The article analyzes modern trends in the development of the agro-industrial complex. The peculi-arities of the capitalization of agro-industrial enterprises in the conditions of hostilities on the territory of the state are determined. The peculiarities of the functioning of the enterprises of the agro-industrial com-plex in the conditions of a difficult security situation are substantiated. The main priority tasks of managing the capitalization of agro-industrial enterprises have been formed, taking into account the prospects of the economic and security situation in the state. The main directions of ensuring the financial and economic security of the development of agro-industrial enterprises as part of the general food security of the state are proposed. The main directions of state support for agro-industrial enterprises capable of contributing to the development of the industry on the international market have been determined.It has been investigated that today the agro-industrial complex of Ukraine is in a state of crisis due to hostilities on the territory of the state, especially in border areas, territories of temporary occu-pation, where cultivated areas are damaged. It is noted that in order to maintain competitiveness and the possibility of entering global sales markets, it is advisable for domestic agricultural enterprises to create integrated associations, which will contribute to increasing the level of capitalization and faster adaptation to new conditions. It was analyzed that as a result of the expansion of the spheres of activity, there is a reduction of disproportions in the financial and economic sphere, which has a positive effect on the general state of the agricultural enterprise. It was determined that the main problem of all agri-cultural enterprises is the lack of a sufficient level of financial resources to expand their activities, to attract new innovative technologies that would allow not only to improve production processes, but also to ensure the ecological use of the land fund in the long term.

The development of any country’s economy is closely linked to the activities of enterprises, their ability to develop and compete in international and local markets. In 2015-2019, our country's economy experienced a periodof gradual recovery, with exports of services and products increasing annually. However, already in 2019, the COVID-19 pandemic began to spread, and appropriate quarantine measures were introduced, which led to a decline in the economy not only of our country. In the addition, starting from 24 February 2022, the Russian aggressor’s full-scale invasion of Ukraine was added to this, which caused significant disruptions in economic sphere as well. It is safe to say that the hostilities on the territory of out country have caused negative trends in production, consumption, demand and, what is more important, in logistics. In such circumstances, Ukraine's economy, in particular, needs to adapt to the conditions of war, to regenerate and recover in the post-war period. An ability to adapt quickly in unpredictable situations is an essential component of existing and functioning of any enterprise. It encourages business owners constantly research the market, analyze it and create new concepts to meet customer needs and save costs. The article defines the essence of the concepts of "logistics" and "supply chain", analyzes the state of logisticsactivities during the full-scale invasion of Ukraine by Russian troops. The main logistical problems faced by Ukrainian enterprisesduring martial law are highlighted. It is determined that the priorityfor Ukrainian exports is now security. The challenges faced by logistics professionals in the domestic and international markets are highlighted as well. It is found that today it is highly important for Ukraine to consolidate international partnerships in the field of logistics, as this is the only way to preserve its export potential.
SOCIAL RESPONSIBILITY OF THE ENTERPRISE IN THE CONTEXT OF ENVIRONMENTAL DEVELOPMENT

Published: March 2024

Growing attention to corporate social responsibility and calls for the implementation of social responsibility principles in high-tech industries prompt us to explore the relationship between corporate social responsibility and company performance. The purpose of the study is to analyze the institutional prerequisites at the international level in the field of corporate social responsibility in the context of environmental development of enterprises. In the business context, social responsibility is recognized by all stakeholders as a topical issue, and companies are beginningto focus their efforts on being recog-nized as socially responsible. Modern technological innovations and social organizations continue to impose risks and limitations on the effective functioning of the biosphere. Human activity leads to the fact that sustainable natural resources are becoming less and less durable, and multiplier effects go beyond the traditional benefits of economic production and consumption. The paper analyzes the EU experience in the field of spreading the concept of corporate social responsibility.Responsibility can be understood in different ways, but the most important concepts are causal, moral and legal responsibility. Moral and legal responsibility are forms of normative responsibility, i.e. there is a standard against which an actor is judged. Although they do not require causal responsibility, such normative judgements are often formed under the influence of causal relationships. A causal relationship exists between something that happens or exists and something that partially or wholly caused it. The cause does not nec-essarily have to be a person, it can be a natural phenomenon, for example. Even though a hurricane or tsunami may cause damage to people or property, they cannot be held morally responsible for this destruc-tion. It is generally accepted that moral responsibility implies moral activity. Only moral actors can, for example, be held responsible for the socio-political or economic factors behind poor local infrastructure that increases the number of casualties in a hurricane or tsunami

