Mass Transfer Of 2,4,6-Trinitrotoluene And Lower Chlorinated Benzenes From Sediment Into Water., Marti Charleen Blad

LSU Historical Dissertations and Theses

Bioremediation and phytoremediation are in their infancy and this research addresses concerns for application of these technologies. This laboratory and mathematical modeling effort predicts the pollutant flux from soils and sediments to the overlying waters. Little work has been done on transport in surface waters such as the slow moving and stagnant areas of the southern U.S. Mass transfer is a proposed rate limiting factor for biological transformation when using phytoremediation or natural attenuation. The research quantified mass transport of two dfferent contaminants, TNT and chlorinated benzenes, under different advective conditions. The TNT study was part of a "riffle-bed reactor" …

Plant Uptake Of Desorption Resistant Organic Chemicals From Sediments., Cesar Miguel Gomez Hermosillo

LSU Historical Dissertations and Theses

Two types of wetland plants, a woody species, black willow ( Salix nigra), and a non-woody, the macrophyte three-square bulrush (Scirpus olneyi), were used in laboratory studies to evaluate relationships between sorption, plant uptake, translocation and transpiration of phenanthrene, a model polycyclic aromatic hydrocarbon and chlorobenzene, a model chlorinated benzene from the reversible and desorption-resistant compartment of a sediment for Phenanthrene (PHEN) and a wetland soil for chlorobenzene (CB). The wetland soil is from The Petro Processors Inc. site (PPI), a 77-acre CERCLA facility located about 10 miles north of Baton Rouge, Louisiana. Other studies have evaluated the plant uptake …

On K-Conjugacy Classes Of Maximal Tori In Semi-Simple Algebraic Groups., Uroyoan Ramon-Emeterio Walker

LSU Historical Dissertations and Theses

An attempt was made to make this a self-contained reading. The first three chapters are intended to provide the necessary background. Chapter one develops the tools needed from Galois Cohomology. Chapter two is a brief description of involutions, and in chapter three we define the notion of (linear) algebraic group, we give some examples and discuss some of their properties. In chapter four, we discuss some variants of the classical Skolem-Noether theorem, requiring only that the subalgebra have a unique faithful representation of full degree over a separable closure. We verify that we can extend every isomorphism to the whole …

A Treatment-Based Reading Assessment., Gary Joseph Duhon Jr

LSU Historical Dissertations and Theses

Each year a large number of students are identified as having problems in reading. The methodology for the identification of reading problems has been established and in practice for several years, however, the tools necessary for the identification of remediation procedures appropriate for the individual student lack this level of refinement. This study is an attempt at refining current assessment practices for the purpose of identifying remediation procedures that are effective on the level of the individual student. A conceptual model of learning (instructional hierarchy) was combined with a treatment based functional assessment methodology, resulting in a behavior analytic approach …

The Selection Of Narrow Wavebands For Optimizing Water Quality Monitoring On The Great Miami River, Ohio Using Hyperspectral Remote Sensor Data

Journal of Spatial Hydrology

Remote sensing data were successfully used to estimate spatial and temporal variation of optical water quality parameters such as chlorophyll a, turbidity and Total Suspended Solids (TSS) of the Great Miami River, Ohio. During the summer of 1999, spectral data were collected with a hand-held spectroradiometer, a laboratory spectrometer and airborne hyperspectral sensors. Approximately 80 km of the Great Miami River were imaged during a flyover with a Compact Airborne Spectrographic Imager (CASI) sensor. Approximately 10 km were imaged during a second flyover to repeat coverage of the urban and industrial influences around the city of Dayton, Ohio. Instream measurements …

A Study Of Factors That Influence Academic Success Of Black American Middle School Males, Harvey S. Hicks Iii

Theses and Dissertations

The Black American male has had to face and endure many physical, emotional, and psychological hardships since his ancestors arrived in this country as slaves. One of those hardships has been his constant status as a second-class citizen. Throughout his history in America, the Black male has received unequal pay, unequal justice, unequal medical care, unequal treatment, and unequal education. Yet, despite the circumstances and the odds, there have been Black males who have achieved in many fields. However, even today, in the field of education, achieving academically is not an endeavor most Black males pursue.

This study investigated some …

Accurate Parameter Estimation For An Articulatory Speech Synthesizer With An Improved Neural Network Mapping, Hali̇s Altun, Tankut Yalçinöz, K. Mervyn Curtis

Turkish Journal of Electrical Engineering and Computer Sciences

Neural network (NN) applications have recently been employed to extract the parameters of an articulatory speech synthesizer from a given speech signal. Results from these attempts showed that a single NN is insufficient to cover all of the possible configurations uniquely. Moreover, apart from their computational advantages, NN mapping is so far not superior to the other mapping techniques [1]. Thus there is a clear need to improve NN solution to the inverse problem. Results from our earlier experiments with an articulatory speech synthesizer have shown that the statistical characteristic of the articulatory target pattern vectors can be exploited for …

