This publication describes a method for the determination of total bisphenol A (BPA and conjugated BPA) following enzyme hydrolysis and is intended as a companion to our previously developed analytical method for the determination of free BPA (the aglycone) in human blood and urine using high-performance liquid chromatography-tandem mass spectrometry ( 1).(More)
Bisphenol A (BPA) is an industrial chemical used to make polymers including some used in food contact applications. Virtually complete presystemic clearance of orally administered BPA occurs in humans by metabolism to BPA-glucuronide (BPA-G), but some biomonitoring studies report low concentrations of free (parent) BPA in human blood and urine.

PURPOSE To evaluate the performance of silicone elastomer lenses in pediatric eyes with aphakia. METHODS We retrospectively studied pediatric aphakic eyes fit with Silsoft lenses (elastofilcon A, Bausch & Lomb) at the L.V. Prasad Eye Institute, India. RESULTS Seventy-four children (106 eyes) with a median age of 9.0 months (range: 1 month to 12 years)(More)
The efficient mobility management schemes based on pointer forwarding for wireless mesh networks (WMNs) with this to reduce the overall network traffic incurred by mobility management and packet delivery. The proposed schemes are per-user-based, i.e., the optimal threshold of the forwarding chain length that minimizes the overall network traffic is(More)
Estimation of water measurement is of high importance in hydrographic survey activity especially in reservoirs. Because in rainy season there is collection of slurry and mud at the bottom of dam. Because of this the depth of dam may get reduced and hence its capacity is reduced. There are number of techniques to measure the depth and each having its(More)
AIM To evaluate the efficacy and safety of fixed drug combination (FDC) halometasone 0.05% and fusidic acid 2% (group A) vs FDC betamethasone 0.12% and neomycin sulfate 0.5% cream (group B) in acute or chronic infected eczematous dermatosis, through a randomized open-label, comparative, multicentric study. MATERIALS AND METHODS A total of 152 patients(More)
The main goal of this work is to determine the optimum operating conditions of the control variables within the constraints of control variables and minimization of transmission losses at normal operating condition of the system. The upper and lower values of voltages at load bus, the lower and upper values of generator reactive powers and normal operating(More)
