DETERMINATION OF THERMAL GELATION POINTS OF A VINYLIDENE-CHLORIDE ACRYLONITRILE COPOLYMER BY A SPECTROPHOTOMETRIC TECHNIQUE
(ELSEVIER SCI LTD, 1991)
In this study, the thermal gelation points of a vinylidene chloride/acrylonitrile random copolymer have been determined using a spectrophotometric technique. In the first part, the thermal gelation temperature and the ...
Trace formula for the Sturm-Liouville operator with singularity
(VSP BV-C/O BRILL ACAD PUBL, 1998)
Let mu(1), mu(2),..., mu(n),... be the Dirichlet spectrum of the operator -d(2)/dx(2) + q(x) acting on L-2(0,pi). In the special case where q(x) = 0, mu(n) = n(2). In the [1] and others discovered the asymptotic formula ...
In vitro swelling studies and preliminary biocompatibility evaluation of acrylamide-based hydrogels
(ELSEVIER SCI LTD, 1996)
In this in vitro study, the biocompatibility of acrylamide-based hydrogels such as acrylamide/crotonic and acrylamide/itaconic acid, prepared by using gamma-rays, has been investigated against some biochemical parameters ...
