Experiments were undertaken to study the relationship between the drying constant and the shrinkage constant of food products during drying. Three particular geometrical shapes of parallelepiped, cylindrical and spheres were selected from potatoes (aspect ratio = 1:1, 2:1, 3:1), cut beans (length: diameter = 1:1, 2:1, 3:1) and peas, respectively. The volumetric shrinkage behaviour and drying be...

 In network code setting, a constant dimension code is a set of k-dimensional subspaces of F nq . If F_q n is a nondegenerated symlectic vector space with bilinear form f, an isotropic subspace U of F n q is a subspace that for all x, y ∈ U, f(x, y) = 0. We introduce isotropic subspace codes simply as a set of isotropic subspaces and show how the isotropic property use in decoding process, then...

We define the generalized-Euler-constant function γ(z) = ∑∞ n=1 z n−1 ( 1 n − log n+1 n ) when |z| ≤ 1. Its values include both Euler’s constant γ = γ(1) and the “alternating Euler constant” log 4 π = γ(−1). We extend Euler’s two zeta-function series for γ to polylogarithm series for γ(z). Integrals for γ(z) provide its analytic continuation to C − [1,∞). We prove several other formulas for γ(z...

The kinetics of Osmium(VIII) (Os(VIII)) catalysed oxidation of diclofenac sodium (DFS) by diperiodatoargentate(III) (DPA) in alkaline medium at a constant ionic strength of 0.60 mol dm -3 has been studied spectrophotometrically. The stoichiometry was found to be 1:1 i.e, one mole of DFS reacted with one mole of DPA. The reaction was first order with respect to [DPA] and [Os(VIII)], less than un...

We consider separation of ideal multicomponent mixtures with constant relative volatilities and constant molar flows and at constant pressure. The exact analytical solution of minimum energy in a generalized Petlyuk arrangement for separation of N-component feed into M products has been derived. Interestingly, the minimum-energy solution in a complex integrated Petlyuk arrangement is equal to t...
