AbstractThe possibility of observing, in the upper layers of the Earth’s atmosphere, the polarization of the HeI helium line, with a wavelength of 5015 Å, is studied. Several helium lines are observed in the visible region. The polarization of HeI neutral helium lines can have a shock character and will occur when plasma is affected by accelerated ...

AbstractLow-velocity detonation in mixtures of ammonium perchlorate and fuel additives in high relative density charges is an interesting subject for the scientific research, with potential for practical applications in pulse nozzle and projective setups. However, information about the process is scanty and mainly concerns the measurements of the w...

AbstractThe detonability of the emulsion explosive based on ammonium nitrate sensitized with glass microspheres has been studied. It has been confirmed that the dependence of the critical diameter of detonation on porosity (density) may be U-shaped with a low content of an inert additive. Analysis of the data obtained and those available in the lit...

AbstractThe kinetics of thermal decomposition of 2,4-bis(dimethylamino)-6-trinitromethyl-1,3,5-triazine has been studied in melt and in a dilute solution of dinonyl phthalate by manometric and gravimetric methods. The reaction has proven to be self-accelerated. The additives of N-phenylmorpholine significantly have accelerated the decomposition. A ...

Abstract—Zero-point energies (ZPEs) of intermolecular, noncovalent vibrations and isotope effects, induced by noncovalent interactions, are computed for complexes of lipoxygenase, which induces enzymatic oxidation of arachidonic acids in living organisms. For complexes with hydrogen, water, methane, and ethylene molecules noncovalent isotope effect...

AbstractThe critical conditions for the transformation of a plane detonation wave into a cylindrical detonation wave are experimentally found. For mixtures of oxygen with hydrogen or methane, the geometric conditions are determined for detonation initiation in a cylindrical gap at various diameters of the orifice through which the plane detonation ...

AbstractThe article reviews methods for the computer analysis and detection of so-called ionospheric earthquake precursors. It is shown that the applied techniques lead to quantitatively incomparable results due to the differences in determination of a reference undisturbed variation and in quantitative criteria of considering disturbances anomalou...

AbstractThe effect of the reaction between methyl radical and molecular oxygen on autoignition of various carbohydrates at temperatures above 1300 K is studied using numerical simulation. Calculations using the detailed kinetic mechanism showed that the interaction between CH3 and O2 is essential for autoignition of methane and acetone, while havin...

AbstractThe conceptual provisions and strategical aspects of the monitoring of the chemical composition of the atmosphere at manned spacecrafts and space stations which can be used in the execution of long-term and interplanetary space flights are proposed and substantiated. The major risk factors of the change in the composition of the atmosphere ...
