Promoting Industriousness and Patriotism among Chinese Youth: Lin Shu's Biography of Two Patriotic Children
Authors: Wen Zhang , Ciaudo Joseph
Published: December 2024

This paper examines the early contributions of Lin Shu (1852–1924) to political debates regarding how one could “save China” by focusing on his engagement with economic and industrial themes through his translation of G. Bruno's The Tour of France by Two Children published in 1907. Unlike most studies that focus on Lin Shu's literary conservatism and his translations’ impact on Chinese literature, the following analysis explores his less-recognized advocacy for practical education and economic development in the late Qing dynasty. By analyzing his Biography of Two Patriotic Children (Aiguo er tongzi zhuan), we argue that Lin Shu promoted industrial and commercial participation as essential for national salvation. This paper highlights how Lin Shu used juvenile literature not only as a didactic tool but also as a medium to foster a pragmatic approach to nationalistic and economic challenges, thereby contributing to a broader understanding of “ shiye” (a term encompassing for Lin Shu all economic activities, including how one concretely engages in work) in the context of China's modern political transformation. Using this approach, this study offers a nuanced view of Lin Shu's works, making him a figure who also contributed to the renewal of political discourses and the language used to debate economic nationalism in early twentieth-century China.

Authors: Usenko Igor
Published: December 2024

Introduction. The hero of our Essay, Mykola Mykolajovich Pavlov-Silvansky, hails from an ancient Ukrainian family renowned for producing many distinguished figures. The genealogy of this family alone warrants separate study. However, the most captivating aspect is the life of Mykola Mykolajovich himself, who played an active role in the social and scientific narratives, contributing significantly to the advancement of Ukrainian academic legal studies and the cultural and educational development in the Poltava region.

He left his mark on state control theory and local history research and eventually fell victim to unjust repression. A thorough examination of M. M. Pavlov-Silvansky’s life and work promises to add new dimensions to the early development of legal research at the All-Ukrainian Academy of Sciences and to begin the process of restoring justice concerning the jurist and his scholarly contributions.

The aim of the article. This article seeks to reconstruct the researcher’s biography scientifically, as well as to clarify and assess his scientific legacy.

Results. Utilizing archival and other sources, we have reconstructed the scientific biography of the researcher. This includes compiling genealogical data on his closest relatives, characterizing his pre-revolutionary work, detailing his contributions to the development of academic legal studies, and his influence on the cultural and educational spheres in Lubny, Poltava region. The study also covers his life and activities after leaving Ukraine and the circumstances surrounding the unlawfully initiated criminal case against him.

Conclusion. While M. M. Pavlov-Silvansky may not be ranked among the most illustrious legal scholars, he was unquestionably a talented scientist, a pioneer who personally laid the organizational and methodological foundations for further research of customary law in Ukraine. He oﬀered valuable insights on several aspects of enhancing domestic state and legal institutions and made significant contributions to the cultural and educational prosperity of his hometown, Lubny.

The legal regime of the territory of the Ukrainian Soviet state during the Ukrainian revolution (1917–1921
Authors: Muzyka Iryna
Published: December 2024

The purpose of the study is to determine the aspects of the scientific analysis of the problem of formation and genesis of the legal regime of the territory of the Ukrainian Soviet state during the Ukrainian revolution of 1919–1921. The problems of the formation and genesis of the legal regime of the territory of the Ukrainian Soviet state during the Ukrainian revolution of 1917–1921, despite numerous publications by scientists of diﬀerent times, remains hotly debated due to the coverage of mainly ideological and formal-legal aspects of the problem.

In 1917–1921, the governments of the UNR, ZUNR, the Ukrainian State of P. Skoropadskyi, the Directory, the Ukrainian Soviet State, each of which performed a legislative function, operated in parallel or alternated on the territory of Ukraine. At the same time, short-term legal regimes were established on the territory of Ukraine in 1917–1921 due to the movement of enemy armies, the formation and movement of military fronts, and the related numerous changes in the power of various state entities in separate parts of the Ukrainian state territory. Legislative acts of the governments of these states in most cases were actually eﬀective only in a small part of the territory controlled by the armed forces of these state entities.

