Studies of the amidase activity ofextracts of various animal tissues have been reported in earlier papers (Bray, James, Ryman & Thorpe, 1948; Bray, James, Raffan, Ryman & Thorpe, 1949a; Bray, Thorpe & Wood, 1949c; Bray, James, Thorpe, Wasdell & Wood, 1949 b). The present paper records further observations, including the behaviour of the enzyme towards some saturated long-chain and w-phenylsubst...

It was stated in previous papers (Avis, Bergel & Bray, 1955; Avis, Bergel, Bray, James & Shooter, 1956; Avis, Bergel & Bray, 1956) that the enzymie activity of purified xanthine oxidase from cow's milk, like that of other enzymes, deteriorates in aqueous solution under a variety ofmild conditions. Since then we recorded in a preliminary communication (Bergel & Bray, 1956) the stabilizing effect...

abstract in this study, p critical level for corn plant (zea mays l.) was determined using pbc in 25 combined soils samples from different fields of east azerbaijan province. to calculate the pbc, current soil p test methods such olsen,colwel, soltanpur and schowab, kelna2 and iron impregnated strips as a quantity factor (q) and the methods of soluble p measurements such as distilled water, cal...

−N-succinyl-chitosan-g-polyacrylamide/attapulgite (NSC-g-PAM/APT) composite was applied as adsorbent for the removal of methylene blue (MB) from aqueous solution. The initial pH value of the dye solutions, the contact temperature, the contact time and the concentration of the dye solutions on adsorption capacity of the composite for MB dye were investigated. The adsorption kinetics and isotherm...

The development and motion of fronts associated with lee-side troughs on large mountain barriers has been investigated. These fronts differ from ordinary cold fronts in their horizontal temperature field, which is characterized by a sinusoidal thermal ridge. The thermal ridge intensifies, while remaining stationary with respect to the mountains, and moves eastward upon the approach of a Pacific...

We use the replica method in order to obtain an expression for the variational free energy of an Ising ferromagnet on a dilute Viana-Bray lattice in the presence of random external fields. Introducing a global order parameter, in the replica-symmetric context, the problem is reduced to the analysis of the solutions of a non linear integral equation. At zero temperature, and under some restricti...
