Research About Low Permeability Measurement, Jun He Jan 2013

Research About Low Permeability Measurement, Jun He

Theses and Dissertations

Petroleum exploration and production from shale formations have gained great attention throughout the world in the last decade. Producing the hydrocarbons from shale is challenging because of the low porosity and permeability. It is imperative to investigate permeability of the shale formations in order to better understand the performance of wells that are producing hydrocarbons from shale. Permeability is also one of key parameters in modeling fluids flow in matrix in reservoir simulation. Due to the low or very low permeability, the measurement of permeability is time consuming and expensive. These factors often limited the ability to perform permeability measurement …

Learning Approach And Learning: Exploring A New Technological Learning System, Ester Aflalo, Eyal Gabay Jan 2013

Learning Approach And Learning: Exploring A New Technological Learning System, Ester Aflalo, Eyal Gabay

International Journal for the Scholarship of Teaching & Learning

This study furthers the understanding of the connections between learning approaches and learning. The research population embraced 44 males from the Jewish ultraorthodox community, who abide by distinct methods of study. One group follows the very didactic, linear and structured approach of a methodical and gradual order, while the second group follows the multi-directional approach that emphasizes global, abstract thought. The participants, who for ideological reasons hardly use computer technology, were exposed to a new technological learning system. The study employed the qualitative research method, with the research tools including textual analysis, observations and guided in-depth interviews. The findings show …

Interpreting Racial Politics: Black And Mainstream Press Web Site Tea Party Coverage, Benjamin Rex Lapoe Ii Jan 2013

Interpreting Racial Politics: Black And Mainstream Press Web Site Tea Party Coverage, Benjamin Rex Lapoe Ii

LSU Doctoral Dissertations

This dissertation seeks to understand the cultural meanings of the black and mainstream press’ online interpretations of the tea party. Little research exists on the modern black press; what does exist shows that unless the story is about race, the black press mirrors the mainstream press. To my knowledge, no research exists comparing the two presses on a racial issue in an online environment. This dissertation will fill that hole. The tea party narrative was, and continues to be, an intricate story for journalists to tell. Resonant myth offers interpretative templates for journalists to use for crafting cultural meaning while …

Essays On The Impact Of Income On Family And Child Well-Being, Christian Werner Raschke Jan 2013

Essays On The Impact Of Income On Family And Child Well-Being, Christian Werner Raschke

LSU Doctoral Dissertations

In this dissertation I offer three independent studies that each contribute to the literature on the impact of income on family and child well-being. I present three essays that investigate three different contexts and sources of income variation. First, I investigate the extent to which an unconditional cash transfer to families in Germany that is intended to benefit children actually translates into an improvement in the circumstances related to child well-being. Next, I analyze how shocks to mothers’ earnings impact their demand for health inputs during pregnancy, and how this affects the health of the newborn child. The fourth chapter …

Optimizing Peak Gust And Maximum Sustained Wind Speed Estimates From Mid-Latitude Wave Cyclones, Timothy Andrew Joyner Jan 2013

Optimizing Peak Gust And Maximum Sustained Wind Speed Estimates From Mid-Latitude Wave Cyclones, Timothy Andrew Joyner

LSU Doctoral Dissertations

Wind storms cause significant damage and economic loss and are a major recurring threat in many countries. Maximum sustained and peak gust weather station data from multiple historic wind storms occurring over more than three decades across Europe were analyzed to identify storm tracks, intensities, and areas of frequent high wind speeds. Wind surfaces for maximum sustained and peak gust winds were estimated based on an anisotropic (directionally-dependent) kriging interpolation methodology. Overall, wind speed magnitudes and high intensity locations were identified accurately for each storm. Directional trends and wind swaths were also consistently located in appropriate locations based on known …

Influence Of Various Health Beneficial Spices On Some Characteristics Of Yogurt Culture Bacteria Lactobacillus Acidophilus, And Sensor Acceptability Of Spicy Probiotic Yogurt, Margie Michelle Sanchez-Vega

LSU Doctoral Dissertations

There is a pronounced public awareness about herbal remedies. Garlic and ginger have antibacterial properties and prevent cardiovascular diseases. Onion and turmeric decrease the risk of diabetes and like garlic, they have anticancer properties. Streptococcus thermophilus, Lactobacillus bulgaricus and Lactobacillus acidophilus are lactic acid bacteria that produce lactase and reduce the symptoms of malabsorption. Earlier work has shown the influence of spice extracts but the influence of pure spice juice on yogurt culture bacteria is not known. Characteristics of yogurt culture bacteria were measured by suspending freshly thawed cultures in 0.1% peptone water (growth), acidified MRS broth (acid tolerance), MRS-Thio …

Memory For Elements Of A Complex Scene : Binding And The Influence Of Attention, Stephanie L. Martin Jan 2013

Memory For Elements Of A Complex Scene : Binding And The Influence Of Attention, Stephanie L. Martin

