    The experimental material consisted of two parents Gurjari (white backed plant hopper resistant) and Jaya (white backed plant hopper susceptible) and their F2 progeny. The purpose of the study was the identification of RAPD (Random Amplified Polymorphic DNA) marker for white backed plant hopper (WBPH) resistant gene. The RAPD analysis was done group wise as well as combined for the bulk segregant analysis (BSA). For the BSA, of the total 50 random primers surveyed, a single linked primer, OPA 08, was identified. This primer generated 8-bands, one of which, OPA08-7, was putatively linked to resistant gene as was evident by its presence in almost all the resistant bulks and vice-versa. This band had molecular weight equal to 1219.38 bp and was found in resistant parent, Gurjari, and in almost all the resistant bulks (the four susceptible bulks revealed absence of the same band) indicating the band OPA08-7 as a marker for WBPH resistance among the screened rice genotypes

    Development of a scalable generic platform for adaptive optics real time control

    Full text link
    The main objective of the present project is to explore the viability of an adaptive optics control system based exclusively on Field Programmable Gate Arrays (FPGAs), making strong use of their parallel processing capability. In an Adaptive Optics (AO) system, the generation of the Deformable Mirror (DM) control voltages from the Wavefront Sensor (WFS) measurements is usually through the multiplication of the wavefront slopes with a predetermined reconstructor matrix. The ability to access several hundred hard multipliers and memories concurrently in an FPGA allows performance far beyond that of a modern CPU or GPU for tasks with a well defined structure such as Adaptive Optics control. The target of the current project is to generate a signal for a real time wavefront correction, from the signals coming from a Wavefront Sensor, wherein the system would be flexible to accommodate all the current Wavefront Sensing techniques and also the different methods which are used for wavefront compensation. The system should also accommodate for different data transmission protocols (like Ethernet, USB, IEEE 1394 etc.) for transmitting data to and from the FPGA device, thus providing a more flexible platform for Adaptive Optics control. Preliminary simulation results for the formulation of the platform, and a design of a fully scalable slope computer is presented.Comment: Paper presented as part of SPIE ICOP 2015 Conference Proceeding

    Viscosity of High Energy Nuclear Fluids

    Get PDF
    Relativistic high energy heavy ion collision cross sections have been interpreted in terms of almost ideal liquid droplets of nuclear matter. The experimental low viscosity of these nuclear fluids have been of considerable recent quantum chromodynamic interest. The viscosity is here discussed in terms of the string fragmentation models wherein the temperature dependence of the nuclear fluid viscosity obeys the Vogel-Fulcher-Tammann law.Comment: 6 pages, ReVTeX 4 format, two figures, *.eps forma

    In vitro method for predicting the bioavailability of iron from Bathua (Chenopodium album) and Fenugreek (Trigonella foenum graecum) leaves in Indian cookies

    This study was considered to determine the nutritional composition and in vitro bioavailability of iron of the prepared food products. The in vitro bioavailability of iron was determined in fresh and dehydrated bathua (Chenopodium album) and methi (Trigonella foenum graecum) leaves (in the ratio of 1:1) and their based product i.e. Indian cookies (paratha and laddoo) by using thiocynate method at pH 1.35 and 7.5, using pepsin. At pH 1.35 the soluble iron and ionizable iron were higher than pH 7.5. when pH was increased from 1.35-7.5 there was decreasing trend soluble as well as ionizable iron contents. There was highly significant (F< 0.05) difference between the control and treatments of products indicating that the addition of 20% of fresh and dehydrated leaves of bathua and methi improved the overall acceptability of products. The total iron content was found 11.69mg/100g in paratha incorporated with fresh GLVs whereas in vitro bioavailability of iron was found 2.16mg/100g in paratha. The total iron content was found 15.16mg/100g in laddoo incorporated with dehydrated GLVs whereas in vitro bioavailability of iron was found 2.78mg/100g in laddoo

    Achievements and prospects of grass pea ( Lathyrus sativus L.) improvement for sustainable food production

    Get PDF
    Grass pea offers an attractive choice for sustainable food production, owing to its intrinsic properties including limited water requirement and drought tolerance. However, low productivity and the presence of a neurotoxin (ODAP) have posed major obstacles to its genetic improvement. Also, biotechnological investments remain limited and the genome is complex and not well understood. Strategies that allow identification of genotypes with reduced ODAP content, coupling of low ODAP content with enhanced yield, and effective seed detoxification methods merit immediate attention. Breeder-friendly genomic tools are being increasingly made available to improve the efficiency of breeding protocols. To this end, the application of next-generation sequencing has provided a means of leveraging the repertoire of genomic resources for this somewhat neglected crop. In this review, we describe progress achieved in Lathyrus genetic improvement. We also explore potential opportunities in Lathyrus research and identify urgent research needs

    Evaluation of prescription errors and polypharmacy practices in rural area at community pharmacy

    Get PDF
    Background: Prescription refers to a written request from physician to patient for compounding and dispensing of medicines. The prescription comprises detail information of patient, physician, and drugs, absence of these prescription parameters may harm the patient’s safety. Inappropriate practices like polypharmacy prescriptions must be avoided as this may lead to non-compliance.Methods: A cross section observational study was conducted at a community pharmacy from September to November 2019. Permission was taken from the registered pharmacist. Prescriptions were collected from the subjects who visited the pharmacy in rural area. A checklist was prepared including all the parameters and the prescriptions were analyzed through Microsoft excel.Results: Out of 2227 prescriptions collected, patient’s name, age and weight were not written in 10.57%, 78.41%, and 12.33% of prescriptions respectively. Physician’s name, designation and registration number were not mentioned in 18.50%, 21.14%, 29.51% prescriptions respectively. Date of issue was lacking in 12.33% prescriptions. It was found that 44.49% prescriptions were illegible. It was observed that 82.81% prescriptions possessed dosage form of drug and 32.15% dose in it. The study showed that 19.2% prescriptions were polypharmacy prescriptions.Conclusions: Prescription is an authoritative document between doctor and pharmacist therefore it needs to be precise, fastidious, and scrupulous, monitoring to identify causes, analyze errors and blemishes in the prescription. One or other parameters were lacking in every prescription. ‘Educate to medicate’ this indicates that sound knowledge is requiring to prescribe therapeutically efficacious and accurate medicines in prescription
