The impact of Title One, Elementary and Secondary Education Act of 1965, on the Lufkin Independent School District
(1969)
The objective of this research was to evaluate activities implemented under Title One, Elementary and Secondary Education Act of 1965, Public Law 89-10, as they affected the academic achievement of pupils in the Lufkin ...
Network planning based on the gamma distribution
(1969)
The primary objective of this research is to develop a different method of analyzing network-based planning models. This method of analysis is activity oriented and incorporates the entire distribution of activity completion ...
Contributions to the stability of variance estimators and the regression estimator
(1969)
In stratified sampling when only one unit is selected from each stratum, the estimation of variance by customary methods becomes impossible. Various attempts have been made to solve this problem. It has been shown in this ...
Distribution and seasonal fluctuations in abundance of benthic fauna in a Texas artificial pond in relation to selected environmental factors
(1969)
The results of a 12-month study of benthic fauna in Postoak Lake, Range and Forestry Area, Texas A&M University, are presented. The lake has a surface area of approximately 1.87 acres and a maximum depth of 11.5 feet. ...
Human factors in the moving merge process
(1969)
The objective of this research was to investigate the importance of some independent environmental variables in the moving merge process utilizing human factors as indices of driver comfort in such a dynamic situation. The ...
A gas chromatographic investigation of secondary alcohol and ketone utilization by aerobic microorganisms
(1969)
Low molecular weight aliphatic alcohols and ketones represent a major class of synthetic chemicals and find extensive use as commercial solvents. Their occasional appearance in certain types of industrial waste effluents ...
Synthesis of aminophosphonic acids containing carboxyl groups
(1969)
In this research three new aminophosphonic acids containing carboxyl group have been synthesized and characterized. The amino acids are: aminophosphonoacetic acid, 4-amino-phosphonobutyric acid, and 5-amino-5-phosphonopentanonic ...
A restricted Runge-Kutta method
(1969)
Consider the differential system dy[subscript r]/dx = f[subscript r](x, y₁, y₂, ..., y[subscript m]), y[subscript r](x₀) = r[subscript r0] (r = 1, 2, ..., m). The Runge-Kutte method applies to all functions f[subscript ...
Magnetic circular dichroism studies
(1969)
The MCD spectra of the negative ions of magnesium phthalocyanine and the mononegative ion of coreonene have been measured and used with theoretical calculations to assign several of the bands. Self-consistent field wave ...
On certain classes of near-rings
(1969)
Three special classes of near-rings are studied in this dissertation: near-fields, distributively generated near-rings, and near-rings with zero divisors. Chapter I contains introductory material. In Chapter II various ...
