Aim To study the role of vaginal hysterectomy in non-descent uterus and to compare it with abdominal hysterectomy with respect to operative time, intraoperative blood loss and complications, ambulation, and postoperative complications. Materials and methods A prospective non-randomized study was carried out on 200 cases at a rural tertiary care center in B.G.

Multivariate regression calibration using multiple linear regression (MLR), principle component regression (PCR) and partial least squares regression (PLSR) algorithm was performed on Pu, Pu, Pu and Pu atom% abundances to predict Pu isotopic abundance. The MLR algorithm was found to be the best among these three algorithms. The effect of Pu composition on the Pu abundance prediction was found to be small but significant especially for achieving high accuracy of <0.

Industrial waste is one of the main causes of environmental pollution. Laser-induced breakdown spectroscopy (LIBS) was applied to detect the toxic metals in the sludge of industrial waste water. Sludge on filter paper was obtained after filtering the collected waste water samples from different sections of a water treatment plant situated in an industrial area of Kanpur City.

Different correlations are evaluated for the determination of (242)Pu in Pu generated from PHWR reactors with an average burn-up of about 10,000 MWd/TU. It is shown that the correlations involving ratios of Pu isotopes, except for (241)Pu, provide data with better confidence compared with those involving the atom% abundance. These correlations are also attractive when the decay period of the given sample is not known.

Laser-induced breakdown spectroscopy (LIBS) has been developed for determining the percentage of uranium in thorium-uranium mixed oxide fuel samples required as a part of the chemical quality assurance of fuel materials. The experimental parameters were optimized using mixed oxide pellets prepared from 1:1 (w/w) mixture of thorium-uranium mixed oxide standards and using boric acid as a binder. Calibration curves were established using U(II) 263.