The formation and genesis of the legal regime of the territory of the Ukrainian Soviet state require an objective analysis and characterization of its legal status (federal unit, independent state, part of the territory of another state) at various stages of its formation; administrative-territorial organization and demarcation of borders, taking into account the presence of pseudo-state entities. This should contribute to the prevention of falsifications of history, mythmaking and manipulation of facts, which are the means of the information war of the RF against Ukraine.

Key words: Ukrainian Soviet state, USSR, legal regime of the state territory, border demarcation, Ukrainian pseudo-states of 1917–1920, federation.

Authors: Parkhomenko Nataliia
Published: December 2024

The necessity of conceptualization of law-making activity, providing for its implementation on the basis of common principles and rules in order to form a systematic legislative framework and ensure the complexity of legal regulation, has been argued. This involves the development and adoption by authorized entities of public power, public policy strategy or scientific concept of promising development of the legal array on the basis of clear scientific ideas about the future development and state of the legislative framework, the best ways to improve it.

It is emphasized that the essentially scientific concept should be considered as a system of scientific views on a certain phenomenon, the way of its cognition, understanding and interpretation. Preparation of a scientific concept implies the existence of appropriate analytical skills, skills and experience in a certain area of knowledge of social reality. Accordingly, the creation of the Concept for the Development of Legislation of Ukraine can be carried out by scientific institutions of a legal profile with experience in legislative, scientific and expert work and relevant scientific achievements on the problems of legal regulation of all spheres of public relations, the implementation of legislation in the aspect of determining its effectiveness. That is, they have a systematic idea of the state, the problems of the development of the system of law and the system of legislation that can predict their further development.

Therefore, the Concept of the development of legislation of Ukraine as a predictive document of a public-political nature should determine the strategy of actions of subjects of law-making in the implementation of plans, programs, reforms in the field of law and the list of regulatory legal acts necessary for the development and adoption in chronological sequence, while maintaining the logic of the development of the relevant branch of legislation; priorities in socio-economic development; agree with previously adopted strategic documents (programs, plans, strategies, concepts) of the state level regarding the development of certain spheres of public relations or correct them; provide for the need to develop and adopt only objectively predetermined normative legal acts, avoid unnecessary legal influence. Thus, the Concept defines a plan of law-making activities for the long and short term, and on the other hand — is the result of large-scale monitoring of the current system of legislation.

Annotation: The study presents the results of the research of the impact of traffic intensity and traffic flow composition on the capacity of highways and bridge crossings based on mathematical and numerical modeling methods. The main factors affecting the capacity of highways and bridge crossings have been identified. The methodology for determining the level of traffic and capacity of highways approved by the State Service of Highways (now the Restoration Agency) was adopted as the main calculation basis for numerical modeling. Also, for calculations, updated statistical data, given in open literary sources, were used. 11 test options with different composition of the traffic flow were considered: from 0% to 100% of the share of passenger cars in the composition of the traffic flow. The average speed of the traffic flow was determined depending on the geometric parameters of the road - the radii of the horizontal curves in the plan and the longitudinal slope of the carriageway. It is shown that the average speed of the traffic flow increases with an increase in the value of the radius of the horizontal curve and with a decrease in the value of the longitudinal slope of the carriageway of the road, which is due to the improvement of traffic safety conditions and the possibility of moving vehicles at higher speeds. Also, the results of the numerical modeling showed an increase in the average speed of the traffic flow with an improvement in the level of coverage of the road (bridge crossing). It is shown that an increase in the share of cars in the traffic flow leads to an increase in the average speed of the entire traffic flow, which is explained by their more "compact" dimensions, compared to trucks, buses and road trains. The smallest practical carrying capacity of a highway or bridge crossing corresponds to a column of cars at the speed of free movement. The highest practical throughput corresponds to the traffic intensity at the minimum interval (optimal speed). Also, with an increase in the traffic flow of trucks and large-sized vehicles, the capacity of the road decreases. This determines the relevance of research in the direction of developing load models based on the actual parameters of heavy-duty rolling stock when determining the load-carrying capacity of highways and overpasses.
Key words: highway, bridge crossing, throughput, mathematical modeling.