Authors:   Zaporizhzhia National University, Khrapkin Oleksandr
Published: March 2024

The article deals with the peculiarities of ensuring strategic management of information security of modern enterprises. Nowadays, information security systems are designed to ensure the full function-ing of an enterprise's information infrastructure using various types of information services, automation of financial and production activities, as well as its business processes.The basic provisions of information security are formalized and enshrined in the Information Security Strategy of Ukraine. Other regulatory documents and standards of enterprises must comply with the laws and regulatory framework of Ukraine, international law, industry standards and EU and NATO directives.The article considers the need to form an information security management system, which is caused by the existence of internal and external threats, their destructive consequences for the activities and image of an enterprise. The tasks of information security are analyzed: data confidentiality, integ-rity, availability, ensuring the reliability of information, ensuring the legal significance of information, ensuring the untraceability of user actions. Information security management involves identifying po-tential risks to an enterprise, assessing the potential impact, developing and implementing strategies to eliminate problems designed to minimize risks with the available resources.The main stages of developing an information security policy are identified: complete registration of all information resources that require protection; formation of a list of possible threats to each re-source from the list; assessment of the probability of occurrence of each threat; application of actions for the effective protection of each resource. The basic principles of an information security management system for an enterprise are outlined: ease of use, full control, open architecture, access limits, least privileges, sufficient stability, and minimization of duplication. It is also about storing and processing significant amounts of information of varying degrees of confidentiality, so the issue of protecting im-portant enterprise information data from various internal and external threats is relevant

The human amniotic membrane surrounds and protects the developing fetus and separate the mother and fetus. It has several properties that make it particularly suitable for wound healing. This dressing contains significant amounts of cytokines and growth factors essential for tissue repair. Traditionally, the amniotic membrane has been used for wounds healing in burn wounds and diabetic foot ulcers. The amniotic membrane may be effective for deep or incurable wounds [2]. Chemotherapy extravasation is an accidental leak of chemotherapy drug in the subcutaneous tissue around the intravenous line. There is no standard treatment for these wounds [3].

Gestational Diabetes Mellitus (GDM) and abnormal thyroid function are two common endocrine disorders occurring during pregnancy. In this study, we evaluated the correlation between the levels of different thyroid hormones and blood glucose control in pregnant women with diet-controlled GDM. Mid-pregnancy serum samples were obtained from 439 participants with GDM controlled by diet for analyses of thyroid function. A 2-h 75-g oral glucose tolerance test was used to evaluate the effect of blood glucose controlled by diet. According to blood glucose levels before and 2h after a meal, mothers were grouped into GDM-A1 (≤5.3mmol/L, ≤6.7mmol/L, respectively) and GDM-A2 (>5.3 mmol, >6.7mmol/L, respectively) and these groups were compared to the associated thyroid levels using multivariate logistic regression analysis. Our results show that fT3 was positively associated with GDM-A2. The adjusted odds ratio (95% confidence interval) comparing the highest and lowest fT3 quartile was 3.12 (1.66, 15.87) at the second trimester. Neither TSH nor fT4 was significantly associated with GDM-A2. Higher FT3 levels during the second trimester of pregnancy are a risk for GDM-A2 incidence. This provides new ideas for the control of GDM.

Published: March 2024

To achieve chemical accuracy in free energy calculations, it is necessary to accurately describe the system's potential energy surface and efficiently sample configurations from its Boltzmann distribution. While neural network potentials (NNPs) have shown significantly higher accuracy than classical molecular mechanics (MM) force fields, they have limited range of applicability and are significantly slower than MM potentials, often by orders of magnitude. To address this challenge, Rufa et al suggested a two-stage approach that uses a fast and established MM alchemical energy protocol, followed by reweighting the results using NNPs, known as endstate correction or indirect free energy calculation. In this study, we systematically investigate the accuracy, robustness, and efficiency of free energy calculations between a MM reference and a neural network target potential (ANI-2x) using free energy perturbation (FEP) and non-equilibrium (NEQ) switching simulation in vacuum. We investigate the influence of longer switching lengths and the impact of slow degrees of freedom on outliers in the work distribution. We compare the results to multistage equilibrium free energy calculations (MFES) for an established dataset. Our results demonstrate that free energy calculations between NNPs and MM potentials should not be performed using FEP but require NEQ switching simulations to obtain accurate free energy estimates. NEQ switching simulations between MM and NNPs are highly efficient, robust, and trivial to implement.

