Authors: Yan Xiaofei
Published: July 2024

The characteristics of cyber-indecent molestation, based on the fact that they are committed over space, are controversial when it comes to determining indecent assault offences. Even though the judicial interpretations provide for some of the criteria for determining cyber-indecency offences against minors, there are still dilemmas in the determination of cyber-indecency offences in terms of the manner of the act, the distinction between the applicable targets of the circumstances, and the aggravating circumstances. In order to further advance the judicial application, the mandatory nature of cyber-space molestation offences should be clearly defined, and the time point for the completion of cyber-space molestation of children should be clarified, so as to further clarify the determination of aggravating circumstances of cyber-space molestation of children, and to construct a typological criminal law application system.

Study of Festival Folklore in Ancient Poems in Chinese Textbooks for Senior Middle Schools: On the Festive Folklore Teaching Strategy for The Charm of A Maiden Singer
Authors: Li Benyi
Published: July 2024

As an intangible cultural heritage, festival folk customs are encountering internal and external troubles. Although it is faded by Chinese people in social life, it is eternally preserved in literary works. According to the new curriculum standard, “cultural inheritance and understanding” is one of the core literacy aspects of Chinese subjects in senior high schools. On this basis, this study probes into the strategy of using Chinese teaching to inherit the “intangible cultural heritage” of festival folk customs. First of all, the connotation of festival folklore should be clarified. Secondly, the content analysis can be used to explore the distribution of festival folk customs in ancient poems in the unified version of Chinese textbooks in senior high schools. Specifically, when it comes to the structure, festival folk customs are non-systematic with limited appearances in ancient poems. From the aspect of content, festival folk customs briefly introduce the festivals and their cultural connotations embodied in the textbooks but neglected by current society. As for the function, festival folk customs can be analyzed from three carriers such as time, folk and emotions for classification. Finally, taking The Charm of A Maiden Signer as an example, the feasible way of integrating festival folk customs into the teaching of ancient poems is proposed. Compared with the general teaching plan, such a design is original, which allows students to experience the national aesthetic tradition of “harmony between man and nature” during the Mid-Autumn Festival with the unique beauty endowed by Dongting Lake. Taking festivals and folk customs as a leadin of teaching can dig out the cultural connotation contained in ancient poems more deeply and accurately, so as to expand the profundity of teaching and improve students’ ability to appreciate ancient poems.

On the Henry James’s Imagination of the Chinese Culture：The Pagoda in The Golden Bowl as an Example
Authors: Nan Zhihan
Published: July 2024

The United States of America in the late 19th and early 20th centuries was a period in which the American nation constructed its own cultural subjectivity. As an important figure in American culture, Henry James created a series of works that focused on the tradition and development of American culture in this process and then played an important role. As a cultural scholar with a global vision, James not only looked at the cultural reality of the United States and Europe, but also did not forget to turn back to the Far East to take a look. His unique and deeply meaningful Oriental imagination is an important reference for us to interpret James's humanistic and cultural outlook. James's cultural attitude toward China in the late 19th century American literature is somewhat unique. He implied his own unique understanding of the oriental culture in his works, as he expressed suspicion, curiosity, and most of all, caution, which reflects James's rigorous cultural concepts and his cosmopolitan cultural thoughts. Because of James's own important position in American cultural history, his attitude is helpful for us to analyze the image of China in American literature and understand American culture at the end of the nineteenth century, as well as the history of cultural exchanges between China and the United States.

Seismic Damage Analysis of Zamora Bridge in Ecuador
Authors: Huang Si , Chen Zhan
Published: July 2024

