AI Article Synopsis

  • The study aims to explore how a firearm can create a negative angle of reflection after bouncing off a surface, based on experimental data.
  • Ballistic experiments revealed that while firearms typically reflect at a positive or zero angle, it's possible for ricocheted buckshot to form a negative reflection angle under certain conditions.
  • The findings, termed the ballistic "Gusentsov phenomenon," have broad implications for enhancing understanding in ballistics and can be applied in various fields including science, law enforcement, and education.

Article Abstract

The purpose of the study is to establish the possibility, determine the conditions and parameters for the formation of a negative angle of reflection of a firearm after a ricochet from the surface of an obstacle based on the results of our own experimental studies. Expert and law enforcement practice shows that after a shot, firearms, both before interaction with an obstacle and after a ricochet, move in space in the same plane with respect to the surface of the obstacle, forming a reflection angle with a positive or zero degree value. As a result of ballistic experiments, the possibility of forming a negative angle of reflection by ricocheted buckshot was established, the conditions and parameters for the occurrence of this pattern were determined. The identified ballistic «Gusentsov phenomenon» has an important interdisciplinary scientific and practical significance for further expanding knowledge and understanding of external and internal ballistics and can be successfully used in scientific, practical, forensic and educational activities.

The phenomenon of snaking of vehicles can be caused by many factors. It results from the loss of the vehicle's straight-line direction of motion, which is intended by the driver. In this situation, for single-mass vehicles (like automobiles), special systems (braking) are activated, aiming to return the vehicle to the direction intended by the driver.

Objective: Malalignment following cervical spine deformity (CSD) surgery can negatively impact outcomes and increase complications. Despite the growing ability to plan alignment, it remains unclear whether preoperative goals are achieved with surgery. The objective of this study was to assess how good surgeons are at achieving their preoperative goal alignment following CSD surgery.

Human dentin performs its function throughout life, even though it is not remodeled like bone. Therefore, dentin must have extreme durability against daily repetitive loading. Elucidating its durability requires a comprehensive understanding of its shape, structure, and anisotropy at various levels of its structure.

An apparent contact angle is formed when a droplet is deposited on a solid substrate. Young's law has been employed to describe the equilibrium contact angle. Often in experiments, the equilibrium contact angle deviates from Young's law and depends on the volume of the droplet, known as the line tension effect.

The crystal structures and hyperfine magnetic parameters of EuFe(BO) and mixed EuLaFe(BO) were studied over a wide temperature range in order to analyze correlations of the structural and magnetic features and the phase transitions in multiferroic compounds of the rare-earth iron borate family. The chemical compositions of the crystals are reported from X-ray fluorescence analysis. The crystal structures of EuFe(BO) and EuLaFe(BO) were determined using single-crystal X-ray diffraction in the temperature range 25-500 K.
