Comparative Petrographic, Petrochemical And Spectrographic Analyses Of The Precambrian Granitic Rocks Of Southeastern Missouri, Eva B. Kisvarsanyi

Masters Theses

"Petrographic, petrochemical and spectrographic studies were completed on selected Precambrian granitic rock samples from Southeastern Missouri. This investigation contributes to a more detailed knowledge of the Precambrian granitic rocks of this part of the state.

Petrographic analysis of forty-four thin sections of granitic rocks from the St. Francois Mountains area revealed six different granite types. These have been named the Fredericktown, Knoblick, Doerun, Graniteville, Klondike and Silvermine granites. These rocks form a large part of a composite batholith. More than one period of granitic intrusion is represented, but differentiation also contributed to the formation of this diversity of the rocks. …

A Study Of The Inlet Characteristics And Entrance Losses Of Pipe Culvert With A Flush Mounted, Sharp Edged Inlet, Luke Lea Callaway Jr.

Masters Theses

"Of all hydraulic structures, culverts are by far the most numerous. Lack of understanding of the functioning of culverts has resulted in many of them being implaced improperly and as a result, they function with less efficiency and at reduced capacity. Much has been written regarding the flow of water in open channels, culverts included, but little has been done regarding inlet conditions. It is necessary in the design of culverts, as with any other structure, that conditions which govern the operation of the structure be established. This paper is a study of the inlet conditions of a circular cross …

Water Resources Development -- An Analysis Of Economic Justification Practices Of The Corps Of Engineers, Kerwood W. Barrand

Masters Theses

"Presented herein is a brief analysis of the economic justification practices of the Corps of Engineers as commonly implemented in proposals concerning water resources projects. Where applicable, recommended methods are compared to similar methods advocated for, and accepted by, private engineering firms in similar situations.

The major problem exists in the lack of a profit motive in programs undertaken with the use of public funds. However, a profit can be said to have been realized in public works programs if the total benefits of the programs to all the people exceed the costs of these programs and, further, if the …

The Effect Of Recorded Lateral Lisping On Listener Comprehension, Leslie Gene Adkins

Masters Theses

The Problem

This experiment was designed to test the effect of misarticulation on listener comprehension. Of the many authorities who suggest that poor speaking reduces comprehension, Knower, Phillips, and Koeppel state: "Poor speaking seems to be the least effective method of presenting informative materials. There is a direct relationship between the quality of speaking performance and the amount of material recall." One of the important factors which contributes to effective speaking is correct articulation. According to Van Riper and Irwin: "If you misarticulate your speech sounds, it interferes with communication, and your speech is judged as abnormal." Articulation defects are …

The Correspondence Of Error Between The Voiced And Unvoiced Cognates “S” And “Z” In Children With Articulatory Disorders, Gerald F. Johnson

Masters Theses

Introduction

The problem as set forth in this thesis is to determine the correspondence of error between the voiced and unvoiced cognates "s" and "z" in children with articulatory disorders. It has been assumed that the correspondence of error type would be high due to the similarity of the sounds. Anderson, for example, says that "much of what is true with respect to "s" applies with equal force to its voiced analogue "z"." The problem of this research is to determine whether there is any correspondence between the respective errors on the sibilants "s" and "z" and if they correspond …

An Analysis Of The Articulation Errors In Spontaneous Speech Of One Hundred Children With Lisps, Paula C. Downs

Masters Theses

The Problem

This study is an attempt to determine the nature and relative frequency of the articulation errors shown by one hundred school children with lisps.

The Importance of Investigating the Phenomenon of Defective Articulation

The incidence of speech defects in the child population has been found to range from five percent (5%) to ten percent (10%) of the total child population. A child's speech is considered defective when the listener gives as much or more attention to the manner in which the child speaks as he does to the idea being communicated.

Field Application Of The Membrane Filter Method For Bacteriological Quality Determination Of Water, Charles Liston Gambill

Masters Theses

"The purpose of this thesis is to demonstrate the definite advantages to be realized when using the membrane filter method as an accepted procedure for the bacteriological analysis of a water; and specifically when used under emergency or field conditions such as military units in the field. These same advantages would apply to Civil Defense and other such agencies when operating under emergency or field conditions.

Data from actual tests showing techniques, equipment and procedures used and augmented by other data available from research papers will be utilized"--Introduction, page 2.

