Exploring the green and low-carbon development pathway for an energy-intensive industrial park in China

Energy-intensive industrial parks (IPs) exhibit distinct characteristics, including a significant presence of resource-dependent industries, substantial greenhouse gas (GHG) emissions, and severe air pollution. Focusing on energy-intensive IPs and promoting their green and low-carbon development is crucial to achieving high-quality development of IPs. Taking a typical energy-intensive industrial park (IP) in Henan Province—the Red Flag Cannel Industrial Park (RFCP) as the research object, this study applied structural adjustment model, scenario analysis, and synergistic effect evaluation methods to explore the green and low-carbon transition pathway. The GHG and air pollutant reduction potential and synergistic emission reduction effect of the RFCP were comprehensively analyzed under three measures of industrial structure adjustment, energy structure adjustment, and green technology implementation. The scenario analysis indicates that the integrated scenario (S3) shows the most significant emission reduction potential by 2030. Compared to the baseline scenario (S0), the CO2eq emission reduction is 11.66 Mt (53% reduction rate), and the emission reduction rate of air pollutants ranges from 36% to 68% in S3. The synergistic effect evaluation shows that industrial structure adjustment shows the best synergistic control effect on GHG and air pollutants in 2030. The result also indicates that industrial structure adjustment and energy structure adjustment are the main measures to reduce GHG and air pollutants of IPs. Finally, some policy recommendations regarding the transformation direction of energy-intensive IPs were proposed. This study will provide valuable references for the green and low-carbon development of energy-intensive IPs.

Cluster Model for Establishing Special Economic Zones in Ukraine under Modern Conditions (Global Experience)

Object: Clusters are a relatively new form of organization, risk and profit sharing, and competitiveness enhance ment for both the global and Ukrainian economies. The potential of the cluster development model is significant, and, most importantly, it has been justified in developed countries worldwide. In particular, global practice confirms that the functioning of the most prosperous economies is supported by advantages in modern production technologies and man agement. Therefore, successful development of any level is possible through the comprehensive application of modern strategic management concepts. Thus, the object of the study is to reveal and substantiate the effectiveness of cluster model in establishing special economic zones in Ukraine. Methods: The paper uses general scientific and special methods, that are: the dialectical method of understanding cluster model for establishing special economic zones; comparative analysis methods; methods of empirical research, methods of statistical and structural analysis; methods of historical and logical analysis; identifying individual parts of an object, methods of system approach, identifying cause-and-effect relationships. Findings: Custers are established on the base of a unique internal environment and infrastructure specific to a par ticular region. This allows leveraging the competitive advantages of enterprises in a specific area through integration. A cluster serves as a stimulus for economic development, and regionalism forms the basis for its sustainable growth. Re gionalism is of great significance in selecting priority investment areas, as it can influence the level of uncertainty risk during the assessment of regional investment projects. Its effectiveness is confirmed by cluster development of the child nutrition project presented in the paper (Ivano-Frankivsk region, Ukraine). Conclusions: Cluster approach makes it possible to use available resources more efficiently. The cluster approach is connected with the policy of capacity-building as well as increasing competition profitability of national economies. There are also some cluster formations on the territory of Ukraine. Сluster is a convenient form of organizing a free economic zone. At the same time, each government develops its own approaches to the creation of clusters and regula tion of their activities, accordingly, organizes the activities of those responsible for the implementation of the national strategy of sustainable competitive development.

