The review focuses on accidents, hazards and risks in industries. Safety and security lapses are resulting in accidents and disaster in industries and hence they need to be prevented.Safety education is the proactive development of knowledge,attitude,behaviour and skill of the workers on safety. Good safe attitude,behaviour and skill evolved by the safety education contributes to the overall accident reduction programme in the industry. Safety education is primarily the process of imparting the knowledge of safe and unsafe mechanical conditions, safe and unsafe personal practices and of remedial measures.This paper deals with a brief discussion on the relevant work carried out based on published research literature. © EuroJournals Publishing, Inc. 2011.

Experimental and theoretical ultrasonic velocity of the binary mixtures of alcohols with carbon tetrachloride systems have been find at 303K, The following theoretical methods such as, Nomotos relation, Van Dael relations, Impedance relations, Junjies relation, Impedance relations, Rao relations are used to calculate the theoretical ultrasonic velocity. Theoretical values are compared with experimental values to find the merits of the relations and check the validity of theses theoretical models by using percentage error and average percentage deviations. The results are discussed in terms of inter molecular interactions occurring in the systems. © 2015, Rasayan Journal of Chemistry, c/o Dr. Pratima Sharma. All rights reserved.

The ultrasonic velocity, density and viscosity have been measured at 301 K by the ternary mixtures of alcohols (pentanol, hexanol, heptanol, octanol and decanol) with dimethylketone in carbon tetrachloride / benzene systems. From the measured values evaluated the following acoustical parameter viz. adiabatic compressibility, acoustic impedance, relaxation time, relative association intermolecular free length, free volume, available volume, molar volume, Wadas constant and Rao’s constant, Linard-John potential. The natures of intermolecular interaction in the liquid mixtures have been explained on the basis of the variation of acoustical parameter. It is found that the interaction between non-polar molecules decreases with the increase in alcohol chain length. © 2015, RASĀYAN. All rights reserved.

This article documents the serious and frequent cerebrovascular disease. The most common cause of stroke according to a specific diagnostic algorithm can be prevented by treating carotid atherosclerosis. This algorithm is insufficient and poses a significant research challenge to study in detail to discover a solution. Earlier solutions illustrate on this matter the potential of carotid ultrasound picture analysis with a high cost and innovative imaging on plaque composition & stability. This paper illustrates the potential of carotid ultrasound picture analysis towards this direction with ultrasound imaging being a low cost picture based features revealing the information on plaque composition and stability. Systematic applications are used to diagnose & find results & orient future research. A bright respective for clinical scenario is diagnosed for atherosclerotic patients in low cost. The general project developed in MATLAB platform. Finally validation of results shows both in hardware and application, the information of vulnerability or non-vulnerability of plaque is displayed.

Dielectric permittivity, refractive indices and density were measured for the mixtures of aliphatic esters, like methyl acetate, ethyl acetate and butyl acetate with aromatic hydrocarbons like o-xylene, p-xylene and m-xylene at 303K. The measurements like excess permittivity, linear correlation factor, Bruggemann factor for six binary mixtures were measured for whole concentration range. These parameters were used to predict the nature of molecular interactions of same or different kinds of molecules and solute-solvent interactions. This shows the symmetric changes in dielectric behaviour with the variation of concentration. Further theoretical permittivity rules were calculated for the above five binary mixtures models. The relative merits of these models have been discussed in terms of standard deviation and percentage deviation. ©2015 RASĀYAN. All rights reserved.
