This Article Purpose is to determine specifics of damage to cotton jer-sey, arising from a point-blank shot from a nickel-plated “Fort-12RM” pistol, equipped with .45 Rubber cartridges into  dressed simulator of a human torso made of ballistic gel. For achieving this goal, 12 human torso simulators were made, dressed in cotton T-shirts, with the subsequent firing of shots using a nick-el-plated “Fort-12RM” pistol equipped with .45 Rubber cartridges. The shots were fired from a distance, closely followed by examination of damage to cloth-ing using photographic and microscopic research methods. Obtained data and their comparison with the previously obtained research results when the shots were fired at the clothing samples, fixed in the frame made it possible to identify important differences and for the first time describe the phenomenon of internal muzzle imprint mark and volumetric muzzle imprint mark; while describing the internal muzzle imprint mark, specific deposition of additional factors of the shot (namely, soot), reminiscent of a candle flame was found. In addition, a double marker phenomenon was observed around the input gunshot injury on the inves-tigated human torso simulator. Most of  additional factors of the shot (in form of soot and dust particles of unburned gunpowder) were determined in wound channel. While carrying out the contact-diffusion method of research, small particles of nickel were determined around input fire damage to the simulator. The revealed differences require revision of the classical method of experimental shooting, while test samples of clothing are fixed in a frame or fixed in a similar way. An important stage in research formulation is to recreate the conditions as close as possible to real ones. The search for the most appropriate, efficient and simple method for carrying out such experiments is promising for ballistics

For the first time, it is shown that inhaled ambient air-dust particles settled in the human lower respiratory tract induce lung calcification. Chemical and mineral compositions of pulmonary calcium precipitates in the lung right lower-lobe (RLL) tissues of 12 individuals who lived in the Upper Silesia conurbation in Poland and who had died from causes not related to a lung disorder were determined by transmission and scanning electron microscopy. Whereas calcium salts in lungs are usually reported as phosphates, calcium salts precipitated in the studied RLL tissue were almost exclusively carbonates, specifically Mg-calcite and calcite. These constituted 37% of the 1652 mineral particles examined. Mg-calcite predominated in the submicrometer size range, with a MgCO3 content up to 50 mol %. Magnesium plays a significant role in lung mineralization, a fact so far overlooked. The calcium phosphate (hydroxyapatite) content in the studied RLL tissue was negligible. The predominance of carbonates is explained by the increased CO2 fugacity in the RLL. Carbonates enveloped inhaled mineral-dust particles, including uranium-bearing oxides, quartz, aluminosilicates, and metal sulfides. Three possible pathways for the carbonates precipitation on the dust particles are postulated: (1) precipitation of amorphous calcium carbonate (ACC), followed by its transformation to calcite; (2) precipitation of Mg-ACC, followed by its transformation to Mg-calcite; (3) precipitation of Mg-free ACC, causing a localized relative enrichment in Mg ions and subsequent heterogeneous nucleation and crystal growth of Mg-calcite. The actual number of inhaled dust particles may be significantly greater than was observed because of the masking effect of the carbonate coatings. There is no simple correlation between smoking habit and lung calcification.

S-N curve characterisation and prediction of remaining fatigue life are studied using polyethylene terephthalate glycol-modified (PETG). A new simple method for finding a data point at the lowest number of cycles for the Kim and Zhang S-N curve model is proposed to avoid the arbitrary choice of loading rate for tensile testing. It was demonstrated that the arbitrary choice of loading rate may likely lead to an erroneous characterisation for the prediction of the remaining fatigue life. The previously proposed theoretical method for predicting the remaining fatigue life of composite materials involving the damage function was verified at a stress ratio of 0.4 for the first time. Both high to low and low to high loadings were conducted for predicting the remaining fatigue lives and a good agreement between predictions and experimental results was found. Fatigue damage consisting of cracks and whitening is described.

Aluminum antimonide is a semiconductor of the Group III-V order. With a wide indirect band gap, AlSb is one of the least discovered of this family of semiconductors. Bulk synthesis of AlSb has been reported on numerous occasions, but obtaining a single phase has always proven to be extremely difficult. This work reports a simple method for the synthesis of single-phase AlSb. Subsequently, consolidation was done into a near single-phase highly dense semiconductor in a form usable for thermoelectric applications. Further, the thermoelectric properties of this system are accounted for the first time. In addition, the mechanical properties of the intermetallic compound are briefly discussed for a possibility of further use.

Introduction. The article presents the results of research of the geographical vocabulary of the Shilan dialect, one of the Erzya-Mordovian dialects of the Samara region, common among Erzya population of Shilan village in Krasnoyarsk region. The dialect belongs to rare Mordovian dialects of the Samara Volga region that were formed in the region since the middle of the XIX century, and therefore its research is of extra interest. Materials and Methods. The research methods are determined by the purpose and objectives of the study. The analysis of the geographical vocabulary of the Shilan dialect is carried out with the involvement of relevant items made in other Mordovian dialects of Samara region, adjacent territories of neighboring regions, as well as other territories of settlement of the Mordovians. Data on geographical vocabulary of the dialect introduced into research for the first time. The main source materials for the article is based on field studies in Silane village during the field seasons in 2017 and 2020, as well as in other Erzya-Mordovian and Moksha-Mordovian villages of Samara region and adjacent territories in 2015 – 2020. Results and Discussion. The study showed that the geographical vocabulary of the Shilan dialect of the Erzya-Mordovian language is significantly different from the corresponding lexical clusters in other dialects of the Mordovian region, which can be explained by natural geographical conditions surrounding Shilan village and the original composition of this lexical cluster of Erzya immigrants who founded this village. Conclusion. The analysis of the geographical vocabulary of the Shilan dialect allowed, on the one hand, to identify specific features of this cluster that distinguish it from the corresponding materials of other Mordovian dialects of the region, and, on the other hand, to identify common isoglosses between it and a number of the Erzya-Mordovian dialects of the Samara Volga region.

In the previous article, we analyzed the scope and features of the formation of fair value, which is entered into the Russian accounting of inventories and property, plant and equipment of non-budgetary sphere organizations (including healthcare organizations) thanks to the Federal Accounting Standards (FAS) 5/2019 “Inventories”, 6/2020 “Property, Plant and Equipment”, and 26/2020 “Capital Investments”. This article examines the valuation techniques and hierarchy of fair value of these assets. This study is all the more relevant since the fair value is entered into the Russian accounting of inventories and property, plant and equipment of non-budgetary organizations for the first time and it is still quite unusual for many domestic accountants. Analysis, synthesis, grouping method, comparison, analogy method, logical approach, and systemic approach were used as research methods. As a result of the research carried out, the article analyzes the fundamental issues in the field of valuation techniques and hierarchy of fair value of inventories and property, plant and equipment of non-budgetary sphere organizations (including healthcare organizations), identifies the most important problems in this area and presents recommendations for their solution.

A simple method to prepare a high-content rutin fraction from Forsythia koreana flowers (HRFK) is described. Rutin, isolated for the first time from the flowers, was identified from spectroscopic data including nuclear magnetic resonance, mass spectrometry, and infrared. As a result of HPLC quantitative analysis, the content of rutin was found to be 80.0 ± 0.02% in HRFK. Our previous study reported that F koreana MeOH extract (FK) significantly recovered alloxan-induced pancreatic islets in zebrafish. However, HRFK as well as rutin exhibited an enhanced anti-diabetic effect compared to FK in our latest experiments. In conclusion, HRFK, as well as rutin and FK, have potential as anti-diabetic agents.
