A study was conducted to investigate to study accumulation of heavy metals in soil samples collected from the surface of the soil near Siddheshwar dam area in Hingoli, Maharashtra. The concentration of these metals was determined by UV-spectrophotometer. The concentration of heavy metals was found to be below the permissible range. The physico-chemical characteristics like temperature, electrical conductivity, and water holding capacity, soil moisture, pH, chloride, Fluoride, organic carbon, organic matter, alkalinity, calcium, and magnesium were also been studied. These parameters have been detected by standard methods.<#LINE#>Srivastava K.P. and Singh Vikash Kumar@Impact of AirPollutionon pH of soil of Saran@Bihar, India, ResearchJournal of Recent Sciences, 1(4), 9-13 (2012)@Yes$Sharma B.K.@Environmental chemistry@IV ed, GoelPublication House, Meerut, (2001)@Yes$Eruola A.O., Ufoegbune G.C., Eruola A.O., Awomeso J.A.and Abhulimen S.A., Assessment of Cadmium@Lead and Ironin Hand Dug Wells of Ilaro and Aiyetoro, Ogun State, SouthWesternNigeria@Research Journal of Chemical Sciences,1(9), 1-5 (2011)@Yes$Biswal D., Muralidhar J. and Patra,@Heavy metalconcentration in sediment water of river Kusei, IndianJournal of Environmental Health@, 40, 349-358 (1998)@No$Patil B.H. and Srivastava V.S.,@Accumulation of heavy metalsthrough industrialization, International Journal of ChemicalSciences@, 2(4), 637-641 (2004)@No$Sachan S.

Zinc borate which represent inorganic fire retardant was used to coating structural composite consist of araldite resin reinforced with carbon and Kevlar fibers to increase the flame retardancy for these structures , where a surface layer from zinc borate was used as a coating layer of (4mm) thickness. The material was exposed to a direct flame generated from Oxyacetylene torch (3000�C) with different flame exposure distances (10, 15, 20mm), and study the range of resistance of retardant material layer to the flames and protected the substrate. For enhance the action of zinc borate, a hybrid fire retardant was formed by added antimony trioxide with various quantities (10%, 20%, 30%) to zinc borate to react flame and exposure this hybrid material to same flame temperature and exposure distances. Method of measuring the surface temperature opposite to the flame was used to determined the heat transferred to composite material. The optimum results was obtained with (30%) antimony trioxide mixed with zinc borate and exposed distance (20mm).<#LINE#>Stark N.M., White H.R., Mueller S.A. and Osswald T.A.@Evaluation of various fire retardants for use in wood flourpolyethylenecomposites@Polymer Degradation andStability, 95, 1903-1910 (2010)@Yes$Levchik S.V.@Introduction to flame retardancy and polymerflammability, Morgan AB, Wilkie CA@editors, flameretardant polymer nanocomposites, John Wiley & Sons;NY, USA, 1–29 (2007)@No$Horrocks A.R. and Price D.@Fire retardant materials, Taylorand Francis Group@LLC (2010)@No$Obidiegwu M.U. and Ogbobe O.@Mechanical andflammability properties of low density polyethylene/kolanitida wood fiber composites@Academic ResearchInternational, 2(3), 230-238 (2012)@Yes$Bhattacharjee C.R., Sharon M. and Nath A.@Synthesis ofNano Composites from Plant-based Sources@Res.

Essential oils (EO) HS1 and HS2 extracted from leafy stems of H. spicigera by hydrodistillation after different harvesting periods were characterized by gas chromatography/flame ionization detector (GC/FID) and gas chromatography/mass spectrometry (GC/MS). The cytotoxicity of these volatile extracts was tested in order to assess their antiproliferative activity on cancer cells MCF-7 by the resazurin test. Chromatographic analysis revealed several major compounds depending on the harvest period of vegetable. Sample HS1 was characterized by -pinene (16.9%), sabinene (13.8%), -pinene (9.6%) and 1,8-cineole (9.6%), while HS2 was potentially rich in caryophyllene (53.2%), caryophyllene oxide (5.4%) and -humulene (3.8%). Biological investigations performed have shown that HS1 and HS2 were cytotoxic against MCF-7 cells. Inhibitory concentrations values (IC50) determined for this purpose were 170 and 84 �g/mL respectively for HS1 and HS2. Major compounds of the EO should be responsible for this inhibitory activity.<#LINE#>@@Hutchinson J. and Dalziel J.M., Flora of West Africa, 2ndedition, Crown agent, London, 2(2), 466 (1963)@No$Kerharo J. and Adam J.G.@@La Pharmacopée SénégalaiseTraditionnelle-Plantes Médicinales et Toxiques, EditionVigot Frères: Paris (1974)@No$@@Adjanohoum E.J., Ahyi M.R.A., Ake Assi L., Akpgana K.,Chibon P., El-Hadji A., Eyme J., Garba M., Gassita J.N.,Gbeassor M., Goudote E., Guinko S., Hodouto K.K.,Houngnon P., Keita A., Keoula Y., Klugla-Ocloo W.P., LoI., Siamevi K.M. and Taffame K.K., MédecineTraditionnelle et Pharmacopée :@No$Lambert J.D.H, Gale J.@Arnasson J.T. and PhilogèneB.J.R.@Insect.

