sélectionnés pour la compétition, réservée exclusivement aux films arabes et africains. Mais, d'autres sections parallèles projettent hors compétition des films venant du monde entier. Dans cette thèse nous nous basons sur des entretiens que nous avons réalisés avec différents protagonistes, liés directement ou indirectement à la réalisation de ce festival depuis sa création jusqu'à ce jour. A partir de ces documents nous avons étudié l'organisation et la gestion du festival, et considéré l'esthétique qui se dégage du choix des films, étant donné qu'ils ont une portée militante, autour de thèmes évoqués qui relèvent de la dénonciation sociale politique et culturelle. Cette recherche est une tentative d'offrir un travail universitaire et un nouvel outil pour approcher le cinéma arabe et africain grâce au festival de Carthage, jusqu'ici peu étudié. / The JCC (« Carthagian days of cinematography ») is an Arab-African film festival established in 1966, the oldest on the continent. Over the last decade, the festival has seen number of challenges on the organizational level as well as in its film selection; the competition remained exclusively reserved to African and Asian films. In parallel sections not being part of the competition films were shown from around the world. The present thesis is based on interview conducted with a wide range of protagonists directly or indirectly responsible for managing the festival ever since its creation. Based on these primary sources, the organization and the management of the festival were analyzed as well as the aesthetic concept that could be derived through the selection of films especially through from their political or cultural content. This research is an academic accomplishment and an attempt to offer a new working tool to ease research on Arabic and African cinematography through the festival of Carthage that until now remains a festival hardly studied.

Thomas Ford was the governor of Illinois at the time of Joseph and Hyrum Smiths’ martyrdoms in Carthage Jail in 1844. Before his tenure as governor, Ford’s professional life included service as an attorney and judge throughout Illinois. His background in the legal field gave him a unique perspective which may have influenced his career as governor of Illinois from 1842-1846. Although Governor Ford is relatively well-known for his association with The Church of Jesus Christ of Latter-day Saints and its history, his background and the bearing it had on the martyrdom of the Smiths has received relatively little attention from scholars. In this thesis I contend that Governor Ford’s choices in Carthage, Illinois can be traced in some ways to his legal background. I also examine his earliest interactions with Joseph Smith in 1842-1843, and how those interactions may have also been influenced by Ford’s legalistic viewpoints. I suggest it is possible Ford’s legal background more than his political experience may have had the most bearing on those interactions. Chapter one summarizes some of the financial, political, and mobocratic difficulties citizens in Illinois dealt with in the late 1830s and early 1840s. This context shows that even before Ford’s election in 1842, Illinois had severe challenges that affected the Saints and their neighbors. Chapter two explores some of the legal cases Ford heard while serving on the Illinois bench and bar. This chapter investigates the unique balance Ford attempted to maintain between law and justice, while also suggesting Ford may have occasionally strayed from consistently following the law. In chapter three, Ford’s transition into a political figure in Illinois history, as well as his extensive interactions with Smith are analyzed. Throughout these interactions, Ford seemed to frequently rely on his background in law to help him make decisions about Smith. This analysis is continued in chapter four when Ford chose to intervene in Hancock County after the Nauvoo Expositor printing press was destroyed. This chapter systematically relates Ford’s previous legal cases to the specific choices he made in Carthage. As a conclusion, chapter five serves to summarize these findings, and also opens further opportunities for research that demonstrate how Ford’s interactions with the Saints in Illinois may have continued to be affected by his past. This thesis provides research suggesting Ford’s choices surrounding the Smiths in Hancock County can be traced to his past and should not necessarily be considered isolated events in 1844. Furthermore, it adds to our understanding of church history by giving another paradigm in which to examine the martyrdom of Joseph Smith in Carthage Jail.

This dissertation deals with a holistic and multidisciplinary approach to the socio-economic relations between the Ancient Near East and East Africa during the Old Testament period. In my opinion this multidisciplinary approach by using inter alia Biblical Archaeology, History and Economics has the potential to offer various comprehensive opportunities for the analysis and discussion of such socio-economic relationships. For example, the relationship between the United Monarchy of Israel and Phoenicia involves the geopolitical, economic and other situations. In the last chapter attempts are made to integrate all the relevant dimensions in a wellfounded conclusion. / Biblical and Ancient Studies / M.A. (Biblical Archaeology)

The Phoenicians were known as artisans, merchants, and seafarers by the 10th century B.C.E. They exchanged raw and finished goods with people in many cultural spheres of the ancient world and accumulated wealth in the process. A major factor that aided their success was the establishment of colonies along the Mediterranean and eastern Atlantic coasts. These colonies, established by the eighth century B.C.E., supplied valuable raw materials to the major Phoenician cities in the Levant, while also providing additional markets abroad. Excavations at a myriad of these colonial sites have recovered materials that can be used to identify connections between the colonies, the Levantine cities, and non-Phoenician cultures across the ancient world. By establishing these connections the system of maritime exchange can be better understood and modeled as the Phoenician Trade Network. This network involved both direct and indirect exchange of raw and finished products, people, as well as political and cultural ideas. The colonies were involved in various activities including ceramics production, metallurgy, trade, and agriculture. Native peoples they interacted with provided valuable goods, especially metals, which were sent east to supply the Near Eastern Markets. The Phoenician Trade Network was a system of interconnected, moderately independent population centers which all participated in the advancement of Phoenician mercantilism and wealth. Ultimately, the network collapsed in the sixth century B.C.E. allowing other powers such as the Romans, Carthaginians, and Greeks to replace them as the dominant merchants of the Mediterranean.

