As an essential component of primitive ecosystems, the ancient tea tree ecosystem possesses irreplaceable value in biodiversity conservation and cultural heritage transmission. However, challenges such as lagging informatization, limited public awareness, and the absence of a unified resource platform hinder its effective protection and management. In response, this study developed a visualization platform for ancient tea tree ecosystems based on the Java technology framework and digital methodologies.........

Smoking is the process of flavouring or preserving food by either cold smoking a lower temperature or by exposing it to smoke from a burning object, typically wood. Smoking is globally acceptable for food products such as fish, meat, chicken, etc., but the traditional method is generally stressful and not hygienic which constantly pose health risks to producers and consumers. Considering this, a low-cost, effective, free-health risk and affordable smoking kiln was developed and evaluated for the use of farmers, households, and small and medium-scale industries for processing fish and other animal products. The machine was fabricated using locally available materials with charcoal as the heat source.........

To meet the requirements of sustainable development of building structures, the application of detachable connectors for steel-concrete composite beams has attracted increasing attention. The high-strength bolt connection point, which is based on the assembly and fastening of threads, can very conveniently realize the assembly connection of the steel beam-flange plate in the composite beam, and has broad prospects for engineering application. This paper analyzes and summarizes the connection characteristics and bearing performance of two different structural forms of connectors, namely the embedded anchorage and the through connection of high-strength bolts, providing a reference for the engineering application of this type of connection.
