to determine the coefficients of c1 and c in mitscherlich-bray equation, critical level and fertilizer recommendation for potassium (k) as by mitscherlich-bray (mb) equation, an experiment in a randomized complete block design of 5 treatments and 3 replications was carried out in 12 irrigated wheat (triticum aestivum l.) fields in sarpol-e-zohab region during the 2007-08 growing season. the tre...

We present an alternate method to close the master equation representing the continuous time dynamics of interacting Ising spins. The method makes use of the theory of random point processes to derive a master equation for local conditional probabilities. We analytically test our solution studying two known cases, the dynamics of the mean-field ferromagnet and the dynamics of the one-dimensiona...

We study slowly moving solutions of the real Ginzburg-Landau equation on the line, by a method due to J. Carr and R.L. Pego. These are functions taking alternately positive or negative values on large intervals. A consequence of our approach is that we can propose a rigorous derivation of a stochastic model of coarsening by successive elimination of the smallest interval, which was described in...

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...
