The aim – to identify patients with true resistant arterial hypertension and to assess patients’ adherence to treatment on the background of a fixed combination of antihypertensive drugs.Materials and methods. 1146 patients with resistant hypertension were included in the study. Men and women over the age of 18 were included, provided that the average level of office blood pressure (BP) was greater than 140/90 mm Hg, when taking 3 or more antihypertensive drugs. Morisky – Green Questionnaire (in a modified scale) (MMAS-8) on patient adherence to treatment. To determine adherence to treatment in some patients, determination of drugs in urine was carried out in the central laboratory. All patients were initially subjected to the following tests: measurement of office SBP, DBP and heart rate, daily monitoring of BP, biochemical blood test.Results and discussion. 51.4 % of patients took 3 antihypertensive drugs. 48.6 % took 4-6 antihypertensive drugs: among them, 4 drugs – 37.1 %, 9.1 % – took 5 drugs, and 2.4 % – 6 drugs. The degree of decrease in office BP among patients taking 3 or more antihypertensive drugs was 43.47 ± 0.65 mm Hg for systolic BP, and 20.33 ± 0.74 mm Hg for diastolic BP (p<0.001 for both values). 355 (31 %) patients failed to achieve the target level of office BP. They had true resistant hypertension. According to the Morisky – Green adherence questionnaire, on the background of the fixed triple combination of valsartan/amlodipine/hydrochlorothiazide, there was a significant improvement in adherence for all questions of the questionnaire. Patients began to forget to take pills significantly less, therapy became stable and regular, there were much fewer cases of stopping taking drugs due to deterioration of the patient’s condition after taking them, all 100 % of patients took antihypertensive drugs on the eve of the visit to the doctor, patients stopped canceling therapy due to their well-being at against the background of treatment, much fewer patients were bothered by the inconvenient regimen of taking drugs. Patient pill size was significant in only 11.4 % of patients at baseline and did not significantly change after 3 months of treatment with the fixed triple combination. But if patients had a choice, 60 % of them would choose the smaller pill. According to the determination of drugs in urine among 12 patients, we found that 25 % of patients (n=3) did not take drugs at all.Conclusions. Resistant arterial hypertension was found in 31 % of patients taking 3 or more antihypertensive drugs. When determining adherence to treatment based on the detection of drugs in urine, 25 % of patients with resistant arterial hypertension did not take the prescribed drugs at all, that is, they had pseudoresistance.

Although concrete is the most widely used building material in the world, its limited tensile strength makes cracking a common phenomenon in concrete elements. This study investigates the potential of autonomous self-healing as an eco-friendly and lowcost method to increase the durability of concrete. The crack-healing potential of different types of high-alkaline-tolerant bacteria or calcite-precipitation microorganisms is investigated. High-alkaline-tolerant bacteria and calcite-precipitation microorganisms were used to retrofit lab-fractured concrete samples. The samples healed with each of these bacteria groups were cast and tested under compressive load up to failure to measure the compressive strength of the concrete samples. The outcomes of experimental tests on concrete samples healed with biological processes demonstrate how this technique can be implemented when retrofitting durability-enhanced, eco-friendly concrete structures to improve the strength of durability of the material and ultimately improve the durability of many forms of concrete infrastructure.

Physical Meaning of Euclidean Approach to the Problems of Relativity
Authors: Nawrot Witold
Published: May 2023

INTRODUCTION: In this paper, we discuss the fundamental problem of the relationship between the true and observed shapes of reality.

OBJECTIIVES: Considered is the problem if, is the Minkowksi space-time the model of the “true” reality or is the Minkowski model of the reality a result of existence certain mysterious structure of the reality which is simpler than the Minkowski space-time but for some reason it is observed as the Minkowski space-time.

METHODS: As a solution to this problem, a novel approach is proposed, where the time and space dimensions are not the “true” dimensions creating reality, but are merely certain directions in a four-dimensional Euclidean reality, and these directions are not stable but depend on the observation of a pair – an observer and an observed body. In other words, an observer for observing various bodies needs to choose each time a different set of directions interpreted by him as the dimensions of time and space. According to the new model of reality, relativistic effects are the result of a change in the angle of mutual inclination between directions (in four-dimensional Euclidean reality) interpreted by an observer as the dimensions of space and time of his coordinate system in four-dimensional Euclidean reality, instead of deformation of dimensions of space time, as is currently assumed in the Minkowski model.

