  • accidental fatal craniocerebral injury caused by broken chain of sawing tool
    Forensic Science International, 2018
    Co-Authors: Jozef Sidlo, Henrieta Sidlova
    Abstract:

    The case of an accidental fatal penetrating craniocerebral injury to a 26-year-old man at work when cutting wood is reported. There was used an Angle Grinder with an accessory for cutting similar to a chainsaw. The injury was caused by a fragment of the broken chain. The chain fragment broke through the facial part of the head to the left and penetrated the brain in the region of the left parietal bone of the cranial vault. The immediate cause of death was a failure of the central nervous system (brain death). The toxicological analysis of biological materials was negative. The death occurred as a result of a triple violation of safety precautions. The presented case is extremely rare in terms of fatal injuries caused by power tools for sawing having been published in the forensic literature.

  • mathematical modelling and optimization of single phase high speed flux reversal motor
    International Conference on Electrical Machines, 2018
    Co-Authors: Vladimir Prakht, Vladimir Dmitrievskii, Vadim Kazakbaev, Sergey Sarapulov
    Abstract:

    The paper considers mathematical modeling and optimization of the design of a single-phase high-speed flux reversal motor for an Angle Grinder. The optimization criterion and the selection of the optimization algorithm are described. The optimization target parameter is the motor efficiency when operating at different loads while limiting the mass of permanent magnets that can be demagnetized. Calculations show that after optimization, it was possible to significantly increase the motor efficiency and reduce the rotor diameter.

  • angular Grinder with new flux reversal motor
    International Conference on Electrical Machines and Systems, 2015
    Co-Authors: Vladimir Dmitrievskii, Vladimir Prakht, Vladimir Klimarev, Andrey Pozdeev, Alexander Mikhalitsyn
    Abstract:

    In this paper a new Flux Reversal machine is described. An Angle Grinder development with this machine is considered. The experimental results of the Angle Grinder investigation are presented. A FRM model based on a set of magnetostatic boundary problem is proposed. In postprocessing the model allows us to estimate the various types of losses. The FRM simulation using the model is presented.

  • Penetrating head injury from Angle Grinder: A cautionary tale
    Medknow Publications, 1
    Co-Authors: Senthilkumaran S, Balamurgan N, Arthanari K, Thirumalaikolundusubramanian P
    Abstract:

    Penetrating cranial injury is a potentially life-threatening condition. Injuries resulting from the use of Angle Grinders are numerous and cause high-velocity penetrating cranial injuries. We present a series of two penetrating head injuries associated with improper use of Angle Grinder, which resulted in shattering of disc into high velocity missiles with reference to management and prevention. One of those hit on the forehead of the operator and the other on the occipital region of the co-worker at a distance of five meters. The pathophysiological consequence of penetrating head injuries depends on the kinetic energy and trajectory of the object. In the nearby healthcare center the impacted broken disc was removed without realising the consequences and the wound was packed. As the conscious level declined in both, they were referred. CT brain revealed fracture in skull and changes in the brain in both. Expeditious removal of the penetrating foreign body and focal debridement of the scalp, skull, dura, and involved parenchyma and Watertight dural closure were carried out. The most important thing is not to remove the impacted foreign body at the site of accident. Craniectomy around the foreign body, debridement and removal of foreign body without zigzag motion are needed. Removal should be done following original direction of projectile injury. The neurological sequelae following the non missile penetrating head injuries are determined by the severity and location of initial injury as well as the rapidity of the exploration and fastidious debridement
