BACKGROUND Blast-related traumatic brain injury (TBI) has been a significant cause of injury in the military operations of Iraq and Afghanistan, affecting as many as 10-20% of returning veterans. However, how blast waves affect the brain is poorly understood. To understand their effects, we analyzed the brains of rats exposed to single or multiple (three) 74.5 kPa blast exposures, conditions th...

Contingency operations are by their nature unpredictable and high-risk, with undeveloped logistical support, and medical provision is no exception. Can the contingency experiences of the last three decades help to predict the type of casualties that may be seen in future contingency operations? By reviewing published casualty statistics available from Operations CORPORATE, TELIC 1 and HERRICK 4...

By evaluation of the blasting results, a proper blast pattern can be presented. It is, therefore, essential to employ a reliable method to evaluate blastings for the effective control and optimization of the main cycle operations. This paper aims to propose a criterion for evaluating the blasting results such as the fragmentation, muckpile condition, back-break, and fly rock, and to make a poss...

Ground vibrations caused by blasting are undesirable results in the mining industry and can cause serious damage to the nearby buildings and facilities; therefore, controlling such vibrations has an important role in reducing the environmental damaging effects. Controlling vibration caused by blasting can be achieved once peak particle velocity (PPV) is predicted. In this paper, the values of P...

explosion and fire on an offshore rig can lead to its minor or complete damage and sinking which means the loss of life or environmental pollution. hence the use of techniques such as blast wall is crucial to reduce the detrimental effects. these blast walls are designed for explosion wave of length between 0.1 to 1 of load mainly to protect the personnel and critical sections. in this research...

Blast-induced traumatic brain injury has dramatically increased in combat troops in today's military operations. We previously reported that antioxidant treatment can provide protection to the peripheral auditory end organ, the cochlea. In the present study, we examined biomarker expression in the brains of rats at different time points (3 hours to 21 days) after three successive 14 psi blast o...
