The present study examined the antioxidant defense of glutamine on plasma and liver antioxidant status in broilers under PHS with respect to changes in the levels of lipid peroxidation marker malondialdehyde (MDA), total antioxidant status (TAS) and the activities of anti peroxidative enzymes [superoxide dismutase (SOD) and glutathione dependent antioxidant enzymes glutathione peroxidase (GPX)]...

In Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing system using beamforming improve the receive Signal to Noise Ratio. In the transmission signals after beam forming the Peak-to-Average Power Ratio (PAPR) is a major issue in Orthogonal Frequency Division Multiplexing systems, High Peak to Average Power Ratio is complicated to design the power amplifier and also increas...

in this paper, we investigate the parameters affecting total harmonic distortion (thd) and power supply rejection ratio (psrr) in pwm class d amplifiers (cdas) on the basis of linear models with feedback. from our mathematical analysis, we show that the thd of a pwm class d amplifier with feedback can be improved by increasing the gain of the integrator through adding another amplifier at the o...

this paper proposes a low voltage (±0.55v supply voltage) low power (44.65µw) high common mode rejection ratio (cmrr) differential amplifier (d.a.) with rail to rail input common mode range (icmr), constant transconductance (gm) and enhanced frequency performance. its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

the relative eye size, types of visual cell and mosaic, and the existence of retinal tapetum in the eyes of the spotted barb puntius binotatus were determined to gain baseline information on its visual capability. the p. binotatus acquired relatively larger eye size than the other similar sized freshwater fish species with its retina being contained both cone and rod visual cells (cone ellipsoi...

an in vivo experiment was conducted to determine the effect of dietary betaine supplementation (betafin®) as a replacement for methionine on broiler performance and carcass characteristics. in a completely randomized design (crd) with five treatments of betaine levels (at 0, 25, 50, 75, and 100% in replacement for methionine) and five replicates of 10 birds/replicate, two hundred fifty-day-...

three-hundred and twenty 7-day-old ross 308-strain broiler chickens were fed diets containing 0 or 125 ppb aflatoxin b 1 (afb1) from 7 to 28 days of age. sodium bentonite (0.5%), yeast (saccharomyces cervisiae) 0.2%, hydrated sodium calcium aluminosilicate (hscas) (0.5%), ammonia (0.5%), formycine (0.1%), and toxiban (0.1%) were added to the basal diet, as fed basis to determine the effects of ...
