        Genetic divergence and selection indices among the micromutant lines in blackgram [Vigna mungo (L.) Hepper]

        Senapati, Niranjan,Misra, Rama Chandra 한국작물학회 2009 Journal of crop science and biotechnology Vol.12 No.2

        Forty five micromutant lines of blackgram variety PU-30, developed by single and combination treatments with Gamma-rays, ethyl methane sulphonate (EMS), N-methyl-N- nitroso guanidine (NG) and maleic hydrazide (MH) were evaluated for yield and component traits. The mutant lines showed significant differences in all 9 traits indicating that the different mutagenic treatments were effective in inducing changes in all the quantitative characters, though magnitude, direction and frequency of changes varied with treatments. Genetic divergence among the mutants and the parent was estimated by $D^2$ analysis. 100-seed weight, plant height and pod length had high contribution to genetic divergence indicating induction of more micromutations in these traits. The genetic diversity $D^2$ estimates among the 45 mutant lines and the parent were significant indicating the effectiveness of mutagenic treatments in isolation of mutant lines with diverse changes in multivariate traits from the parent. Using Tocher's method the mutants grouped in to 11 diverse genetic clusters. 31 of the 45 mutant lines grouped into 10 different clusters away from the parent. These lines not only exhibited genetic diversity from the parent but also among themselves. The mutant lines derived from the same mutagenic treatment often grouped into different clusters indicating that there was no mutagen specific trend in clustering. On the basis of $D^2$ values and character complementation, hybridization of mutant line PM 3-3 with PN 3-2 or PGN 2-2 is expected to produce promising and desirable segregants in subsequent generations. The use of index selection on multiple traits including yield proved to be an effective and efficient method for selection of high yielding productive mutant lines such as PE2-3, PGN 2-3, PGN 2-2, PGM 2-2, PG2-1 and PG 3-2. These productive mutants showed changes in some growth and productivity traits from the parent variety and had 38.5 to 28.7 % yield superiority over parent. Three of these six mutants were derived from combined treatments and other three from single treatment with Gamma-rays or EMS.

        Enantioselective Synthesis of β-Iodo Morita–Baylis–Hillman Esters by a Catalytic Asymmetric Three-Component Coupling Reaction

        Senapati, Bidyut Kumar,Hwang, Geum-Sook,Lee, Sungil,Ryu, Do Hyun WILEY-VCH Verlag 2009 Angewandte Chemie Vol.48 No.24

        <P>A catalytic route toward chiral Morita–Baylis–Hillman esters by asymmetric coupling between α,β-acetylenic esters, aldehydes, and trimethylsilyl iodide has been developed (see scheme). The reaction proceeds with high to excellent enantioselectivities, and the products can be transformed into β-branched derivatives in a single step and with excellent retention of configuration.

        An indicator-based approach to assess farm households’ vulnerability to climate change: evidence from Odisha, India

        Asis Kumar Senapati 대한공간정보학회 2020 Spatial Information Research Vol.28 No.2

        The study aims to assess farmers’ vulnerability to climate change using indicator based approach in order to highlight important factors such as demographic, social and health factors contributing to vulnerability of agriculture to climatic variability and climate change in both irrigated and rain-fed regions of the state. Vulnerability analysis was done using three different composite indices such as: Livelihood Vulnerability Index, Livelihood Vulnerability Index of the Intergovernmental Panel on Climate Change, and Livelihood Effect Index. Based on results, the study found that water component has the largest contribution to the vulnerability of the farmers’ community in Bolangir district where as the Natural disaster and climate vulnerability has the largest contribution to the vulnerability of the farmers’ community in Cuttack district. High exposure and a relatively low adaptive capacity are significant factors that cause the farm household to be more sensitive to climate variability and climate change.

      • Cancer Registration in India - Current Scenario and Future Perspectives

        Chatterjee, Sharmila,Chattopadhyay, Amit,Senapati, Surendra Nath,Samanta, Dipti Rani,Elliott, Leslie,Loomis, Dana,Mery, Lesly,Panigrahi, Pinaki Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.8

        Cancer registration, an important component of cancer surveillance, is essential to a unified, scientific and public health approach to cancer prevention and control. India has one of the highest cancer incidence and mortality rates in the world. A good surveillance system in the form of cancer registries is important for planning and evaluating cancer-control activities. Cancer registration in India was initiated in 1964 and expanded since 1982, through initiation of the National Cancer Registry Program (NCRP) by the Indian Council of Medical Research. NCRP currently has twenty-six population based registries and seven hospital based registries. Yet, Indian cancer registries, mostly in urban areas, cover less than 15% of the population. Other potential concerns about some Indian registries include accuracy and detail of information on cancer diagnosis, and timeliness in updating the registry databases. It is also important that necessary data collection related quality assurance measures be undertaken rigorously by the registries to ensure reliable and valid information availability. This paper reviews the current status of cancer registration in India and discusses some of the important pitfalls and issues related to cancer registration. Cancer registration in India should be complemented with a nationwide effort to foster systematic investigations of cancer patterns and trends by states, regions and sub populations and allow a continuous cycle of measurement, communication and action.

      • Hybrid Beam-forming Algorithms for Planar Adaptive Antenna Array

        Jibendu Sekhar Roy,Anupama Senapati 한국디지털융합학회 2016 IJICTDC Vol.1 No.1

        Adaptive smart antenna arrays are used for cellular communication. This paper presents a comparative study of beamforming techniques for adaptive smart antenna using hybrid algorithms like Simple Matrix Inversion with Recursive Least Square (SMI-RLS) and Least Mean Square with Recursive Least Square (LMS-RLS) algorithm. The results are compared on the basis of null depth and error plot for different signal –to-noise (SNR) values, ranging from high to low values of SNR for heavily faded case..
