Published: June 2022

In wave propagation phenomena, time-advancing numerical methods must accurately represent the amplitude and phase of the propagating waves. The acoustic waves are non-dispersive and non-dissipative. However, the standard schemes both retain dissipation and dispersion errors. Thus, this paper aims to analyse the dissipation, dispersion, accuracy, and stability of the Runge–Kutta method and derive a new scheme and algorithm that preserves the symmetry property. The symmetrised method is introduced in the time-of-finite-difference method for solving problems in aeroacoustics. More efficient programming for solving acoustic problems in time and space, i.e. the IMR method for solving acoustic problems, an advection equation, compares the square-wave and step-wave Lax methods with symmetrised IMR (one-and two-step active). The results of conventional methods are usually unstable for hyperbolic problems. The forward time central space square equation is an unstable method with minimal usefulness, which can only study waves for short fractions of one oscillation period. Therefore, nonlinear instability and shock formation are controlled by numerical viscosities such as those discussed with the Lax method equation. The one- and two-step active symmetrised IMR methods are more efficient than the wave method.
EXPLICIT FIFTH-ORDER HYBRID METHODS FOR DYNAMICAL SYSTEMS WITH DELAY
Authors: Pechuk Vasiliy , Bondarenko Nataliya 
Published: June 2022

In the paper we consider the systems of delay differential equations, which are mathematical models of many technical processes with delay in time. An explicit fifth-order hybrid method for systems of delay differential equations for the variable step of numerical integration is constructed. This algorithm is based on the most commonly used explicit fifth-order Runge-Kutta methods for ordinary systems of differential equations and the construction of Newton polynomials for the prehistory of the model and Taylor formula. The basic principles of construction of such explicit hybrid methods of higher orders of convergence are given. An accurate estimate of the local error of numerical integration by this method is obtained.
This algorithm allows the use of numerical integration steps greater than the magnitude of the delay or procedures for adjusting the magnitude of the step depending on the calculation error. Such a problem of numerical integration of time-delay dynamical systems occurs when the time interval is large enough compared to the delay. Implicit continuous Runge-Kutta methods were previously used for numerical integration such problems, which complicated the numerical algorithm, because nonlinear systems of equations have to be solved at each step of numerical integration. The explicit hybrid method constructed by us for systems of delay differential equations is convenient for programming, has a high speed of calculation of numerical solution, in comparison with implicit methods for such models of problems. Also, this method has no restrictions on the magnitude of the delay, in contrast to the hybrid methods with decomposition in Taylor series for delay. The method obtained by us can be used to construct maps of dynamic modes in the study of regular and chaotic behavior of time-delay dynamical systems.
Study of changes in groundwater quality indicators during operation of water intake well
Authors: Khomutetska Tetiana , Arhatenko Tetiana 
Published: June 2022

Groundwater is one of the main sources of providing people with drinking water. However, during the period of operation of water wells, the quantitative and qualitative characteristics of groundwater change significantly. These changes depend on many factors of natural and man-made origin, in particular, depletion of reserves, conditions of operation and construction of wells, anthropogenic impact on the environment and so on. To assess the water quality of the underground source intended for water supply of one of the facilities in Kyiv, a number of studies of the quality of water extracted from a well 67 m deep were compared. Experiments conducted after the well in 2010 and 2021 were compared. The analysis of the obtained results showed changes in the indicators of groundwater quality during the well operation, which relate to water turbidity, color, total hardness, dry residue, total iron and manganese content.
In the current operating conditions of the water intake, the groundwater raised to the surface does not meet the current regulatory quality requirements, and therefore it needs to be purified before it is delivered to consumers. For this case and the need to provide water to a small facility, it is recommended to use the technology of deironing water by biological oxidation. The use of a bioreactor with an insoluble carrier and a contact-clarifying filter with expanded polystyrene loading is proposed. The technology has shown high efficiency in both laboratory and production conditions for local water mains.

Skin diseases in farm animals are most often caused by ectoparasites, which are complex with the host. Chorioptosis of cattle is caused by skin mites of the genus Chorioptes, Chorioptes Bovis, which occupy a significant place among ectoparasites and cause great economic damage to livestock, has become widespread. Effective control and protection of animals against chorioptosis requires the development of highly effective insecticides, the therapeutic and economic feasibility proven by experimental studies. The study aimed to study the therapeutic efficacy of modern drugs for chorioptosis of cattle, taking into account the method and frequency of use of chemicals and active substances that are part of them. Experimental testing of domestic and foreign drugs for Chorioptes Bovis: brovermectin 1 % (DR – ivermectin), sebacil 50 % (DR – foxim), neostomazan (DR – transmix, tetramethrin). The leading indicators of the effect of drugs were extensibility and intensity. According to the results of the studies, it was found that the most effective drugs for spontaneous chorioptosis of heifers were drugs brovermectin 1% and sebacil 50% with three times their use with an interval of 10 days. Their extensibility and intensity efficiency at 25 and 30 days, respectively, was 100%. With double use of these drugs, the therapeutic efficacy (EE and IE) decreased, and on the 60th day of the experiment, brovermectin was 1 % – 66.67 and 87.82 %, sebacil 50 % – 53.30 and 82.04 %, respectively. The use of neostomazan in chorioptosis patients did not lead to their complete recovery. With double use of the drug on the 60th day of the experiment, the indicators of extensibility and intensively were 40.0 and 89.59 %, with three uses – 60.0 and 89.59 %, respectively. The obtained research results recommend brovermectin 1 % and sebacil 50 % to effectively carry out treatment and prevention measures for chorioptosis in cattle.