Published: December 2024

Annotation. Concrete hardening conditions are the main factors affecting the achievement of operational concrete structures properties. Optimal conditions provide conditions for the cement clinker hydration, rate determine of strength gain, reduce the probability of formation shrinkage cracks, and retain a sufficient amount of moisture in the concrete body to increase cracking resistance. In practice, on many construction sites, the ratio of maintenance to concrete hardening is negative. There is no temperature and humidity regime for concrete hardening. Сement clinker hydration can only occur in wet conditions and if there is water in the capillaries of cement stone, it is necessary to create high humidity for concrete hardening to prevent moisture loss due to evaporation. The optimal heat-moist concrete hardening mode helps to reduce the porosity of hydrated cement stone, reduces the pores size and their shape, and increases of concrete microstructure density.

Published: December 2024

Summary. The purpose of the article is to assess the effectiveness of modern methods of diagnosing the operational condition of roads and the possibilities of their improvement using artificial intelligence technologies. The dynamics of the length of public roads in Ukraine for 2017-2022 is considered, which revealed insignificant changes in the total length of paved roads and partial fluctuations in the growth rate. The analysis of the road surface structure showed the predominance of asphalt-concrete roads, while other types of pavement have a small share. A further analysis of the distribution of roads by category showed a higher share of category III roads, which indicates a significant number of medium quality roads that require regular maintenance. The study also examined modern methods of diagnosing the condition of roads, including comparison of indicators with standard values, qualitative assessment of each parameter, and assessment by a generalized indicator. The advantages and disadvantages of each method were analyzed. A detailed review of the most common road diagnostic devices, such as deflectometers, deflectometers and visual inspection units used to determine the strength, flatness, roughness and other operational qualities of the pavement, was also conducted. Based on the analysis, it is proposed to introduce artificial intelligence technologies to improve the accuracy of road condition assessment and automate diagnostic processes. Artificial intelligence is able to integrate data from various sources, including sensors, cameras and satellites, and create complex models to predict pavement wear and determine the optimal timing of repairs. The introduction of such innovations will significantly increase the efficiency of road infrastructure management, reduce maintenance costs and improve safety for road users. As a result, the development of artificial intelligence technologies and their application in road diagnostics is becoming an important area for improving the quality of road infrastructure and ensuring the sustainable development of the transport network.

Published: December 2024

Abstract. The high level of transport safety is important for the development of the country's economy today. International road transport provides a significant share for the functioning of the entire foreign economic activity of the country. Therefore, the increasing level of safety of international road transport is an important issue and it requires attention.
The level of safety of international road transportation is affected by the quality of rest of the drivers who perform such transportation. The work of commercial transport drivers is monotonous, so it can cause a lulling effect even under the most ideal and comfortable conditions. Sharing their experience, international drivers claim: "as if someone is singing a lullaby", "you don't notice when sleep comes." In conditions of fatigue, this effect only increases. Uncontrolled closing of the eyes by the driver for just a few seconds often leads to fatal consequences. After the driver becomes aware of his condition, a quick and inadequate response follows, which in most cases leads to traffic accidents, the consequences of which are: the injury/death of the driver; damage/loss of the vehicle; damage/loss of cargo being transported; the injury/death of other road users; environmental pollution and poisoning of people in case of the transportation of dangerous goods, etc.
To ensure high-quality rest of the drivers of commercial transport and, accordingly, the high level of safety of international road transport in general, there is a need to develop such an element of transport infrastructure as parking and the rest areas for commercial transport.
It is important that drivers do not simply stick to the assigned daily and weekly rest periods but actually rest properly within these periods. During the rest period, drivers should not worry about such issues as: their own safety, the preservation of the vehicle in an intact condition, and the safety of the cargo. The issue of providing drivers with an access to the services, which ensures regular human activities within daily or weekly rest periods is equally important.
Key words: daily rest period, weekly rest period, safety of international road transport, parking and rest areas, commercial transport.

