    Ba1-xBi2x/3TiO3 ceramics were prepared by solid state reaction route in different value of x (i.e., x = 0, 0.01, 0.025, 0.05, 0.075, 0.1). Structural property of all compositions is studied by XRD and surface morphology of the sintered pellets is studied by SEM analysis. XRD patterns reports the single phase tetragonal crystal system of the space group P4mm and pattern matched with the standard pattern JCPDS no. 05-0262 and it reveals the crystalline sizes decreases with increase the Bi concentration. SEM image shows the grain size decreases for x=0.01 and x=0.025 and increases with further addition of Bi concentration. The chemical composition of sintered pellets is analyzed by EDX. The temperature dependency dielectric study of Ba1-xBi2x/3TiO3 (i.e., x = 0, 0.025, 0.05) composition is studied. Dielectric constant and transition temperature decreases for x=0.025 and again increases for x=0.05. Curie constant values are calculated from the Curie Weiss law

    Background: UGI bleeding is defined as bleeding that occurs in the digestive tract proximal to the ligament of treitz. Intermittent dosage regimen IV bolus and high dose IV continuous infusion forms helps in achieving and maintaining this pH goal of more than 6 which forms optimal environment for peptic ulcer healing and clot stabilization to occur. Theoretically, high-dose IV continuous infusion should provide the most potent acid suppression. Aims and objective was to compare the efficacy of intermittent dose of pantoprazole given for 3 days i.e. 40mg intravenous twice a day versus continuous infusion dose of pantaprazole i.e. 80mg intravenous bolus followed by 8mg/hour for first 72hours in the treatment of UGI bleed.Methods: Patients of UGI bleed were randomly assigned to receive either continuous or intermittent regimen of pantaprazole as a part of management.Results: Among 118 patients of peptic ulcer disease, 7 patients had rebleed and 111 patients had no rebleed.3 patients among 59 patients who received continuous regimen and 4 patients among 59 patients who received intermittent regimen had rebleed with a total of 7 patients among 118 patients. Among 118 patients only 2 patients of the total had need for surgery for stabilization. Among 59 patients who received continuous regimen 2 patients needed surgery while none of the 59 patients who received intermittent regimen needed for surgery. Of the 118 patients 10 patients had mortality at the end of 30 day period. In both the regimes 5 patients died.Conclusions: The difference between Rockall score of the intermittent and continuous regimen group was statistically insignificant. The incidence of rebleed was 5.1 % for continuous and 6.7% for intermittent regimen which was statiscally insignificant. The incidence of mortality was similar 8.5%in both regimen

    The evaluation of climatic change impact on maize grain and biomass yield under different N management practices through a well-calibrated and validated APSIM model in Vertisol of central India has been made. Climate scenarios were derived from seven global climate models (GCM) for two representative concentration pathways (RCPs), i.e. RCP4.5 and RCP8.5, and two-time slices, i.e. 2050 and 2080. The five N scenarios, namely N0%, N50%, N100%, N150%, and 100% organic, were studied in different climatic scenarios. The probability of exceedance showed that N0%, N50%, N100%, N150%, and 100% organic treatments have a 50% chance of yield greater than 1.0, 3.40, 4.20, 4.45 and 3.84 t ha-1, respectively. The average reduction of maize yield was -44.4, -20, -19.7 - 17.9 and 22.5 per cent in N 0%, N 50%, N 100%, N 150%, 100% organic, respectively under RCP4.5 over the baseline period (1980-2010). For RCP8.5, the average reduction of maize yield in N 0%, N 50%, N 100%, N 150%, 100% organic was 41.2, 21.2, 20.8 20.6 and 23.1 per cent, respectively. Simulation results suggested that a higher decrease of maize yield in 100 per cent organic treatments than inorganic treatments is due to variability in N uptake

    International audienceCosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probes give access to fundamental physics not available by any other means, helping elucidate the underlying theory that completes the Standard Model. The last decade has witnessed a revolution of exciting discoveries such as the detection of high-energy neutrinos and gravitational waves. The scope for major developments in the next decades is dramatic, as we detail in this report
