Gamma-rays interaction parameters with six polymer and plastic materials have been computed and investigated for their shielding behaviours in the experimental energy range 10-1400keV. Low mass-density and ability to transform into thin-sheets of H-containing plastic and polymer materials generate the curiosity for present study. Gamma Ray Interaction Coefficients (GRIC)-toolkit: a computer program designed in MS-Excel, 2007 for the investigation. The toolkit has the capability to compute different parameters linked to shielding properties of the sample-material such that; mass attenuation coefficients (μ/ρ), mass energy absorption coefficients (μen/ρ), equivalent atomic number (Zeq), KERMA (kinetic energy released per unit mass). Polyvinyl Chloride (PVC) seems to be the best shield for gamma radiations in energy range 10-110keV. The interaction parameters for selected samples have been computed and provided in the extended energy range 0.015-15MeV. © 2014 Elsevier Ltd.

G-P fitting method has been used to compute buildup factors of some low atomic number (Z) silicates for the wide energy range (0.015-15.0 MeV) up to the penetration depth of 40 mean free path. The variation of buildup factors with equivalent atomic numbers, penetration depth and incident photon energies for the selected samples has been studied. Among the observations was the inverse relationship between values of buildup factors and equivalent atomic numbers for all samples. It has been concluded that the sample with least equivalent atomic number possesses the maximum value of buildup factor. It has been verified that datolite and diopside can be used as good shielding materials. The results have been depicted graphically with some useful conclusions. © 2011 Elsevier Ltd.

Highly crystalline ZnO nanoparticles (NPs) were synthesized with zinc acetate as precursor and oxalic acid at 80°C through the simple solution phase approach. The synthesized ZnO NPs possessed monodispersity with the average size 20-30 nm. The crystalline properties revealed the typical hexagonal wurtzite phase with orientation along c-axis. The photocatalytic activity investigation was carried out by performing the decomposition of rhodamine-B dye under UV illumination over as-synthesized ZnO NPs. The rhodamine B dye considerably degraded by ∼95 within 70 min in the presence of as-synthesized ZnO NPs. An excellent rate constant (k=0.0343 min-1) was obtained for the degradation of rhodamine B dye. © 2012 Elsevier B.V. All rights reserved.

In this paper a screen-printing method has been employed for the deposition of low zinc content cadmium zinc sulphide (Cd 0.9Zn 0.1S) composite thin films on ultra clean glass substrate. Cadmium sulphide, zinc sulphide and cadmium chloride have been used as the basic source material. With these basic source materials, the optimum conditions for preparing good quality screen-printed films have been found. X-ray diffraction studies revealed that the films are polycrystalline in nature, single phase exhibiting wurtzite (hexagonal) structure with strong preferential orientation of grains along the (1 0 1) direction. SEM/EDAX analysis confirms the formation of ternary compound. The optical band gap (E g) of the films has been studied by using reflection spectra in wavelength range 350-600 nm. The DC conductivity of the films has been measured in vacuum by a two probe technique. © 2011 Elsevier B.V.

Using the Lie symmetry approach, the authors have examined exact and numerical solutions of coupled short pulse equation with time-dependent coefficients. The method reduces the system of partial differential equations to a system of ordinary differential equations according to the Lie symmetry admitted. In particular, we found the relevant system of ordinary differential equations for all optimal subgroups. The system of ordinary differential equations is further studied in general to obtain exact and numerical solutions. Several new physically important families of exact and numerical solutions are derived. © 2014, Springer Science+Business Media Dordrecht.

Composites of polymer electrolyte polyethylene oxide (PEO) complexed with NH4ClO4, (PEO:NH4ClO4), having different weight ratios of dispersed semiconductor CuS (0-5 wt.%) have been prepared and characterized. The dispersal of CuS was achieved by its in situ formation in the viscous solution of polymer electrolyte (PEO:NH4ClO4) by sulfuration of CuSO4 using H2S. The band gap of CuS dispersed in the composites was found to be ~2.4 eV, which is higher than that of the bulk CuS for which it is 2.2 eV. Scanning electron microscopy studies show that the particle size varies from ~200 nm to several hundreds of nanometers. Polarization studies show that the semiconductor dispersed polymer composite so obtained has mixed ionic and electronic conduction. Detailed I-V studies show that the dispersoid is a p-type semiconductor. © 2010 Springer-Verlag.

To develop low cost and environment friendly technologies for removal of metal ions from water systems, graft copolymers based on guar gum and poly(N-Vinyl-2-Pyrrolidone) were synthesized. The optimum reaction conditions were evaluated for grafting by varying nature and amount of solvent, change in concentration of monomer and initiator, reaction time and temperature. Graft copolymers were characterized by FTIR, SEM, XRD, thermal analysis and swelling studies. Sorption of Fe2+ and Cr6+ ions on graft copolymers was investigated as a function of percent grafting, change in metal ion concentration and temperature to define their end-uses in separation technologies. © 2010 Elsevier Ltd.

Waste Management | Year: 2012

Various agricultural and kitchen waste residues were assessed for their ability to support the production of a complete cellulase system by Aspergillus niger NS-2 in solid state fermentation. Untreated as well as acid and base-pretreated substrates including corn cobs, carrot peelings, composite, grass, leaves, orange peelings, pineapple peelings, potato peelings, rice husk, sugarcane bagasse, saw dust, wheat bran, wheat straw, simply moistened with water, were found to be well suited for the organism's growth, producing good amounts of cellulases after 96. h without the supplementation of additional nutritional sources. Yields of cellulases were higher in alkali treated substrates as compared to acid treated and untreated substrates except in wheat bran. Of all the substrates tested, wheat bran appeared to be the best suited substrate producing appreciable yields of CMCase, FPase and β-glucosidase at the levels of 310, 17 and 33. U/g dry substrate respectively. An evaluation of various environmental parameters demonstrated that appreciable levels of cellulases could be produced over a wide range of temperatures (20-50 °C) and pH levels (3.0-8.0) with a 1:1.5 to 1:1.75 substrate to moisture ratio. © 2012 Elsevier Ltd.

Statistical analysis of a language is a vital part of natural language processing. In this paper, the statistical analysis of printed Hindi text is performed and then its comparison is done with the analysis already available with printed Punjabi text. Besides analysis of the characters frequency and word length analysis, a more useful unigram, bigram analysis is done. Miscellaneous analysis like Percentage occurrence of various grouped characters and number of distinct words and their coverage in Hindi and Punjabi Corpus is studied. © 2011 Springer-Verlag.

The gamma ray buildup factors for six silicate samples have been calculated, in the energy range of 0.015-15 MeV for penetration depths up to 100 mfp (mean free path), using five parameters based geometric progression (G-P) fitting formula with modified expression for dose multiplication factor [K(E, x)]. The computations were done using ANSI/ANS 6.4.3-1991 (American National Standard). The extrapolation to the buildup factors of the selected samples beyond 40 mfp and up to 100 mfp in this energy range are new to the available literature. Calculated buildup factors of water have been shown good agreement with the available standard data. The obtained results for all samples have been compared and verified by using WinXCom software and GEANT4 Monte Carlo simulations. © 2012 Elsevier Ltd. All rights reserved.
