    Abstract We show how gravitational-wave observations with advanced detectors of tens to several tens of neutron-star binaries can measure the neutron-star radius with an accuracy of several to a few percent, for mass and spatial distributions that are realistic, and with none of the sources located within 100 Mpc. We achieve such an accuracy by combining measurements of the total mass from the inspiral phase with those of the compactness from the postmerger oscillation frequencies. For estimating the measurement errors of these frequencies, we utilize analytical fits to postmerger numerical relativity waveforms in the time domain, obtained here for the first time, for four nuclear-physics equations of state and a couple of values for the mass. We further exploit quasiuniversal relations to derive errors in compactness from those frequencies. Measuring the average radius to well within 10% is possible for a sample of 100 binaries distributed uniformly in volume between 100 and 300 Mpc, so long as the equation of state is not too soft or the binaries are not too heavy. We also give error estimates for the Einstein Telescope.

    Abstract The various factors affecting static generation in carpets such as relative humidity, fiber type, shoe-sole material, carpet backing, and treadwear have been examined in this paper. Experiments to determine threshold level of static sensitivity in humans have been made. Critical evaluations of current carpet static test methods have been made, and the use of low voltage (discharge voltage) instead of maximum voltage value is suggested. A new carpet static test method using a motorized treadmill device has been described.

    Abstract Studies on the induction of histidase were made with normal and nitrofurantoin resistant strains of Vibrio el tor. Nitrofurantoin resistant strains showed decreased level of induction in comparison to normal Vibrio el tor. The effect of different inhibitors like actinomycin D, chloramphenicol, tetracycline, nitrofurantoin and rifampicin on histidase induction was also studied. The mechanism of inhibition caused by the antibiotics is discussed.

    Abstract Administration of HgCl2 at a dose of 5 mg/kg body weight/day for 15 days to male albino rats brought about a marked depression of the scavenging enzymes viz. glutathione peroxidase and glutathione S-transferase, in kidney. There was an adaptive rise in the levels of catalase and no increased lipid peroxidation was observed. The levels of both glutathione and glutathione reductase were decreased, whereas total thiol increased. In the intoxicated rats, Vitamin-E was effective in bringing back glutathione levels to normal. The adaptation in this group of animals is reflected by increased superoxide dismutase activities. Feeding of Vitamin-E alone could cause a depression of the scavenging enzymes like glutathione peroxidase and glutathione S-transferase along with a slight lowering of glutathione levels.