RESULTS: Such a model provides a much simpler description of reality at the cost of a more complicated manner of observation. It also allows the connection of the relative motion with the absolute space, allows the description of a particle directly as a wave in E4 (not as a mysterious wave function), and explains the Hubble law and Mach principle. Almost all the results of the new approach are identical to those obtained from the Minkowski model; however, a few of them allow us to draw conclusions different from those predicted by the Theory of Relativity, which can be a reliable test for the correctness of the new approach.

CONCLUSIONS: The new idea of reality deeply changes our understanding of reality not only in the range of the Theory of Relativity but also because of the description of particles directly as waves of E4 - also of Quantum Mechanics.

Published: May 2023

The article is dedicated to the study of separate and joint impact of the magnetic field and the addition of newly prepared composition on the rheological properties of high-paraffin emulsion oil. The new composition has been prepared in a 1:1 ratio of Difron-4201 to BAF-1 reagents under laboratory conditions. The sample taken from well number 208 of the SOCAR oil field has been used as high paraffin oil. Separate and joint impact of the magnetic field and composition on the freezing temperature, effective viscosity and amount of asphaltene-resin-paraffin deposits of high-paraffin oil has been studied. It has been determined that the joint impact of the magnetic field and the addition of composition on all three parameters is more effective that the use of a separate impact. Thus, the separate action of magnetic field and composition resulted in reducing the oil freezing temperature from +170С to +40C and +20C, respectively, while the freezing temperature of oil drops to –20C under the joint impact. The effective viscosity of oil under the impact of the magnetic field is 0.66 Pas; it is 0.44 Pas under the impact of the addition of composition; and it is equal to 0.003 Pas under the joint impact. The separate and combined impact of the magnetic field and the composition addition on the amount of paraffin deposits have been studied by "coldfinger test" method. It has been determined that the effect of the magnetic field on paraffin deposits accumulated on the surface of the coldfinger test is 52%, the effect of the composition addition is 74%, and the effect of the combined impact is 90%.

The adhesive properties of brand BND 60/90 road bitumen with the oxidized phosphatide concentrate additive were studied. It was shown that the oxidized phosphatide increases the adhesive properties of bitumen brand BND 60/90. Oxidized phosphatide concentrate can be recommended as cost-effective alternative to expensive synthetic cationic surfactants, which are now widely used as adhesives for road bitumen. Based on the results of laboratory tests, the mathematical analysis of the obtained data was performed. Comparative graphs were plotted, and Pearson's correlation coefficients and the approximation reliability values were calculated. It was found that the optimal composition for creating effective bituminous compositions with an increased thermo-physical and adhesive characteristics is 0.6 wt.% of oxidized phosphatide concentrate.

This study reports the features of the mass transfer kinetics during the extraction of phenolic compounds and flavonoids from the Carlina acaulis roots. The extraction process of target compounds was optimized and the mathematical model was selected, which implies that the mass transfer of target compounds occurs during the extraction of the solid phase (plant cells) into the liquid phase (extractant). The most effective hydrodynamic conditions for the production of phenolic compounds and flavonoids were determined. An experimental verification of the kinetic equation was carried out by extracting the target compounds from the studied object of various sizes in a vessel with a stirrer using 40% and 70% ethanol as an extractant. The results of the experiment indicated that the target compounds extraction process, namely phenolic compounds and flavonoids from the Carlina acaulis roots, proceeds more efficiently under stirring conditions when using particles with a diameter of 2 mm and 70% ethanol as an extractant. The experimental data are in good agreement with the theoretically calculated results, which confirms the appropriateness of using the selected mathematical model. Studies of the kinetics of Carlina acaulis roots extraction process will allow minimizing the losses of target compounds, and improving the extraction process and the quality of final product.

