MULTIMODAL LOGISTICS IN THE CONDITIONS OF A TURBULENT BUSINESS ENVIRONMENT TRANSPORT & LOGISTICS SYSTEM

The transport industry of Ukraine is an important component of the complex of infrastructural industries and a necessary material factor for ensuring production and logistics. The importance and relevance of the development of transport logistics is also due to its special importance in ensuring the security of Ukraine, especially in conditions of military influence. That is, transport multimodal logistics indirectly affects all components of national security - foreign economic, domestic political, economic, food, environmental, anti-terrorist, informational, scientific and technical, and others. The economic role of transport consists, first of all, in the fact that it is an organic link of every production, carries out continuous and mass delivery of all types of raw materials, fuel and products from points of production to points of consumption, and also ensures the division of labor, specialization and cooperation of production. The purpose of the research is the analysis of the development of the multimodal transport logistics system of the surrounding business environment under the influence of the turbulence of the martial law and in the post-war period. One of the key advantages of multimodal logistics is the ability to use different types of transport depending on the specific stages of the route and infrastructure capabilities. This avoids delays and reduces the risk of loss of time and money. In addition, multimodal logistics allows the use of cargo tracking technologies, which facilitates control over their movement and ensures accurate delivery times. This is important for a business that seeks to provide quality service to its customers. Despite the fact that logistics services are usually complex and expensive, some Ukrainian companies offer them absolutely free of charge. Now Ukraine needs to overcome difficulties and look for new ways. Ensuring security has become the main priority for Ukrainian commodity exports. Summing up, multimodal transport logistics is a strategic approach to optimizing transport flows, which allows to ensure the efficiency and competitiveness of logistics processes in the modern world. Thus, logistics is actively studying the situation and cooperating with government authorities to find bypass logistics routes around dangerous zones and war-torn trade bridges.

Optimization and Removal of Heavy Metals from Groundwater Using Moringa Extracts and Coconut Shell Carbon Powder


 
 
 
 Abstract: This study focuses on enhancing the efficacy and elimination of heavy metals from groundwater by employing bio-absorbents generated from Moringa extracts and Coconut shell carbon powder. The green synthesis technique was utilized to produce cost-effective absorbents, including powdered Moringa seeds, leaves and carbon from coconut shells. The study examines the effectiveness of synthetic bio-absorbents in removing heavy metals, including Copper (Cu), Cadmium (Cd), Iron (Fe), Lead (Pb), Chromium (Cr), and Zinc (Zn), from groundwater. Identifying functional groups such as Hydroxyl (OH), C-H of alkenes, C=C of alkenes, and C-O from carboxylic acids have been determined to be essential for removing metals in groundwater. The method of FT-IR spectroscopy was used to characterize these functional groups. The examination of the morphology of Moringa seeds indicated the presence of consistent spherical network sheets, but Moringa leaves had a hexagonal network structure like a flower. The coconut shell photos revealed the presence of irregular, small-sized flakes that were clustered together to create a sheet. In light of the escalating deterioration of groundwater quality in Vijayawada as a result of industrial expansion, urban development, and significant infrastructure initiatives, the primary objective of the study was to ascertain the primary contaminants present in the groundwater. Subsequently, adsorption methods utilizing natural bio-absorbents were employed. Water samples were gathered and exposed to bio-absorption utilizing powdered Moringa olifera leaves, powdered Moringa olifera seeds, and powdered carbon derived from coconut shells. The technique of Atomic Absorption Spectroscopy was utilized to examine the decrease in concentrations of heavy metals. The findings demonstrated that the bio-absorption of heavy metals was more prominent in Moringa olifera seed powder than in Moringa olifera leaf powder and coconut shell carbon powder. The highest levels of adsorption for copper, cadmium, and lead were achieved at 98.5%, 99.5% and 99.4%, respectively. This work offers useful insights into the potential of bio-absorbents manufactured using green methods for effectively eliminating heavy metals from groundwater. It addresses the crucial problem of water quality in metropolitan areas.
 
 
 

Cascade Exotherms for Rapidly Producing Hybrid Nonisocyanate Polyurethane Foams from Room Temperature Formulations.