Published: March 2024

Catalysts are essential for sustainability because they decrease the energy and resource consumption in the production of high value-added products. The design of a novel catalyst is a challenging and expensive target, and a simplified methodology for catalyst development can trigger burgeoning progress in both academic and applied research. Here, we demonstrate a reaction network that autonomously yields the photoredoxcatalyst for transformation of the provided substrate under applied catalytic conditions. The system stems from the reversible condensation pathway leading to deazaoxaflavins, 2H-chromeno[2,3-d]pyrimidine synthetic analogs of flavins, with which they share photoorganocatalytic activity. We report on the photocatalytic activity of deazaoxaflavins and their covalently dynamic behavior. The reversibility principle allows for the exchange of one of the deazaoxaflavin constituents for a different moiety, thus leading to the adaptability of the catalyst. We argue that the observed phenomenon is of thermodynamic origin and thus can be applied to other photo/organocatalytic reactions, in which the combination of a suitable substrate and conditions are the governing principle for catalyst formation.

Published: March 2024

Many composites in nature are formed in the course of biomineralization. These biocomposites are often produced via an amorphous precursor such as amorphous calcium carbonate (ACC), demonstrating a layered structure. In the current study, we utilized robocasting, a 3D-printing technique, to print layered structures inspired by the mineralized tissues of Ophiomastix wendtii and Odontodactylus scyllarus, which exhibit a layered organization. We compared various bio-degradable organic matrices with a high percentage (>94%) of ACC reinforcements and studied their mechanical properties. With the organic matrix protection, ACC was stabilized for long periods, exceeding even two years, when stored at ambient conditions. The layered structures were printed and fractured using the three-point bending method to evaluate their strength. The fracture interface was examined to weigh the benefits an amorphous precursor may offer in the 3D printing processes of ceramic materials. The fracture interface presented bulk behavior with no distinct layering, resembling the formation of mineral single crystalline tissue in nature and overcoming one of the most critical challenges in 3D printing, namely the inter-layer interfaces. Herein, we present a bio-inspired, low-temperature route to form layered structures. By fusing the layers together following low-temperature sintering, a composite structure composed of stabilized ACC integrated with biodegradable environmentally friendly matrices, can be obtained.

Published: March 2024

Alcohols are selectively oxidized to their corresponding aldehydes catalytically via mechanochemistry using a gold-coated milling vessel. Superior catalytic efficiency and selectivity was achieved through the meticulous modulation of milling frequency, duration, and media, complemented by controlled heating. Achieving a turnover number (TON) near 8200 and a turnover frequency (TOF) of 0.77 s-1, the system notably surpasses existing alternatives. Utilizing atmospheric oxygen as the primary oxidant facilitated significant yields, with the highest reaching up to 99% for selected substrates. The catalytic reaction indeed occurring on the surface of the vibrating milling ball was confirmed via X-ray photoelectron spectroscopy (XPS). This study highlights the pivotal role of operational parameter optimization in enhancing catalysis, emphasizing the method's sustainability and broad applicability across various alcohol substrates. The findings contribute significantly to green chemistry, offering an efficient, sustainable approach to alcohol oxidation.

Published: March 2024

Bistable rotaxanes were used to develop pH-switchable systems for singlet dioxygen photoproduction. Based on the combination of a Zn(II)-tetraphenylporphyrin photosensitizer, which was attached to the macrocycle, and a black-hole-quencher, which was used as one of the rotaxane-stoppers, singlet oxygen production could be switched on/off ((Δ= 0.15/0.03) by the addition of base/acid. However, we found that only a sufficiently long linker between both stations on the thread enabled switchability, and that the direction of switching was inversed with regard to the original design. This unexpected behavior was attributed to intramolecular folding of the rotaxanes, as indicated by extensive theoretical calculations. This evidences the importance to take into account the conformational flexibility of large molecular structures when designing functional switchable systems.
Directional Bias in Molecular Photogearing Evidenced by LED-coupled Chiral Cryo-HPLC
Authors: Gnannt Frederik , Gerwien Aaron , Dube Henry
Published: March 2024

