Mobile agents are autonomous objects that can migrate from one host to another within a computer network. Concurrent execution of multiple mobile agents requires a concurrency control for data consistency. Some mobile agent applications, such as information retrieval, do not need a concurrency control, but most applications, for example workflow and electronic commerce, require such a control o...

Not only are the quantities of emerging precision cleaning agents, equipment, and processes staggering, but assessing their level of performance relative to previous approaches presents even greater challenges. As en vironmentally harmful cleaning solvents are phased out and replaced, the quest for implementing alternative technologies raises numerous questions: l What alternative cleaning agen...

ethosomes are a novel and alternative drug delivery systems and currently the focus of many research activities. ethosomes are soft, flexible vesicles that are composed mainly of phospholipids, ethanol and water. ethosomes can provide better skin permeation than liposomes and deliver enhanced amounts of both small and large therapeutic agents through skin and targeting to deeper skin layers for...

The highly substituted pyridine derivatives are found to exhibit diverse pharmacological activities. They are also emerged as potential medicinal leads in developing therapeutic agents for the treatment of various diseases. In this work, a series of 2-amino-3,5-dicarbonitrile-6-thio-pyridine derivatives have been synthesized at room temperature via one-pot, multi-component reaction of various a...

the aim of this work was to study the ability of two biodegradable chelating agents, nitrilotriaceticacid (nta) and ethylenediiminopropanedioic acid (eddm) to complex metals, in the treatment of the pulp,prior to a totally chlorine free (tcf) bleaching process, and compare with the ethylenediaminetetraacetic acid(edta) performance. firstly, speciation efficiency index (sei) was calculated by co...

When interacting autonomous agents operate in open domains that contain novel objects, the agents may not be able to refer to the objects by using preassigned names. As an alternative, the agents might use descriptions. When agents refer to domain objects by using descriptions, referent misidentifications will occur. This paper models recovery from referent misidentifications in systems of such...
