At lower temperatures the clearly defined components (match quality > 80%) included mainly
alkanes, oxygen-containing compounds and some heteroatomic compounds.
Where F32 is the mean fecal concentration of even chain n-alkane after CRC dosed, [B.sub.32] is the background concentration of even-chain n-alkane before CRC administrated; FO is the mean fecal DM output measured during 3 days after CRC administration; [AFR.sub.32] is the recovery rate of [C.sub.32]
alkane in feces measured in previous study (Sun et al., 2008).
RESULTS: We found that 24-hr transition metals and
alkanes were associated with increased odds [0.26%; 95% confidence interval (CI), 0.02-0.48; and 0.37%; 95% CI, 0.04-0.72, respectively] of hospital admissions for cardiovascular disease (CVD).
The use of plant wax
alkanes as marker substances in studies of the nutrition of herbivores: a review.
Mat Zuckerman, Chief Executive Officer of
Alkane. "Operators have long asked: why three grades of fuel for cars, while truckers can only buy one grade of diesel?
Interpretation of odd-even
alkane predominance can be potentially complicated by the presence of certain bacteria which have been shown to exhibit high molecular weight n-alkane distributions showing no odd carbon preference (Han and Calvin, 1969).
