<#LINE#>Synthesis, Spectral and Pharmacological Study of Cu(II), Ni(II) and Co(II)  Coordination Complexes<#LINE#>Rakhi@Chaudhary,Shelly<#LINE#>1-5<#LINE#>ISCA_RJCS_2011_01_June_02.pdf<#LINE#>Dept. of Applied Sc. and Humanities, Haryana Engineering College, Jagadhri – 135003, Haryana, INDIA <#LINE#>22/4/2011<#LINE#>7/5/2011<#LINE#>Complexes of Cu(II), Ni(II) and Co(II) with 2,5–Dihydroxy butyrophenone thiosemicarbazone(L) / 2,5–Dihydroxy benzophenone thiosemicarbazone(L) as primary ligand and 2,2’-bipyridyl(L) as a secondary ligand have been synthesized. Complexes were characterized by analytical data, molar conductance, magnetic measurement, electronic spectra, IR spectra and thermogravimetric analysis. The stereochemistry of the coordination complexes has been confirmed on the basis of electronic, spectral and magnetic moment studies. Racah’s interelectronic parameter(B), Cubic Ligand field splitting parameter (10 Dq) and Nephelauxetic ratio(), g, , h have also been calculated and it has been  found that the values are in accordance with the stereochemical structure of the coordination complexes. Elemental analysis and spectral studies suggest the octahedral stereochemistry for all the complexes. Ligands and their complexes with Cu(II), Ni(II) and Co(II) were also screened for their inhibitory effects against four organisms viz; S.aureus, B.megaterium, B.cereus and E.coli  by cupplate method. The results of the evaluation of antibacterial activity show that all the synthesized complexes exhibit considerable activities towards all the four pathogenic bacteria. The activity of the mixed complexes has been found to be greater than those of the metal salts and ligands. Moreover, it has also been noticed that the thiosemicarbazones show low activity towards E. coli.  <#LINE#> @ @ You Y., Zheng X., Young R. and Ahn B.,  Archiv. Pharma.

Acoustic Impedance (Z) has directly been measured by using a new technique based on pulse echo reflectory method, while ultrasonic velocity has been measured by t method. These data have been used to compute densities, Intermolecular free length(L), molar volumes(V), excess intermolecular free length(L), isentropic compressibility(K), excess acoustic impedance(Z), excess molar volumes(V), excess isentropic compressibility (K). The values of L, V , K are negative over the wide range of composition for all the studied binary mixtures, while the values of ZE are found positive. The changes in the thermo acoustic parameters as a function of variations in the composition and chain length of alkyl groups in alkanol molecules are discussed in terms of the intermolecular interactions.<#LINE#> @ @ Kenichi Tozaki A., Mitsunobu Kimura, Naoki Komatsu and Satoshi Itou, An Improved Method to determine Complex Acoustic Impedance Using a Piezoelectric Resonator, J.

The packed columns are useful for achieving mass transfer between two phases, gas and liquid.  This paper inspects the performance of two separation units. In the first step, the efficiency of the de-carbonator system will be specified, and then the capability of improving the rate of dissolved gas removal by using professional types of packing will be evaluated. The concentration of solute (CO) in a dispersed phase (water) has measured as a function of packing height. Also, new correlations for mass transfer coefficient in the gas phase have been predicted. In the second step, the examination of the sedimentation tank performance will be tested, by using the jar test, and then the best chemical additives concentration will be specified. The results show that the rate of dissolved gas removal can be improved when the area of contact between the gas and liquid streams is increased by using the professional types of packing. Also, the accuracy of chemical dosing for polyelectrolyte and ferric chloride in the sedimentation section improves the performance of the pretreatment section and reduces the chemical additives consumption. The backwash processes for sand filters and the period of replacement for fine filters has been improved after regulating the methods of separations. <#LINE#>05/5/2011<#LINE#>22/5/2011<#LINE#> Packed columns are used for the removal of contaminated gases such as carbon dioxide from drinking water and industrial wastewater.

Streptomyces virginiae was the most producer of a diffusible dark brown pigment on both peptone-yeast extract and tyrosine liquid medium. Some factors affecting on the pigment production were studied. The optimum pH was observed at 6 with 10 days of the Streptomyces age and five days of incubation on a rotary shaker (180 rpm) at 30 ◦C. The intensity of the pigment was affected by addition of carbon, nitrogen and phosphorus sources. Co, Mg and pb SO4 were increased the intensity of the pigment production. The pigment produced at optimum condition had been used to dye and print the wool fabrics, the color strength values and fastness properties of samples were investigated. At the optimum conditions the dyed and printed wool fabrics posses color strength values 12, 10.5 respectively and very good fastness properties of washing,, perspiration and light fastness. The antimicrobial activity of the extracted pigment has been investigated.  <#LINE#> @ @  Miyaura J. and Tatsumi C. Studies on the Antibiotics from Actinomycetes.

Results of inhibition efficiencies obtained from both methods are in good agreement with each other. Efficiency of inhibitor increases with increasing concentration of inhibitor as well as that of HCl solution. The efficiencies have been compared with those of parent amine from which Mannich bases have been derived. Inhibition efficiencies of synthesized Mannich bases have been found much more than their parent amine. It was observed that inhibition efficiencies of amine increases with increasing concentration of amine whereas it decreases with increasing concentration of acid. <#LINE#> @ @  Sampat S.S. and Vogra J.C., Study of corrosion inhibition efficiency of some Schif’s bases on aluminium in trichloroacetic acid solution Corrosion Science, 14,591(1974) @No $ @ @   Upadhyay R.K. and Mathur S.P.,Effect of Schiff's Bases as Corrosion Inhibitors on Mild Steel in Sulphuric AcidE-Journal of Chem., 4(3), 408-414(2007) @No $ @ @  Mahor D.K.,Upadhyay R.K. and Chaturvedi A.,Study of corrosion inhibition efficiency of some Schif’s bases on aluminium in trichloroacetic acid solution, Rev.Roum.Chim, 55, 227 (2010) @No $ @ @  Sethi T.

