A hydrophysics mathematical model of a shallow water body is proposed, including the pollutants (PS) transport equation, taking into account their gravitational settling, numerically implemented in software module form. The developed makes it possible to evaluate pollutant concentrations distribution during deposition from aquatic environment surface. for predicting along vertical coordinate re...

Cirrus clouds are composed of ice crystals condensed from humidity due to low temperature condition in the upper atmosphere. The microphysics of cirrus clouds including sizes and shapes of ice particles are not well understood but are important in climate modeling. Ice crystal will fall under gravitational sedimentation to reach terminal velocities which depend on the size, mass, and ice habit....

This paper presents the combined technologies, rheology, zeta potential and particle size measurements, that are important to characterize particle suspensions. We will use a system that sediments at room temperature and explain why different techniques are needed to characterize the system to show its potential stability INTRODUCTION Suspensions or dispersions of particles or droplets in a liq...

We use a combination of original light scattering techniques and particles with unique optical properties to investigate the behavior of suspensions of attractive colloids under gravitational stress, following over time the concentration profile, the velocity profile, and the microscopic dynamics. During the compression regime, the sedimentation velocity grows nearly linearly with height, imply...

Abstract We enhance the treatment of crystallization for models white dwarfs (WDs) in stellar evolution software Modules Experiments Stellar Astrophysics (MESA) by implementing carbon–oxygen (C/O) phase separation. The separation process during leads to transport oxygen toward centers WDs, resulting a more compact structure that liberates gravitational energy as additional heating modestly slow...

The starch statolith hypothesis of gravity sensing in plants postulates that the sedimentation of statoliths in specialized statocytes (columella cells) provides the means for converting the gravitational potential energy into a biochemical signal. We have analyzed the sedimentation kinetics of statoliths in the central S2 columella cells of Arabidopsis thaliana. The statoliths can form compact...

The swimming behaviours of two species of ciliates characterized by different mechanosensory and ciliary motor properties were investigated under hypergravity up to 5.4 g. The experiments were designed to examine large numbers of cells using video recording, digital data processing and statistics for the documentation of the rates and orientations of swimming. The gravikinetic responses (change...

Conformal connection of scalar field is shown to produce possible non-metricity in affine connection spaces. In case of self-consistent solution the non-metricity is a correction to background Riemannian structure with respect to gravitational constant and its magnitude may be essential in the early Universe.
