Migration of a Research Library's ICT-Based Services to a Cloud Platform

Libraries have been at the forefront in adopting emerging technologies to manage the library’s operations and provide information services to the user community they serve. With the emergence of cloud computing (CC) technology, libraries are exploring and adopting CC service models to make their own services more efficient, reliable, secure, scalable, and cost-effective. In this article, the authors share their experience migrating some of the library’s locally hosted ICT-based services onto the Microsoft Azure cloud platform. The migration of services to a cloud platform has helped the library significantly reduce the downtime of its services due to power or network or system outages

Use of Open-Source Software and Cloud Computing Technology for Imparting Training

The Department of Posts, Government of India, to date, has set up six full-time postal training centres (PTC) across India to meet the training requirements of its five-lakh strong workforce. PTC Madurai (PTCM), situated in Tamil Nadu, is one such training centre. PTCM has taken a proactive initiative to explore and adopt information technologies in the training and learning domains. It has partnered with the JRD Tata Memorial Library, Indian Institute of Science, Bangalore, through a small project to set up a digital infrastructure to manage its training programmes and the library collection. PTCM was looking for a digital library to manage its training materials, an online catalogue for its library collection, and a website. The consultants used three different open-source software to implement the requirements of PTCM viz; EPrints[1] for developing the digital library, Koha[2] for the integrated library management system, and WordPress[3] content management system for developing the website.

Crystal and molecular structure of muga wild silk fibres based on [Ala-Gly]n sequence using LALS technique

X-ray diffraction pattern of muga wild silk fibres has been recorded using imaging plate system (Dip-100S). In order to identify various Bragg reflections and to compute X-ray intensities of these reflections, fibre processing software (CCP13) has been used. A molecular model is first constructed with standard bond lengths and angles using helical symmetry and layer-line spacing observed in the X-ray pattern. The model is then refined against observed X-ray data using linked atom least squares method. The crystal and molecular structure of muga wild silk fibres are compared with reported domestic and wild silk fibre. We could get good R–factor with refinement of a model having beta-pleated sheet structures formed by hydrogen bonds having antipolar – antiparallel arrangement

Oxidative decolorization of indigo caramine dye with chloramine-T catalyzed by cobalt(II)

Decolorization of indigo caramine dye by oxidation process using chloramine-T as oxidant and Co(II) as catalyst in acidic buffer media, pH 5.8 has been kinetically studied at 300 K. Decolorization of indigo caramine dye was followed spectrophotometrically. Decolorization and oxidation led to a decrease in Chemical Oxygen Demand of the dye. The Co(II)-catalyzed reaction shows first-order dependence of the rate on chloramine-T and indigo caramine concentrations. It also shows fractional order dependence on Co(II)] and H(+)]. Addition of halide ions or reduction product of chloramine-T toluenesulfonamide, and variation of ionic strength and dielectric constant of the medium do not have any significant effect on the reaction rate. Activation parameters are evaluated from the Arrhenius plot, and a mechanism is proposed for the reaction

Hydrothermal coating of ZnO onto calcium alumino silicate beads and their application in photodegradation of amaranth dye

Hydrothermal coating of ZnO nanoparticles onto the surface of calcium alumino silicate beads was carried out under hydrothermal conditions (T, 220 degrees C; P, 300 psi; duration, 12 h). The reagent grade ZnO and calcium alumino silicate beads (0.5-1.0 mm in diameter, specially prepared as supporting material for ZnO) were used as starting materials along with 1M NaOH as a mineraliser leading to the formation of a new class of photocatalytic material. The effect of the hydrothermal experimental parameters on the coating of ZnO nanoparticles, and the grain morphology, etc. was investigated and thus obtained ZnO coated calcium alumino silicate beads were characterised using X-ray diffraction, SEM, Fourier transform infrared and positron annihilation spectroscopy. Sunlight and ultraviolet light mediated photocatalytic degradation of amaranth dye was studied using hydrothermally prepared ZnO coated calcium alumino silicate beads. The effect of various parameters such as initial dye concentration, catalytic loading, pH of the medium, time duration and light source on the photodegradation of amaranth dye was investigated. Silk industrial effluents containing amaranth dye as a major constituent along with other dyes and dyeing auxiliaries were treated using ZnO coated calcium alumino silicate beads

Hydrothermal synthesis and characterisation of tin doped ZnO polyscale crystals with hexylamine additive

Polyscale crystalline ZnO particles doped with tin were synthesised under mild hydrothermal conditions (T, 150°C; P, autogeneous; experimental duration, 16 h) in the presence of hexylamine as an additive. The resultant products synthesised were characterised using powder X-ray diffraction, Fourier transform infrared, scanning electron microscopy, measurement of zeta potential and dynamic light scattering. The characterisation results indicated better morphology, particle size distribution and low agglomeration of the polyscale crystals synthesised in the presence of hexylamine additive. The photodegradation of brilliant blue dye using these metal oxide polyscale crystals was investigated under sun light and ultraviolet irradiation. The degradation of the dye was checked using the following parameters: chemical oxygen demand and percentage transmission (%T). The photodegradation results showed that the tin doped ZnO polyscale crystals with hexylamine additive had higher efficiency compared to the reagent grade ZnO in photodegradation of brilliant blue dye
