Department of Chemistry, University of Kalyani. Kalyani-741 235 <em>Manuscript received 21 September 1993, revised 6 April 1994, accepted 29 April 1994</em> Viscosity B-coefficients of a number of drugs, viz. hydrochlorides of promethazine, chlorpromazine, papaverine, ephedrine, pseudoephedrine and isoxsuprine, in water have been determined, and found to be fairly high. The solvation numbers, single ion viscosity B-coefficients (B<sub>+</sub>) show that the cations of promethazine, chlorpromazine and papaverine are highly solvated due to hydrophobic hydrations whereas other cations are re

Abstract:

Let Ω_0^r be a class of holomorphic functions ω in the unit disk ∆, with real coefficients, and such that |ω(z)|<1, ω(0)=0, z∈∆. The coefficients problem in the class Ω_0^r is formulated as follows: find the necessary and sufficient conditions to be imposed on the real numbers {ω}_1,{ω}_2,… in order for the series {ω}_1 z+{ω}_2 z^2+⋯ to be the Taylor series of a function in the class Ω_0^r. The class B^r consists of holomorphic functions f in ∆ with real coefficients and such that 0<|f(z)|≤1, z∈∆. The classes B_t^r, t≥0, are defined as the sets of functions f∈B^r such that f(0)=e^(-t).

Measures of demand elasticity indicate the direction and intensity of the reaction of the quantity of demand for a good or service due to a change in the determinants of demand. Among them, the price elasticity of demand stands out because it measures the reaction of customers to price changes. Price elasticity is therefore important for management in making pricing decisions because it answers the question of how raising or lowering prices will affect sales revenue and, consequently, the company's financial results. In this paper, the elasticity of demand for selected types of bread from the

Abstract:

Abstract Wavelet transform algorithms (Mallat’s algorithm, `a trous algorithm) require input data in the form of a sequence of numbers equal to the signal projection coefficients on a space spanned by integer-translated copies of a scaling function. After sampling of the continuous-time signal, it is most frequently possible to compute only approximated values of the signal projection coefficients by choosing a specific signal approximation. Calculation of the signal projection coefficients based on the signal interpolation by means of cubic B-splines is proposed in the paper.

The new construction is based on the factorization of wavelet transforms into lifting steps. The second and third contributions are new insights on how to use these and other wavelets in statistical applications. The second contribution is related to the bias of a wavelet representation.

The study the Abel differential equation x ′ = A ( t ) x 3 + B ( t ) x 2 + C ( t ) x . Specifically, we find bounds on the number of its rational solutions when A ( t ) , B ( t ) and C ( t ) are polynomials with real or complex coefficients; and on the number of rational limit cycles when A ( t ) , B ( t ) and C ( t ) are trigonometric polynomials with real coefficients.

Abstract:

Assuming that the corrections to relevant Wilson coefficients from new physics (NP) contain the possible CP phases, we analyze the constraints on the NP corrections from the updated experimental data on rare B decays from LHCb, BABAR, and BELLE, etc. systematically. Through global fit among the theoretical evaluations and corresponding experimental observations, we find that the possible CP phases of the corrections to relevant Wilson coefficients from NP affect the allowed parameter space obviously.

Abstract:

Using the most general effective Hamiltonian comprising scalar, vector and tensor type interactions, we have computed the branching ratio, the forward–backward (FB) asymmetry and the normalized FB asymmetry as functions of the new Wilson coefficients. It is found that the branching ratio depends on all new coefficients, but the asymmetries can be analyzed in terms of only one Wilson coefficient.

We introduce the subclass $T^*(A,B,n,a)$ ($-1 \le A < B\le 1$, $0 < B \le 1$, $n \ge 0$, and $0\le\alpha <1$) of analytic func;tions with negative coefficients by the operator $D^n$. Coefficient estimates, distortion theorems, closure theorems and radii of close-to-convexety, starlikeness and convexity for the class $T^*(A,B,n,a)$ are determined. We also prove results involving the modified Hadamard product of two functions associated with the class $T^*(A,B,n,a)$. Also we obtain Several interesting distortion theorems for certain fractional operators .of functions in the class $T^*(A

Abstract:

A new method of partitioning the viscosity B coefficients has been proposed on the basis of the assumption that ionic B values should be a monotonie function of crystal radii cubed, independent of the sign of the charge, for aqueous and various non-aqueous systems. Ionic B values thus obtained in different solvents by a single method of division provide a basis for uniform comparison among themselves as well as with the existing values. The usual assumption of equal contributions of K+ and Cl− ions has been discarded. The internal consistency of the derived set of Bi values is demonstrated by

Abstract:

The objective was to parameterize a modified water cloud model using crop coefficients (A and B). These crop coefficients were derived from Landsat-8 and Sentinel-2 data. Whereas the coefficients C and D are of soil parameters. The water cloud model was modified using crop coefficients by minimizing the RMSE between observed VVσ0 and Sentinel-1 based simulated VVσ0. The comparison with observed and simulated VV polarized σ0 showed low RMSE (0.81 dB) and strong R2 of 0.98 for NDVI-EVI combination. However, based on other possible combinations of vegetation indices VVσ0 and simulated VVσ0 do not

Abstract:

An experimental study was carried out to find a way of using sponge cubes as a biomass support medium to reaction tanks for nitrified liquor recycling process. Type-A, in which biomass fixed cubes are contacted with both anoxic and oxic stages and Type-B, where biomass fixed cubes are contacted with either anoxic or oxic stages, were selected as experimental cases. The results showed that the amount of CO2-C generated which was related to sludge production for Type-B exceeded the amount for Type-A by between 12 to 21%. The nitrification and denitrification rate coefficients at 20°C in Type-A w

And a refined diffusion model which considered the time dependent apparent diffusion coefficients and time dependent surface chloride concentration was established. It was found that both apparent diffusion coefficients and surface chloride concentration are time dependent and both are significantly influenced by water to binder ratio. Apparent diffusion decrease with time while surface chloride concentration increase with time. but water to binder rati

Let a={am} and b={bm} be two periodic sequences of complex numbers, and, additionally, a is multiplicative. In this paper, the joint approximation of a pair of analytic functions by shifts (ζnT(s+iτ;a),ζnT(s+iτ,α;b)) of absolutely convergent Dirichlet series ζnT(s;a) and ζnT(s,α;b) involving the sequences a and b is considered. Here, nT→∞ and nT≪T2 as T→∞. The coefficients of these series tend to am and bm, respectively. It is proved that the set of the above shifts in the interval [0,T] has a positive density. This generalizes and extends the Mishou joint universality theorem for the Riemann

Fluid mechanics is seen as the study on the underlying mechanisms of liquids, gases and plasmas, and the forces on them. In this paper, we investigate a (2 + 1)-dimensional generalized nonlinear system in fluid mechanics and plasma physics. By virtue of the Pfaffian technique, the Nth-order Pfaffian solutions are derived and proved, where N is a positive integer. Based on the Nth-order Pfaffian solutions, the first- and second-order breather solutions are obtained. In addition, Y-type and X-type breather solutions are constructed. Furthermore, we investigate the influence of the coefficients i
