  • GunShot wounds: Radiology and wound ballistics
    Emergency Radiology, 1995
    Co-Authors: Jeremy J. Hollerman, Martin L. Fackler
    Abstract:

    Bullets of equal wounding potential may produce wounds of very different severity. Wounding is an interaction between the missile and the tissue. When attempting to predict wound severity, focusing on missile velocity while forgetting either the properties of the tissue wounded or the missile’s mass and construction leads to very poor predictions. Fortunately, all the poor predictions commonly made are of little consequence as it is the condition of the patient, not the type of firearm or missile used, that determines the treatment needed. Tissue crush and tissue stretch by displacement (temporary cavitation) are the only wounding mechanisms of missiles. Tissue stretch is tolerated very differently by different tissues. Missiles can embolize. Missile type, direction of fire, and order of Shots can sometimes be assessed radiologically. Lead bullets or fragements in joints cause lead synovitis, mechanical arthritis, and sometimes lead poisoning. When possible, they should be removed. For Shotgun wounds, Steel Shot may be ferromagnetic and is important to recognize prior to magnetic resonance imaging. Steel Shot stays round and does not deform like lead Shot. The "billiard ball effect" may compromise assessment of range unless correlated with skin physical examination.

  • Effects of embedded tungsten-bismuth-tin Shot and Steel Shot on mallards (Anas platyrhynchos).
    Journal of Wildlife Diseases, 1996
    Co-Authors: Brita J. Kraabel, Michael W. Miller, David M. Getzy, James K. Ringelman
    Abstract:

    We assessed the potential for embedded Steel and tungsten-bismuth-tin (TBT) Shot to adversely affect health of mallards (Anas platyrhynchos). Ducks were implanted with three number four Steel (n = 19) or TBT (n = 20) Shot pellets in their pectoral muscles. None of seven hematology parameters measured differed in response to treatment (P ≥ 0.17). At necropsy 1, 2, 4, and 8 wk posttreatment, we observed only localized tissue reactions to embedded Steel or TBT Shot. Reactions differed grossly: after wk 1, embedded Steel Shot were enveloped in 0.5 to 2 mm grayish capsules, whereas TBT Shot were surrounded by thinner (

  • Effects of ingested tungsten-bismuth-tin Shot on captive mallards
    Journal of Wildlife Management, 1993
    Co-Authors: James K. Ringelman, Michael W. Miller, William F. Andelt
    Abstract:

    Steel Shot is required for waterfowl hunting in the United States, but hunter dissatisfaction with Steel's perceived ballistic performance has reduced compliance with Steel Shot laws, contributed to the loss of waterfowl hunters nationwide, and renewed interest in an alternative non-toxic Shot with ballistic qualities similar to lead Shot. We evaluated the acute toxicity of an alternative Shot by orally dosing 20 8-week-old game farm mallards (Arras platyrhyrrchos) with 12-17 pellets (x = 1.03 g) composed of tungsten, bismuth, and tin (TBT). Ducks were monitored for 32 days for evidence of intoxication. Eroded Shot evident in radiographs taken 11 days post-dosing indicated acute exposure to the constituent metals, but no dosed or undosed birds died during the trial

  • Brief Discussion on Influence of Shot Blasting Process on Surface Quality of Stainless Steel Sheet
    Tianjin Metallurgy, 2014
    Co-Authors: Zhang Zhi-qian
    Abstract:

    The author analyzes the influence of the production process of different rotation speeds and Steel Shot sizes of Shot blasting machine on the surface roughness of stainless Steel sheet.Actual production experience is summarized and the Shot blasting process of low impeller rotation speed is taken.Through optimizing the charging style of Shot blasting,the size stability of Steel Shot in Shot blasting machine is ensured and the size fluctuation of Steel Shot is reduced,which reduces the surface roughness of stainless Steel sheet effectively and guarantees the treatment effect.