МАРКЕТИНГОВЫЕ ИССЛЕДОВАНИЯ ФАРМАЦЕВТИЧЕСКОГО РЫНКА СЕДАТИВНЫХ ЛЕКАРСТВЕННЫХ СРЕДСТВ, РАЗРЕШЁННЫХ К ПРИМЕНЕНИЮ НА ТЕРРИТОРИИ РОССИЙСКОЙ ФЕДЕРАЦИИ

In the modern world, stressful situations and stress-related disorders have become widespread among the population, representing one of the most pressing medical and social problems. Experts from around the world have traced a clear connection between stress and the development of many diseases, both from the somatic, mental and behavioral levels. Regardless of gender and age, social and cultural status, any person is susceptible to stress, and physical, emotional, informational and/or any other impact can act as a provoking factor [7,8]. When diagnosing disorders caused by stressful events, medical specialists rely on patient complaints arising at the somatic level, without taking into account the mental component, while timely treatment of ordinary stressful conditions that reduce the response adaptive functions of the body, using sedatives, will help to avoid overstrain of the body and prevent the stage of exhaustion [1,7]. The purpose of the study is to analyze the pharmaceutical market for sedative drugs registered in the Russian Federation Federation. During the research, official sources of information on the nomenclature of sedatives were used: the State Register of Medicines, the Register of Medicines and the Vidal Medicines Directory with up-to-date information for 2023. The main analysis methods used in this article are: methods of grouping, retrospective, logical, graphic and structural analysis, content analysis. As a result of the study, the main trends in the development of the range of sedative drugs were determined, and a macro-contour of the pharmaceutical market of the group under study was compiled according to the main leading characteristics of drugs.

Methodological Approach to Comprehensive Assessment of Living Standards in Russian Regions

Introduction. Improving the living standards of the population is the most important task facing public authorities. However, its solution is impossible without a clear understanding of what is meant by this definition and how this indicator should be assessed. Despite the wide representation of studies on this issue, there is actually no unified position and, consequently, no generally accepted assessment. The use of private indicators gives contradictory results. In this regard, the aim of the study is to develop a methodology for the comprehensive assessment of living standards in Russian regions. Materials and Methods. The methods of grouping, dynamic and structural analysis, correlation analysis and others were applied in the framework of the task. The information base of the study was formed by the data of the Federal State Statistics Service of Russia, as well as the works of domestic and foreign scientists in the field under consideration. The research proposed an approach to the formation of an integral assessment of the standard of living of the population of Russian regions, based on a two-stage convolution of 22 private indicators divided into five groups, taking into account the weighting coefficients. Further the methodology was tested on the data on the regions of the Russian Federation. Results. According to the results of the approbation, the ratings of regions by standard of living for 2017‒2021 were formed, which allowed us to consider its dynamics. It was revealed that, in general, the positions of leaders and outsiders remain stable; the differentiation between regions does not decrease. At the same time, while outsiders have weak positions in the overwhelming number of indicators, leadership can be due to different components of the integral indicator. Discussion and Conclusion. The obtained results can be used by the authorities responsible for the development and implementation of state policy in the field of regional development, social security and other related areas. Forecast assessments allow us to identify threats to the realization of the task of improving living standards in Russian regions.

A mixed uncertain structural reliability analysis method considering random and convex set variables with correlation

AbstractIn this paper, a mixed model reliability analysis method is put forward for the problem of assessing the reliability of complex engineering structures containing both random and convex aggregate variables. By integrating the ellipsoidal model with correlation and the interval model, the uncertainty region characterized by the ellipsoidal model with correlation is optimized with full consideration of the limited amount of engineering structure sample data, and the risk region represented by the reliability model is redefined, a new mixed reliability assessment criterion is established, and the minimum safe nonprobability reliability index of the structure is built. A key reference is offered by the safety limit diagram of constant reliability indexes set for the first time for the optimal design of engineering structure reliability. The proposed mixed reliability model is compared and analyzed with three classical models. The sensitivity of nonprobability reliability indexes, influenced by random variable parameters and correlation coefficients, is analyzed. This verification confirms that the new reliability model not only provides an accurate assessment of engineering structures' reliability but also lowers the computational demands of engineering design. In this paper, aero‐engine blades and wind turbine blades are taken as examples to expound the validity of the reliability model built using this method and its importance to the structural safety analysis of actual engineering.

