Volatile combustion products of polycarbonate and polysulfone
(Wiley Subscription Services, Inc., A Wiley Company, 1972-04)
Thermal analysis of polycarbonate and polysulfone has shown each plastic to undergo a two-step decomposition, the first step involving production of high-boiling chain scission and volatile products, the second resulting, ...
The effects of chlorpromazine on psychomotor stimulant self-administration in the Rhesus monkey
(Springer-Verlag, 1972-06)
The effects of acute and chronic chlorpromazine treatment on psychomotor stimulant self-administration behavior in the Rhesus monkey were determined. Chlorpromazine treatment significantly increased the frequency of ...
Sedimentation behavior of solubilized gonadotropin receptor from plasma membranes of bovine corpus luteum
(Elsevier, 1976-03-25)
The gonadotropin receptors associated with plasma membrane fractions were solubilized by detergents, including Triton X-100, Lubrol WX, Lubrol PX and sodium deoxycholate before and after equilibration with 125I-labelled ...
Effect of photic stimulation on acetylcholine release from cat cerebral cortex
(Elsevier, 1972-01)
Cortical release of acetylcholine was assayed using the leech muscle preparation in cats with transected brainstems. Both spontaneous and elicited somatosensory and visual cortical release of acetylcholine were measured, ...
Studies on the kinetics and mechanism of reduction of flavodoxin from Peptostreptococcus elsdenii by sodium dithionite
(Elsevier, 1973-07-05)
1. 1. The reactions of the oxidised and semiquinone forms of Peptostreptococcus elsdenii flavodoxin with sodium dithionite have been studied by stopped flow spectrophotometry. At low ionic strength where comproportionation ...
Entropy and heat capacity of europium(III) bromide from 5 to 340 K
(Elsevier, 1975-07)
The heat capacity of a polycrystalline sample of EuBr3 has been measured from 5 to 340 K and found to be without transitions in this region. Values of the thermodynamic functions Cp(T), {So(T) - So(5 K)}, and {Ho(T) - Ho(5 ...
Si-Al ordering in nephelines
(Springer-Verlag, 1971-06)
Different degrees of Si-Al ordering are demonstrated to exist in nepheline on the basis of five crystal structure refinements on specimens with different geologic origins and laboratory treatments. Disorder increases in ...
Synthesis of metabolism-resistant substrates for the transport system for cationic amino acids; their stimulation of the release of insulin and glucagon, and of the urinary loss of amino acids related to cystinuria
(Elsevier, 1973-04-16)
Several amino acids have been synthesized as model transport substrates building on the piperidine and cyclohexane rings. Only when the distal N atom is part of an unambiguously cationic structure are these compounds ...
