INTRODUCTION On 7 July 2005 four suicide bombings occurred on the London transport systems. In some of the injured survivors, bone fragments were embedded as biological foreign bodies. The aim of this study was to revisit those individuals who had sustained human projectile implantation injuries as a result of the bomb blasts at all scenes, review the process of body parts mapping and DNA ident...

This work presents an experimental design for studying low-velocity collisions into granular surfaces in low-gravity. In the experiment apparatus, reduced-gravity is simulated by releasing a free-falling projectile into a surface container with a downward acceleration less than that of Earth's gravity. The acceleration of the surface is controlled through the use of an Atwood machine, or a syst...

Two weeks after Joseph Biden took office as President, the U.S. and Russia extended New Strategic Arms Reduction Treaty for five years. This landmark arms control treaty limits number of strategic offensive weapons each country can have. A ‘window opportunity’ a new stage stability discussions on has opened. competition between world’s most powerful countries, escalating global regional threats...

The formation of longitudinally elongated composite systems is a general feature of central heavy-ion collisions [1]. It can be the result of a transparency, i.e. of an incomplete stopping of the incoming projectile by the target, as, e.g., observed by the FOPI collaboration for Zr+Ru collisions at 400 A.MeV [2]. Here, we report new data, measured with INDRA at GSI, for the Xe+Sn collisions at ...

The decay of excited 0 projectiles into the four alpha particle exit channel has been investigated. The projectiles, with bombarding energies of E/A = 25 MeV, were excited through peripheral interactions with ' Tb target nuclei. A 4' counter was used to detect both the projectile alpha particles and the light charged particles evaporated from the target nucleus. Criteria for selecting true 0~4o...
