Fuzzy Rock Typing: Enhancing Reservoir Simulation And Modeling By Honoring High Resolution Geological Models, Vida Gholami
Fuzzy Rock Typing: Enhancing Reservoir Simulation And Modeling By Honoring High Resolution Geological Models, Vida Gholami
Graduate Theses, Dissertations, and Problem Reports (ETD)
Rock typing is an essential part of building geologic model for an asset. Millions of dollars are invested in logs, core measurements, SCAL studies, and geological interpretation that result in definition of different rock types. Rock types overlap and do not have crisp boundaries.;Upon definition of rock types for a series of geological formations geoscientists use approximation of multiple and overlapping rock types to identify a dominant rock type for any grid block in a reservoir simulation model. This defeats the original purpose of performing detail geological, petrophysical studies as far as reservoir flow models are concerned.;The objective of this …
Consolidation Of Parental Monitoring Variables And Scales: Preliminary Evidence For Construct Validity, Ryan J. Anderson
Consolidation Of Parental Monitoring Variables And Scales: Preliminary Evidence For Construct Validity, Ryan J. Anderson
Graduate Theses, Dissertations, and Problem Reports (ETD)
The aim of the present study was to improve definitions of parental monitoring constructs by reducing the domain of content from which researchers have sampled in previous investigations. For example, between the years of 1991 and 2007 researchers developed at least 49 different parental monitoring scales comprised of a total of 310 questions or items. Visual inspection of these scales as well as thorough review of the parental monitoring literature suggested that researchers primarily were interested in assessing five domains of content (the sum of which is described as parental monitoring). These five domains of content are (1) adolescent perceptions …
The Effects Of Aquaculture Production Noise On The Growth, Hearing, Disease Resistance, And Survival Of Rainbow Trout (Oncorhynchus Mykiss) And Methods For Minimizing Noise In Fiberglass Aquaculture Tanks, John W. Davidson Iii
Graduate Theses, Dissertations, and Problem Reports (ETD)
Intensive aquaculture systems, particularly recirculating systems, often require noise producing equipment such as pumps, blowers, and filters that inadvertently increase sound levels within the culture environment. These systems are often very effective at culturing healthy, fast growing fish; however, the potential impacts of underwater noise on fish within intensive aquaculture systems have not been evaluated. Limited research suggests that subjecting fish to noise could result in impairment of the auditory system, reduced growth rates, and increased stress. The studies presented within this manuscript were conducted to gain a better understanding of aquaculture production noise and its potential impacts on rainbow …

The Riotous Presence In American Literature And Culture, Rebecca Skidmore Biggio
The Riotous Presence In American Literature And Culture, Rebecca Skidmore Biggio
Graduate Theses, Dissertations, and Problem Reports (ETD)
This project seeks a comprehensive understanding of riot as an operating principle in American history and culture---a principle variously revealed in, explored, or obscured by literature produced by popular and political novelists at the turn of the twentieth century. In defining riot as a presence, I identify as central to US history a haunting incoherence between fundamental cherished ideals of representative government and the use of violence or threats of violence to assert the privilege of one group through the subjugation of another.;Because representations influence the way we characterize historical events both prospectively and retrospectively, I conduct my investigation through …
Ergot Alkaloid Biosynthesis In Aspergillus Fumigatus : Association With Sporulation And Clustered Genes Common Among Ergot Fungi, Christine M. Coyle
Ergot Alkaloid Biosynthesis In Aspergillus Fumigatus : Association With Sporulation And Clustered Genes Common Among Ergot Fungi, Christine M. Coyle
Graduate Theses, Dissertations, and Problem Reports (ETD)
Ergot alkaloids, indole-derived mycotoxins, interact with multiple monoamine neurotransmitter receptors and cause disease in exposed individuals. They have been well studied in the ergot fungus, Claviceps purpurea, and have been reported in some closely related grass endophytes, as well as the distantly related opportunistic human pathogen Aspergillus fumigatus. A. fumigatus, which sporulates prolifically, produces clavines, specifically festuclavine and fumigaclavines A, B, and C in association with asexual spores and the total mass of alkaloids constitutes over 1% of the spore mass. These alkaloids differ from those of most clavicipitaceous fungi, which consist of different clavines and often more complex lysergic …

Novel Methods For Producing Cellulose Nanocrystals From Lignocellulosic Materials And Cellulose Nanocrystals Reinforced Polymer Nanocomposites, Paul Busumafi Filson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Cellulose nanocrystals (nanofibers) represent a new emerging biological source of reinforcing biofillers. In this dissertation, we report the results of a study to produce cellulose nanocrystals from recycled pulp, hardwood and pine dissolving pulps using maleic acid, ultrasonic-assisted (sono-chemical treatment) and enzyme-mediated hydrolysis followed by fragmentation of cellulose crystallites using ultrasonic treatment. Additionally, the effect of two modes of heating: conventional and microwave, on enzyme-mediated and maleic acid hydrolysis were investigated. Cellulose nanocrystals yields from maleic acid hydrolysis of lignocellulosic materials were lower than that obtained from endoglucanase mediated hydrolysis of lignocellulosic materials. Sonochemical treatment of lignocellulosic materials produced both …

