Research ArticleOpen accessEvery word in the titleA New Spectrophotometric Method for Determination of Iron in Herbs, Spices and Beans with 2,6-Diacetylprydine Dioxime and 2-Acetylpyridine MonoximeZ. R. Komy, E. A. Abu-Gharib, A. DesokyThe reaction of iron (II) with 2, 6-diacetylprydine dioxime (H2dapd) and 2-acetylprydine monoxime (Hapm) in 10% and 60% v/v ethanol-water solution at pH 2.5 and 7.5, respectively, were studied using direct and first derivative spectrophotometry. Fe (III) is reduced by H2dapd and gives iron (II) complex. A simple, rapid, selective and sensitive method for the determination of Fe (II), Fe … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,960 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCharacterization of Reconstructed Basins Using Pattern Spectrum ProcedureP. RadhakrishnanSeveral classical and Fractal binary shapes, which are akin to geophysical shapes such as basins, lakes, and pore-grain spruce, are analyzed and characterized by employing various mathematical morphological transformations, and methods. By employing rhombus, square and octagon structuring elements, these shapes are decomposed into their skeletal networks and their corresponding skeletal network subsets are dilated to the respective degree by … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,932 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBinding of the scutellarin to albumin using tryptophan fluorescence quenching, CD and FT-IR spectraJianniao Tian, Jiaqin Liu, Zhide Hu, Xingguo ChenThe binding of scutellarin with bovine serum albumin (BSA) was investigated at three temperatures, 296k, 310K, and 318K, by the fluorescence, circular dichroism (CD) and fourier transform infrared spectroscopy (FT-IR) at pH 7.40. The binding parameters were determined by Stern-Volmer equation. The thermodynamic parameters were calculated according to the dependence of enthalpy change on the temperature as follows:ΔH0 and ΔS0 … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 13,643 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpectrofluorimetric, Atomic Absorption Spectrometric and Spectrophotometric Determination of Some FluoroquinolonesHesham SalemSimple, accurate, sensitive and selective spectrofluorimetric, atomic absorption spectrometric and spectrophotometric methods are described for the quantitative determination of ten fluoroquinolones (amifloxacin, ciprofloxacin hydrochloride, difloxacin hydrochloride, enoxacin, enrofloxacin, lomefloxacin hydrochloride, levofloxacin, norfloxacin, ofloxacin and pefloxacin mesylate). The first method was a spectrofluorimetric method in which samples of the studied drugs in 0.1 N H2SO4 showed native fluorescence at 450 nm … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,317 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePower Analysis on Same Filter Different Sources for Selection of Spectral Filters in Optical DemultiplexerMohammad Syuhaimi Ab-Rahman, Hadiguna, Latifah Sarah SupianThe cost effective demultiplexer based on POF is reported in this study. The demultiplexer is fabricated by combining optical splitter with the suitable filter for wavelength selection. Therefore this study we aims to evaluate the effectiveness of selected color filter film for demultiplexer construction where only signals with certain wavelengths are allowed to pass through the demultiplexer while the other … …Journal of Computer Science, Vol. 9, Issue 7 · 18 Jun 2013 · 6,548 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSelection of Spectral Filters for Optical Demultiplexer Via Same Source Different Filters Testing TechniqueMohammad Syuhaimi Ab-Rahman, Hadiguna, Latifah Sarah Supian, Malik SulaimanThis study aims to evaluate the effectiveness of selected color filter film for demultiplexer construction where only signals with certain wavelengths are allowed to pass through the demultiplexer while the other signal that carrying different wavelengths are absorbed. Characterization testing and analysis is done based on recorded data. Demultiplexer components are characterized by the Same Source at Different Filters (SSDF) … …Journal of Computer Science, Vol. 9, Issue 4 · 9 May 2013 · 6,247 accessesView PDFCite
