Published: May 2024

The oomycete Phytophthora cinnamomi Rands is the mean responsible for oak decline in southern Spain. This paper investigates the relationship between phosphoric fertilization of Quercus ilex and Q. suber seedlings and resistance to the disease caused by Phytophthora cinnamomi. The study was conducted on holm oak and cork oak seedlings previously submitted to a phosphoric fertilization programme involving four different treatments, namely: Phosphate-A (3 mg P2O5 seedling), Phosphate-B (6 mg P2O5 seedling), Phosphite (0.15 mg de P2O5 seedling) and No Fertilization. Tests were conducted in greenhouse over a period of 7 months and a number of treatments to plants inoculated with Phytophthora cinnamomi Rands. were applied, assessing the changes in their morphological (viz. height, root and collar diameter, and secondary root biomass) and physiological characteristics (viz. leaf nutrient contents). Based on the results, phosphate failed to improve plant resistance to P. cinnamomi; by contrast, phosphite successfully avoided infection by this pathogen. In fact, the phosphitetreated plants exhibited a morphological and physiological status similar to or even better than that of the non-inoculated controls. The protective effect of phosphite against P. cinnamomi can be achieved by applying it during seedling cultivation in nurseries.

Authors: Huang Zicheng
Published: May 2024

Researches on the effect of bilingualism/diglossia on academic performance conclude disparately yet converge on the children of early school age. This research aims to figure out the longer-term influence of Cantonese usage on academic performance by conducting a large sample survey and the Chinese reading literacy assessment of PISA 2018 on 100 young citizens aged 18 to 25 in Guangdong province. In addition to reconfirming the vastness of Cantonese-Mandarin bilinguals in Guangdong province, China, The Language History Questionnaire 3 detected a categorically strong dominance of Mandarin in the Cantonese districts of Guangdong. Nevertheless, it is still not suggested that the Guangdong parents preclude Cantonese from family language planning out of worry about the childrens academic performance, drawing on the result that no negative effect of Cantonese usage was found in the correlation test.

Analysis of the Insurance Applicant's Obligation of Truthful Disclosure
Authors: Pan Kelin
Published: May 2024

Since China implemented the reform and opening-up policy in 1978, the insurance industry has gradually embarked on a path of sustained growth and development. In 2001, China joined the World Trade Organization, ushering in an unprecedented era of expansion and diversification in the insurance industry. Against the backdrop of increasing public risk awareness, insurance has become an important tool for individuals seeking to mitigate potential losses in their risk efforts. However, this trend has also raised concerns about the ethical and legal responsibilities of insurance companies. A common dissatisfaction expressed by policyholders is that there is a difference between the optimistic description of insurance products during the sales process and the refusal of claims for false reasons after risks occur. This phenomenon has raised doubts about the true disclosure obligations of insurance companies under the Insurance Law and the necessity of improving transparency and accountability in insurance transactions. This study aims to delve deeper into this complex issue by examining the legal framework of policyholders' true disclosure obligations under the context of insurance contracts. By doing so, it seeks to contribute to the ongoing legal reform discussions within the insurance industry, with the ultimate goal of promoting a more fair, transparent, and harmonious insurance ecosystem that benefits all stakeholders.
Self-Preservation and Salvation: How Democracy Functions in a Disenchanted World
Authors: Li Xun
Published: May 2024

The concept of "disenchantment" (Entzauberung) was first mentioned by the famous German poet Johann Christoph Friedrich von Schiller in his poem The Gods of Greece. In the poem, he mentioned that the gods in mythology ruled over man and all creatures, the world was full of beauty and love, and all things performed miracles. When Christ God became the only God, the miracles faded, and mankind was lost. Disenchantment theory and democratic institutions are central to Max Weber's theory. On the basis of combining the two, this paper studies how democracy functions in a disenchanted world from two perspectives: self-preservation and salvation. Findings suggest that democracy can inject some elements of quasi-charisma into an otherwise spiritually deadened situation. In a post-disenchantment world, a democratic system led by a strong leader will save people's spiritual world in a mutually empowering way through both self-preservation and salvation. Self-preservation within democracy signifies individuals' expression of free will through leader selection. Salvation in democracy entails placing trust in elected leaders to bring about happiness and national prosperity.
On the Protection and Inheritance of the Evenki Ethnic Culture
Authors: Liu Shuying , Rui Yujia
Published: May 2024

