Ethnobotany and cultural ecology of prehistoric man in southwest Texas
(1978)
Archeological excavations at Hinds Cave during the summer of 1975 yielded many hundreds of coprolites (desiccated human feces) from stratified lenses in this southwest Texas rockshelter. Radiocarbon dating established the ...
A phenomenological study of the parametric interrelationships of the inverse bipolar transistor
(1978)
A theoretical and experimental study of the interrelationships among several fabrication and design parameters of the bipolar transistor in the inverse mode is presented, with an emphasis toward its improvement for use in ...
Prices, inventories, and capacity : a theoretical-empirical study of the downstream petroleum industry
(1978)
Petroleum is the major source of energy in our society today. Few, if any, products on the market are not either made directly from petroleum or produced by a process involving petroleum at least as a fuel. Neoclassical ...
Portfolio theory and market efficiency : an application to marketing strategies of wheat producers
(1978)
In this study portfolio theory is used within the framework of an efficient market to determine the optimal marketing strategy for a representative wheat producer objective is to maximize expected utility. The problem is ...
Electrophysiological evidence against an acetaldehyde role in acute ethanol intoxication
(1978)
Some signs of acute ethanol intoxication might result from an action of acetaldehyde, the first metabolite of ethanol degradation in the liver. Support for this concept is derived largely from findings that acetaldehyde ...
Effects of evaporative salt water cooling towers on salt spray and salt deposition on surrounding soils
(1978)
Five salt water cooling towers recently constructed near Galveston Bay, Texas have been shown to contribute to salt deposition in the surrounding area. Levels as high as 1200 kg salt/ha/yr were encountered within 100 m of ...
Analysis of a cyclic gametic selection procedure in Sorghum bicolor (L.) Moenich
(1978)
A study was initiated in the spring of 1973 to evaluate the effectiveness of a cyclic gametic selection prodedure in Sorghum bicolor (L.) Moench in extracting superior gametes from a random-mating population and the ...
Advances in the development of a somatic cell genetic system for Oryza sativa (rice) via anther culture
(1978)
Oryza sativa (Rice) was anther cultured to produce callus and subsequently plants. It was shown that these plants were pollen derived and at least a portion of them were haploid. By using a cold-shock of 13°C, about 74% ...
Teaching skills essential for subject-matter specialists of the Texas Agricultural Extension Service by program areas
(1978)
The purpose of this study was to (1) identify those teaching skills which are essential for subject-matter specialists to perform within each of the Texas Agricultural Extension Service's four major program areas, that is, ...
Digraphs, automata and sandwich semigroups of binary relations
(1978)
This work is an outgrowth of recent work done investigating the transfer of information between automata and various semigroups associated with automata. Dennis Geller has introduced some relationships concerning automata ...
