Abstract Biopolyesters, pure and mixed with a compatibilizer, are exposed to UV‐C radiation in the interval 4–32 h. rays act as germicides antibacterial on biomedical materials. The mechanical physical characterization tests have shown how all materials, mixed, undergo photodegradation even if different way. change structural order of polymer, embrittlement, surface wettability water/blood is l...

agent oriented software engineering (aose) is an emerging field in computer science  and  proposes some systematic ideas for multi agent systems analysis, implementation and maintenance. despite the various methodologies introduced in the agent-oriented software engineering, the main challenges are defects in different aspects of methodologies. according to the defects resulted from weaknesses ...

The blending effect of poly maleic anhydride-styrene-methyl methacrylate (MA-St-MMA) terpolymer on non-miscible PVC and Polystyrene was studied depending their thermomechanical properties. Depending the amount synthesized used compatibilizer tensile strength, modulus, properties blends are enhanced. unmodified with small amounts exhibit two-step degradation whereas those containing 6, 8 10 perc...

Polymer nanocomposites with organically modified nanoclay have two different types of interface sites: edges with hydroxyl groups and gallery faces with oxygen atoms. In this study, the polymer-particle interface was strengthened by a coupling agent, aminoalkyldimethoxysilane, which allowed the formation of covalent bonds between silane treated organoclay and maleic anhydride groups of the long...

in this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition petri nets. the mobile agent system contains two mobile agents called dca and una. it sends out agents to update antivirus on client computers in a network. each agent takes on a specified responsibility. first, dca roams through the network and check the last d...
