According to stoichiometric estimates, less than half of the protective resource of an insulating mask with chemical oxygen redundancy is used by the moment of critical breakthrough of exhaled СО2 through the regenerative cartridge. One of the causes is the destruction of the porous structure of oxygen-containing product granules affected by exothermic heat emitted during the chemisorption of exhaled СО2 molecules. The second cause is the dead layer of the product remaining unused by the end of the protective action of the gas mask when air with 1.5 % carbon dioxide content starts leaving the regenerative cartridge. In order to eliminate these causes, mathematical and computer modeling of air regeneration in the gas mask for chemically bound oxygen with a hybrid (circular pendulum) air duct design and enlarged granules of potassium superoxide at the inlet to the regenerative cartridge have been performed.
It has been shown that the enlargement of granule size by 25 % reduces by more than one-third the rate of heat emission in them when binding exhaled СО2 molecules, which softens the cartridge's thermal regime and preserves the granules' porosity. The length of the part of the cartridge with enlarged granules is determined based on the condition of the equal rate of СО2 absorption at the inlet to the first and second (with non-enlarged granule size) parts of the cartridge.
The efficiency of the use of the breathing device’s protective resource is also increased by the reverse of airflow in the dead layer of oxygen-containing product. The length of the pendulum part of the regenerative cartridge that ensures the maximum (by 8.1 %) increase in the use of the product’s dead layer and prevents air filtration through the spent layers of oxygen-containing product has been determined.

Published: February 2025

Preventing methane fires is one of the main challenges of fire safety systems in thermal power plants. The analysis of existing fire prevention systems at energy facilities demonstrated their low efficiency. It has been proposed to consider the use of thermally activated water for methane phlegmatization in case of accidental leakage in the enclosed volume of the energy industry facilities with the application of mathematical modeling.
Based on the calculations, the number of technical devices of supply for non-leak-tight rooms of various degrees has been established. When a certain coefficient of non-leak-tightness is reached, which corresponds with aquatic medium supply in metastable phase state to the open space, the number of trunks will be maximum for a given volume. It is practicable to install supply devices of water medium in metastable phase state on lateral surfaces, whereas phlegmatizing concentrations are achieved within 10 sec from the moment of supply. It has been established that the existing systems of fire prevention are not efficient enough as in some cases these may lead to the occurrence of explosive local areas. A method to prevent combustible gas fires with aquatic medium in a metastable phase state in enclosed volumes of energy facilities has been proposed and theoretically substantiated. The necessary number of technical devices to supply thermally activated water depending on the room volume and non-leak-tightness coefficient have been calculated. Using the software and hardware package Pyrosim has confirmed the correctness of performed calculations and helped to identify the optimal method of supplying aquatic medium in metastable phase state to the volume of the engine room of a thermal power plant.
The Bride Price as a Symbol of Abjection
Authors: Akhter Tawhida , Abdullaziz Khalil Suad
Published: February 2025

Abjection, a term developed by French philosopher Julia Kristeva, refers to being excluded or cast out from something considered sacred or pure. It’s associated with feelings of disgust, shame, and humiliation. Buchi Emecheta’s novel The Bride Price 1976 delves into the female identity and shows how the woman is being changed into abject because of the oppression and subjugation. Bride price, also known as dowry, is the practice of transferring wealth from the groom’s family to the bride’s family upon marriage. It can be seen as a symbolic exchange, potentially representing the value placed on the bride. The bride price could be seen as a way of marking the bride as an object of exchange, potentially reducing her economic value and causing a sense of abjection. Studying The Bride Price is significant for several reasons: It helps us understand the cultural context and historical origins. It aims to examine the ways in which gender relations are constructed and maintained through cultural practices. The paper investigates Abject as a concept developed by Julia Kristeva in The Powers of Horror 1982, which refers to a feeling of disgust or horror. The Abject disrupts our established categories and systems of meaning. Emecheta bride’s use of price might evoke feelings of disgust and threaten our sense of self and social order. This paper also attempts to analyze the experience of the female characters and shows how mortality and decay are an abject which threatens human boundaries and disturbs the identity.

