    The main objective of this study is to look into the extent of coverage of birth registration in eastern Uttar Pradesh. Vital registration being an important source of demographic data for socio-economic, health and other related planning of a nation particularly at the micro levels, its recognition in terms of its coverage and its value to socio-economic planning cannot be underemphasized. The coverage of birth registration in eastern Uttar Pradesh has been found only 21 per cent-11 and 43 per cents respectively in rural and urban areas. Lack of knowledge about the procedure of birth registration, least interest among the people due to their thinking that there is no use of birth certificate(s), have been found to be some of the important reasons of low coverage of birth registration in the area under study. This study has tried to see the extent of birth registration, knowledge and attitude of masses about it and specific reasons for not getting momentum in birth registration in the region under study. Some ways and means by which the vital registration system can be strengthened in the country are also pointed out

    Begomovirus DNA replication and pathogenicity

    Get PDF
    Begomoviridae is the largest genus of the family of single stranded DNA plant viruses, Geminiviridae and is responsible for significant agro-economic losses worldwide. Its small single-stranded DNA genome primarily replicates by rolling circle replication (RCR) mode with the help of certain viral and host factors. The role of virus encoded Rep protein in initiation and immediate post-initiation phases of RCR has been the subject of various studies. We have identified many host proteins which interact with Rep protein of a member of Begomovirus, namely, Mungbean yellow mosaic India virus, thereby playing a role in viral DNA replication. Of these, the role of host RAD54 protein is significant as the rad54 mutant of Arabidopsis does not permit mini viral DNA replication. The plant hosts protect themselves from begomoviruses by activating RNA interference (RNAi) pathways targeted against the viruses. However, the virus can also sometime overcome this form of host defence by encoding RNA silencing suppressors, which attenuate host RNAi and are regarded as major pathogenicity determinants. The viral suppressors do not share any signature sequences and are structurally and mechanistically dissimilar. These can be detected effectively, only through specialized functional assays. In this review, we also point out the potential biotechnological applications of the suppressors and discuss about various possible containment strategies for begomoviruses, including an exciting new approach involving artificial micro- RNAs

    Approximation and Analysis of Single Band FIR Pass Integrator Centered around Mid-band Frequencies with Degree k = 1, 2, 3…

    In this paper, a modified Finite Impulse Response based linear Pass integrator for centered frequency, ranging between 0.1 π to 0.9 π has been realized. Both the cases have been considered i.e. for what values the phase response is of use and where the phase response has zero value. An iterative formula has been used to calculate the weights depending upon the Transfer Functions, and applying differentiation method. A flat output approximation for the desired frequency ω has been applied for which the results overlap with the ideal integrator. Performance comparison of the proposed integrator has been done with the previous one and relative percentage errors have been observed for both cases implemented. Graphical analysis has also been carried out for frequency responses having degree greater than one (i.e. k = 2, 3, 4) for both cases of proposed integrator and compared with the ideal integrator's response

    Bactericidal Efficacy of Allium sativum (garlic) Against Multidrug Resistant Vibrio cholerae O1 Epidemic Strains

    In recent years, emerging trend of antibiotic resistance in Vibrio cholerae associated with cholera epidemics is a matter of serious concern for the management of the disease. Indiscriminate use of antibiotics generally results in selection of antibiotic resistant strains. Introduction of newer antibiotics is a challenging task for the researchers as bacteria soon attain resistance. Therefore, identifying natural compounds of medicinal importance for control of cholera would be the best alternative. Garlic (Allium sativum) was recognised for many centuries in early Chinese, Egyptian and Indian civilisations as an herbal or traditional medicine. In present study, garlic was selected for screening of antimicrobial efficacy against V. cholerae. A total of 55 V. cholerae strains isolated from various outbreaks/epidemics were subjected to antimicrobial testing as per CLSI, USA 2010 guidelines. Antimicrobial screening of garlic extract was performed against all the multidrug resistant strains of V. cholerae. The garlic extracts showed antibacterial activity against all the V. cholerae strains tested, irrespective of their origin, multidrug resistance and virulence. Antibacterial efficacy of garlic on V. cholerae was also evident from in vivo study on sealed adult mice model. Thus, the Garlic extract harnesses the potential to control infection of multidrug resistant V. cholerae, especially in outbreak like situations in remote and under developed areas where drug supply itself is a challeng

