Betelvine(Piper betle L.) is cultivated for its deep green heart shaped leaf for(15-20) million Indian and 2 billion foreign consumers annually. The crop provides Rs(6 000-7 000) million of national income per year and at the same time leaves worth Rs(30-40) million is exported to other countries. The leaves are not only used directly for chewing purposes but also possesses antioxidant, anti-inflammatory, anti-apoptotic, anti-cancer and anti-microbial properties. Besides, the leaves also contain eugenol rich essential oil(1%-3%) which is the source for medicine, stimulant, antiseptic, tonic and other ayurvedic formulations. The essential oil also contains chavibetol, caryophyllene and methyl eugenol which are the potent source for preparation in ayurvedic medicine and herbal products. Cost of betelvine essential oil is 10$ per 5 mL. In spite of its great economical and medicinal importance betelvine is still neglected by the researchers for proper characterization and authentication for selection of elite landraces. Lack of awareness among people, use of same planting material for many generations, existing of many synonyms for a single landraces, no proper characterization of available landraces are some of the significant constraints for its commercialization. Our review endeavours a complete advance in the research on betelvine, existing lacunae for its proper characterization and commercial cultivation. It also attempts to provide a comprehensive account on biotechnological interventions made in betelvine aimed at complementing conventional programmes for improvement of this nutraceutically important cash crop.

Hydrodynamics of gas-solid fluidization of a homogeneous ternary mixture in a conical bed:Prediction of bed expansion and bed fluctuation ratios

引用

Particuology 2013年第6期11卷 681-688页

作者： D.T.K.Dora S.R.Panda Y.K.mohanty G.K.Roy Department of Chemical Engineering Gandhi Institute of Engineering and Technology(GIET) Department of Chemical Engineering National Institute of Technology(NIT)

Hydrodynamic characteristics of fluidization in a conical or tapered bed differ from those in a columnar bed because the superficial velocity in the bed varies in the axial direction. Fixed and fluidized regions could coexist and sharp variations in pressure drop could occur, thereby giving rise to a noticeable pressure drop-flow rate hysteresis loop under incipient fluidization conditions. To explore these unique properties, several experiments were carried out using homogeneous, well-mixed, ternary mixtures with three dif- ferent particle sizes at varying composition in gas-solid conical fluidized beds with varying cone angles. The hydrodynamic characteristics determined include the minimum fluidization velocity, bed fluctuation, and bed expansion ratios. The dependence of these quantities on average particle diameter, mass fraction of the fines in the mixture, initial static bed height, and cone angle is discussed. Based on dimensional analysis and factorial design, correlations are developed using the system parameters, i.e. geometry of the bed （cone angle）, particle diameter, initial static bed height, density of the solid, and superficial velocity of the fluidizing medium. Experimental values of minimum fluidization velocity, bed fluctuation, and bed expansion ratios were found to agree well with the developed correlations.

Development of a field enhanced photocatalytic device for biocide of coliform bacteria

引用

Journal of Environmental Sciences 2016年第6期28卷 38-44页

作者： Jeff M.Huber Krista L.Carlson Otakuye Conroy-Ben Mano Misra Swomitra K.mohanty Departments of Civil Engineering University of Utah Departments of Metallurgical Engineering University of Utah Departments of Chemical Engineering University of Utah

A field enhanced flow reactor using bias assisted photocatalysis was developed for bacterial disinfection in lab-synthesized and natural waters. The reactor provided complete inactivation of contaminated waters with flow rates of 50 mL/min. The device consisted of titanium dioxide nanotube arrays, with an externally applied bias of up to 6 V. Light intensity, applied voltage, background electrolytes and bacteria concentration were all found to impact the device performance. Complete inactivation of Escherichia coli W3110（- 8 × 10^3CFU/mL） occurred in 15 sec in the reactor irradiated at 25 mW/cm^2 with an applied voltage of 4 V in a 100 ppm NaCl solution. Real world testing was conducted using source water from Emigration Creek in Salt Lake City, Utah. Disinfection of natural creek water proved more challenging, providing complete bacterial inactivation after 25 sec at 6 V. A reduction in bactericidal efficacy was attributed to the presence of inorganic and organic species, as well as the increase in robustness of natural bacteria.

Testing the intraplate origin of mega-earthquakes at subduction margins

引用

Geoscience Frontiers 2012年第4期3卷 473-481页

作者： Prosanta K.Khan Partha Pratim Chakraborty G.Tarafder S.mohanty Department of Applied Geophysics Indian School of MinesDhanbadIndia Department of Geology University of DelhiDelhiIndia National Geophysical Research Institute HyderabudIndia Department of Applied Geology Indian School of MinesDhanbadIndia

The disastrous Mw 9.3 （seismic moment 1.0 × 10^30 dyn/cm） earthquake that struck northwest Sumatra on 26 December 2004 and triggered -30 m high tsunami has rejuvenated the quest for identi- fying the forcing behind subduction related earthquakes around the world. Studies reveal that the stron- gest part （elastic core） of the oceanic lithosphere lie between 20 and 60 km depth beneath the upper （- 7 km thick） crustal layer, and compressive stress of GPa order is required to fail the rock-layers within the core zone. Here we present evidences in favor of an intraplate origin of mega-earthquakes right within the strong core part （at the interface of semi-brittle and brittle zone）, and propose an alternate model exploring the flexing zone of the descending lithosphere as the nodal area for major stress accumulation. We believe that at high confining pressure and elevated temperature, unidirectional cyclic compressive stress loading in the flexing zone results in an increase of material yield strength through strain hardening, which transforms the rheology of the layer from semi-brittle to near-brittle state. The increased compres- sive stress field coupled with upward migration of the neutral surface （of zero stress fields） under non- coaxial deformation triggers shear crack. The growth of the shear crack is initially confined in the near-brittle domain, and propagates later through the more brittle crustal part of the descending oceanic lithosphere in the form of cataclastic failure,