Published: February 2025

The prevalence of chronic kidney disease worldwide has been reported to increase every year with hypertension serving as the leading cause. The recommended treatment for chronic kidney disease patients with a history of hypertension is antihypertensive medications, which could cause side effects from prolonged use. Hence, the authors sought out a possible novel modality by implementing antioxidant properties from beard lichen (Usnea spp.) extract. Literature search was conducted on trusted scientific databases, including Google Scholar, PubMed, DOAJ, and Cochrane. The pathophysiology of hypertension in the progression of chronic kidney disease could mainly be attributed to the presence of inflammation and oxidative stress, which could be attenuated by the use of antioxidants. Lichens are a class of complex living organisms resulting from a symbiosis that allows them to synthesize various beneficial phytochemicals. Usnic and stictic acid derived from Usnea spp. are part of phenolic compounds that display strong antioxidant activities. In order for these antioxidants to have a focused effect on the kidneys, a kidney-targeted drug delivery system should be considered with lysozyme conjugation being the most studied method. The combination of Usnea spp. extract’s antioxidant capabilities with lysozyme conjugation could serve as a potential novel modality in the specific prevention of chronic kidney disease progression.                 Keywords: antioxidant; chronic kidney disease; lysozyme conjugation; Usnea                       spp.

Published: February 2025

One of the most popular pharmaceutical preparations for the eyes today is in situ gel. The in situ gel system is a system that is liquid at room temperature but will form a gel when it comes into contact with the body or undergoes a change in pH. The form of the drug delivery system is in-situ is a type of mucoadhesive drug delivery system. Gel formation depends on several factors such as temperature modulation, pH changes, the presence of ions, ultra-violet irradiation, electrical sensitivity, and the enzyme by which the active substance is released. The purpose of this study is to compare the therapeutic efficacy of in situ gel medicines on pH, temperature triggered, and ion activated gelling systems. A drug in situ gel is a drug delivery device that transforms into a gel after being applied to the body. The findings revealed that the pH, temperature triggered, and ion activated gelling system factors had a substantial influence on the extended release medicines that affect the therapeutic effect of in situ gel medications. This comparative investigation demonstrates that the pH, temperature triggered, and ion activated gelling system factors have significant implications on the therapeutic benefits of in situ gelled medicines. A deeper knowledge of the relationships between these variables and in situ gel drug delivery methods can lead to the development of more effective and dependable medication compositions. These findings could aid in the development of improved gel in situ drug delivery systems to improve therapeutic benefits in the treatment of a variety of medical disorders.  Keywords: in situ gel, pH triggered, temperature triggered, ion activated, therapeutic effect.

Authors: Stoica Paula , Giurma Ion , Zaborilă Anca , Giurma-Handley Catrinel-Raluca
Published: February 2025

In recent years, GIS methods have been successfully applied to determine watershed characteristics and shape. Drainage density, the total length of streams per unit area, impacts surface hydrology and reflects climatic effects on terrain. It is associated with hydrologic processes like infiltration, soil saturation, and runoff. This paper aims to enhance processing time and accuracy in determining drainage density using GIS. By applying various GIS functions, a grid network from a digital elevation model is converted to a vector file, revealing the drainage density of the Liwiec watershed. Higher drainage density correlates with lower infiltration rates and higher surface flow velocity, often indicating more sediment transport, higher flood peaks, steep slopes, and low agricultural potential. The study’s findings support future management planning in the area.