Molecular gearing systems are technomimetic nanoscale analogues to complex geared machinery in the macroscopic world and are likewise defined as systems incorporating intermeshed elements which perform correlated rotational motions by mechanical engagement. Only recently, new methods to actively drive molecular gearing motions instead of relying on passive thermal activation have been developed. Further progress in this endeavor will pave the way for unidirectional molecular gearing devices with a distinct type of molecular machine awaiting its realization. Within this work an essential step towards this goal is achieved by evidencing directional biases for the light-induced rotations in molecular photogear system 1. Using a custom-designed LED-coupled chiral cryo-HPLC setup for the in-situ irradiation of enantiomeric analytes, an intrinsic selectivity for clockwise or counterclockwise rotations was elucidated experimentally. Significant directional biases in the photogearing (PG) processes and light-induced single bond rotations (SBRs) are observed for photogear 1 with directional preferences of up to 4.8:1. Harnessing these effects will allow to rationally design and construct a fully directional molecular gearing motor in the future.

Time-resolved photoelectron spectroscopy using an extreme-ultraviolet (XUV) probe pulse was used to investigate the UV photoinduced dynamics of adenine (Ade), adenosine (Ado), and adenosine-5-monophosphate (AMP) in a liquid water jet. Unlike previous studies using UV probe pulses, the XUV pulse at 21.7 eV can photoionize all excited states of a molecule, allowing for full relaxation pathways to be addressed after excitation at 4.66 eV. This work was carried out using a gas-dynamic flat liquid jet, resulting in a considerably enhanced signal compared to a cylindrical jet. All three species decay on multiple time scales that are assigned based on their decay associated spectra; the fastest decay of ~100 fs is assigned to ππ* decay to the ground state, while a smaller channel with a lifetime of ~500 fs is attributed to the nπ* state. An additional slower channel in Ade is assigned to the 7H-Ade conformer, as seen previously. This work demonstrates the capability of XUV-TRPES to disentangle non-adiabatic dynamics in aqueous solution in a state-specific manner and represents the first identification of the nπ* state in the relaxation dynamics of adenine and its derivatives.

Upconversion (UC) of low-energy photons to higher-energy photons has enabled exciting advances in applications such as 3D printing, bioimaging, and more. In particular, UC of near infrared photons into visible photons has been identified as a process which can enhance photovoltaic, night vision, and anti-counterfeiting technologies. Triplet-triplet annihilation UC is particularly attractive for these applications due to its low upconversion thresholds and broadband, tunable absorption. However, current state-of-the-art near-infrared-to-visible triplet-triplet annihilation solid-state UC devices made of PbS quantum dots and rubrene are limited by (1) low absorption of near infrared photons, (2) low energy transfer rates, and (3) highly parasitic back transfer processes, leading to low external quantum efficiencies unsuitable for wide application. Here, we propose a device architecture that allows for strongly absorbing PbS films with improved efficiencies. We use 5-tetracene carboxylic acid as an interlayer to improve Dexter energy transfer to rubrene and alleviate parasitic back transfer leading to an improvement by a factor of 5 compared to control devices. Finally, we demonstrate that these devices allow for visible upconversion anti-counterfeiting with an incoherent light source at modest intensities, highlighting their potential for UC-facilitated technologies.
First Principles Study of Aluminum Doped Polycrystalline Silicon as a Potential Anode Candidate in Li-ion Batteries

Published: March 2024

Addressing sustainable energy storage remains crucial for transitioning to renewable sources. While Li-ion batteries have made significant contributions, enhancing their capacity through alternative materials remains a key challenge. Micro-crystalline silicon is a promising anode material due to its tenfold higher theoretical capacity compared to conventional graphite. However, its substantial volumetric expansion during cycling impedes practical application due to mechanical failure and rapid capacity fading. We propose a novel approach to mitigate this issue by incorporating trace amounts of aluminum into the micro-crystalline silicon electrode using ball milling. We employ density functional theory (DFT) to establish a theoretical framework elucidating how grain boundary sliding, a key mechanism involved in preventing mechanical failure, is facilitated by the presence of trace aluminum at grain boundaries. This, in turn, reduces stress accumulation within the material, reducing the likelihood of failure. To validate our theoretical predictions, we conducted capacity retention experiments on undoped and Al-doped micro-crystalline silicon samples. The results demonstrate significantly reduced capacity fading in the doped sample, corroborating the theoretical framework and showcasing the potential of aluminum doping for improved Li-ion battery performance.

