Genetic relation in Capcicum annum [L.] cultivars through microsatellite markers: SSR and ISSR
Avni S Patel, Sasidharan N., Ashish G Vala and Vinay kumar
Electronic Journal of Plant Breeding , 2011,
Abstract: Capsicum annum [L.] is one of the most economically important vegetable crops in India. In order to assess the genetic relation,DNA from thirteen capsicum cultivars were screened using inter simple sequence repeat (ISSR) and microsatellite (SSR)markers. Five ISSR primers amplified 204 reproducible bands of which 139 were polymorphic. The percentage of polymorphicbands detected by ISSR was 100%. The highest polymorphic bands obtained by the use of primers UBC-809 (34) and UBC-66(53). A total of 1-5 alleles were detected by six SSR primers, with an average of two alleles per primer. The number of alleles perlocus ranged one (ssrCAMS-811) to five (ssrCAMS-142). The polymorphism information content (PIC) values ranged from 0.27(ssrCAMS-405) to 0.67 (ssrCAMS - 142). This study reveals the great importance of guaranteeing the differentiation of chillicultivars and the application for certification purposes
Cytological causes of blond psyllium for male sterility
Ashish G. Vala, Fougat. R.S. ,Roshni.S. and Vinay Kumar
Electronic Journal of Plant Breeding , 2011,
Abstract: Cytological male sterility is a useful trait in plant breeding, especially in medicinal plants such as Cassia angustifolia, Commiphorawightii, Asparagus racemosus .Abnormalities appeared to be the cause of male sterility in plants, we carried out this research in anattempt to make clear the characteristics and inheritance of this male sterility. In Plantago ovata germplasm cytoplasmicabnormality was found to be the cause of abnormality. cytomixis varied from 2% to 48 % in plants. Maximum numbers of PMCscarrying B-chromosomes were recorded in male sterile plants of line JI-214(62%). No B-chromosomes were observed in fertile,sterile and partial male sterile line of JI-107 and maximum abnormal chromosomal segregation was recorded in JI-206. Thesecytological abnormality parameters can be used for hetrosis breeding and hybrid seed production to improve quality of psyllium.

Korada Hari Venkata Durga Rao,Vala Venkateshwar Rao,Vinay Kumar Dadhwal,Gandarbha Behera,Jaswant Raj Sharma
International Journal of Disaster Risk Science , 2011, DOI: 10.1007/s13753-011-0014-7
Abstract: Hydrological modelling of large river catchments has become a challenging task for water resources engineers due to its complexity in collecting and handling of both spatial and non-spatial data such as rainfall, gauge-discharge data, and topographic and hydraulic parameters. In this article, a flood forecast model is developed for the Godavari Basin, India through a distributed modelling approach using space inputs. The approach includes rainfall runoff modelling, hydrodynamic flow routing, calibration, and validation of the model with field discharge data. The study basin is divided into 128 subbasins to improve the model accuracy. Topographic and hydraulic parameters of each subbasin and channel are computed using the land use / land cover grid that is derived from the Indian Remote Sensing Satellite (IRS-P6) AWiFS sensor data (56 m resolution), Shuttled Radar Topographic Mission (SRTM) Digital Elevation Model (DEM), and the soil textural grid. The model is calibrated using the field hydrometeorological data of 2000 and validated with the data of 2001. The model was tested during the 2010 floods with real-time 3-hour interval hydrometeorological and daily evapotranspiration data. Accuracy in estimating the peak flood discharge and lag time was found to be very good. Flood forecast lead time is increased by 12 hours compared to conventional methods of forecasting.

Ashish G Vala1*, R.S.Fougat1 and G.C.Jadeja
Electronic Journal of Plant Breeding , 2011,
Abstract: Genetic variability of 15 sets of Plantago ovata Forsk. studied using 11 arbitrary oligonucleotide primers. Among the 90 DNAfragments produced 71 fragments were found to be polymorphic. The mean number of polymorphic bands per primer among 15Plantago ovata genotypes was 6.45 . The higher polymorphism (90.00 %) was exhibited by primer OPF-17, while the lowerpolymorphism (60.00 %) was detected by OPF-2. The genetic similarity matrix from RAPD data for 15 genotypes was calculatedbased on Jaccard’s coefficients of similarity ranged from 0.45 to 0.80. UPGMA cluster analysis reveals that the 15 genotypeswere clustered in to three clusters. Genetically distinct genotypes identified using RAPD markers could be potential sources ofgermplasm for Isabgol improvement.