The Zamora Bridge, located in the Zamora-Chinchipe Province in the southeastern part of Ecuador, on the Pacific Rim seismic belt, serves as the sole river-crossing channel from the Mirador Copper Mine area to the exterior. Constructed and opened for traffic in 2013, this bridge is designed as a low-pier continuous girder bridge, featuring a three-span prestressed concrete continuous box girder for the main beam, with a span arrangement of 45.5+140+45.5 meters, and utilizes basin-type rubber bearings throughout. On May 6, 2019, and November 28, 2021, the Zamora Bridge experienced two significant seismic events. The initial seismic damage investigation revealed that the piers and foundation maintained their load-bearing capacity largely intact; the basin-type rubber bearings predominantly suffered shear failure and displacement, losing their horizontal limit capacity. Additionally, abutment blocks sheared, padstones cracked locally, and the main girder exhibited residual displacement. Following the first earthquake, repair work was undertaken based on the damage results, switching to friction pendulum seismic isolation bearings to enhance the seismic resilience of bridge. The subsequent seismic damage assessment indicated the overall stable condition of the bridge, with no observable damage, deformation, or settling to the main structure, thus maintaining basic traffic functionality. However, shear and deformation occurred to the bolts and pins fixing the direction of the friction pendulum isolation bearings, along with residual displacements after the activation of the seismic isolation function, and cracks developed in the abutment padstones and mortar layers. To delve into the performance and damage probability of vulnerable components of low-pier continuous girder bridges under various seismic intensities, numerical models of the Zamora Bridge equipped with basin rubber bearings and friction pendulum bearings were separately established using OpenSees finite element software. An analysis of the bearings' longitudinal seismic susceptibility was conducted by integrating the demand-capacity ratio and IDA method. The findings indicate that bearings, padstones, and anchor bolts are the vulnerable components necessitating reinforcement for such bridges. Compared to the basin rubber bearings, friction pendulum bearings significantly reduce the probability of bearing damage and demonstrate an excellent seismic isolation effect.

Published: July 2024

In order to solve the problem of cuttings bed in the drilling process of highly deviated sections in directional wells, horizontal wells and extended reach wells, an Effective HydroClean Drill Pipe(EHCDP) was designed, using computational fluid dynamics (CFD) simulation techniques, the flow characteristics of the annular flow field under the action of EHCDP were analyzed, the cuttings removal efficiency of this kind of EHCDP under different deviation conditions is studied, thus providing the relevant basis for using this EHCDP to remove cuttings more efficiently. The results show that the EHCDP can effectively remove cuttings under different deviation conditions. However, the larger the inclination angle of the well, the more likely the cuttings is to accumulate on the lower edge of the wellbore due to gravity, forming cuttings bed. In highly inclined wellbore above 60°, EHCDP can be combined with traditional cuttings removal methods to more effectively remove cuttings near the low side of the wellbore.

Authors: Xu Dong , Luo Yang
Published: July 2024

A series of eutectic high-entropy alloys Ni(60-y)Fe20Co10Cr10Aly (y = 0, 5, 10, 15, 20, 25) were synthesized via non-consumable vacuum melting, followed by investigation into their solidification microstructures and compression properties. The research results reveal that the solidification microstructures transition from a well-distributed FCC phase (y-0, y-5) to a coarse FCC+B2 isometric crystal structure (y-10), subsequently to a primary FCC phase with a (FCC+B2) eutectic structure (y-15), succeeded by a predominant B2 phase with a (FCC+B2) eutectic microstructure (y-20), and ultimately to a BCC+B2 biphasic structure characterized by periodic braided sheets (y-25). The FCC phase demonstrates a substantial concentration of Ni and Fe, the BCC phase shows substantial enrichment primarily in Fe and Cr, while the B2 phase exhibits significant enrichment in Ni and Al. As the Al content increases, the alloys exhibit higher strength but reduced plasticity. Specifically, alloys with y values of 20 and 25 exhibit yield strengths of 1012 MPa and 1477 MPa, respectively, coupled with remarkable plasticity of 41 and 23%, thereby demonstrating robust mechanical properties.
Study on Variation Law of Ground Pressure before and after Hard Roof Fracturing
Authors: Yang Shuhao
Published: July 2024