STRUCTURAL POSITION AND DISTRIBUTION OF THE LOWER CRETACEOUS BLACK SHALE DEPOSITS WITHIN THE SILESIAN NAPPE OF THE UKRAINIAN CARPATHIANS

The article presents the results of studying the structural position and distribution of potentially oil-generating, organic-enriched Lower Cretaceous black shale deposits of the Shypot Formation, developed within the Silesian Nappe, using the methods of geological mapping and structural analysis. We concluded, that these deposits, which are exposed in the Vicha River basin near the town of Volovets among a continuous field of Oligocene flysch, are the part of the stratigraphic succession of the Silesian Nappe, and they are not a large olistolith or an allochthonous tectonic remnant of another, more internal nappe. Shypot Formation fills a large (1 × 3 km) subvertical tectonic lens. The rocks of the Shypot Formation are represented here by medium-rhythmic flysch: sandstone beds alternating with dark gray and black foliated mudstone (black shale) layers. They are lithified products of both medium-density turbidite flows and hemipelagic deposition of clayey material with a significant amount of organic matter. In the contact zone of the tectonic lens with the surrounding rocks, the deposits are intensively deformed, almost isoclinal folds with subvetrical hinges are observed, which suggest the strike-slip movements. A tectonic mélange is recorded here, which is represented by small blocks (clastolites) of brittle sandstones, sometimes similar to Shypot sandstones, placed in a silt-pelitic ductile matrix. Foliation of the mélange matrix is also subvertical and close to the meridional and/or subcarpathian direction. The structural studies carried out show that in the zone of this contact there were compressive stresses perpendicular to the Carpathian orogen, and stress fields that caused strike-slip movements, most likely right-lateral along the Carpathian thrusts. The tectonic lens is located within the broad Latorytsa-Stryi shear zone, and probably extruded out from deep horizons by transpressive movements (compression and strike-slip) and forms a “positive flower structure”. The vertical foliation in the mélange suggests that small blocks of Shypot sandstones were extruded up together with the ductile mélange matrix during diapirism. Similar processes probably led to the rise of a large lens of Shypot sandstones as the positive flower structure. The studies suggests that the black shale deposits of the Shypot Formation, enriched with organic matter, are widespread at some depth within the Silesian Nappe, and in some places are pushed up to the level of the Oligocene flysch. As a result, the Shypot Formation and Oligocene flysch are now in direct contact along faults/mélange zones. The presence of Lower Cretaceous potentially oil- and gas-generating black shale deposits within the Silesian Nappe significantly increases the prospects for oil and gas exploration in this area.  

A Structural Reliability Analysis Method Considering Multiple Correlation Features

The paper analyzes the correlation features between stress strength, multiple failure mechanisms, and multiple components. It investigates the effects of different correlation features on reliability and proposes a method for structural reliability analysis that considers the joint effects of multiple correlation features. To portray the stress–strength correlation structure, the Copula function is utilized and the influence of the correlation degree parameter on reliability is clarified. The text describes the introduction of time-varying characteristics of structural strength and correlation parameters. A time-varying Copula is then constructed to calculate the structural reliability under the stress–strength correlation characteristics. Additionally, a time-varying hybrid Copula is constructed to characterize the intricate and correlation features of multiple failure mechanisms and components. The article proposes the variational adaptive sparrow search algorithm (VASSA) to obtain optimal parameters for the time-varying hybrid Copula. The effectiveness and accuracy of the proposed method are verified through actual cases. The results indicate that multiple correlation features significantly influence structural reliability. Incorporating multiple correlation features into the solution of structural reliability yields safer results that align with engineering practice.