Cellular Mechanisms Responsible For Development Of Sensitivity Of The Bovine Corpus Luteum To Prostaglandin F2 Alpha, Madhusudan P. Goravanahally
Cellular Mechanisms Responsible For Development Of Sensitivity Of The Bovine Corpus Luteum To Prostaglandin F2 Alpha, Madhusudan P. Goravanahally
Graduate Theses, Dissertations, and Problem Reports (ETD)
Prostaglandin F2 alpha (PGF2alpha) brings about regression of the bovine corpus luteum (CL). This luteolytic property of PGF 2alpha is used in beef and dairy cattle to synchronize estrus. A limitation of this protocol is an insensitivity of the early CL to luteolytic actions of PGF2alpha. The mechanisms underlying this differential luteal sensitivity are poorly understood. Therefore the main objective of the current study is to understand the cellular mechanism of luteal insensitivity. The developing CL has a maximum number of PGF2alpha receptors; therefore differences in signaling events might be responsible for luteal insensitivity. Hence differential gene expression at two …
Carl Mcintire: Fundamentalism, Civil Rights, And The Reenergized Right, 1960--1964, Bobby G. Griffith Jr.
Carl Mcintire: Fundamentalism, Civil Rights, And The Reenergized Right, 1960--1964, Bobby G. Griffith Jr.
Graduate Theses, Dissertations, and Problem Reports (ETD)
Carl McIntire (1906--2002), the fiery Fundamentalist leader, led a crusade against the civil rights movement between 1960 and 1964. This thesis explores McIntire's protests of civil rights legislation as they complicate the standard narrative which is typically southern focused and hones on racial arguments against civil rights, while McIntire was based in New Jersey and made political arguments. Additionally, McIntire's language of American traditionalism, anti-communism, and libertarian economics parallel the rise of modern conservatism which culminated in the candidacy of Barry Goldwater for President. This thesis shows that McIntire and other religious and social conservatives built momentum through organization and …

Abnormal Ecg Search In Long-Term Electrocardiographic Recordings From An Animal Model Of Heart Failure, Pisut Raphisak
Graduate Theses, Dissertations, and Problem Reports (ETD)
Heart failure is one of the leading causes of death in the United States. Five million Americans suffer from heart failure. Advances in portable electrocardiogram (ECG) monitoring systems and large data storage space allow the ECG to be recorded continuously for long periods. Long-term monitoring could potentially lead to better diagnosis and treatment if the progression of heart failure could be followed. The challenge is to analyze the sheer mass of data. Manual analysis using the classical methods is impossible. In this dissertation, a framework for analysis of long-term ECG recording and methods for searching an abnormal ECG are presented.;The …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Testicular cancer is the most common cancer occurring in males between the ages of 15 & 35. Although testicular cancer holds a survival rate of 99% when detected and treated early, prior research shows most males do not perform regular testicular self-examinations. This research examined the role of fear appeals in the revised protection motivation theory (PMT) model to predict the performance of testicular self-examination behaviors in college males. An experiment was conducted among a convenience sample of 156 (N = 156) males enrolled in a state university. All males answered a set of questions measuring their threat appraisal concerning …
Health Promotion During Midlife: The Influence Of Internal Health Locus Of Control And Future Time Perspective, Sarah T. Stahl
Health Promotion During Midlife: The Influence Of Internal Health Locus Of Control And Future Time Perspective, Sarah T. Stahl
Graduate Theses, Dissertations, and Problem Reports (ETD)
Health promoting behaviors are typically categorized as behaviors that move individuals towards optimal health while concurrently decreasing one's susceptibility to disease and illness (Becker & Arnold, 2004; Breslow, 1999). When compared to other developmental age periods, less is known about health promotion in midlife (Merrill & Verbrugge, 1999). Thus, the present study examined the relations among demographic variables, future time perspective, internal health locus of control, and middle-aged adults' engagement in health promotion. Data from 109 middle-aged adults between the ages of 40 and 66 were collected via an online survey. Results indicated that the data fit the model poorly …

Parent-Child Interaction Therapy: The Effects Of Parental Attention Components On Children's Verbalizations And Attending-To-Task Behaviors., Ashley B. Tempel
Parent-Child Interaction Therapy: The Effects Of Parental Attention Components On Children's Verbalizations And Attending-To-Task Behaviors., Ashley B. Tempel
Graduate Theses, Dissertations, and Problem Reports (ETD)
Various evidence-based behavioral parent training programs are theoretically designed to target parenting skills that enhance parent-child interactions. Many similarities exist across the empirically-supported interventions, however programs also include unique components (e.g., use of reflections in Parent-Child Interaction Therapy). Empirical examination of individual components is necessary to inform components that promote or deter intervention effectiveness and efficiency. An empirically established association among language delays, behavior difficulties, and poor longitudinal outcomes further supports a need for identification of facilitative components. Currently, examinations of individual components have largely targeted the effects of praise and time-out. Despite clinical assertions that additional components serve important …
