Published: February 2025

Optimal design of a structure is currently one of the most relevant sections in structural and applied mechanics. The theory of mathematical programming and the emergence of computers had a great influence on the optimal design of structures in the late 40s. This greatly expanded the range of structures and physical models that became available for optimal design.
The use of analytical optimization methods leads to success only when considering the simplest structures. Therefore, numerical methods for finding optimal parameters, which are PC-oriented, have become widespread in optimal design.
Designing is the most critical stage of creating a structure, during which technical characteristics are determined and the feasibility of the goal is checked. An integrated approach is required to take into account all requirements, and this is the main difficulty of optimal design. The process of creating an optimal structure is highly dependent on the optimization method, which plays a key role in the design of structures for various purposes.
This scientific article considers an integrated approach to the optimal design of the forced frequencies of a shell of a minimal surface with a square plan consisting of two straight lines and two semicircles under thermal and power loading. The numerical study of the optimization calculation was carried out as follows: the objective function is the weight of the minimum surface shell, the design variables are the thickness of the minimum surface shell from 1 mm to 100 mm, and the constraint is represented as the first forced vibration frequency of 0.2 Hz.
Based on the results of the numerical study, the weight of the minimum surface shell decreased by 11.2%, the first forced vibration frequency is 0.2 Hz, which meets the specified constraint.  We can draw a general conclusion that the author's methodology and the use of his own software make it possible to perform an effective optimization calculation for shells of minimal surfaces, and the use of two types of optimization types on one research object is an important applied problem for civil and applied mechanics
MULTI-CRITERIA PARAMETRIC OPTIMIZATION OF THE DISPLACEMENT AND WEIGHT OF THE SHELL OF THE MINIMUM SURFACE ON A TRAPEZOIDAL CONTOUR UNDER THERMAL AND POWER LOADING
Authors: Kosheviy Aleksandr
Published: February 2025

The application of optimal design to shells of minimal surfaces is a modern development in structural and applied mechanics. For such objects of study, two types of optimization calculations are used at once: optimization of the shape of the shells of minimal surfaces and parametric optimization of thickness. This formulation of the problem makes it possible to cover a large number of factors that affect the result - the creation of an optimal design.
The economic component of any construction project is one of the key ones in Ukraine. Designing a construction project is a key stage for creating an environment of economic feasibility and achieving the goal of profit. A separate stage in the design of a construction project is the calculation of the structure in two groups of limit states, which is where optimal design is applied.
The current state of global construction practice shows that the use of shells of various types and purposes, combining lightness with high strength and stability, is the most efficient and cost-effective. These properties are mainly possessed by shell systems, which are nowadays increasingly used in the construction of civil buildings and engineering structures for various purposes, as well as in the reconstruction of industrial facilities.
However, shell structures are not perfect either, and they have some drawbacks. Shell structures have increased deformability under concentrated and non-symmetric loads. In this regard, much attention is paid to stabilizing the shape of shells. The methods used to reduce the deformability of shell structures depend largely on their functional purpose. Stabilization of coatings of buildings and structures is generally achieved by restressing the stiffeners, while increasing the stiffness of the structure as a whole.
The developed methodology shows quite good results that coincide with the works of other authors and makes it possible to use two types of optimization for one research object simultaneously. The first stage is shape optimization, and the second stage is multicriteria parametric optimization.
This methodology makes it possible to perform optimization processes in an automated mode, which is an important applied task for construction and applied mechanics.
THEORETICAL STUDIES ON IMPROVEMENT OF THE COMBINED SOYBEAN SEEDER-CULTIVATOR
Authors: Vanin Volodymyr , Volokha Mykola , Lazarchuk Margarita , Baskova Halyna , Mihlevskaya Natali
Published: February 2025

