Effectiveness factor calculations for immobilized enzyme catalysts
(Wiley Subscription Services, Inc., A Wiley Company, 1973-09)
The steady state, nonlinear diffusion equations which describe reactions in constrained enzyme solutions are of great interest in many biological and engineering applications. As in other types of nonlinear differential ...
Micro method for determination of borohydride with NAD+
(Elsevier, 1973-08)
A spectrophotometric method for the determination of borohydride is described. It involves the reduction of NAD+ to a number of isomeric forms of NADH by borohydride. In the standard assay procedure herewith presented, ...
Experimental and mathematical modeling studies of protozoan predation on bacteria
(Wiley Subscription Services, Inc., A Wiley Company, 1973-07)
The predation of bacteria by protozoan in both continuous and batch cultures was studied using experimental and modeling techniques. The predator organism was the ciliate, Tetrahymena pyriformis. The bacterium, Aerobacter ...
Short-term effects of marijuana smoking on cognitive behavior in experienced male users
(Springer-Verlag, 1973-03)
The effects of smoking marijuana on the ability to use abstract concepts was tested in 12 experienced marijuana users. Each subject was tested three times, after smoking prepared 300 mg cigarettes containing either 0, 1.5 ...
Tolerance to the effects of daily nicotine on rat bar pressing behavior for water reinforcement
(Elsevier, 1973)
The effects of daily nicotine tartrate given IP in a dose of 0.25 mg/kg twice a day for 15 days was studied on bar pressing behavior for water reinforcement in the rat. A modified FR1 5 schedule was used. Nicotine injections ...
Verification of rat brain acetylcholine antidepletion by morphine using gas chromatography

The enthalpies of combustion and formation of [2.2]-paracyclophane and triptycene
(Elsevier, 1973-09)
The enthalpies of combustion, ΔHoc, for crystalline [2.2]-paracyclophane (C16H16) and triptycene (C20H14) have been measured by oxygen combustion calorimetry. The derived standard enthalpies of formation at 298.15 ...
