Introduction: Exposure to radiation is a hazard and precautions are necessary to limit it. This study was done to assess the knowledge of radiation and the attitude towards radio-protection among urology residents in India. Materials and Methods: A questionnaire was administered to assess the knowledge and attitude of urology residents who came from all over the country to attend a clinical meeting at Apollo Gleneagles Hospital, Kolkata, India. Results: All the respondents agreed to being exposed to radiation, with 78.2% using radiation in more than five cases a week. Only 65.2% always took some steps for radio-protection. Lead aprons and thyroid shields were the most common radiation protection devices used. None of the residents ever used lead gloves or protective eye glasses or dosimeters. An 82.6% felt that they did not have adequate knowledge, 85.4% of residents did not receive any formal classes regarding the risk of radiation, 21.7% either rarely or never moved out of the operating room when the radiation was being used, 42.4% did not know that the SI unit of the equivalent absorbed dose of radiation & 52.1% did not know about the amount of radiation delivered to an adult during a contrast enhanced CT scan of the abdomen. Conclusion: Results of the present study reveal that the urology residents of India lack knowledge about the risks of radiation exposure. Majority of them did not take necessary precautions to limit their exposure to radiation. © 2015 Journal of Clinical and Diagnostic Research. All rights reserved. Source

This paper present a comparison of theoretical SQNR Vs OSR performance of Higher order Delta Sigma modulator for audio signal with multibit quantizier and a framework for stability analysis of sigma Delta modulator is presented. The Stability of the modulator is examined by means of the NTF. A analysis is present by taking different modulator order with selection of different type of filters (Butterworth, Chebyshev) for design of NTF and based upon observation is made on signal to noise ratio, out of Band gain and max stable amplitude for DSM. © 2013 IEEE.

Automatic Modulation Classification (AMC) is the technique for classifying the modulation scheme of an intercepted and possibly noisy signal whose modulation scheme is unknown. Automatic modulation classification of the digital modulation type of a signal has been taking much interest in the communication areas. This is due to the advances in reconfigurable signal processing systems, especially for the application of software radio system. Ten Digitally modulated signals are considered. Channel conditions have been modeled by simulating AWGN and multipath Rayleigh fading effect. Seven key features have been used to develop the classifier. Higher order QAM signals such as 16QAM, 64QAM and 256 QAM are classified using higher order statistical parameters such as moments and cumulants. Feature based Decision tree and ANN classifier have been developed and their performances are compared under varying channel conditions for SNR as low as -5dB. © 2015 IEEE. Source

Newborn swapping, missing, mixing, and illegal adoption is a global challenge and to resolve this emerging issue very less research has been done. Most of the biometric systems are developed for adults and extremely few of them address the difficulty of newborn recognition. As they are the highly non cooperative users of biometrics the ear of newborn may be a perfect source of data for passive identification of newborn. This paper investigates a unique approach for the automatic recognition of newborn using 2D ear imaging. Our investigation develops a computationally effective and attractive solution to recognize newborn automatically. The proposed algorithm yields Rank-1 identification accuracy of 89.28% on a database of 210 subjects. © 2015 IEEE. Source

In the present study a series of new N4-(4-substituted benzylidene)-N1-([1,3,4]thiadiazino [6,5-b]indol-3-yl)semicarbazide (1-6), N4-([1,3,4]thiadiazino[6,5-b]indol-3-yl)-N1-(1-(4—substituted phenyl)ethylidene)semicarbazide (7-10), N4-([1,3,4]thiadiazino[6,5-b]indol-3-yl)-N1-((4-substituted phenyl)(phenyl)methylene) semicarbazide. (11-14) have been synthesized from isatin and thiosemicarbazide through multiple steps to meet structural necessities for the anticonvulsant activity. All the newly prepared compounds were characterized by spectral techniques like FT-IR, 1H and 13C NMR, EI-MS and elemental analysis. All the newly synthesized compounds were investigated for the anticonvulsant activity against maximal electroshock induced seizures (MES) and subcutaneous pentylenetetrazole (scPTZ) models and their neurotoxicity were also evaluated by rotarod test. The results obtained showed that 64% of the compounds showed protection in the MES test and 36% of the compounds showed protection in ScPTZ test. Some of the compounds also showed good activity after oral administration. Among the synthesized compounds, compound 14 was shown to be the most active compound showing activity at 100 and 300 mg/kg in MES and ScPTZ test with prolonged duration of action. In the present study, semicarbazones of hydroxy containing carbonyl compounds were depicted to be the potent molecule with low neurotoxicity and prolong duration of action on oral administration. The result of the present study may be used for the future development of novel anticonvulsants with broad spectrum of anticonvulsant activity. © 2016 Bentham Science Publishers. Source
