Analysis of seed components in Upland Cotton and their associations with lint percentage
(1969)
Four cotton strains (Gossypium hirsutum L.), their reciprocal F₁, F₂ and backcross hybrids supplied the seedcotton for estimations of lint percentage and separation into five different components as follows: (1 ) embryos ...
The relation of lysine level during the growing period to sexual maturity and subsequent performance of broiler-breeders
(1969)
Two studies were carried out to determine the effects of varying the lysine level and the feeding regimes of broiler-breeder replacement pullets during the growing season on body weights, delay in sexual maturity and ...
Nitrogen utilization and bud activity in blue panicgrass (Panicum antidotale Retz)
(1969)
Blue panicgrass (Panicum antidotale Retz) plants were grown in a sand culture, subjected to contrasting forms of nitrogen fertilization applied at differing rates and harvested at varying intervals following fertilization. ...
Population dynamics and seasonal history of the boll weevil, Anthonomus grandis Boheman in the semi-arid High and Rolling Plains of Texas
(1969)
The population dynamics and seasonal biological and phenological history of the boll weevil, Anthonomus grandis Boheman was determined for a population inhabiting the High and Rolling Plains of Texas. Seasonal increases ...
An investigation into public post-secondary electronic technology programs in Texas with implications for planning
(1969)
The purpose of this study was to provide information which the Texas Education Agency could use in planning the development of electronic technology programs in junior colleges. The populations included principal employers ...
Metabolic studies on the continuously irradiated rat
(1969)
Male albino rats were continuously irradiated on a 60 R per 20 hour day schedule for 27 days and tested on days 21, 23, 25, and 27. Active transport of U- ¹⁴C glucose was measured using the inverted gut technique. Oxygen ...

(1969)
The Problem [line break] The purpose of this study was to determine the effectiveness of two variations of administering programed instruction materials for teaching selected mechanical drafting concepts as compared to the ...
The transmission of information from school administrators to teachers with particular emphasis on hierarchy of information and channels of communication
(1969)
The purpose of this study was to investigate specified characteristics regarding the flow of information from selected school administrators to selected classroom teachers. The investigation was confined to the downward ...
Excess thermodynamic properties of the binary liquid system 2-butanone-ethylene glycol
(1969)
The excess thermodynamic properties of the binary liquid system, ethylene glycol-2-butanone, have been determined at 25°C. The excess Gibbs free energy has a maximum value of 329 cal. mole⁻¹ at 0.525 mole fraction of ketone. ...