Theoretical substantiation of the definition "sports activities of highly qualified athletes"

The article provides a theoretical substantiation of the definition of "sports activities of highly qualified athletes". When forming a new concept, a logical-methodological technology of definition of concepts was used, which provides for the observance of certain principles. The following methods were used during the research: analysis of literary sources and documents; system analysis method; method of comparison and comparison; method of functional and structural analysis. It has been established that the result of sports activity is an effective combination of training of the organs that perform movement, training of the body's functional systems, and perfection of the neuropsychological mechanisms for regulating movements, states, and behavior. The specific features of sports activities of highly qualified athletes are singled out. Attention is drawn to the fact that when evaluating the success of competitive activities, the reliability of athletes' performances at prestigious international competitions becomes important, which indicates not only the level of mental preparation, but is an integral indicator of the evaluation of the athlete's physical, functional, mental, and mobilization qualities.
 The author's definition "Sports activities of highly qualified athletes" is formulated, which is interpreted as a physical and/or mental activity that involves active interaction with the surrounding reality through educational and training training, which includes technical, tactical, theoretical and psychological training and competitive activities to meet the needs and achieving the planned goal.

Hydro- and aero-elastic response of floating offshore wind turbines to combined waves and wind in frequency domain

An analytical approach and numerical solution to determine coupled aeroelastic and hydroelastic response of floating offshore wind turbines of arbitrary shape to combined wind and wave loads is presented. The model considers simultaneously the aerodynamic and hydrodynamic loads on an FOWT and integrates these with finite element method for structural analysis due to the combined loads. The hydrodynamic and aerodynamic loads are determined based on the linear wave diffraction theory and steady blade element momentum method, respectively, and the solution is obtained in frequency domain. The structure may be fixed or floating, located in arbitrary water depth, and may host single or multiple wind towers. The model captures the complete translational and rotational motions of the body in three dimensions, and the elasticity of the blades, tower and the floating platform. To assess the performance of the model, rigid and elastic responses of a FOWT to combined wave and wind loads are computed and compared with available laboratory measurements and other theoretical approaches where possible, and overall very good agreement is observed. The model developed in this study addresses directly three shortcomings of existing approaches used for the analysis of FOWTs, namely (i) determination of the elastic responses of the entire structure including the floating platform, (ii) analysis of the motion and elastic response of FOWTs in frequency domain, and (iii) assessment of responses of FOWTs with single or multiple wind towers.

The Doctrine of the Living Instrument and Evolutionary Interpretation in the Case-Law of the European Court of Human Rights

Relevance. Having developed one of the most complex and advanced human rights protection practices in the world, the European Court of Human Rights has complicated its decision-making mechanism by introducing several doctrines, including the doctrine of the living instrument. The development of the doctrine of a living instrument and an evolutionary method of interpretation in the practice of the Court can be traced to some important cases and problems that have become key and determined the development of the future of the Court itself.The purpose of the article is to analyze the doctrine of the living instrument, the specifics of its application in the practice of the ECHR.Objectives: to analyze various approaches to the study of the nature of the doctrine of the living instrument, to identify trends in the development of evolutionary interpretation, as well as the opinions of various scientists on this issue.Methodology. In the process of working on the study, systematic, comparative legal, historical and legal methods, as well as methods of interpretation, logical and structural analysis were used.Results. It is noted that the concepts of «dynamic interpretation» and «evolutionary interpretation», «the doctrine of intertemporality» and the doctrine of a living instrument should be distinguished. At the same time, there is a risk that the doctrine of the living instrument may violate the sovereignty of Member States if it is used improperly. As a disadvantage, it is also highlighted that this doctrine may damage the legal certainty of the ECHR practice and create a situation where member States do not understand the scope of obligations to which they agree upon accession to the Convention. Based on the nature, it is proposed to divide the evolutionary rulings of the ECHR into 2 categories: rulings of an evolutionary nature and evolutionary rulings.Conclusion. The author concludes that in performing its functions, the Court cannot but apply an evolutionary interpretation, but it must do so reasonably and consistently. The doctrine of the living instrument and the evolutionary interpretation as an instrument of its implementation are a reflection of the generation and those moral values that prevail in society at one time or another.

