Abstract
New silicate-germanates (K2.9Cs0.1)(Sc0.7In0.3)[(Si2.95Ge0.05)O9]·H2O and (K2.16Cs0.84)Bi[(Si0.5Ge0.5)3O9]·H2O have been synthesized in multi-component systems under mild hydrothermal conditions. The new compounds are classified as new representatives of close related K3ScSi3O9·H2O parent structure, sp. gr. Pmn21. Their structural and isomorphic peculiarities are compared with it as well as with earlier investigated K1.46Pb1.54Сa[(Ge0.23Si0.77)3O9](ОН)0.54·0.46Н2О. Together with other known compounds, silicate-germanates form the extensive family A3M[T3O9]·H2O, A = K, Cs, Ca, Pb; M = Ho, Sc, Lu, Tb, Er, Y, Bi, Pb, In; T = Si, Ge, with a mixed microporous framework combined of M-octahedra and T-tetrahedra. Large alkali metal or/and Ca, Pb cations fill broad framework channels with cross-section up to 7.3 Å. Because of wide isomorphic substitution in the channels, and in tetrahedra and octahedra, ion exchange properties in the family are expected. Due to polar symmetry, all the crystals possess second-order nonlinearity which was confirmed with positive SHG tests for four compositions. Powder SHG experiments demonstrated moderate second harmonic intensities of order of α-quartz standard signals.

Abstract
A metastable polymorph of Ti3Sn (called c-Ti3Sn) exhibiting the cubic Cr3Si-type structure was prepared by a mechanochemical route. At temperatures of about 450 °C, it transforms to the well-known hexagonal phase (Ni3Sn type, called h-Ti3Sn). 0.5% of iron was incorporated into the material originating from the steel beaker and the steel balls. However, quantum-chemical calculations show that this should not lead to a stabilization of the Cr3Si type. c-Ti3Sn shows a single signal at an isomer shift of δ = 1.70(1) mm s−1 in its 119Sn Mössbauer spectrum at 78 K.

Fluid catalytic cracking (FCC) is a method of cracking vegetable oils into simpler fractions and green fuel oils. One component of the FCC system is the FCC furnace. The FCC furnace is where the combustion process occurs and provides high heat transfer throughout the FCC system, especially for heating the reactor. The reactor temperature is the catalyst cracking temperature. The cracking temperature of the catalyst depends on the feed oil used in the cracking process, such as crude palm oil at 450‒550 °C or crude bio-oil at 300 °C. The fuel for heating an FCC furnace is usually coal. To reduce coal, we use a mixture of Azolla microphylla biomass with biochar and bio-oil from goat manure. The aim of this study was to analyze the mixture of Azolla microphylla biomass with biochar and bio-oil from goat manure to obtain sufficient furnace temperature to heat the FCC reactor, perform analytical calculations to obtain the volume of flue gas formed from the combustion reaction. We conducted two experiments; the first experiment used a mixture of 1 kg of Goat Manure Biochar (GMBC) with 0.5 kg of Azolla microphylla and the second experiment used a mixture of one kg of GMBC with 0.5 kg of Azolla microphylla plus 300 ml of Goat Manure Bio-oil (GMBO). A fuel mixture of one kilogram GMBC with 0.5 kg Azolla is not effective in combustion because the maximum temperature in the furnace is 177 °C but the fuel mixture of one kg GMBC, 0.5 kg Azolla and 300 ml GMBO has a furnace temperature of 472.75 °C, which can heat the stripper up to 313.25 °C so that cracking can occur in the raw bio-oil. Analysis of combustion results showed an increase in total CO2 volume from experiment one and experiment two of 0.966

Experimental studies have proven the effectiveness of the use of the herbal dietary supplement "Immunocort" in the technology of rennet cheese "Mozzarella Ukrainian". "Immunocort" is an herbal preparation that contains a balanced complex of immunoactive plants aimed at strengthening the immune system and eliminating immunodeficiency. The composition of the dietary supplement includes astragalus herb, echinacea root, Damascus blackberry seeds, currant leaf, string grass, Uncaria bark, and ant tree bark.
Based on organoleptic and physical-chemical studies, it was established that the best option in the manufacture of "Mozzarella Ukrainian" cheese is to add to the normalized mixture before its pasteurization of the "Immunocort" supplement in the amount of 3 % by weight of the normalized mixture.
A study was conducted on the effect of the coagulation temperature and pasteurization temperature on the synergistic properties of the cheese clot. These indicators confirmed the significant importance for the transition of solids into whey in the process of making rennet cheese "Mozzarella Ukrainian" with the bio additive "Immunocort". It was found that with an increase in temperature, there was a decrease in the syneretic ability of cheese clots. The efficiency of using solids increased with increasing pasteurization temperature. The relatively low content of dry substances in whey at high pasteurization temperatures can be explained by the denaturation of whey proteins and their transition to a cheese clot. The best results were achieved at the pasteurization temperature (86±2) °C and the coagulation temperature (32±2) °C.
The data obtained could make it possible to manage the process of making new types of cheeses with vegetable additives, depending on the specific conditions and requirements for the product

