A mobile agent is a promising area in distributed systems. It is a new technology for computers to communicate. Despite the multiple benefits of the mobile agent, but there are several obstacles to its spread. The mobile agent protection is one of these obstacles. In this paper a new mechanism has been proposed to protect mobile. The mechanism is called Partial-Mobility Mechanism (PMM). The mai...

This thesis considers a nanotechnology approach based on the production of metals pre-treatments and organic coatings (a complete protection system at all) designed from the nanoscale. The final aim is to develop protection systems with improved corrosion protection properties and a low environmental impact. In particular, multifunctional silane hybrid molecules were used to design sol-gel pre-...

Current oxime therapies do not readily cross the blood-brain barrier to reactivate organophosphorus nerve agent-inhibited cholinesterase (ChE) within the CNS. We investigated the ability of monoisonitrosoacetone (MINA), a tertiary oxime, to reactivate ChE inhibited by the nerve agent sarin (GB), cyclosarin (GF), or VX, in peripheral tissues and brain of guinea pigs and determined whether reacti...
