For evaluating the motion of a solid body in a gaseous medium, one has to know the drag constant of the body. It is therefore not surprising that this subject was extensively investigated in the past. While accurate knowledge is available for the dra

This important monograph is the first comprehensive compendium of engineering models used in high-speed penetration mechanics.The book consists of two parts. The first part (more than a quarter of the book's content) is in fact a handbook giving a ve

We suggest a two-dimensional model of adsorption of trace atmospheric gases by mineral dust particles with origin from desert soils. The model is based on the application of theory of turbu...

Mineral dust emission is a major process in determining the global dust cycle. At a global scale there is still uncertainty about the absolute and relative contribution of dust from different source areas and landforms. Dust sources are mainly consid

We analyze an influence of radioactive decay and kinetic effects on the rate of trace gas scavenging due to adsorption by an ensemble of solid porous nanoparticles. The size of nanoparticles is comparable to the mean free path in the air at normal co

This survey includes, mainly, investigations that were published during recent years and a few earlier studies that were not included in the review by the same authors published in 2012. The survey covers analytical, numerical and experimental studie

On the basis of generalization of the Florence model to several ceramic layers, it is proved that arranging the ceramic plates in order of increasing material density implies the maximum the ballistic limit velocity of the armor in comparison with ot

Flat sand beds subjected to wind stress are unstable, and the wind action results in two types of aeolian sand ripples: normal ripples and megaripples. The distinction between the two types is based on two characteristics: i) the normal ripple patter
