The utilization of wastewater for useful fuel has been gathering recent attention due to society’s need for alternative energy sources. The electrooxidation of urea found at high concentrations in wastewater simultaneously accomplishes fuel production and remediation of harmful nitrogen compounds that currently make their way into the atmosphere and groundwater. Pure hydrogen was collected in t...

This research was conducted to investigate the effects of feeding of barley grain (whole or cracked) combined with two different protein sources (urea or soybean meal) on nutrients digestibility and rumen parameters (pH and ammonia concentration). Four rumen fistultated Mehraban sheep was used that the mean body weight of sheep was 36.5±0.5 kg. The the experiment was conducted in change over de...

Foliar application of nitrogen (N) is used to supplement soil N application in order to meet high N requirements of crops (Oosterhuis, 1999). Urea is the most common foliar N source in cotton, due to its relatively low toxicity, quick absorption, and low cost (Maples and Baker, 1993; McConnell et al., 1998, Oosterhuis and Bondada, 2001). However in the literature, reports of yield increments wi...

Hydrogen bonding with fluoride is a key interaction encountered when analyzing the mode of action of 5'-fluoro-5'-deoxyadenosine synthase, the only known enzyme capable of catalyzing the formation of a C-F bond from F-. Further understanding of the effect of hydrogen bonding on the structure and reactivity of complexed fluoride is therefore important for catalysis and numerous other application...

A field experiment was designed to study the effects of nitrogen (N) source and urease inhibitor N-(nbutyl) thiophosphoric triamide (NBPT) or nitrification inhibitor dicyandiamide (DCD) on nitrous oxide (N2O) emission and N use efficiency (NUE) in a sandy loam soil. Six treatments including no N fertilizer (control), N fertilizer urea alone (U), urea plus NBPT (NBPT), urea plus DCD (DCD), urea ...

An experiment was conducted to study wheat grain protein increasing through foliar application of Nitrogen afterflowering. The RCBD design was analysed with three replications and four N-treatments as foliar application as(N0=0, N1=4kg.ha-1 Urea, N2=8kg.ha-1 Urea, N3=4kg.ha-1 Ammonium Sulfate). Results showed that seed proteincontent increased significantly by foliar application of Nitrogen. Da...