Published: December 2024

Magnesium has received great attention as a potential material for hydrogen storage due to its environmental friendliness, high gravimetric hydrogen storage capacity, and low cost. However, the material's effectiveness is limited by its high thermodynamic stability, which makes hydrogen desorption challenging, and low reaction kinetics, which slows the rate of hydrogen absorption and desorption. To enhance the performance of magnesium as a hydrogen storage material, this work innovatively aims to examine the impact of time and high energy milling speed on particle size as well as the milling aid effect of zeolite 5A. Experiment results showed that after ball milling with 4 h milling time and 270 r/min milling speed, the size of magnesium crystallites calculated from XRD data is in the range of 32.8-49.3 nm, while the size before ball milling was 72.7 nm. The kinetic measurement results showed that the Mg+10 wt.% zeolite 5A+10 wt.% Ni sample with 4 h milling time and 270 r/min milling speed at 330°C and 2.5 MPa had the best absorption and desorption capacity of 4.14 wt.% and 3.91 wt.%, respectively, in less than 25 min. The synergistic effect of milling time, milling speed, and the addition of zeolite 5A with Ni has a significant role in reducing the size of Mg particles, which affects the absorption and desorption performance of magnesium.

Objective

Sciatic nerve injuries often lead to severe pain and motor dysfunction, causing serious impact on patients’ quality of life. Acupuncture, as one of the main therapies in traditional Chinese medicine, is gradually gaining attention in the field of nerve injury due to its potential role in pain relief and nerve repair. Bibliometric and scientific knowledge mapping methods were employed to analyze the current research status, hotspots, and development trends of acupuncture for sciatic nerve injury (SNI) over the past decade.

Methods

A literature search was conducted on acupuncture for SNI from the China Knowledge (CNKI), Wanfang, Weipu (VIP), and Web of Science (WOS) databases, and CiteSpace V6.R6 software and VOSviewer1.6.20 software were employed to analyze and visualize keywords from the collaborative network, keyword co-occurrence, and keyword timeline, respectively. Keyword emergence was analyzed and visualization maps were drawn.

Results

A total of 907 articles were included in the Chinese database, while 78 articles were included in the WOS database. The leading institutions of the literature in Chinese and English were the Liaoning University of Traditional Chinese Medicine and the Institute of Acupuncture and Moxibustion, respectively. Ma Tieming is the most influential person in the field. A keyword analysis of the Chinese and English literature revealed that Huanjiu and Huizhong points are commonly used and that acupuncture is often applied with drug therapy, physical therapy, and rehabilitation training, which can improve the treatment effect comprehensively. Additionally, the therapeutic mechanism of acupuncture mainly promotes nerve regeneration and repair through the modulation of cytokines and related signaling pathways. Electroacupuncture and neuropathic pain are cutting-edge research topics in this field. Based on the keyword emergence, it is predicted that future studies will continue to focus on acupuncture treatment, functional recovery after SNI, and spinal cord injury, which may become the research hotspots in this field. In addition, future studies could further delve into the selection and physiological mechanisms of acupuncture points and validate the effectiveness of this acupuncture and its integrative therapeutic strategies through a wider range of clinical practices.