Authors: Sococol Ion , Mihai Petru , Petrescu Tudor-Cristian , Luca Bogdan-Ionel
Published: February 2025

Reinforced Concrete (RC) Frame structures are one of the main Seismic-Resistant (SR) structural systems used by structural engineers. In these conditions, the current research study highlights the importance architectural-structural conformation of Moment-Resisting (MR) RC Frame structures in preliminary seismic design stage, so that in the current practice often results MR RC Frame buildings with increased sensitivity to earthquake. Thus, the seismic response of this structural system type required to real earthquakes was studied in parallel with seismic design specifications for RC structures, developed in P100-1 and EC 8 seismic norms. The observations regarding the effects of the inadequate architectural-structural conformation of the MR RC Frame structures overlapped with examples of real structures executed in the Iasi area (Romania). Thus, it was concluded that non-compliance with the conditions of architectural-structural conformation of MR RC Frame systems leads to seismic design of the building for lower values of seismic action and non-existent high ductility of the structure. In these conditions, the lateral structure develops a non-ductile seismic response with local and global collapse mechanisms (general torsion; weak floor/ground floor).

Published: February 2025

Because of the high amount of concrete used everywhere in the world, and the big necessity of aggregates and cement the science community has to come with a solution for this problem. The article presents a study of self compacting concrete using recycled aggregates, in this case brick dust, for satisfaction of mechanical properties. Self compacting concrete seems to be the best solution to stop pollution when we talk about concrete because it doesn’t need compacting technologies and offers the opportunity to add to it in limited dosage recycled aggregates or fly ash as substitution of a small portion of cement. The study presents a number of 18 recipes who are using brick dust divided in three categories according to the dimensions of particles such as: 0-4mm; 4-8mm; 8-16mm. The brick dust is replacing the same category of aggregate in three separate percentages: 10%, 20% and 30%. The replacement of cement with fly ash has also been done for the 18 recipes in two percentages: 5% and 10% and the results for fresh state and mechanical properties and density is discussed.

Published: February 2025

Inappropriate disposal of wastewater including heavy metals may lead to serious public health problems. Among conventional wastewater treatment methods, adsorption is the preferred treatment technique, due to its advantages such as cheapness, simplicity, and flexibility in design and operation. In recent years, there has been an urgent need toward the production of low-cost alternatives to the commercial activated carbon which has a greater adsorption capacity with high porous and large surface area. In this experiment, activated carbon that derived from pine cone (PCAC) has been investigated as a new adsorbent to remove copper(II) ion from wastewater. The adsorption process of copper(II) ion from aqueous solution was carried out in a batch mode to study the effects of adsorbent dose (0.5 g/50 mL - 2 g/50 mL), initial pH (2-8), and initial concentrations (5 mg/L - 20 mg/L). The results indicated that activated carbon obtained from pine cone was an efficient adsorbent for the copper removal from the aqueous solution. Removal of copper ion from aqueous solution was dependent on the adsorbent dosage, pH, and initial Cu concentration, achieving maximum adsorption efficiency (99 %) at 2 g/50 mL, 6, and 20 mg/L, respectively.

Authors: Li Lili , Chung Wonjun
Published: February 2025

In recent years, with the rapid development of the economy and the acceleration of urbanisation, urban construction, and rural construction have achieved a positive interaction, and the landscape development resources and development needs of urban and rural areas have also been constantly gathered and integrated, and gradually formed a unique urban-rural integration landscape style. However, the inherent contradictions in urban and rural development are still difficult to alleviate fully and have caused serious obstacles to the visual transmission of urban-rural integration landscape style. There are differences in culture, economy, and lifestyle between urban and rural areas, and the current landscape design approach finds it difficult to find an effective balance between preserving and promoting traditional rural culture and meeting the living needs of modern urbanites. To solve this problem and improve the visual communication effect of urban-rural integration landscape style, based on the analysis of the definition, constituent elements, and visual communication requirements of urban-rural integration landscape style, combined with Artificial Intelligence (AI) technology, this paper has conducted in-depth research on the visual communication of reuse design and green environment-friendly urban-rural integration landscape style. The experiments were carried out from three dimensions: feature extraction, visual communication effect, and environmental and economic benefit coefficient. The results showed that in terms of visual communication effectiveness, compared to traditional models, AI-based integrated urban and rural landscape visual communication had an average score of 0.77 and 0.70 points higher in terms of aesthetics and harmony, respectively. From the specific numerical results, it can be seen that the method in this paper can effectively improve the visual communication effect of reuse design and green environmental protection urban and rural integration landscape style, and promote the healthy development of urban integration landscape.

