Lexical chains are defined as clusters of semantically related words. The Lexical chaining architecture integrates domain dependent statistical word associations into the chaining process. The statistical word associations represent an additional type of lexical cohesive relationship that is not found in WordNet. The architecture also recognizes the gloss(More)
The FT-IR and FT-Raman spectra of 2,6-Bis(chloromethyl)pyridine (BCMP) have been recorded in the regions 4000-400 cm(-1) and 3500-100 cm(-1), respectively. The total energy calculations of BCMP were tried for the possible rotational isomers. The molecular structure, geometry optimization, vibrational frequencies were obtained by the HF and density(More)
In this work, FT-IR and FT-Raman spectra are recorded on the solid phase of 5-nitro-2-furoic acid (abbreviated as NFA) in the regions 4000-400 cm(-1) and 3500-100 cm(-1) respectively. The geometrical parameters, vibrational assignments, HOMO-LUMO energies and NBO calculations are obtained for the monomer and dimer of NFA from HF and DFT (B3LYP) with(More)
Quantum mechanical calculations of energies, geometries, and vibrational wavenumbers of N-(bromomethyl)phthalimide and N-(chloromethyl)phthalimide are carried out using density functional theory (DFT/B3LYP) method with 6-31G and 6-311G(d,p) basis sets. The optimized geometrical parameters obtained by B3LYP method show good agreement with experimental data.(More)
Rapid, simple, sensitive and accurate spectrophotometric methods have been developed for the determination of Trimetazidine in pure and pharmaceutical formulations. Various methods were developed for estimation of trimetazidine .but a simple extractive photometric method using has not been developed .This method is based on the formation of chloroform(More)
The experimental FT-IR (4000-400 cm(-1)) and FT-Raman (3500-100 cm(-1)) spectra of p-(p-hydroxyphenoxy) benzoic acid have been recorded. Quantum chemical calculations of energies, geometries, and vibrational wavenumbers of p-(p-hydroxyphenoxy) benzoic acid (PPHPBA) are carried out using HF and DFT/B3LYP methods with 6-311G (d,p) basis set. The optimized(More)
The present study is aimed at developing wasteland through exploitation of Rhizobium and Glomus fasciculatum in association with Acacia mellifera and also identifying the optimum biomass accumulation in Acacia mellifera supplemented with nitrogen and phosphorus at five different dose rates (0,50,100,150 and 200 mg/kg of soil).The entire study was designed(More)
