Biogeochemical Study of Copper Mineralized Zone near Kalyadi, Karnataka

Ultramafics intercalated with metasedimentaries in Kalyadi area host copper mineralization and the overburden of this mineralized zone has been studied from the point of geobotany and biogeochemistry. In the mineralized zone, the soil cover is very thin (1–1.5 ft), and supports sparse and stunted vegetation. Shrubs dominate the herbs and trees. Dodonaea viscosa, Cassia auriculata, Maytenus emerginata, Pavetta indica, Erythro xylon, Tecoma stans, Aerva lanata, Hyptis suaveolens, Atylosia albicans, Stachyterphyta indica, Chromolaena odarata are the plant species which have been studied and sampled. Morphologically, no significant changes could be made out from the species growing in the mineralized area. Depending upon the distribution and homogeneity of the plant species sampling has been carried out following a grid pattern. The elements analyzed for plant species and soil included Cu, Cr, Zn, Ni, Co, Mn and Mg. Trace element study of soil and floral species indicates moderate but inhomogenous dispersion of Cu from the bed rock source. Only a few samples of Leguminosae, Dodonaea viscosas, Erthyron xylon, Leucas ciliata and Pavetta indica showed slightly higher values. Thus, these species are considered as better up-takers of copper. Restricted Cr, Ni and Co in almost all the analyzed plants could be due to their lesser mobility. The overall biogeochemical observation has helped to recognize Leucas ciliata, Cassia auriculata and Erthyron xylon as species slightly favourable for Cu up-take and could serve as local indicators. Statchyterphyta indica is recognized as a good up-taker of Zn

Study of ZnO nanoparticle-supported clay minerals for electrochemical sensors, photocatalysis, and antioxidant applications

In view of the current study's demonstration of the synthesis of clay-doped ZnO composites, we present a low-cost method for producing clay-metal oxide (clay/ZnO). Utilizing the solution combustion technique, a composite of clay/ZnO was produced utilizing citric acid as both a fuel and a complexing agent. The hexagonal unit cell structure of the created clay/ZnO may be seen using XRD patterns. The ZnO-infused clay was visible in FE-SEM micrographs as homogenous, sphere-shaped ZnO. The possible involvement of clay/ZnO photocatalytic activity in the UV-induced photodegradation of malachite green dye was investigated. The 90% degradation rate shows the composite's outstanding photocatalytic degradation capacity. The resulting substance was electrochemically analyzed using a constructed electrode in 0.1 M KOH electrolyte. It increased its sensor capabilities, which now include chemical and biomolecule sensors, and it excelled in cyclic voltammetry-based redox potential studies. To efficiently evaluate chemically synthesized NPs for electrochemical, sensing, and photocatalytic applications, this study intends to create a solution combustion procedure for the synthesis of clay/ZnO nanocomposite using urea as fuel

Efficient Auditing for Outsourced Database with Token Enforced Cloud Storage

Database outsourcing is one of the important utilities in cloud computing in which the Information Proprietor (IP) transfers the database administration to the Cloud Service Provider (CSP) in order to minimize the administration cost and preservation expenses of the database. Inspite of its immense profit, it undergoes few security issues such as privacy of deployed database and provability of search results. In the recent past, few of the studies have been carried out on provability of search results of Outsourced Database (ODB) that affords correctness and completeness of search results. But in the existing schemes, since there is flow of data between the Information Proprietor and the clients frequently, huge communication cost prevails at the Information Proprietor side. To address this challenge, in this paper we propose Efficient Auditing for Outsourced Database with Token Enforced Cloud Storage (EAODBT). The

In the present study, to assess the efficiency of previously reported SCAR 4 marker for marker assisted selection was validated by screening the marker in a total of 226 F2 mapping population derived from a cross between male sterile (IIHR10521AB) and a male fertile pure line (IIHRMY7) maintained at IIHR along with bulk segregant analysis. The results showed that the marker segregated in the F2 population showing that it is linked to sterility locus. The marker was also validated by screening 12 different apetalloid male sterile lines maintained at IIHR, the results of amplification gave clear and similar band size amplicons present in parents in all the apetalloid sterile lines confirming that it is linked to male sterility and hence this study is significantly useful and can offer a powerful tool for the efficient selection in MAS breeding programmes in marigold.Not Availabl

Structure property relationship of a new nonlinear optical organic crystal: 1-(3,4-Dimethoxyphenyl)-3-(3-fluorophenyl)prop-2-en-1-one for optical power limiting applications

A new organic potential nonlinear optical (NLO) material 1-(3,4-dimethoxyphenyl)-3-(3-fluorophenyl)prop-2-en-1-one (DMP3FP) is crystallized in acetone. The single crystal X-ray diffraction data shows that material crystallizes into centro-symmetric orthorhombic space group Pbca with a = 15.6552(6) Å, b = 8.5571(3) Å, c = 20.7697(7) Å. The functional groups in DMP3FP molecule are identified by Fourier Transfer Infrared (FTIR) spectra. The thermal stability and melting point are determined using thermo gravimetric analysis/differential thermal analysis (TGA/DTA). Using UV Visible spectral studies direct band gap energy of the crystal is determined to be 3.19 eV. The nonlinear absorption coefficient and optical power limiting of the crystal was studied using Z-scan technique. The crystal exhibits a self-focusing effect at a wavelength of 532 nm showing optical limiting and reverse saturable absorption by having excited state absorption coefficient greater than ground state absorption coefficient.