Authors: Kokolaki Georgia , Panselinas Giorgos , Papadimitriou Sofia
Published: February 2025

The ‘e-mediating’ or otherwise ‘five-stage’ instructional design model for e-learning focusses on the construction of knowledge through the gradual development of socialisation. The study in hand aimed to capture the socialisation as it develops in an asynchronous teacher training course in Digital Literacy, designed and implemented with the five-stage model. Specifically, the study investigated not only the development or lack thereof socialisation but in which tool (where), at which stage (when), and with which messages/posts (how) it occurred, thus trying to investigate what helps and what hinders its development in such a context. Data were collected by using the message analysis technique used by Jones & Peachey (2005) in a similar study. The results showed implications on the role of the trainer, on the importance of the social organisation and design of the e-tivities, and finally on the role of the digital tools used.
Insights about social identities from health professional students in interprofessional experiential learning: A qualitative approach / Soziale Identitäten von Studierenden der Gesundheitsberufe im interprofessionellen Erfahrungslernen: Eine qualitative Studie
Authors: Anderson Olivia S. , Edwards Hannah , Mattison Debra , Smith Laura J. , Eze Chinwe E.
Published: February 2025

Background

Interprofessional education (IPE) provides students with opportunities to consider the impact of effective collaboration on patient outcomes. Socializing beyond one’s own profession in an interprofessional team challenges the social identity theory that postulates favoring those within the same group, or, in this case, the same health profession. The social identities that learners form before entering a degree program may impact team socialization. We describe how students considered their social identities while interacting in an interprofessional team and engaging with patients in experiential patient-centered learning.

Methods

Students (n=139) representing 11 health professions worked in interprofessional teams to interview patients about living with chronic illness. Students reflected on how their social identities may impact team and patient interactions before and after the interviews. Responses from the written student reflections were collected for data analysis.

Results

Before the interviews, students reported that social identities may be advantageous for teamwork, allow for diverse perspectives, raise cultural awareness, provide relatability with patients, and bring awareness to biases. Following interviews, students reported increased awareness of their own, peers’, and patients’ social identities.

Conclusions

Intentionally encouraging students to reflect on their social identities and how these influence collaboration with peers and patients contributed to their interprofessional socialization.

Authors: Rawat Akshat , Athikkal Sivaprasad , Saahithi S , Subburaj Vivekanandan
Published: February 2025

Short-range wireless DC-to-DC power transmission using a switched capacitor converter (SCC) for various voltage ranges is presented in this letter. In wireless power transfer (WPT) applications, the main factors to consider are the target’s distance from the source coil and the voltage received at the load. In this work, the receiving voltage can be varied according to the application by selecting the voltage ratios (VRs) using the multiphase controller. The different VRs are selected using the Fibonacci series having the arbitrary value of (0, 1). A proposed circuit is designed and simulated using SIMULINK to validate the proposed WPT converter and to verify its transfer efficiency. The constituent blocks of the transmitter and receiver modules are designed, simulated, and examined for WPT. In many studies, step-up voltages are presented and discussed, but not the step-down WPT. This letter discusses the wireless power supply system with different step-down/step-up VRs, which can be used to supply auxiliary systems such as battery charging, audio systems, mobile phone calls, and general voltage regulators. The proposed converter with WPT provides high efficiency, voltage regulation, and target distances. The power of the proposed converter varies from 80 μW to 100 μW for the input voltages 12 V–24 V.

