PRELIMINARY STUDIES " suggested that the capacity of a drug to suppress ventricular arrhythmia might be inherent in a chemical structure which does not possess certain actions previously associated with antiarrhythmic activity, e.g., elevation of electric threshold, depression of conduction, and local anesthesia. Ambonestyl, 2-diethylaminoethyl-isonicotinamide,* (MC 4112), was found to be a com...

‎We consider nonconvex vector optimization problems with variable ordering structures in Banach spaces‎. ‎Under certain boundedness and continuity properties we present necessary conditions for approximate solutions of these problems‎. ‎Using a generic approach to subdifferentials we derive necessary conditions for approximate minimizers and approximately minimal solutions of vector optimizatio...

The N-(2-benzoyl-phenyl) oxalyl derivatives are important models for studying of three-centered intramolecular hydrogen bonding in organic molecules. The quantum theoretical calculations for two crystal structures of N-(2-benzoyl-phenyl) oxalyl (compounds I and II) were performed by Density Functional Theory (B3LYP method and 6-311+G* basis set). From the optimized structures, geometric paramet...