In previous studies of the Evenki ethnic group, different perspectives have been presented regarding the research on Evenki language culture in various historical contexts and research periods: researchers from each era exhibit differences in research directions, angles, and awareness of issues. These differences are closely related to research objectives, external backgrounds, power relations, and the development of disciplines in different eras. This article suggests that an analysis of the Evenki language not only helps us understand the changes in ethnic language forms over different periods but also allows us to observe people's psychological states and practical needs against the backdrop of the times. In the context of today's era, this can effectively enhance our adaptability to linguistic and cultural transformation, and desktop research is a rapid method of reading literature and collecting language information categorization. The article demonstrates that the desktop learning research method proposed surpasses current typical language learning methods, helping us better adapt to the intelligent society and the era of big data.
Exploring Self-Construction of the American International Image: A Conceptual Metaphor Perspective
Authors: Wang Fengyuan , Duan Chengcan
Published: May 2024

While press releases and cultural transmission materials are common materials for understanding a country's self-construction of international images, to what extent the speeches at international conferences are effective in shaping national images is yet to explore from a perspective of cognitive linguistics? The present study compiles the minutes of 26 meetings of the United Nations Security Council on the situation in the Middle East, including the Palestinian issue, from which the speeches by U.S. representatives were selected to establish a corpus, and explores the self-construction of the American international image with conceptual metaphor theory. It is found that JOURNEY metaphor, BUILDING metaphor and so on are instrumental in shaping its image of advocating peace, but SEED metaphor and NEIGHBOR metaphor, etc. reveal its intention to perpetuate the conflict and double standards in dealing with the two conflicting parties.

Published: May 2024

The evolution of software architecture has witnessed the transition from monolithic to microservices, offering enhanced scalability, maintainability, and flexibility. With the rise of Microservices Architecture (MA), containerization has emerged as a pivotal technology to encapsulate microservices in isolated environments, ensuring consistent deployment. This paper delves into the intricate relationship between Microservices Architecture and containerization, focusing on the benefits, challenges, and practical implications of integrating both. Through a comprehensive experimental setup simulating an e-commerce platform, we quantitatively evaluate the performance metrics of a containerized microservices system versus a traditional monolithic setup. Our findings accentuate the performance gains achieved through MA and containerization, while also shedding light on areas that demand caution and further research. The insights presented serve as a beacon for organizations aiming to transition to or optimize their microservices and containerization practices.

Published: May 2024

The formulation of a calcined clay-based hydraulic binder is an innovative solution for reducing the carbon footprint in the construction industry. This binder is made from calcined clay, a natural and abundant material that does not require high-temperature firing in the 400C to 950C range. In our study, we worked respectively under the following temperatures: 550C, 650C, 750C and 850C, unlike traditional binders whose clinker is fired at a temperature of around 1450C. The blaine tests showed that the binder had been well ground, resulting in a much finer binder. We then obtained various blaines varying between 5000 and 8000 Cm2/g, unlike the blaine of the traditional binder, which is 3800 Cm2/g; the residue rate is very high compared with that of the traditional binder, due to the grinding carried out in a laboratory ball mill. The results of resistance tests at 30% gave 34.8, 48.8, 36.5 and 46 respectively; those at 40% gave 42.7, 45.4, 44.4 and 44.8, while the resistance of traditional binder gave 42.5. In other words, we obtained strengths comparable to those of the traditional binder. In addition, it was found that the manufacture of calcined clay-based hydraulic binders reduces CO2 emissions compared with traditional binders, which emit very high levels of CO2, making the production of calcined clay-based binders a more environmentally-friendly option for the cement industry. The financial assessment carried out at the end of this study shows that the production of a calcined clay-based binder is more economical than that of a traditional binder (Portland cement).

