Observations of neutral-current nu interactions on deuterium in the Sudbury Neutrino Observatory are reported. Using the neutral current (NC), elastic scattering, and charged current reactions and assuming the standard 8B shape, the nu(e) component of the 8B solar flux is phis(e) = 1.76(+0.05)(-0.05)(stat)(+0.09)(-0.09)(syst) x 10(6) cm(-2) s(-1) for a(More)
The Sudbury Neutrino Observatory (SNO) has measured day and night solar neutrino energy spectra and rates. For charged current events, assuming an undistorted 8B spectrum, the night minus day rate is 14.0%+/-6.3%(+1.5%)(-1.4%) of the average rate. If the total flux of active neutrinos is additionally constrained to have no asymmetry, the nu(e) asymmetry is(More)
RFID technology finds immense applicability in domains utilizing identification as the base operation such as in access control, localization, etc. It may be designed to work well for either singular or a limited range of applications. However, the strict-coupling between applications and RFID equipment must be relaxed to scale up their usability. In order(More)
Solar neutrinos from (8)B decay have been detected at the Sudbury Neutrino Observatory via the charged current (CC) reaction on deuterium and the elastic scattering (ES) of electrons. The flux of nu(e)'s is measured by the CC reaction rate to be straight phi(CC)(nu(e)) = 1.75 +/- 0.07(stat)(+0.12)(-0.11)(syst) +/- 0.05(theor) x 10(6) cm(-2) s(-1).(More)
RFID technology finds immense applicability in various domains but taming the base operation of RFID equipment to work seamlessly with enterprise applications still remains a cumbersome job. For the purpose of taming RFID equipment, RFID middlewares are deployed which generally provides Automatic Registry, Configuration, Monitoring, and Control. Though RFID(More)
One hundred water samples collected from different water supply sources in Hazara Division were analysed for their mineral constituents. The concentrations of almost all the mineral constituents did not exceed the desirable limits. Fluorides and iodides were either absent in some samples or were in very low concentrations indicating a possible correlation(More)

The effect of propranolol on the electric stimulation of rat isolated diaphragm shOwed the depression of its isometric force of contraction. This depressant effect of propranolol on the rat isolated diaphragm was produced in doses much higher than the doses required for the beta adrenergic receptor blocking activity. Isoprenaline showed no effect on the rat(More)
