Steady State Inviscid Flow Around Semi-Infinite Axisymmetric Bodies, Louay N. Mohammad

LSU Historical Dissertations and Theses

The steady-state penetration mechanism is utilized in a number of in-situ testing -instruments such as the cone penetrometers, and piezometer probe due to faster and more economical analysis of soil parameters.

In order to bring a more comprehensive understanding to the mechanism of cone penetration, the shape and scale effects of cones should be investigated. Considering the steady state nature of these problems, this study focuses on the simulation of penetration of axisymmetric bodies in inviscid, incompressible fluids.

The wide variety of cone penetrometers introduces com­plicated mixed boundary conditions. A finite element code is written in order to determine the …

An Experimental Facility For The Study Of Capillary Instability Of Liquid Jets, Niehua Chow

LSU Historical Dissertations and Theses

An overview of the instability of laminar Newtonian liquid jets in air is given, and the experimental procedures used by previous investigators are described. It is shown that empirical data are still needed for design purposes. For a systematic improvement of existing mathematical models through experimental data, a facility is designed, constructed, and tested for measuring the breakup length of jets and the size distribution of the drops. It consists of a flow system, an electro-optical detector and a signal conditioner. The performance of the electro-optical detector is shown to be good. The output signal from the electronics is a …

LSU Historical Dissertations and Theses

Radiation induced solution polymerization of acrylamide was studied at 80(DEGREES)C in tubes with diameters of 6, 2.29, 0.89 and 0.38 mm. The tubes were filled with aqueous solutions of 3% acrylamide, 10% NaCl and sufficient neutralized orthophosphoric acid to produce a specific radioactivity of 1 mCi/ml. of dissolved ('32)P. Distinctly higher initial rates of increase of solution viscosity were observed with increasing tube diameter. Kinetic studies were done also with 3% acrylamide in 0, 5 and 10% salt solutions at 81.5(DEGREES)C and 28(DEGREES)C; the reaction induced by external irradiation from ('60)Co. Other systems studied were 1 and 1.5% acrylamide in …

A Comprehensive Study Of Black Students Attending An Historically Black University: Selected Characteristics, Experiences, Level Of Satisfaction, And Similarity To Other College Populations., Charles Ruffin Burchell

LSU Historical Dissertations and Theses

Although a large body of literature exists on the characteristics and experiences of black students attending predominantly white colleges and universities, very little empirical research on blacks attending predominantly black colleges and universities is available. Existing studies usually lack comparative groups of black and white students who attend predominantly white colleges and universities, hence it is difficult to determine the unique characteristics of the blacks who attend black colleges. To remedy this situation the present study surveyed a representative group of black students attending a publicly-supported black university. The purpose of the study was to determine unique or attractive features …

A Quantitative Evaluation Of Landsat For Monitoring Suspended Sediments In A Fluvial Channel., Soon Tae Kim

LSU Historical Dissertations and Theses

Since the launch of Landsat-1 July, 1972, the orbital remote sensing system has made significant contribution to earth science research. Landsat's repetitive "earth observations" are of great value for monitoring changes in earth surface conditions through time. Investigation of suspended sediment concentrations in natural water bodies is one of the major areas of Landsat applications. An attempt has been made to evaluate the utility of Landsat Multispectral Scanner (MSS) digital data for monitoring suspended sediment concentrations in a natural river channel using Tarbert Landing, Mississippi on the lower Mississippi River as the test site. Specific purposes of the study were: …

Jack London's South Sea Narratives., David Allison Moreland

LSU Historical Dissertations and Theses

Although Jack London is recognized as one of the most popular American fiction writers in the world, critics of American literary naturalism have tended to rank him considerably below the other well-known naturalists: Frank Norris, Stephen Crane, and Theodore Dreiser. The consensus has been that London wrote too much, too hastily, and weakened his art by imposing "ideas" (Darwinian, Spencerian, Nietzschean, Marxian) upon his narratives. However, in recent years a serious reevaluation of "the boy wonder of the naturalist carnival" has begun. As a master of the action narrative, Jack London, who both mirrored his age and anticipated later twentieth-century …

Speciation Of Environmental Pollutants By Gc-Aa And By Esca. Purification Of Water At Ultratrace Levels Of Heavy Metals And Complexation Studies By Electrochemical Methods., Ileana Aurea-Leon Rhodes

LSU Historical Dissertations and Theses

Speciation of environmental pollutants is essential for potential toxicity evaluations. It is important to determine what is the original chemical form of the pollutant when released in the environment as well as all possible reaction products and their potential hazards. The media through which these pollutants are transported in the environment are also of importance. Heavy metal pollutants usually occur in very low concentrations in the environment, therefore, very sensitive techniques are required for the determination of these metals. A GC-AA method was developed that allowed the simultaneous determination of PbEt(,4) and of PbEt(,3)Cl in gaseous and liquid samples. This …

Soot Formation From Toluene., Ten-See Wang

LSU Historical Dissertations and Theses

Synthetic fuels will likely have a higher aromatic content than petroleum-based fuels. This aromatic character will result in increased soot formation and increased flame radiation. Since the kinetics of soot formation is poorly understood, it is very difficult to design combustors using aromatic fuels. A laser beam attenuation technique was utilized to study the kinetics of soot formation from toluene and other selected fuels over the temperature range 1400-2500 K and the pressure range 2.5-10 atmospheres. Detailed soot yield studies show that the aromaticity of the hydrocarbons determines their sooting characteristics. At low temperatures, the condensation, polymerization, and dehydrogenation are …

Development And Evaluation Of Corn-Cowpea Mixtures As Protein Sources For Nigerian Infants., Enoch Nwankwo T Akobundu

