Protective effects of hexane fraction of Costus afer leaves against sodium arsenite-induced hepatotoxicity and nephrotoxicity in male albino wistar rats [PDF]
The Ukrainian Biochemical Journal, 2020 Arsenite is a toxic metallic pollutant known to cause hepatotoxic and nephrotoxic injuries. Costus afer Ker Gawl. is an indigenous medicinal plant used as therapy for numerous tissue disorders. Thus, this study investigated the protective potential of C.

Optimal Alignment Sensing of a Readout Mode Cleaner Cavity [PDF]
, 2011 Critically coupled resonant optical cavities are often used as mode cleaners in optical systems to improve the signal to noise ratio (SNR) of a signal that is encoded as an amplitude modulation of a laser beam. Achieving the best SNR requires maintaining

Radio Polarimetry of Tycho's SNR [PDF]
Symposium - International Astronomical Union, 1990 The remnant of Tycho's supernova of 1572 has been polarimetrically imaged using the 4 configurations of the VLA at wavelengths of 22 and 6 cm. A few data were also obtained at wavelengths of 21, 19, and 18 cm in the B configuration to check for any ambiguities in the Faraday rotation measurements and to look for deviations from the λ2 dependence of the

Magnetic Fields in Young SNRS [PDF]
Symposium - International Astronomical Union, 1990 There are two very important properties of the magnetic fields in supernova remnants which we wish to emphasize: 1) The net radial orientation of the magnetic vectors throughout the shell and 2) an apparent gradual increase in the fractional polarization with evolutionary age.

The Rate of Type Ia Supernovae at High Redshift
, 2005 We derive the rates of Type Ia supernovae (SNIa) over a wide range of redshifts using a complete sample from the IfA Deep Survey. This sample of more than 100 SNIa is the largest set ever collected from a single survey, and therefore uniquely powerful ...

Optimal Power Allocation for Channel Estimation in MIMO-OFDM System with Per-Subcarrier Transmit Antenna Selection [PDF]
, 2015 A novel hybrid channel estimator is proposed for multiple-input multiple-output orthogonal frequency- division multiplexing (MIMO-OFDM) system with per-subcarrier transmit antenna selection having optimal power allocation among subcarriers.
