Abstract
1-(Phenylamino-1,3,4-thiadiazol-5-yl)-3-phenyl-3-oxopropan (PTPO) was selected as the investigated material for studying the protection performance for mild steel in 1 mol L-1 hydrochloric acid solution. The inhibitor was assessed using weight loss measurements complemented with morphological analytical techniques and density functional theory (DFT) modelling. The PTPO demonstrated significant inhibitive efficacy of 95.4% in the presence of 500 ppm at 303 K. The protection efficiency increases with the concentration increasing from 100 to 500 ppm, and no significant effect after 500 ppm. Furthermore, gravimetric findings reveal that the protection efficiency at 500 ppm PTPO increases with immersion period and increasing temperature (303-333 K), due to the effective adsorption of PTPO on the mild steel surface, and the protection efficiency value is 95.8% at 48 h of exposure and 95.4%, 95.4%, 95.7% and 95.9% at 303, 313, 323 and 333 K, respectively. The adsorption of PTPO on the mild steel surface obeyed the Langmuir adsorption isotherm model and revealing the mode of chemisorption adsorption. According to the DFT calculations, protection by PTPO is essentially performed by the heteroatoms in the inhibitor molecules which represented the adsorption sites, and the aromatic rings increase the electrostatic interaction between the PTPO molecules and the mild steel surface. The surface morphological studies, weight loss measurements, and DFT computational studies are in good agreement and that the selected corrosion inhibitor is adsorbed on the mild steel surface to form a protected layer on the surface of mild steel against the hydrochloric acid solution.

Authors: Rebak R.B. 
Published: April 2022

Abstract
Nuclear power is a significant source of clean energy that can be used to mitigate climate change. In the western world, the average life of light-water power-reactors is increasing because no new reactors are being connected to the grid. In order to extend the life of the existing reactors innovative materials are being considered for the fuel of the reactors. The newer materials would be more resistant to a loss of coolant accident and allow for longer times between refueling plus permitting overall extended burn-ups, which will make the reactors safer and more economical to operate. This never used before in reactor materials include cladding concepts such as: 1) coated zirconium alloys, 2) monolithic iron-chromium-aluminum alloys, and 3) silicon carbide composites.

Authors: Aloshyna Oksana 
Published: April 2022

The purpose of the scientific article is to reveal the process of restoration and normalization of the activities of orthodox fraternities on the territory of the Right-Bank of Ukraine in the second half of the XIX – early XX ­centuries. Scientific novelty – for the first time the article analyzes the process of restoration and regulation of the orthodox fraternities on the basis of little-known archival documents, published materials and periodicals. It was found that the Russian government, in the legislative document «Basic rules for the establishment of orthodox church fraternities», defined the principles of establishment, functioning and all further activities of orthodox fraternities in the controlled territories. The difficult financial situation affected the church fraternity, due to lack of funds, were not able to fully implement the planned tasks. This led to the fact that in the late nineteenth century some fraternities ceased their activities. It is established that in connection with such circumstances, the church authorities made significant efforts to intensify and restore the activities of these organizations in the early XX century. The church leadership developed new models of statutes governing the activities of church fraternities. As a result, a number of decisions were made to intensify the multi-vector activities, to promote the establishment of new fraternities. The issues of the activity of the fraternities were repeatedly discussed at the congresses of the clergy of the western provinces of the Russian Empire, at which the priority directions of educational work were proposed.

Published: April 2022

The goal of the paper is to characterize materials from Department of manuscripts of Vasyl Stefanyk Lviv National Scientific Library of Ukraine dedicated to the history of Ukrainian displaced persons after World War II. Source criticism going to be the main methodological aspects of the presented research. The research on post-war displaced persons is quite popular in both Ukrainian and foreign historiography and that is why the paper will add some new information to this topic. Among domestic researchers of this problem it is worth noting the monograph by O. Podobed, which studies the cultural life of Ukrainians in DP camps. N. Sydorenko is engaged in the study of the camp press. Lviv researcher L. Holovata also pays attention to this issue in her articles. The activities of the Soviet repatriation commission are closely connected with the history of Ukrainians in the camps of postwar Europe. L. Khromeichuk and A. Andreev published papers dedicated to the USSR’s attempts to «bring» its citizens home. About a dozen of Ukrainian archival institutions store primary sources to the history of Ukrainian DP camps. And now the Department of manuscripts of Vasyl Stefanyk National Scientific Library of Ukraine can be added to that list. The topics dedicated to the history of Ukrainian DPs are still incomplete in historiography and revealing of a new archives and documents will do much help for future researches. Conclusion. Most of the materials for studying the history of Ukrainian DPs are stored in the personal archive of Mykhaylo Demkovych-Dobryansky (Fond # 298). Documents related to the movement of the fundraiser to the United Kingdom from the DP camp are available for researchers. Also within the fond #298 are collection materials of Stepan Baran who took an active part in a life of Ukrainian DP camps. Other materials could be found in the personal poet Canadian journalist A. Bedriy and 1917‒1921 Ukrainian revolution military activist I. Hnoyovyi.

