The effect of Ag electromigration on the properties of BiPbSrCaCuO superconductors
(Elsevier, 1997)
The effect of an electric field on the diffusion of silver and compounds (Cu and Sr) of BiPbSrCaCuO ceramic superconductors was investigated by energy-dispersive X-ray spectroscopy (EDX). It was established that Ag migrates ...
Construction of a bioraactor for the degradation of the pesticide, aldicarb
(1997)
Water soluble derivatives of cellulose are widely used in various biomedical and biotechnological applications. Sodium carboxymethyl cellulose (25 ml, 1-4% w/v) was insolubilized in the form of microspheres using aluminum ...
Eigenfrequencies of rectangular plate assemblies
(Elsevier Ltd, 1997)
The dynamic stiffness method, which yields exact results for certain class of plate structures, is used to analyse free vibration frequencies of various plate assemblies. The constituent plates of the systems are considered ...
Vibroacoustic testing of linings of clutches
(1997)
The density of a clutch lining is an important parameter for its quality. In this work, a nondestructive vibroacoustic test is studied for evaluating the quality of linings. First, the mechanics of the test is studied. The ...
Catalase adsorption onto cibacron blue F3GA and Fe(III)derivatized poly(hydroxyethyl methacrylate) membranes and application to a continuous system
(Elsevier Science Bv, 1997)
Poly(2-hydroxyethyl methacrylate) (poly(HEMA)) membranes were prepared by W-initiated photopolymerization of HEMA in the presence of an initiator (a-a'-azobisisobutyronitrile, AIBN). An affinity dye, i.e. Cibacron Blue ...
Graft copolymerization of n-vinyl-2-pyrrolidone on dimethyl sulfoxide pretreated poly(ethylene terephthalate) films using azobisisobutyronitrile initiator
(John Wiley & Sons Inc, 1997)
Poly(ethylene terephthalate) (PET) films were grafted with n-vinyl-2-pyrrolidone (n-VP) using an azobisisobutyronitrile (AIBN) initiator. Films were pretreated in dimethyl sulfoxide (DMSO) for 1 h at 140 degrees C before ...
Comparison of β-galactosidase immobilization by entrapment in and adsorption on poly(2-hydroxyethylmethacrylate) membranes
(John Wiley & Sons Ltd, 1997)
beta-Galactosidase was immobilized in/on poly(2-hydroxyethyl methacrylate) (pHEMA) membranes by two different methods: adsorption on Cibacron F3GA derivatized pHEMA membranes (pHEMA-CB), and entrapment in the bulk of the ...
A numerical study of laminar heat convection in ducts of irregular cross-sections
(Pergamon-Elsevier Science Ltd, 1997)
Forced convective heat transfer during hydrodynamically fully developed laminar fluid flow inside ducts of irregular cross section is analyzed utilizing numerical methods. The elliptic grid generation technique is used to ...
Molecular-dynamics simulation of the structural stability, energetics, and melting of Cu-n(n=13-135) clusters
(Springer, 1997)
Cluster properties of copper have been investigated using the Molecular-Dynamics MD technique. The structural stability and energetics of spherical Cu, (n = 13 - 135) clusters have been investigated at temperatures T = 1 ...
Some families of multivalently analytic functions with negative coefficients
(Academic Press Inc Jnl-Comp Subscriptions, 1997)
The authors introduce and study three novel subclasses of analytic and p-valent functions with negative coefficients. In addition to finding a necessary and sufficient condition for a function to belong to each of these ...
