Molecular Interaction Studies in Ternary Liquid Mixtures of Quinoline at Varying Temperatures

Density r, Viscosity η, and ultrasonic velocity u, have been measured in pure Quinoline, o-cresol, m-cresol, p-cresol and methanol and in their ternary liquid mixtures with quinoline and methanol as common components at 303.15, 308.15, 313.15 and 318.15K over the entire range of composition. From these experimental data, various thermo-acoustic parameters such as excess molar volume VmE, excess ultrasonic velocity uE, viscosity deviation Δη and excess Gibb’s free energy of activation for viscous flow ΔG*E have been calculated. The deviation/excess parameters were plotted against the mole fraction of quinoline over the whole composition range. The observed negative and positive values of deviaiton/excess thermo-acoustic parameters were explained on the basis of intermolecular interactions present in these mixtures

INTRODUCTION COMPETITORS FROM A LARGE RANGE OF DISTINCT DATA

Our analysis of the belief that four sets of data in the real world are established by trust and classification is exactly the same, and all are precise and precise propositions. Compose Comparative Trust BSM has demonstrated its ability to measure such large datasets. Analyzing social data from four realities in the real world suggests that this is not just a clear idea, but also considers the range and overall impact of trust as a reward. Second, this way of thinking is based on temples that concentrate more money on the user's ability to use, but ignore the results of their self-esteem. The effects are unclear or ambiguous. Trusted BSM proposes how to create a proposal based on a matrix. As a result, Trust BSM creates the most advanced BSM Recommendations Board with a clear, clear and reliable impact for users with active user products. The proposed policy of social information is the first BSM transfer

Volumetric properties of binary mixtures of cyclohexane with 2-ethoxyethanol at 303.15, 308.15, 313.15 and 318.15 K

1206-1210The excess molar volumes (VmE) for binary liquid mixtures of cyclohexane+2-ethoxyethanol have been calculated from the experimental values of density and ultrasonic velocity at temperatures 303.15, 308.15, 313.15 and 318.15 K and atmospheric pressure over the entire composition range. The results have been used to estimate the partial molar volumes m,i of the components. The excess values have been fitted to Redlich-Kister polynomial equation. The changes of VmE and with composition and temperature have been discussed with reference to the nature of interactions between the component molecules

FASTER AND ACCURATE MATCHING TECHNIQUE FOR PALMPRINT IDENTIFICATION

This paper presents the palmprint identification based on 2D and 3D palmprint matching methods. The methods are more efficetive, less extraction time, less matching time and accurate for palmprint matching. Firstly, we remove noises from palmprint images using hybrid median filter methods. Secondly,In 3D palmprint matching follow two arguments and proposed a  new method for palmprint features. The proposed method has better perfomance and also significantly reduce the templete size. This method of 3D shape palmprint to either convex or concave. The experimental results shows that the better palmprint matching, more accurate and less extract time features compare to existing methods

Development and validation of RP HPLC method for determination of metformin and sitagliptin in bulk and pharmaceutical dosage form

A simple and rapid reversed phase-high performance liquid chromatographic method was developed for simultaneous determination of Metformin and Sitagliptin in Tablet Dosage form. The elution was done with a mobile phase of Water: Methanol (60:40) on Intersil-BDS C18 column (250 × 4.6 mm, 5 μm particle size). The wavelength detector was set at 258 nm. Retention times for Metformin and Sitagliptin were around 2.869 min, 3.942 min respectively. The reliability and analytical performance of the proposed HPLC procedure were statistically validated according to the respect of linearity, ranges, precision, accuracy, repeatability, reproducibility, detection and quantification limits. Linear ranges were established between 20-80 μg/mL for both the drug. The LOD and LOQ for Metformin were found to be 0.663, 1.92 and for Sitagliptin were found to be 0.405, 1.228 respectively. The described High Performance Liquid Chromatography method was successfully employed for the analysis of pharmaceutical formulations containing combined dosage for

Note The carvingwidth of hypercubes �

www.elsevier.com/locate/disc The notion of the carvingwidth of a graph was introduced by Seymour and Thomas [Call routing and the ratcatcher, Combinatorica 14 (1994) 217–241]. In this note, we show that the carvingwidth of a d-dimensional hypercube equals 2 d−1. © 2006 Elsevier B.V. All rights reserved