Published: May 2024

Speaking is a highly prioritized skill in English language learning, particularly in tourism. Storynomics is an approach in tourism that emphasizes storytelling, creative content, and living culture, utilizing culture's power as a destination's fundamental essence. This study aims to examine how the storynomics strategy can promote the’ speaking competence of tourism students in Bali. The study employed Research and Development (R&D) with an Exploratory Mixed Method design. Quasi-experimental research was applied to determine the effectiveness of the material design for students in the Tourism Management Department. The students were divided into two groups of 30 students in each group. The data were obtained through pretest and posttest speaking tests after the treatment was given. The result of the test indicated there is a significant difference between the two groups. The experimental group taught the storynomics strategy throughout the study to promote speaking ability, while the control group continued with conventional methods. At the end of treatment, a posttest was conducted in two groups, and the test results were compared. Statistical analysis showed that the experimental group obtained a higher average score in the posttest with an N-gain score of 0.58. These findings emphasize the positive impact of implementing a storynomics strategy in learning English as a foreign language, especially for describing local culture. It is expected that further development can be made in designing other teaching materials using a cultural approach and more diverse communication strategies with other theories or approaches. In addition, a deeper analysis is needed regarding the linguistic aspects of English language learning in the field of tour guiding.

Introduction:

A pronounced gender imbalance is evident among orthopaedic surgeons. In the field of arthroplasty, there exists a dearth of comprehensive data regarding gender representation. This study aimed to analyze the gender diversity, or lack thereof, within the field of total hip arthroplasty (THA). In addition, this study used literature review to identify possible reasons for the gender disparity among THA surgeons and identify the best next steps to promote gender equity within orthopaedics.

Methods:

A retrospective analysis was conducted using the Medicare Provider Utilization and Payment Data: Physician and Other Practitioners data set to quantify orthopaedic surgeons who performed primary THA procedures from 2013 to 2020. To assess trends in the number of hip surgeons by sex and the evolving female-to-male ratio, two-sided correlated Mann-Kendall tests were conducted.

Results:

Overall, 3,853 to 4,550 surgeons billed for primary THA annually. Of this number, an average of 1.7% was female. The mean number of services billed for by male surgeons was 31.62 ± 24.78 per year and by female surgeons was 26.43 ± 19.49 per year. Trend analysis of female-to-male ratio demonstrated an increasing trend of statistical significance (P = 0.009). The average number of procedures by female surgeons annually remained stable throughout the study, whereas there was a steady increase in that for male surgeons.

Conclusion:

Results showed a notable and sustained upward trajectory from 2013 to 2020 in the number of female surgeons billing for THA along with the female-to-male ratio. However, female surgeons constitute a mere 2% of surgeons engaging in primary THA billing. Furthermore, the annual average number of THAs conducted by female surgeons exhibited constancy, whereas there was a gradual increase in the median number of annual procedures performed by their male counterparts. Future studies should aim to identify and resolve specific barriers prohibiting female medical students from pursuing and obtaining a career as an orthopaedic THA surgeon.

The Reconciliation Policy Factory in the Mediterranean Area: Transitional Justice as a Model for Managing a Violent Past (Part II)
Authors: Gamurari Vitalie , Abdelaziz Mukhtar
Published: May 2024

The Maghreb space was and remains a specific one, conservative and little affected by European democratic processes, despite the fact that it has secular traditions with European states, especially with France, Spain and Italy. The last decades of the 20th century have radically changed the mentality of the class politics of this region, including thanks to external factors, but also internal ones, dictated by the visions of the new generation influenced by Western democratic values. However, the reconciliation process of the Maghreb countries’ societies cannot be viewed outside of the evolutionary processes that strongly influenced the respective political regimes and produced major effects on the progressive changes in the interest of the citizen. At the same time, we cannot examine the respective societies as a package, each of them having its own traditions, be it political, legal, cultural or social. In such conditions, the practice accumulated by the Maghreb countries in the implementation of transitional justice, the final objective being national reconciliation, is of increased interest for post-conflict societies, including the Republic of Moldova.

