Abstract: N-methyl indoleWas synthesized by treating indole with iodomethane in presence of sodium hydride in the solvent medium of DMF. N-methyl -3-formylindole was synthesized by reacting N-methyl indole with POCI3 and DMF mixture in the solvent medium of orthodichlorobenzene . N-methyl-3-hydroxy methyl indole was synthesized by the reduction of N-methyl-3-formyl indole with sodium borohydride and sodium hydroxide mixture in the solvent medium of ethanol. Chloroformic ester of N-methyl-3-hydroxymethyl indole was prepared by reacting N-methyl-3-hydroxy methyl indole with phosgene and pyridine in the solvent medium of THF. 4-[N-methyl indolyl-3-methylene oxy carbonyl imino] styrene was prepared by reacting the chloroformic ester of N-methyl-3-hydroxy methyl indole with 4-amino styrene in the solvent medium of THF.Lastly the monomer namely 4-[N-methyl indolyl-3-methylene oxy carbonyl imino] styrene was copolymerized with methyl methacrylate with a peroxide initiator in the solvent medium of DMF. The monomer and the copolymer was characterized by IR, UV and NMR spectroscopy.

Abstract: Ni-Co thin films have been grown on Stainless steel substrate by galvanostatic electrodeposition from Sulphate baths containing Pyridine as Organic inhibitor. A comparative study of corrosion parameters were done in three different electrolytes; NaCl, HCl, H2SO4 by tafel extrapolation method. Pyridine is found as an effective corrosion inhibitor for Ni-Co alloy thin films and showed minimum corrosion rate in NaCl medium. The morphology and structural analysis of thin films were done by Scanning Electron Microscopy (SEM) and X-Ray Diffraction pattern (XRD), respectively. Elemental composition has been determined by Energy Dispersive X-Ray spectroscopy (EDAX). XRD confirmed that the films possessed a mixture of Cubic and hcp crystal structures.

Keywords: thin films, galvanostatic electrodeposition, inhibitor, XRD, SEM-EDAX.

Abstract: This study was undertaken to evaluate the performance of iron oxide coated sand (IOCS) as an adsorbent for the removal of heavy metals (Mn, Fe and As) from groundwater. The main parameters affecting this treatment process were examined namely the adsorbent dose, different adsorbent types and flow rate. River- bed sand of 0.5-0.85mm was collected, dried and coated with iron oxide. The coated sand was used as an adsorbent for the removal of Iron, Manganese and Arsenic from groundwater in column experiment. The uncoated sand was used as a control. The initial concentrations of Fe, Mn and As of raw groundwater collected from Bayelsa State of Nigeria, were found to be 5.423ppm for Fe, 0.092ppm for Mn and 0.001ppm for Arsenics. The water sample was spiked with 0.715ppm Arsenic to assess the efficiency of the adsorbent in removing heavy metals. The result showed that IOCS is a good adsorbent as compared with the uncoated sand (UCS). For the removal of Arsenic, it was observed..........

Abstract: The nutritional content of the leaves of CorchorustridensLinn (a less utilized green leafy vegetable) was analyzed using some analytical methods. Significant amounts of carbohydrate (7.29 %), protein (7.72 %), lipids (5.63 %), fiber (8.40 %), vitamins (Vitamins A, B1, B2, B3 and C), moisture (67.62 %) and ash (4.27 %) were found. Their amounts in this plant's leaves compares favorably well with those found in exotic vegetables. Therefore, its consumption can supplement the nutritional requirement (RDA) of its consumers. Though some amounts of anti-nutritionals were detected and quantified (Phytates, 0.33 mg/100g; Oxalates, 1.26 mg/100g; Tannins, 0.59 mg/100g and HCN, 1.11mg/100g) in the plant...........

Abstract: Infertility varies across the regions of the world and it has been estimated to affect 8-12% couples worldwide. The WHO has estimated the overall prevalence of primary infertility in India to be between 3.9 and 16.8%. In the event of infertility,couples turn to the traditional medicine which is being used over the centuries for succor as Ayurveda holds high esteem and trust in this field. Herbal drugs are cheaper, easily available and with a meager fear of any side effects. Many herbs effective for infertility are also used in folk practice which often goes unnoticed. Shiviling beej is one such unnoticed folk medicine that shows good results for counteracting infertility. It is a uterine tonic and improves the chance of conception in women suffering from infertility. An effort has been made in this paper to scientifically review and explain the role of shivlingi seeds in infertility of either sex hypothetically.

Key words: Infertility, Ayurveda, Shivilingi seeds.

Abstract: Kinetics and mechanism Ru(III) catalyzed and uncatalyzed oxidation of 5-nitroquinoline has been carried out in HCl medium at 298 K by N-haloamines (CAT, CAB, BAT and BAB). Under comparable experimental conditions, reactions showed identical kinetics with all the oxidants studied with first order dependence each on [oxidant]o, [substrate]o and [Ru(III)] and fractional-order dependence on [HCl]. Reactions were studied at different temperatures (288-308 K). Activation parameter for both Ru(III) catalyzed and uncatalyzed reactions were computed. Ru(III) catalyzed reactions were found to be 7-9 times faster. Under identical experimental conditions, the rates were higher with bromamines compared to chloramines by a factor of 3 the order: BAB > BAT > CAB > CAT. This is attributable to the difference in electrophilicities of the halo cations, Br+ and Cl+. Probable mechanism and related rate law have been elucidated.

Key words: 5-nitroquinolie, oxidation-kinetics, Ru(III), catalysis.