Published: April 2022

Fungsi LPMK di Kelurahan Bangsal Aceh Kecamatan Sungai Sembilan Kota Dumai masih tetap berjalan walaupun belum sepenuhnya berjalan sesuai dengan amanat Perda Kota Dumai nomor; 04 tahun 2007, untuk itu keberadaan LPMK di Kelurahan Bangsal Aceh dalam memerankan fungsinya adalah untuk menciptakan pelaksanaan fungsi LPMK yang optimal, maka LPMK Bangsal Aceh harus terlebih dahulu dapat memantapkan dan memaksimalkan peran dan kedudukan LPMK yaitu sebagai mitra pemerintahan kelurahan dalam menampung dan mewujudkan aspirasi serta kebutuhan masyarakat di bidang pembangunan. Agar pelaksanaan kegiatan pembangunan bisa berjalan lebih optimal dan menyeluruh di wilayah kelurahan Bangsal aceh maka LPMK dituntut untuk lebih memberdayakan fungsi dalam kendala yang dihadapi sesuai dengan amanat Perda Kota Dumai nomor 04 tahun 2007, tentang Lembaga kemasyarakatan dikelurahan, dan tentunya harus saling berkoordinasi dengan pihak Pemerintahan Kelurahan dan masyarakatnya. Metode Penelitian yang digunakan dalam penelitian ini yaitu metode penelitian kualitatif yang bermaksud sebagai jenis penelitian yang temuan-temuannya tidak diperoleh melalui prosedur statistik atau bentuk hitungan lainnya. Kami menilai kurang seriusnya pihak LPMK menaggapi permaslahan ini, karena untuk sama-sama kita ketahui bahwa Ketua LPMK juga sebagai ketua Mesjid dalam artian ada dua tugas yang diemban oleh pak Amin, hal ini tentu akan menyita banyaak waktu ditambah lagi hubungan kerja intern LPMK kurang berjalan dengan baik. Jadi harapan saya LPMK harus dinakhodai oleh orang yang berkomitmen tinggi terhadap lembaga yang dipimpinnya tidak bisa setengah komitmen, kalau mau LPMK ini tetap eksis ’’

Two rare minerals were found in the sublimates of a natural coal fire at the Fan-Yagnob coal deposit (Tajikistan) – bonazzite As4S4 and alacranite As8S9. Bonazzite occurs as orange, orange-red rhombic tapered crystals, both skeletal, block, and full-faceted, from 0.1 to 1.5 mm in size. Bonazziite grows on realgar crystals or on a matrix, composed of amorphous As2S3. The association contains sal-ammoniac and ermakovite (NH4)(As2O3)2Br; crystals of the latter also grows on bonazziite. In transmitted light in thin sections, bonazzite is yellowish-brown, biaxial (+). Dispersion is strong, v > r. 2Vmeas. = + 60(5)°. Refractive indices are significantly higher than n = 2.05. In reflected light, it is gray with intense internal reflections ranging from yellow-green to red. Digests in 5M KOH, producing brown colored spots. The unit cell parameters from X-ray powder data are as follows: a9.972(5), b 9.435(3), c 8.870(6) Å, β 102.25(4) º, V 815(1) Å3. The X-ray ratio b : c= 1.063, morphological ratio (if to assign the symbol {111} to the most developed face) from the results of goniometric measurements from 0.817 to 0.870. Indicing of this facet, applying X-ray cell parameters leads to irrational symbols.Bonazziite crystals are assumed to be paramorphoses on a related phase with some different cell parameters. Measured density (g/cm3) 3.57(1), calculated 3.52. Chemical analysis by electron microprobe using EDS (12 points), As 69.01, S 29.86, Se 0.47, total 99.34 wt.%. The empirical formula is As4.01S3.96Se0.02. Adjacent realgar does not contain Se at the sensitivity level of the microprobe analysis. Powdery yellow As-sulfide sometimes develops on realgar, it also grows as rhombic brittle crystals, similar to those of bonazzite. X-ray powder data shows, it is close to alacranite with cell parameters a 9.90(5), b 9.58(5), c 9.11(5) Å, β 101.6(6) º, V 847(5) Å3.The growth of bonazzite could have been originated by a local increase in temperature (but no more than up to 320 °C – the upper temperature limit of stability of the realgar) and/or Se occurence in the gas precipitates, which played the role of a stabilizing impurity that caused the growth of bonazzite on the realgar. A local change in the thermal regime probably led to the appearance of related alacranite.

