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...

3D printing is used to produce different permeability structural surfaces, and rock-like samples are poured by moulds. The tests on permeability of rock-like samples with consecutive and filling fractures are carried out...

Preparation of the root canal system is a crucial step in root canal treatment. Endodontically treated teeth differ structurally from healthy, untreated teeth. This can lead to root cracking by creating pressure on the c...

The effect of confinement pressure on fracture toughness may be significant in materials with poor tensile strength, as is the case of most rocks. In fracking wells for hydrocarbon exploitation, rock fracture is induced ...

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...

Large fractures tend to dominate the hydraulic and mechanical properties of fracture networks and, consequently, of fractured rock masses. Hence, their characterization is of primary interest in a variety of applications...

In cases of pulp necrosis, infection products can spread into the periapical tissues, triggering an inflammatory response that stimulates the proliferation of the epithelial cell rests of Malassez. As the epithelial mass...

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...

Abstract The liner of a CNG pressure vessel is manufactured by a DDI (deep drawing and ironing) process for the cylinder part, which is a continuous process that includes a drawing process to reduce the diameter of the b...

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...

Abstract Dehydration reactions in subducted slabs have long been correlated with embrittlement and intermediate‐depth earthquakes. However, the physical process of dehydration embrittlement remains unclear due to the c...

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...

In order to study disaster evolutionary process and failure characteristics of Yonglian tunnel of Ji'an-Lianhua highway under the effect of disturbance, taking F2 fault fracture zone as the research object, a large-scale...

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...

Abstract Graphene has superhigh thermal conductivity up to 5000 W/(m·K), extremely thin thickness, superhigh mechanical strength and nano-lamellar structure with low interlayer shear strength, making it possess great po...

A 70-year-old woman is hospitalized after a fall that resulted in a right femoral neck fracture. Her medical history includes obesity, type 2 diabetes mellitus, hypertension, and chronic kidney disease (CKD). She has smo...
