The effects of apple pomace diets on rumen microbial population, movement of ingesta from the rumen, and water intake were studied in two trials with beef steers. Trial 1 was a 5 • 5 Latin square in which five ruminal fistulated steers were fed either corn silage plus cottonseed meal (CSM), apple pomace plus CSM, apple pomace plus urea, apple pomace plus urea and starch, or apple pomace plus ur...

A novel graphene-coated Ni electrode was developed in this investigation to improve corrosion resistance while unexpectedly enhancing the ammonia generation rate in the electrochemically induced urea to ammonia (eU2A) process, which is an electrochemical onsite ammonia generation method. The development of the electrode is crucial for the eU2A reactions since in the ammonia generation process, ...

to study the effect of urea application in safflower (carthamus tinctorius) and determination of effective traits on its yield, a factorial experiment based on randomized complete block design in three replications was conducted in tabriz, iran, during 2012. studied factors were urea rate levels as 100, 150 and 200 kg/ha and urea application times 100% in sowing time, 50% sowing time + 50% stem...

The objectives of this study were to evaluate the potential for using blood urea N concentration to predict urinary N excretion rate, and to develop a mathematical model to estimate important variables of N utilization for several different species of farm animals and for rats. Treatment means (n = 251) from 41 research publications were used to develop mathematical relationships. There was a s...

Compartmentalized reaction networks regulating signal processing, communication and pattern formation are central to living systems. Towards achieving life-like materials, we compartmentalized urea-urease more complex urea-urease/ester-esterase pH-feedback into hydrogel spheres investigate how fuel-driven pH fronts can be sent out from these regulated by internal networks. Membrane characterist...

in order to investigate the effect of rhizobium bacteria, mycorrhiza fungi and foliar application of urea on qualitative and quantitative traits of soybean an experiment was conducted based on randomized complete block design with four replications. the experiment included six treatments as: control (c), rhizobium bacteria (r), rhizobium bacteria + mycorrhiza fungi (r+m), rhizobium bacteria + f...

The reduction of horse heart cytochrome c with ascorbate in the absence of urea and in its presence, 0 to 8 M, pH 7.0, has been investigated using a stopped flow technique and the absorptivity at 550 nm as the monitoring probes, and by using the rate of oxidizability with molecular oxygen. Reduction is found to be consistent with a mechanism involving (i) a urea-dependent equilibrium step betwe...