Generalised scaled boundary isogeometric analysis – a method for structural analysis of naturally shaped timber structures

ABSTRACT Natural building materials, such as naturally shaped tree trunks, have been used in construction since ancient times. Wood is primarily processed as a long, thin product due to its growth and structure, leaving many parts unused. These neglected parts, like branches, can be used for load-bearing structures. However, they require a new parametric description due to material and geometric behaviour differences. It's crucial to transfer these geometries into the calculation model accurately. The surface is described using NURBS based on image data to realise this. Applying the Scaled Boundary Isogeometric Analysis (SBIGA) can directly use these geometries for structural analysis. This method combines the concepts from the scaled boundary finite element method (SBFEM) with the isogeometric analysis (IGA). In this technique, two-dimensional surfaces are scaled to a centre point. When used in the context of thin, long structures, obtuse-angled polyhedrons occur within a patch, leading to numerical condition problems. This motivates this contribution to modify the conventional SBIGA towards a generalised scheme. This work introduces a generalised SBIGA approach, employing a scaling centre line instead of a scaling centre point. This enables the analysis of slender, curved objects without additional structure partitioning, simplifying the preprocessing while improving the performance.

Efficient stochastic modal decomposition methods for structural stochastic static and dynamic analyses

AbstractThis article presents unified and efficient stochastic modal decomposition methods to solve stochastic structural static and dynamic problems. We extend the idea of deterministic modal decomposition method for structural dynamic analysis to stochastic cases. Standard/generalized stochastic eigenvalue equations are adopted to calculate the stochastic subspaces for stochastic static/dynamic problems and they are solved by an efficient reduced‐order method. The stochastic solutions of both static and dynamic equations are approximated by stochastic bases of the stochastic subspaces. Original stochastic static/dynamic equations are then transformed into a set of single‐degree‐of‐freedom (SDoF) stochastic static/dynamic equations, which are efficiently solved by the proposed non‐intrusive methods. Specifically, a non‐intrusive stochastic Newmark method is developed for the solution of SDoF stochastic dynamic equations, and the element‐wise division of sample vectors is used to solve the SDoF stochastic static equations. All of these methods have low computational effort and are weakly sensitive to the stochastic dimension, thus the proposed methods avoid the curse of dimensionality successfully. Two numerical examples, including two‐ and three‐dimensional spatial problems with low and high stochastic dimensions, are given to show the efficiency and accuracy of the proposed methods.

Factors affecting small and medium enterprises access to capital: Evidence from Vietnam

Purpose: The capacity of a business to operate and grow depends on its capital, particularly for small and medium-sized businesses (SMEs). However, access to capital sources depends on many factors such as collateral assets, business plans requiring loans, the social relations of business owners, etc. This study identifies factors affecting SMEs' access to capital in Vietnam.
 Design/Methodology/Approach: A typical survey was conducted on 450 SMEs in Vietnam, and structural model analysis methods were employed through PLS-SEM software to analyze the data.
 Findings: Research results show that there are nine groups of factors affecting the ability of SMEs in Vietnam to access capital  ranked from high to low level of influence, including (i) operational characteristics of the business, (ii) financial reporting, (iii) financial behaviour of enterprises, (iv) social relations of enterprises, (v) capability of the enterprise, (vi) production and business plan of the enterprise, (vii) ability to adapt to the risks of the enterprise, (viii) characteristics of the business owner and the lowest is institutional  environment.
 Conclusion:  Regression analysis proved to be useful in identifying nine groups of elements that impact SMEs' access to capital in Vietnam. The study has proposed management implications to improve access to capital for SMEs in Vietnam.
 Research Limitations and Implications: The study selected samples based on the principle of random convenience, so the study's sample does not represent all SMEs in Vietnam according to the distribution of regions and territories where the businesses are located.
 Practical Implications: This research has practical significance in supporting managers at SMEs to make decisions to improve access to capital for businesses contributing to sustainable business development.
 Contribution to the Literature: This research makes a significant contribution to the field of practical research on capital and capital access for SMEs in Vietnam.