Published: February 2025

Development is an integral part of research, since the study of specifics and characteristics in such a unique topic as the quality of processed products cannot be done without extraordinary equipment, fixtures and a laboratory. Laboratory equipment has been created that combines all hardware aspects of the development of the quality of processed products, where it analyzes the quality of workpieces that depend on the processing technology. However, this depends largely on the technological system used. The paper includes measurements, data acquisition and back-checking of the logic of the study of grinding operations. In the introduction, it must be shown that the correct selection and strength characteristics of the tool associated with the cutting mode of grinding determine the accuracy and quality of the surfaces of the ground part. The impact on the service life of the grinding tool was also monitored. The 4th partial result is also the knowledge that the correct selection of the tool characteristics and cutting mode predicts the quality of the workpiece surface. The operating conditions of the manufactured parts significantly affect the operating values of the production parameters. By appropriate diagnostics in the research process and precise measurements using sensitive sensors, deviations can be minimized. Without this apparatus, it is possible that deviations increase significantly during the operation of the technological system. The size of the deviation during grinding is explained in practice by the presence of vibrations in technological processes. They cause instability of the parameters of the technological system. To stabilize the quality indicators, a mathematical apparatus was also used, which takes into account changes in the technological regime. They are determined by designing adverse conditions, e.g. restoration of the cutting properties of a worn grinding wheel. Therefore, its replacement is logically carried out earlier than its replacement is planned.

Authors: Kayouh Nabil , Dkhissi Btissam
Published: February 2025

Supply chain resilience is a critical determinant of success in the automotive industry, particularly in emerging markets like Morocco. This research employs a comprehensive approach to identify and prioritize external logistical risks threatening automotive supply chains in Morocco. Through interviews with logistics specialists of multinational automotive companies, we utilized the fuzzy Analytic Hierarchy Process (AHP) and the fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to assess the weights of evaluation factors and rank the identified risks, respectively. Our findings reveal that catastrophic events in the factory, extreme weather conditions, and workers’ strikes/labor union issues are the top three risks posing the greatest threat to supply chains in Morocco. Additionally, challenges such as agitated political situations, high maintenance costs, and infrastructure limitations demand attention to enhance supply chain resilience. This research contributes to the understanding of supply chain risk management in emerging markets and offers practical insights for industry practitioners and policymakers aiming to fortify automotive supply chains in Morocco and similar contexts.

Do Perceptions About the Causes of Poverty and Wealth Shape Attitudes Towards Progressive Taxation? An Exploratory Analysis for 2021 Romania
Authors: Dragoman Diana , Raţ Cristina
Published: February 2025

Lying at the backbone of European welfare states, taxation is both an enabler of redistribution and a predilect means of fiscal welfare. Among Central and Eastern European countries, Romania was an early adopter of flat rate taxation two decades ago, in 2004. As Kovács (2022) convincingly argues, in terms of net wages this shift led to less revolutionary outcomes than expected; however, it clearly diminished the tax burden for middle and higher wages, while those on lower wages paid gradually bigger taxes, as deductions eroded. By 2021, opinion polls indicate that three quarters of Romanians show support for progressive income taxes (Friedrich Ebert Stiftung, 2021: 20). Which socio-economic and demographic factors shape this attitude? The present paper offers an exploratory analysis of the relation between perceptions about the causes of poverty and wealth and being in favour of progressive income taxes in one of the most unequal and impoverished countries of contemporary Europe.
The Path from Romania to the Italian Domestic Care Sector: The First Stage of the Decisionmaking Process on Labour Migration
Authors: Harabagiu Irina-Miruna
Published: February 2025

This paper aims to propose a multi-stage model for the decisionmaking process on labour migration that takes into account both individual agency and structural dimensions along political-institutional, economic, and social factors. While it is focused on the case of Romanian women’s migration to the Italian domestic care sector, it can be applied for the analysis of other types of labour migration too. From a historical perspective, Romania underwent major political, economic, cultural, and social transformations after 1989 and throughout the years of EU integration and membership, that influenced transnational labour migration. With the help of relevant population statistics and qualitative interviews with Romanian women working in Italy, I illustrate how the three structural dimensions contribute to the start of the individuals’ decision-making process on migration. The political-institutional dimension both enables a culture of labour migration and conditions or disinhibits the possibility of migrating abroad for work. Through a series of disruptions, the economic dimension creates distress, which brings certain individuals in a state of needing alternative solutions to ensure their livelihood. As they search for solutions, these people will be exposed to the option of labour migration. This exposure, however, takes place in the social dimension, which represents the aggregate of individuals’ social relationships. Finally, by assuming the roles of mentors and/or migration facilitators, social actors influence individuals to become aspiring migrants and to follow a migratory destination. Considering working abroad as an option (available, needed and possible) represents the first stage of a decision-making process that the individuals go through. At the end of it, the actors will become from aspiring migrants- novice labour migrants.

