An Ecological Study Of The Foraminifera Of Mason Inlet, North Carolina, Daniel N. Miller Jr.

Masters Theses

"Mason Inlet. North Carolina is a lagoonal marsh area with warm-temperate water, the salinity ranging from fresh to salt water. Nine collecting stations comprise an ecological gradient across the environment.

Forty-two species of foraminifera are recorded from the inlet, ranging in their affinities from brackish water to open-sea facies. Several extensions of range are recorded both northward and southward.

Substratum conditions apparently control the distribution of foraminifera within the inlet. Clean, fine sand provided the largest faunal populations. A depauperate assemblage was found in an inorganic, argillaceous substratum. The largest population of arenaceous forms was found at the channel through …

The Transformation Of The Aluminum-Zinc Eutectoid Alloy At Subcritical Temperatures, Thomas Joseph Burke

Masters Theses

"Interest in the mechanism of the austenite eutectoid transformation in iron-carbon alloys, especially as produced by the isothermal sub-critical techniques introduced by Davenport and Bain, has resulted in the application of similar heat treatment studies to the eutectoid transformations in other alloy systems. The study of the eutectoid transformation is of both fundamental and industrial interest because past experience has shown that these studies yielded much information concerning the nature and mechanism of the changes in eutectoid alloys during the decomposition of the phase stable at high temperatures and has also contributed much toward the development of new properties to …

Safety And Health In Mining, John Philip Lacke

Masters Theses

"The mining industry has long been criticised severely because of its high rate of accident occurrence. Statistics, which, however, are not strictly comparable show that the accident-frequency rate in all mining is currently about three times and the accident severity rate is about seven times as great as the average for general industrial work in the United States. Figures such as these are by no means comforting to mining men. They constitute a challenge to the industry that cannot be ignored.

It must be remembered that any type of mining is more hazardous than most or the other major occupations. …

A Study Of The Dissolution Of Titanium In Acids With Emphasis On Hydrofluoric Acid, Ping-Chao Chen

Doctoral Dissertations

"Titanium is practically a new metal. Although it was discovered by W. Gregor in 1791, the pure metal was not prepared until 1910 by M. A. Hunter, and it is only very recently that tremendous interest has been focused on this new metal, as evidenced by the activities of numerous leading laboratories and pilot plants.

The reasons that Ti is gaining increasing attention may be attributed to the natural abundance of Ti ores in reasonable concentration and, what is more important, to its unusual combination of physical and chemical properties. According to F. W. Clark’s classical geochemical data, Ti amounts …

Efficiency Studies Of The Effect Of Moisture On The Power Consumption Of Mine Scrapers, Georges J. Vigier

Masters Theses

"Many years of practice have resulted in the standardization of several types of scrapers which are now commonly manufactured for use in mining. Although experience has brought out much information on scraping operations, no systematic studies of the efficiency of mine scrapers have been carried out before the experimental works done in the last few years at Missouri School of Mines and Metallurgy. "Purpose of Problem": The purpose of this present study is to consider the effect which moisture in the muck has on the efficiency as regards power consumption and amount of material scraped, of different types of mine …

The Economic Spacing Of Contraction Joints In Reinforced Concrete Pavements, Wilbert Frederick Wegener

Masters Theses

"Structurally, there are two types of joints used in concrete pavements: (a) the tied, or permanently-closed joint; and (b) the open or free type of joint. The permanently closed joint utilized tie-steel of some form to keep the joint from opening. Usually, this steel is in the form of short individual bars extending across the joint and bonded to both slabs (designated as "tie-bars") or in the form of distributed reinforcement. The remaining method of classification, that of refering [sic] to the joint purpose, gives the expansion joint, contraction joint, and warping joint. An expansion joint is, as the name …

Principles And Practices Controlling The Use Of Earthmoving Equipment, Woodrow John Latvala

Masters Theses

"The purpose of this study is to show how the efficiency in earthmoving projects can be increased by the application of engineering principles. Efficiency can be increased by choosing equipment to fit the given set of conditions; and, having chosen the equipment, operate it at its maximum efficiency. In order to choose the right equipment it is necessary to study the conditions under which the equipment must operate. It is then necessary to study the machine in order to ascertain its adaptability to the existing conditions"--Introduction, page 1.

