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.

An Experimental Study Of The Production Of Metallic Impregnations And Coatings -- A Vacuum Process, Engle D. Southard

Chemical and Biological Engineering ETDs

The purpose of this study undertaken was threefold, (1) to design and construct an experimental vacuum apparatus to produce a metal impregnated or coated material; (2) to study some of the variables which affect the process; then (3) to examine the physical characteristics of the resultant materials. Described herein is the development and operation of a vacuum system capable of producing conditions to permit the evaporation of metals to impregnate and coat various materials. The fundamental principle involved in this process is that a rarified atmosphere reduces the temperature required for metal evaporation and protects the metal vapor from reacting …

A Study Of The Mitotic Karyotypes Of Five Species Of Culicine Mosquitoes Found In New Mexico, David A. Laycock

Biology ETDs

Karyotypic studies were made of five species of mosquitoes: Culex tarsalis Coquillett, Culex pipiens quinquefasciatus Say, Culiseta incidens (Thomson), Psorophora signipennis (Coquillett), and Aedes dorsalis (Meigen). Slides of tissue from the limb buds were prepared by the squash technique. All five species were found to have a diploid number of six. The study shows that Aedes dorsalis, Psorophora signipennis, and Culiseta incidens have virtually identical mitotic karyotypes, with two pairs of large and one pair of somewhat smaller chromosomes. Culex tarsalis and Culex pipiens quinguefasciatus have karyotypes that contain three sizes of chromosomes. In Culex tarsalis there are obvious size …

The Effects Of Operating Variables On The Adsorption Of Water From Iso-Propyl Alcohol Using Molecular Sieves, Warren P. Johnson

Chemical and Biological Engineering ETDs

The purpose of this paper is to present a study made on the effects of (1) feed concentration, (2) liquid flow rate, (3) column dimensions and (4) absorbent particle size on the selective absorption of water from iso-propyl alcohol with molecular sieves in a semi-continuous or fixed-bed operation.

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.

A Comparative Study Of The Antidiuretic Hormone Bio-Assay Using Three Species Of Bufo, Jeanne Marie Jordan

Biology ETDs

This study was designed to (1) determine and compare the sensitivity of three species of Toads of the genus Bufo to the hormone Pitressin, a commercial anti-diuretic hormone, (2) determine and compare the suitability of three species of Bufo as subjects in anti-diuretic hormone bio-assay, and (3) compare the physiological responses of the three species to the injected hormone.

Phase Equilibria In Fused Salt Systems: Binary Systems Of Plutonium(Iii) Chloride With The Chlorides Of Magnesium, Calcium Strontium, And Barium, Karl W. R. Johnson

Chemistry and Chemical Biology ETDs

Fused salt systems containing oxides have received the most attention to date, because of their occurrence in minerals and ores and their application to ceramics. The next most widely studied of group of compounds are the metal halides, particularly the metal chlorides. Despite the fact that many of the metal chlorides are hygroscopic, the salts lend themselves to experimentation because a large majority undergo stable solid-liquid transformations below 1000 degrees C, are generally ionic, and are relatively non-corrosive.

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

Civil Engineering ETDs

The scope of this thesis encompasses the investigation of the feasibilities of using a locally and/or readily available heavy aggregate for high density concrete. 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 …

Experimental Studies Of The Visible Absorption Spectrum Of Titanium (Iii) Acetylacetonate In Solutions And Rigid Glasses, Arthur L. Langhorst Jr.

Chemistry and Chemical Biology ETDs

Titanium (III) acetylacetonate was synthesized and the visible absorption spectrum was measured. A prominent absorption band, ^ymax at approximately 6000 was found with molar absorption coefficient of ~1000. The spectrum was investigated at temperatures ranging from 25 degrees C to 77 degrees K. At 7 7 degrees K the band was resolved into five well defined peaks at 4750, 5100, 5520, 5950 and 6460. An apparatus for obtaining spectrophotometric measurements of solution and rigid glasses was designed and fabricated.

