First time in the history of independent India, the Government of India, took up the initiative to launch a Nationwide Ranking framework to rank the educational institutions in the country. The National Institutional Ranking Framework (NIRF) was launched by MHRD on 29th September 2015 and ranking was announced on 4th April, 2016. The major role was played by UGC, AICTE, NBA and INFLIBNET in ranking of the institutions. This paper provides an overview and score (overall and Teaching, Learning & Resources) for Indian Rankings 2016 including various challenges and opportunities for improvement in the next interaction of the NIRF implementation. The purpose of this paper to spread the awareness of such initiatives among academic communities. © 2016 IEEE.

In this paper we have shown that a finite acoustic mismatch between structure and barrier materials in low-dimensional structures leads to the acoustic phonon confinement, which in its turn brings about a corresponding decrease of the phonon groups velocity and modification of the phonon density of states. These factors contribute to the reduction of the in-plane lattice thermal conductivity, thus allowing one to increase the thermoelectric figure of merit. Results of experimental study of confined acoustic phonons in single Si thin films and Si/Ge superlattices are also reported High-resolution Raman spectroscopy of ultra-thin silicon-oninsulator structures reveals multiple peaks in the spectral range from 50 cm-1 to 160 cm-1. The peak position are consistent with the theoretical predictions and indicate the confined nature of phonon transport in thin films and superlattices with a finite acoustic mismatch between layers. This opens up a novel tuning capability for optimization of the thermoelectric properties of lowdimensional structures. © 2015 AIP Publishing LLC.

Biomolecules found in plants such as enzymes/proteins, amino acids, polysaccharides, and vitamins induce formation of nanoparticles. In this study, plant broth of Phyllanthus amarus containing a number of secondary metabolites was selected for the formation of silver nanoparticles (AgNPs) at room temperature. The UV-visible spectrum of the aqueous medium containing silver ions demonstrated a peak at 425,356 nm corresponding to the plasmon absorbance of silver nanoparticles. High-resolution transmission electron microscopy (HRTEM) showed the formation of well-dispersed silver nanoparticles in the range of 10-20 nm. The X-ray diffraction (XRD) spectrum of the AgNPS exhibited 2θ values corresponding to the silver nanocrystal. Copyright © Taylor & Francis Group, LLC.

EPA has classified inorganic Arsenic (as) as a Group A, human carcinogen. Along with water and soil as also entered into the food chain prominently around the Gangetic belt of Bangladesh and India thus, posing threat on the exposed population. Therefore, the study was undertaken to investigate the entry of as in food materials along the levee of river Ganges in Bihar (India). Water samples were collected from Hand Tube Wells, soil and four representative food samples Wheat, Rice, Pulse and Maize, from the agricultural land. A standard Silver Diethyle Dithio Carbamate (SDDC) method was adopted to analyze the samples for as using Thermo (UV-1) Spectrophotometer. Per capita consumption of water through drinking and cooking sources was also calculated. Water samples were highly intoxicated with a mean value of 0.141mg/l (n=20). The mean value of as in soil was 0.027mg/kg (n=6). All food samples were as positive. Wheat recorded the maximum (0.024mg/kg) and the minimum was in maize (0.011mg/kg). These local food crops provide the majority of the nutritional intake of the people in this area. Poor nutrition and dependency on these contaminated water and food sources are therefore of great importance to their overall health. © IDOSI Publications, 2011.

Human and Ecological Risk Assessment | Year: 2012

Health risk assessment due to groundwater As contamination was conducted in two As-prone panchayats, Rampur Diara (RD) and Haldichapra (HC) of the Maner block of the Patna district, Bihar (India). All 100% of the water samples surveyed were found to be contaminated with As with a mean value of 52 μg/L (n = 10) in RD and 231 μg/L (n = 10) in HC, both exceeding the World Health Organization (WHO) guideline of 10 μg/L and the Bureau of Indian Standards (BIS) standard of 50 μg/L, respectively. The average calculated per capita consumption of As through drinking water in RD ranged from 120 μg/day for 5-10-year-old children to 320 μg/day for adults older than 41 years, while in HC the average calculated As through consumption ranged from 580 μg/day for 5-10-year-old children to 1470 μg/day for adults older than 41 years. Hazard quotients were calculated to be between 12.1 to 41.6 for the RD population and 58.3 to 192.5 for the HC population, both exceeding the typical toxic risk index 1. In addition, cancer risk of 19 per 1000 was found for RD children and 87 per 1000 for HC children. Visible symptoms of Arsenicosis were also observed in the area. © 2012 Copyright Taylor and Francis Group, LLC.