Hard roof has the characteristics of small fracture development, good structural integrity and strong integrity, and the hanging roof area is large during mining, which seriously threatens the safety production of working face.Based on the characteristics of hard roof such as high strength, large thickness and difficulty in self-caving, directional drilling hydraulic fracturing is adopted to destroy the structural stability of hard roof and make it reach an ideal fracture form. At the same time, the variation law of strata behavior in working face before and after fracturing of hard roof is explored.The results show that:①During the normal weighting period of hard roof working face, the support pressure of working face is generally small, but when the hard roof is broken, it will cause the phenomenon of strong weighting in working face, which threatens safe production;②Hydraulic fracturing leads to secondary development of primary fractures in hard roof and continuous diffusion in the form of fracture network, which destroys the original bearing structure of hard roof and forces hard roof to collapse ahead of time;③Thirdly, comparing the weighting law of working face before and after fracturing, it is found that after pressure relief, the initial weighting step of working face decreases by 50.8 m, which is 56.4% year-on-year, and the average periodic weighting step decreases by 3.7 m, which is 21.4% year-on-year. After pressure relief, there is no strong strata behavior in working face, and hydraulic fracturing achieves the expected effect.

The deformation properties of rock are closely related to the effect of crack closure, generation and expansion in the rock. In this paper, the stress-crack strain evolution constitutive model is used to determine the relaxation damage zone of the surrounding rock based on the change regulation of the crack closure ratio during the whole process of surrounding rock damage, and the model is embedded into FLAC3D software, and then the stability evaluation of the surrounding rock of the cavern group under unsupported and supported conditions is carried out for the underground plant of Yebatan hydropower station. The excavation simulation shows that the displacement of the cavern surrounding rock increases with the excavation step, and the influence of the fault on the displacement of the surrounding rock is very significant. The high stress concentration area is distributed in the arch top of the plant, the tailwater connection hole, the arch top and the bottom of the tail chamber, and the tensile stress area is mainly distributed in the high side wall of the underground plant and the tail chamber. The crack closure ratio index was used to quantitatively evaluate the degree of relaxation damage of the surrounding rock, indicating that the relaxation damage area is influenced by the fault, and the volume of the surrounding rock damage area under the system support is significantly reduced compared with the unsupported working condition, showing the effectiveness of the support measures.

Z kolei ust. 2 przywołanego artykułu stanowi, że po śmierci twórcy, spadkobiercy mogą sprzeciwić się egzekucji z prawa autorskiego do utworu nieopublikowanego, chyba że sprzeciw byłby niezgodny z ujawnioną wolą twórcy co do rozpowszechniania utworu. Przepis ten wprowadza daleko idące ograniczenia egzekucji, a jego wykładnia i zastosowanie w praktyce przez organy egzekucyjne budzi wiele wątpliwości. Celem niniejszego artykułu jest analiza art. 18 pr. aut. i określenie zakresu stosowania wspomnianego przepisu, jak również przepisów postępowania egzekucyjnego na gruncie k.p.c., w szczególności instytucji zajęcia komorniczego autorskich praw majątkowych. Zdaniem autorki konstrukcja art. 18 pr. aut. wprowadza daleko idące ograniczenia w egzekucji z autorskich praw majątkowych, co potwierdza szczególne uprzywilejowanie twórcy. Celem artykułu jest również rozważenie tej problematyki w odniesieniu do możliwości zajęcia komorniczego nośników rzeczowych praw autorskich. W tej kwestii autorka stawia tezę, iż zakaz egzekucji wyrażony w art. 18 pr. aut. nie dotyczy co do zasady nośników rzeczowych, będących w jej ocenie rzeczami w znaczeniu cywilistycznym. Niemniej jednak sprzedaż egzemplarza może być niekiedy rozpowszechnieniem utworu i stać w opozycji z zakazem wyrażonym w art. 18 ust. 1.

