The relationship of species development, semen physiology and post mortem evaluations to reproduction in the American pen-raised chinchilla
(1969)
A literature review tracing the evolvement of the American pen-raised chinchilla was conducted; it indicated that there have never been three distinct species of chinchillas in the United States, brevicaudata, lanigera and ...
Selection of regression variables and contributions to the estimation of variance components
(1969)
This dissertation consists of two parts. In Chapter I an efficient procedure is described for identifying best regression subsets. In Chapter II the likelihood functions for the random, nested and random, classification ...
Gene action in intervarietal diallel crosses of upland cotton Gossypium hirsutum L
(1969)
A complete diallel cross consisting of all possible F₁ hybrid combinations among 9 selected cotton varieties and their corresponding F₂'s were studied using a split-plot design with four replications. Data were taken on ...
The effects of long-wavelength infrared radiation on the flying activity of stable flies, Stomoxys calcitrans (L.)
(1969)
Stable flies, Stomoxys calcitrans (L.), were exposed to infrared radiation to determine if they respond to such radiation emitted by cattle and other warm-blooded hosts. The infrared radiation was emitted from a spherical ...
Formulation of a model for packed distillation columns on the basis of field tests
(1969)
On the basis of a series of field tests which were made on a packed distillation column located near Refugio, Texas, several possible methods for the modeling of packed distillation columns were investigated. Because of ...
A comparison of two techniques of teaching engineering descriptive geometry
(1965)
Statement of the Problem: The purposes of this research were to determine: (1) the effectiveness of self-scoring as an immediate reinforcement to learning using six selected principles of descriptive geometry, (2) which ...
A study of kinetin in plants
(1965)
Since the discovery of kinetin in 1954, the translocation pattern of this plant growth regulator had remained obscure. On the basis of general observation, it has been assumed that kinetin is largely immobile in plants. ...
