Abstract.Using Python language to import Voronoi diagrams into ABAQUS, a two-dimensional microscopic model of vibration cutting of 45 steel is established, and based on this model, the stress changes of grains and grain boundary units on the cutting path are analyzed. The results show that in ultrasonic vibration cutting, the direction of normal stress and shear stress in the grain fracture unit will reverse, and the energy threshold will be reached during multiple impact processes, resulting in failure and deletion; During the impact process, grain boundaries are more prone to advanced failure under … Read more →

Abstract.With the continuous increase in urbanization, the annual output of construction waste has consistently grown at a high speed. Based on extensive research and comparative analysis of relevant literature, this paper summarizes recent reinforcement methods for recycled concrete aggregate. The primary obstacle to utilizing construction waste resources is the significant amount of old cement mortar attached to the surface of recycled aggregate. This not only increases water absorption rate but also creates numerous weak interface transition zones in recycled concrete, greatly impacting its … Read more →

Abstract.The "the Belt and Road" is a win-win cooperation road to promote common development and achieve common prosperity, and a peaceful friendship road to enhance understanding and trust and strengthen all-round exchanges. This article first explores the current development status of RMB nationalization and analyzes the current process of RMB internationalization from multiple perspectives. Then, it analyzes the impact of "the Belt and Road" initiative on RMB internationalization from both opportunities and challenges. Finally, it proposes suggestions and specific implementation paths for RMB … Read more →

Abstract.This study screened fish derived spoilage bacteria as the research object, and a development approach was used to determine the inhibitory effect of rose polyphenols on the secretion of the quorum sensing (QS) signal molecule N-acyl homoserine lactone (AHLs) by fish spoilage bacteria. The effect of rose QS inhibitors applied to fish preservation coatings on the putrefaction of spoilage bacteria was studied by measuring the changes in texture, pH, and thiobarbituric acid reactive substances (TBARS) during the storage process of fish. The findings demonstrated that the dominant strain causing … Read more →

Abstract.On November 16, 2016, the Oxford Dictionary first defined the term "post truth" as the "annual vocabulary" of 2016, which refers to emotions and personal beliefs being more influential than objective facts in influencing public opinion. Since then, the "post truth" has also been increasingly concerned and discussed by the academic community. This article takes the "post truth era" as the theoretical background to explore the reasons and manifestations of the emotional shift in online public opinion in universities, and proposes corresponding response strategies.
