Application of the H-N method to the critical slab problem for reflecting boundary conditions
(Pergamon-Elsevier Science Ltd, 2004)
The recently developed H-N method is used to solve the critical slab problem for a slab which is surrounded by a reflector. In the special case: for R = 0 (the reflection coefficient) the problem reduces to the one under ...
Investigation of the (n, 2n) reaction cross sections of some neighbouring nuclei with and without deformation
(Indian Assoc Cultivation Science, 2004)
The (n, 2n) reaction cross section calculations for some neighbouring target nuclei either with deformation or without deformation have been made for an incident energy range of 8 - 24 MeV. In these calculations, the ...
Subspaces of A-statistically convergent sequences
(Akademiai Kiado, 2003)
Let A be a nonnegative regular summability method. In this paper we deal with various subspaces of A-statistically convergent sequences by using the rate of convergence concept. We show, under certain conditions, that these ...
Vickers microhardness studies of Fe-Mn binary alloys
(Elsevier Science Bv, 2004)
The room temperature microhardness of Fe-Mn binary alloys with different compositions was measured using a Vickers microhardness tester in the applied load ranging from 0.245 to 4.9 N. A significant indentation size effect ...
Microstructural, thermal, and electrical properties of Bi1.7V0.3Sr2Ca2Ca3Ox glass-ceramic superconductor
(Wiley-V C H Verlag Gmbh, 2004)
A glass-ceramic Bi1.7V0.3Sr2Ca2Cu3Ox superconductor was prepared by the melt-quenching method. The compound was characterized by scanning electron microscopy, x-ray diffraction, differential thermal analysis, current-voltage ...
Preparation and application of spacer-arm-attached poly (hydroxyethyl methacrylate-co-glycidyl methacrylate) films for urease immobilisation
(Elsevier Science Bv, 2003)
Immobilisation of urease onto plain and six-carbon spacer-arm (i.e. 1,6-diaminohexane) attached poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) [poly (HEMA-GMA)] films was studied. The epoxy groups containing ...
A Three Dimensional Lead(II) Polymer with Bridging Saccharinate and Unusually Coordinated Acetate Ligands Synthesis, IR Spectra, and Crystal Structure of [Pb(H2O)(µ-OAc)(µ-sac)]n
(Wiley-V C H Verlag Gmbh, 2003)
The complex [Pb(H2O)(mu-OAc)(mu-sac)]n with acetate (OAc) and saccharinate (sac) ligands was characterized by IR, elemental analysis and X-ray crystallography The mixed-anion lead(II) complex crystallizes in the triclinic ...
Permeation and separation characteristics of acetic acid/water mixtures through poly(vinyl alcohol-g-itaconic acid) membranes by pervaporation, evapomeation, and temperature-difference evapomeation
(Wiley, 2004)
In this study, itaconic acid (IA) was grafted onto poly(vinyl alcohol) (PVA) with cerium(IV) ammonium nitrate as an initiator at 45degreesC. The grafted PVA was characterized with Fourier transform infrared spectroscopy, ...
Fluoride release from microporous poly(2-hydroxyethyl methacrylate) membranes
(Elsevier Science Bv, 2003)
Fluoride ion is commonly used in the preventive treatment of tooth decay and when provided with extra fluoride, children living in regions that lack fluoride benefit from it. In the present study, the clinical properties ...
