This paper studies a general p-contractive condition of self-mapping T on X, where X ,d is either metric space or dislocated space, which combines the contribution to upper-bound dTx , Ty, x and y are arbitrary elements in weighted combination distances dx,y dx,Tx,dy,Ty,dx,Ty,dy,Tx, dx,Tx−dy,Ty dx,Ty−dy,Tx.

Certa in propert ies of a hemolysin associated with mumps virus have been described in a previous repor t (1). The labile na ture of this hemolyt ic principle was indicated b y its inact iva t ion b y hea t and b y its deter iorat ion during storage under a va r ie ty of conditons. In order to faci l i tate fur ther invest igat ion of this v i ra l hemolysin, i t was necessary to determine the ...

Abstract In this paper, we investigate the conditions on control mappings $\psi ,\varphi :(0,\infty )\rightarrow \mathbb{R}$ ? , ? : ( 0 ? ) ? R that guarant...

This article concerns boundary-value problems of first-order nonlinear impulsive integro-differential equations: y′(t) + a(t)y(t) = f(t, y(t), (Ty)(t), (Sy)(t)), t ∈ J0, ∆y(tk) = Ik(y(tk)), k = 1, 2, . . . , p,

This paper presents a TEX-based way to localize LATEX documents for natural languages with a script based on the Arabic alphabet. So, native speakers of such natural languages who do not know English can use and understand LATEX.

A new assay has been developed for detection of butyrylcholinesterase (EC 3.1.1.8) activity based upon the change in absorbance of phenol red, caused by the r e l ease of bu ty r i c acid from the substrate. Using c o m m e r c i a l l y avai lable enzyme prepared from horse serum, linear, dose-related decreases in absorbance were obtained, generally with correlation values of 0.965 or greater....

A PVC-membrane ion-selective electrode was constructed for quantitative monitoring of gadolinium(III) ion based on 3-methyl-1H-1,2,4-triazole-5-ylhydrosufide (MTY) as an ion carrier. The electrode performance includes a Nernstian slope of 19.8 ± 0.4 mV per decade across a wide concentration range between 1.0 × 10 and 1.0 × 10 M and a detection limit of 7.3 × 10 M. The best performance was obtai...
