Title: Mechanical strength of fibrous concrete with waste rural materials

Authors: Sivaraja, M; Kandasamy, S; Thirumurugan, A

Abstract: This study presents reusing of locally available waste fibrous materials as concrete composites. Mechanical strength properties (compressive strength, split tensile strength, modulus of elasticity, modulus of rupture and shear strength) of synthetic fibres (nylon, plastic and tyre) with volume fractions (0.5%, 1% and 1.5%) and aspect ratios (30, 60 and 90) were evaluated. Empirical relation was proposed for mechanical strength in relation with fibre reinforcing index (FRI) and compared with experimental results. Concrete mixed with rural waste fibres improved mechanical strength.

Title: Anaerobic baffled reactor for treatment of textile dye effluent

Authors: Goel, Simmi

Abstract: In present paper, continuous anaerobic treatment technology has been developed in anaerobic baffle reactor (ABR) and some process parameters [hydraulic retention time (HRT), organic loading rate (OLR), pH and temperature] were optimized. Active bacteria for degradation were added as digested sewage sludge. Highly colored wastewater has successfully been treated in ABR. Textile industrial waste organic matter gave maximum biogas yield (1.64 ± 0.02 l/d; methane, 83%) and COD removal (71.5%) at optimum parameters (OLR, 0.500 kg/m³/d; HRT, 4 days; pH, 6.5-7.3; and temp., 30-35°C).

Title: Study of inclusion complexes of valsartan with -cyclodextrin and hydroxypropyl -cyclodextrin

Authors: Nalawade, Pravin; Kadam, Vilasrao; Hirlekar, Rajashree

Abstract: This study presents improvement in solubility and dissolution rate of valsartan (VAL) using -cyclodextrin (CD) and hydroxypropyl--cyclodextrin (HP-CD). Formation and characterization of solid inclusion complexes were investigated by DSC, FTIR, SEM, ¹HNMR and in-vitro dissolution studies. Preparation method influenced physical properties of binary mixtures. Inclusion complexes obtained by co-evaporation method showed higher in vitro drug dissolution rates.

Title: Synthesis of sulphacetamide sodium by ultrasonic irradiation

Authors: Roychowdhury, Sunanda; Mandal, Sanat Kumar; Ghosh, Sukumar; Deb, Soumitra

Abstract: An efficient method for synthesis of sulphacetamide sodium by ultrasonic irradiation at room temperature is described. Quality of product prepared by this method has been found to be comparable with standard methods using refluxing conditions.
