objective(s): the aim of this work was to prepare and characterize magnetic nanoparticles (mnps) as theranostic system to act simultaneously as drug carrier and mri contrast agent. chitosan-coated mnps (cmnps) were prepared and loaded with silymarin. silymarin-loaded cmnps were characterized with various techniques and their potential as mri contrast agent was also evaluated. materials and meth...

agents, in a multi agent system, communicate with each other through the process of exchanging messages which is called dialogue. multi agent organization is generally used to optimize agents’ communications. holonic organization demonstrates a self-similar recursive and hierarchical structure in which each holon may include some other holons. in a holonic system, lateral communication occurs b...
