The exhibition presents the artist's experimentation and exploration into a variety of different materials, namely wood, steel, paper, linen thread, and milk paint. Topics discussed are the influences, techniques, and methods directly relating to the work. Included are preliminary and detail images as well as a complete catalogue of the thesis exhibit.

This thesis compares the dancing of the Shakers (The United Society of Believers in Christ's Second Appearance) and the Mormons (The Church of Jesus Christ of Latter-day Saints or LDS Church) during the nineteenth century, as it was influenced by their doctrinal beliefs about the human body. Specifically, it examines how the role of the physical body in achieving mortal happiness and immortal salvation was viewed by each group and how these beliefs were reflected in their dancing. It describes the different forms of dancing performed by each religious group and how dance functioned as worship and recreation for the members of each religion during the nineteenth century.Research for this study was taken from primary and secondary sources, including a large number of Shaker and Mormon journals, diaries, and autobiographies. Major doctrinal works from each religion were also consulted to compile a summary of doctrinal beliefs about the physical body for each religion.This study found that the dancing of the Shakers reflected doctrinal beliefs of the need to be freed from the corrupt human body. In contrast, the dancing of the Mormons exhibited the Latter-day Saint belief in celebrating the body. The doctrines of each religion about the role of the body in attaining mortal joy and immortal salvation were easily recognizable in the dances that the two groups performed. Although beliefs about the body cannot be considered in isolation of other motivational factors, they can be used as a means of studying how and why particular religious or cultural groups dance. This method of evaluating dance, as a function of beliefs or ideologies about the human body, is given as a possible method for studying other cultural or societal groups who dance and whose beliefs about the body may be reliably gathered.

In 1807 the United Society of Believers in Christ’s Second Appearing (Shakers)established a society near the Gasper River in Logan County, Kentucky. The society was soon named South Union, and it lasted until 1922, the longest-lasting Shaker community west of the Appalachians. Most of the first Shaker converts in Logan County had only a few years beforehand participated in a series of evangelical Presbyterian camp meetings known collectively as the Kentucky Revival, the Revival of 1800, or the Great Revival.Though Presbyterian revivalism and Shakerism shared certain characteristics (particularl millennialism and enthusiastic forms of worship), there were many differences between them as well; Shakerism was not necessarily a logical continuation of the Great Revival. So why did so many Scots-Irish Presbyterians in south-central Kentucky convert to Shakerism? How did conversion make sense to them? And how was Shaker conversion understood by those who did not convert? Through a close reading of primary sources, this thesis attempts to answer these questions. Shaker conversion is better understood as an interaction within a community rather than as a transaction between an individual and God. The decade or so preceding the establishment of South Union—the disestablishment of state churches, the mass migration to the trans-Appalachian west, the burgeoning market economy—was, for many Scots-Irish Presbyterians, a period of social disorder. This was especially true in south-central Kentucky, where the local Presbyterian establishment was riven by schism. The Great Revival was a brief but ultimately disappointing creation of an alternate community, a way of escape from the surrounding chaos. Shakerism offered the apotheosis of that alternate community. South Union was a camp meeting that never ended. However, the denizens of south-central Kentucky who did not convert to Shakerism were quite hostile to the new sect. They understood conversion as a form of betrayal, a renunciation of a community which they still identified with. This understanding became especially clear during a divorce case involving William and Sally Boler, in which William Boler’s rights as a man and a citizen became circumspect because of his conversion to Shakerism. Since the mid-nineteenth century, Shaker conversion has become less threatening to the outside world. Indeed, the popular imagination has co-opted South Union as quintessentially American. By reclaiming the Shakers from the margins of society, popular memory has effectively erased conversion from the Shaker story. After all, Shaker conversion was never as much about belief or even practice as it was about a distinct and separate community.

The United Society of Believers in Christ’s Second Appearing, commonly called Shakers, are a most unique communistic group in American history. Their society had an economic as well as a religious base. Because of this entwining relationship, the Shakers outlived all other communistic societies in the United States. From the beginning the Shakers placed great emphasis on the economic aspects of their communal society and this emphasis played a paramount role in many of their major decisions. In effect their theory was “Mine is thine and thine is mine.” Taking their beliefs from this statement, together with the preaching of Mother Ann Lee, founder of the society, the Shakers evolved as long as they had sufficient membership to do the needed work. Indeed, industry was one of the first lessons taught to the Shaker. One of the outstanding Shaker communities was located at South Union, in Logan County, Kentucky. This colony evolved from the Second Great Awakening which had its early beginnings in Kentucky. The notable economic progress made by the South Union Shakers prior to the Civil War will be the topic of this paper. The author will inquire into several questions that are necessary for an understanding of the development and maturation of the South Union Shaker colony. The agricultural crops and livestock development will be investigated, the manufacturing and selling will be examined, and the improvements made on the Shaker property will be considered. An understanding of the Shakers’ economic base is important. By this economic stability the Shakers were able to outlive the other communal groups in America. There are several hypotheses of this study. The Shakers produced many varieties of fruits and vegetables in an area in which there was little variation in agricultural products. Livestock played an important part in the economy of the South Union Shakers, and they made a sincere effort to improve the blood line of their stock. The Shakers produced many goods and services that were used by non-members, and the newest methods in marketing, advertising, and selling were employed. They made extensive improvements on their land and buildings. This paper will begin on a very broad basis with a general history of the development of the Shaker Society and its general spiritual beliefs. From this point the writer will devote a chapter to the effects on economics resulting from their spiritual and temporal beliefs. Having established a basic understanding of the place of economics in a Shaker community, the writer will investigate the case in point – South Union. There will follow a discussion of the South Union colony in three basic areas: crops and livestock, manufactured goods and selling, and internal improvements. The author will then make his conclusions. The study will be confined to the period between the founding of the South Union colony in 1807 and the beginning of the Civil War in 1861. For the sake of clarity, it will be necessary on occasion to bring to the reader information from before and after this span of years.

