issue 64, 1 st quarter 2012 / JFQ 115 T hink about the current laser designation capability used to direct precision-guided munitions (PGMs) to destroy an enemy target. Now, imagine replacing that laser designator with a high-energy laser (HEL) weapon that emits enough thermal energy to directly render a target ineffective without using a conventional munition. That HEL weapon will affect targe...

We formulate and analyze a spatial queueing model concerning a terrorist who is attempting to drive a nuclear or radiological weapon toward a target in a city center. In our model, imperfect radiation sensors form a circular wall around the periphery of the city, and vehicles setting off sensor alarms (representing a terrorist or a nuisance alarm) arrive randomly at the perimeter of a circle (r...

All the evidences point out to the fact that the incidence, mortality and number of persons living with cancer are on the rise and, thus, this will impose a significant burden on health care resources. The considerable number of deaths from cancer necessitates the need to developing novel alternative cures that are efficient, safe, cheap and easy to use. In the search for new therapies for tumo...

The concept that weapon choice and use may play a valuable role in differentiating between offenders is one that has not been well explored in current criminological or psychological thinking. The key aim of the current paper is to discuss the role of weapon choice and use in the application of offender profiling.

The horrific nature of murder using different types of weapons has been an important focal point of many criminological studies. Weapons that are used in murders seem to play dominant roles in murder investigations as they may provide information leading to arrest.

INTERTROCHANTERIC FRACTURES Approximately 50% of intertrochanteric fractures are stable and have minimal or no posteromedial comminution. The remaining 50% are unstable and have posteromedial instability and little resistance to varus deformity.1,4,5 Older rigid devices led to cutout or penetration of the nail as the fracture impacted. In the late 1960s, sliding devices were developed to allow ...