New substituted pyridines were synthesized by the reaction of spiroimidazolidinones with the Vilsmeier-Haack reagent (PBr3/DMF) with satisfactory yields. The reaction proceeds as an electrophilic trigger process according to the push-pull mechanism due to the anomeric effect of two nitrogen atoms with an increase in the primary heterocycle. An explanation is proposed for the different chemical behavior of 5',6',7',8'-tetrahydro-1'H-spiro[cyclohexane-1,2'-quinazolin]-4'(3'H)-one and spiroimidazolidinones under Vilsmeier-Haack reaction conditions. The likely reason is the hybridization of the amine (enamine) nitrogen atom in the structure of heterocycles. The reaction of spiroimidazolidinones with the Vilsmeier-Haack reagent results in formylation of the ammine nitrogen atom with subsequent reaction steps; and in the case of 5',6',7',8'-tetrahydro-1'H-spiro[cyclohexane-1,2'-quinazolin]-4'(3'H)-one, the reaction results in formylation of carbon atom followed by heterocycle opening and its intramolecular cyclization. The synthesized new pyridine derivatives, due to the presence of several reaction centers in them, are of interest not only as potential pharmacologically active compounds, but also as low-molecular building blocks for organic synthesis.

Authors: Лозинський М.В. , Устинова Г.Л. , Ображій С.В.
Published: May 2023

In 2017‒2019, 42 F1 and F2 populations of bread winter wheat obtained from hybridization of varieties that differ in vegetation period were studied in the experimental field of the research and production center of Bila Tserkva National Agrarian University. The aim of the study was to determine the heterosis and the degree of phenotypic dominance in F1 and transgressive variability in F2 by the number of spikelets in the main ear, when using in hybridization of different bread winter wheat varieties.

It was found that during the years of research, in the parental forms the number of spikelets in the main ear was 15.7‒18.0, and their formation was significantly influenced by genotype, year conditions and their interaction. The majority of F1 by the number of spikelets in the ear exceeded the original forms, with high rates (21.0‒19.2) in Chorniava / Stolychna, Bilotserkivska napivkarlykova / Chorniava, Chorniava / Vidrada, Kolchuga / Stolychna. In 39 from the 42 hybrids, the inheritance of the spikelets number from the main ear occurred by positive dominance. High hypothetical (Ht = 23.5‒15.4 %) and true (Hbt = 18.6‒10.2 %) heterosis was found in F1 Chorniava / Stolychna, Kolchuga / Stolychna, Bilotserkivska napivkarlykova / Chorniava, Chorniava / Vidrada, Zolotokolosa / Vidrada.

In 85.7 % of F2 populations, a positive degree of transgressions with the maximum manifestation of the spikelets number in the main ear (20‒24) was determined in recombinants, which indicates a significant shaping process and the possibility of selection on the basis of the studied trait. The maximum number of spikelets in the main ear (22‒24) was formed by the majority of populations in which the varieties Myronivska Rannia, Kolchuga, Zolotokolosa, Chorniava and Antonivka were used as maternal forms. The frequency of transgressive recombinants in these populations was 3.3‒96.7 %.

Published: May 2023

Wheat (Triticum aestivum L.) is one of the major grain crops in the world. Wheat powdery mildew is a fungal disease caused by the infection of Blumeria graminis F. sp. tritici. It is one of the most severe wheat diseases globally, seriously affecting the yield and quality of wheat. At present, the main ways to control powdery mildew are the use of fungicides and the cultivation of disease-resistant varieties. The extensive spraying of fungicides causes pesticide residues and environmental pollution. At present, no matter wild type or artificially bred wheat powdery mildew resistant varieties are scarce, so it is urgent to cultivate resistant varieties quickly and efficiently. Traditional cross breeding has a long time and low efficiency. Still, it is a fast and effective way to get disease-resistant sorts by using modern molecular biological means to transfer disease-resistant genes into cultivated varieties. Although the cultivation of resistant varieties is the most economical and effective way to control powdery mildew in wheat, there are some limitations in the cultivation of resistant varieties by introducing resistance genes by conventional means in actual production. With the increase of disease each year, this situation will be more and more unable to meet the needs of wheat genetic improvement. It is urgent to explore a new way of breeding to improve the wheat to powdery mildew lasting broad-spectrum resistance. The disease-resistant breeding needs from cloning in plant and pathogen affinity interactions play a vital role in the study of disease genes and their mechanism of action. At present, in the wheat by manipulating disease genes make infected material gain lasting broad-spectrum resistance is less. In the case of disease genes and mutations after its disease-resistant mechanism are still not clear. So the breeding of resistant varieties need mining and utilization of resistance genes. The paper summarizes the harm and distribution of wheat powdery mildew, the genes resistance mechanism of wheat powdery mildew, and functional analysis, wheat powdery mildew resistance genes in the field of molecular biology research status, and VIGS, RNAi, such as for the prevention and control of wheat powdery mildew, explore new powdery mildew resistance genes and resistance regulation, breeding disease-resistant varieties of wheat provide the feasible scheme.

