The effect of varying concentration of [substrate], [oxidant], [H +], added neutral salt have been studied. It has been found that, the order of reaction with respect to [oxidant] and [substrate] found to be unity from the slope of plots log k vs log [sub]. The rate of reaction increases with decrease in pH of perchloric acid. Hammett's acidity function and activity of water have been studied. Effect of temperature has been studied. Activation parameters were computed. The plot of ΔH* vs ΔS* is linear. The effect of dielectric constant of the medium indicates the reaction to be +ve iondipole. The result of oxidation products have been identified.

A rapid and sensitive LC-MS-MS method for the determination of alverine (ALV) and its major metabolite, monohydroxy alverine (MHA), in human plasma using imipramine as an internal standard was developed and validated. The analytes were extracted from 0.5 mL aliquots of human plasma by solid phase extraction, using oasis cartridge. Chromatographic separation was carried on Thermo Gold C18 column (50 × 4.6 mm, 5 μ) at 30 °C, with isocratic mobile phase, a flow rate of 0.4 mL/min and a total run time of 3.5 min. Detection and quantification were performed using a mass spectrometer in the selected reaction-monitoring mode with positive electrospray ionization at m/z 282.3 →91.11 for alverine, m/z 298.3 → 106.9 for mono-hydroxy- alverine, and m/z 281.0 → 86.0 for internal standard (IS) respectively. This assay was linear over a concentration range of 0.060-10 ng/mL with a lower limit of quantification of 0.060 ng/mL for both alverine and monohydroxy alverine. The coefficient of variation for the assay precision were <9.18% and <8.44%, the accuracy were >104.66% and >100.38% for alverine and monohydroxy alverine respectively. This method was successfully applied to a pharmacokinetic study after oral administration of alverine citrate 60 mg capsule in healthy male subjects.

Precision agriculture is finding its roots in India. PA always deals with the accuracy and timely information about agriculture products. With the rapid development of computer hardware and software technology, the application of image processing technology in the agricultural research are playing key role [1]. Also, with the advantages of superior speed and accuracy, computer vision has attracted it as an alternative to human inspection [2]. In this paper, we have described a novel application of computer vision and color image segmentation for automating the precise yield prediction process of gerbera flower yield from the polyhouse images. The purpose of the present study is to design a decision support system that could generate flower yield information and serve as base for management & planning of flower marketing. Current study has applied the color image segmentation technique using threshold, to extract the flowers from the scene. Color is considered a fundamental physical property of agriculture products and foods in information analysis [3]. Using HSV color space and histogram analysis, flower color definition is done. Then by the image segmentation process, flowers were separated from the background & detected in the images. Image set with 75 images were tested with this technique. © 2013 IEEE.

The Chalcones Condensed with hydrazine hydrate in ethanol to get the corresponding novel pyrazolines (I-X). The compounds were synthesized and characterized by TLC, melting points, IR, 1H-NMR and mass spectra. The synthesized compounds have been screened for their antimicrobial activity against different micro-organisms. All the compounds show moderate to good activity against different micro-organisms.
