Unfortunately, the absence of radial or concentric fracture lines prevents Bullet Impacts. However, as the velocity of penetrating projectile decreases, the irregularities of shape of hole, and its surrounding cracks increases so at that point the hole shape may not determine the direction of impact. These include scanning electron microscopy-x-ray spectroscopy, x-ray fluorescence spectroscopy, mass spectrometry, optical emission spectroscopy and inductively coupled plasma methods.[4]. 8z5Zm,M6ZglcI]S8f[P0$^^S a 0C+_|}*Rd 1"qN As the first fractures form on the surface opposite that of the penetrating force, and these fractures develop into radial lines. A symmetrical hole could be formed by a projectile hitting the glass at a 90 degree angle while elliptical holes can be formed by projectiles hitting a pane of glass from the left or right side.[5]. Kabadiwallas collect waste like plastic, glass waste and old newspapers and pass it on to the recycling units. When describing a fracture, the first thing to mention is what type of fracture it is. In these cases, trace evidence lifters, forensic vacuums or tweezers can aid in the collection of the glass evidence. The 3R rule states " radial fractures make right angles to the rear ." By examining the radial fractures and the direction in which they form a right angle, the rear side of the pane of glass (opposite the side the force was applied) can be determined. Fracture and stress lines can be used to guide a mechanical fit between two pieces of glass. Crohn's Disease Weekly Meal Plan, [1] In assaults, broken glass bottles may be found and analyzed in addition to glass fragments that may remain on clothing.