Influence Of Auxins On Growth And Development Of Excised Embryos Of Pinus Ponderosa, Virgil K. Howe

Biology ETDs

The purpose of the experiment was to examine the influences of selected auxins upon seedling development post germinal cultures of excised embryos of Pinus ponderosa Laws (ponderosa pine). Seedlings were studied on an agar medium and later in quartz sand with added nutrients.

Mammals Of Mount Taylor, Valencia County, New Mexico, Eugene E. Schroeder

Biology ETDs

During the summer of 1960, three months were spent in making a comprehensive study of the kinds and ecological distribution of native mammals in and above the Transition Zone on Mount Taylor of Valencia County, New Mexico.

Mount Taylor, and old volcanic pile, rises 11,301 feet above sea level. Three boreal life zones, the Transition, Canadian, and Hudsonian were assigned to Mount Taylor.

Small mammals were collected by two sampling methods, quadrant and line trapping. However, mist nets were used for capturing bats. Quadrants were placed in various plant communities for three successive nights. Numbers and kinds of mammals recorded …

The Synthesis Of Potential Antitumor Compounds, Duane L. Aldous

Chemistry and Chemical Biology ETDs

The antitumor activity found in such ring systems as the purine, pyrazolo [3,4-d] pyrimidine, and the 8-azapurine prompted the preparation of the imidazo [4,5-d] pyridazine ring system. Castle and Seese were one of the first to study this ring system. 4-Aminoimidazo[4,5-d]pyridazine possessed some anitumor activity. This antitumor activity suggested the preparation of the 4,7-disubstituted-aminoimidazo{4,5-d]pyridazines reported here. The antileukemic activity reported for 6-purinethiol led to the synthesis of several 4- and/or 7-mono-and disubstitutedthioimidazo[4,5-d]pyridazines.

Some Aspects Of The Life History Of The Silky Pocket Mouse In New Mexico, Richard B. Forbes

Biology ETDs

Pocket mice of the subgenus Perognathus, especially those of the little known species Perognathus flavus Baird, present several interesting ecologic and taxonomic problems. A prerequisite of studies of these problems is a knowledge of extent of individual morphological variation attributable to age. A purpose of his paper is to investigate the relationship of age to size, molt and pelage, reproductive activity, and season in the silky pocket mouse. Another purpose is to analyze the summer food habits of P. flavus as revealed by study of several large series of pocket mice collected during August of 1958.

Geographic Variation Of The Hispid Cotton Rat In New Mexico, A.L. Gennaro

Biology ETDs

A total of 520 cotton rats, Sigmodon hispidus, was examined to determine the kind and amount of geographic variation of these animals in New Mexico.

The distributional history of Sigmodon hispidus in New Mexico may be revealed by a relationship between color variation of these animals and soil color of areas from which these animals were taken. This relationship suggests, firstly, that Sigmodon hispidus has occupied the southern Rio Grande Valley for a longer period of time than it has areas east of the Rio Grande Valley, and secondly, that Sigmodon hispidus has only recently occupied the Deming Plain. …

Spectroscopic Studies Of The Luminescences Of Rare Earth Chelates, Ruth Elaine Whan

Chemistry and Chemical Biology ETDs

A variety of lanthanide chelates were prepared for preliminary luminescence studies under excitation by ultraviolet light. From these, chelates of benzoylacetone, dibenzoylmethane, tribenzoylmethane, and 8-hydroxyquinoline were selected for more extensive investigation. Energies of the lowest excited singlet and triplet states of the chelates were determined. Average values of 24,500 cm^-1 and 20,500 cm^-1 respectively were obtained for the dibenzoylmethides and 24,400 cm^-1 and 21,450 cm^-1 for the benzoylacetonates. Only small variations of a few hundred wavenumbers in the positions of the excited states were found as the chelated ion was varied. This investigation in conjunction with …
