    The protein content in the muscles, liver and gonad of Ratrelliger kanagurta from Sakhri-Natye fish landing centre at Ratnagiri district coast was studies from Within Potential Fishing Zone (PFZ) and Outside PFZ. The protein study analyzed that winter and summer season. the protein content was increased in male muscle than female muscle, gonad and liver respectively within PFZ than outside PFZ. The protein contents in the body muscle, liver and gonad of Rastrelliger kanagurta (Cuvier) were investigated. The compositions varied seasonally in relation to reproductive cycle of the fish. The study also showed that protein was high in the muscles and gonads and in liver from within PFZ than outside PFZ in female and male

    Calcium, Aluminum-rich Inclusions (CAIs) were the first formed solids in our Solar System, with mineral assemblages reflecting the first phases predicted to condense out of a hot nebular gas of Solar composition. Geochemical, textural and crystallographic information in CAIs can be used to constrain the temperature, pressure, and composition (e.g., oxygen fugacity) of the gaseous reservoir(s) from which they formed, as well as any secondary (nebular and parent body) processes they underwent. Coordinated geochemical and textural analyses provide information on nebular conditions (i.e., astrophysical environments and dynamics of nebular gas reservoirs) in which these CAIs formed. In order to better understand the evolution of nebular reservoirs at the time of CAI formation, we analyzed a Type A, B and C CAI using Electron Probe Micro-Analyzer (EPMA) and Electron BackScatter Diffraction (EBSD) at NASA Johnson Space Center (JSC)

    Snake Bite Complicated By Bacterial Meningitis

    Background: Neurotoxic snake bite envenomation is a common life threatening medical emergency in India, especially in the rural areas. Case Presentation: We report a case of a neurotoxic snake envenomation presenting with abdominal pain and neuromuscular paralysis, which developed bacterial meningitis during her stay in the hospital. Possibly, secondary to the snake bite, a very rare incidence. Conclusion: Our case is a step towards the direction pointing to the rare possibility of bacterial meningitis complicating snake bites which needs further research

    New Constraints on Dispersive Form Factor Parameterizations from the Timelike Region

    Get PDF
    We generalize a recent model-independent form factor parameterization derived from rigorous dispersion relations to include constraints from data in the timelike region. These constraints dictate the convergence properties of the parameterization and appear as sum rules on the parameters. We further develop a new parameterization that takes into account finiteness and asymptotic conditions on the form factor, and use it to fit to the elastic \pi electromagnetic form factor. We find that the existing world sample of timelike data gives only loose bounds on the form factor in the spacelike region, but explain how the acquisition of additional timelike data or fits to other form factors are expected to give much better results. The same parameterization is seen to fit spacelike data extremely well.Comment: 24 pages, latex (revtex), 3 eps figure

    Nuclear spins, magnetic moments and quadrupole moments of Cu isotopes from N = 28 to N = 46: probes for core polarization effects

    Full text link
    Measurements of the ground-state nuclear spins, magnetic and quadrupole moments of the copper isotopes from 61Cu up to 75Cu are reported. The experiments were performed at the ISOLDE facility, using the technique of collinear laser spectroscopy. The trend in the magnetic moments between the N=28 and N=50 shell closures is reasonably reproduced by large-scale shell-model calculations starting from a 56Ni core. The quadrupole moments reveal a strong polarization of the underlying Ni core when the neutron shell is opened, which is however strongly reduced at N=40 due to the parity change between the pfpf and gg orbits. No enhanced core polarization is seen beyond N=40. Deviations between measured and calculated moments are attributed to the softness of the 56Ni core and weakening of the Z=28 and N=28 shell gaps.Comment: 13 pagers, 19 figures, accepted by Physical Review

    Electrochemical integration of graphene with light absorbing copper-based thin films

    Full text link
    We present an electrochemical route for the integration of graphene with light sensitive copper-based alloys used in optoelectronic applications. Graphene grown using chemical vapor deposition (CVD) transferred to glass is found to be a robust substrate on which photoconductive Cu_{x}S films of 1-2 um thickness can be deposited. The effect of growth parameters on the morphology and photoconductivity of Cu_{x}S films is presented. Current-voltage characterization and photoconductivity decay experiments are performed with graphene as one contact and silver epoxy as the other

    Sustainable Agricultural Development through Value Addition and Linking of Farmers to Markets in Telangana State of India

    Sustainable agricultural development can be ensured by empowering smallholder farmers with inclusive business models that enhance their livelihoods. This paper outlines the interventions by International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in collaboration with Integrated Tribal Development Agency (ITDA), Telangana, to enhance livelihoods of tribal smallholders in Adilabad district of Telangana State, India, by providing value addition opportunities and market linkages. Tiryani, Wankidi and Karameri mandals of Adilabad district of Telangana were selected for the interventions, being some of the most backward regions inhabited by tribals. Data analysis was done using MS Excel software. The interventions focused on providing access to seed, establishing pilot processing units for value addition to pigeon pea, training and capacity building on crop production and handling of processing units and providing market linkages. Efficiency of the processing units and the effect of pre- treatments on milling efficiency was also studied and processing parameters optimized. The interventions helped increase income of farmers by 86 per cent, established two pigeon pea processing units and streamlined the pigeon pea value chain in the region