Biodegradable films based on poly(vinyl alcohol) (PVA) and bioactive substances have been receiving great attention in the food industry, as they offer an eco-friendly alternative to conventional packaging. In this context, we synthesized PVA (PVAF) films containing silk fibroin (SF) formulations functionalized with copaiba oleoresin (CO) for use as bioactive packaging. Four different formulations were prepared using the casting method, varying the SF-CO concentrations from 0 to 15% (v/v) in the PVA matrix. The samples were characterized regarding morphology, nanotexture, physicochemical, and barrier properties. SEM images revealed the uniform morphology of the films, and AFM data allowed the quantification of surface characteristics such as uniformity and homogeneity, confirming the uniform distribution of SF-OC in the PVA matrix. All films showed high water absorption power (more than twice their mass weight), and the incorporation of SF-CO did not change the water vapor permeability rate of PVAF. In contrast, the solubility of PVAF decreases with SF-CO content. FTIR and UV-vis spectra confirmed the presence of SF-CO in PVAF and indicated possible intermolecular interactions between PVA and SF-CO. Finally, our findings suggest that the incorporation of SF-CO into the PVA matrix is a viable alternative for producing eco-friendly packaging.

Bull fertility plays an important role in improving the economic value of the herd and is measured in terms of semen quality traits, which is influenced by both genetic and non-genetic factors. Polymorphism of MAP3K1/ CviQI (rs463712269), SPEF2/HpyCH4V (rs722354121) and PLCZ1/AvaII (rs208019489) and their association with scrotal circumference, sperm motility and plasma membrane integrity, respectively were studied on 239 bulls of different breeds reared in different frozen semen bull stations. The MAP3K1/CviQ1 assay revealed that T allele was more frequent in Ongole and Murrah population. RFLP at SPEF2/ HpyCH4V locus indicated fixation of T allele in both the exotic purebred cattle (Holstein Friesian and Jersey) whereas selective advantage of C allele was observed in Murrah buffaloes. Except in Holstein Friesian crossbred, other cattle genetic groups were with CC genotype for PLCZ1/AvaII assay and the Murrah population had low genetic diversity and heterozygosity excess. The PLCZ1/ AvaII genotypes had significant influence on the plasma membrane integrity of sperm in Holstein Friesian, Jersey and Ongole bulls. The plasma membrane integrity of sperm was reported to be high in heterozygotes (CG) of Jersey and Ongole cattle. The present study, concluded the importance of PLCZ1 gene as a marker for semen quality assessment and selection in bulls.
Challenges and Prospects for the Law of Armed Conflict — A Humanitarian Perspective
Authors: Ouyang Wenting
Published: July 2024

The law of armed conflict, as the international legal system that regulates the conduct of war and mitigates its catastrophic consequences, has in recent years faced the challenges of high-tech forms of warfare, the involvement of non-state actors, and the complexities of civil-military integration. To address the complexity of non-international armed conflict, international humanitarian law should be “strategically” disseminated, non-government parties should be urged to issue unilateral declarations or codes of conduct, and the UN Security Council Action Plan model and the Geneva Call’s “Deed of Commitment” model should continue to be explored and implemented. The distinction between combatants and civilians in cyber-armed conflict requires more attention to actual behavior than to the appearance of the operator, with full consideration of the relationship between full membership and function. For the use of autonomous weapons systems, we must balance military interests and the consequences of damage, maximize the recognition and decision-making capabilities of autonomous weapons systems, and maintain human oversight and control during high-risk decisions.
Challenges to Socio-Economic Balance in Istanbul’s Rapid Urbanization
Authors: H. B. Nilay , S. A. Onur
Published: July 2024

Istanbul, a city of significant historical and geographical importance, has experienced rapid urbanization over the past few decades. This paper explores the socio-economic challenges that have arisen from this urban expansion, focusing on housing shortages, infrastructure strain, economic disparities, social cohesion issues, and environmental degradation. Using a mixed-methods approach, the study integrates qualitative insights from in-depth interviews and field observations with quantitative data from structured surveys and secondary sources. The findings reveal that while urban renewal projects and infrastructural investments have modernized parts of the city and attracted investment, they have also led to the displacement of long-term residents, exacerbated economic inequalities, and stressed existing infrastructure. Comparative analysis with other rapidly urbanizing cities like Mumbai, São Paulo, and Shanghai provides valuable lessons for addressing these challenges. The paper concludes with policy recommendations aimed at promoting inclusive and sustainable urban development in Istanbul, emphasizing the need for equitable housing policies, strategic infrastructural investments, community engagement, and the adoption of smart city technologies.
