Opis:
Perchlorate complexes of d-metals with tetrazole-containing ligands are proposed for application both as explosives for safe initiation systems and as modifers of burning rate for propellants. However, the problem of compatibility of organic polynitro compounds with the complexes has not yet been solved. In the present article the results of investigation of the infuence of perchlorate complexes of cobalt, copper and nickel with 1,5-pentamethylentetrazole as a ligand on thermal decomposition of energetic materials ranging from 1,1-diamino-2,2- dinitroethylene (FOX-7), to cyclic cyclotetramethylenetetranitroamine (HMX) and caged hexanitrohexaazaizowurtzitane (CL-20) have been reported. Thermal stability of the individual compounds and their mixtures with coordination complexes has been assessed on the basis of differential thermal analysis and the study of ignition temperatures after 5-second delay. The fraction of the complexes in the formulations with polynitro compounds amounted to ~10%.

Opis:
The paper presents the results of researches of temperature variations during flat peripheral grinding. It is shown that the temperature variations of the workpiece can reach 25...30% of the average values, which can lead to some thermal defects. A nonlinear two-dimensional thermophysical grinding model is suggested. It takes into account local changes in the cutting conditions: the fluctuation of the cut layer and the cutting force, the thermal impact of the cutting grains, and the presence of surface cavities in the intermittent wheel. For the numerical solution of the problem, the method of finite differences is adapted. Researches of the method stability and convergence are made, taking into account the specific nature of the problem. A high accuracy of the approximation of the boundary conditions and the nonlinear heat equation is provided. An experimental verification of the proposed thermophysical model was carried out with the use of installation for simultaneous measurement of the grinding force and temperature. It is shown that the discrepancy between the theoretical and experimental values of the grinding temperature does not exceed 5%. The proposed ther-mophysical model makes it possible to predict with high accuracy the temperature variations during grinding by the wheel periphery.

Opis:
In order to limit dust transfer during the operations of material transportation at the factories of the construction industry, factories of the mineral and raw materials complex employ special dust suppression bunkers. These devices are structures located above a railway hopper (either a truck body or a conveyor). Through the input portal of the device, the transported material is transferred. Dusting can also be carried out under the bunkers from the side of the hopper, into which the material is poured. The design of dust suppression bins should be accompanied by a simulation of dust propagation processes. The simulation should be carried out in order to minimize the dust emissions and to select the optimum locations for the dust suppression sprayers.

Opis:
Developing devices for dust suppression one should consider important factors, such as the size distribution of transferred dust, duration of exposure in residential areas. Often the total amount of dust emissions may exceed the estimated figure for maximum permissible emissions, but their share transferred in sanitary protection zone of dust is negligible. Tailing dump of Kovdor MPE is one of the largest in Russia. The construction of dust dispersion halos was performed using a universal program calculation of air pollution “Ecolog” (Russia). Based on a comparison of dispersed compositions tails similar in composition tailing dumps in Russia, it can be concluded that in the beach area of the Kovdor dump share of dust tranfered to the territory of settlements has ranged from 10 to 40%. It was found that the maximum diameter of the particles carried by the territory of the city under consideration is 50 microns. We can conclude that under the conditions of the object the development of special devices for dust suppression is required.

Opis:
The construction of subway stations is inevitably accompanied by the formation of a large amount of waste that is extracted from the underground workings by rock. When the waste is transported, the air is polluted with the exhaust gases of the dump trucks, some of the waste can stay on the road surface, the use of dump trucks increases the load on the roadway, the disposal of waste at landfills harms the environment, and enterprises pay fees for the transportation as well as placement of the waste. The article deals with the waste from the construction of new stations in the Saint-Petersburg subway. In order to determine the possibility of using waste in the municipal economy, a comprehensive analysis of this waste was carried out, including determination of moisture content, acidity, total carbon content, as well as chemical and granulometric composition. On the basis of the study results, it was established that the waste in question belongs to the hazard class 5, which enables to use it as a component of the soil mixture. Afterwards, the hazard class 5 was confirmed by the method of bioassay based on the determination of water toxicity by changing the optical density of the Chlorella algae culture.

Opis:
The results of X-ray, scanning electron microscopy and atomic force microscopy studies of near-surface regions of (111) $Hg_{1-x}Cd_{x}Te$ (x = 0.223) structures are presented. These structures were obtained by low-energy implantation with boron and silver ions. TRIM calculation of the depth dependences of impurity concentration and implantation-induced mechanical stresses in the layer near-surface regions has revealed that the low-energy implantation of HgCdTe solid solution with elements of different ionic radiuses $(B^{+}$ and $Ag^{+})$ leads to the formation of layers with significant difference in thickness (400 nm and 100 nm, respectively), as well as with maximum mechanical stresses differing by two orders of magnitude (1.4 × $10^3$ Pa and 2.2 × $10^5$ Pa, respectively). The structural properties of the $Hg_{1-x}Cd_{x}Te$ epilayers were investigated using X-ray high-resolution reciprocal space mapping.

Investigations of the photoluminescence of PbS-EuS superlattices deposited on (111)BaF$\text{}_{2}$ substrates are presented. Quantum-size and deformation effects in photoluminescence spectra are observed. The strain-induced gap shift and valence-band offset is determined from experimental results. A strong stimulated photoluminescence with relatively low threshold was observed. It was found that the photocarriers generated in EuS barrier strongly affect the population of PbS subbands.
