Introduction Early open fracture management aims to minimise the risk of complications. For the most severe open fracture wounds, multiple irrigation and debridement surgeries are required to overcome severe wound contam...

This study proposes a deep-hole directional blasting technology based on polymer energy charge packages for roof cutting and pressure relief as a solution to difficult roadway support and poor stability of coal pillars d...

Abstract Earthquakes are a major geohazard worldwide, and understanding their triggering mechanisms remains a key research objective. Currently, many noteworthy studies have proposed mechanisms to explain the triggering ...

Abstract‌ Objective This finite element analysis compared the biomechanical performance of two surgical approaches for Neer Type II distal clavicle fractures: isolated locking plate fixation versus locking plate fixati...

Background The application of intraoperative tourniquets is a fundamental component of distal radius fracture surgery, yet it carries a risk of significant complications. The British Orthopaedic Association (BOA) has pub...

BackgroundIn practical engineering, the waterproof coal pillar usually suffers from different degrees of dynamic load from the overlying strata, and its internal water distribution is non-uniform. Although the traditiona...

This study investigates the tensile mechanical properties of gray sandstone under dynamic impact. Drawing on the one-dimensional stress wave theory, we conducted a one-dimensional spallation experiment using a 50 mm diam...

Abstract Thick-hard roof fracturing presents a significant challenge for disaster prevention in longwall mining. This study investigates the 15,311 south working face and develops a mechanical model to analyze energy rel...

Objective and MethodTo achieve rapid coalbed methane (CBM) extraction from broken-soft coal seams using surface horizontal wells, this study proposed a volume fracturing technology for coal seam roof using horizontal wel...

To meet the requirements of precision and high-performance diffusion bonding for titanium alloy structures, pure graphite was used as the position limitation block. Diffusion bonding tests of TA15 titanium alloy samples ...

To enhance the total output energy and power of energetic materials, plasma that generated by electrically exploded metal wires was employed to initiate the detonation of energetic materials, thereby achieving the couple...

To investigate the influence of cracks and gaps on the reaction evolution characteristics of aluminum-containing DNAN-based explosives after the formation of mechanical induced hotspots, explosive charge samples with dif...

Abstract Yunkai area is located in the southwest of South China Block and is characterized by widespread granite distribution, dense hot spring occurrences, and well-developed deep faults, indicating significant geotherm...

Compressed air injuries to the globe are rare and typically associated with orbital fractures or a visible entry wound. The authors report the case of a 16-year-old male with Marfan syndrome who developed orbital emphyse...

Powder compaction is the most widely used technology to fabricate polymer bonded explosives (PBX), and its parameters significantly influence the structures and mechanical properties of the final products. By conducting ...
