Introduction: Subsurface investigation is one of the fundamental aspects of exterrestrial exploration. [2] Two general methods of studying the subsurface include in situ instrumentation and remote sample evaluation. This research investigates methods to crush core samples and prepare them for in remote analysis. Specifically, this research develops methods to comminute a core sample or regolith...

• Initial management of nondisplaced type I, type II, and type III odontoid fractures with external cervical immobilization is recommended, recognizing that a decreased rate of union (healing) has been reported with type II odontoid fractures compared with type I or type III odontoid fractures. • Surgical stabilization and fusion of type II and type III odontoid fractures with dens displacement...

Samples of active coke, fresh and spent after cleaning flue gases from communal waste incinerators, were investigated. The outer layers of both coke particles were separately removed by comminution in a spouted bed. The samples of both active cokes were analysed by means of densities, mercury porosimetry, and adsorption technique. Remaining cores were examined to determine the degree of consump...