The Effects Of Fly-Ash On Dynamic Modulus Of Elasticity Of A Concrete Mortar, Bill L. Atchley

Masters Theses

"Over the last few years an increasing amount of interest has been shown in the use of prestressed concrete. As is true in many new methods of design or construction, the properties of existing materials to be used sometimes fail to meet all the desirable characteristics, and certain modifications might be advantageous. This is certainly true of prestressed concrete design and construction, in which a lower modulus of elasticity accompanied by a minimum loss in strength would be desirable. If a lower modulus of elasticity could be obtained for concrete, a lower prestressing load could be used and still maintain …

A Review Of Fossilization Processes In Different Sedimentary Environments (With Special Reference To The Time Factor Of Deposition Of Ore Minerals Associated With Fossil Material, In Particular The Coprolitic Phosphate Deposits), Giovanna Reggiori Ligasacchi

Masters Theses

"This thesis offers a cross/section through some principal fossilization processes involving organic matter (animals and plants) during and after sedimentation. The influence of different environments during fossilization is considered. The chemical composition of some classes of living invertebrates and plants is compared with the chemical composition of same organisms as found in consolidated sediments as fossils.

Some literature on carbonates, oxides, silicates, phosphates, and sulphides in fossils is reviewed with particular attention to those instances where the fossils are associated with ore minerals. Special consideration is given to the occurrence and composition of fecal matter in recent and consolidated sediments. …

Hymnody In The Liturgical Aspects Of Worship, Philip Steen

Masters Theses

The main purpose of this study was concerned with the relationship of hymns to services in the church. The author sought to answer the question, "What are the hymns that should be used for a certain service in the Church Year?” This would have to be explained from both a theological and musical viewpoint. In order to answer this question, it was necessary to include four minor areas of study (1) the history and use or hymns and hymn tunes, {2) the history and use of the Liturgical Year, (3) the elements that determine a good hymn and (4) the …

The Effects Of Ultrasonically-Induced Cavitation Upon Dissolved Oxygen, Free Carbon Dioxide, And Bicarbonate Ion Concentration In Water, Charles Alvin Wentz Jr.

Masters Theses

"Cavitation may be encountered in many scientific fields. Mechanical and civil engineers are concerned with the prevention of cavitation erosion in the design of turbines, propellers, underwater missiles, and similar structures. Biologists and physiologists are seeking more knowledge concerning the tensile strength of liquids, such as, tree sap and the formation of gas bubbles in the blood stream. Finally, the physicist and acoustical engineer must cope with the cavitation problem when working with underwater transducers, cavitation noise, and the propagation of acoustical signals through media in which cavitation is occurring.

There are many forces which hold a liquid together and …

Methods And Time Study In Mining Operations, Cyril Jones

Masters Theses

"It was the purpose of this study to evolve and present in a logical manner a method of approach from the efficiency standpoint, to mining operation problems. This, it was thought, could be best achieved by means of a method and time study program, which could examine all the operations in whatever detail was required"--Statement of the problem, page 1.

Stability Of Rectangular Plates By Arbitrary Deflection Method, James Arthur Jones

Masters Theses

"Many engineering structures use thin rectangular plates as members. These plates may be loaded and supported in numerous ways. The edges may be freely supported, rigidly supported, or supported by elastic members. The load may be applied normal to the plane of the plate, in which case the problem becomes essentially one of bending. If the load is applied in the plane of the plate, placing it in compression, the problem becomes one of stability.

This investigation is concerned with the stability of plates rigidly supported on all edges and having a compressive load applied to two opposite edges of …

Regulation Of River Bank Development Through Flood Plain Zoning, William James O'Neill

Masters Theses

"The triangular pattern of protection, evacuation and flood plain zoning, as the only truly effective and comprehensive approach to proper flood control, is substantiated in practically all technical publications on this subject by economic and engineering leaders. Yet in actual practice, at the present time, flood plain zoning is not being actively applied by any federal flood control agency and by only one of the forty-nine states faced with this common problem. This lack of direct application was probably best described recently by Walter B. Langbein, Water Resources Division Engineer, U. S. Geological Survey when he said, "Flood Plain Zoning, …

An attempt is made in this study to prepare an outline to be followed throughout the exploration in order that statistical methods can be applied to valuation problems. Particular emphasis is given to the preliminary requirements to a statistical approach. Representative parameters, sampling pattern, and sample size are discussed in separate chapters"--Abstract, page iii.

Lattice Constants, Thermal Expansion Coefficients And Perfection Of The Phase Tio, Hsiung Wei Li

Masters Theses

"TiO is one of the intermediate phases in the titanium - oxygen system with a crystal structure of the sodium chloride type. The phase extends from about 22 to 29 weight or about 46 to 55 atomic percent oxygen. A comprehensive survey of the physical properties of the phase has been made in previous investigations (see review of literature), but only impure titanium was available at that time. Therefore, some revision of the measurements had to be made. Also, neither the thermal expansion coefficients nor the temperature at which the lattice constants were measured were reported.

For precision determination of …
