Heavy rains causing a flood like situation affect the grains stored in godowns. To save the grains from floods, they have to be transferred to safer places. Historical flood layers derived using the remote sensing data can be helpful in determining the safe place for transferring the grains from the flood affected godowns. Analyzing of satellite data for determining the safer locations needs specialized skills and GIS software’s. To overcome this, a web based information system, capable of organizing, hosting, and sharing of the flood layers and other spatial datasets as open geospatial consortium compatible web processing services is needed. For transferring the grains, the management must have the existing stock information of the flood affected godown as well as stock information of the godown where the grains are planned to be shifted. Mobile application, capable of reporting the stock information along with the godown location and ground photographs can be an efficient solution to do so. This paper presents work on web processing services integrated with mobile application using open source technologies to identify suitable grain godowns location.

Value added flood products helps decision makers in an efficient relief and rescue operations. On time availability of flood products, may help decision makers, in early decision making. Indian monsoon causes floods in several Indian states at a time, every year. Mapping multiple states at a time needs lot of man power and expertise. Manual flood mapping process is a time consuming process. Automatic procedures, for delineating flood and generation of value added products from satellite images can reduce the critical time-span. In the present study, an attempt is made to automate the entire flood mapping chain. The prototype study, is demonstrated for the state of Assam and the modules developed are tested for the multiple flood events during the Brahmaputra floods of August–September, 2016. The modules are checked for each stage and their outputs are validated with those as derived from manual procedures. The study has demonstrated significant reduction in the turn out time for flood response, which is very important during rapid disaster response.

Vinod Kumar Gupta,Gaurav Sharma,Deepak Pathania,N.C. Kothiyal 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.21 No.1

A pectin zirconium (IV) selenotungstophosphate (Pc/ZSWP) nanocomposite was prepared via sol–gelmethod. The material was characterized using different techniques such as FTIR, SEM and TEM. Theadsorptional/photocatalytic activity of Pc/ZSWP was investigated for the removal of methylene blue andmalachite green dyes in two different conditions. It was revealed that the synergistic adsorptional/photocatalytic degradation of dyes was more efficient than mere adsorption in dark followed byphotocatalysis. The photocatalytic degradation percentage of MB and MG dyes onto Pc/ZSWPnanocomposite was found out to be 89.21 and 79.27% in 3 h of photo irradiation which is higherthan for adsorption in dark followed by photocatalysis. The antimicrobial activity of Pc/ZSWP was alsoascertained against Escherichia coli.

Tissue engineering is a research domain that deals with the growth of various kinds of tissues with the help of synthetic composites. With the culmination of nanotechnology and bioengineering, tissue engineering has emerged as an exciting domain. Recent literature describes its various applications in biomedical and biological sciences, such as facilitating the growth of tissue and organs, gene delivery, biosensor-based detection, etc. It deals with the development of biomimetics to repair, restore, maintain and amplify or strengthen several biological functions at the level of tissue and organs. Herein, the synthesis of nanocomposites based on polymers, along with their classification as conductive hydrogels and bioscaffolds, is comprehensively discussed. Furthermore, their implementation in numerous tissue engineering and regenerative medicine applications is also described. The limitations of tissue engineering are also discussed here. The present review highlights and summarizes the latest progress in the tissue engineering domain directed at functionalized nanomaterials.

Comparative Potential of Phenotypic, ISSR and SSR Markers for Characterization of Sesame (Sesamum indicum L.) Varieties from India

Vinod Kumar,Satyendra Nath Sharma 한국작물학회 2011 Journal of crop science and biotechnology Vol.14 No.3

The assessment of genetic diversity is a primary concern of plant breeders and germplasm curators for which morphological traits are internationally accepted descriptors but are often associated with limitations due to G x E interactions. Phenotypic, ISSR, and SSR markers were employed to determine the genetic diversity and relationships among 20 commercially cultivated sesame genotypes representing different geographical regions of India. A narrow range of genetic dissimilarity (0.01 - 0.12) with mixed clustering was observed using morphological descriptors. A total 279 band positions with 57% polymorphism was amplified by ISSR primers,whereas 36 allelic positions with 73% polymorphism were produced by SSR primers with 100% reproducibility. The ISSR primers with high discrimination power were identified producing genotype-specific bands and distinguishing all the sesame genotypes used in this study. A poor correlation and lack of perfect congruence between phenotypes and marker-based analysis was indicated by the UPGMA dendrogram and PCA analysis. Our results suggest that SSR and ISSR markers provide a powerful tool for genotype identification and establishment of genetic relationships among sesame genotypes. We recommend the use of molecular markers for testing,required for obtaining intellectual property rights, and also for the analysis of genotypic diversity among sesame varieties.