This dissertation enhances Marlovian studies by advancing ongoing scholarly efforts to demystify Marlowe’s stereotypical image as an outsider of his era. Specifically, it aims to challenge the prevailing perception of Christopher Marlowe as a subversive maverick, often delineated in contradistinction to William Shakespeare, England’s so-called national poet. Situating Marlowe in the context of nation-building in early modern England, this dissertation explores how Marlowe participated through his writing in the construction of English national identity. Through reading Marlowe’s five plays, Dido Queen of Carthage, Tamburlaine the Great Part One, Tamburlaine the Great Part Two, Edward II, and The Jew of Malta, my dissertation reveals that Marlowe’s ideal England is a political entity of complete sovereignty, a new empire of unprecedented achievement, and an imagined community ruled by its monarch and governors with good governance. With its emphasis on the inseparable fusion of nation and empire and the inevitable incorporation of outsiders, such English nationhood, I suggest, is an eighth form of nationhood in addition to the seven others proposed by Richard Helgerson. It is neither Patrick Cheney’s counter-nationhood nor completely Helgerson’s nationhood under royal absolutism. Since the monarch and patriotism are at its centre, Marlowe’s ideal English nationhood does not differ greatly from depictions offered by other contemporary writers. I argue that Marlowe shares more commonality with other authors of his era than has previously been understood, at least in terms of writing English nationhood. I propose that we should explore such commonality, rather than fetishizing Marlowe’s peculiarity, to gain a more nuanced, fuller image of Marlowe, who has long been obscured by his arguably more renowned contemporaries. / Dissertation / Doctor of Philosophy (PhD) / This dissertation reexamines Christopher Marlowe’s stereotypical image in current scholarship as an outsider of his era by looking at how Marlowe writes about England in the context of early modern nation-building. Focusing on Marlowe’s five plays, Dido Queen of Carthage, Tamburlaine the Great Part One, Tamburlaine the Great Part Two, Edward II, and The Jew of Malta, my readings reveal that what Marlowe envisions through his writing is an English nation marked by complete autonomy, remarkable achievement, and good governance. At the heart of this nationhood lies the patriotism similarly expressed by other Elizabethan writers in their literary fashioning of English nationhood. I argue that Marlowe, in this regard, shares more commonality with his contemporaries than has previously been understood. Exploring this commonality allows us to revalue the historical position of Marlowe, who has long been obscured by arguably more renowned writers of his day.

Summaries in Afrikaans and English / Text in Afrikaans / Die tema van hierdie studie toon die kerkbegrip van Cyprianus aan as 'n spanning tussen die kerk as instituut en die kerk van die Gees. Hoofstuk een skets die invloed van Tertullianus as leermeester op Cyprianus. Tertullianus se kerkbegrip getuig self van spanning wat die produk is van 'n verandering van lidmaatskap vanaf die Katolieke kerk na die Montaniste. Tertullianus se kerkbegrip word vanuit twee perspektiewe belig. Eerstens vanuit 'n Katolieke, met 'n fokus op die fundering van die ware kerk en die mag van die kerk om sondes te kan vergewe. Tweedens vanuit 'n Montanistiese, wat die def iniering van die ware kerk en die mag van die kerk om sondes te kan vergewe eksklusief geestelik begrond. Hoofstuk twee skets die milieu waarbinne Cyprianus gearbei het. Dit sluit in 'n biografie van Cyprianus en die Afrika-religie en bevolking. Tweedens word die Europese invloed op Cyprianus se kerkbegrip aangedui. Die invloed van die Romeinse staatkundige model kan duidelik waargeneem word. Die grootste invloed was egter die Roomse kerklike model, weens die dinamika van die Roomse kerk. Hoofstuk drie skets die ekklesiologie van Cyprianus. Die spanning tussen die kerk as 'n instituut en die kerk van die Gees word aangedui deur 'n bespreking van die episkopaat; die betekenis van die biskop; Cyprianus se gesagsbegrip en sy perspektief op die primaat. Cyprianus se Bybelse verbintenis, sowel as die twee historiese lyne, naamlik die Pauliniese lyn en die Petruslyn, plaas sy uitspraak salus extra ecclesiam non est in perspektief. Cyprianus se kerkbegrip is primer 'n ekklesiologie van die Gees. In sy strewe na die eenheid van die kerk vind hy die kerk as instituut egter onontbeerlik. Spanning onstaan in sy poging om 'n sintese tussen die twee te vorm. / The theme of this study reveals the tension to be found between the church as institution and the church of the Spirit, in the ecclesiology of Cyprian. Chapter one shows the influence which Tertullian, as tutor, exerted on Cyprian. The ecclesiology of Tertullian also reveals the tension which is produced by the change of membership from Catholicism to Montanism. Tertullian's ecclesiology is highlighted from two different perspectives. Firstly from a Catholic view, with the focus on the fundamentals of the true church, and the authority and power of the church to forgive sins. Secondly, a Montanist view is proposed, which defines the true church, and the power it yields in forgiving sins, as being exclusively spiritual in nature. Chapter two describes the environment in which Cyprian worked. This includes a biography of Cyprian, as well as the African religion and people. Secondly the European influence is shown on Cyprian's ecclesiology. The influence exerted by the Roman state model is also clearly seen. The major influence though, was exercised by the Roman church model, on account of the dynamics of the Roman church. Chapter three describes Cyprian's ecclesiology. The tension between the church as institute and the church of the Spirit is revealed in a discussion on the episcopacy; the significance of the bishop; Cyprian's view on authority and his perspective on the primacy. Cyprian's biblical connection, as well as the two historical lines, namely the Pauline and Petrine lines, put his salus extra ecclesiam non est pronouncement in perspective. ecclesiology the unity of Cyprian's view is primarily that of a of the Spirit. In his striving towards the church though, he finds the church as institute to be indispensable. Tension develops in his endeavor to form a synthesis between the two. / Christian Spirituality, Church History and Missiology / D. Th.
