An experimental investigation of factors affecting acoustic wave velocities in sandstone
(1969)
In recent years much energy has been directed toward obtaining equations for predicting physical properties of subsurface formations from indirect measurements. One of the most important examples is in the use of the sonic ...
Unrestricted Hartree-Fock atomic wave-functions
(1969)
Unrestricted Hartree-Fock (UHF) wavefunctions, in the Spin-Polarized Hartree-Fock (SPHF) approximation, have been determined for a number of neutral, divalent, and trivalent transition metal atoms with d[superscript n] ...
Preservation of bovine sperm at variable temperatures
(1969)
The effects of extenders, and variable temperatures on progressive motility of bovine spermatozoa were investigated in a series of experiments. Semen obtained from Hereford bulls was extended with Standard Cornell University ...
An experimental comparison of 16 mm sound animated films and conventional lecture-demonstration methods of teaching selected units in engineering graphics
(1969)
The research was designed to determine the relative effectiveness of 16 mm sound animated films compared to the conventional lecture-demonstration method of teaching selected units in engineering graphics. The two methods ...