Trace element contents of the granitoids decrease from granodiorite to the granites except Rb which behave in an opposite way. This results in a chemical gradient from granodiorite through the migmatites to the granites. The chondrite normalised rare earth elements trends indicate strongly fractionated rare earth element patterns with enriched light rare earth elements and an increasing negative Eu anomaly from the granodiorite to the granites. The gradational trace elements petrochemistry of the rock units and the antipathetic relation between Sr and Rb., Ba and Rb/Sr suggest that the granitoids are probably I-type, genetically related to a common source by fractional crystallisation. The within plate syn- to late-orogenic signatures suggest that the rocks were generated in a syn- to late-orogenic within plate tectonic setting.<#LINE#>Burke K.C. and Dewey F.J.@Orogeny in Africa, In: T.F.J.Dessauvagie and A.J.

Therefore, there is a need for developing better solid-liquid extraction techniques for leaching natural colorants from plant materials for applications in plant research concerned on boiling and solvent extraction. Water, methanol and acidified methanol were used as solvent to extract Carotenoids as the natural dyes from plant, as well as dyeing industries. The influence of ultrasound on natural colorant extraction from different potential dye yielding plant materials has been studied in comparison with magnetic stirring process as control. The color yielding plant materials used in the present study include Daucus carota Linn. (carrot). Analytical studies such as UV-VIS spectrophotometry and gravimetric analysis were performed on the extract. The dyes produced were dyed on silk fabric and tested for their colour fastness to washing properties. Several mordants were also used for fixing the colour on the fabrics. Moreover, the dyes obtained from the plant may also be alternative sources to synthetic dyes for the dyeing of natural silk fibre. Therefore, this methodology could be employed for extracting coloring materials from plant materials in a faster and effective manner.<#LINE#>@@Bechtold S. A., Chatterjee S. T., Chatterjee C.

After separation, the suspension is recycled to the bottom via a stand pipe or down comer. The behavior of CFB differs from a conventional fluidized bed, because of absence of bubbles and entrained flow of solids. A CFB operates at much higher gas velocities than those used in conventional fluidized bed and lower than those used in pneumatic conveying. Circulating fluidized bed is finding increased industrial applications in recent years. One such application is extension of a CFB for granular materials drying. It is essentially a process of simultaneous heat and mass transfer and a very common process in many of the chemical process industries. In this article an attempt was made to study the hydrodynamic properties of ragi in Circulating Fluidized Bed. Experiments were conducted in a column of 0.05m internal diameter and 1.6m long covering a wide range of operating conditions. The transport velocity was estimated by emptying time technique, the effect of pressure drop with axial co-ordinate for different gas mass flux and solids circulation rate, the effect of voidage and the effect of solid circulation rate with pressure gradient. In the present work an attempt has been made to dry in the riser of the circulating fluidized bed covering a wide range of operating parameters. The effects of various operating parameters such as initial moisture content on exposure time, moisture content with drying rate and relative moisture content with exposure time with varying temperature of heating medium. The results obtained are quite satisfactory with literatures.<#LINE#>@@Og Sin KIM, Dong Hyun LEE and Sang Done KIM,Drying characteristics of fine powders in an inert mediumcirculating fluidized bed, J. of Chem.

N-n-octylcyclohexylamine (N- n -OCA) has been used for quantitative extraction of selenium (IV) and tellurium (IV) in dichloromethane (DCM) � xylene solvent mixture. The quantitative extraction of selenium (IV) was observed in the acidic range of 0.4 � 0.8 M hydrochloric acid (HCl) with 0.05 M N- n � OCA in DCM � xylene. Whereas that of tellurium(IV) was observed in the acidic range of 6.8 to 7.5 M HCl. Selenium(IV) and tellurium(IV) from the organic phase were stripped with 1:1 NH and determined spectrophotometrically with 1-(4�-Bromophenyl)- 4,4,6-trimethyl-1,4- dihydropyridine-2-thiol (4�-bromo PTPT) at 350 nm and 440 nm, respectively. The optimum extraction conditions were evaluated by a critical study of acidity, extractant concentration, period of equilibrium and effect of diluents. Sequential separation of selenium(IV) and tellurium(IV) has been achieved taking the advantage of difference in acidity for the extraction flow sheet � I. The separation of these metal ions from one another in varying ratio of selenium(IV) : tellurium(IV) and multi components mixture of commonly associated metals was found to be possible by this method. It was successfully applied for analysis of selenium(IV) and tellurium(IV) in real sample such as alloys, pharmaceutical samples and thin film.<#LINE#>@@Combs G.F. and Combs S.B., The role of Selenium inNutrition, New York: Academic Press Inc, (1986)@No$@@Pinho J., Canario J., Cesario R. and Vale C.A., rapid aciddigestion method with ICP-MS detection for thedetermination of selenium in dry sediments, Anal.

Cl-, Br-, NO3- , ClO4-, SO42- and AcO-. The obtained complexes have Oh, squareplanar (D4h- symmetry) and square pyramid arrangements. The complexes fulfill the strong coordinating ability of Cl¯, Br¯,NO3¯ and SO42- anions. Depending on the type of the anion, the ligand coordinates the copper(II)- ions either through itslactam (SO42- and ClO4-) or lactim forms (the others). For the copper(II)- isatinic complexes the antimicrobial activit showsa gradual change with change of the coordinated anions. Also, depending on the type of the anion, the order of theantimicrobial activity is as follows Cl- > SO42- > Br-.<#LINE#>@@Finar I.L., Organic Chemistry. 6th ed, Hong Kong, TheContinental Printing Co.
