Nicotine-induced eeg and behavioral arousal,
(Elsevier, 1965-11)
(-) Nicotine, in doses of 0.005-0.01 mg/kg given intravenously over 1 min, produced transient behavioral arousal and EEG activation in cats with chronic indwelling brain electrodes. The effects of nicotine were evident ...
Behavioral variables affecting the development of amphetamine tolerance
(Springer-Verlag, 1966-01)
The behavioral effects of chronic administration of d-amphetamine in rats at a dosage of 1 mg/kg were studied with baselines involving either food or shock reinforcement. Food reinforcement was assigned according to a fixed ...
Neuronal mechanisms of ketamine-induced anesthesia
(Elsevier, 1968-11)
The sites of action of ketamine (CI-581; 2-(0-chlorophenyl)-2-methylamino cyclohexamine HCl) were determined in the central nervous system using electrophysiological techniques in both acute and chronic cat experiments. ...
Some measurements of the infrared spectral radiances and emissivities of hydrogen fluoride in combustion gases at 1000[deg]C
(Elsevier, 1964)
Spectral radiances and emissivities were determined from moderate-resolution emission and absorption measurements in the exhaust gases of a small rocket motor. Data was obtained in the 2 to 3 [mu] region for ClF3-NH3 ...
A comparison of the properties of two forms of tyrosinase from Neurospora crassa
(Elsevier, 1961-12)
The differences between a thermostable (T) and thermolabile (T) form of tyrosmase from Neurospora crassa have been studied by means of a spectrophotometric technique using ascorbate or ferrocyanide. No significant differences ...
Protein---carbohydrate interaction : Part XXI. The interaction of concanavalin a with d-fructans
(Elsevier, 1969-06)
The immunochemical techniques of quantitative precipitation and hapten inhibition have been employed in a study of the interaction of concanavalin A with several levans of bacterial and plant origin. Of the polysaccharides ...
The photometric estimation of luciferase in luminous bacterial cells
(Elsevier, 1963-05)
The bacterial luciferase reaction carried out in vitro can be used as a basis for a semiquantitative assay of active luciferase in bacterial cells. Relations between maximum luminous intensity generated and the amount of ...
