in this work g'/g-expansion method has been employed to solve (2+1)-dimensional dispersive long wave equation. it is shown that g'/g-expansion method, with the help of symbolic computation, provides a very effective and powerful mathematical tool, for solving this equation.
in this paper, based on sinh-cosh method and sinh-gordon expansion method,families of solutions of (2+1)-dimensional breaking soliton equation are obtained.these solutions include jacobi elliptic function solution, soliton solution,trigonometric function solution.
Neither the seroprevalence of HIV-2 nor the sensitivity of enzyme immunoassays for the detection of antibodies to this retrovirus have been defined in Thailand. We, therefore, Investigated these enigmas using banked sera previously screened for HIV-1 by a test that did not distinguish between HIV-1 and HIV-2. All 1,013 HIV-seroreactive specimens were positive to HIV-1 on retesting, and 740 (73%...
A novel luminescent biscyclometalated iridium(III) complex [Ir(C^N)2bpy]PF6 (Ir-S, bpy = 2,2'-bipyridine) containing two 2-phenylpyridine (ppy) cyclometalating ligands (C^N) functionalized with 1,3-dithiane for the detection of Hg(2+) ions has been synthesized and characterized by spectroscopic and photophysical measurements. The luminescence of Ir-S exhibits a ratiometric response upon the add...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
A Derivatives of 2-thiouracil are characterized by wide spectrum biological activity, which is characteristic most representatives this heterocycles class. In particular, 2-(2-oxo-2-phenylethylthio)-pyrimidin-4(3H)-ones belong to the group non-nucleoside inhibitors HIV-1 reverse transcriptase. The antimalarial properties 2-(2-oxo-2-phenylethylthio)-4-R-pyrimidine derivatives, proved be effec...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