For decades, self-blown polyurethane foams─found in an impressive range of materials─are produced by the toxic isocyanate chemistry and are difficult to recycle. Producing them in existing production plants by a rapid isocyanate-free self-blowing process from room temperature (RT) formulations is a long-lasting challenge. The recent water-induced self-blowing of nonisocyanate polyurethane (NIPU) formulations composed of a CO2-based tricyclic carbonate, diamine, water, and a catalyst successfully addressed the isocyanate issue, however failed to provide foams at RT. Herein, we elaborate a practical solution to empower the NIPU foam formation in record timeframes from RT formulations. We generate cascade exotherms by the addition of a highly reactive triamine and an epoxide to the formulation of the water-induced self-foaming process. These exotherms, combined to a fast cross-linking imparted by the triamine and epoxide, rapidly raise the temperature to the foaming threshold and deliver hybrid NIPU foams in 5 min with KOH as a catalyst. Careful selection of the monomers enables producing foams with a wide range of properties, as well as with an unprecedented high biobased content up to 90 wt %. Moreover, foams can be upcycled into polymer films by hot pressing, offering them a facile reuse scenario. This robust cheap process opens huge perspectives for greener foams of high biobased contents, expectedly responding to the sustainability demands of the foam sector. It is potentially compatible to the retrofitting of industrial foaming infrastructures, which is of paramount importance to accommodate existing foam production plants and address the huge foam market demands.

The article deals with the chronology of wartime events in 1941–1945. The author used declassified materials from archival documents, but mainly the works of S.N. Aksenov «Irkutsk Aviation Plant. History of Education 1932–1956». The object of the study was the industrial infrastructure of Irkutsk-II (village of aircraft builders), which became the industrial epicenter of the region during the Second World War. The phenomena considered in the study reflect not only regional specifics, but also all-Russian trends. Therefore, some economic indicators of the aircraft industry of that time are given, despite the confidential nature of the industry. On the basis of the study, the author concluded that during the period of 1941–1945, the aircraft industry was the infrastructure-forming industry of the Irkutsk region.

The Influence of Geographical Location and Economic Location on the Industries of Representative Resource Cities in the Pearl River Delta Region

The Pearl River Delta, a prominent economic powerhouse in China, is home to resource-rich cities like Guangzhou, Shenzhen, and Zhuhai. This study explores how geographic and economic location profoundly influence the industrial development of these cities, shaping their economic landscape. Geographic positioning, defined by factors like proximity to coastlines, natural resource distribution, and transportation networks, plays a pivotal role. Coastal cities excel in manufacturing and trade, while those with fertile land thrive in agriculture and tourism. Economic factors such as market demand, labor availability, cost competitiveness, and access to capital also significantly impact industrial composition. These factors interact dynamically, fostering industrial clusters, influencing transportation infrastructure, and guiding resource utilization. Based on these findings, recommendations for optimized industrial planning are proposed, including industry diversification, infrastructure enhancement, environmental considerations, and urban integration. Policy suggestions aim to balance economic growth with environmental sustainability, workforce development, innovation promotion, inclusive growth, and regional collaboration. This research provides valuable insights for policymakers and urban planners to formulate sustainable development policies in the Pearl River Delta and similar regions, ensuring continued economic prosperity.

Statistical knowledge and game-theoretic integrated model for cross-layer impact assessment in industrial cyber-physical systems

Cyberspace intrusions targeting modern industrial cyber-physical systems (ICPSs) are considered highly persistent and stealthy penetration processes that can result in catastrophic consequences for industrial infrastructures. Existing studies predominantly concentrated on detection and defense strategies for specific stages of intrusions without much knowledge of underlying system operational mechanisms, characteristics and evolutionary patterns. In this paper, we present a novel approach that integrates statistical knowledge and game theory to establish a comprehensive security model covering various aspects, including anomaly detection, behavioral analysis, strategy generation and impact assessment. Specifically, a statistical model, i.e. Poisson intrusion model (PIM), is developed to characterize the probabilistic properties of intrusions by leveraging knowledge of their occurrence patterns and frequencies. A Bayesian inference-based model is proposed to analyze the intrusion behaviors for anomaly detection. Then, by integrating statistical knowledge of intrusions and detections, a Markov game model is formulated to characterize the interactive actions and strategies between attackers and defenders throughout the intrusion process. Further, the cross-layer impact is assessed by quantifying the potential consequences under corresponding cyber security conditions in terms of production performance degradation and unintended incident losses. Finally, the proposed approach is validated through extensive experiments for power plant operational scenarios.