A Study Of Mine Scraper Efficiency On Materials Of Different Specific Gravities, Kermit Guy Rowley

Masters Theses

"The purpose of this study is to determine the effect that the specific gravity of the material scraped has on the power consumption and the efficiency of the common types of mine scrapers. As scraper weight, rope speed, and moisture content of the muck are important factors affecting the power consumption and efficiency, these variables are the ones considered for each type scraper. Two materials of different specific gravities are used in the study with an equal number of tests run on each material"--Introduction, Purpose of Problem, page 2.

The Precipitation-Runoff Relationship On The Grand River Basin Of Missouri And Iowa, J. Kent Roberts

Masters Theses

"In the study of a drainage basin which is to be utilized for water supply or water power, there is frequently a dearth or complete lack of runoff data, though precipitation data are almost always available. The Water Resources Branch of the United States Geological Survey maintains gaging stations on various streams and runoff records from these streams are available from their publications and offices. Many of these runoff records cover a considerable number of years, and are entirely sufficient for use in an analysis of any drainage basin covered by such data. Some of these gaging stations have not …

Effect Of Removed Web-Section On Critical Load For I-Beam Columns, Henri Simon Rigo

Masters Theses

"This investigation deals with a series of column tests of aluminum I-sections which have a perforated web. Specifically, the tests show that the weight is decreased without decrease in strength. Several basic assumptions are made in the design of a column. The physical action of a column is idealized in the derivation of formulae which will predict within reasonable limits the load which the member will sustain. In a given installation of non-homogeneity of material, kinks, uneven bearing, lack of symmetry due to riveting or welding, stress concentration and many other disturbing factors not in agreement with these assumptions may …

A Study Of Missouri Flint Clay, Edmond Preston Hyatt

Masters Theses

"The problem is one of attempting to explain the peculiar nature of Missouri Flint Clay and to expand the knowledge concerning it. Among the questions for which answers are sought are: What makes Missouri Flint Clay so hard? What happens to Missouri Flint Clay when it is ground? What is the mineralogical constitution of Missouri Flint clay?"--Introduction, The Problem, page 1.

The Effect Of Calcium Chloride On Air-Entrained Concrete, Gerard Francis Hofstaedter

Masters Theses

"The essence of the problem is not fully set forth in the title in that all aspects are not covered. In this case, the term "effect" means how the compressive strength and the modulus of elasticity vary with the addition of calcium chloride...Many pages will be found concerning the relative merits of plain concrete versus air-entrained concrete. All phases of the problem have been covered thoroughly. Investigations have been conducted on both plain and air-entrained concrete to determine the compressive strength, flexural strength, durability and workability"--Introduction, page 1.

Effect Of Unionism On Cost Of Coal, Subrahmanya Padmanabhan

Masters Theses

"Coal is not only the base of our civilization and a key to our continued high standard of living but it is also playing a leading part in the recovery of Europe and other backward nations of the world. Our dependency upon coal as a basic source of energy is growing greater and greater every day. Some day atomic power may be our principal source of energy but the list of technical obstacles that block the way for widespread and commercial use of atomic energy is a long one. Unlike its competitors, such as petroleum and natural gas, the reserves …

A Comprehensive Traffic Survey Of Phelps County, Missouri, Clifford D. Muir

Masters Theses

"The purpose of this study is two fold. The first of these purposes is to serve as a pattern or guide for any county or township wishing to conduct a comprehensive traffic survey. The second purpose of this study is to provide traffic classification and other data on a typical county system of rural roads. Today, many counties in the United States are faced with the problem of inadequate roads, due to the modernization of the American farm. While they realize this problem exists, may county governments have developed no organized method of studying and determining their needs...When the author …
