Early Galactic Evolution of Carbon, Nitrogen and Oxygen [PDF]
, 2000 We present results on carbon, nitrogen, and oxygen abundances for a sample of unevolved metal-poor stars with metallicities in the range -0.3< [Fe/H]< -3. Oxygen abundances derived from different indicators are compared showing consistently that in the range 0.3 >[Fe/H]>-3.0, the [O/Fe] ratio increases from approximately 0 to 1.

Ultra-Rapid Nitrogen Balances in Man
Experimental Biology and Medicine, 1971 SummaryFasting healthy participants were in negative nitrogen balance when given glucose calories alone intravenously. Reversal of nitrogen balance from negative to positive occurred during the intravenous administration of an amino acid-glucose mixture.

Anomalous Weight Behavior in YBa2Cu3O7 Compounds at Low Temperature [PDF]
arXiv, 1997 YBa2Cu3O7 high temperature superconductor samples were weighed on an electronic balance during a warming cycle beginning at 77 degrees K. The experiment was configured so that the YBa2Cu3O7 material was weighed along with a magnet, a target mass, and liquid Nitrogen coolant. The weights were captured during Nitrogen evaporation.

Revisiting Effects of Nitrogen Incorporation and Graphitization on Conductivity of Ultra-nano-crystalline Diamond Films [PDF]
arXiv, 2019 Detailed structural and electrical properties of ultra-nano-crystalline diamond (UNCD) films grown in H$_\text{2}$/CH$_\text{4}$/N$_\text{2}$ plasma were systematically studied as a function of deposition temperature ($T_d$) and nitrogen content ($\%$ N$_2$) to thoroughly evaluate their effects on conductivity. $T_d$ was scanned from 1000 to 1300 K for

Aflatoxin and Nitrogen Balance in the Young Calf
Journal of Dairy Science, 1973 Abstract The purpose of this experiment was to determine effects of aflatoxin on the nitrogen balance of 2- to 8-wk old male calves. Daily doses of a crude aflatoxin preparation were administered orally to four groups of three calves at 0, .02, .04, and .08 mg/kg body weight. Doses were adjusted weekly for changes in body weight.

NITROGEN UTILIZATION BY DAIRY GOATS OFFERED DIFFERENT NITROGEN SOURCES AS SUPPLEMENTS IN HIGH ISOCALORIC ENERGY CONCENTRATES [PDF]
Journal of the Indonesian Tropical Animal Agriculture, 2011 Twelve growing female goats (Anglo-Nubian) were assigned to a multiple latin square design experiment to evaluate the effectiveness of additions of nitrogen (N) supplements to a high isocaloric energy ration on N utilization.

Genetic covariance components for measures of nitrogen utilization in grazing dairy cows
Journal of Dairy Science: Improved nitrogen utilization of dairy production systems should improve not only the economic output of the systems but also the environmental metrics. One strategy to improve efficiency is through breeding programs. Improving a trait through breeding
