DEAVD-Data Encryption and Aggregation using Voronoi Diagram for Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are applied in environmental monitoring, military surveillance, etc., whereas these applications focuses on providing security for sensed data and the nodes are available for a long time. Hence, we propose DEAVD protocol for secure data exchange with limited usage of energy. The DEAVD protocol compresses data to reduces the energy consumption and implements an energy efficient encryption and decryption technique using voronoi diagram paradigm. Thus, there is an improvement in the proposed protocol with respect to security due to the concept adapted during data encryption and aggregation

Age of the Earliest Transgressive Event in the Krishna-Godavari Basin, India: Evidence from Dinoflagellate Cysts and Planktonic Foraminifera Biostratigraphy

A combined biostratigraphic study of dinoflagellate cysts and foraminifera was carried out on Early Cretaceous subsurface well cutting sediments from well A (DNG) (2800–2746 m depth) from the Krishna-Godavari Basin, India. The last appearance datum of marker species of dinoflagellate cysts and planktonic foraminifera was considered for the construction of the biostratigraphic framework. The study shows dominance of Early Cretaceous marker dinoflagellate cysts Cassiculosphaeridia magna, Cribroperidinium perforans, Hystrichodinium voigtii, Kleithriasphaeridium eoinodes, and planktonic foraminifera Hedbergella aptiana, Hedbergella mitra, Hedbergella praelippa, Hedbergella tardita, Microhedbergella miniglobularis and Hedbergella mitra species. In addition to this, the dinoflagellate cyst data were compared with the dinoflagellate biozones of Austral and Tethyan provinces. Based on earlier micropalaeontological records from the Krishna-Godavari Basin and the present study, a latest Barremian-early Aptian age has been determined for the earliest marine transgression in the Krishna-Godavari Basin. The early marine incursion during late Barremian-earliest Aptian in the Krishna-Godavari Basin compared to Albian age in Cauvery Basin suggests the opening of east coast from north to south.

The neutrons were generated from the T(d,n)4He reaction using Purnima neutron generator. The experiment was done by using the method of activation in combination with an off-line γ\documentclass[12pt]{minimal}\usepackage{amsmath}\usepackage{wasysym}\usepackage{amsfonts}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{mathrsfs}\usepackage{upgreek}\setlength{\oddsidemargin}{-69pt}\begin{document}$$\gamma$$\end{document}-ray spectrometry technique. The uncertainties and correlations for the reaction cross sections were estimated with the use of covariance analysis by considering the partial uncertainties in individual attributes. The measured reaction cross sections have been analyzed by comparing with the data available in EXFOR compilation, various files of evaluated data and theoretically calculated values from TALYS-1.9

Mn-Mediated Oxidative Radical Cyclization of 2-(azidomethyl) Phenyl Isocyanides with Carbazate: Access to Quinazoline-2-Carboxylates

Mn-TBHP mediated oxidative radical cyclization of 2-(azidomethyl)phenyl isocyanides using methyl carbazate has been described. This procedure is realized through a cascade radical addition and aromatization process with high atom economy to furnish various heterocyclic C2 diversified quinazoline-2-carboxylate derivatives

Optimization of Oxalic Acid Pre-Treatment and Enzymatic Saccharification in Typha latifolia for Production of Reducing Sugar

Background Plants with high biomass can be manipulated for their reducing sugar content which ultimately upon fermentation produces ethanol. This concept was used to enhance the production of reducing sugar from cattail (Typha latifolia) by oxalic acid (OAA) pre-treatment followed by enzymatic saccharification. Result The optimum condition of total reducing sugar released from OAA pre-treatment was found to be 22.32 mg/ml (OAA—1.2%; substrate concentration (SC)—6%; reaction time (RT)—20 min) using one variable at a time (OVAT). Enzymatic saccharification yielded 45.21 mg/ml of reducing sugar (substrate concentration (SC)—2.4%; enzymatic dosage—50 IU/g; pH 7.0; temp—50 °C) using response surface methodology (RSM). Conclusion We conclude that Typha can be used as a potential substrate for large-scale biofuel production, employing economical bioprocessing strategies

