Authors: Savastieieva O. M.
Published: March 2023

The article examines the practical aspects of the implementation of measures aimed at improving and increasing the level of sustainability of economic development due to the special role of international financial and credit institutions in economic relations between individual states. It was found that international financial organizations act as a key mechanism for regulating the international monetary and financial system, as well as the main source of providing financial, technical and analytical assistance to countries on the way to socio-economic transformations. The special role of Ukraine's financial relations with the International Monetary Fund (IMF) against the background of the need to resist full-scale armed aggression was determined, and a retrospective analysis of the fund's program implementation since 1994 was conducted. The organization of IMF financing through the distribution of SDRs between countries and lending at interest rates, the rates of which are determined by the average rates in effect for loan funds in the world's leading currencies, and loans through the Resilience and Sustainability Trust (RST) credit trust were studied. The decisive role of lending by international institutions in the growth of the constantly growing foreign debt of countries has been clarified. The dynamics of the specific weight of countries that in modern conditions are experiencing a critical situation related to indebtedness, or have a high risk of the appearance of the specified situation, have been analyzed. It is substantiated that receiving credit tranches from the IMF has both positive and negative consequences of a long-term nature, and their main aspects are highlighted. The vectors for the further development of Ukraine's financial relations with the IMF have been determined in order to create a foundation for the recovery of the country's economy after the end of the war, the completion of already started reforms and the introduction of new reforms in the economic, financial, and social sectors, raising the standard of living of citizens, strengthening the exchange rate of the national currency in relation to foreign currency etc.

Determination of the Dependence of the Spectrophotometer Zero Line Speed Deviation on the Elution Parameters Alteration
Authors: Stankevich S.V. , Lysenko N.K.
Published: March 2023

To identify dependence of the drift rate on the elution parameters alteration (in high-performance liquid chromatography), four samples of chromatograms registered by the Milichrome A-02 liquid microcolumn chromatograph were formed and compared in pairs. This chromatograph was equipped with a two-beam spectrophotometric detector with the following operating spectrum, nm: 210; 220; 230; 240; 250; 260; 280; 300. To determine dependence of the drift rate on the elution parameters, comparison was made of the two samples average drift rates, which differed only in the parameter value under study. Hypothesis about the eluate temperature alteration effect on the drift rate was confirmed at the highest level of confidence. It was established that the drift rate increased in the most (by 26.54 times) precisely with an increase in the temperature by 10 °С. Twofold increase in the eluate rate led to an increase in the average drift rate over the spectrum by 81.65 %, and the twofold increase in the detector measurement interval --- by 33.82 % (despite this, hypothesis of this relationship was taken as false). Along with the temperature, activity of the eluate particles was increasing, and the amount of energy required for the electron transition to the higher energy levels decreased. The problem of drift readings is universal and relevant for many measurement instruments. Drift is caused by systematic alteration in the metrological characteristics of the measurement tool. As a result of the detector electromagnetic radiation energy absorption by particles dissolved in the eluate, such metrological characteristic of the spectrophotometric detector as the radiation intensity changes; and it changes randomly, which in 87.5 % of cases leads to a positive drift, and in 12.5 % --- to the negative drift

Published: March 2023

The purpose of this work lies in computational study of the floating potential distribution in the perturbed zone adjacent to the wall in the ionized flow of low-temperature plasma. As a result of electrophysical interaction, primary and secondary emission currents appear on the wall surface. Based on the probe theory, mathematical model was developed to determine the current values of the combustion products ionized flow and spatial potential on the surface of walls in the power plant flow path. Parametric calculation of the potential on the wall at its contact with the low-temperature plasma was carried out without and taking into account the secondary emission processes. The results obtained taking into account only the primary currents demonstrate alteration in the potential on the wall in the range of --(1.5--0.5) V at the plasma flow temperature of 1,000--3,500 K. Results are presented of the design research of the wall floating potential dependence with various secondary electron emission coefficients in comparison with the known experimental results. Metal walls were characterized by formation of a shielding layer, where only the primary currents appeared. It is shown that their floating potential changes the sign in dielectric walls, as coefficient of the secondary electron emission decreases. Parametric calculation of the current value near the wall was carried out showing that with an increase in pressure by 0.1--10 MPa, the current value was changing in the range of 0.005--0.025 A