In oral- and maxillofacial bone augmentation surgery, non-vascularized grafts from the iliac crest demonstrate better clinical performance than alveolar bone grafts. The underlying mechanisms are not fully understood but are essential for the enhancement of bone regeneration scaffolds. Synchrotron Radiation µ-CT at a pixel size of 2.3 μm was used to characterize the gross morphology and the vascular and osteocyte lacuna porosity of patient-matched iliac crest/alveolar bone samples. The results suggest a difference in the spatial distribution of the vascular pore system. Fluid simulations reveal the permeability tensor to be more homogeneous in the iliac crest, indicating a more unidirectional fluid flow in alveolar bone. The average distance between bone mineral and the closest vessel pore boundary was found to be higher in alveolar bone. At the same time, osteocyte lacunae density is higher in alveolar bone, potentially compensating for the longer average distance between the bone mineral and vessel pores. The present study comprehensively quantified and compared the 3D microarchitecture of intraindividual human alveolar and iliac bone. The identified difference in pore network architecture may allow a bone graft from the iliac crest to exhibit higher regeneration potential due to an increased capacity to connect with the surrounding pore network of the residual bone. The results may contribute to understanding the difference in clinical performance when used as bone grafts and are essential for optimization of future scaffold materials.

In this study, we propose a highly efficient robot platform for pollutant adsorption. This robot system consists of a flapping-wing micro aircraft (FWMA) for long-distance transportation and delivery and cost-effective multifunctional Janus microrobots for pollutant purification. The flapping-wing micro air vehicle can hover for 11.3 km with a flapping frequency of approximately 15 Hz, fly forward up to 31.6 km/h, and drop microrobots to a targeted destination. The Janus microrobot, which is composed of a silica microsphere, nickel layer, and hydrophobic layer, is used to absorb the oil and process organic pollutants. These Janus microrobots can be propelled fast up to 9.6 body lengths per second, and on-demand speed regulation and remote navigation are manageable. These Janus microrobots can continuously carry oil droplets in aqueous environments under the control of a uniform rotating magnetic field. Because of the fluid dynamics induced by the Janus microrobots, a highly efficient removal of Rhodamine B is accomplished. This smart robot system may open a door for pollutant purification.

Background: Thyroid hormones play a significant role in bone development and maintenance, with triiodothyronine (T3) particularly being an important modulator of osteoblast differentiation, proliferation, and maintenance. However, details of the biological processes (BPs) and molecular pathways affected by T3 in osteoblasts remain unclear.Methods: To address this issue, primary cultures of human adipose-derived mesenchymal stem cells were subjected to our previously established osteoinduction protocol, and the resultant osteoblast-like cells were treated with 1 nm or 10 nm T3 for 72 h. RNA sequencing (RNA-Seq) was performed using the Illumina platform, and differentially expressed genes (DEGs) were identified from the raw data using Kallisto and DESeq2. Enrichment analysis of DEGs was performed against the Gene Ontology Consortium database for BP terms using the R package clusterProfiler and protein network analysis by STRING.Results: Approximately 16,300 genes were analyzed by RNA-Seq, with 343 DEGs regulated in the 1 nm T3 group and 467 upregulated in the 10 nm T3 group. Several independent BP terms related to bone metabolism were significantly enriched, with a number of genes shared among them (FGFR2, WNT5A, WNT3, ROR2, VEGFA, FBLN1, S1PR1, PRKCZ, TGFB3, and OSR1 for 1nM T3; and FZD1, SMAD6, NOG, NEO1, and ENG for 10 nm T3). An osteoblast-related search in the literature regarding this set of genes suggests that both T3 doses are unfavorable for osteoblast development, mainly hindering BMP and canonical and non-canonical WNT signaling.Conclusions: Therefore, this study provides new directions toward the elucidation of the mechanisms of T3 action on osteoblast metabolism, with potential future implications for the treatment of endocrine-related bone pathologies.