Published: February 2025

This article explores how to improve operational performance in maritime ports by managing the flow of goods effectively. This study proposes an innovative approach based on Reinforcement Learning (RL), specifically the Monte Carlo Tree Search (MCTS) method, to address the restricted container relocation problem (RCRP). This method aims to determine an optimal sequence for container retrieval based on their respective priorities, in order to minimize the number of necessary relocations. By employing precise actions and a defined reward function, MCTS is guided towards the best possible solution. The efficiency and relevance of this method are demonstrated through various solved scenarios and compared to a literature-based approach using genetic algorithms. The results show that the MCTS approach is effective in addressing the complex challenges of goods flow management in maritime ports.
Enhancing Public Transport Accessibility for People with Motor Disabilities Through Deep Learning on Graphs
Authors: Turno Francesco Maria , Jackiva Irina Yatskiv , Budiloviča Evelīna
Published: February 2025

Globally, over a billion people live with disabilities, facing significant challenges in accessing public transport, which impacts their autonomy, social participation, and economic status. Current research indicates that common problems include inadequate service in terms of destination, timing, and travel duration, as well as physical barriers at stops and the behaviour and proficiency of transit staff. These issues are exacerbated for those with visual impairments or mobility challenges, such as wheelchair users, who face even greater obstacles. This research emphasizes the necessity of an “enabling transport” environment that considers all aspects of travel for those with limited mobility. This includes the physical layout of pedestrian routes, the design of buildings, and the functionality of public transportation systems. Practical measures like aligning bus floors with pavements, as mandated in the European Union, and optimizing the deployment of accessibility equipment like pallets are discussed as essential for improving access. The authors propose a research methodology that employs a graph-based approach in combination with recurrent neural networks models to suggest most accessible pathways considering fleet availability, vehicle capacity and road quality of sidewalks. The approach includes a comprehensive case study in Riga, Latvia, utilizing data from local transport operators and crowdsourced information to assess and address physical barriers. This innovative application of deep learning on graphs aims to significantly improve the inclusivity and efficiency of public transport for people with disabilities. The study emphasizes the broader benefits of creating accessible environments that improve usability for all citizens, not just those with disabilities.

It is proposed that an organic molecule can be characterised by a «property vector» of the following form:
E =  ( D P   Ha/Hd Ea/Ed La/Ld)  [sqrt(energy/mole)] (1)
The terms of this vector show the ability of the molecule to attract other organic molecules: D: by dispersion forces and P: by the inhomogeneity of its electrical field. The remaining terms symbolise properties in which forces between two molecules exist only if one of them is an acceptor, the other a donor: Ha/Hd: interaction by displacement of a nucleus of the donor towards the acceptor («hydrogen bridge»), Ea/Ed: by displacement of «one» electron in one molecule towards the other («charge transfer») and La/Ld: Lewis acid-base type interaction.All terms beside D should be small and in any case not greatly exceed the magnitude of sqrt(RT). In this case a linear combination of the interaction forces (LCID) is admissible as approximation to calculate the resulting force as shown by the equations (2), (3), (4) and (5). Note that P is defined to represent an additional effect to D furthermore H, E and L represent additional effects over D + P.Existing polarity scales are discussed in the light of the method of LCIF in a qualitative manner.