Published: March 2023

The article highlights the results of the conducted research on forecasting the level of sustainable development in the European context. Based on the analysis of the scientific achievements of domestic and foreign scientists, it was determined that the existing methodologies had several problems associated with using a large number of indicators, which made it impossible to estimate a new object or period quickly. While considering this fact, the research aimed at constructing a model for calculating the level of sustainable development based on a limited set of open data, which would significantly facilitate the process of its assessment and forecasting. The basis of the research is data from the World Data Center for Geoinformatics and Sustainable Development and the “Sustainable development index” project. Modeling and analysis were carried out in MS Excel and RStudio applications. The obtained results demonstrate that it is possible to predict the level of sustainable development based on the approximation model using a limited set of territorial development indicators, which will lead to the loss of a minimal amount of information.

conclusions. The blends of ultrahigh molecular weight polyethylene/polypropylene (UHMWPE/PP) possess excellent processability, but limited by its reduced mechnical properties. Herein, the high mechanical properties and wear—resistance UHMWPE/PP composites were fabricated by the addition of silicon carbide (SiC) nanoparticles under a consecutive elongational flow without any other additives or solvents. The morphology and thermal properties, mechanical properties, wear resistance as well as scratch resistance of UHMWPE/PP/SiC composites were investigated . The mechanical properties and friction resistance of composites increase initially then decrease with the increase content of SiC. The optimum mechanical properties of UHMWPE/PP/SiC composites are achieved when the content of SiC is 3 phr. In addition, both the hardness and scratch resistance of composites improved upon increasing the content of SiC. These improved mechanical properties and wear resistance originate from the well disperison of SiC nanoparticles along with favourable interfacial adhesive under a consecutive elongational flow.

Published: March 2023

CC chemokine receptor 6 (CCR6) is one of the members of G protein-coupled receptor (GPCR) family that is upregulated in many immune-related cells, including B lymphocytes, effector and memory T cells, regulatory T cells, and immature dendritic cells. Coordination between CCR6 and its ligand CC motif chemokine ligand 20 (CCL20) is deeply involved in the pathogenesis of various diseases, such as cancer, autoimmune diseases, and psoriasis. Therefore, CCR6 is an attractive target for therapy and is being investigated as a diagnostic marker for patients. In a previous study, we developed an anti-mouse CCR6 (mCCR6) monoclonal antibody (mAb), C6Mab-13 (rat IgG1, kappa), applicable for flow cytometry by immunizing a rat with N-terminal peptide of mCCR6. This study investigated the binding epitope of C6Mab-13 using enzyme-linked immunosorbent assay (ELISA) and surface plasmon resonance (SPR) methods with the synthesized point mutated-peptides within 1-20 amino acids region of mCCR6. In ELISA, C6Mab-13 lost the reaction to the alanine-substituted peptide of D11A. The epitope of C6Mab-13 was identified to be Asp11 in ELISA. Furthermore, in SPR analysis, the dissociation constants (KD) could not be calculated for G9A and D11A mutants due to lack of binding. The SPR analysis demonstrated that the C6Mab-13 epitope comprises Gly9 and Asp11. Taken together, the key binding epitope of C6Mab-13 was determined to be around Asp11 on mCCR6. Based on the epitope information, C6Mab-13 could be useful for further functional analysis of mCCR6 in future studies.

