The Investigation Of Methanation Kinetics Over Ruthenium And Iron-Ruthenium Bimetallic Catalysts., Krisda Chirapongse

LSU Historical Dissertations and Theses

The catalytic properties of Ru and Fe-Ru bimetallics supported on Y-Zeolite were determined for the CO hydrogenation reaction. The results, based on the reaction at 523 K and an H(,2):CO ratio of 3:1, revealed that the addition of Fe to Ru effectively reduces the number of both H(,2) and CO active sites as determined by chemisorption experiments. Based on H(,2) chemisorption, the dispersion (number of active sites per total number of metal atoms) decreased from 0.59 with no Fe present to 0.02 with 5.9% Fe. This phenomenon was substantiated by the ESCA analysis which indicated totally reduced Ru metal particles …

A Harnack Estimate For Real Normal Surface Singularities, William A. Adkins

Faculty Publications

According to Harnack’s theorem the number of topological components of the real part of a nonsingular projective curve X defined over R is at most g(X) + 1, where g(X) is the genus of X. The purpose of the present paper is to present two estimates which can be considered analogs of Harnack’s theorem for normal surface singularities defined over R. © 1984 by Pacific Journal of Mathematics.

Stereoelectronic Effects In General Base Catalysis By Carboxylate. Theoretical Calculations And Studies In The Synthesis Of New Intramolecular Models Of Enzymatic Catalysis., Julian Tirado-Rives

LSU Historical Dissertations and Theses

The hypothesis of the existence of stereoelectronic effects in the reactions in which carboxylate acts as a general base catalyst is further studied through the use of theoretical methods. Ab initio calculations on the structures and relative energies of the syn and anti conformations of formic acid at different degrees of solvation are described. These calculations indicate that the syn conformation is more stable in aqueous phase than the anti by 11.9 (at the STO-3G//STO-3G level), 6.9 (4-31G//4-31G), and 2.5 kcal/mol (6-31G(,**)//4-31G). This last number, though, comes from single point calculations at the 6-31G(,**) level on the 4-31G optimized structure …

Coastal Louisiana Recent Land Loss And Canal Impacts, William W. Scaife, R. Eugune Turner, Robert Constanza

Faculty Publications

Annual coastal land loss in the sedimentary deltaic plain of southern Louisiana is 102 km2, which is correlated with man-made canal surface area. The relationships between land loss and canals are both direct and indirect and are modified by the deltaic substrate, distance to the coast, and availability of new sediments. Loss rates are highest in the youngest of the former deltas nearest the coast; they are lowest in the more consolidated sediments far from the coast. The average estimate for land loss at zero canal density in the six regression equations developed was 0.09%±0.13% annually, the present land loss …

Systematics Of The Water Snakes Of The Nerodia Cyclopion Complex, William Edward Sanderson

LSU Historical Dissertations and Theses

The taxonomic status of the green water snake, Nerodia cyclopion, is re-evaluated. The two recognized subspecies are compared by using a variety of standard morphological characters, and significant differences are noted. Discriminant analysis of head-scale measurements provides highly significant separation of the two taxa. Examination of specimens from the zone of parapatry reveals no evidence of recent gene flow between the taxa. Based on these morphological data, plus the biochemical and ecological data of other workers, I suggest that the subspecies be recognized as full species, Nerodia eyelopion and Nerodia floridana.

The Influence Of Missionary Activity Among The San Blas Kuna, Panama, Sheri Dixon Lane

LSU Historical Dissertations and Theses

The San Blas Kuna Indians have successfully adapted throughout four and a half centuries of contact with outside influences. Since the early 1900's they have experienced intensive missionary activity from several Christian denominations. The missions have played a significant role in the ongoing process of cultural change among the Kuna. Aside from religion, the missionaries have influenced various other spheres of Kuna life, particularly education, health care, and both internal and Kuna/Panama politics.

Although not all Kuna participate actively with the missions, knowledge about the beliefs of Christianity is widespread and the presence of the missionaries has become institutionalized into …

The Distribution Of Macrobenthos In Barataria Basin, Louisiana, Antonio Liborio Philomena

LSU Historical Dissertations and Theses

Macrobenthos and environmental variables were measured in the Barataria basin, Louisiana, at 32 stations in November 1978. Three of the stations (Lake Salvador, Little Lake and St. Denis Bayou) were sampled bimonthly from November 1977 through November 1978. Abundance, diversity, and biomass results indicated two different areas: fresh, low-salinity habitats in the upper and middle basin with high biomass, abundance, and diversity, and high-salinity habitats in the lower basin with low biomass, abundance, and diversity. Over the whole basin, crustaceans were the most abundant organisms, while the mollusks dominated the biomass. Insects, nematodes, and oligochaetes were characteristic of freshwater habitats, …

The Impact Of Sompa Elp Scores On Special Education Evaluation And Placement., Alan Lesley Taylor

LSU Historical Dissertations and Theses

The impact of the use of SOMPA Estimated Learning Potential (ELP) scores as a substitute for traditional IQ scores was examined as it affected students evaluated for special education in a large metropolitan school system. SOMPA is the System of Multicultural Pluralistic Assessment, an evaluation package developed by Jane Mercer (1979) to address concerns about bias in assessment of minority students and particularly to remove "unfair" labels of mental retardation. ELP scores represent IQ scores adjusted for the effects of sociocultural background and compared only to ethnic peer norms, with the general effect being to raise estimates of intellectual potential …

Drug Effects On Repeated Acquisition: Comparison Of Cumulative And Non‐Cumulative Dosing, Donald M. Thompson, Joseph M. Moerschbaecher, Peter J. Winsauer

Faculty Publications

Pigeons acquired a different four‐response chain each session by responding sequentially on three keys in the presence of a sequence of four colors. The response chain was maintained by food presentation under a fixed‐ratio schedule. Errors produced a brief timeout but did not reset the chain. Each day there were four 15‐minute sessions, with a 10‐minute intersession interval. Cumulative dose‐effect curves for phencyclidine, pentobarbital, and d‐amphetamine were obtained by giving an injection before each of the four sessions; successive injections increased the cumulative dose in equally spaced logarithmic steps. For comparison, non‐cumulative doses of each drug (i.e., doses not preceded …

Systematics, Redescription, And Geographic Variation Of The Blackside Darter, Percina Maculata (Pisces; Percidae)., Eugene Clifton Beckham Iii

LSU Historical Dissertations and Theses

A systematic study of the North American percid fish Percina (Alvordius) maculata (Girard) was undertaken to determine the extent and pattern of geographic variation, subspeciation, and sexual dimorphism. A brief nomenclatorial history is presented, the species is redescribed, and variation, distribution, habitat, and subgeneric relationships are discussed. Other than dorsal fin pigmentation, absence of modified midventral scales in females, and limited intrapopulational sexual dimorphism in a few morphometric characters, no variation in most of the thirty-nine characters examined is present between males and females. Morphometrics exhibited no pattern of geographic variation; however, meristic characters revealed a major trend in geographic …

Walter Georgii's Klaviermusik, Part Ii: A Translation And Commentary., Howard Gerald Aultman

LSU Historical Dissertations and Theses

In the European musical world, one of the most significant personalities of recent years was Walter Georgii (1887-1967). He was respected not only as one of Germany's most prominent pianist-pedagogues, but also as one of the most authoritative writers in the areas of piano performance and literature. One of Georgii's most important writings was a large work entitled Klaviermusik, the third edition of which appeared in 1956. The book is divided into two parts. The first part involves a comprehensive examination of the literature for solo piano and the second part involves an examination of the literature for piano duet; …