The world around us is changing. The workforce is changing rapidly. The pandemic and the war have drastically shortened the business path to remote and hybrid work models. The advent of technology and data makes personnel management easy and more complex at one time. Business processes of personnel management are undergoing significant changes under the influence of digitalization. For this transformation to be manageable and meet organizational needs, digital HR strategy formation is necessary. Theoretical understanding and modernization of context defining the new challenges of the digital HR transformation, its stages, components and elements, and the development of a digital HR strategy for the transformation of personnel management are necessary. The article is devoted to the study of the paradigm of digital HR strategy forming, namely: concepts, components, principles, and stages of its forming in organizations. The relationship between the concepts of digital HR transformation and digital HR strategy is substantiated. Vectors and stages of digital HR transformation are highlighted. The components of the digital HR transformation are summarized and characterized, and the components of the digital HR strategy are selected based on them. The introduction of new HR technologies must be supported by a digital HR strategy, which is a detailed plan for the digital transformation of personnel management. To sustain the digital transformation of HR management, companies need a clear digital HR strategy that will involve a strategic rethinking of the use of digital HR technologies to increase business value; rules for forming and implementing a digital HR strategy. The software has enormous potential, but it is important to approach the choice strategically. Any investment in new technology should be tied to specific company goals and have a detailed deployment plan. Modern business tasks cannot be solved using outdated solutions, so traditional sets of HR competencies will not be sufficient; they need to be updated to include new means of communication and critical analysis. In addition, HR teams cannot and should not allow others to make important technological decisions for them, impose on them solutions that are not designed specifically to solve the problems of personnel management of a specific business environment; and, instead, take the initiative to develop and implement a digital HR strategy.

The pulp and paper industry produces the remaining bark as solid waste, where this solid waste pile when it rains will produce leachate that seeps into the ground, causing soil and groundwater pollution. This wood waste can be used as activated carbon (adsorbent) for leachate treatment. The research was divided into two stages, namely adsorbent production and leachate treatment. Production of activated carbon from bark (bark) was activated using a solution of NaOH and H2SO4 as an activator, with variations of bark (gr): activator (ml) = 20:100; 50:200; 70:300. The leachate adsorption process used activated carbon with a mass of 2.5 and 5 g for 30, 60 and 120 minutes. The lowest adsorbent water content was 0.87% activated using NaOH, and the lowest ash content 0.79% when activated with H2SO4. This is still in accordance with the SII standard No.0258-88. The best variation occurred when the addition of activated carbon which was activated using 5 grams of H2SO4 for 120 minutes caused the most significant decrease in COD value of 52%, and pH 7.32. From the variations in the activation of activated carbon adsorbents, the activation of acidic solutions is better in leachate treatment.

Authors: Zin Myroslav , Koval Vadym , Tarasenko Mykola , Sysak Ivan
Published: May 2023

The paper is devoted to further development of small hydropower on the basis of reliable and cheap unregulated tubular propeller hydroturbines with rigidly fixed operating and guide blades. Such turbines are used mainly at low-pressure small hydroelectric power stations. Their main drawback is the impossibility of generated power regulation. However, solutions that minimize this shortcoming are proposed in this paper. Matrix of 4 model series of tubular propeller hydroturbines has been created. The nomenclature of turbines presented in this matrix is aimed at improving technical characteristics of small hydropower plants and reducing their negative impact on the environment. The rules for equipping machine platforms of low-pressure small hydroelectric power plants with capacity up to 200 kW with models of turbines from the created matrix are proposed, and their technical and environmental justification is performed. According to the recommendations given in the paper, at least two different adjacent turbines from the same model line should be installed at one HPP. The best option is three different adjacent turbines from the same model series, but technical and economic analysis should be performed for more detailed justification of the choice of the number of turbines. This is the subject of our further investigations. The application of scientific and practical results presented in the paper will improve technical characteristics of small hydropower plants with tubular propeller turbines and minimize their possible negative impact on the life of river flora and fauna in lower basin.
The methodical peculiarities of the investigation of portal crane rolled steels degradation
Authors: Nesterov Oleksandr
Published: May 2023

Rolled structural steels of port structures, operating under intensive cyclic loading, are particularly susceptible to the degradation of their mechanical properties. Advantages of the investigation of operational degradation of steels based not on fatigue strength characteristics, but on characteristics of resistance to brittle fracture using the example of determining the impact strength of longitudinal and transverse Charpy samples in relation to the rolling direction of sheet metal for 10 local areas at different structural nodes of portal crane are analyzed. This is caused to a great extend by micro-layering along the stretched fibers in the rolling direction of the rolled product. Accordingly, the mechanical properties of the metal become particularly sensitive to the direction of samples cutting in relation to the direction of rolling. Therefore, in order to evaluate the steel operational degradation it is recommended to use transverse samples in which the direction of micro-laayering coincides with the direction of rolling. Possible role of the marine environment in enhancing the degradation of steel due to its flooding properties is also considered in this paper.

Published: May 2023

Recently, e-education around the world is developing rapidly and the main problem is the timely provision of students with quality educational information. A significant impetus for this is the global epidemic of covid-19. The problem of implementing e-education cannot be solved without analysing the large flow of information coming into the information environment of e-education from participants in the educational process – students, teachers, administration, etc. In this environment, there are a large number of different types of data, both structured and unstructured, which are difficult to process by traditional statistical methods. The aim of the study is to show that the development and implementation of successful e-learning systems requires the use of new technologies that would allow the storage and processing of large data streams. Large amounts of disk space are required to store large data. It is shown that to solve this problem it is expedient to use cluster technology NAS (Network Area Storage), which allows to store information of educational institutions on NAS - servers and to have access to them from the Internet. To process and personalize Big Data in the e-learning environment, it is proposed to use technologies MapReduce, Hadoop, NoSQL and others. The article provides examples of the use of these technologies in the cloud environment. These technologies in e-learning make it possible to achieve flexibility, scalability, accessibility, security, confidentiality and ease of use of educational information. Another important problem of e-learning is the discovery of new, sometimes hidden, relationships in big data, new knowledge (data mining), which can be used to improve the educational process and increase the efficiency of its management. To classify electronic educational resources, identify patterns (patterns) of students with similar psychological, behavioural and intellectual characteristics, the development of individualized curricula in the article it is proposed to use methods of big data analysis. The article shows that to date, many software applications have been developed for big data mining. These software products can be used for classification, clustering, regression and network analysis of educational information. The application of these methods in e-education will allow teachers to receive timely information about students, to respond quickly to any changes in the learning process, to make timely changes to educational content. The obtained results of the research are offered to be used for development of recommendations at creation of electronic courses in higher and secondary educational institutions of Ukraine.

Background: Only a few studies investigated the association of a positive blood culture with mortality in the pediatric population, the predictive significance of a positive blood culture in children admitted to the Pediatric Intensive Care Unit (PICU) remains uncertain. This study aimed at evaluating the characteristics and outcomes of negative blood culture compared to those of positive blood culture in children admitted to the PICU of Chittagong Medical College Hospital (CMCH).
Materials and methods: A retrospective cohort study was conducted at the PICU of CMCH. All pediatric patients, from 1 month to 12 years of age, admitted between October 2021 and March 2022were included in the study. All blood culture samples sent from patients hospitalized in the PICU of CMCH between October 2021 and March 2022, were evaluated retrospectively. Information collected includes the demographic data, Primary diagnosis, and outcome of the patients.
Results: Of the 214 patients, 29 (13.6%) had a positive blood culture whereas 185 (86.4%) had a negative bacterial blood culture. Pneumonia was extremely common, present in 65.5% and 34% of the patients, respectively in culture positive and negative patients, and tended to result in a positive culture (p<0.001). Mortality was more in negative blood culture (11.9%) versus 6.9% in positive blood culture (p = 0.428). Culture-negative patients have a shorter median PICU stay (10 days) than culture-positive patients (15 days) (p<0.001).
Conclusion:The negative bacterial blood culture constitutes a substantial proportion of pediatric patients admitted to PICU. However, culture results were not associated with PICU mortality.