Solution Combustion Synthesis, Characterization, Photocatalytic Activity and Electrochemical Studies of Zr1.49 Gd 1.49 O5.21 (zirconium Gadolinium oxide) Nanoparticle

In this work, we are reporting the synthesis of zirconium gadolinium oxide nanoparticle by using solution combustion route using gadolinium nitrate, zirconyl nitrate as an oxidiser and ethylenediamine tetraaceticacid (EDTA) as fuel. The primary aim is to establish a facile solution combustion reaction to produce zirconium gadolinium oxide nanoparticle using zirconyl nitrate and EDTA as precursors for the first time and study of its photo catalytic activity against anionic and cationic dyes in presence of UV light.The PXRD data reveals the construction of pure Zr1.49 Gd 1.49 O5.21 nanoparticle with cubic phase having crystallite size∼18.36 nm. SEM images exhibit highly porous nature of the product. BET surface area analysis of Zr1.49 Gd 1.49 O5.21 nanoparticle shows relatively large surface area of 12.89 m2 g-1. Transmission electron microscopy exhibits identical particle size distribution with average particle sizes varying in the range of 20-100 nm. The band gap of 344.4 nm is calculated using the diffuse reflectance spectrum of Zr1.49Gd 1.49 O5.21. The photoluminescence spectrum of Zr1.49 Gd 1.49 O5.21 nanoparticle shows emission peak at 467.2 nm. The photodegradation of methylene blue (MB) using Zr1.49 Gd 1.49 O5.21 as photocatalyst showed 80 % of decolourisation in the presence of ultraviolet (UV) radiation. The electrochemical studies using cyclic voltametry revealed, significant increase in current density of Zr1.49 Gd 1.49 O5.21 electrode when compared with bare carbon electrode and the simultaneous increase in redox current for the Zr1.49 Gd 1.49 O5.21 electrodes with increasing scan rate from 10 mVs-1 to 90 mVs-1

Protective and Therapeutic Effects of Garlic and Tomato on Cadmium-Induced Neuropathology in Mice

Background : Heavy metals are natural components of the earth's crust and are considered as constant environmental pollutants since they cannot be degraded or destroyed easily. Cadmium (Cd) is present primarily in the ores of zinc, copper, or lead; the extraction and processing of which releases large quantities of cadmium into the atmosphere, hydrosphere, and soil thereby contaminating the human environment. The present study aimed to investigate the possible protective and therapeutic effects of garlic and tomato extract on cadmium-induced AChE activity, biochemical parameters along with the pathological changes in the brain tissue of mice. Methods Male Swiss albino mice (n = 40) were divided into several experimental (protective and therapeutic) groups and were given single dose of cadmium (6 mg/kg bw) with supplementation of garlic (100 mg/kg bw) and tomato (50 mg/kg bw) extract for 15 and 30 days under protective and therapeutic study. Results Cadmium-treated mice showed a significant decline in AChE (p < 0.01) level and total proteins (p < 0.0001) but a nonsignificant decrease in glycogen, cholesterol in the brain tissue activity as compared to control group. The histological study also showed degeneration in the form of vacuolation, congestion, hyperemia, lymphocytic infiltration, and edema in the brain (cortex and hippocampus) of Cd-treated mice. But the antioxidant-treated groups showed significant increment in AChE level and other biochemical parameters in the protective study. But there were significant variations in the therapeutic study, and this was also confirmed by the histological analysis of the brain. Both tomato and garlic administration showed more attenuation in the brain AChE activity, and it may be due to the strong antioxidant potential of their constituents. Conclusion We can conclude that cadmium exposure should be avoided as it causes neuropathological effects. But in daily life, it may not be possible, so we should regularly intake natural antioxidants which may neutralize the effects of heavy metals to some extent. Citation Statements: 2 0