Soybeans are one of the most widespread leguminous crops and are currently grown in more than sixty countries, including due to their environmental plasticity. The increase in soybean production, in particular in our country, is mainly due to the expansion of sown areas by reducing the sowing of cereal grains and some energy-intensive industrial crops. In the Forest-Steppe zone of Ukraine, the profitability of soybean cultivation is consistently positive (up to 90-120%), which makes it possible to produce it efficiently both for domestic needs and for export.
Soybeans are usually sown in a row method (up to 90% of the area) with SZ-3.6 grain seeders. Based on the analysis of existing technologies and means of mechanization of grain sowing, it was found that they do not fully meet the agrotechnical requirements for soybean sowing and need to be improved. The main task of agrotechnical measures during sowing is to create an optimal nutrition area by uniform depth of seeding in the soil and placement on the field area and to provide conditions for fast and strong seed germination, which is crucial for good plant development, growth and, ultimately, yield. In addition to heat, soil moisture is a limiting factor in obtaining simultaneous, friendly soybean germination. Rolling is used to "pull" moisture from the depths to the soil surface during seed sowing, although this technique is a subject of debate among researchers and farmers, as it can result in a significant increase in the hardness of the surface soil layer, especially after heavy rains and subsequent sharp warming.
It has been established that the working body that allows for better soybean sowing is a disk coulter on a parallelogram suspension with packer rollers installed before and after it. The article contains theoretical studies on the redistribution of loads under such a force scheme and their impact on the quality indicators of the sowing process, which can be an integral part of the mathematical apparatus for the automated design of tillage and sowing tools.
Almost all geometric parameters of the seeder-cultivator affect the redistribution of reactions in the links of the section.
The force on the coulter does not depend on the sowing depth, but on the weight of the sowing section and the traction force.
The closer the coulter attachment point is to the packer wheel, the greater the value of the pressing force, and thus the greater the depth of pressing. With a significant displacement of the coulter attachment point, the rolling force changes slightly, which can be considered positive for this design of the seeder, since in case of adverse effects on the cultivator-sower, it will be more stable and retain its technological parameters.
The analysis of the change in the load on the coulter with packer wheels can be recommended when using this type of seeder for sowing other crops.

Authors: Sharma Deepak , Orilade Afelemo , Sharma Priyanka , Zahid Fahad , Farrington Dean
Published: February 2025

BACKGROUND: Continuous renal replacement therapy (CRRT) requires effective anticoagulation to prevent circuit clotting. This study compared heparin and regional citrate anticoagulation (RCA) in an Intensive Care Unit (ICU), focusing on patient safety, cost-effectiveness, and nursing perspectives.

METHODS: This retrospective observational study included ICU patients undergoing CRRT with heparin (December 2021 - March 2022) and RCA (June 2022 - September 2022). Outcomes assessed were CRRT duration per patient, filter set cost, lifespan, and blood transfusion requirements. Data were extracted from electronic health records and analyzed using IBM SPSS Statistics Version 29.

RESULTS: RCA significantly increased CRRT duration per patient (198 vs. 101 hours, p = 0.037) and filter lifespan (67 vs. 24 hours, p < 0.001) compared to heparin. Filter cost per renal day decreased from £98.05 with heparin to £57.48 with RCA (p = 0.04). Blood transfusion requirements reduced from 0.59 to 0.27 transfusions per renal day, lowering daily transfusion costs from £84.96 to £39.58 with RCA.

CONCLUSION: RCA demonstrated clinical and economic benefits in CRRT compared to heparin, including improved filter longevity, reduced transfusion requirements, and overall cost savings.

CLINICAL SIGNIFICANCE: Implementation of RCA in CRRT can enhance treatment efficacy, reduce nursing interventions, and improve resource utilization in ICU settings.
Maritime Transport Between Conflict and Cooperation: The Implications of Logistic Rerouting in the Mediterranean Basin - The Case of the Port of Trieste
Authors: Borruso Giuseppe
Published: February 2025

The contribution focuses on the complex dynamics of maritime transport in the Mediterranean basin, with particular attention to local and regional implications arising from global crisis contexts. In particular, it will focus on the impact of geopolitical tensions in the Middle East and the resulting bottlenecks on logistics chains, such as the Houthi conflict and the blockade of the Bab el-Mandeb chokepoint, on the strategic choices of ship owners and the reconfiguration of maritime routes.

The events of the last few years have highlighted the fragility of globalised logistics chains and the strategic importance of certain chokepoints. Tensions in the Middle East have triggered a series of chain reactions in the maritime sector, with some shipowners opting for alternative solutions, such as circumnavigating Africa, to avoid the risks associated with transit through the Bab el-Mandeb Strait. However, other actors have continued to use traditional routes, carefully weighing the costs and benefits of each option.

The analysis will focus on the case of the Port of Trieste, a strategic logistics node in the Mediterranean, to understand how the new dynamics of maritime transport are affecting port activities and trade relations with countries in the basin. The opportunities and challenges for the port of Trieste in this context will be examined, with particular reference to the potential effects of reshoring and nearshoring on the region's production and logistics activities1.

