Introduction and Aim: The investigation was carried out to separate bioactive constituent from Emblica officinalis fruit and to evaluate the memory enhancing activity of the isolated compound. Materials and Methods: Successive extraction of the plant was made using different non-polar to polar solvents to extract out active principles according to their solubility. Memory enhancing activity was confirmed using scopolamine and sodium nitrite induced memory deficits (amnesia), elevated plus-maze (EPM) and Morris water maze (MWM). Results: Memory deficits in male albino mice induced by scopolamine hydrochloride and sodium nitrite were recorded as transfer latency time (TLT) in EPM model; escape latency time (ELT) and time spent in the Q4 target quadrant (TSTQ) in MWM model. Scopolamine and sodium nitrite markedly decreased the TLT over 2 min, ELT, TSTQ over 90 sec and consecutively impaired learning and memory. Bioactivity-guided fractionation of the memory enhancing methanolic extract has led to the isolation of a bioactive polar compound. Structure elucidation of the compound by UV, IR, 1H NMR, 13C NMR, MS techniques indicated it being biphenyl dicarboxylic acid. Conclusion: The memory deficits were significantly reversed by the biphenyl dicarboxylic acid thus confirming its memory enhancing the effect. The biphenyl dicarboxylic acid was found to be responsible for memory enhancing activity of the plant.

In recent times electronic throttles are more and more important in automotive engines so as to achieve better fuel economy, minimum vehicle emission and good drivability. One of the major component inside an automobile engine is throttle valve. The control of electronic throttle is actually the control of movement of plate through which amount of air that enters to the combustion engine is controlled. In this paper, initially, a mathematical model is designed by considering the dynamical behavior of the electronic throttle and further transformed to a state space model. The controller is developed by employing the dynamic surface control (DSC) technique which has been derived from backstepping and sliding mode control techniques. With the help of the simulation results the effectiveness of the proposed controller are shown which prove the validity of the technique. © 2015 IEEE.

This research paper reports the utilization of gum xanthan-grafted-polyacrylic acid and Fe3O4 magnetic nanoparticles based nanocomposite hydrogel (NCH) for the highly effective adsorption of methyl violet (MV) from aqueous solution. Synthesized NCH was characterized using various techniques, such as FTIR, XRD, SEM-EDS, TEM and BET. Adsorption behavior of NCH was studied for the adsorption of MV and it was found to remove 99% dye from the solution. Adsorption process followed Langmuir isotherm model (qe=642mg/g) and pseudo-second-order kinetics model. Thermodynamic studies suggested that the adsorption process was endothermic and spontaneous. Moreover, the adsorbent was successfully utilized for successive five cycles of adsorption-desorption.

Polymer Degradation and Stability | Year: 2015

In the present work, biodegradation study of Gum tragacanth-acrylic acid based hydrogel was conducted using soil burial and composting methods. Within 77 days, complete degradation of synthesized hydrogel was observed in the composting method, while 92.29% of degradation was observed in soil burial method. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) techniques gave the evidence and progress of biodegradation at different stages. Impact of biodegradation of hydrogels on soil fertility was studied through macroanalysis of soil before and after biodegradation studies. Plant growth of Phaseolus vulgaris showed that test sample soil was better for plant growth in comparison to the garden soil. Synthesized hydrogel was also evaluated for controlled release of fertilizer. Fertilizer release kinetic through the synthesized matrix showed Non-fickian diffusion behaviour. © 2015 Elsevier Ltd.All rights reserved.

Polycyclic Aromatic Compounds | Year: 2015

Preliminary analysis was performed to assess contamination levels in roadside soils, distribution behavior and human exposure with Polycyclic Aromatic Hydrocarbons (PAHs) during summer, winter, rainy, and autumn during 2013 in one of the developing cities of northern India. The concentration of PAHs was measured at ten different locations (at 1, 2, and 3 m) from roadside soil. Recovery range was 30% and 80% with lower value corresponding to the lower molecular weight PAHs compound. Identification and quantification of PAHs was done by GC-FID. Average PAHs concentration (city average) was found to be 16.53, 4.04, 17.49, and 7.82 μg g−1, during summer, winter, autumn, and the rainy seasons, respectively. Average concentration of low and high carcinogenic PAHs during summer, winter, autumn, and rainy was 5.1 and 31.29, 2.1 and 6.4, 4.74 and 35.08, 3.97 and 12.77μg g−1, respectively. The average ratio of low and high carcinogenic PAHs was found to be 1:6, 1:3, 1:7.6, and 1:3.21 during summer, winter, autumn, and the rainy seasons at most intercepts. Dib(ah)A and B(a)P were the two individual PAHs found in highest concentration during summer, winter, and the rainy seasons, whereas B(a)P and IP were individual PAHs found in highest concentration during autumn. It was also analyzed that high carcinogenic PAHs concentration was quite higher (around 85%) in comparison to low carcinogenic PAHs (around 15%) at most intercepts. This article also deals with the behavior of PAHs at places of average/high population and traffic density intercepts. Five-ringed PAHs were in highest concentration at all intercepts and seasons. Two-tailed T test was applied for authenticity of the data and results. Toxic equivalency factor of B(a)P and Dib(ah)A was maximum as compared to other PAHs. 2015 Copyright © Taylor & Francis Group, LLC

CAPTCHA is widely research field become a ubiquitous defense to protect open web resources from automated access. The objective of CAPTCHA is to give genuine services to every user by minimize automated approaches. An efficient CAPTCHA must be not only human friendly, but also robust enough to resist to machine attacks for pass CAPTCHA test. Many CAPTCHAs have been proposed in literature like text-graphical based, video based, mathematical or questions based. The miscreants attempt to effectively bypass these CAPTCHA test by use optical recognition or machine learning techniques. The design and implementation of CAPTCHA lie in the domain of artificial intelligence. We aim to design a CAPTCHA, which will effectively use by modern digitize world and turn to reduce the optical recognition and other automated attacks. In this paper, for better security issues, a non OCR CAPTCHA design called digital CAPTCHA based on Mathematical Boolean algebra by use digital logic gates. The different logic gates design which depict shapes like (AND, OR, NOT, NAND, NOR). Each gate executes multiple answers based on Boolean algebra by use Boolean laws. For prove human, user recognize shapes of logic gates and choose a correct answer from multiple answers. The experimental results analyze by multiple technical and non technical users with different age groups. The resulting values show that our proposed system has high probability and security and resists the visual attacks with existing math CAPTCHAs. © 2016 IEEE.

To maintain the secrecy of information, various information hiding techniques are used. Steganography is one of them, which means hide information inside another digital media like text, image, audio, video etc. without being detected by human visual system (HVS). Recently Video steganography has become a strong tool to hide large amount of data rather than image steganography. This paper is proposing an idea about a hybrid approach for video steganography to achieve high capacity data & high quality of stego video on the basis of quality metrics like PSNR, MSE and BER. The proposed methodology is a combo pack of various techniques such as RSA encryption, Edge detection, Identical Match and 4LSB substitution, in which a video file will be used to hide text message inside in all layers of RGB color frames of video. The experimental results are analyzed on MATLAB software on cover video of 'rhinos' and text secret message is embedding inside the video. The resulting values show that our proposed algorithm has high imperceptibility and security and resists the visual attacks. © 2016 IEEE.
