This study aims to contribute to the estimation of power consumption in a disintegration process in disc crushers (fixed and mobile). The study covers the dynamic analysis of forces acting on the particles and the mobile disc. A detailed analysis of the resultant force on the particles was performed. Finally, the consumed power is calculated with the forces acting on the mobile disc. The calculated power is a key aspect in the design of disc crusher machines.

The classic forms of disc crusher disintegration simulations are faced using methods that associate their analysis to the stochastic nature of the process. This paper introduces a method that can solve the disc crusher disintegration simulation with a partially deterministic manner. The paper presents the result of the thrust force and the consumed power of disc crushers which is estimated by a static analysis of forces that interact within the discs (fixed and mobile). This methodology uses the calculation of forces and directions involved in the process of particle fragmentation. The fragmented material is characterized. The fragmentation process is simulated with the help of the computer programme to finally estimate the consumed power. For comparison purposes, two types of disc crushers are designed to determine the capability of the method after assessing the results.

“The birth of conjoined twins is one of the rarest neonatal conditions worldwide, with an incidence of 1 in 100,000 live births. Twins joined by the pelvis, known as ischiopagus, represent 6–11% of all conjoined twins. This clinical condition increases the degree of complexity in separation surgeries. Each case poses unique anatomical challenges, and clinical outcomes may vary according to the health facility where the infants are born or can access. This case report describes a successful separation surgery of ischiopagus conjoined twins in Peru. 3D printing and neurophysiological monitoring were used for surgical planning and intervention, allowing a fullscale anatomical model and preserving the mobility of the lower limbs of conjoined twins after surgery. This article demonstrates that established procedures and novel technologies can be valuable platforms for preoperative plannin...