LSU Doctoral Dissertations

Memory of a complex event includes a multitude of features (e.g., objects, people, and actions) as well as the overall context (e.g., going to a picnic). To recall a complex event you must bind together these features and context into an episodic memory representation. This process of binding creates the subjective experience that certain details belong together. In two experiments, I examined whether particular types of information are bound together (object-to-object, object-to-context) within a memory representation of a scene and how attention may influence this process. Participants viewed a series of scenes and their attention was drawn to some objects …

On Identifying Critical Nuggets Of Information During Classification Task, David Sathiaraj Jan 2013

On Identifying Critical Nuggets Of Information During Classification Task, David Sathiaraj

LSU Doctoral Dissertations

In large databases, there may exist critical nuggets - small collections of records or instances that contain domain-specific important information. This information can be used for future decision making such as labeling of critical, unlabeled data records and improving classification results by reducing false positive and false negative errors. In recent years, data mining efforts have focussed on pattern and outlier detection methods. However, not much effort has been dedicated to finding critical nuggets within a data set. This work introduces the idea of critical nuggets, proposes an innovative domain-independent method to measure criticality, suggests a heuristic to reduce the …

Fluorescent Materials For Chemical Sensing, Brian Gerard Imsick Jan 2013

Fluorescent Materials For Chemical Sensing, Brian Gerard Imsick

LSU Doctoral Dissertations

Materials incorporating fluorescent π-electron conjugated molecular species for sensing and imaging are advantageous over other detection or identification methods such as colorimetric reporters. Fluorescent materials offer easy recognition of binding events due to the highly sensitive nature of fluorescence techniques down to the single molecule level. The properties of fluorescent molecules allow for rapid attenuation of observable readout due to the facile transport of excited state energy via both inter- and intramolecular pathways. This dissertation primarily focused on the development and study of a general platform for ratiometric fluorescent chemosensing using surface-immobilized oligomers, as well as in depth explorations of …

Emergence Of Delamination Fractures Around Casing And Its Stability, Wei Wang Jan 2013

Emergence Of Delamination Fractures Around Casing And Its Stability, Wei Wang

LSU Doctoral Dissertations

The cement sheath failures and nearby wellbore failures may lead to upward flow of drilling fluid or formation fluid, which may have significantly adverse consequences like loss of reserve and environmental hazards. In order to maintain wellbore integrity in the long term, it is expedient to examine the causes of failures around the wellbore and propose suitable numerical models to predict annulus cracks around the casing. The complex failure behavior of cement/rock interfaces observed in the laboratory experiments does not look like the behavior of linear or simple nonlinear mechanical interfaces. Cohesive zone method (CZM) with BK-form bilinear traction separation …

Quantum Simulations On Square And Triangular Hubbard Models, Kuang-Shing Chen Jan 2013

Quantum Simulations On Square And Triangular Hubbard Models, Kuang-Shing Chen

LSU Doctoral Dissertations

In this thesis we try to understand the unconventional superconducting mechanism on cuprates and organic superconductors (or sodium cobaltates) which can be modeled by a two-dimensional square- and triangular-lattice Hubbard model respectively. The formation of the superconducting dome requires explanations of feasible scenarios. Generally speaking, pairing strength is provided by magnetic fl_x001D_uctuations in the strongly correlated region and the structure of the Fermi surface in this region will favor superconducting pairings with a certain type of symmetry. For the cuprate physics, a superconducting dome composed of d-wave pairings has been identified experimentally. We study the Hubbard model on square lattices …

Ecosystem Metabolism In Coastal Plain Streams Of Southeast Louisiana : Environmental And Watershed Effects, Jonathan L. West Jan 2013

Ecosystem Metabolism In Coastal Plain Streams Of Southeast Louisiana : Environmental And Watershed Effects, Jonathan L. West

LSU Doctoral Dissertations

Since its introduction in 1956, the use of open-system, diel dissolved oxygen curves for estimating the components of ecosystem metabolism in the lotic setting have been important in determining the current ecosystem theory of streams, both spatially among multiple systems and longitudinally within the same system, as well as identifying potentially impaired systems, especially when contrasted with streams considered unimpaired. Several factors have been identified as controls on both components of ecosystem metabolism and include light, nutrients, and stable substrates for gross primary production (GPP) and a source of organic matter (OM) for ecosystem respiration (ER). Stream size is important …

Reef Fish Demographics On Louisiana Artificial Reefs : The Effects Of Reef Size On Biomass Distribution And Foraging Dynamics, Kirsten A. Simonsen Jan 2013

Reef Fish Demographics On Louisiana Artificial Reefs : The Effects Of Reef Size On Biomass Distribution And Foraging Dynamics, Kirsten A. Simonsen

LSU Doctoral Dissertations

Understanding the role that habitat plays in the life history of reef-associated fishes is particularly significant given the dramatic increase in the number of artificial reefs deployed in coastal ecosystems over the past 50 years. In the Gulf of Mexico, the oil and gas industry has added a significant amount of structure to the Louisiana continental shelf, creating the largest de facto artificial reef deployment area in the world. Noting their usefulness as fish habitat, the Louisiana Artificial Reef Program was established to convert decommissioned platforms into artificial reefs. However, very little quantitative information exists on how these habitats affect …