Authors: Soliman Nesma , Fahmy Reham , Adl Mohamed
Published: May 2024

The current study was conducted to evaluate the cardioprotective potentials of eugenol against hypertension induced by doxorubicin in rats. Rats were exposed to Doxorubicin HCl (2mg/kg body weight) intraperitoneally to induce cardiotoxicity and treated with eugenol (5 mg/kg) orally for 5 weeks. At the end of the study, the blood pressure was assessed in the tested animals and the levels of serum lipid profile and oxidative stress markers were assessed. Also, the heart was dissected and the oxidative stress and apoptotic markers in heart homogenate were assessed. There was high statistically significant difference between all the tested groups regarding the systolic blood pressure and mean arterial pressure. The Serum oxidative stress markers and lipid profile markers showed a statistically significant increase in the positive control group compared to other groups. The heart homogenate level of all the tested parameters showed a statistically significant increase in the positive group compared to other groups except for the MDA levels that was comparable between the positive group and protection group. Eugenol's antioxidant and lipid-lowering properties protect against hypertension. Eugenol's antioxidant and anti-apoptotic effects protect the heart from hypertension's long-term effects at the tissue level.
CSGA: A DUAL POPULATION GENETIC ALGORITHM BASED ON MEXICAN CAVEFISH GENETIC DIVERSITY
Authors: Alkafaween Esra , Hassanat Ahmad , Essa Ehab , Elmougy Samir
Published: May 2024

Genetic algorithms (GAs) are search algorithms based on population genetics and natural selection concepts. Maintaining population variety in GAs is critical for ensuring global exploration and mitigating the risks of premature convergence. Rapid convergence to local optima is one such challenge in the application of genetic algorithms. To address this issue, we provide Cave-Surface GA (CSGA), an alternative method based on the Dual Population Genetic Algorithm and inspired by the genetic variety observed in Mexican cavefish. Through inter-population crossbreeding, CSGA increases diversity via a secondary population (Cave population) and facilitates the exchange of information between populations, effectively counteracting premature convergence. Several experiments are carried out utilizing benchmark instances of the Traveling Salesman Problem (TSP) obtained from TSPLIB, a well-known TSP problem library. Our experimental results over many TSP instances show that CSGA outperforms both classic GAs and other GAs that use diversity preservation techniques, such as Multipopulation GA (MPGA). CSGA has the potential to give promising solutions to challenging optimization issues like TSP.

Theoretical Study of Radical Scavenging Antioxidant Activity of Coumarin Derivatives in Licorice Using DFT
Authors: Luo Linghuan , Xia Pengpeng , Zeng Dongdong
Published: May 2024

Nowdays, much research is focused on exploring antioxidant activity based on natural compounds. Licorice, a traditional natural product rich in antioxidant components, has been widely used in clinical medicine. However, there is a lack of theoretical studies on the active components in licorice. In this context, the antioxidant activity of several common active components of coumarin derivatives in licorice was investigated using a density flooding theory (DFT) approach. The free radical scavenging ability of the compounds was achieved by hydrogen atom transfer (HAT), sequential electron transfer proton transfer (SET-PT) and sequential proton loss electron transfer (SPLET) mechanisms. The effect of solvent on antioxidant activity was also investigated. It was found that in the gas and benzene phases, the compounds studied preferred to undergo the HAT mechanism, while SPLET was favoured in polar solvents. In addition to the above mechanism, the HOMO and LUMO energies of the compounds as well as molecular descriptors and electrostatic potential maps were calculated and applied to predict the antioxidant activity of the compounds. The above studies allow a better understanding of the mechanism of free radical scavenging activity of coumarin derivatives from licorice.

