This work reports the computational analysis of the physicochemical, detonation, blast peak over pressure, blast impulse and TNT equivalence parameters of some of the Improvised Energetic Materials (IEMs) such as ammonium nitrate, urea nitrate, C4, hexamethylene triperoxide diamine (HMTD) and triacetone triperoxide (TATP), which are used in bombing incidents all over the world in the form of Vehicle-Borne Improvised Explosive Devices (VBIEDs) or Person-Borne Improvised Explosive Devices (PBIEDs). The blast impulse, peak over pressure, TNT equivalence and detonation parameters reported in this manuscript will be useful to assess the threat quotient caused by these IEMs, of great help for the energetic materials researchers, technologists and scientists to undertake further research work in the field and for the security agencies to understand the severity of the damage during explosion This paper also accounts for the available detection technologies to fabricate an explosive detection device for its effective identification and detection.

IntroductionThe Chinese Role 2 Hospital (CHN-Role 2H) Medical Treatment Facility (MTF) was founded in July 2013 as part of the Chinese commitment to Multidimensional Integrated Stabilization Mission in Mali (MINUSMA). It provides medical care for approximately 5200 personnel of the whole Sector East of MINUSMA including UN military personnel, UN police and UN civilian staff. The aim of this study was to determine the orthopaedic surgical activity over a 4-year period to facilitate the training of future Chinese military surgical teams.Materials and methodsSurgical records of all patients operated on at the CHN-Role 2H between 28 March 2014 to 28 March 2018 were identified, and all orthopaedic activity were analysed.ResultsDuring this period, 1190 patients underwent 2024 surgical procedures. Orthopaedic procedures represented 961/2024 (47.5%) of all the procedures. Battle injury (BI) represented 43% of patients. Improvised explosive devices (IEDs) were responsible for 15.8 % casualties. Fractures (49%) and soft tissue injures (43%) were the most common injuries, with 61% of the fractures being open. Damage control surgery including debridement (23.52%) and external fixation (17.90%) were the most frequently performed interventions.ConclusionOrthopaedic surgery is the most frequently performed surgery in the CHN-Role 2H in Mali. The complexity and severity of injuries demonstrate the urgent need for tailored training and extended skill sets for deploying military orthopaedic surgeons.