Complexity In Property, Meredith M. Render Jan 2013

Complexity In Property, Meredith M. Render

Articles

This article illuminates the largely misunderstood relationship between complexity and the regulation of property interests Specifically the article presents the complexity thesis a novel explanatory account of the principle of numerus clausus The principle of numerus clausus is an ancient common law rule which prohibits the customization of property interests The complexity thesis holds that the primary function of numerus clausus is to prevent the proliferation of highly idiosyncratic property interests In so doing numerus clausus provides a bulkhead against the overwhelming complexity that would ensue if customized property interests were permitted For the last fifteen years numerus clausus has …

Silica Polypeptide-Based Colloids: Physical Properties And Novel Materials, Cornelia Rosu

LSU Doctoral Dissertations

The investigation of polypeptide composite particles, PCPs, is described. The production of mesoporous and polycolloid architectures is also addressed. PCPs were prepared by both growing form and grafting to method. They consist of a core made of silica, silica-coated magnetite or silica-coated cobalt. Some of the particles were covalently labeled with fluorescein isothiocyanate. Several polypeptides were chosen for attachment on the core: poly(γ-stearyl-L-glutamate), PSLG, poly(Nε-carbobenzyloxy-L-lysine), PCBL and poly(o-benzyl-L-tyrosine), PBTY. Attachment of a well-characterized alkyne-end terminated PSLG and PCBL to an azide- functionalized particle yielded PCPs with a desired sparse coverage. A blend of techniques such as FTIR, XPS, TEM, HTEM, …

Treatment Integrity Failures Matched To Behavioral Function, Joanna Elizabeth Lomas Mevers Jan 2013

Treatment Integrity Failures Matched To Behavioral Function, Joanna Elizabeth Lomas Mevers

LSU Doctoral Dissertations

Prior research on treatment integrity has focused on either the lack of measurement of the independent variable (Peterson, Homer & Wonderlich, 1982; Gresham, Gansle & Noel, 1993; Wheeler, Baggett, Fox & Blevins, 2006; McIntyre, Gresham, DiGennaro & Reed, 2007; Sanetti, Gritter & Dobey, 2011) or on methods to increase overall levels of treatment integrity(Witt, Noell, LaFleur & Mortenson, 1997; Noell, Witt, Gilbertson, Ranier & Freeland,1997; Noell et al., 2005). Yet little research has been devoted to understanding the effectiveness of common interventions when those interventions are implemented with less than perfect integrity. The current investigation evaluated the effectiveness of using …

A Large Scale Network Model To Obtain Interwell Formation Characteristics, Seyedmohammadamin Gherabati Jan 2013

A Large Scale Network Model To Obtain Interwell Formation Characteristics, Seyedmohammadamin Gherabati

LSU Doctoral Dissertations

Limited data availability and poor data quality make it difficult to characterize many reservoirs. For reservoirs that have undergone waterflooding, production and injection data are a reliable source of information from which injector-to-producer connections can be inferred. In this research, we use well locations, injection and production rate data and well fractional flow values to develop a reservoir-scale network model. A Voronoi mesh divides the reservoir into a number of node volumes each of which contains a well. Bonds connect each of the nodes with conductance values that must be inferred from the rate data. An inverse problem is formulated …

Molecular-Level Investigations Combining Nanoscale Lithography And Atomic Force Microscopy, Chamarra Karmelia Saner Jan 2013

Molecular-Level Investigations Combining Nanoscale Lithography And Atomic Force Microscopy, Chamarra Karmelia Saner

LSU Doctoral Dissertations

In this dissertation, nanostructures of octadecyltrichlorosilane (OTS) and were prepared using particle lithography and evaluated using characterizations with atomic force microscopy (AFM). The nanostructures of OTS were used as a resist for patterning fibronectin, an extracellular matrix protein. Particle lithography provides a practical and reproducible approach to generate billions of nanostructures comprised of organic thin films or nanomaterials. A film of mesospheres can be applied as a surface mask to define the periodicity and size of nanopatterns using processes of self-assembly. A close-packed arrangement of mesospheres is produced spontaneously when monodisperse solutions of latex or silica are dried on a …

Reciprocal Peer Mentoring : Increasing The Prosocial Behavior Of Socially Neglected Students, Tai A. Collins Jan 2013

Reciprocal Peer Mentoring : Increasing The Prosocial Behavior Of Socially Neglected Students, Tai A. Collins

LSU Doctoral Dissertations

Two studies investigated the effectiveness of the Reciprocal Peer Mentoring intervention in improving the prosocial behavior of socially neglected elementary school students as measured by a Direct Behavior Rating filled out by their teachers. Reciprocal Peer Mentoring uses the methodological framework of the Check-In/Check-Out intervention (e.g. Hawken & Horner, 2003), but expands on it by using peers as mentors, adding a reciprocity component, focusing on prosocial behavior, and targeting socially neglected students. In Study 1, the effectiveness of Nonreciprocal Peer Mentoring was examined, as popular peers served as mentors for neglected peers. In Study 2, neglected or rejected students mentored …