This thesis explores ideas of everydayness, the mundane, and the repetitive emptiness of consumer culture. It looks at the malaise that plagues everyday life and examines several attempts throughout history to break from its grips which revolve around a search for a more ideal state. This research includes utopias of modernism, the transcendental, the communal living of Shakers and Early Christians, ascetic monks and The Desert Fathers. These ideas have shaped my studio practice as I construct installations based on worlds which allude to the eternal, the otherworldly, and the fragility of our physical world when compared to more eternal spiritual archetypes.

This thesis is a rhetorical analysis of utopian discourse about marriage in mid-nineteenth-century America. Although utopian communities are usually approached within the fields of history and sociology, a rhetorical analysis adds to the discussion by uncovering the discursive complexity of marriage beliefs within a rapidly changing culture. Discursive features of the Shaker, Oneida Community and Latter-day Saint texts are outlined and compared according to the following format:Chapter One examines the textures of conflict within the dominant culture's views of marriage and gender roles in nineteenth-century America, with a brief overview of reform efforts of the day. This chapter provides a wide context of marriage discourse in this era, which situates emergent utopian discourse of alternative marriage constructs.Chapter Two narrows the focus to utopian discourse, analyzing how utopian rhetoric responded to concerns of the dominant culture (outlined in Chapter One) and shaped their cultural identities. This chapter outlines several general features of utopian discourse about marriage and gender roles, with detailed analyses of the rhetoric of Shakers and the Oneida Community regarding thier alternatives to traditional marriage constructs.Chapter Three builds on the context of the first two chapters and further narrows the scope of analysis to Mormon Polygamy dsicourse. Public and private accounts are considered in a comparison of official church rhetoric with women's discourse about the principle. The last two chapters also show utopian departures from and similarities to mainstream discourse about marriage and gender roles.Although the three groups examined responded to mainstream concerns with some discursive similarities, rhetorical analysis shows that differences also exist, such as their rhetoric of gender identity and church authority. The Latter-day Saints stand out against the wider context of utopian discourse for their patriarchal model, their tenets of both continuous and personal revelation, and their enduring success as a religion.

FAPEMIG - Fundação de Amparo a Pesquisa do Estado de Minas Gerais / Petrobrás - Petróleo Brasileiro S.A / Os fluidos de perfuração são substâncias injetadas no poço cuja principal função é trazer à superfície os cascalhos de rocha produzidos durante a perfuração. A separação e a reutilização do fluido de perfuração são de suma importância para que se atenda às exigências da legislação ambiental em relação ao descarte de resíduos. Além disso, é imprescindível a recuperação do fluido utilizado por questões de redução de custos da etapa de perfuração. O objetivo do presente estudo foi desenvolver um modelo matemático para a separação entre cascalho e fluido de perfuração por peneiras vibratórias com base nos princípios da dinâmica newtoniana e da lei de conservação de massa. Para tanto a tela da peneira foi considerada um leito empacotado de espessura muito fina e com inclinação ascendente. Correlações para a queda de pressão foram analisadas e uma nova correlação foi proposta com base em metodologias indicadas na literatura. O comportamento do fluido foi avaliado para a variação nos seguintes parâmetros: viscosidade plástica, tensão limite de escoamento, coeficiente de escoamento, inclinação da tela e força-g. O modelo não se mostrou sensível a variações na tensão limite de escoamento do fluido. Os demais parâmetros mostraram significativa influência sobre o comprimento de tela molhada. Os resultados obtidos estão de acordo com o relatado pela literatura e mostram que o modelo desenvolvido é adequado para a descrição do processo de peneiramento vibratório. / Drilling fluids are substances injected into the well whose main function is to suspend drilled solids, remove them from the well bore and release them at the surface. Separation and reuse of drilling fluids is of great importance to fulfill the requirements of environmental legislation regarding waste disposal. In addition, it is essential to recover the drilling fluid in order to reduce costs of the drilling process. The objective of the present study was to develop a mathematical model based on the principles of Newtonian dynamics and the law of mass conservation for the process of removal of drilled cuttings from drilling fluid using vibrating screens. For this purpose, the sieve screen was considered to be a very thin packed bed and tilted upward. Pressure drop correlations were analyzed and a new correlation was proposed based on methodologies indicated in the literature. The behavior of the fluid was evaluated for the variation in the following parameters: plastic viscosity, yield stress, flow coefficient, tilt of the screen and g factor. The model was not sensitive to variations in the yield stress of the fluid while other parameters showed a significant influence on wet screen length. Obtained results are in agreement with the reported ones in the literature and show that the developed model is suitable for the description of the process of vibrating screening. / Dissertação (Mestrado)