Bayesian active learning line sampling with log-normal process for rare-event probability estimation

Line sampling (LS) stands as a powerful stochastic simulation method for structural reliability analysis, especially for assessing small failure probabilities. To further improve the performance of traditional LS, a Bayesian active learning idea has recently been pursued. This work presents another Bayesian active learning alternative, called ‘Bayesian active learning line sampling with log-normal process’ (BAL-LS-LP), to traditional LS. In this method, we assign an LP prior instead of a Gaussian process prior over the distance function so as to account for its non-negativity constraint. Besides, the approximation error between the logarithmic approximate distance function and the logarithmic true distance function is assumed to follow a zero-mean normal distribution. The approximate posterior mean and variance of the failure probability are derived accordingly. Based on the posterior statistics of the failure probability, a learning function and a stopping criterion are developed to enable Bayesian active learning. In the numerical implementation of the proposed BAL-LS-LP method, the important direction can be updated on the fly without re-evaluating the distance function. Four numerical examples are studied to demonstrate the proposed method. Numerical results show that the proposed method can estimate extremely small failure probabilities with desired efficiency and accuracy.

Perbandingan Kapasitas Kolom Beton Bertulang Berdasarkan Variasi Bentuk Sengkang dengan Analisis Finite Element Method

Columns are one of the structural elements that greatly influence the behaviour of the structure. Columns are capable of holding axial compression loads and transmitting them to the structural elements below. Column capacity can be increased by the confinement of lateral reinforcement/stirrup. The stirrups function to maintain the compressive strength capacity of the concrete column before and after spalling. Advances in software technology have had a very significant impact on the development of structural element analysis methods, including software based on the Finite Element Method (FEM), Abaqus/CAE Student Edition. It can also simplify several laboratory research of Civil Engineering into a simulation. However, in simulation practice, parameters in the form of material data are needed as input. To get the same behaviour between the test object and the simulation, convergent parameters are needed. The parameters to be analyzed are CDP (Concrete Damage Plasticity) plastic parameters. While the simulation for loading, shape of the test object, and placement refers to the results of previous studies. The reinforced concrete column test model used consists of 5 (five) different variations of stirrups. The results of the simulation show that reinforced concrete columns with stirrups provide support in the form of shear force capacity that can maintain the value of the axial compressive strength capacity. From the five existing test models, it was obtained that the increase in the value of the axial compressive strength capacity of the column due to the variation of stirrups for column B, column C, column D, and column E to column A (without stirrups) were 115%, 120%, 121%, and 119% consecutively. The output values from the analysis include the diagrams of axial force and displacement, column interaction diagrams, and material stress-strain diagrams

A new performance‐based seismic design method using endurance time analysis for linked column frame system and a comparison of structural systems and seismic analysis methods

SummaryThis paper presents a new performance‐based seismic design method for the design of repairable linked column frame (LCF) and linked column system (LCS). Currently, the biggest problem of these systems is the lack of a simple and practical design method that leads to the design of optimal models with sufficient seismic capacity. The interaction of the primary and secondary systems, changing the lateral load pattern during an earthquake, and the implementation of the target performance objectives have complicated the design of these systems. The evaluations carried out in this research show that the rotation of link beams must be controlled in the design. Therefore, the ultimate plastic rotation of links is determined to be 0.01 rad for the seismic intensity of design base earthquake and 0.015 rad for maximum considered earthquake. The results show that the models designed using the presented method are optimal, have sufficient seismic capacity, and achieve the target performance objectives. In addition, although previous researches have shown that these systems have a suitable seismic behavior, their seismic behavior have not been compared with other structural systems. Comparing can show the behavioral characteristics of a new structural system; hence, the elastic and plastic behavior of the LCF and LCS models have been compared with other common steel structural systems using all analysis methods. Moreover, in the presented method for the design of LCF and LCS systems, nonlinear time history analysis using the endurance time method (ETM) is used, and due to the newness of the endurance time method, its results are compared with the median results of nonlinear time history analysis at different seismic hazard levels and incremental dynamic analysis (IDA), in 45 samples. The results show that the endurance time analysis is a reasonable and efficient method, and in this comparison, the difference between the results of ETM and IDA methods is 6% on average.