LSU Historical Dissertations and Theses

The feasibility of producing a low cost, easy to use, and flatulence-free product from corn and cowpeas for Nigerian children was investigated. Cowpea slurry was naturally fermented for 48 hours at room temperature. The pH dropped from 6.38 to 4.20. In fermentation with the yeast, pichia guilliermondii Y-2075, for 72 hours at room temperature, the pH dropped to only 5.60. Soaking and wet milling resulted in nutrient losses. Drum drying of the product did not significantly reduce lysine levels, 90% being biologically available in most samples. Products with good biological value as measured by PER in excess of 2.0 were …

The Confederate Defense Of Mobile, 1861-1865. (Volumes I-Ii)., Arthur William Bergeron Jr

LSU Historical Dissertations and Theses

The people of Mobile, Alabama, supported the secession of their state from the Union in January 1861, and thousands of her able-bodied men served in the Confederate army from 1861 to 1865. Recognizing the city's strategic importance as a port and major railroad center connecting the eastern and western sections of the new nation, the Confederate government moved quickly to provide adequate defenses for Mobile. Confederate soldiers occupied and began to strengthen Fort Morgan and Fort Gaines, which guarded the main channels leading into Mobile Bay. The Confederate Navy Department converted several steamers into gunboats and began construction of four …

This research concerns the cross-validation of the ABCP instrument on a sample of clinic and nonclinic youngsters. Results from a total of 810 questionnaires, 300 from subjects seen in clinics and 510 from nonclinic subjects, were submitted to a principal …

Hydroisomerization Of Pentane And Hexane Mixtures On Zeolite Catalysts., James Jerome Spivey

LSU Historical Dissertations and Theses

Pure component and mixtures of pentane and hexane were hydroisomerized on Pd-H-mordenite and Pd-H-faujasite at 465(DEGREES)F, 100 to 300 psig, 6.2 to 6.6 w/hr/w, and 10/1 to 18/1 H(,2)/hydrocarbon mole ratio. The activity of both these catalysts was comparable to other developmental catalysts reported in the literature. Results showed that on the mordenite catalyst, the first order rate constant for n-C(,5) decreased on dilution with n-C(,6) while the n-C(,6) rate constant increased on dilution with n-C(,5). On the faujasite catalyst, the rate constant for both n-C(,5) and n-C(,6) decreased from the pure component values on dilution. Models were proposed for …

The "Southern Review": An Episode In Southern Intellectual History, 1935-1942., Ronda Cabot Tentarelli

LSU Historical Dissertations and Theses

This is a study of the Southern Review, a cultural quarterly published at Louisiana State University from 1935 to 1942, and edited by Charles Pipkin, Cleanth Brooks, and Robert Penn Warren. The Review is shown to be an important part of American intellectual history in the thirties and forties, of the Southern Renascence in literature, the history of LSU, and the careers of its editors and contributors. That the Review was more than a literary quarterly (thus the label "cultural quarterly") is evident in its contents. Besides fiction, poetry, and literary criticism, the magazine published Southern, political, and philosophical articles. …

The Conversion Of Manganese (Ii) Oxide To Manganese (Ii) Sulfide: Effect Of Variable Solid Properties. (Volumes I And Ii)., David Anthony Caillet

LSU Historical Dissertations and Theses

A study of the effect of variable solid properties on the kinetics of the reaction of spherical manganous oxide pellets with hydrogen sulfide gas was performed. This study resulted in a major modification of the grain model to allow for radial solid property variations due to reaction and/or sintering. It was shown that this new model did the original constant property grain model. A complete experimental study was made of the effects of exposure to high temperatures (sintering) and the effects of the reaction itself on the structural properties, notably the specific surface area and porosity, of the solid reactant …

An Experimental And Mechanistic Study Of The High Temperature Thermal Decomposition Of Methanol, David Leslie Miller

LSU Historical Dissertations and Theses

The thermal decomposition of methanol (CH3OH) was studied in4 both conventional and single-pulse shock tubes over the temperature and pressure ranges 950-2000 K and 1*5-12.5 atm., respectively. In both studies, highly diluted CH3OH mixtures in Ar were shock heated behind reflected waves. In the conventional shock tube infrared emission at both 3.47 and 9.56 M>m was monitored in order to measure CH3OH concentration as a function of time. The CH3OH concentration profiles were characterized by overall global expressions. Quenched samples from the single-pulse shock tube were analyzed by gas chromatography. The data obtained from the two sets of experiments …

Land Loss In Coastal Louisiana (U.S.A.), N. J. Craig, R. Eugene Turner, J. W. Day Jr.

Faculty Publications

This paper examines causes and consequences of wetland losses in coastal Louisiana. Land loss is a cumulative impact, the result of many impacts both natural and artificial. Natural losses are caused by subsidence, decay of abandoned river deltas, waves, and storms. Artificial losses result from flood-control practices, impoundments, and dredging and subsequent erosion of artificial channels. Wetland loss also results from spoil disposal upon wetlands and land reclamation projects.

Total land loss in Louisiana's coastal zone is at least 4,300 ha/year. Some wetlands are converted to spoil banks and other eco-systems so that wetland losses are probably two to three …

The Biomechanics Of The Carpometacarpal Joint Of The Thumb., Chinjen A. Ou

LSU Historical Dissertations and Theses

Data collected from six left forearms of fresh human cadavers were used to deduce the functional behavior of the muscle-tendon units acting upon the carpometacarpal (CMC) joint of the thumb. The data supplied direct information regarding tendon excursions and was used to derive moment arms of each tendon over the normal range of thumb motion. Preparation of the cadaver hands included replacement of the eight muscle-tendons crossing the joint with surgical steel suture material and immobilization of the interphalangeal joint and the metacarpophalangeal joint by insertion of a Kirschner-wire (K-wire) through the intrameduallary canal of the phalanges of the thumb. …