Sukuk as an Islamic finance alternative for investment in Infrastructure in Kazakhstan: institutional perspectives

In recent years due to the international economic crisis, the most complex and long-term problems have aggravated in the Republic of Kazakhstan, the resolution of which is strategic importance for the economic well-being of the country and its resilience to external influences. The main goal of further economic development is not only the stabilization and growth of industry, but also the development of industrial and social infrastructure. Nevertheless, issue of infrastructure funding is still open and struggling. As a developing country it takes big deal to borrow from foreign banks. Moreover, the additional leverage appears in a face of currency volatility which is highly distress country economic growth. This paper unveils the actual issues of infrastructure development, adopting Islamic finance in Kazakhstan with legal perspectives and the solution for them in the form of Sukuk issuance model. In this regard, legal perspective should be addressed since regulation on Sukuk is not well accommodated in the existing regulation by both AIFC (Astana International Financial Center) as well as Kazakhstan jurisdiction. Sukuk can expand financial services, assist to develop domestic capital market and provide infrastructure funding without government budget support. Therefore, this paper implies to domestic regulation as set by both AIFC and Kazakhstan mainland jurisdiction.

Morbidity rates of the children population under conditions of aerogenic chemical exposure: risk factors and associations

Introduction. In the the industrialized regions of the Russian Federation one of the hygienic problems is the formation of additional morbidity among the population associated with intense air pollution.
 The purpose of the work is to study the health disorders in children under conditions of aerogenic chemical exposure in terms of primary morbidity.
 Materials and methods. Analysis of the primary morbidity of the children population (data from state statistical reporting and actual seeking medical care in 2017–2021); the content of the main chemical pollutants in the atmospheric air in residential buildings (data from social and hygienic monitoring and the regular observation network of Roshydromet for 2016–2020 according to the content of twenty two impurities); chronic non-carcinogenic risk; connection of diseases with aerogenic chemical exposure according to epidemiological indicators; economic assessment of predicted losses.
 Results. Comparing to the reference area, the level of primary morbidity in children with diseases of the respiratory system, digestion, kidneys, nervous system, osteoarticular apparatus, associated with aerogenic exposure to chemical pollutants, was established to be an increased by up to 3.4 times. In the atmospheric air of residential buildings, the content of a number of chemicals (metals, aromatic and fluorine-containing inorganic compounds) was found to be increased by 6.9 times and 4.0 times relative to the average daily and maximum one-time maximum permissible concentrations, respectively, and within the hygienic standards. The formed exposure causes an unacceptable risk of developing non-carcinogenic effects (HI up to 18.7 times) in relation to target organs. Additional morbidity in the children population (about 1.5 thousand cases per year) has been identified in the event of which the projected economic losses will amount to about 10 million rubles over year.
 Limitations. The study includes the children population under the age of 14 years.
 Conclusion. The primary morbidity of children in regions with developed industrial infrastructure is characterized by special random events associated with aerogenic exposure to risk factors. Projected additional losses require priority regulatory action.

Transformation of innovative development of the double transition to Industry 5.0

Problem setting. The challenge is to significantly accelerate transformational changes through a double transition (digital and green) to Industry 5.0. Analysis of recent researches and publications. Akundi, A., analyzed the state of Industry 5.0 and identified current research trends, Massaro, A., examined advanced management systems in Industry 5.0 that facilitate technological mining Maddikunta, P. and a group of scientists conducted a survey on the technologies and potential applications of Industry 5.0, Gagnidze, I. At the systemic level, he determined whether clusters can cope with the challenges of Industry 4.0 and Industry 5.0, which is also the task of the European Commission and the Manifesto on the double transition in Ukraine. Target of the research. Development of theoretical provisions and practical recommendations for determining the role and importance of Industry 5.0 for the double transition to accelerate the transformation of innovation development. Article’s main body. Priority topics are highlighted, including innovation and digitization, production sustainability, its transformation, and the connection between man and machine. An essential characteristic of the changes that are taking place under the influence of the double transition to Industry 5.0 is the provision of an innovative approach to model-based production management in industry, the introduction of a new concept of advanced process analysis that automates decision-making and optimizes machine settings. According to the European Commission, Industry 5.0 is a key driver of economic and social change, and should lead a double transition: digital and environmental. To determine the level of interest in the transformational changes in innovative development in the context of Industry 5.0, the article uses the Google Trends search service, which provides statistics on interest in several topics simultaneously in space and time. The article conducts a Google Trends search for the topics "Industry 5.0", "European integration", "transformation", "innovative development", "cluster" in Ukraine for the last 12 months (as of August 27, 2023), highlighting the average level of interest and priority regions. The search for the topic of Industry 5.0 in Ukraine over the past year is statistically insignificant. The greatest interest was shown in the cluster and transformation topics, followed by the European integration topic, and the lowest level of interest in innovative development, which is a negative factor. The composition of the priority regions in terms of the identified topics differs: the topic of European integration is more interesting in the western regions of Ukraine, the topic of transformation is more interesting in the central part, and the topic of clusters is interesting in all regions. Conclusions and prospects for the development. The special legal period of martial law is restrictive, which negatively affects the ability to use changes in the technologies of both circular Industry 4.0 and Industry 5.0, but in the current conditions of European integration, on the other hand, there should be an accelerated push for the development of the circular economy. The formation of transformational changes in innovative development in the context of the formation of Industry 5.0 is extremely important in the reconstruction of destroyed industrial enterprises and infrastructure. Post-war recovery requires tools to coordinate stakeholders interested in implementing Industry 5.0 dual transition technologies to strengthen European integration. At the national level, Ukraine needs to focus on the tasks of the double transition to Industry 5.0 by stimulating the development of clusters using European experience.