Through a multi-scalar approach, which integrates elements of geopolitics, maritime economics and logistics, the study aims to provide an original contribution to the understanding of the transformations taking place in the maritime transport sector and their implications for local and regional economies, including the Weberian logic of localisation, in the light of the transformations taking place in the circular economy. In particular, an attempt will be made to answer the following questions:

– How have the geopolitical crises in the Middle East influenced the strategic choices of shipowners operating in the Mediterranean?
– What are the main consequences of the reconfiguration of maritime routes for ports in the Mediterranean basin, and for the Port of Trieste in particular?
– What are the opportunities and challenges related to reshoring and nearshoring for local and regional economies?
– What are the policies and interventions that can be adopted at local, national and international level to strengthen the resilience of logistics chains and promote the sustainable development of maritime transport?
Conclusions Not Yet Drawn from the Unsolved 4/3-Problem: How to Get a Stable Classical Electron
Authors: Faber Manfried
Published: February 2025

It has been known for over 100 years that there is a discrepancy between Maxwell’s electrodynamics and the idea of a classical electron as the “atom” of electricity. This incompatibility is known under the terms 4/3 problem of the classical electron and radiation reaction force and was circumvented in the currently most successful theories, the quantum field theories, by limit value considerations, by the mutual subtraction of infinities, i.e. by purely mathematical methods that eliminate obvious contradictions but are not really based on an intuitive understanding of its physical causes. The actual origin of the problems mentioned lies in the instability of the classical electron. Stabilization cannot be achieved within the framework of Maxwell’s electrodynamics. This raises the question of what a minimal change to the fundamentals of electrodynamics should look like, which contains Maxwell’s theory as a limiting case. A detailed analysis of the 4/3 problem points to models that fulfill these requirements.
Efficient Weather and Air Quality Forecasts Through AI
Authors: Xing Jia , Fu Joshua S.
Published: February 2025

Accurate and timely weather forecasts and air quality predictions are essential for designing effective strategies to manage weather-related events and air pollution. These forecasts also play a key role in understanding aerosol-meteorology interactions within weather systems. However, traditional numerical methods, such as chemical transport models (CTMs), are computationally intensive, and their high resource demands limit their practical use in real-time air quality management and weather forecasting. In response to these challenges, we develop a novel approach called DeepCTM4D, which leverages deep learning to replicate CTM simulations, enhancing the computational efficiency of meteorology and air quality modeling in the four-dimensional chemistry space. The DeepCTM4D model is trained to accurately predict atmospheric chemical concentrations based on inputs such as precursor emissions, meteorological factors, and initial conditions. The key advantage of DeepCTM4D lies in its ability to efficiently identify the main drivers of pollution formation and assess how changes in emissions and meteorological conditions influence air quality. The relationships between emissions, meteorology, and concentration that DeepCTM4D captures align with established atmospheric chemistry mechanisms, further supporting the model’s scientific validity. Overall, DeepCTM4D offers a promising solution for simulating complex atmospheric processes, providing policymakers with critical information needed to design effective pollution control strategies and weather-caused events. This AI-driven model can also be integrated into global weather and air quality forecasting systems, serving as a powerful tool for more efficient, real-time predictions.

Published: February 2025

Online shopping generally presents the pain point of not being able to try on products. Therefore, various industries are gradually developing and applying augmented reality (AR) to improve the online product experience. The purpose of this study is to explore the impact of AR in assisting the online presentation of cosmetics on consumers and, based on the S-O-R model, to examine how AR features affect consumers’ perceived value. In this study, AR features are categorized into interactivity, vividness, system quality, and product informativeness. Consumers’ perceived value after using AR makeup tools is divided into three dimensions: perceived emotional value, perceived cognitive value, and perceived social value. The study also examines how these perceived values influence consumers’ attitudes toward AR technology, which, in turn, affect their willingness to use AR makeup tools. Perceived social benefits and intention to use determine whether they will patronize brand websites. A research model was tested through an empirical survey of 81 valid participants. The PLS analysis results show that consumers’ perceived cognitive value is significantly affected by the interactivity, vividness, system quality, and product informativeness provided by AR. Perceived social value is significantly influenced by AR’s presence effect, while perceived emotional value is influenced by AR’s interactivity and vividness. The study also suggests that consumers’ perceived value affects their attitude toward AR technology, which, in turn, significantly influences their willingness to use AR makeup tools and patronize brand websites. The findings of this study provide the cosmetics industry with optimization suggestions for the application of AR makeup tools and contribute to research on AR technology.

Research on the Effective Scope of Low-permeability Hard Coalbed Coupling and Enhanced Permeability Technology
Authors: Ding Yuandong
Published: February 2025

Due to poor gas permeability, high gas content, and hard coal quality at the JiuLiShan coal mine, gas extraction is difficult, and hydraulic perforation has limited effect. This study proposes a permeability enhancement method combining loosening blasting and hydraulic perforation to improve coal seam gas permeability and extraction efficiency. Field tests confirm the technology's effectiveness, showing that the combined method significantly enhances the coal body's permeability. The effective influence radius of the 1# test group (small explosives) is 4-6m, while the 2# test group (large explosives) extends this range to 6-8m, leading to a sustained increase in gas extraction. This approach offers an effective solution for enhancing permeability in complex coal mine conditions.

