Abstract.To study the influence of different water-cement ratios and graphene oxide doping amounts on the mechanical properties of concrete. In this test, graphene oxide concrete with 4 water-cement ratios (0.35, 0.38, 0.41, 0.44) and six graphene oxide dopings (0, 0.02%, 0.04%, 0.06%, 0.08%, 0.1% (cement mass)) were prepared for mechanical properties. The results show that graphene oxide has a significant enhancement effect on the mechanical properties of concrete. As the water-cement ratio increases, the compressive strength and splitting strength of concrete show parabolic changes that first rise … Read more →

Abstract.To investigate the effects of different water-cement ratios and carbon fiber content on the compressive and splitting tensile strength of concrete, this experiment was designed with four water-cement ratios and four carbon fiber contents. The four water-cement ratios were 0.35, 0.38, 0.41, and 0.44, while the four carbon fiber contents were 0%, 0.3%, 0.6%, and 0.9%. The experimental results showed that: 1. The compressive strength and splitting tensile strength of concrete initially increased and then decreased with the increase in water-cement ratio and carbon fiber content, reaching their … Read more →

Abstract.The "National Curriculum Standards for Ordinary High School English (2017 Edition, 2020 Revision)" puts forward a series of new requirements for high school English teaching, emphasizing that teachers should cultivate students' core English literacy in the process of English teaching, including students' language ability, cultural awareness, thinking quality, and learning ability. The design of writing new question types after reading echoes the concept of the new English curriculum standards and is an effective measure to cultivate students' core literacy in the English subject.  Therefore, … Read more →

Abstract.This paper studies the hybrid application of carbon nanotubes (CNTs) and nano-SiO₂ sol in cement-based composites. Using water-bath ultrasonic dispersion technology, CNTs/SiO₂ composite fillers were prepared to enhance cement composites. The results show that carbon nanotubes (CNTs) can be uniformly dispersed in cement-based composites with nano-SiO₂ sol as the dispersion medium. When the contents of SiO₂ sol and CNTs are 1.50wt.% and 0.15wt.% respectively, the mechanical properties of cement-based composites are improved most significantly. Read more →

Abstract.With the issuance of the "Senior High School English Curriculum Standards (2017 Edition)," there have been more changes and requirements for high school English reading instruction. Project-based learning, as a new teaching model, requires teachers to experiment with and adapt their reading instruction methods to improve the quality of reading education. This paper primarily focuses on senior high school English reading instruction based on project-based learning. The study first clarifies the issues and significance of this research and discusses its theoretical foundation; it then employs … Read more →

Abstract.Permeability is an important parameter that controls the seepage capacity of sandstone layers. The complexity of the pore structure and the strength of heterogeneity in sandstone affect the accuracy of permeability prediction. Fractal dimension can analyze the pore space structure of real rock samples from multiple dimensions and different perspectives and describe the characteristics of the pore structure. This study takes six groups of sandstones as the research objects and comprehensively uses thin section identification, HPMI (high-pressure mercury injection) experiments, and fractal … Read more →

Abstract.With the in-depth advancement of educational reform, high school English teaching is also constantly evolving and innovating. As a new type of writing task, continuation writing has attracted widespread attention. Compared with traditional English writing, continuation writing requires students to possess higher abilities in understanding the text, writing output, and the connection of the plots. Under the guidance of the core literacy, high school English teaching not only focuses on imparting language knowledge but also aims to cultivate students' language abilities, thinking qualities, and … Read more →

Abstract.In order to investigate the bonding performance of the interface between prestressed CFRP fabric and steel, a prestressed CFRP-steel single-shear specimen was modeled using ABAQUS. The nonlinear bond-slip characteristics of the interface were simulated by utilizing the cohesion unit. The impact of various factors such as the degree of pre-stressing of CFRP fabric, number of layers, pasting width, paste length, and thickness of the adhesive layer on the interface bond performance of the prestressed CFRP-steel single-shear specimens was analyzed. The simulation results indicate that the primary … Read more →

Abstract.With the severe challenge of global climate change and the clear proposal of the "dual carbon" goal, the importance of agricultural carbon sequestration as an important way to mitigate climate change and promote sustainable development has attracted more and more attention from the international community. As an important agricultural province in China, Anhui Province has abundant agricultural resources and huge carbon sink potential, and the willingness of farmers to participate in agricultural carbon sink projects is of great significance to promote the low-carbon development of agriculture … Read more →

Abstract.To address the dual challenges of water scarcity and non-point source pollution in global rice cultivation, this study systematically evaluated the interactive effects of irrigation regimes (continuous flooding, intermittent irrigation, shallow-wet irrigation) and fertilization strategies (conventional fertilization, reduced slow-release fertilizer application). Results showed that the combination of intermittent irrigation with reduced slow-release fertilizer significantly suppressed non-productive tillers (productive tiller rate increased to 74.1%), promoted deep root development (root … Read more →

Abstract.Against the dual backdrop of the global digital wave and the upgrading of enterprise cost management, cost stickiness, as a core feature of dynamic adjustment of enterprise costs, is undergoing technological reconstruction and paradigm shift. Based on adjustment cost theory, agency theory and resource-based view, this article systematically deconstructs the four mechanisms by which digital transformation affects enterprise cost stickiness: technology empowerment reshapes cost structure, data-driven optimization of expectation management, organizational change alleviates agency problems, and … Read more →

Abstract.This thesis explores the pathways for ideological and political education (IPE) in physical education (PE) normal students based on the “curriculum-practice-literacy" framework. Through a review of domestic and international literature, and using questionnaires, interviews, and case analysis,this study empirically investigates the current status of IPE in PE normal students.The research finds that the current IPE faces issues such as insufficient integration of ideological and political elements into the curriculum system, formalized ideological and political education in practical activities, … Read more →
