This study focuses on the detonation performance and equation of state (EOS) of a low-density composite explosive mixed in a certain proportion of PBX-9502 powder and 502 glue. The theoretical analysis method was used ba...

To investigate the effect of boron nitride (BN) content on the explosion performance of on-site mixed emulsion explosives, the microstructure of BN-containing on-site mixed emulsion explosives were characterized by trans...

Improving the thermal conductivity of polymer-bonded explosives (PBXs) is an important way to enhance the resultant adaptability of PBXs. This study aimed to optimize the secondary thermal conductivity network through th...

The lack of effective diagnostic tools for thermal safety at the early stage hinders the design of efficient explosives to meet the application demands encountering high-temperature cook-off environments. Thus, exploring...

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...

IntroductionPlyometric training (PT) is widely used in team sports, but its outcome-specific effects in female team sport athletes and the influence of key programming variables remain unclear.MethodsThis systematic revi...

A modified low-sensitive explosive composition (LSX) was successfully prepared in the lab. The composition was based on three main explosives: 35 % dinitroanisole (DNAN), 45 % nitrotiazolone (NTO), and 20 % 1,3,5-t...

Abstract The productivity decline of technological wells during in situ leaching (ISL) is primarily associated with clogging of well filters and the near-filter zone, leading to a significant increase in hydraulic resist...

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 ...

To address the short comings of the Lee-Tarver ignition and growth reaction rate equation, which comprises numerous parameters (15) and is difficult to calibrate, semi-periodic trigonometric functions were introduced to ...

Porous ammonium nitrate is frequently used for specific applications due to its porous structure when compared with conventional ammonium nitrate, however, its higher transportation costs increase overall operational exp...

Background and Study Aim. Speed-strength fitness and body dimensions are components of athletic performance in combat sports. The interaction between speed-strength fitness parameters and anthropometric characteristics i...

Abstract The Error Diffusion Learning Algorithm (EDLA) is a learning scheme that performs synaptically local weight updates driven by a single, globally defined error signal. Although originally proposed as an alternativ...

Abstract In Australian open cut coal mines, floor disruption blasting is emerging as a promising technique for mitigating low wall failures by disturbing the continuity of shear planes within weak geological layers. Howe...

During tunnel construction using the drilling and blasting method, layered jointed rock masses often pose engineering challenges such as over- and under-excavation of the crown and working face. The authors addressed the...

Abstract The teak defoliator, Hyblaea puera, is a major pest damaging teak plantations and mangrove ecosystems. The high reproductive and dispersal capacities of this pest often lead to sudden and explosive outbreaks, po...

Purpose: The study aimed to determine the clinical features of the eye trauma and its outcomes in children in Ukraine. Methods: The features of the clinical picture of different types of eye trauma, methods of treatment ...

Abstract Background Basketball is one of the most popular sports. In basketball, the energy demand from several combinations of aerobic and anaerobic sports in which athletes need physical fitness, explosive power, agili...

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 Ice shocks associated with the springtime thermal expansion of ice represent a manifestation of fracture processes in a complex nonlinear medium. In this study, we investigate temporal changes in statistical cha...

Hamstring muscle injuries are among the most common lower-extremity injuries in active individuals. Hamstring injuries follow a consistent pattern with a consistent medical history, which includes a sudden, explosive ty...

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...

Oropouche fever, caused by Oropouche virus (OROV) and transmitted primarily by Culicoides midges, has historically been considered a neglected tropical disease characterized by an acute, self-limiting febrile illness and...