ABSTRACTThis study aims to examine financial problems, namely the effect of liquidity ratios, profitability, and activity on bankruptcy. The sample used is 60 companies that focus on one sector, namely the transportation sector for the 2017-2020 period. The test was carried out using multiple linear regression. The regression results show that the liquidity ratio as measured by the current ratio has a significant effect on bankruptcy, the profitability ratio as measured by net profit margin does not have a significant effect on bankruptcy, and the activity ratio measured by total asset turnover has a significant effect on bankruptcy. This research can be used by companies to indicate a decrease in financial problems before bankruptcy. The limitation of this study is that it only uses three independent variables such as the current ratio, net profit margin, and total asset turnover. In addition, this study only examines one sector, namely the transportation sector.Keywords: Liquidity Ratio, Profitability, Activity, and Bankruptcy
CONSTRUCTION OF EFFICIENT PLANETARY GEARS BASED ON THE MATRIX METHOD OF STRUCTURAL ANALYSIS
Authors: Tret'yakov Vladimir 
Published: April 2022

The study objective is to show the possibilities of the matrix approach in solving problems of analyzing structural properties and developing efficient structures of mechanisms.
The task to which the paper is devoted is to define the structural characteristics of planetary gears with one external and one internal engagement and to improve their structures.
Research methods. The paper uses a matrix method for analyzing the structural properties of the mechanism and modifying its structure, which is based on describing the mobility of kinematic pairs, links, kinematic chains, mechanisms using mobility matrices and the use of matrix equations.
The novelty of the work. Matrix equations are proposed that make it possible to conduct a structural analysis of independent closed circuits of complex mechanisms consistently. In contrast to the algebraic method, using a matrix approach, it is possible not only to find local and general mobility, determine the number of redundant connections, but also to find which mobility is missing.
Study results. The analysis showed that the planetary gears under consideration have redundant connections and mobility in the gears, leading to point contact of the teeth and uneven load distribution in planetary pinions. Proposals have been developed to eliminate redundant connections identified in the mechanisms.
Conclusions. The study conducted on the example of planetary gears shows that the matrix method of structural analysis is an effective means of identifying redundant connections and a tool that simplifies the search for technical solutions to eliminate them.

Published: April 2022

The paper presents the results of experimental studies of 3DMP synthesis with various shaping paths of the wire feedstock. The necessity of using oscillating feedstock movements in order to increase the stability of the welding process and prevent shape defects is established. Recommendations are given for using the path of oscillating movements depending on the width of the synthesized walls of samples. The quality of the synthesized material are studied and a few pores with sizes of 5...25 microns and 5…13 (sawtooth and U-shaped oscillation respectively) are discovered with the total pore content of 0.016% and 0.01% on the area under study. The study objective is the technological support of the quality parameters of the part synthesized by WAAM-method by controlling the shaping feedstock path depending on the geometric parameters of the part. The problem to which the paper is devoted is to identify the most optimal paths of feedstock during part synthesis while ensuring the quality parameters of the deposited layer (porosity). Conclusions: for the synthesis of wire parts by WAAM-method, it is possible to apply sawtooth and U-shaped feedstock oscillation paths with a recommended wall width of 6...20 mm, grown in the same technological cycle with oscillating feedstock path. The appropriateness of the choice of the oscillation path depends on the geometric parameters of the product.
Keywords: technology, surfacing, synthesis, 3DMP, WAAM, feedstock, path, oscillation, quality.
