Interactions and Implications of a Collector Well with a River in an Unconfined Aquifer with Regional Background Flow

Dugat, William D., IV 14 January 2010 (has links)
Ranney radial collector wells consist of an array of horizontal lateral wells arranged radially around and connected to the base of a vertical well. They offer numerous advantages over traditional vertical wells with application in both the petroleum industry and hydrologic sciences. This study improved the understanding of the interaction of collector wells and the aquifers/reservoirs they tap by numerically modeling flux exchanges between a collector well and a river in an unconfined aquifer with regional background flow. Modeling demonstrated that flux along each horizontal lateral increased with distance from the vertical well stem following a third order polynomial function. Ultimately these models demonstrated that in the collector well/aquifer/river system, the pumping rate of the collector well was the dominant factor in controlling flux between the river and aquifer under various conditions. This study can be used to project the maximum allowable pumping rate without causing an initially gaining river to become a losing river.

A Mathematical Model of Horizontal Wells Productivity and Well Testing Analysis

Lu, Jing 07 September 1998 (has links)
This thesis presents new productivity and well testing formulae of horizontal wells. Taking a horizontal well as a uniform line source, this thesis finds velocity potential formula and the productivity formulae for a horizontal well in an ellipsoid of revolution drainage volume by solving analytically the involved three-dimensional partial differential equations. These formulae can account for the advantages of horizontal wells, and they are more accurate than other formulae which are based on two-dimensional hypotheses. This thesis also presents new well testing formulae of horizontal wells in a single porosity system and a double porosity system. Compared with the formulae published in the literature, our formulae, which do not use the sum of infinite series, are more reasonable and easy to be used in well testing analysis. / Master of Science

An Exploration of the Relationships Among Individual and Interpersonal Goal Pursuit and Hedonic and Eudaimonic Well-being

Procacci, Erin Nicole 30 September 2008 (has links)
Studies in the areas of goal pursuit and well-being suggest that the goals people work toward in their daily lives are important contributors of well-being. However, research to date has focused primarily on aspects of the individual in goal pursuit even though goals are not pursued in isolation. In fact, there is evidence that this emphasis on the individual, particularly salient in Western cultures, has negative consequences at both the individual and community levels. With regard to well-being, data have indicated that it is best represented as two dimensional, including hedonic and eudaimonic well-being. However, the research on personal goals has primarily focused on hedonic well-being of the individual. Overall, hedonic well-being appears to be more related to affective experience, whereas eudaimonic well-being appears to be more comprehensive and related to topics like purpose in life, self-acceptance, and positive relations with others. The theoretical framework of Virtue Ethics posits that social affiliations are essential for human beings to flourish and experience eudaimonia, and this study examines that premise. A two-step approach to structural equation modeling was used to contribute to the extant literature on goal pursuit and well-being by 1) exploring the individual and interpersonal dimensions of goal pursuit and their relationships to hedonic and eudaimonic well-being and 2) exploring the interpersonal dimensions of goal pursuit as a mediator of the relationship between individual dimensions of goal pursuit and eudaimonic well-being. The retained structural model from the two-step approach included Efficacy (an Individual Dimension of Goal Pursuit) and Generativity (an Interpersonal Dimension of Goal Pursuit). Results demonstrated that Efficacy and Generativity were both significantly related to Hedonic and Eudaimonic Well-being; however, Generativity was more strongly related to Eudaimonic than Hedonic Well-being. These findings were consistent with the premise of Virtue theory, that those engaged in goal pursuit with or on behalf of others are more likely to experience higher levels of eudaimonic well-being. Future research should include further exploration of the Interpersonal Dimensions of Goal Pursuit and well-being specifically by focusing on improving measurement for the Interpersonal Dimensions of Goal Pursuit, Hedonic, and Eudaimonic Well-being.

Culture and Subjective Well-Being: A Cross-Cultural Evaluation of Methods

Sanchez, Indira 01 January 2018 (has links)
The study of subjective well-being an interdisciplinary field that borrows from and contributes to disciplines such as psychology, economics, philosophy, and related fields due to the positive effects correlated with high subjective well-being. Cross cultural examinations of well-being help expand the knowledge base of subjective well-being, however, if current measures fail to take into account cultural variances in subjective well-being it undermines the validity of subjective well-being as a construct because western understandings of well-being are not as generalizable to other cultures as seems to be assumed by some measures. This essay provides an examination of popular measurements of subjective well-being and an analysis of the way they could interact with cultural differences in constructs related to subjective well-being.

Working towards 'a production of well-being' : an ethnography on craftsmanship among the Lulesámi in Norway

Gustafsson, Anna January 2015 (has links)
This thesis is an ethnographic study of craftsmanship among the Lulesámi in Northern Norway. The study, which is based on an apprentice-style methodology, focuses in particular on the role and significance of making and wearing the gáppte, a characteristic Sámi dress. While the gáppte is often employed to visually define and distinguish the Sámi in relation to other people, my aim is to move beyond such a common interpretation and unfold the garment's everyday aspects and explore how its production and use are interwoven with the Lulesámi's emphasis and ongoing creation of personal and social well-being. The chapters address, in their different ways, the three main themes of this study. The first is concerned with the various ways in which the gáppte and its use affect people's sense of self and relations to others, and the factors influencing such diverse experiences. The second theme focuses on how the learning to make the garment, rather than involving a fixed set of skills, is based on an ongoing practical and sensuous engagement with the world. I demonstrate that novices not only learn the technical skills of producing a garment to be worn, but that they are also encouraged to develop certain social skills and virtues for living a good life. The third theme is constituted by an examination of the productive activities within the domestic sphere, which often go unnoticed as they cannot easily be seen or measured through tangible evidence, but which affirm and strengthen the making of a convivial society. Through the analysis I draw and build on current anthropological debates on material culture by showing how craftsmanship is a self-transforming experience which encompasses a complete way of being, traversing and merging immaterial and material realms of life. I also wish to contribute to feminist debates by drawing attention to how the ‘personal' and ‘domestic' are intimately intertwined with larger historical, political and social processes.
