Experimental investigations of the thermal diffusion motion of individual probe microparticles in various liquids have
been carried out by using the phase-sensitive laser method of light-scattering spectroscopy. It has been shown that at
observation times τ ≥ 1s there is a good agreement between the obtained experimental data and the well-known Einstein-Smoluchowski linear law of Brownian motion (see manuscript for equation). At small observation times τ<<1 s, the square law of motion (see manuscript for equation) is valid. The molecular cooperative mechanism of action of the liquid on a microparticle
as a result of relaxation of thermal spatial inhomogeneities is discussed.
The results of investigations of superlong-period and tidal oscillations of the Earth obtained by using the data of a laser
deformographic system are presented in this paper. The phenomenon of tight correlation between superlong-period oscillations
in the lithosphere and in the atmosphere unknown before has been discovered. Besides, we discovered abnormal
phase shifts between experimentally measured lunisolar tides in two orthogonal directions.
In this paper, experimental results of investigations of the physical mechanism of transcapillary exchange by the method of phase sensitive laser spectroscopy of light scattering are presented. Acoustic oscillations of the walls of microvessels (arterioles, capillaries, and venules) which provide transcapillary exchange have been detected for the first time.
The problem of the study of an ordered movement of the biological systems by high-resolution light scattering spectroscopy is discussed. The class of the objects for investigation of their dynamic properties in the water solutions is determined. The early experimental results of the observed peculiarities of the macromolecular motility by the example of DNA are presented.
The results of the study of dynamic peculiarities of deformational oscillations of Earth crust with periods in the range from 10 to 300 sec by He-Ne laser dephormograph placed in underground gallery are presented. The mean square amplitude of deformational noise observed during one month is about 0.01 micrometers. It has constant components and variable one with period 24 hours. A mechanism of the deformational noise generation and a practical implementation of the laser apparatus and observed phenomenon for geodynamic and seismic monitoring are discussed.
The results of the study of the laser radiation scattered on living micro-organisms in water suspension in time and spectral domain are presented. The comparison of the dynamic characteristics of the motility of bacteria Escherichia and Pseudomonas is made.
