An experimental and mathematical study of in situ combustion in a segregated system
(1968)
Some of the field pilot studies made to date have indicated that forward combustion proceeds in a segregated manner in oil reservoirs and that surfaces at which combustion is occurring develop both parallel and perpendicular ...
Electron paramagnetic resonance studies of valence tautomer anion radicals and ion-pairing in semiquinones
(1968)
The epr spectral parameters of the monohomocyclooctatetraene anion radical (XXXV) have been found to be relatively insensitive to changes in solvent, temperature, and counterion. The similar geometry of the anion radical, ...
The phyllostomid bats of the genus Carollia Gray
(1968)
The genus Carollia of the family Phyllostomidae is found to comsist of at least four species. These are C. perspicillata (Linnaeus), C. brevicauda (Wied), C. subrufa (Hahn), and C. castanes H. Allen. C. brevicauda has not ...
Estimating a population of pink shrimp by the use of catch per effort and tagging data
(1968)
A study of some methods used to obtain information on the dynamics of the Tortugas pink shrimp (penaeus duorarua) fishery in south Florida is given. Tagging experiments were used together with catch and effort data to find ...
Effect of two learning treatments on the cognition of elementary students
(1968)
Purpose: This study compared the cognition of sixth grade students (by sex) exposed to two different learning treatments (male voice in conjunction with projected visuals versus female voice in conjunction with identical ...
Radiation transfer through the earth's atmosphere using the matrix operator method
(1968)
The matrix operator method of solving radiation transfer problems is extended to include polarization. The reflection and transmission operators are presented with continuous variables. An explicit expression for the phase ...
The President's Scholars Award Program at Texas A & M University
(1968)
The primary purpose of this study was to determine if the President's Scholars Award Program at Texas A&M University has been successful in enrolling high academic achievers who differ significantly in selected nonintellectual ...
The impact of social change on the Lutheran elementary parochial school in Texas
(1968)
The first specific objective of this study was to determine the significant differences in the attitudes of Texas rural Lutheran elementary parochial school pupils, rural parents, and rural older adults when compared with ...
A hydrodynamic study of flow in irrigation furrows
(1968)
Equations of motion describing flow in irrigation furrows are derived and presented in characteristic form. An estimate of furrow roughness is obtained from field data. A procedure for determining infiltration rates from ...
