ON THE DAMPING OF THE FLUCTUATIONS OF ATOMIC GROUPS IN WATER ENVIRONMENT

In this work, we continue our research of the problem concerning the proteins' functioning efficiency. The system under study, a three-dimensional harmonic oscillator, placed in a water "drop" which consists of 264 molecules, simulates the fluctuations of atomic groups in a non-stationary charge pattern field of an active center. The latter results in a break of chemical bonds. Damping time and Q-factor calculations of atomic fluctuations at various frequencies, intensities of interaction with the water environment, and also at various atomic weights are carried out. By means of the argon-like model of water molecules the Q-factor of atomic fluctuations is also estimated. The results obtained are compared with those calculated with the SP3-model.

Electric and Magnetic Potentials of Uniformly Accelerated Charge Distributions

Jefimenko gave recently [1] new expressions for the electric and magnetic potentials of uniformly moving, time-independent charge distributions. We discuss these potentials for uniformly accelerated distributions. As Jefimenko did. we implement two procedures either converting directly retarded into present position integrals or using relativistic transformations for a stationary charge in an instantaneous comoving inertial frame (Frenet-Serret tetrad). We discuss why, at the difference of what happens for uniform motions [1], both procedures provide different expressions for potentials.