Vinay Satish Kumar, James G Ferry, Costas D Maranas
BMC Systems Biology , 2011, DOI: 10.1186/1752-0509-5-28
Abstract: The generated model iVS941 accounts for 941 genes, 705 reactions and 708 metabolites. The model achieves 93.3% prediction agreement with in vivo growth data across different substrates and multiple gene deletions. The model also correctly recapitulates metabolic pathway usage patterns of M. acetivorans such as the indispensability of flux through methanogenesis for growth on acetate and methanol and the unique biochemical characteristics under growth on carbon monoxide.Based on the size of the genome-scale metabolic reconstruction and extent of validated predictions this model represents the most comprehensive up-to-date effort to catalogue methanogenic metabolism. The reconstructed model is available in spreadsheet and SBML formats to enable dissemination.Genome-scale metabolic models (for recent reviews, see [1] and [2]]) are increasingly becoming available for an expanding range of organisms. There exists at least forty completed bacterial and thirteen eukaryotic metabolic reconstructions with many more under development [1]. In the past decade, several studies [3] have demonstrated a variety of uses ranging from strain optimization [4-6] pathogen drug target identification [7,8], bacterial community metabolic interactions [9] and identification of human disease biomarkers [10]. In contrast to the extensive interest devoted towards bacterial and eukaryotic metabolism reconstruction, efforts to construct archaeal metabolic models have been noticeably limited [11,12]. This is partly due to the current relative paucity of -omics datasets available for species from the Archaea domain. This dearth of data, however, is likely to change in the near future as recent interest in methanogenic archaea has led to several sequencing efforts [13-15], as well as transcriptomic and proteomic analyses [16-20]. Furthermore, it is increasingly becoming apparent that archaeal metabolism has significant implications to the earth's climate [21] thus motivating the need to globally ass
Secure Cloud Storage with Multi Cloud Architecture
Kavitha G M,,Vinay Kumar A N,,Balasubrhamanya
International Journal of Innovative Technology and Exploring Engineering , 2013,
Abstract: The use of cloud computing has increased rapidly in many organizations. Cloud computing provides many benefits in terms of low cost and accessibility of data. Ensuring the security of cloud computing is a major factor in the cloud computing environment, as users often store sensitive information with cloud storage providers but these providers may be untrusted. Dealing with “single cloud” providers is predicted to become less popular with customers due to risks of service availability failure and the possibility of malicious insiders in the single cloud. A movement towards “multi-clouds”, or in other words interclouds or cloud-of-clouds has emerged recently. In this paper, we provide solutions for secure cloud storage in multi cloud based system. This work aims to promote the use of multi-clouds due to its ability to reduce security risks that affect the cloud computing user.
COMPARATIVE STUDY ON CLASSIFICATION OF ECG ARRHYTHMIA USING SINGLE CLASSIFIER AND ENSEMBLE OF CLASSIFIERS
VINAY K, HEMANTHA KUMAR G, PRIYADARSHINI T.S.
International Journal of Machine Intelligence , 2011,
Abstract: An electrocardiogram (ECG) is a bioelectrical signal which records the heart’s electrical activity versus time. The interpretation of ECG signal is an application of pattern recognition. The techniques used in this paper comprise: signal pre-processing, R peak detection, QRS reconstruction, RR interval detection, feature extraction and linear classifier model versus ensemble of classifier model. The processed signal source came from the Massachusetts Institute of Technology Beth Israel Hospital (MIT-BIH) arrhythmia database which was developed for research in cardiac electro-physiology. The results of recognition rates are compared to find a better structure for ECG classification. Among different classifier model, it was found that ensemble of classifier with DECORATE meta-learner model possessed the best performance with highest recognition rate of 90.36% for cardiac conditions and moderate level of agreement between computerized prediction and cardiologist interpretation. Based on this result, the method of using important ECG features plus a suitable ensemble of classifier model outperforms the single classifier model and which can increase the testing speed and the accuracy rate.
Impacted Maxillary Central Incisor With Dilaceration
Vinay Kumar Reddy K,Venkateswara Rao G,Jaya Kiran M
Indian Journal of Dental Advancements , 2011,
Abstract: Maxillary central incisor impactions occur infrequently. Their origins include various local causes, such as odontoma, supernumerary teeth, and space loss. Dilaceration is one of the causes of permanent maxillary incisor eruption failure. It is a developmental distortion of the form of a tooth that commonly occurs in permanent incisors as result of trauma to the primary predecessors whose apices lie close to the permanent tooth germ. A case of impacted maxillary left central incisor with dilaceration in a young patient is presented.