Economic approaches to assessing the environmental consequences of the war in Ukraine

The article examines the environmental consequences of the war in Ukraine, the types of effects of military actions on the environment and their potential danger to humanity now and in the future.
 The problems related to ecology and climate change as a result of military actions concern not only one country, nation or community, but can also affect the daily life of many future generations of Ukrainians, Europeans and the whole world. The issue of assessing the environmental consequences of military actions, classifying the damage caused, and choosing methods for assessing environmental damage are extremely popular in modern conditions for the Ukrainian and world community, which confirms the relevance and timeliness of this study.
 According to the materials of open sources, it was determined that the main risks for the ecology of Ukraine and the world ecological and economic system were the threat of a nuclear disaster, the impact of active offensive actions on forests, steppes and the natural landscape, the impact of war on plants and animals, the threat to red book species, water pollution and soil as a result of multifactor intervention, hitting industrial facilities and critical infrastructure facilities.
 A comprehensive algorithm for assessing the environmental consequences of military actions has been developed, which includes the following stages: establishment of a list of possible consequences, data collection, data analysis and classification of consequences according to the degree of security, assessment of environmental damage, information exchange and monitoring. Such a sequence allows you to identify the most influential risks and urgently take measures to overcome them. The created algorithm has a consolidated nature and should be refined and supplemented in further work.
 It is proposed to carry out zoning of the territories of Ukraine depending on the possibility of obtaining information about the environmental impacts and consequences of the war and the availability of data collection.
 In the future, it is advisable to develop methods for express assessment of environmental consequences for quick response to violations of environmental requirements, as well as in-depth methods that take into account detailed assessment of consequences and will allow to determine the most accurate economic component of consequences for ecology.

The technical principle and application case analysis of logistics UAV

Driven by multiple factors such as the sharp increase in distribution demand, soaring labor costs, and complex service scenarios, Unmanned Aerial Vehicles (UAVs) have met the basic requirements for practicality and jointly contributed to a "change" in logistics innovation —logistics UAVs. Logistics UAV is one of the typical representatives of the logistics industry's development towards automation and intelligence. After studying two representative logistics and transportation companies in the industry, it was found that the two companies have different positionings for the application scenarios of their respective logistics UAVs, but they have both developed Industry-leading products and technologies through long-term research and development. Although major companies have invested a lot in logistics UAVs in recent years, there are still four major technical problems to be overcome: path planning, automatic obstacle avoidance, battery life and safety. In addition to unavoidable technical problems, factors that hinder the large-scale deployment of logistics UAVs include imperfect commercial markets and imperfect regulatory systems. Although there is still a long way to go for logistics UAVs, logistics UAVs will surely become an indispensable infrastructure for the modern logistics industry in the future, helping the logistics industry to achieve leapfrog development.

Knowledge Communication Strategy in Infrastructure Business

Infrastructure development is a program that usually includes mega projects and involves many stakeholders in its implementation, thus providing great opportunities for knowledge creation. However, the complexity that arises often prevents the creation of knowledge, either through the process of improving existing knowledge or through the process of discovering new knowledge. The process of changing knowledge through knowledge management to facilitate intra- and inter-organizational knowledge transfer has been discussed in various studies on knowledge management, but specific discussion on how to communicate strategies in knowledge management, especially in the infrastructure industry, is still sparse. This study aims to determine how the knowledge management process and public relations program actions in knowledge communication strategy can be adopted. The strategy will motivate systematic efforts to develop information and knowledge and create value in the future. The methodology used in this paper is searching for data and information through books, journals, and articles related to the topic. The results of this paper provide an understanding of the concepts and strategies of knowledge communication in knowledge management and its application to the infrastructure industry.