Authors: Khan Jabir , Tyagi Aparna , hazra chinmoy Kumar
Published: March 2024

A metal-free strategy has been developed for the α-arylation of carboxylic acids, secondary amides, and esters employing arenes as key reagents. This process entails the Lewis-acid catalyzed reductive Friedel–Crafts alkylation of aromatic and heterocyclic arenes with α-ketoacids, facilitated by silane as a reductant in HFIP solvent. The transformation is highly efficient and mild, providing significant advantages over existing protocols. Notably, the method exhibits exceptional tolerance towards various functional groups, enabling late-stage functionalization of pharmaceutical compounds and natural products such as Thymol, and Sesamol. The reaction mechanism has been studied through control experiments, providing valuable insight. This one-step reductive Friedel–Crafts type protocol has been successfully used in the synthesis of various commercially available drugs, such as Adiphenine, Piperidolate, derivatives of Ketoprofen, Ibuprofen, and Flurbiprofen, and Bromopropylate pesticide. Furthermore, after the gram-scale synthesis, the solvent (HFIP) was recovered, demonstrating the method's suitability for industrial applications.

The electrochemical production of hydrogen peroxide (H2O2) via metal-free catalysts has garnered attention as a viable and sustainable alternative to the conventional anthraquinone process. The precise architectural design of these electrocatalysts poses a significant challenge, requiring intricate structural engineering to optimize the electron transfer during the oxygen reduction reaction (ORR). Herein, our study introduces a novel design of covalent organic frameworks (COFs) that effectively shift the ORR from a four-electron to a more advantageous two-electron pathway. Notably, the JUC-660 COF, with strategically charge-modified benzyl moieties, achieved a continuous high H2O2 yield of over 1200 mmol g-1 h-1 for an impressive more than 85 hours duration in a flow cell setting, marking it as one of the most efficient metal-free and non-pyrolyzed H2O2 electrocatalysts to be reported. Theoretical computations alongside in-situ infrared spectroscopy indicated that JUC-660 markedly diminishes the adsorption of the OOH* intermediate, thereby steering the ORR towards a desired pathway. Furthermore, the versatility of JUC-660 was showcased through its application in the electro-Fenton reaction, where it efficiently and rapidly removed aqueous contaminants. This work delineates a pioneering approach to altering the ORR pathway, ultimately paving the way for the development of highly effective metal-free H2O2 electrocatalysts.
Environmental Content as a Part of Science-Oriented Sustainable Development Goals in Grades 6 and 7 of Slovenian Primary School: An Analysis of Science Textbooks
Authors: Vošnjak Matej , Rebolj Neva , Devetak Iztok
Published: March 2024

Slovenian science education in Grades 6 and 7 (11- and 12-year-old students) of primary school focuses on the integration of various science subjects. According to the current Slovenian science curriculum, environmental concepts, as a part of science-oriented sustainable development goals, are an integral part of the subject of science. In 2026, a new science curriculum will be introduced in the education system to provide students and teachers with competences for sustainable development. Consequently, the aim of this study is 1) to analyse old (valid prior to the 2010/2011 school year) and current 6th and 7th-grade Slovenian science curriculum for primary school from an environmental and sustainability perspective, and 2) to investigate textual and pictorial material of four 6th grade and four 7th grade textbooks available for students in the current school year (2023/24) of primary school, that relate to environmental content, as well as their overall structure. The analysis of the textbooks showed that all textbooks explain some environmental topics recommended by the national curriculum. The text is supported by pictorial elements that present phenomena with realistic pictures on the macrolevel. The present study suggests that some environmental content is present in 6th- and 7th-grade science textbooks that are consistent with the learning goals of the curriculum but that a significant amount of sustainability content is missing. For this reason, the curriculum reform currently underway in Slovenia should more clearly include the implementation and thoroughly consider the integration of science-oriented sustainable development goals into the science curriculum in Grades 6 and 7.