Scalar Wave Diffraction By A Perfectly Soft Infinitely Thin Circular Ring, Fati̇h Di̇kmen, Ertuğrul Karaçuha, Yury Alexanderovich Tuchkin

Turkish Journal of Electrical Engineering and Computer Sciences

A new strong mathematically rigorous and numerically effective method for solving the boundary value problem of scalar (for example acoustic) wave diffraction by a perfectly soft (Dirichlet boundary condition) infinitely thin circular ring is proposed. The method is based on the combination of the Orthogonal Polynomials Approach, and on the ideas of the methods of analytical regularization. As a result of the suggested regularization procedure, the initial boundary value problem is equivalently reduced to the infinite system of the linear algebraic equations of the second kind, i.e., to an equation of the type ( (I + H) x = b …

Orientations Of Graphs Which Have Small Directed Graph Minors., Glenn Randolph Berman

LSU Historical Dissertations and Theses

Graphs are characterized by whether or not they have orientations to avoid one or more of the digraphs K&ar;3 , S&ar;3 , and P&ar;3 . K&ar;3 , S&ar;3 and P&ar;3 are created by starting with a triangle, a three point star, or a path of length three respectively, and replacing each edge with a pair of arcs in opposite directions. Conditions are described when all orientations of 3-connected and 4-connected graphs must have one or more of the above digraphs as a minor. It is shown that double wheels, and double wheels without an axle, are the only 4-connected graphs …

Analysis And Mathematical Modeling Of Autonomously Oscillating Yeast Cultures., Abdelqader M. Zamamiri

LSU Historical Dissertations and Theses

The conditions that precede the onset of autonomous oscillations in continuous yeast cultures were studied in three different types of experiments. It was found that the final state of the culture depends on the protocol used to start-up the reactor. Reaching the desired operating point by slow dilution rate changes gave rise to different final states, two oscillatory states and one steady state, depending on the rate of change in dilution rate. The multiplicity of stable states at a single operating point is not explained by current distributed models and points towards a segregated mechanism of these oscillations. The ability …

It Rarely Occurs: Mock Juror Reactions To A Physician's Defense In A Lack Of Informed Consent Case., Douglas J. Zickafoose

LSU Historical Dissertations and Theses

Three experiments examine how expressions of probability concerning why a risk involved in a medical procedure was not disclosed influence mock juror decisions (e.g., liability, culpability, and damage awards). Across all three experiments, no differences were found in mock juror judgments of liability due to the probability expression used, be it verbal, quantitative, percentage, or frequency. Furthermore, differences in mean damage awards were only found when psychological uncertainty was manipulated using a frequency expression. However, an examination of the median damage awards suggests that some expressions of probability are likely to result in higher damage awards than others. Thus, while …

Risk Based Urban Watershed Management Under Conflicting Objectives, Vladimir Novotny, David E. Clark, Robert J. Griffin, Douglas Booth

Economics Faculty Research and Publications

Ecological impairment and flooding caused by urbanization can be expressed numerically by calculating the risks throughout the watershed (floodplain) and along the main stems of the streams. The risks can be evaluated in terms of the present and/or future. This article describes the methodologies for ascertaining the risks in the Geographical Information Systems (GIS) environment. The objectives of urban flood controls and ecological preservation/restoration of urban waters are often conflicting and, in the past, the sole emphasis on flood control led to destruction of habitat and deterioration of water quality. An optimal solution to these two problems may be achieved …

A Ring-Closing Strategy For The Synthesis Of Β,Γ-Unsaturated Δ-Lactones, Erbing Hua

Masters Theses

Spiro β,γ-unsaturated δ-lactones and fused β,γ-unsaturated δ-lactones are integral to a large number of naturally occurring compounds exhibiting a diverse range of biological activity. A new synthetic route to β,γ-unsaturated δ-lactones, consisting of a three-step sequence, has been investigated for the synthesis of these kinds of pharmacological intermediates. Ring closure of a β-hydroxy acid by dehydration, providing a 4-vinyl substituted β-lactone, and its ring expansion/rearrangement are the two key steps in this protocol. The results have proved that this new method is efficient and quite expeditious. One spiro and four fused β,γ-unsaturated δ-lactones were synthesized through this protocol albeit in …

The Synthesis Of 2-Indenylphenols: Potential Ligands For Transition Metals, Yoon Jae Kim

Masters Theses

The syntheses of 2-(2-indenyl)-phenol and 2-(1-indenyl)-phenol via a three-step sequence have been developed. In the first steps of the sequence, a Grignard reagent formed from 2-iodoanisole or 2-bromoanisole reacted with 1-indanone or 2-indanone in yields that ranged from 11.3% to 67.2%. The second step consisted of acid-catalyzed dehydration of the alcohol formed in step 1 to make a 2-inenyl anisole; yields in the second step were 45.2% to nearly quantitative. Finally, demethylation of the 2-indenyl anisole was achieved with AlBr₃ in ethanethiol in yields ranging from 52.9% to 0 %. Each product was characterized by ¹H and ^{13 …}
