Tunable Auxiliary Mass Damper with Friction Joint: Numerical Assessment effectiveness of the proposed TAMD is numerically evaluated based on mass and frequency ratios variations for each strategy. Therefore, a multi-degree-of-freedom (MDOF) system analysis is made in order to verify the TAMD’s robustness and efficiency.盖他为秘密 发表于 2025-3-27 10:02:15

Oxidations Catalyzed by Ruthenium Porphyrins,action is effected by a monooxygenase enzyme such as cytochrome P-450 which contains iron protoporphyrin IX as the prosthetic group with an axial thiolate ligand provided by a cysteinyl amino acid residue of the protein. Investigations on the structure and oxidizing ability of cytochrome P-450 as we
