Abstract.Thin-walled parts are widely used in various fields of industrial production, but their inherent characteristics, such as low stiffness and susceptibility to deformation, make them prone to various defects during use. Thin-walled covering parts, which serve as thin shells or covers to protect other components, are extensively utilized in aerospace, automotive, and shipbuilding industries. The condition of these parts is directly related to the structural integrity, performance stability, and operational safety of the associated components and equipment. Due to their direct exposure to external … Read more →

Abstract.The development of low-carbon technology in urban construction is rapid, whereas in rural and other economically underdeveloped areas, the development of low-carbon buildings is relatively lagging behind. Achieving the low-carbon retrofitting of rural buildings is crucial for reaching the "dual carbon" strategic goals. This study conducted an in-depth investigation into the current situation, energy consumption levels, and factors affecting carbon emissions of rural buildings in Nanyang City. Using DeST simulation software, the energy consumption of a rural building in Wolong District of … Read more →

Abstract.As a crop of critical global significance, maize requires substantial water throughout its growth cycle. However, with climate change intensifying and water resources becoming increasingly scarce, drought has emerged as a primary limitation on maize productivity. By delving into the molecular underpinnings of drought resistance in maize, researchers have pinpointed an array of drought-resilience genes, transcriptional regulators, and signal transduction pathways, offering a valuable genetic reservoir for enhancing maize’s drought resistance. Advanced molecular tools, including genome editing … Read more →
