Cloning and physical mapping of DNA complementary to potato leafroll virus RNA
(1987)
Potato leafroll virus (PLRV) was aphid-transmitted from potato (Solanum tuberosum cultivar Russet Burbank) to ground cherry (Physalis floridana), where it was maintained by serial aphid transmission. Serological and plant ...
The effects of the comprehensive behavior management system on student achievement, instructional climate, and the management of student behavior in selected junior high and middle schools in Texas
(1987)
The purpose of this study was to determine the effectiveness of the Comprehensive Behavior Management System by Harris as applied in five selected junior high and middle schools in Texas. Of primary interest were the areas ...
The development and genetic evaluation of racing capacity in Thoroughbreds
(1987)
Genetic parameters were estimated for three measures of racing capacity in Thoroughbreds; (1) mean seconds per furlong of the race (MSPF-Race); (2) mean seconds per furlong of the stretch (MSPF-Stretch), the portion of the ...
Characterization of sequences involved in polyadenylation of Eukaryotic pre-mRNA
(1987)
The major objective of this study was to characterize the regions of poly(A) signals, which in addition to the AAUAAA are sufficient for accurate and efficient polyadenylation. In addition, this study was designed to test ...
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 ...