The main purpose of this study was to determine the effect of variations in gamma ray dose on the physical and mechanical properties of natural fiber reinforced polymer blend composites. The method used in this research is experimental. This research was conducted on polymer blend composites, namely recycled High Density Polyethylene (rHDPE) and recycled Polypropylene (rPP) with bamboo fiber reinforcement with variations in gamma ray doses of 0 kGy, 25 kGy, 50 kGy, and 75 kGy. Bamboo is processed using a crusher into fibers with a size of 40 mesh and treated with 5% NaOH alkali for 10 minutes then dried using oven for 24 hour at a temperature of 105 °C to remove lignin contained in bamboo fibers. The composite was made using two machines, namely an extrusion machine with a heater temperature of 175 °C, 180 ºC, 185 ºC, and 190 ºC with a screw speed of 25 rpm. Then the injection molding machine with a temperature of 220 ºC with a specimen mold temperature of 90 ºC and an injection pressure of about 45 bar for 20 minutes. Gamma ray treatment was carried out after making the specimen before testing. Where a gamma cell irradiator is used and as a source of gamma rays, cobalt-60 (Co-60) is used. Tensile and water absorption tests are used to determine the physical and mechanical properties of the composite material according to ASTM D638 type V and ASTM D570-98 standards. The test results showed that the higher the dose used, the lower the physical and mechanical properties of the composite. The highest tensile strength was found at the 25 kGy dose treatment of 13.68 MPa and the lowest at the 75 kGy dose treatment.

In the current era, automatic motorbikes are the most popular motorbikes and are most widely used for everyday purposes. The motorcycle population always increases by around 5 million units every year. Of this amount, around 70% are motorbikes of the matic type, aka scooters. One trick that is usually used by automatic motorbike lovers to upgrade the characteristics of their automatic motorbike is to replace a part called the CVT roller. The aims of this study were: (1) To find out the effect on fuel consumption produced by a 110cc automatic motorcycle using variations in roller weight. (2) Knowing the effect on fuel consumption produced by 110cc automatic motorbikes using variations of engine speed. (3) Knowing the effect of using roller weight variations at RPM variations on fuel consumption on 110cc automatic motorcycles. The research method used is experimental. The research data was obtained by measuring the Honda BeAT New 2018 motorcycle sample. The independent variable is roller weight Variation and Variation of engine rotation. The dependent variable is fuel consumption. The data obtained were then analyzed using quantitative descriptive techniques by describing them in the form of graphs and tables. The results of this study are: (1) The use of variations roller weight 10, 12, and 14 grams have an effect on fuel consumption. The use of a roller that is heavier or lighter than standard (12 grams) has the effect of producing a more different fuel consumption. (2) Variations in engine speed (3500, 5000 and 6500 RPM) have an influence on fuel consumption. Each increase in engine speed, the fuel consumption will also increase. This happens because the higher the engine speed, the higher the amount of fuel burned in the combustion chamber. (3) Has the effect of fuel consumption on the use of roller weight variations and variations of engine speed. This effect lies in the average fuel consumption using less standard rollers when compared to using lighter or heavier rollers. Overall, if you take the best, then the right choice is a standard 12 grams roller, because it has the lowest average fuel consumption value.

Enchantment of performance spoofing attacks in sushisen algorithm wireless networks
Authors: P Senthil , M SUGANYA , Inakshi SS
Published: March 2023

Underwater wireless sensor networks (WSN) can be used for a variety of applications. High propagation delay, limited bandwidth, 3D deployment, and lack of power are some of the challenges faced UWSN. An adversary with low communication depth prevents nearby relay nodes from perforating the path. In this paper, proposed dropped packet ratio (DPR) can effectively prevent depth spoofing attacks by ensuring that an ineligible node is likely to be triggered and removed. After the new node is again sent delivery speeds is increase sensitive to power decrease under conventional conditions. Compared with the related protocol, the proposed new sushisen protocol achieves higher energy, capacity, and scalability.

In this work, an efficient renewable carbon catalyst obtained by sulfonation of bio-oil was used for the first time to produce terpene acetals by condensation of β-citronellal with alkyl alcohols (methyl, ethyl, propyl, butyl, isopropyl) at room temperature. The catalyst was obtained by a simple bio-oil reaction with sulfuric acid at 393 K for different times (15, 30, 60, 90, 120, and 240 min). Potentiometric titrations and FT-IR analyses showed the formation of very strong acid sites, likely -SO3H, with surface concentrations reaching 0.35 and 0.50 mmol/ gcatal, for the catalyst obtained with reactions 120 and 240 min. These catalysts were used in the β-citronellal condensation with alkyl alcohols to acetals with conversion and selectivity higher than 0 %, at room temperature using 3.96 wt.% catalyst, and 2 h reaction. The effects of temperature, time, different alcohols, and catalyst load were evaluated. The catalyst can be recovered and reused four times without significant activity loss.
