this paper describes how multi-agent system technology can be used as the underpinning platform for voltage control in power systems. in this study, some facts (flexible ac transmission systems) devices are properly designed to coordinate their decisions and actions in order to provide a coordinated secondary voltage control mechanism based on multi-agent theory. each device here is modeled as ...

two simple, accurate and precise methods for simultaneous estimation of esomeprazole and itopride in bulk drug and tablet dosage form have been described. method-a employs formation and solving of simultaneous equation using 231 and 370 nm as two analytical wavelengths. method -b is absorption ratio method, which uses 308 and 331 nm as two analytical wavelengths.beer’s law was obeyed in the con...

background: streptokinase is a potent activator of plasminogen to plasmin, the enzyme that can solubilize the fibrin network in blood clots. streptokinase is currently used in clinical medicine as a thrombolytic agent. it is naturally secreted by β-hemolytic streptococci. methods: to reach an efficient method of purification, an immunoaffinity chromatography method was developed that could puri...

bridged bithiazoles (5,5'-ethylene-4,4'-bithiazoles) are synthesized as a good chelating agent.

background and aims. the aim of this study was to evaluate the antibacterial activity of one-step self-etch adhesives on enterococcus faecalis on days 1, 7 and 14 with the use of modified direct contact test. materials and methods. the modified direct contact test was used to evaluate the antibacterial effect of adper easy one, bond force, clearfil s3 bond, futurabond m, g-bond, ibond and optib...

in a cross section of the patients scheduled for various operations, the plausability of lidocaine as an induction agent is studied and described. the results were dismaying suggesting, henceforth, that as an induction agent, lidocaine altogether fails to accomplish the assignment assigned to this drug.

objective: etching of enamel and dentin is an important step in restoration of teeth with composite resin ensuring the retention of restoration and decreasing microleakage. this in vitro study sought to compare the effects of kimiya and etch-rite acid etchants on the microleakage of composite restorations.   methods: this experimental study was conducted on 30 sound human molar teeth. class v c...

background. hemostatic agents are applied to prepare an isolated bleeding-free condition during dental treatments and can influence adhesive restorations. this study evaluated the effect of a hemostatic agent (viscostat) on microleakage of contaminated dentinal margin of class v composite resin restorations with three adhesives. methods. sixty freshly extracted human molars were selected and cl...

helminths infections are chronic illness in human being and cattle. the use of alternate drugs has been a remedial measure against the resistant strains of helminth parasites, as well as means of reducing the cost of controlling diseases caused by helminthes. pseudocedrelakotschyi is a medicinally valuable plant and possesses various pharmacological properties. p. kotschyi has been traditionall...
