Energy and nitrogen balances were performed in 12 very low birthweight infants fed on either human milk or on a preterm formula. Energy and nitrogen retention were significantly higher in those given the formula feed (p less than 0.05). Highly significant correlations were found between nitrogen intake and nitrogen retention and between energy retention and nitrogen retention (p less than 0.001...

Teotia, M., Teotia, S. P. S., and Kunwar, K. B. (1971). Archives of Disease in Childhood, 46, 686. Endemic skeletal fluorosis. Endemic skeletal fluorosis is described in 6 children aged 11 or over. Four cases were crippled with severe deformities in the spine, hips, and knees. All showed positive phosphorus, magnesium, and nitrogen balances and excessively positive calcium balances. The skeleta...

Nitrogen (N) balance has been identified as a principal agri-environmental indicator. In addition to national N balances, calculation of N balances for different agricultural regions is also recommended. In this study, national and regional net N balances for Finland were calculated. The net N balance is the result of deducting the NH3-N losses from manure and fertilisers from the gross N balan...

Sustainable production requires balanced resource use and it is the management decisions at a household level that determine nutrient fluxes and the economic viability of enterprises. Traditionally, the agricultural systems of the mid-hills of Nepal have relied on the close integration of forestry, livestock husbandry and crop production but increasing population and other social changes are st...