Conclusion

This study uses visualization software VOSviewer and CiteSpace to provide the current status and trends in SNI of acupuncture over the past decade and predicts potential research frontiers and hot directions.
High-Speed Aircraft Stability and Control Metrics

This review paper identifies key stability and control screening parameters needed to design low-risk, general-purpose high-speed aircraft. These derive from MIL-STD-8785C, MIL-STD-1797, and older AGARD reports, and are suitable for assessing conceptual high-speed vehicles. We demonstrate their applicability using published ground test, computation, and flight test data from the Bell X-2, North American X-15, Martin X-24A, Northrop HL-10, Lockheed Blackbird (YF-12/SR-71), and North American XB-70 as well as the Rockwell Space Shuttle Orbiter. The relative success of the X-15 and Blackbird and the performance limitations of the others indicate the need to scrutinize lateral-directional stability at the preliminary design phase. Our work reveals the need for strong bare-airframe static directional stability to obtain favorable flying qualities.

Galician wheat (Triticum aestivum L.) serves as the foundational component of Galician bread, a traditional Spanish product granted the Protected Geographical Indication (PGI, EU quality scheme), which is primarily conserved at the Agricultural Research Center of Mabegondo (CIAM), Xunta de Galicia, A Coruña, Spain. This study evaluated 20 ecotypes and cultivars, in comparison to 4 Galician wheats and 14 commercial wheat varieties used as references. Seventeen simple sequence repeats (SSRs) were evaluated to elucidate their genetic structure, determine their origins, and differentiate them from commercial cultivars for traceability purposes. In total, 296 wheat plants were analyzed, revealing 156 unique genotypes, 13 of which were from commercial cultivars and 143 of which were from local cultivars and ecotypes. The SSR loci revealed 221 microsatellite alleles, with an average of 11 alleles per locus. Of these, 151 alleles were found in local cultivars and ecotypes, and 134 were present in commercial cultivars, with 65 and 50 alleles exclusive to each group, respectively. A Structure software analysis demonstrated substantial genetic differentiation (Fst = 0.26) between two primary clusters, RPP1 (comprising commercial cultivars, and two ecotypes, 41 and 43) and RPP2 (consisting of local cultivars, elite lines, and ecotypes). Moreover, neighbor-joining tree analysis and principal component analysis (PCA) confirmed the high differentiation between these clusters, highlighting the singularity of Galician wheat, which is useful for the traceability of Galician bread. Furthermore, the SSRs were effective in tracking the use of Galician wheat, which displayed specific Galician alleles, in flour, sourdough, and bread samples, corroborating previous findings even when a greater number of Galician ecotypes were included.
Basalt Rock Dust Amendment on Soil Health Properties and Inorganic Nutrients—Laboratory and Field Study at Two Organic Farm Soils in New England, USA
Authors: Richardson Justin B.
Published: December 2024

Basalt rock dust (RD) is a rock quarry byproduct that may improve soil health in organic farming systems. RD was applied at two contrasting organic farms (the no-till VT-Farm in Thetford, Vermont, and the tilled MA-Farm in Barre, Massachusetts) and in soil batch reactors to investigate the impacts of basalt RD applications (6.7 tons ha−1) on physical and chemical soil health properties. Triplicate soil pits at two fields (RD and no RD) at each farm were sampled down between 80 to 110 cm depths in 2020. Median coarse (>2 mm) and very coarse aggregates (>50 mm) increased by 15% to 25%, and soil organic carbon concentrations increased by 69% to 135% for RD added, compared to no RD, in the top 20 cm of the soil profile at both farms. Plant-available Ca, Mg, and K increased between 62% and 252% in the top 30 cm for both farms. Plant-available micronutrients (B, Mn, Cu, and Zn) showed limited increases from the RD addition at the two farms. The laboratory batch reactor results confirm the increased Ca and Mg release rates tested across soils, but K, P, and the micronutrient batch reactor results did not increase from the RD addition. One contrary finding was (−41% at the VT-Farm) the lower plant-available P and soluble P (−5 to −29%) under the RD addition, suggesting that further studies on the interactions with Fe and pH from the RD addition are warranted.
