During the processes of primary succession and soil development, large stocks of organic C with very long residence times accumulate in many soils. Soluble organic C adsorbed by soils may contribute to the stock of organic C accumulating during soil development. We determined whether the mineralization rate of water-soluble organic C and the insoluble residue from C-labelled leaf litter added t...
BACKGROUND To test the value of a simulated Family Conference Objective Structured Clinical Exam (OSCE) for resident assessment purposes, we examined the generalizability and construct validity of its scores in a multi-institutional study. METHODS Thirty-four first-year (PG1) and 27 third-year (PG3) surgery residents (n = 61) from 6 training programs were tested. The OSCE consisted of 2 cases...
Improving our understanding of cloud chemistry depends on achieving better chemical characterization (90% of the organic carbon [OC] fraction remains uncharacterized) and, consequently, assessing the reactivity of this complex system. In this manuscript, we report for the first time the concentrations of 16 amino acids (AAs) in 25 cloud water samples. The concentrations of individual AAs ranged...