Neural network approach to detect renal calculi
Authors: Reuben B. , Ambujam K.
Published: March 2024

Back Propagation Network is the most commonly used algorithm in training neural networks. It is employed in processing the images and data to implement an automated kidney stone classification. The conventional technique for classifying medical resonance kidney images and detecting stones relies on human examination. This method is not accurate since it is impractical to handle large amount of data. Magnetic Resonance (MR) Images may inherently possess noise caused by operator errors. This causes earnest inaccuracies in classification features and diseases in image processing. However, the usage of artificial intelligent based methods along with neural networks and feature extraction has shown great potential in extracting the region of interest using back propagation network algorithms in this field. In this work, the Back Propagation Network was applied for the objective of kidney stone detection. Decision-making is carried out in two stages, Feature extraction and Image classification. The feature extraction is done using the principal component analysis and the image classification is done using Back Propagation Network (BPN). This work presents a segmentation method using the Fuzzy C-Mean (FCM) clustering algorithm. The performance of the BPN classifier was estimated in terms of training execution and classification accuracy. The Back Propagation Network gives precise classification when compared to other methods based on neural networks.

Authors: Guo Mengdi
Published: March 2024

Objective: To investigate the efficacy of rituximab in the treatment of idiopathic membranous nephropathy with varying levels of serum phospholipase A2 receptor antibodies. Methods: A total of 137 patients with idiopathic membranous nephropathy admitted to Beijing Sixth Hospital were selected. Based on their blood PLA2R antibody levels before rituximab treatment, patients were categorized into the PLA2R antibody positive group (n = 94) and the PLA2R antibody negative group (n = 43). They were followed up for at least 1 year, during which the efficacy, measured through 24-hour urine protein quantification and serum albumin levels, were compared between the two groups before and after treatment. Results: After 3 months of treatment, there was no significant difference in the quantitative levels of 24-hour urine protein between the two groups (P > 0.05). However, after 6 and 12 months of treatment, there was a significant difference in the levels of 24-hour urine protein between the two groups (P < 0.05). Additionally, after 3 months of treatment, there was a notable difference in the serum albumin levels between the two groups (P < 0.05). However, after 6 and 12 months of treatment, there was no significant difference in serum albumin levels between the two groups (P > 0.05). Analysis of complications in the two groups revealed that in the positive group, 9 individuals experienced thrombosis, 5 had infections, and 11 developed acute kidney injury (AKI). In contrast, in the negative group, 5 individuals had thrombosis, 2 had infections, and 3 developed AKI. There was no statistically significant difference in complications between the two groups (P > 0.05). Conclusion: Serum anti-PLA2R antibody levels provide valuable insights into the clinical observation of rituximab treatment for idiopathic membranous nephropathy. They aid in understanding the disease’s pathogenesis, evaluating treatment efficacy, and predicting disease prognosis.

Objective: To explore the impact of a continuous precision nursing model on patients’ Knowledge, Attitudes, and Practices (KAP) and cardiac function during the nursing process of patients undergoing percutaneous coronary angiography and stent implantation. Methods: Ninety patients who underwent percutaneous coronary angiography and stent implantation in our hospital from April 2022 to April 2023 were selected and randomly divided into the control group (45 cases), in which routine nursing support was carried out during the treatment process, and the observation group (45 cases), in which continuous precision nursing model was carried out during the treatment process. Comparisons were made between the two groups of patients on their KAP, cardiac function, and quality of life during recovery. Results: There was no difference in the left ventricular ejection fraction (LVEF), cardiac output (CO), and cardiac index (CI) levels before intervention. After the intervention, the levels of cardiac function in the observation group were higher than those of the control group (P < 0.05). There was no difference in the Exercise of Self-Care Agency (ESCA) self-care ability scale scores before the intervention. After the intervention, the observation group had higher ESCA scores than the control group (P < 0.05). Conclusion: Implementation of a continuous precision nursing model in the care of patients undergoing percutaneous coronary angiography and stent implantation improved the patient’s cardiac function, and KAP, and promoted recovery.