Рассмотрены методологические аспекты и общие принципы организации регионального экологического мониторинга. Авторами отмечается, что основные положения и цели программы глобальной системы мониторинга были сформулированы в 1974 г. на Первом межправительственном совещании, на котором первоочередной задачей была признана организация мониторинга загрязнения окружающей природной среды и вызывающих его факторов воздействия. При этом говорится, что наибольший интерес для крупных городов России представляет региональная подсистема, основанная на следующем принципе: выбор ее состава и структуры осуществляется, исходя из физико-географических, гидрометеорологических и иных особенностей территории с учетом уровня и масштабов развития промышленного производства, автотранспорта, состояния городских и сельских поселений и др., и направленная на решение следующих задач: оценку состояния среды с целью «инвентаризации» природных и природно-техногенных территорий и объектов в масштабах всего региона; определение «горячих точек» на карте региона – промышленных объектов с высоким уровнем выбросов (сбросов) загрязнений; решения проблем управления отходами производства и потребления.

The article deals with methodological aspects and general principles of regional environmental monitoring. The authors note that the main provisions and objectives of the program of the global monitoring system were formulated in 1974 at the first intergovernmental meeting, at which the organization of monitoring of environmental pollution and its causing factors was recognized as a priority. At the same time, it is said that the regional subsystem based on the following principle is of the greatest interest for large cities of Russia: the choice of its composition and structure is based on physical and geographical, hydro meteorological and other features of the territory, taking into account the level and scale of development of industrial production, motor transport, the state of urban and rural settlements, etc., and aimed at solving the following problems: assessment of the state of the environment for the purpose of «inventory» of natural and man-made territories and objects throughout the region; definition of «hot spots» on the map of the region – industrial facilities with high emissions (discharges) of pollution; solutions to the problems of production and consumption waste management.
АДАПТАЦИЯ МЕТОДОЛОГИИ ПОСТРОЕНИЯ ПРИРОДОПОДОБНЫХ ГОРНЫХ ТЕХНОЛОГИЙ ПОДЗЕМНОЙ РАЗРАБОТКИ РУДНЫХ МЕСТОРОЖДЕНИЙ К УСЛОВИЯМ КРИОЛИТОЗОНЫ

Рассмотрены экологические особенности разработки жильных месторождений цветных, редких и драгоценных металлов и установлено, что на современном этапе развития геотехнологии модернизация горного производства производится исключительно в направлении повышения экономических показателей, а вопросы сохранения биоты или только декларируются, или решаются по остаточному принципу в виде бесконечной борьбы со следствиями, без устранения причин. Обоснована необходимость кардинальной смены парадигмы взаимоотношений техно- и биосферы на основе биологического императива. Создана методология адаптации принципов построения природоподобной геотехнологии подземной разработки рудных месторождений к особенностям криолитозоны, включающая в себя: основание методологии и ее логическую структуру; основные методологические принципы, вытекающие из концепции природоподобия, а также обоснование методологических решений, соответствующих условиям разработки многолетнемерзлых месторождений. Предложена принципиально новая концепция построения геотехнологий, обеспечивающих возможность реализации биологически обоснованных ограничений и обеспечивающих сохранение естественной биоты Земли при освоении минеральных ресурсов ее недр в условиях Арктики и Субарктики.

Ecological features of development of vein deposits of nonferrous, rare and precious metals are considered and it is established that at the present stage of development of Geotechnology modernization of mining production is made only in the direction of increase of economic indicators, and questions of preservation of biota or are only declared, or solved on the residual principle in the form of infinite fight against consequences, without elimination of the reasons. The need for a radical change of the paradigm of relations between the techno - and biosphere on the basis of the biological imperative is substantiated. The methodology of adaptation of the principles of construction of natural-like Geotechnology of underground mining of ore deposits to the features of the cryolithozone, including: the basis of the methodology and its logical structure; the basic methodological principles arising from the concept of natural similarity, as well as the justification of methodological solutions corresponding to the conditions of development of permafrost deposits. A fundamentally new concept of construction of geotechnologies, providing the possibility of implementation of biologically justified restrictions and ensuring the preservation of the natural biota of the Earth in the development of mineral resources of its interior in the Arctic and Subarctic.