Published: March 2023

The coronavirus causing the Covid-19 pandemic has been experienced by us since 2020, which has led to an increase in the use of disposable medical masks in Indonesia and even worldwide. Polypropylene is a thermoplastic polymer used as the main ingredient in medical masks that takes more than 25 years to decompose in landfills. This research offers an innovative way to use medical mask waste in high-performance concrete. The resulting medical mask waste is subjected to a sterilization process and cut into fibers to analyze the effect of its addition on the compressive strength and splitting tensile strength of high-performance concrete. The research began with testing the physical and mechanical properties of the materials, designing a concrete mix using the absolute volume method, and taking samples for compression and splitting tests. The variation in the ratio of water-cement and pozzolanic materials w/(c+p) is 0.32. As a result, the compressive strength of concrete increased with a fiber size of 5×0.5 cm and 2×0.5 cm. An increase is up to 7 % with an optimum value of 72.37 MPa with a fiber size of 2×0.5 cm and a content of 0.15 %. However, there was a decrease in the compressive strength with a 5×1 cm mask fiber size. The overall split tensile strength value of all variations in waste fiber size and content increased with an optimum value of 7.29 MPa at 0.20 % fiber content with a fiber size of 5×0.5 cm. This indicates that polypropylene fibers from medical mask waste have a positive effect on high-performance concrete, namely improve the properties of concrete with a low tensile strength, which is expected to inhibit the propagation and reduce the size of cracks in reinforced concrete structures

The quality and comfort of clothing for people engaged in mountain tourism are influenced by the pack of clothing materials, which determine their durability and heat resistance. In practice, wear resistance and thermal insulation of clothing materials are evaluated by standard methods for single-layer materials. To solve the problem of studying the wear resistance and heat resistance of a clothing pack, we developed an experimental setup for studying the wear resistance of the clothing pack under the influence of cyclic loads and an installation for determining the heat-shielding properties of the pack of clothing materials, allowing you to reproduce both the temperature of the underwear space, as well as environmental factors.
By studying the influence of wind flow, humidity and ambient temperature on the heat-shielding ability of packages of various compositions, the most rational package of clothing for mountain tourism was determined. The selected package provides a comfortable state of a person in the absence of air permeability and at a wind speed of 5 m/s; and at wind speeds of 10 m/s and 15 m/s, the temperature of the underwear space decreases. The heat protection of the clothing package is influenced by the breathing of the athlete’s body during movements. So, at ambient temperature Tok=20 °C and humidity within 60‒70 % when the breathing simulator was turned on in the underwear space, Tpp=26 °C, W=62 %, and when it was turned off, Tpp=27 °C, and the humidity value did not change.
The developed experimental installations and research methods can be recommended for use at the design stage in the production laboratories of enterprises producing mountain sports clothing

Published: March 2023

In order for enterprises not to suffer significant losses by repurposing their activities for the manufacture of products attractive at certain points in time, it is necessary to take into account the compatibility of resource mutual support of the business processes they perform when forming the product range. Such compatibility and interaction should ensure the long-term efficiency of the enterprise and the strategic attractiveness of its products on the market.
Accordingly, the object of this study is the process that forms a rational resource base for effective long-term competitive development of the enterprise through the formation of an additional effect. Within the framework of the formed approach, the expediency to use the coefficient of managerial efficiency to choose the necessary source of resource provision (own production or alternative attraction of the necessary resources from an attractive stakeholder) has been proven.
The proposed recommendations should be applied to enterprises that use a significant number of parts, assemblies, and components for production; therefore, they have been tested on the activities of a machine-building enterprise. The results confirmed the feasibility of independent production by the studied enterprise of the relevant types of raw materials and the provision of certain services. This made it possible, by rationalizing the assortment policy of the enterprise, to create a closed production cycle and reduce, thereby, its dependence on third-party enterprises, which is extremely relevant under wartime conditions. In addition, the implemented measures made it possible to increase the volume of production of a particular type of product (vacuum pumps) by 10 %, reduce the reserve of production capacity, and ensure the stability of competitive advantages by increasing the service life and quality of individual components of the existing goods of the studied enterprise

This paper substantiates the expediency of conducting scientific research into the formation of the concept of tax benefits within the framework of technology transfer, which would meet the strategic interests of the state and business needs. The study is aimed at finding the optimal level of tax benefits within the existing means of state support for the introduction of new technologies.
It is proved that the effectiveness of preferential taxation depends on the area of implementation, the level of the economy, the sustainability and immutability of tax legislation. Normative means of formation of a system of preferential taxation of innovation activity and technology transfer within the legal system are proposed, namely:
1) a candidate for tax benefits from the state must undergo a special permitting procedure for confirming its legal status;
2) the system of tax benefits for participants in innovative relations and technology transfer should include two options for tax systems. On the one hand, there should be a system of tax benefits based on a preferential rate of income tax, value added tax, and an increased level of depreciation. On the other hand, a special type of simplified taxation system should be implemented, which should contain special (preferential) rates for paying a single tax;
3) the types of activities that can be carried out by business entities wishing to receive tax benefits should be limited by law. Such activities should include only those that carry out activities in the field of social production of goods.
The results of the study take into account the world experience of using similar means of support and can be used in the formation of regulatory means for regulating these relations

