The Magnetocardiogram A New Approach To The Fields Surrounding The Heart, R. A. Stratbucker, C. M. Hyde, S. E. Wixon

Department of Electrical and Computer Engineering: Faculty Publications

Experiments have been conducted which reveal the existence of a detectable magnetic field associated with cardiac electrical activity. The relationship between the magnetic record and the electrocardiogram has been explored and it is shown that under certain conditions of axis orientation the voltage induced into a toroidal sensing element around the heart has the form of the first time derivative of the electrocardiogram. A formula based on Maxwell's equations has been developed to relate these two phenomona.

Methods For The Determination Of The Thermal Conductivity Of Solids., A. M. Sivadasan

Masters Theses

"The thermal conductivity of materials is of considerable practical and theoretical interest. Numerous publications on this subject have been presented with widely varying approaches and applications being made. Perhaps for no other thermal property are the published results so widely divergent and subject to such great uncertainty, particularly at high temperatures. This is partly due to unsolved difficulties in measurement, but perhaps to an even greater extent to the fact that the thermal conductivity of a material depends on its physical characteristics as well as some environmental factors such as humidity and temperature. In the case of metals or alloys, …

A Study Of Sprinkler Uniformity Evaluation Methods, Baha Dabbous

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use of water in homes, on farms, by factories, and for recreational purposes has been increasing rapidly. Water use has doubled in the last three decades. By 1980, water use is expected to be double the current use. In arid and semi-arid regions, the practice of successful profit-yielding agriculture often depends on irrigation. Irrigation is, in turn, dependent upon a water supply which is limited. The highest possible efficiency should be maintained if maximum utilization of the available water resources for irrigation is desired. Sprinkler irrigation allows, among other things, high water application efficiencies with good distribution uniformities.

Fm 55-8, Transportation Intelligence, 1961, Robert Bolin , Depositor

United States Department of Defense Military Intelligence

In 1961, American military intelligence was decentralized. The Army was responsible for all intelligence concerning foreign armed forces. Within the Army, the technical services – Transportation Corps, Signal Corps, Ordnance Corps, etc. – were responsible for intelligence concerning analogous organization in foreign organizations. The Transportation Corps was responsible for intelligence concerning foreign transportation equipment and services. Since there was no centralized American military intelligence organization, the Transportation Corps was tasked with supplying intelligence concerning foreign road and rail networks and waterways as well as ports and landing beaches and airfields.

This manual defines transportation intelligence and prescribes Army doctrine concerning …

Evaluation Of The Thermal Properties Of Plastic Laminates, Luciano Sedillo

Chemical and Biological Engineering ETDs

To insure the proper application of newly developed materials, it is necessary to evaluate their physical and chemical properties. In the case of plastic laminates for use as heat barrier material, thermal diffusivity is an important property. Thermal diffusivity is the parameter which governs the rate of temperature change through a material. Its value depends upon the chemical composition and the physical structure of the material and its temperature.

A Flotation Process For The Concentration Of New Mexico Oolitic Iron Oxide Ores., William C. Rahmig

Chemical and Biological Engineering ETDs

The vast expansion in the production of steel in the twentieth century has turned the eyes of the steel industry toward sources of low grade iron ore. Evidence of this is dramatically presented in a recent issue of Steel Facts. Fifty two percent of the iron ore mined in the United States was concentrated before shipment to the consumers. This is an increase of 25 percent over the amount concentrated a decade ago. The marked increase will continue as technological advances light the way for economical are treatment.

The Use Of Ferrophosphorous And Manganese Ore In High Density Concrete For Radiation Shieding, Robert A. Crist Jr.

Such an aggregate was found to be available in Socorro, New Mexico. The Socorro Manganese Corporation has a stockpile of over 7,000 tons of high-grade manganese ore (specific gravity = 4.5) potentially suitable as a heavy aggregate, and some of which was used for this research. Along with the manganese ore was used ferrophosphorous, a very heavy aggregate manufacture by the Victor Chemical Works (specific gravity = 6.5), to obtain a range of densities that would …

New Genera And Species Of Myripristid Fishe~ In The Gulf Coast Cenozoic, Known From Otoliths (Pisces, Beryciformes), Donna L. Frizzell, C. Kurt Lamber

Missouri School of Mines and Metallurgy Bulletins

Studies of fossil and Recent otoliths (sagittae) supply an important line of evidence, bearing on classification of teleost fishes, supplementary to that of anatomy, osteology, and "phylogenetic" paleo ichthyology.

Squirrelfishes (" Holocentridae" of authors) are generalized forms in which evolutionary divergence of some magnitude is reflected in unpreservable details of anatomy, inconspicuous skeletal structures, and striking differentiation of the sagittae. Otoliths show the holocentroid complex to consist of one homogeneous unit (l\fyripristidae, elevated) and another more heterogeneous group (Holocentridae, restricted). These lineages have been separated at least since the middle Eocene.

A revised classification, based on available lines of evidence …

Evaluation Of Protective Paint Films On Steel By X-Ray Diffraction Techniques, Donald Charles Knobeloch

Masters Theses

"Paints and related organic materials provide the most widely used means of protecting metals against corrosion. While corrosion measurements are based on a full range of quantitative methods in physical and analytical chemistry, the basic problem of evaluation work in the field of paint chemistry has been characterized by empirical testing procedures. Field tests are still of major importance and secondly, the relative value of paints may be predicted through exacting laboratory tests. However, the results of accelerated exposure tests have never successfully been correlated with service experience despite the efforts of many laboratories over a period of 35 years …
