Analysis of speed of acoustic waves in binary liquid systems through mathematical and experimental methods
Gayathri A, Venugopal T
The estimation of the speed of ultrasound in liquids is the fundamental requirement for investigating the transport properties of liquid and solid systems. The standard mathematical methods of measuring the ultrasonic velocity may be classified into three types.

Prediction of hydrophobic core using contact map and minimal connected dominating set
Mageswari R, Srinivasa Rao K, Sivakumar K
Three dimensional structure of a protein is well determined by its continuous folds. Hydrophobic (water hating) amino acids reside at the core of the protein to avoid water and therefore it dominates the hydrophilic residues.

Graph colouring problem applied in genetic algorithm
In this paper we present a hybrid technique that applies a genetic algorithm followed by wisdom of artificial crowds that approach to solve the graph-coloring problem. The genetic algorithm described here, utilizes more than one parent selection and mutation methods depending u p on the state of fitness of its best solution.

Characteristic analysis of Zn–doped CdO thin films – doping concentration effect
Usharani K, Balu AR, Nagarethinam VS
Zn–doped CdO (ZCO) thin films were deposited on glass substrates at 375°C using a perfume atomizer. Zinc concentration was varied in the films from 0 at.% to 8 at.% in steps of 2 at.% and the effect of doping concentration on the properties of CdO thin films were investigated.

Cissus quadrangualaris as green corrosion inhibitor for mild steel in acid medium
Thirumalai S, Sridevi N, Rani S
The inhibition effect of Cissus Quadrangualris extract on mild steel in 1N HCl was studied by weight loss measurement. The inhibition effect increases with increase in concentration of green inhibitor and immersion period. Studies on the effect of temperature indicated that the inhibition efficiency increased with temperature.

Determination of Compatibility nature of blends of PMMA 350000 in Toluene by Physical methods
Padmanaban R, Venkatramanan K, Elango JK
Polymer blends are capable of providing materials with extended useful properties beyond the range that can be obtained from single polymer equivalents. From the beginning of the plastic industry it has been recognized that blending yields materials with properties superior to the feature of the individual components.