We present a simple and eco-friendly biosynthesis of silver nanoparticles using Pomegranate peel extract as the reducing agent. Peel extract of Pomegranate was challenged with silver nitrate (AgNO3) and chloroauric acid (HAuCl4) solution for the production of silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs), respectively. The reaction process was simple for the formation of highly stable silver and gold nanoparticles at room temperature by using the biowaste of the fruit. The morphology and crystalline phase of the NPs were determined from UV-Vis spectroscopy, transmission electron microscopy (TEM), selected area electron diffraction (SAED) and X-ray diffraction (XRD) spectra. TEM studies showed that the average particle size of silver nanoparticles were 5 ±1.5 nm whereas the gold nanoparticles were found to be 10 ±1.5 nm. An effort has been also been made to understand the possible involved mechanism for the biosynthesis of the NPs. Presumably biosynthetic products or reduced cofactors play an important role in the reduction of respective salts to nanoparticles. © 2012 VBRI Press.

This paper proposes a feedback linearization scheme for performance improvement of induction motor drive. This scheme decouples the rotor flux and the torque using P-I controllers with feedback linearization scheme. The control scheme is implemented in a stationary reference frame. P-I controllers for speed and flux loop are systematically designed. To reduce torque ripple and to improve torque and speed responses fuzzy torque compensator is designed with 16 fuzzy rules. The control scheme is simulated in SIMULINK environment and implemented in RTDS environment. Proposed scheme with P-I controllers and with fuzzy torque compensator are compared. Simulation results are validated with RTDS test results. © 2012 Praise Worthy Prize S.r.l. - All rights reserved.

Plants respond to heavy metal stress by metal complexation process like production of phytochelations or by other metal chelating peptides. In this paper we report the synthesis of silver nanoparticles (AgNPs) from the room dried stem and root of Ocimum sanctum. The broth of the plant is used as a reducing agent for the synthesis of Ag nanoparticles at room temperature. The reaction process was simple and was monitored by ultraviolet-visible spectroscopy (UV-vis). There was formation of highly stable silver nanoparticles in the solution. The morphology and crystalline phase of the NPs were determined from transmission electron microscopy (TEM), selected area electron diffraction (SAED) and X-ray diffraction (XRD) spectra. Transmission Electron Microscopy studies showed that the silver nanoparticles obtained from roots and stem were of sizes 10 ± 2 and 5 ± 1.5nm, respectively. The various phytochemicals present within the ocimum plant result in effective reduction of silver salts to nanoparticles but their chemical framework is also effective at wrapping around the nanoparticles to provide excellent robustness against agglomeration. © 2010 Elsevier B.V.

Workshops are important components of the quadrennial ICTAC conferences. A workshop on 'Challenges in Education in Thermal Analysis and Calorimetry' was organized during ICTAC-15 as part of the activities of the ICTAC's Education Committee which works with the aim of promoting education and training in thermal analysis and Calorimetry. The identification of compounds based on their decomposition temperatures similarly to the identification of species based on chromatographic retention data or IR/Raman spectra has long been desired by thermoanalysts. Unfortunately, reactions in the solid phase take place in several elementary steps. As it is well understood from the practice, the shape of thermoanalytical curves depends almost exclusively.

Effect of seasonal changes on the life cycle of multivoltine KA × NB hybrid of Bombyx mori was studied. The insects were fed on different varieties of mulberry leaves but kanva-2 variety of Morus indica was best amongst all. In rainy season, B. mori male had a life span of 44.35 days while female of 45.95 days. In winter life span for male was 59.80 days and for female 60.75 days. The life span in summer was 46.48 and 47.70 days for male and female, respectively. Seasonal differences in the life span of B.mori indicated that moderate upper and lower limits of temperature, higher relative humidity, greater number of cloudy days and total rain fall were more optimal for tissue growth and egg production.
