Coals having 69% or more fixed carbon on the dry, mineral -m a tter-free basis are classified according to fixed carbon, regardless of gross calorific value. 

At times, mining and some oil and gas operations are entitled to an alternate depletion allowance calculated from a percentage of gross sales. A current tax manual should be consulted to get the percentage depletion allowance for the mineral being studied.

Many bacteria possess a high-affinity urea uptake system accompanied by an intracellular urease enzyme (135). Nielsen et al. (136) have measured both natural urea turnover rates and gross N mineralization rates in situ using a new...

A number of substances may interfere with stool examination. Particulate materials such as barium, antacids, kaolin, and bismuth compounds interfere with morphologic examination, and oily materials such as mineral oil create small, refractile droplets that make examination difficult. Antimicrobial agents, particularly broad-spectrum antimicrobial agents, may suppress amebae. If any of these substances have been used, specimens should not be submitted until the substances have been cleared (generally 5 to 10 days). A fecal specimen may appear satisfactory by gross examination when there is still barium, etc., which can interfere with microscopic examination.
