Thermal Conductivity Of Sodium Chloride Within The Temperature Range 375°K To 637°K, Paul E. Ohlsen

Masters Theses

"The transport of heat in dielectric solids is attributed entirely to lattice waves whereas in metals there is in addition a transfer by the flow of valence electrons. The thermal conductivity of a non-electrical-conductor is limited by a number of scattering processes giving rise to thermal resistances. Scattering results from impurity atoms and from vacancies and dislocations within the crystal structure and from the interaction of the lattice vibrations amongst themselves. Scattering also occurs at the boundaries of the crystal. The thermal resistance of an ideal crystal at low temperatures is due almost entirely to boundary scattering and at high …

The Effect Of Ph On Phase Reversals Of Protein-Stabilized Emulsions, Samuel Arthur Bradford

Masters Theses

"The phase reversal of an emulsion from a system in which oil droplets are dispersed in a water medium to a system in which water droplets are dispersed in oil is dependent upon the interfacial characteristics of the liquids and the emulsifying agent being used, as well as the volume ratio of the two liquid phases. A preliminary investigation at this institution has indicated a possible relationship between phase reversal and the isoelectric point of gelatin used as the emulsifying agent. Since the properties of proteins vary so greatly with the hydrogen ion concentration, particularly near their isoelectric points, research …

Geothermometry At The Balmat No. 2 Mine, New York By The Fes-Zns System, Bruce R. Doe

Masters Theses

"Definition Of The Study. The study consists of an investigation of the variation in the temperature of formation of sphalerite on the 500 and 1500 ft levels of the Balmat zinc deposit at Balmat, New York. A subsidiary investigation was performed on the use of x-ray fluorescence as a means of chemical quantitative analysis. Twelve samples of sphalerite from the 500 ft level and 13 samples from the 1500 ft level were analyzed for atomic percent iron content by measuring Zn/Fe x-ray fluorescent ratios. The x-ray fluorescent ratios were standardized by ''wet" quantitative analysis. The results of the analyses are …

The Effect Of Metallic Naphthenates On The Oxidation Of Linoleic Acid, David Elliott Troutner

Masters Theses

"It has been known for many years that certain metallic soaps catalyse the drying of oils. A great deal of information is available concerning the use of these soaps, but there is little knowledge of the actual manner in which the soaps catalyse drying. As the drying is known to be an autoxidation reaction, it is generally believed that the soaps must affect the oxidation of the oil in some way. The work described in this thesis was undertaken to gain some knowledge of the mechanism of the catalysis, and to correlate the effect of the soaps on the drying …

Pre-Cambrian Geology Of Washington County Area, Missouri, Gordon Blair French

Masters Theses

"The Problem.

Washington County, Missouri contains a limited number of outcrops of pre-Cambrian igneous rocks, the majority of which are in the extreme southern part of the county. The known association of lead ore with buried or partially buried pre-Cambrian igneous knobs and ridges in this part of Missouri has led the St. Joseph Lead Company to prospect in areas known to contain these features. In its exploration program, the St. Joseph Lead Company has drilled a number of prospect holes which have encountered other occurrences of pre-Cambrian igneous rocks within the limits of Washington County. This drilling, correlated with …

Physical Properties Of Concrete At Early Ages, Peter G. Hansen

Masters Theses

"One of the principal types of heavy duty pavements in use in Missouri and in many other states is that known as rigid type portland cement concrete.

There have been two major trends in this type of pavement design. One of these trends is the use of short slabs, i.e., 15 to 25 feet, with no reinforcement. Another trend consists of concrete slabs containing distributed reinforcement such as wire mesh or reinforcing bars with joints occurring at fairly large intervals of 50 to 100 feet. As loads on the highways have increased the designers have increased the slab thicknesses and …

The Thermal Conductivity Of Potassium Chloride At Elevated Temperatures, Wendell D. Miller

Masters Theses

"The transport of heat in solids is attributed to the combined effect of the quantized vibrations of lattice points, or phonons, and the flow of valence electrons. In dielectric solids, the thermal conductivity is due almost entirely to phonons, while in metals the latter method preponderates. Scattering processes in dielectric solids, giving rise to thermal resistance, also serve to limit the thermal conductivity. Scattering results from vacancies, dislocations, interstitial atoms and phonon interaction. Crystal boundaries also function as scattering points and in crystals of small dimensions, this process is the most pronounced conductivity-limiting factor. At low temperatures the thermal resistance …

Geology Of The Northwest Quarter Of The Washington Quadrangle, Missouri, James Anthony Martin

Masters Theses

"This report presents the results of detailed mapping of the geology of the northwest quarter of the Washington Quadrangle, Missouri. Extensive mapping and stratigraphic work have been done in St. Louis and St. Charles Counties to the east and in Callaway and Boone Counties to the west. These two well studied areas are separated by approximately 45 miles. This study adds geologic information to the area immediately between the above locations. In this area a gentle regional dip to the north permits a study of sediments ranging in age from lower Ordovician in the south to late Paleozoic and Pleistocene …

Engineer's Day . . . 1955, Missouri School Of Mines And Metallurgy

Engineer's Day

The Future Is NOW! . . .

