ESTIMATION OF IGNITION PRESSURE IN AMMUNITION

Estimation of Ignition Pressure in Ammunition

This paper presents the experimental Tips estimation of the ignition pressure value produced by a primer in small arms ammunition.Investigations were performed using a chamber of the capacity equal to the capacity of the 12.7 mm ammunition case.The inner volume of the chamber was adjusted to the free volume in the cartridge by inserting a sleeve or

Self-reverting vortices in chiral active matter

Abstract There is currently a strong interest in the collective behavior of chiral Sweater Dresses active particles that can propel and rotate themselves.In the presence of alignment interactions for many chiral particles, chiral self-propulsion can induce vortex patterns in the velocity fields.However, these emerging patterns are non-permanent, an

Spontaneous Spine Fracture in Patient with Ankylosing Spondylitis under Spinal Anesthesia: A Case Report and Review of the Literature

Factures in ankylosing spondylitis (AS) patients tend to occur due to the absence of motion between vertebrae, poor bone quality, and a long lever arm that generates extension force.However, most patients have a history of at least minor trauma.The aim of this report was that a vertebral fracture in a patient with AS can be caused not only by minor