The wastewater from the studied CPP had a pH in the range of 3.4-3.6 with TSS and turbidity of 1000 and 150 mg·L-1, respectively. The selection and dose optimization of the cationic coagulants (Ferric chloride (FeCland Aluminium sulphate (Al[SO)), inorganic polymer coagulant (Poly Aluminium Chloride (PAC)) and a commercial coagulant (brand name (N8100)) were carried out. The results showed that N8100 at 5 mg·L-1 dose and pH 6-8 gave the best performance with the final wastewater had TSS 10 mg·L-1, Turbidity 3 mg·L-1, Fe 0.11 mg·L-1, Mn and Al each 0.01 mg·L-1 (undetectable). These results were below the limit set by the Indonesian wastewater standard for coal mining industry. The designed precipitation system used for the removal of total suspended solid consisted of equalization pond (960 m), inlet channel with baffles and coagulant-lime control for optimum mixing  and three identical sedimentation ponds (each with the lower dredge volume of 105 m and the whole pond volume of 675 m). These ponds retained the sediments for 3 months prior to cleaning. Coagulants N8100, FeCl, Al(SO3 andPAC had the operating costs 10.03 US$/day(lowest) 118.95, 22.06 and 21.77 US$/day, respectively.  Besides the low operating cost N8100 had produced least sediments compared to FeCl, Al(SO3 andPAC. <#LINE#> @ @ Belkin H.E. and Tewalt S.J., Geochemistry of Selected Coal Samples from Sumatra, Kalimantan, Sulawesi, and Papua, Indonesia.

The lead sulphate and sodium selenosulphate are used as source of materials to obtain lead selenide films. The ‘as-deposited’ films were uniform, well adherent and dark brown in color. The films were characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM), optical absorption, and electrical conductivity measurement techniques. The XRD study confirms polycrystalline nature in FCC structure. The absorption spectrum showed an exponential edge. Lead selenide films showed an optical band gap of 0.325 eV with absorption coefficient 10 cm-1. The room temperature electrical conductivity was of the order of 10-3 (-cm)-1. The film exhibits n-type conductivity with activation energy of 0.153 eV. <#LINE#> @ @ Lofersky J.J., J. Appl.

A biological study was performed by isolation in solid agar slant media and contained cell shapes was identified by using an electron microscope. It was identified for seven different isolates that this mixed culture was gram positive. These strains were cultivated on substrates with BTEX as a carbon and energy sources. From seven isolates, Bacillus sphaericus was identified for biodegration of BTEX. All isolates cultivated in a pH range from 3-11 with an optimum range of 6-8, which was applicable for the temperature range of 15-45C giving a optimum range of 25-30C. The batch studies were carried out at five different initial BTEX concentrations ranging from 25-500 mg L-1. B. sphaericus was able to give 100% degradation of BTEX at 200 mg L-1 after 72 hr. but for xylene it was around 90%. Finally the results signify that the B. sphaericus degrades BTEX at a faster rate and this strain can be used proficiently in biofilter for treating highly polluted air streams.   <#LINE#> @ @  Mohseni M. and Grant A.D., Bio filtration of mixtures of hydrophilic and hydrophobic volatile organic compounds, Chem.

Due to the presence of LiOH, the ligand used its lactim form in all complexes and showed a variety of modes of bonding viz. (NNO)2-, (NO) with or without O- bridging per each metal ion. The mode of bonding and basicity of the ligand depend mainly on the type of the metal ion. The obtained Co(II), Ni(II) and Cu(II)- complexes have the square planar geometry, whereas, Fe(III) and VO(II)- complexes have the octahedral geometry. LiOH behaves as a coligand in case of Fe(III)- complex whereas, it behaves as a deprotonating agent in case of the rest of complexes.The investigated complexes exhibited low to moderate activities against S. aureus bacteria. For clarifying their proposed structures, the complexes were subjected to elemental analysis and spectral studies.  <#LINE#> @ @ Finar I.L., Organic Chemistry. 6th ed, Hong Kong, The Continental Printing Co.

At optimum treatment conditions (pH 8, contact time of 4 hrs and temperature of 40C) 84.9% As (III) ion was removed from aqueous solution. Langmuir and Freundlich isotherms were used for equilibrium studies. Freundlich isotherm was better fitted with experimental data. For kinetic studies, pseudo second order kinetic model (R =0.997) appeared to be more suitable model to describe As (III) ion biosorption. The positive value of S° and H° depicts the feasibility of the biosorption and the spontaneous nature was confirmed by negative value of . Fourier Transformation infrared spectrometry (FTIR) and Scanning Electron Microscopy (SEM) were used for characterisations of maize leaves biomass. <#LINE#> @ @ Amin N., Kaneco S., Kitagawa T., Begum A., Kastumata H., Suzuki T. and Ohta K., Removal of arsenic in aqueous solutions by adsorption onto waste rice husk, Ind.

The products were refluxed with N–benzyl-N-phenylhydrazine in acetic acid. With the help of micro- and IR-spectral analysis, the molecular structures of the synthesised products were determined. These were ascertained using H NMR at 60MHz and TMS as internal standard. Biological activity of the derivatives against gram-positive Cocci and Bacilli as well as gram-negative Bacilli was tested and found to vary widely from inactive to highly active, which could prove to be of practical pharmaceutical application. <#LINE#> @ @ Mulongo George, Mbabazi Jolocam, Odongkara B., Twinomuhwezi H. and Mpango G.B., New biologically active compounds from 1,3-diketones, Res.