The problem that is solved in the research is to increase the efficiency of decision making in management tasks while ensuring the given reliability, regardless of the hierarchy of the system. The object of the research is the decision making support system in the field of democratic civilian control over the security and defense sector (FDCCSDS). The subject of research is the decision making process in management tasks using fuzzy cognitive maps and evolving artificial neural networks. The hypothesis of the research is to increase the number of sources of information about the components of the FDCCSDS, with restrictions on the efficiency and reliability of decision making. The research proposed a method for evaluating the information and analytical provision of public administration in FDCCSDS. It was established that the proposed method has a higher efficiency compared to the known ones by an average of 40 %, compared to the methods used to evaluate the effectiveness of strategic management decisions. The specified method will make it possible to assess the state of information and analytical provision of public administration in the FDCCSDS and to determine effective measures to improve efficiency. The method will allow to analyze possible options for the development of FDCCSDS in each phase of development and moments in time when it is necessary to carry out structural changes that ensure the transition to the next phase. At the same time, subjective factors of choice are taken into account while searching for solutions, which are formalized in the form of weighting coefficients for the components of the integral criterion of efficiency. The specified method allows to increase the speed of assessment of the state of information and analytical support of the FDCCSDS, to reduce the use of computing resources of and decision making support systems, to form measures aimed at increasing the efficiency of information and analytical support

Published: March 2023

Internet of things (IoT) becomes the most popular term in the recent advances in Healthcare devices. The healthcare data in the IoT process and structure is very sensitive and critical in terms of healthy and technical considerations. Outlier detection approaches are considered as principal tool or stage of any IoT system and are mainly categorized in statistical and probabilistic, clustering and classification-based outlier detection. Recently, fuzzy logic (FL) system is used in ensemble and cascade systems with other ML-based tools to enhance outlier detection performance but its limitation involves the false detection of outliers. In this paper, we propose a fuzzy logic system that uses the anomaly score of each point using local outlier factor (LOF), connectivity-based outlier factor (COF) and generalized LOF to eliminate the confusion in classifying points as outliers or inliers. Regarding human activity recognition (HAR) dataset, the FL achieved a value of 98.2 %. Compared to the performance of LOF, COF, and GLOF individually, the accuracy increased slightly, but the increase in precision and recall indicates an increase in correctly classified data and that neither true nor abnormal data is classified wrongly. The results show the increase in precision and recall which indicates an increase in correctly classified data. Thus, it can be confirmed that fuzzy logic with input of scores achieved the desired goal in terms of mitigating cases of false detection of anomalous data. By comparing the proposed ensemble of fuzzy logic and different types of local density scores in this study, the outcomes of fuzzy logic presents a new way of elaborating or fusing the different tools of the same purpose to enhance detection performance

Published: March 2023

Aim. To study the density and dynamic viscosity of the mixed solvents propylene glycol (PG) – macrogol 400 (M400), to calculate their excess values and excess activation parameters of viscous flow, to evaluate the features of the structure of the mixed solvents and its influence on the in vitro release of PG and M400.
Materials and methods. The mixed solvents PG - M400 were studied over the entire concentration range at temperatures from 293.15 to 313.15 K. The density and dynamic viscosity were determined, and the excess density, excess dynamic viscosity, activation parameters of viscous flow, and excess activation parameters of viscous flow were calculated. The in vitro release of PG and M400 from the mixed solvents was studied using vertical diffusion cells. The content of PG and M400 in the receptor medium was determined by gas chromatography using validated analytical procedures. The release rate, cumulative content, percentage of released PG or M400, coefficients of correlation and coefficients of determination were calculated.
Results. The isotherms of excess density and excess dynamic viscosity of the mixed solvents PG-M400 pass through a maximum. The enthalpy makes the main contribution to the free activation energy of the viscous flow. The excess free energy is positive and has small values; the values of the excess entropy and excess enthalpy are negative, and the isotherms have the minimum at PG concentrations of 70‑75mol %. The release parameters of M400 are greater in binary mixtures where the M400 structure predominates. At PG content of ~75 mol %, the release parameters for PG and M400 are identical. With the increase in PG content above 75 mol %, when the PG structure predominates in the system, the release parameters of PG increase dramatically, and the release parameters of M400 decrease sharply.
Conclusions. The structure of the binary system PG – M400 depends on its composition. Based on the isotherms of excess activation of viscous flow, it is possible to differentiate the areas where the structure of PG or the structure of M400 dominates, or the mixed structure of the binary solvent prevails. The in vitro release parameters for PG and M400 depend on the structure of the mixed solvents. The greatest difference in the release parameters of PG and M400 was observed in the area where the structure of PG dominates
