Bryan Hubbell9 & Richard T. Burnett1 Most studies on the association between exposure to fine particulate matter (PM2.5) and mortality have considered only total concentration of PM2.5 or individual components of PM2.5, and not the combined effects of concentration and particulate composition...
Composition of matter and method of its preparationMARTELL CHARLES
The universe is vast, and the longer we observe it, the more we learn about its composition and structure. But historians of science tell us that periods of steady growth in science tend to last only so long: they are interrupted by revolutions during which the old assumptions are thrown ou...

The amount and composition of root exudates—low-molecular-weight carbon compounds released from living plant roots into soil—are expected to shift under global change, and a growing body of work indicates that root exudates have important impacts on stable soil organic matter dynamics. However, mo...
(APOEε) status; however, the composition of genetic markers within the present study limited our ability to examine genetic effects. To better characterize SCD, future studies should more fully evaluate the nature of cognitive concerns, take a longitudinal approach, and also incorporate other ...
