    Notes: Abstract: By analysis of fission product γ-ray data measured at Eurogam II using a 248Cm source, yrast levels up to about 2 MeV in the N=84 three-particle nucleus 135Sb have been identified. These levels are interpreted as π g7/2ν f7/2 2 and π g7/2ν f7/2h9/2 states with the help of shell model calculations using empirical nucleon-nucleon interactions.

    Estimation of sulfur in coal by fast neutron activation (1995)

    Notes: Abstract A simple method is described for estimation of sulfur in coal using fast neutron activation of sulfur, i.e.32S(n,p)32P and subsequent measurement of32P β-activity (1.72 MeV) by a Geiger-Müller counter. Since the sulfur content of Indian coal ranges from 0.25 to 3%, simulated samples of coal containing sulfur in the range from 0.25 to 3% and common impurities like oxides of aluminium, calcium, iron and silicon have been used to establish the method.

    Theoretical study of the flow field inside a hydrocyclone with vortex finder diameter greater than that of apex opening—I. Laminar case (1980)

    Notes: Abstract The axi-symmetric laminar boundary layers, formed on the conical surface and under the cyclone roof, have been calculated by Pohlhausen's method assuming that the tangential velocity outside boundary layers varies as r −n up to the point where boundary layers meet solid body rotating liquid column and thereafter as r—as found in experiments—where r is the distance from the axis of the cone and n is flow pattern constant. Point of interaction of the boundary layers with solid body rotating liquid column has been taken from experimental results obtained with a hydrocyclone having vortex finder diameter greater than that of apex opening. Results show that there is no possibility of separation of boundary layers from cyclone wall.

    Notes: Abstract As in the laminar case (see previous paper), the axi-symmetric turbulent boundary layers have been studied inside a hydrocyclone having overflow diameter greater than that of underflow. This type of hydrocyclone is generally used in practical applications. Calculating total flux through the boundary layers, formed on the conical surface and under the roof of the hydrocyclone, a mathematical model of the flow field has been obtained which agrees very well with previous experimental findings.

    ON A MIXED-HYBRID FINITE ELEMENT METHOD FOR ANISOTROPIC PLATE BENDING PROBLEMS (1996)
    Chichester [u.a.] : Wiley-Blackwell
    International Journal for Numerical Methods in Engineering 39 (1996), S. 4063-4089

    ISSN: 0029-5981
    Keywords: anisotropic plates ; mixed-hybrid finite element method ; Engineering ; Engineering General

    Topics: Mathematics , Technology
    Notes: The paper deals with a new mixed-hybrid finite element method for anisotropic elastic plate bending problems, which gives a simultaneous approximation to bending and twisting moment tensor and deflection fields in the interior of each triangle and traces of the displacement field and its normal derivative on sides of each triangle. Efficient computer implementation procedures for this mixed-hybrid scheme have been developed. Results of numerical experiments on different anisotropic plates of practical and research interest are given.

    Kinetics of the oxidation of U (IV) by hydrogen peroxide in sulfuric acid medium (1981)
    New York, NY : Wiley-Blackwell
    International Journal of Chemical Kinetics 13 (1981), S. 385-401 
    Details
    ISSN: 0538-8066
    Keywords: Chemistry ; Physical Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The kinetics of the reaction have been investigated in H2SO4 medium under different conditions. The observed bimolecular rate constant kobs, has been found to depend on [H+]-0.55 and to increase with the initial concentration ratio of the reactants R0 = [H2O2]0/[U (IV)]0 above 0.49. The activation energy of the overall reaction has been determined as 13.79 and 14.3 kcal/mol at R0 = 1 and 0.35, respectively. Consistent with experimental data, a detailed reaction mechanism has been proposed where the hydrolytic reaction (4) followed by the rate-controlling reaction (10) and subsequent fast reactions of U (V) and OH radicals are involved: A kinetic expression has been derived from which a graphical evaluation of (kK4)-1 and k-1 has been made at R0 = 1 as (12.30 ± 0.09) × 10-3 M min, (6.23 ± 2.19) × 10-4 M min; and at R0 = 0.35 as (12.63 ± 2.13) × 10-3 M min, (8.32 ± 6.62) × 10-4 M min, respectively. Indications of some participation of a chain reactionat R0 = 1 have been obtained without affecting thesecond-order kinetics as observed.

    Reaction between U(IV) and H2O2 in hydrochloric acid medium (1982)
    New York, NY : Wiley-Blackwell

    Topics: Chemistry and Pharmacology
    Notes: Kinetic investigations on the reaction between U(IV) and H2O2 have been carried out at different acidities in chloride medium at an ionic strength of 2M. The observed bimolecular rate constant has been found to be dependant on [H+]-1.3. The activation energy of the overall reaction has been found to vary from 13.4 ± 0.7 to 18.0 ± 0.8 kcal/mol in the range of acidity from 0.3 to 1.5M. The results have been explained on the basis of three parallel rate-controlling reactions involving unhydrolyzed species of U(IV) and hydrolyzed species UCl(OH)2+ and UO2+. The values of the rate constants for these three reaction paths have been found to be of the order of 3.95, 5.59 × 103, and 1.49 × 105M-1 min-1, respectively.