The scene above is an experimental hydrogen bomb explosion at the AEC Pacific Proving Grounds. Practically unknown as recently as fifteen years ago, atomic energy is now a vital, universal force, shaping the lives of all mankind. Its frightening flash bursts across the face of our earth and gives us all cause for fear and wonder.

Yet we may hope, too. Patterns of world civilization are changing with bewildering rapidity. The scientific and industrial ways of yesterday are obsolete today. Tomorrow’s methods will show no less impact of change.

The world of science …

Further Studies Of Vapor-Liquid Equilibria Of Methanol-Ethylene Glycol-Water, Herbert Benjamin Sachs

Masters Theses

"The freezing points of the ternary system methanol-glycol-water have been investigated by Conrad, Hill and Ballman. The vapor-liquid equilibria of the same system was studied by Sjoberg. These investigations were carried out to determine the properties of the system relative to its possible use as an antifreeze mixture.

Since Sjoberg's work in 1948, the improved Othmer equilibrium still has been introduced for vapor-liquid experimental determinations. It is therefore the purpose of the present investigation to evaluate the use of this still, compare results with those obtained by Sjoberg, and analyze ternary mixtures for the entire range of glycol concentrations.

Correlation Functions For Use In Small Angle X-Ray Scattering, James Edwin Thomas Jr.

Masters Theses

"Thus, the determination of the structure of the material, and obtaining a distribution function which will enable the theoretical scattering to be predicted is the major problem.

In this work the diffraction material shall be considered to contain scattering regions of identical geometrical forms at such a distance from one another that they will essentially scatter the incident beam independently of their closest neighbor. An effort will be made to determine a correlation function characteristic of these forms, which may be interpreted as a distribution function, that might allow the low angle scattering pattern to be predicted. This correlation function …

Separation Of Germanium, Lead, Zinc, And Cadmium By Anion Exchange, Franklin Maynard Hill

Masters Theses

"The object of this study was to investigate the ion exchange behavior of germanium and apply the anion exchange technique for the separation of germanium, cadmium, lead, and zinc.

A new interest in germanium has developed because of its recent industrial application as a semi-conductor. Analytical methods for the separation and analysis of germanium in low concentrations have not been perfected. Krause and Johnson, in a recent review, discussed and evaluated a number of methods.

Most of the methods for the analysis of germanium require a preliminary separation. The analytical methods for germanium reported in the literature are troublesome and …

Addition Of Ketene To Ethylene Oxide, John Philip Friedrich

Masters Theses

"The object of this work was to study the reaction between ethylene oxide and ketene, and if possible, to isolate and identify the postulated γ-butyrolactone. Although the results could hardly be described as completely gratifying, they were at least in a sense positive. Many possibilities remain with regard to further modifications of the experimental work on this problem, however it is the author's sincere wish that this investigation will serve some useful purpose in the future"--Introduction, page 4.

The Thermal Conductivity Of Sodium Chloride At Elevated Temperatures, Howard Martin Brown

Masters Theses

"The thermal conductivity of solids has been attributed to a combined effect of the quantized vibration of the lattice points, called phonons, and the flow of valence electrons. In nonconductors the thermal conductivity is due almost entirely to phonons, as was shown by Debye, whereas in metals the conductivity is due mostly to the flow of valence electrons. After Debye, Peierls calculated the lattice conductivity at elevated temperatures using quantum mechanics and demonstrated that it is proportional to 1/T. There are not enough data available to substantiate any theory but what data there are seem to indicate a mixed conductivity …

A Study Of Tunnel Demolition By Hasty Methods, Richard Lee Bullock

Masters Theses

"The use of explosives to construct obstacles which impede the enemy or close his routes of communication has long been employed by our armies. They have developed fairly effective methods for destroying bridges, setting up road craters and constructing abatis. However, one phase of obstacle construction, that of tunnel demolition, has been neglected in that no procedures or methods have been formulated which will aid in the proper destruction of tunnels.

At the present time, under the auspices of the Department of the Army, The Missouri School of Mines and Metallurgy is conducting a research program on tunnel demolition. The …