Mechanism and Regulation of Amino Acid Transport in Mammary Gland - Review -

Kansal, Vinod K.,Sharma, Rekha Asian Australasian Association of Animal Productio 2001 Animal Bioscience Vol.14 No.5

Several amino acid transport systems in mammary gland have been characterized during the last few years. These systems may be divided into two broad categories based on whether they are sodium-dependent or $Na^{+}$-independent, and each of these categories is subdivided into 3 groups depending on whether the systems prefer zwitterionic, cationic or anionic substrates. The zwitterion preferring transport processes in mammary gland are $Na^{+}$-dependent system A and $Na^{+}$-independent systems L and T. System $y^{+}$ is a $Na^{+}$-independent transporter of cationic amino acids and $X_{AG^{-}}$ is a $Na^{+}$-dependent system for anionic amino acids. A ($Na^{+}+Cl^{-}$)-dependent system, selective for $\beta$-amino acids has been reported in rat mammary tissue. In addition, there is yet another class of transporters that have still broader specificity. The $Na^{+}$-dependent systems $BCl^{-}$-dependent and $BCl^{-}$-independent and $Na^{+}$-independent system $y^{+}L$ have been reported to mediate the transport of zwitterionic as well as cationic amino acids. Each system has been characterized with respect to its substrate specificity, affinity, kinetics and ion-dependence. Transport of amino acids by mammary tissue is regulated by i) the intracellular substrate concentration, ii) lactogenic hormones and iii) milk stasis. Four of the above transport systems (i.e. A, L, $y^{+}$ and $BCl^{-}$-independent) are up-regulated by lactogenic hormones (insulin, cortisol and prolactin) in mammary gland.

The synthesized NPs were characterized by using FTIR, TEM, DLS, XRD, EDS and UV-Vis spectroscopy. The resulting Ag NPs had an incomparable colloidal stability against the salt addition and change of pH. The effect of different synthesis parameters and the catalytic property of the NPs were examined.

A Simple and Non-destructive Method of Direct-PCR for Plant Systems

R. Sharma,Vinod Kumar,T. Mohapatra,Vikas Khandelwal,Govind K. Vyas 한국식물학회 2012 Journal of Plant Biology Vol.55 No.2

To date, PCR is a fundamental tool for most of the research concerning plant diversity analysis, marker-assisted selection, genetic purity testing, disease diagnostics, and transgene analysis. In all of these analyses, good-quality DNA serves as a template for amplification of target sequences. Extraction of good-quality DNA requires many steps, making the whole process time consuming, tedious,labor intensive, and expensive due to costlier and toxic chemicals. To overcome these preparatory steps from PCRbased DNA amplification, we have developed a direct-PCR amplification method for plants without isolating DNA. The method is unique and beneficial over some previously described methods of direct-PCR which fail due to inefficient amplification of target DNA in the presence of PCR inhibitors and crop specificity. Moreover, such methods are non-specific and, being destructive, cannot be replicated; one cannot completely rely on them due to lack of reproducibility. This method was streamlined from our earlier observation that alcohol-desiccated tissues maintain intact DNA for a long time. This method is specific, rapid, and, being nondestructive,allows replication, giving advantages over existing methods. The method was tested over a wide range of plant species and found very effective and quick in generating data. The method was successfully used to test the genetic purity of pearl millet hybrid (RHB-127) and its restorer (RIB 3135-18) and CMS line (ICMA 93333A). Our method is especially important for developing inexpensive and high-throughput non-invasive genetic analyses.
