Herman Frasch (German Immigrant Chemist, Standard Oil, Petroleum; Ohio, Louisiana)., William Ralph Sutton

LSU Historical Dissertations and Theses

Herman Frasch (1851-1914) invented the hot-water process for mining sulphur that permitted the exploitation of the rich deposits beneath the coastal plain of the Gulf of Mexico. The Frasch process enabled the United States to become self-sufficient in the production of this important industrial mineral and the major supplier to the world. Frasch's new idea was to inject steam into the underground deposit to melt the sulphur and then pump the liquid to the surface. He patented the process in 1891 and first demonstrated its technical success at Sulphur, Louisiana in 1894. Initially plagued with problems due to the high …

A Study Of The Texture Measurement Definition Problem (Image Analysis)., Ramon Emilio Vasquez-Espinosa

LSU Historical Dissertations and Theses

The problem of texture measurement definition is studied. A theory is presented in order to overcome the problem. This theory includes a conceptual framework for the general measurement definition problem. This framework is based on the concepts of a perceptual transform, a perceptual space, a measurement transform and a similarity transform. Using this conceptual framework and a particular choice for the similarity transform, a set of requirements are defined. These requirements can be used to create a formal method for defining measurements off the GLC matrices. The formal procedure is based on preserving perceptual relationships among textures. To apply this …

Effect Of Feedback On Selected Teaching Behaviors Of Agricultural Teacher Educators., Walter Stephen Woodley

LSU Historical Dissertations and Theses

This study was conducted to determine the impact of student feedback upon the teaching behavior of agricultural teacher educators. An experimental pretest posttest control group design was used for the study. Ninety-seven agricultural teacher educators were surveyed and 62 (63.9%) agricultural teacher educators and their students participated on both the initial and final assessment. A modification of the Tuckman Teacher Feedback Form (TTFF) was used to measure the agricultural teacher educators' self-perceptions and their students' perceptions.

"They Fought Splendidly!": The Struggle For Port Hudson (Civil War, Louisiana, Military)., Lawrence Lee Hewitt

LSU Historical Dissertations and Theses

This dissertation examines the Confederate occupation of Port Hudson, Louisiana, and the Union efforts to capture the bastion during the period August 1862-July 1863. Though it recounts the garrison life of the soldiers, it emphasizes governments. Throughout the period under consideration, the Confederate government's objective in garrisoning Port Hudson and Vicksburg was to maintain the vital Red River supply-line. That waterway facilitated the east-west flow of manpower, munitions and foodstuffs between the heart of the Confederacy and the Trans-Mississippi. The United States government recognized the importance of this supply-line and made control of the Mississippi River one of its primary …

High Temperature Combustion Of Selected Chlorinated Hydrocarbons., David Leslie Miller

LSU Historical Dissertations and Theses

A study combining ignition delay measurements and quenched product distributions from shock-tube experiments with chlorinated hydrocarbons has been conducted to develop a better understanding of the combustion characteristics of these compounds which are candidates for incineration. The ignition delay times of selected C(,1), C(,2) and C(,6) chlorinated hydrocarbon- stoichiometric oxygen mixtures have been measured behind reflected shock waves at a pressure of 1.8 atm over the temperature range 1200-1700K. Studies were also conducted with mixtures of chlorinated and nonchlorinated hydrocarbons to examine the effect of chlorine atom/hydrogen atom ratio on ignition delay behavior. The results indicate that contrary to conventional …

The Velocity And Shape Of Gas Slugs Rising In Vertical Tubes And Rectangular Slots., Henry Valma Nickens

LSU Historical Dissertations and Theses

The rise of a large gas bubble, or slug, through a closed, vertical, liquid-filled channel of infinite length has been investigated by means of potential flow theory. Three channel geometries are considered: (1) the circular tube, (2) the two-dimensional rectangular channel and (3) the three-dimensional rectangular slot. The effect of inter- facial surface tension is explicitly accounted for by application of the Kelvin-LaPlace equation, thus making the bubble shape an integral part of the solution. For the circular tube of radius R and diameter D, the solution is expressed in terms of the Stokes Stream Function which consists of an …

Thirtysix treatments, with three levels of air temperature, three levels of moisture (of rice after exposure in the dryer), and four levels of tempering, were performed on Saturn variety, medium grain rice, parboiled under fixed conditions. The dried and tempered rice samples were then moisture equilibrated under room conditions and subjected to standard milling procedures. Analyses were performed to evaluate color, texture, protein, and strength characteristics of the milled rice. A time-based study of kernel hardness and strength properties was …