Published: February 2025

In order to reduce the overall vulcanization cost of the viscoelastic shock absorber and prevent the premature cracking of its adhesive layer, the viscoelastic shock absorber was improved and designed. A new type of viscoelastic assembled shock absorber suitable for cold adhesive bonding was made by adding grooves to the steel plate and increasing the lateral pressure with bolts. Then, the mechanical properties of the new assembled shock absorber were tested under different working conditions to study its energy dissipation characteristics and failure mode. The storage modulus and loss factor of the viscoelastic damping material were calculated through the force- displacement hysteresis curve, and the influence of the device structure, lateral pressure, loading frequency and displacement amplitude on the mechanical properties of the shock absorber were obtained. The test results show that adding grooves to the steel plate and increasing the lateral pressure of the shock absorber can improve the ability of the shock absorber to dissipate vibration energy. Moreover, the greater the displacement amplitude and loading frequency, the more energy dissipated. Therefore, by adopting appropriate external conditions and reasonable internal structure, the energy dissipation performance of the damping material can be fully utilized and the shock absorption effect of the shock absorber can be greatly improved.

The analysis revealed a vast body of scientific literature demonstrating the high toxicity levels of mycotoxins commonly found in food raw materials and products. Mycotoxins such as aflatoxins, deoxynivalenol, zearalenone, ochratoxins, fumonisins, nivalenol, enniatin, T-2, HT-2 and patulin can cause chronic or acute toxicity in animals and humans, including hepatotoxicity, nephrotoxicity, carcinogenicity, neurotoxicity, immunotoxicity, teratogenicity and mutagenicity. The search for effective and scalable methods of decontaminating food systems from mycotoxins has primarily focused on non-thermal methods, with cold plasma treatment recognized as the most promising. A significant number of studies have shown that cold plasma can destroy up to 100% of mycotoxins in contaminated food systems.

Relevance. The article is devoted to the study and optimization of the dessert recipe based on goat’s milk curd paste with the addition of talkan. Talkan (ground grits) is added (10–20%) to increase the content of fiber and trace elements and improve taste and texture. Based on a balanced amino acid composition of cottage cheese paste with the addition of talkan, a functional product (dessert) with increased nutritional value and unique taste qualities has been created. Modern processing methods make it possible to preserve the beneficial properties of goat’s milk and create products with high nutritional value. Prebiotics, probiotics and other functional ingredients contribute to gut health and overall health improvement. The study includes increasing the nutritional value of cottage cheese paste with the addition of whey protein (5–10%) and inulin (1–5%) to improve its amino acid profile and obtaining a dessert with the addition of talkan (layers).Methods. To optimize the formulation, methods of improving the composition, optimizing quality, technology and safety were used. The analysis of the nutritional value, amino acid composition and organoleptic properties of the dessert was carried out on the basis of standard methods of analysis of milk and dairy products.Results. Pasteurization and fermentation parameters have been optimized, whey protein and inulin have been added. Regression analysis made it possible to predict the level of product quality. The addition of 5% whey protein and3% inulin during pasteurization at 85 °C for 5 minutes and fermentation at 42 °C for 6 hours provides an optimal balance between protein, amino acid composition and prebiotic activity.

Relevance. The digital transformation of economic processes determines a new format for interaction between subjects of the agro-industrial complex during the implementation of production and sales cycles. Acting as an intersectoral complex, the agro-industrial complex includes many interconnected and interacting elements of the system, the task of which is to ensure the country’s food security. Under the conditions of technological and natural-climatic prerequisites that influence the traditional format of activity of agricultural enterprises, as well as a set of factors that form barriers to stable development, the implementation of the fundamental task of the agro-industrial complex is possible by increasing the efficiency of interaction of its structural components. One of the ways to increase the efficiency of the agro-industrial complex in the context of digital transformation is the creation of a unified digital ecosystem, which implies a tool for coordinating and integrating participants, goods, AgTech solutions and scientific research results in a single information environment.Methods. During the study, the theoretical aspects of the digital transformation of the agro-industrial complex were studied, the current level of digitalization of the Russian agro-industrial complex was determined, the problem field and possibilities for implementing the digital ecosystem in the agroindustrial complex were identified through the use of systemic, structural-functional and statistical analyses, modeling methods, classification and deduction.Results. As a result of the research, a concept of the digital ecosystem of the Russian agro-industrial complex was created, considering the current state of the agricultural sector and market challenges. The proposed digital ecosystem of the agro-industrial complex is designed to increase the efficiency of agricultural enterprises, ensure the rational use of natural resources, and minimize the impact of barriers to the development of the agro-industrial complex through effective communication and coordination of key market participants in a unified information environment.
