Construction and Evaluation of a Modular Anthropomorphic Phantom of the Skull with an Exchangeable Specimen Jar to Optimize the Radiological Examination of Temporal Bone Pathology

Received: 26 March 2024;  Published: 25 July 2024;  doi: 10.21926/rpm.2403018

Abstract

To develop a modular anthropomorphic phantom to evaluate the performance of radiological techniques for detecting pathologies in the temporal bone region. A phantom was constructed using a human skull, temporal bone specimen, and 3D-printed contour of a human skull. The human skull was embedded in t [...]

Development of the Stochastic Interpretation of Quantum Mechanics by E. Nelson. Derivation of the Schrödinger-Euler-Poisson Equations

Received: 10 November 2023;  Published: 26 June 2024;  doi: 10.21926/rpm.2402014

Abstract

The article aims to develop the stochastic interpretation of quantum mechanics by E. Nelson based on balancing the intra-systemic contradiction (i.e., antisymmetry) between “order” and “chaos”. For the set task, it is proposed to combine two mutually opposite system-forming principles: “ [...]

The Effect of Rake Angle and Cutting Edge Radius on the Orthogonal Cutting Process of Ti6Al4V Alloy

Received: 23 February 2024;  Published: 18 June 2024;  doi: 10.21926/rpm.2402013

Abstract

This paper investigates the effect of rake angle, α, cutting edge radius, r, and feed rate, f, on the cutting force and cutting zone temperature during orthogonal dry cutting of Ti6Al4V. A numerical model representative of the 2D orthogonal cutting process is developed using ABAQUS/Expli [...]

Spin Entanglement – A Unifying Principle for Superconductors and Molecular Bonding

Received: 20 December 2023;  Published: 03 June 2024;  doi: 10.21926/rpm.2402012

Abstract

The spin-statistics theorem is generalized to include quantum entanglement. Specifically, within the context of spin entanglement, we prove that isotropically spin-correlated (ISC) states must occur in pairs. This pairing process can be composed of parallel or anti-parallel states. Conse [...]

Whisker Bond: From Findings to Concept in Refractories

Received: 12 January 2024;  Published: 12 April 2024;  doi: 10.21926/rpm.2402010

Abstract

Ceramic bonds are conventionally formed during the burning of refractory bricks and by using pre-fabricated blocks or monolithic lining, which is characterized as the coalescence of the particles by liquid sintering. However, the whisker bond was discove [...]
