Efficiency of different selection criteria for increased lamb and wool production
(1965)
Weaning and yearling data from 604 Rambouillet, Targhee and Columbia ewes of the Montana Agricultural Experiment Station, Bozeman, Montana, were used to estimate genetic parameters of production traits of economic importance. ...
An analysis of factors related to the loss and retention of freshmen students at Tarleton State College for the academic years 1964 through 1966
(1969)
Purpose [line break] The purpose of this study was to identify and analyze factors as they relate to the withdrawal end persistence of first-time-in-college students. The specific objectives which served as guidelines for ...
An instructional communication system to supplement the teaching of high school physics
(1969)
The purpose of this study was to develop instructional learning units for a blackboard-by-wire electronic communication system (BBW) and to evaluate the effectiveness of this system as a mode of instruction in selected ...
A biometrical evaluation of weight of beef cows and performance of their progeny
(1965)
Data from Experimental Station herds in Alabama, Florida, Georgia, Louisiana, North Carolina, South Carolina and Texas were included in this cooperative Southern Regional Beef Cattle Breeding Project (S-10) study. Records ...
A study of the effect of ethylene on auxin transport in cotton and its relationship to abscission
(1969)
An ethylene mediated inhibition of basipetal auxin transport in stem and petiole sections of cotton (Gossypium hirsutum L. var. Stoneville 213) was investigated using ¹⁴C labeled IAA and NAA. The purpose of this investigation ...
A consistent first-order nonlinear shell theory
(1969)
A general nonlinear theory of shells is derived. The theory is valid for large extensions, shear and rotations. The large rotations of the shell are described in detail. The measures of bending deformation then are written ...
A study of the production and propagation of high energy cosmic ray muons
(1969)
A critical reexamination of the diffusion of cosmic rays in the atmosphere is made. The incorrectness of the use of λ[subscript π], the pion attenuation mean-free-path, in the diffusion model is demonstrated. The muon ...
The isolation, identification and biochemical studies of phenolic acids from distillers dried solubles
(1969)
Studies were conducted to determine the phenolic acid composition of DDS, the sequestering property of phenolic acids and the biochemical involvement of phenolic acids (p-hydroxybenzoic and gentisic acids) in the metabolism ...
