Molecular structures by theoretical means : applications to metal ion monohydrates, quadruply bonded dichromium(II) complexes, and carbonyl labilization in ligand substitution reactions
(1988)
Ab initio Hartree-Fock-Roothaan self-consistent-field (HFR-SCF) and generalized valence bond (GVB) geometry optimizations are used to study problems that are inaccessible to experiment. The theoretically determined molecular ...
A parametric digital signal processing algorithm for arcing high impedance fault detection
(1988)
There is a problem which currently exists in the electric utility industry with the detection of high impedance faults. A high impedance fault is one which does not draw sufficient fault current to be detected and cleared ...
The oxidative dehydrogenation of ethane : gas-phase and catalytic
(1988)
The gas-phase and the catalytic oxidative dehydrogenation of ethane were studied. Lithium-promoted magnesium oxide was investigated as the catalyst. In the gas-phase oxidation study a perfectly mixed tubular reactor was ...
The effects of autocratic and democratic methods of teaching on competitive and cooperative learning modes in higher education
(1988)
This study was designed to further understanding about the intersecting of autocratic and democratic methods of teaching with competitive and cooperative modes of learning in higher education. The investigation was interested ...
Pigmentation potency of turf Bermuda grass with analysis of carotenoids in egg yolks
(1988)
Four experiments were performed to evaluate the potential of using turf Bermuda grass as a pigmenting agent for laying hens. In experiment 1, the carotene and xanthophyll changes during growth of turf Bermuda grass (Cynodon ...
Market organization and product quality under asymmetric information : a comparison of monopoly and competitive market
(1988)
A comparison of product qualities across different market structures has been a major issue in the economic analysis of quality determination. The literature focused in particular on the difference in product quality between ...
A comparison of three conservative treatments on the myofascial component of college-aged temporomandibular joint syndrome patients
(1988)
The purpose of this study was to examine the effects of exercise, biofeedback, and placebo on the masseter tension level and the related pain of temporomandibular joint dysfunction syndrome. Fifteen Texas A&M University ...
Perceptions of secondary agricultural science teachers toward proposed changes in agricultural curricula in Texas
(1988)
This study concerned the changes in curricula taking place in agricultural science in Texas. Teachers were being directed to change from a "traditional" production agriculture based, full-year curriculum, to one more science ...
The solubility of calcite in NaC1 and Na-Ca-C1 brines
(1988)
Calcite solubility was determined experimentally in NaCl solutions from 25° to 89°C and in Na-Ca-Cl solutions at 25°C. The results are important for understanding the subsurface diagenesis of calcite cements. Solution ...
