Abstract: This paper has to be included preparation of complex for Cr ion (III) chromium chloride and aqueous iron chloride (III) with Schiff bases ligand (N, N) di methyl of the amino benzaldhyde . The prepared complexes were characterized by IR,UV and visible spectra .  Also the optical properties in the region are visible in the wavelengths (200-400)nm and different concentrations dissolved in different concentrations dissolved with ethanol were studied , for the properties of optical include the  absorbance and turbidity and refractive index from the polarization ‘ the reflectance , coefficient of finesse , critical angle and the angle of brewster , The results shows that the properties increase with increase concentration except the critical angle which directly proportional the concentration and all the results are compared with similar compounds .

Keywords: turbidity, critical, finesse, metal.

Abstract: GCMS analysis of AS gum indicated the presence of camphene (2.15 %), sucrose (23.76 %), hexadecanoic acid (37.32%), verbenol (5.12 %), octadecanoic acid (10.93 %) and 16-methyl-octadecanoic acid (20.72 %). Through the knowledge of the chemical structures of compounds in AS gum, the potential inhibition potential of the gum was ascertain and investigated using weight loss, thermometric and scanning electron microscopy methods. The gum exhibited efficient inhibition potential between the temperature and concentration ranges of 303 to 333 K and 0.1 to 0.5 g/L respectively. After examining the trend for the variation of inhibition efficiency of the gum with temperature and the magnitude of calculated values of activation and standard free energies of adsorption, the mechanism of physical adsorption was established for the adsorption of the inhibitor on the surface of zinc. The adsorption of the inhibitor on the metal surface was also found to be spontaneous, exothermic and occurred with increasing degree of association. The failure of the Langmuir adsorption model to account for the existence of molecular interaction parameter was addressed through the fitness of the Frumkin adsorption model, which revealed the attractive behavior of the inhibitor. Scanning electron micrographs of the metal with and without the inhibitor clearly revealed the formation of protective layer on the surface of the inhibitor by the gum.

Abstract: We present particular and unique solutions of Dokshitzer-Gribov-Lipatov- Altarelli-Parisi (DGLAP) evolution equations for light sea and valence quark structure functions in leading order (LO). We obtain t evolutions of sea and valence quark structure functions and x- evolutions of light sea quark structure functions from DGLAP evolution equations. The results are compared with a recent global parameterization.

Abstract: The different properties of SrSi₂ have been calculated using the plane wave ultra soft pseudo potential technique which is based on the first-principles Density Functional Theory (DEF) with Generalized Gradient Approximation (GGA). The study involves the calculations of elastic and optical properties of SrSi₂. Theoptimized lattice parameters, three independent elastic constants (C_11, C_12, and C₄₄), bulk modulus (B), shear modulus (G), Young’s modulus (Y), Pugh’s ratio (G/B), Poisson’s ratio (ν) and elastic anisotropy (A) are estimated and discussed.This is the first quantitative theoretical prediction of the elastic properties of SrSi₂ compound.Finally the optical properties of SrSi₂ are obtained and discussed in detail.

Abstract: Miscibility and thermal studies of isotactic polystyrene and poly (cyclohexyl methacrylate) blends (iPS/PCHMA) with different compositions were investigated by thermogravimetric method and differential scanning calorimetry (DSC). The thermogravimetric data under dynamic conditions (50–600°C) in an inert atmosphere shows the blends are miscible. Using DSC studies, a single glass transition temperature (Tg) for the blend confirm the miscibility of the compositions. The crystallization and melting enthalpy with composition deviates from additive rules. Comparison of the experimental and predicted results by the additive rule indicates the existence of the components interaction in the iPS/PCHMA blends. The addition of iPS improves the thermal stability of PCHMA for all compositions and the temperature ranges.

Keywords: isotactic polystyrene, poly (cyclohexyl methacrylate), miscible blends, thermal study.
