  • (19) Three methods of obtaining distance constraints from 2D NOE peak intensities are examined: one entails a conservative use of ISPA, one assumes the ISPA to be fairly accurate, and one utilizes an iterative relaxation matrix method called MARDIGRAS (matrix analysis of relaxation for discerning the geometry of an aqueous structure), developed in this laboratory.
  • (20) They opposed the first iteration of the House healthcare bill as not going far enough to repeal Obamacare.

Recursion


Definition:

  • (n.) The act of recurring; return.

Example Sentences:
