Published: August 2023

The quality of human resource performance was influenced by the welfare of human resources that can be provided as salaries/income to employees. Several theories are used to determine employee salaries or income, including pay for performance and position theory. In determining employee salaries, reasonable financial projections are needed in educational institutions. One projection method that can be used is the Capital Budgeting method, utilizing a profitability index model. The method used in this study is descriptive analytics by using a profitability index model to calculate projections and considering Pay for Performance and Pay for Position on pesantren expenditure items. The subject of this study was the management of Darullughah Wal Karomah Islamic Boarding School, namely the head, treasurer, head of staffing, and principal under the auspices of the pesantren with stages of data collection through interviews and document studies, implementation of analysis, and focus group discussion. Based on the calculation of pay for performance and pay for position and combined with the results of calculating the profitability index, it was found that the form of awards in the form of income that is suitable for use by pesantren is the use of pay for position theory for pesantren administrators and pay for performance for teachers and education staff. The results of this research can be used as a basis for Islamic boarding schools to compile guidelines for providing income to employees.

Authors:   Postgraduate Program of Biomedical Science, Sriwijaya University, South Sumatra, Indonesia, Susilawati Susilawati , Anwar Chairil , Saleh Irsan , Salni Salni
Published: August 2023

Vulvovaginal candidiasis is the second most common cause of vaginitis after bacterial vaginosis with at least 75 – 80% of women have had one episode of VVC in their lifetime. Their prevalent resistance to most commonly used antifungal agents makes their treatment a challenge to physicians. Flavonoids have been shown to possess potent anti-Candida properties which can inhibit the growth and proliferation of Candida species through various mechanisms, including inhibition of fungal cell wall synthesis, disruption of fungal cell membrane integrity, and interference with fungal cell signaling pathways. Their potency makes them potential candidates for the development of antifungal agents for the treatment of candidiasis, alone or in combination with existing antifungal drugs. The review aims to explore the mechanisms by which flavonoids inhibit the growth and proliferation of Candida species, including the inhibition of fungal cell wall synthesis, disruption of fungal cell membrane integrity, and interference with fungal cell signaling pathways.

Software System for Visualization and Checking the Consistency of Experts’ Evaluative Knowledge
Authors: Malaeva E. D. , Yakhyaeva G. E.
Published: August 2023

Expert evaluations are used everywhere and in solving a wide range of problems, but often there is a problem of inconsistency in the set of expert evaluations. In this paper, we propose an algorithm for checking the evaluative expert knowledge for consistency. As a result of the algorithm, we not only get an answer about whether the data is consistent or not, but also visualize the original data in the form of a tree. If the introduced expert evaluations are inconsistent, the constructed tree “highlights” the edges in which there is an inconsistency. The algorithm also offers two alternative ways of resolving evaluation inconsistencies. The article describes a software system developed on the basis of this algorithm.

Authors: Gavrishev A. A.
Published: August 2023

In this article, by the combined application of the programs E&F Chaos, Past, Fractan, Eviews Student Version Lite, mathematical, numerical and computer modeling of some of the well-known two-dimensional generators of chaotic signals based on modular arithmetic presented in [4] was carried out, and the properties of the obtained chaotic signals were evaluated using nonlinear dynamics methods (time and spectral diagrams, BDS-statistics, Hurst exponent). As a result of the conducted research, it was found that the time and spectral diagrams obtained for the studied two-dimensional generators of chaotic signal based on modular arithmetic have a complex noise-like appearance similar to white noise. The resulting range of BDS-statistics values corresponds to white noise at a certain interval, and persistent processes (black noise) at a certain interval. The resulting range of values of the Hurst exponent is also close to white noise. The results obtained show that two-dimensional generators of chaotic signals based on modular arithmetic can relate to white noise and have more pronounced chaotic properties than classical generators of chaotic signals, on the basis of which they are created. The results obtained complement and expand the knowledge about two-dimensional generators of chaotic signals based on modular arithmetic and open up broad prospects for their use in various practical applications.

EUROPEAN COURT OF HUMAN RIGHTS AND THE EUROPEAN GREEN DEAL
Authors: Bakota Boris
Published: August 2023

The European Green Deal aims to make Europe the first climate-neutral continent by 2050 and maps a new and inclusive growth strategy to boost the economy, improve people’s health and quality of life, care for nature, etc. EU Farm to Fork Strategy for fair, healthy and environmentally- friendly food system, among others, asks for „moving to a more plant-based diet“. Plant-based diet is a diet consisting mostly or entirely of plant-based foods. Plant-based diet does not exclude meat or dietary products totally, but the emphasis should be on plants. Vegetarianism is the practice of abstaining from the meat consumption. Vegetarians consume eggs dairy products and honey. Veganism is the practice of abstaining from the use of animal product in diet and an associated philosophy that rejects the commodity status of animals. Article 9 of European Convention for the Protection of Human Rights and Fundamental Freedoms and article 10 of the Charter of Fundamental Rights of the European Union almost use the same text enshrining Freedom of thought, conscience and religion. To ensure the observance and engagements in the Convention and the Protocols, Council of Europe set up European Court of Human Rights. All European Union Member States are parties to the European Convention for the Protection of Human Rights and Fundamental Freedoms. European Court of Human Rights had many cases dealing with above-mentioned article 9. This paper will focus on Court’s cases dealing with veganism, vegetarianism and plant-based diet. It will investigate obligations, which arise from European Convention for the Protection of Human Rights and Fundamental Freedoms to public administration institutions, namely hospitals, prisons, army, school and university canteens, etc. The paper will explore the practice of several European countries and Croatia. The results will show if veganism, vegetarianism and EU promoted plant-based diet are equally protected under European Convention or there are differences, and what differences if there are any.
INDIVIDUALS AND THEIR RIGHTS IN THE MIDDLE OF DIGITALIZATION AND TECHNOLOGICAL PROGRESS OF THE SOCIETY
Authors: Treščáková Diana
Published: August 2023

The digitalization of the society, which has been going on for many years is considered as a natural process. We are part of processes that change ourselves and based on that change the essence of the functioning of our society every day. Many times we don’t even think about the consequences of our activity in the online environment - how we declassify our working and private spheres. Many times we do not even ask what is the fate of our data that we provide on the Internet and what kind of interference in our privacy can cause e.g. simple chatting on a social network. Our simply behaviour can extend to the violation of the protection of our basic rights and freedoms. The more serious is the situation when the above happens without our cause and knowledge, when Big Tech entities whose task is to “monitor” us for various reasons and our data are then passed on to other entities for a commercial purposes. Precisely for the reasons mentioned, it is very important to have these spheres protected by legal acts, adopted in compliance with the principle of technological neutrality, which are completed by court jurisprudence and which can guarantee us the observance of our fundamental rights and freedoms. The task of this article will be to analyse the ongoing digitalization and related legislative activity aimed at protecting the basic rights and freedoms of the individual, especially the protection of personal data of individuals and their privacy in the online environment.

Published: August 2023

Understanding metal surface reconstruction during operation is of the uttermost importance in heterogeneous catalysis as it directly affects the available active sites. However, surface reconstruction is notoriously difficult to study because of the dynamic nature of the phenomena behind it. Here, we report on the mechanism and the intermediates, which drive the rearrangement of copper catalysts during the electrochemical CO2 reduction reaction. In-situ methods, including mass spectrometry and fluorescence spectroscopy, evidence a dissolution – redeposition process mediated by transient species containing copper in +1 oxidation state. Theory identifies copper-adsorbate complexes which form in solution under operating conditions. Copper carbonyls and oxalates emerge as the major reaction-specific species driving copper reconstruction. This work motivates future studies to specifically target these compounds to improve the catalyst operational stability in the electrochemical CO2 reduction reaction.
Antimicrobial Delivery Using Metallophore-responsive Dynamic Nanocarriers
Authors: Raviranga N.G. Hasitha , Ramstrom Olof
Published: August 2023

The increasing prevalence of multidrug-resistant (MDR) pathogens has promoted the development of innovative approaches, such as drug repurposing, synergy, and efficient delivery, in complement to traditional antibiotics. In this study, we present an approach based on biocompatible nanocarriers containing antimicrobial cations and known antibiotics. The matrices were prepared by coordinating Gaᴵᴵᴵ or Inᴵᴵᴵ to formulations of chitosan/tripolyphosphate or catechol-functionalized chitosan, with or without encapsulated antibiotics, yielding particles of 100–200 nm hydrodynamic diameters. MDR clinical isolates of P. aeruginosa were found to be effectively inhibited by the nanocarriers under nutrient-limiting conditions. Fractional inhibitory concentration (FIC) indices revealed that cation- and antibiotic-encapsulated nanomatrices were effective against both Gram-negative and Gram-positive pathogens. Metallophores, such as deferoxamine (DFO) were probed to facilitate the sequestration and transport of the antimicrobial cations Gaᴵᴵᴵ or Inᴵᴵᴵ. Although the antimicrobial activities were less significant with DFO, the eradication of biofilm-associated bacteria showed promising trends against P. aeruginosa and S. epidermidis. Interestingly, indium-containing compounds showed enhanced activity on biofilm formation and eradication, neutralizing P. aeruginosa under Fe-limiting conditions. In particular, Inᴵᴵᴵ-crosslinked catechol-modified chitosan matrices were able to inhibit pathogenic growth together with DFO. The nanocarriers showed low cytotoxicity towards A549 cells and improvable CC₅₀-values with NIH/3T3 cells.

Published: August 2023

In this article, a deep insight into emulsion radiartion-induced graft polymerization (RIGP) was obtained by computing explicit solvation free energies, conformational entropy, monomer radius and dipole moments with the state-of-the-art Conformer-Rotamer Ensemble Sampling Tool (CREST) package primalily at semiempirical GFN-xTB level. By leveraging the robustness of the CREST package, above parameters provided dynamic nature of methacrylate monoers with the consideration of realistic emulsion conditions. With the chemical and physical importance of the above results, CREST-determined explanatory variables sufficiently led to the building of the prediction models for the RIGP of methacrylate monomers. The machine learning model building resulted in effective reactivity predictions and unveiled important factors for the radiation-induced graft polymerization in a chemically interpretable fashion.
Ab initio investigation of excited state charge transfer pathways in differently capped bithiophene cages
Authors: Shaalan Ahmad , Szalay Péter G. , Tajti Attila
Published: August 2023

The electronic excitations of conformationally constrained bithiophene cage systems as previously investigated by Lewis et al. (J. Am. Chem. Soc. 143, 18548 (2021)) are revisited, employing the correlated ab initio Scaled Opposite-Spin Algebraic Diagrammatic Construction Second Order (SOS-ADC(2)) electronic structure method. Quantitative descriptors are determined to assess the extent of charge transfer between the bithiophene moieties and the capping domains, represented by either phenyl or triazine groups. The investigation substantiates intrinsic differences in the photochemical behavior of these two structural variants and reveals the presence of lower-energy bright excited states characterized by noteworthy charge transfer contributions in the triazine cage system. The manifestation of this charge transfer character is discernible even at the Franck-Condon point, persisting throughout the relaxation of the excited state. By examining isolated monomer building blocks, we confirm the existence of analogous charge transfer contributions in their excitations. Employing this methodological approach facilitates the prospective identification of potential wall/cap chromophore pairs, wherein charge transfer pathways can be accessed within the energetically favor- able regime.
Model of preventive replacements of complex systems elements depending on the operation time and the number of failures
Authors: Emelyanov V. E. , Matiuk S. P.
Published: August 2023

Modern conditions of economic activity of civil aviation operators make actual the problem of economically feasible measures for the organization of technical operation and maintenance of industry equipment, in particular, means of radio technical support for flights and aeronautical telecommunications. At the same time, it is obvious that these means need to be transferred to maintenance on a condition, which, in turn, causes the need to solve the problems related to determining the time for the preventive replacement of elements which diagnosable parameters can reach limit values. This paper presents an algorithm for estimating the optimal replacement of elements using the conditional probabilistic characteristic method for systems with a long period of operation and having a fixed number of failures. An assessment of the accuracy of determining the desired parameter is carried out, provided that its changes have deterministic and random components. The mathematical expectation and variance of the obtained estimate are found. Provided that the time of means operation between restorations (repairs) tends to decrease with an increase in the number of failures, the average number of final failures is obtained that satisfies the Volterra integral equation. To analyze the cost of restoration within the framework of the proposed model, an expression was found for the unit cost of work, depending on the accepted replacement rule and the duration of the expected cycles. Taking into account the mathematical expectation of the latter and associated costs, a two-dimensional optimal replacement rule is formed, and the expediency of using such a replacement period that minimizes the maximum average costs is shown. The obtained results are useful in organizing activities for preventive maintenance of radio technical support for flights and aeronautical telecommunications at various stages of their life cycle.

The issues of ensuring the reliability of the finite element models (FEM) of the fuselage in the hatch cutout zone are considered at the early aircraft design stages. The purpose and tasks of research are formulated. To assess the reliability of mathematical models, the objects with standards were selected. The methods of experimental research and measuring instruments are discussed. The results of a comparative analysis of the numerical experiment with analytical solutions and full-size experiments data are presented. For the validation of FEM structures, the checkable characteristics and types of their verification are determined. The results of this research contain a discussion of the impact of finite element mesh details on a stress concentration factor, an adequacy of modeling the stress and strain field in the vicinity of the cutout and taking into account a nonlinearity in strength calculations of structures with stress concentration. This paper focuses on the analysis of modeling a framed cylindrical shell with a large rectangular cutout, for which full-size tests were conducted by TSAGI researchers. Strains of strong frames, limiting the cutout in a cylindrical shell, shearing and equivalent stress in the skin, normal stresses in stringers at the intersection with the strong frame, displacements of strong frames cross-sections at test points are analyzed. Based on the results of this research, the recommendations for modeling thin-walled fuselage structures in the vicinity of a large cutout, ensuring the performance of calculations with engineering accuracy were formulated.

Authors: Bokov S. R. , Efimov V. V.
Published: August 2023

In this paper, the object of research is the icing of aircraft surfaces during flight in the atmosphere. On many light aircraft, as well as on unmanned aircraft weighing less than 30 kg, there are no on-board de-icing systems. Nevertheless, aviation events occur with these aircraft, which are a consequence of their icing. Therefore, determining the most dangerous flight modes of aircraft in icing conditions is an urgent task. In view of the high cost of conducting flight tests and the impossibility of covering all possible events due to their potential danger, the complexity of creating flight conditions for aircraft in icing conditions on the ground, the mathematical modeling method was used in this study. To solve this problem, the analysis of the airworthiness standards of civil light aircraft, transport category aircraft, rotorcraft of normal and transport category was carried out within the framework of the work, the influence of various parameters on the thickness of ice build-up was investigated using a computational experiment conducted on the software developed by the authors of the article. On the basis of the results of the computational experiment, the dependences of the ice thickness on various icing parameters were obtained, a method was developed for determining the combination of heights and flight speeds of an aircraft, at which ice of the greatest thickness is formed on the surface of aircraft, other things being equal. Possession of this information will allow the aircraft crew and air traffic control specialists to avoid the most dangerous flight modes in terms of icing.

Differentiated cell nuclei can be reprogrammed after nuclear transfer (NT) to oocytes and the produced NT embryos can give rise to cloned animals. However, development of NT embryos is often hampered by recurrent reprogramming failures, including the incomplete activation of developmental genes, yet specific genes responsible for the arrest of NT embryos are not well understood. Here, we searched for developmentally important genes among the reprogramming-resistant H3K9me3-repressed genes and identifiedAlyrefandGabpb1by siRNA screening. Gene knockout ofAlyrefandGabpb1by the CRISPR/Cas9 system resulted in early developmental arrest in mice.Alyrefwas needed for the proper formation of inner cell mass by regulatingNanog, whereasGabpb1deficiency led to apoptosis. The supplement ofAlyrefandGabpb1mRNA supported efficient preimplantation development of cloned embryos.AlyrefandGabpb1were silenced in NT embryos partially because of the repressed expression ofKlf16by H3K9me3. Thus, our study shows that the H3K9me3-repressed genes contain developmentally required genes, and the incomplete activation of such genes results in preimplantation arrest of cloned embryos.
ГРАМАТИКА НІМЕЦЬКОГО СЛОВОСПОЛУЧЕННЯ: ДОСВІД СТРУКТУРНО-СЕМАНТИЧНОГО МОДЕЛЮВАННЯ
Authors: Приходько А. М. , Лазебна Н. В.
Published: August 2023

Статтю присвячено вивченню структурно-семантичних особливостей феномену "словосполучення" в сучасній німецькій мові, для чого розглядається його номінативна природа. Наводиться й аналізується перелік підрядних і сурядних моделей словосполучення, кожен з яких становить собою закриту (під)систему. Підрядне словосполучення постає як патерн "опорне слово – зв'язок – залежне слово" і являє собою структурно-семантичне зчеплення двох і більше слів з різним синтаксичним (опорне слово vs залежне слово), але з однаковим морфологічним статусом (приналежність до автосемантичних частин мови). Низхідне моделювання підрядних ССп враховує параметри: частиномовна приналежність опорного слова (дієслово, субстантив, ад’єктив, адверб) і тип зв’язку (узгодження, керування, примикання), що у сукупності дає 11 моделей (із потенційних 24) і 21 субмодель у межах пропонованого теоретичного підходу. Сурядне словосполучення будується за алгоритмом «Слово А – зв'язок – слово В» і являє собою єдність двох і більше слів з однаковим граматичним статусом. Загальним принципом їх конструювання є монофункційність складників і однорідність своїх членів. Основними їх ознаками є тип зв’язку (відкритість vs закритість), кількість поєднуваних компонентів (бі- vs полікомпонентність) і частиномовна приналежність опорного слова, що дає також 10 моделей, але лише 18 субмоделей. З’ясовано, що при використанні моделей словосполучення спрацьовують механізми, які дають «дозвіл» на реалізацію одних і/або накладають «заборону» на реалізацію інших моделей при побудові реальних речень. Доводиться, що і словосполучення, і речення мають фрактальну природу, бо в основних свої рисах зводяться або до сурядно, або до підрядно структурованих конструкцій. При цьому речення, використовуючи «будівельний матеріал» словосполучення, повторює в основних своїх рисах його структурно-семантичний алгоритм, розгортаючись або за моделлю сурядності, або за моделлю підрядності, або ж за моделлю комбінованої гібридності (речення-період).
НЕСТАНДАРТНІ ПЕРФОРМАТИВНІ ВИСЛОВЛЮВАННЯ ЗАБОРОНИ ТА ЇХ СЕМАНТИЧНІ Й МОДАЛЬНІ ВІДПОВІДНИКИ

Published: August 2023

У цій науковій розвідці йде мова про мовленнєвий акт заборони та його реалізацію в мовленні. Було з’ясовано, що заборона – це самостійний семантичний тип спонукання, який реалізується в мовленнєвій діяльності різнорівневими мовленнєвими засобами, згрупованими на прагматичній основі з урахуванням функцій, які вони виконують. Було визначено, що до нестандартних перформативних висловлювань заборони належать конструкції п’яти семантичних груп. Було проаналізовано індикатори заборони двох груп: семантичні відповідники стандартних перформативів та модально-семантичні відповідники стандартних перформативів. До нестандартних перформативних уживань мовленнєвих актів заборони належать конструкції заборонено; забороняється; не дозволю (-имо); не дозволено; не дозволяється. Граматичну основу цих висловлювань становлять дієслова забороняти, не дозволяти в першій особі однини чи множини майбутнього часу або в безособовій формі на -ся, -но, які вживаються як заборона на прохання про дозвіл. До першої групи нестандартних перформативних висловлювань заборони належать семантичні відповідники стандартних перформативів, які є індикаторами «заборони-застереження», «заборони-вказівки» (короткі та стислі за змістом) і «заборони-інструкції» (місткі та поширені). Було визначено, що модально-семантичні відповідники в мовленнєвих актах заборони представлені двома групами: 1) неможливості; 2) неповинності. Заборона неможливості в усному та писемному мовленні репрезентовані словами категорії стану можна з часткою не в препозиції, сміти, треба з семантикою повинності в заперечній формі (з часткою не), які можуть уживатися для заборони думки, погляду чи дії, про яку говориться у висловлюванні-стимулі Причини та передумови тих або інших модальних відтінків у конструкціях заборони прочитуються та тлумачаться з контексту їх уживання.

Published: August 2023

The first tube communication system “Blokada-1”designed for The Naval Forces of Workers’ and Peasants’ Red Fleet (MS RKKF) was among the first domestic radio-electronic systems. The scientifically grounded concept for its construction and implementation was developed by the first chairman of the Communications Section of the MS RKKF Science and Technology Committee, a professor Imant Georgievich Freiman, a head (1917–1929) of the first national department of radio engineering in Electrotechnical Institute, who continued the work A. S. Popov in all scientific and social areas. Research and teaching activities of I. G. Freiman, including active experimental work, gives grounds for determining his role in the history of radio engineering and radio electronics as the founder of the scientific and engineering school of radio engineering in Russia.