    A New Approach of Colour Image Encryption Based on Henon like Chaotic Map

    In modern era of digital world, exchange of information in form of image often very frequently over communication channel, the secrecy of multimedia data like images becomes very important, The issue of secrecy for image resolved In many digital applications such as sensitive visual aids, broadcasting, military services, rare satellites images and confidential medical images etc. To reduce the processing overhead with the concern of Real-time data transmission application, to reduce such a huge file processing cost, we needs to enhance our encryption/decryption techniques. This paper proposed a novel image encryption technique based on Hannon like chaotic map. Chaos-based image encryption technique is one of the more promising encryption algorithms that provide very efficient and fast way of image encryption due to its ubiquitous phenomenon in deterministic nonlinear systems that exhibit extreme sensitivity to initial condition and random like behaviours. Keywords— Image RGB colour component, image encryption, Henon map, chaotic system

    ABSTRACT The present paper describes the development of rectenna in terms of its applications in Microwave Power Transmission, Harmonic Rejection, CP radiation and ISM band. These rectennas consist of several antennas such as dipole, antenna arrays, slot meander line and rhombic loop antennas along with the rectifying diodes. In some cases more than one rectifying devices have also been used and antenna is found to be act at dual bands. It has also found that rectenna reject the harmonics upto 3 rd order and enhanced the performance characteristics. The maximum efficiency about 91% with 1.2 W of input power has been observed if the rectenna is used for microwave transmission

    Nexus of Financial Inclusion and Economic Growth: Benchmarking the Performance of Indian States

    Get PDF
    The study evaluates and benchmarks the performance of Indian states considering the proposed multidimensional financial inclusion index (FII) as input and economic growth as an output variable. The HDI methodology of UNDP is adopted in the construction of supply and demand side FII for 27 Indian states for the period 2004 to 2017. The output-oriented DEA models are used in which supply and demand FIIs are used as an input and real gross state domestic product as an output to measure the technical efficiency of the states. The major findings of the study suggest Maharashtra performs at the frontier and benchmarks for all other states in both CRS and VRS DEA models which is consistent with FII indices of the states. Therefore, structural reforms are warranted in the policy framework to improve financial services in poor and low performing states to spur economic development

    Impact of Work Function Tunability on Thermal and RF Performance of P-type Window based Junctionless Transistor

    Get PDF
    The choice of gate metal technology for junctionless transistors needs to have diverse charac- teristics as metals have distinct work functions and hence, they show incompatibility while tailoring thresh- old of the device. In such a scenario, bimetallic stacked gate can be a promising candidate to present wide range of tunable work functions required for nano- regime junctionless transistors. This paper explores the electronic phenomena occurring at metal-metal inter- face and the impact of Platinum (Pt)/Titanium (Ti) bimetallic stacked gate-based work function tunabil- ity on the RF and thermal performances of p-type window-based Silicon on Insulator Junctionless Tran- sistor (SOI JLT) using numerical simulator SILVACO ATLAS. The parameters considered for performance evaluation are ON-state current (ION ), OFF-state cur- rent (IOF F ), ION /IOF F ratio, transconductance (gm), cutoff frequency (fT ), Transconductance Frequency Product (TFP), Intrinsic Gate Delay (IGD), intrin- sic gain (AV ), and Global Device Temperature (GDT). The gm, fT , TFP, AV and GDT improve for modi- fied over conventional in the ON state at higher work function, while IGD improves at lower work function. The improvements of 11.7 % and 2.21 % are obtained in maximum gm and fT , respectively, for modified tran- sistor over conventional. The findings suggest that bimetallic stacked gate modified SOIJLT is a better op- tion than conventional for low-power RF application

    Get PDF
    A modern Ritchey-Chretien Cassegrain 130-cm diameter optical telescope has been successfully installed at Devasthal, Nainital in the central Himalayan region. This location was chosen after carrying out extensive site surveys. The first images obtained with the telescope indicate that atmospheric seeing and sky darkness at Devasthal are nearly at values as measured during the site survey. The values of seeing and sky darkness are comparable to some of the best astronomical sites in the world. The 130-cm telescope is functional and observations can be carried out from the control centre at Devasthal or from the Manora Peak in Nainital. This telescope has started providing valuable data for a number of research projects and is expected to help meet part of the national requirement in optical observational astronomy from small-aperture ground-based telescopes