Mechanical And Chemical Conditioning As An Aid In Hastening Drying Rate Of Ryegrass Forage., Marcel Tsang Mui Chung

LSU Historical Dissertations and Theses

Laboratory tests were conducted to evaluate four types of mechanical, two types of chemical and combinations of mechanical-chemical conditioning treatments on drying rate and quality of ryegrass forage. Mechanical treatments ranged from cuticle abrasion to crushing of the stems while the chemicals were expected to remove or disrupt epicuticular waxes. The statistical design was a randomized block with two observations per cell. Analysis of variance results yielded highly significant block-treatment interaction for all variables examined. Two types of drying pattern were indicated. For treatments restricted to the plant surface as caused by the brushes and chemicals, the drying pattern was …

A History Of Louisiana, 1939-1945. (Volumes I And Ii)., Jerry Purvis Sanson

LSU Historical Dissertations and Theses

This dissertation is a study of Louisiana's political, social, and economic development during World War II. Louisiana in 1939 was a rural, agricultural, poorly-educated, racially segregated, one-party, southern state. By 1945, however, many aspects of life in Louisiana had changed. Louisiana's political development during the war years was marked by the temporary displacement of the Longite faction of the Democratic party by the reform faction of the party. Even though reformers Sam Jones and James H. Davis captured control of the executive branch of the state government, Longites remained strong in the legislature and in minor state offices. The Longite …

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 …

The Habitat And Cost Of Production Of Domestic Petroleum Resources., John Daniel Grace

LSU Historical Dissertations and Theses

The geologic characteristics of an oil field, most importantly its depth and surface area, have significant impacts on the average cost of extracting petroleum. These characteristics of petroleum habitat constitute a measure of "deposit quality," as ore grade does in the production of metals. This measure can be used to separately evaluate the effects on cost, over time, of changing depost quality and technological advance. A sample of 156 U.S. fields, with average estimated ultimate recovery of 50 million barrels, was analyzed to quantify the cross-sectional differences in average production cost on the basis of depth, area, productive capacity, reservoir …

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 …

Where Did The Bayogoula Dance; Why Do They Sing No More: A Reexamination Of The Archaeology Of The Bayou Goula Area, Iberville Parish, Louisiana, Glen G. Fredlund

LSU Historical Dissertations and Theses

Two objectives are undertaken. The first is the identity of the two 18th century archaeological sites at Bayou Goula. A reexamination of the ethnohistorical and -archaeological records of the area reveals that the Bayou Goula site traditionally accepted as an aboriginal village is actually the site of an early French settlement. A second archaeological site recently discovered is hypothesized to be the 1699 village of the Bayogoula and Mugulasha.

The second objective was a methodological study of aboriginal ceramics from this recently discovered site. The type-variety system is rejected in favor of an attribute or "modal" analysis in evaluating competing …

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, …

Deltaic Sedimentation In Eastern Atchafalaya Bay, Louisiana., Ivor Llewellyn Van Heerden

LSU Historical Dissertations and Theses

A new Mississippi delta--now in the subaerial growth phase--is building in Atchafalaya Bay, south-central Louisiana, as the result of a natural upstream di-version. Early studies of this event documented gross accretion in Atchafalaya Bay. The present study focuses on subaerial delta lobe responses, stratigraphic development, and sedimentation processes that are incorporated into a model for delta growth. A sedimentological research program undertaken in the eastern half of the Atchafalaya delta has shown that two distinct stages of subaerial delta response are recognizable. The first (younger) re-sponse consists of channel extension, bifurcation, and development of sinuous overbank channels. A latter, more …

LSU Historical Dissertations and Theses

The overall objective of this study was to gather basic information about livestock programs in the Ivory Coast, and to determine factors that may be impeding the successful accomplishment of these programs. One hundred and two livestock producers were interviewed--72 who were members of SODEPRA and 32 who were not. The data from the field study were coded onto computer sheets and transferred to punched cards and percentages and Chi-Square Values were calculated. The major dependent variable, membership in SODEPRA, was related to the independent variables in the study. Chi-Square values were used to determine if there was a significant …

The Effectiveness Of Video Technology In Safety Training At An Industrial Site., Robert Steven Miller

LSU Historical Dissertations and Theses

Industry has long held to the belief that accidents are caused and they can be prevented. To support this belief, industry in the United States has allocated vast resources for accident prevention. The rationale for this allocation of resources rests on the concern for employees' well-being, federal and state regulations, and the profit incentive. In order to test the most feasible and effective program to generate safety awareness and teach specific safety skills, a system of daily reinforcement using an in-plant cable tablevision capability was conceptualized, designed, implemented and tested. This study presents the findings for the Safety Minutes program …
