Loop yagi array antennas
(1979)
A novel technique for the derivation of the current distrbutions on array antenna elements is presented. The analysis is carried out for an array of loops with arbitrary circunferences and spacings. The simultaneous ...
Biosynthetic studies on vitamin B₁₂
(1987)
The role of folates in the enzymatic formation of the porphyrin macrocycles was investigated. Uroporphyrinogen III cosynthetase-free hydroxymethylbilane synthase from Rhodopseudomonas spheroides was incubated with the ...
A follow-up study of the small group teaching approach used in the Texas Expanded Food and Nutrition Education Program/Food Stamp Project
(1987)
Since its inception in 1968, the method most commonly used in the implementation of the federally funded Expanded Food and Nutrition Education Program (EFNEP) has been that of one-to-one contact. Limited-income homemakers ...
An evaluation of specific ionic and growth parameters affecting the feasibility of commercially producing red drum (Sciaenops ocellatus)
(1987)
Seven experiments were conducted to determine whether red drum might be commercially cultured in inland salt or fresh waters. Four of these were to define specific environmental requirements, absolute and survival ranges, ...
Perceptions of training and performance in change agent roles by selected agricultural extensionists in Latin America
(1987)
The major purpose of this study was to determine what change agent roles were played by selected agricultural extensionists in Latin America, and the nature of training they received for these roles. Were these agricultural ...
Heterosis and heterosis retention for measures of female productivity of cattle of diverse biological types
(1987)
Breeding, calving and weaning records of cows produced in a diallel of Angus, Brahman, Hereford, Holstein and Jersey were used to characterize these breed types for measures of female productivity. First-generation crossbred ...
The digestive chemistry of pinto bean iron : in vitro and cannulated swine models
(1987)
The solubility, oxidation, reduction, adsorption, and reactivity of iron are known to influence its bioavailability. The purpose of this study is to investigate the above factors in digestive mixtures using spectrophotometry ...
A study of the barriers perceived as having impact on degree attainment by doctoral students in the College of Education, Texas A & M University
(1987)
The purpose of this study was to identify perceived situational, dispositional and institutional barriers which had a negative impact on doctoral students' completing their degree requirements, identify faculty perceptions ...
Simulation of vehicular impacts with safety-shaped barrier
(1987)
In the research described here, a vehicle/barrier crush model was developed and combined with a vehicle model to simulate impacts with the concrete safety-shaped barriers (CSSB). The crush model accounts for the effects ...