In policies related to hydrogen energy, we cannot keep up with the times. Only some policies are specifically targeted at solar photovoltaic and wind power generation, and some policies are even temporary. These fiscal policies are severely lagging and lack uniformity, which not only weakens the overall effect of the money supply, but also to some extent hinders the healthy and rapid development of the hydrogen energy industry. In addition, the national development plan, including national and local plans, cannot be well connected, resulting in some policies not forming strong support for hydrogen energy. In these industrial plans, production capacity targets account for the majority, but there is a lack of refinement of utilization targets and little mention of the development balance of the industrial chain.

Published: May 2024

The safety of civil engineering structures such as bridges and buildings is paramount, necessitating the early detection and repair of cracks to prevent structural failures. Traditional crack detection methods, including manual inspections and basic image processing, are often hampered by slow detection speeds and limited accuracy. This study explores the integration of advanced deep learning techniques, specifically MobileNetV2, enhanced through transfer learning, to improve the efficiency and accuracy of crack detection. The "Concrete Crack Images for Classification" dataset was employed, featuring 40,000 images from real-world scenarios. Our approach leverages the lightweight architecture of MobileNetV2 and the efficiency of transfer learning to create a robust model that not only reduces computational demands but also achieves high accuracy, with a validation accuracy rate of 99.38%. This paper details the model training, the innovative use of MobileNetV2, and comparative analyses with other deep learning models, demonstrating significant improvements over traditional methods. The findings underscore the potential of MobileNetV2 and transfer learning in practical applications, offering a promising avenue for future research in automated crack detection across various engineering fields.

Published: May 2024

Este artigo tem o objetivo de analisar a utilização de estratégias de alfabetização e letramento em sala de aula, partindo do pressuposto sobre os desafios da alfabetização e letramento nas séries iniciais. Assim, os passos da leitura analisarão os princípios pedagógicos e teóricos implícitos nos atos de alfabetizar e letrar para que, instrumentalizados, todos os educadores, possam enfrentar os desafios que a prática alfabetizadora exige em sala de aula. Nessa perspectiva, a leitura e a escrita constituem práticas reconhecidamente valorizadas no âmbito da sociedade, visto que os usos da língua oral e escrita remetem à possibilidade de participação social no partilhamento de um bem cultural que é a escrita. Portanto, uma questão de cidadania, ao tempo que se revela como uma forma de inclusão social, ao possibilitar a capacidade criadora e o posicionamento crítico no mundo onde estamos inseridos.  O objetivo é compreender como se desenvolve o processo de construção da aprendizagem da leitura e escrita, observar as práticas pedagógicas dos professores que atuam neste ciclo e identificar as dificuldades encontradas na alfabetização. O estudo foi desenvolvido a partir de referencial bibliográfico que trata da construção da escrita, leitura e da alfabetização, principalmente estudo de caso, com abordagens estratégicas. A aprendizagem da língua escrita e leitura é resultado de um lento processo de construção. Essa construção depende da vivência dos alunos em contextos sociais que valorizam estas práticas sociais.

Realizou-se uma pesquisa com 53 dentifrícios que já estão no mercado com critério de seleção de apelos promocionais nos rótulos sobre a formulação, uso de óleos essenciais e ingredientes naturais. Os produtos foram encontrados em drogarias e lojas de produtos naturais nos municípios de Itu e Salto, como também em lojas virtuais (e-commerces) que comercializam produtos nacionais e importados. A tabulação foi feita em software google formulários, com posterior análise comparativa utilizando o Teste de Turkey com pós teste de Bonferroni, assumindo o P<0.05 para os dados obtidos e analisados. Por fim, o artigo revisou dentro da literatura as evidências científicas sobre uso do flúor, parabenos, triclosan, ingredientes naturais , componentes estes encontrados na maioria das amostras analisadas. Conclui-se que as dosagens de flúor seguem as recomendações e diretrizes de agências reguladoras do país, bem como de outros componentes presentes nos cremes dentais avaliados neste estudo. O uso de produtos naturais e de cannabis ainda não apresentam eficácia científica comprovada.
