Ruthenium(III) complexes of the type [RuBr2(PPh3)2L] (where L = monobasic bidentate thiosemicarbazone ligand) have been synthesized. Various physico-chemical and spectral techniques were used to determine the structural features of the complexes. Absorption spectroscopy was used to investigate DNA binding of the complexes. It indicated that the complexes bind to DNA through intercalation. The c...

A rapidly growing area of modern pharmaceutical research is the prediction of aqueous solubility of drug-sized compounds from their molecular structures. There exist many different reasons for considering this physico-chemical property as a key parameter: the design of novel entities with adequate aqueous solubility brings many advantages to preclinical and clinical research and development, al...

Different sets of molecular descriptors using the k-nearest neighbor classi¢cation method were used to make a general classi¢cation of 152 organic solvents, the classi¢cation being further improved by performing the counterpropagation arti¢cial neural network. An extensive investigation was made of the physico-chemical properties of 152 solvents in a search for quantitative structure^property r...

this study aims to determine the effect of fermentation condition and saccharomyces strains on the ph, foam property and co2 concentration of non-alcoholic beer (ma-al-shaeer). for this, the beer samples were inoculated with four different species of saccharomyces (saccharomyces rouxii 70531, s. rouxii 70535, s. ludwigii 3447 and s. cerevisiae 70424) and fermented for 48h in both aerobic and pe...

The effect of artificial pozzolan (waste brick) on the physico-chemical properties of cement manufactured was investigated. The waste brick is generated by the manufacture of bricks. It was used in the proportions of 0%, 5%, 10%, 15% and 20% by mass of cement to study its effect on the physico-chemical properties of cement incorporating artificial pozzolan. The physicochemical properties of cem...

In this research, the physico-chemical water quality parameters and the effect of climate changes onwater quality is evaluated. During the observation period (5 months) physico-chemical parameterssuch as water temperature, turbidity, saturated oxygen, dissolved oxygen, pH, chlorophyll-a, salinity,conductivity, and concentration of total nitrogen (nutrient level) as main pollutant factor have be...

the present study has been undertaken in a laboratory scale to characterize and investigate pollution potential of textile effluents from depz area in dhaka, bangladesh. collected effluent samples from five different industries were analyzed for physico-chemical parameters using field kits and standard methods, and for metals using flame atomic absorption spectrophotometer (faas). the average p...