Europeanisation and Its Impact on Candidate Countries for EU Membership: A View from Ukraine
Authors: Lomaka Victoria , Yakoviyk Ivan , Bilousov Yevhen
Published: May 2023

Background: The nature of the European Union (EU) as a global actor has long been the subject of diverse academic debates. Proponents of an understanding of the EU as a normative force believe that its greatest transformative power lies not in coercion but in a policy of enlargement that allows the EU to stimulate reforms in the candidate countries of the Central and Eastern European region, despite the crisis of enlargement. The aim of the article is to study the impact of the Europeanisation process on the legal systems of member states and candidate countries, in particular Ukraine, as well as the formulation of proposals for national institutions regarding the perception of the ‘Europeanisation’ impact of EU law on the legal system of Ukraine.

Methods: The methodological basis of the work is interdisciplinary and comprehensive approaches. The interdisciplinary approach is based on the application of theoretical developments in jurisprudence, philosophy, political science, and the theory of international relations, which make it possible to study the process of Europeanisation in relation to member states and candidate countries as fully and comprehensively as possible. The comprehensive approach is aimed at identifying the multifaceted and multifactorial ontological determinants of the Europeanisation process of legal systems. These approaches determined the choice of appropriate general theoretical and special scientific methods: hermeneutic, dialectical, analysis, synthesis, etc.

Results and Conclusions: As a result of the study of the political will, capacity, and legitimacy of the EU to defend the values proclaimed in the founding treaties, in cases of violations of the regulations of the EU law by the member states, the authors come to the conclusion that the EU may face negative consequences due to the display of democratic reformist coalitions in individual member states (Poland and Hungary ), as well as due to favouring (authoritarian) stability over uncertain (democratic) change. Concession to candidate countries for EU accession in terms of the fulfilment of the Copenhagen criteria in exchange for satisfying the interests of leading member states may undermine the credibility of the project of building a European identity based on the common values of the EU, as well as the loss of the reputation of the normative power of the European Union. Accelerating the process of Ukraine’s accession to the EU, which is connected with Ukraine’s acquisition of the status of a candidate for accession to the EU, requires the Europeanisation of the domestic legal culture as a prerequisite for the modernisation of all other elements of the legal system. This, in turn, implies the completion of the process of de-Russification of legal science and education, the development and approval of the Legal Education Development Program, and the modernisation of legal terminology.

Features of Ensuring the Right to Liberty and Personal Integrity In Criminal Proceedings Under the Conditions of Martial Law: Precedent Practice of the European Court of Human Rights and Ukrainian Realities
Authors: Tumanyants Anush
Published: May 2023

This article is devoted to the study of problems related to the peculiarities of ensuring the right to freedom and personal integrity in criminal proceedings under martial law. It is noted that one of the principles of the state policy of Ukraine in the spheres of national security and defence is the protection of people and citizens, their life and dignity, and their constitutional rights and freedoms. The article analyses the conditions of admissibility of derogation, i.e., Ukraine’s right to derogate from the observance of individual rights, guaranteed, first of all, by Art. 5 of the European Convention on the Protection of Human Rights and Fundamental Freedoms (ECHR). The authors determine the constitutionality of legislative innovations caused by unprovoked Russian aggression and, as a result, the introduction of martial law in our country. The position is argued that the limitation of the right to freedom and personal integrity provided for by the Criminal Procedure Code of Ukraine (Parts 6-7 of Art. 176) only by the use of detention pursues a legitimate goal, which is to prevent persons who are reasonably suspected of committing a number of crimes from hiding from the investigation and the court, as well as perform any actions provided for in Part 1 of Art. 177 of the CPC of Ukraine, which, taking into account the difficult situation in the country associated with military aggression, can be considered fully justified. At the same time, in the future, at the stage of extending the term of detention, the suspect or the accused is actually deprived of the right to request his release from custody and the application of an alternative preventive measure to him, which does not correlate with international standards of limiting the right to freedom and personal integrity and does not comply with the legal positions of the European Court of Human Rights. The authors emphasise that the quasi-automatic extension of the term of detention of a person in custody without appropriate requests from the prosecution, without checking the presence of new or previous risks and assessing the expediency of further deprivation of liberty, introduced into the national legislation, should be considered as a violation of the conventional norms-guarantees established by § 3 Art. 5 of the ECHR.
