A multilayer perceptron neural network approach for the solution of hyperbolic telegraph equations.

Neural networks have been extensively used for solving differential equations in the past, but they rely mostly on computationally expensive gradient-based numerical optimization procedure for solving differential equations. In this work, we are introducing a faster way to train neural networks for solving differential equations based on extreme learning machine algorithm. This algorithm is much faster as compared to traditional approaches, and it also provides highly accurate results.

In vitro studies on effect of different concentration of NaCl on Jatropha curcas.

Short-term effect of different concentrations of NaCl on callus cultures of Jatropha curcas was investigated at different concentration of NaCl (0, 20, 40, 60, 80,100 mM). Results showed a decrease in fresh weight of callus cultures when subjected to increasing concentration of salt in the medium. Callus morphology correspondingly changed from off-white to blackish-brown above 40mM to acutely necrotic stage at 100 mM NaCl.

Antiinflammatory Activity of Piper longum Fruit Oil.

In the present study, antiinflammatory activity of the Piper longum dried fruit's oil was studied in rats using the carrageenan-induced right hind paw edema method. The activity was compared with that of standard drug ibuprofen. The dried fruit's oil inhibited carrageenan-induced rat paw edema.

ICH guidance in practice: validated reversed-phase HPLC method for the determination of active mangiferin from extracts of Mangifera indica Linn.

This study presents the development and validation of a reversed-phase liquid chromatographic method for the determination of mangiferin (MGN) in alcoholic extracts of mangifera indica. A Lichrospher 100 C(18)-ODS (250 x 4.6 mm, 5 microm size) (Merck, Whitehouse Station, NJ) prepacked column and a mobile phase of potassium dihydrogen orthophosphate (0.

Validation and application of high-performance liquid chromatographic and spectrophotometric methods for simultaneous estimation of nebivolol and hydrochlorothiazide: a novel approach to multivariate calibrations by R-Software Environment.

A fast, simple reversed-phase HPLC method and two spectrophotometric methods based on principal component regression and partial least squares calibrations were developed for determination of nebivolol (NEB) and hydrochlorothiazide (HCTZ) in formulations without prior separation or masking. The HPLC assay utilized a Phenomenex-Luna RP-18(2) 250 x 4.6 mm, 5 microm column with acetonitrile--0.
