Nitrogen doped tetrahedral amorphous carbon (ta-C:N) thin films were grown on p-Si(1 1 1) substrates using filtered cathodic vacuum arc (FCVA) deposition by varying nitrogen flow rate. The effect of nitrogen flow rate on the corrosion performance of the films was investigated through potentiodynamic polarization and immersion tests in 0.6 M NaCl solutions. The polarization results showed that t...
in order to evaluation of nitrogen fertilizer application and seed inoculation by azotobacter and azosprillium on yield, rate and grain filling period of corn sc-500 cultivar, a factorial experiment was conducted based on randomized complete block design with three replications in farm of agriculture and natural resource research center of azarbaijan-e- shargi province in 2011. the factors were...
To study the effect of sowing time and nitrogen levels on growth, yield and nitrogen efficiency of quinoa cv. Titicaca, a field experiment was conducted at in 2017-2018 growing season research farm of Agricultural and Natural Resources Sciences University of Khuzestan, Ahvaz, Iran. The experiment was conducted in split plot arrangement in randomized complete block design with four replications....
Hepatic urea synthesis is the organism's main channel for the disposal of nitrogen and it may be an 'essential' liver function. In six control subjects and five patients with cirrhosis of the liver urea synthesis was studied during continuous infusion for six to 24 hours of about 3 mmol alpha-amino nitrogen/h X kg body weight. The urea synthesis rate was calculated in intervals of two hours as ...
We investigated the variation in leaf nitrogen to phosphorus ratios of tropical tree and liana seedlings as a function of the relative growth rate, whole-plant water-use efficiency, soil water content and fertilizer addition. First, seedlings of 13 tree and liana species were grown individually in 38-l pots prepared with a homogeneous soil mixture. Second, seedlings of three tree species were g...
