Abstract When the upper chord beam of the beam-string structure (BSS) is made of concrete-filled steel tube (CFST), its overall stiffness will change greatly with the construction of concrete placement, which will have an impact on the design of the tensioning plans and selection of control measures for the BSS. In order to accurately obtain the bending stiffness of CFST beam and clarify its impact on the mechanical properties of composite BSS during construction, the influence of some factors such as height-width ratio, wall thickness of steel tube, elasticity modulus of concrete, and friction coefficient on More >

Abstract L’annonce d’une maladie cancéreuse éveille ou renforce pour certains les représentations liées au pouvoir du psychisme sur le corps. L’investigation du champ des théories psychosomatiques convoque les croyances en une psyché garante de la bonne santé somatique. Une confusion dans l’appréhension des concepts liées aux facteurs psychiques comme responsable du bon fonctionnement du corps a, selon nous, des effets dans l’après-coup pour les femmes atteintes d’un cancer du sein. L’étude est menée auprès de six femmes atteintes d’un cancer du sein portant sur l’influence des croyances et des représentations de la maladie cancéreuse du sein.… More >

Abstract Biological membranes play crucial roles in cellular functions, serving as dynamic interfaces that regulate the passage of molecules and signals between the cell and its environment. Understanding how these membranes respond to environmental stimuli is paramount in elucidating cellular adaptation and survival mechanisms. In this talk, we will present our recent studies on the structural and mechanical changes of biological membranes in response to two different environmental factors, including the presence of reactive oxygen species (ROS) and dehydration. Through systematic molecular dynamics simulations, we have revealed a dynamic interplay between membrane components, membrane mechanics and… More >

Abstract Background: The demanding nature of nursing, characterized by long hours, high-stress environments, and substantial workloads, can significantly impact nurses’ mental health. However, there are limited studies that assessed the influence of workplace environment on nursing mental health based on both quantitative and qualitative approaches. Methods: This study aims to comprehensively investigate the multidimensional relationship between the workplace environment and nurses’ well-being. This cross-sectional study was based on a sample of 3256 nurses from various healthcare settings in Shandong province, China (2022), who participated in the quantitative phase. For the qualitative phase, a subsample of participants… More >

Abstract Hydrogen has the potential to be the clean energy solution to achieve the sustainable development goals (SDGs). However, from preparation to utilization, the hydrogen embrittlement can not be neglected. Hydrogen embrittlement occurs as a result of hydrogen affecting dislocations motion and cracks opening. Dislocation motion in hydrogen environment has not been clarified although several mechanisms have been proposed, including the hydrogen enhanced decohesion (HEDE), the hydrogen enhanced macroscopic ductility (HEMP), the hydrogen enhanced local plastic model (HELP), etc. It is essential to comprehend the underlying hydrogen-dislocation interactions that cause embrittlement. Also, dynamics of dislocation motion… More >

Abstract The plastic deformation assisted method plays a positive role in regulating the microstructure and mechanical properties of metal components in additive manufacturing. In this work, the effect of hammer forging force on the microstructure and mechanical properties of 316L stainless steel additive components were investigated by using synchronous-hammer-forging-assisted laser directed energy deposition method. The results show that when the hammer forging force is greater than 40 N, the grain refinement effect is obvious, the grain size decreases by more than 60 %, and the maximum strength of the polar diagram decreases by more than 75 More >

Abstract Invar alloy is widely used in the field of aeronautical composite die manufacturing because it has a very low coefficient of thermal expansion, which is like that of composite material. The laser-MIG (Metal-Inert Gas) hybrid welding was developed to join 10 mm thick Invar alloy plates using Invar M93 filling wire. High speed camera equipment was used to observe plasma dynamic processes. Three-dimensional finite element models of laser-MIG hybrid welding process were established to solve the flow field of the molten pool by two leading modes. Elaborated on the flow behavior of the molten pool More >

Abstract Background: Online game addiction has become a serious global public health problem among adolescents. However, its influencing factors and mediating mechanisms remain ambiguous. Methods: The present study adopted stratified random sampling to collect 6146 junior high school student samples in mainland China. We used regression analysis, and Bootstrap mediation test through SPSS 26.0 and AMOS 24.0 to reveal the tendency of students’ online game addiction with different background characteristics and whether autonomy support from parents and teachers can effectively reduce online game addiction. Results: The results showed that parental (β = −0.112, p < 0.001) and… More >

Abstract Heat engines based on reciprocating machines remain in demand as energy converters in a variety of industries around the world. The aim of the study was to evaluate the gas-dynamic, consumable and heat exchange characteristics of non-stationary air flows in a supply system with transverse profiling of valve channels based on experimental studies. Valve channels with cross sections in the form of a circle, square and triangle were used to control the consumable and heat exchange characteristics of the flows in the supply system of the reciprocating-engine model.
