Background: Elevated D-Dimer levels are predictive of long-term outcomes in patients with high risk for cardiovascular events, however, little is known about their value in patients with indication for right heart catheterization (RHC). We hypothesized that D-Dimer levels are predictive of long-...
As such, the CEC determination of swelling clays using the MB adsorption method is justified. However, SSA determination by the MB method is correct only if the charge density is less than the projected area of 120-130 angstrom(2) for an MB dimer. This suggests that the previous assumption...
alcohols, organic acids, ketones) at high temperature with or without a catalyst [39]. Extraction is based on the solubility of lignin in the organic solvent used [40]. The main advantage of this organosolv method is the easy recovery of the solvent and lignin ...
Stereomutation was high (∼40%). The addition of N-hydroxybenzotriazole doubled the degree of epimerization. A rationale is offered in order to explain the enantiomeric induction. High dilution was necessary to avoid side products (dimer/trimer) formation. However, dilution does not effect the ...
