Research ArticleOpen accessPhrase in the titleDetermination of Ibuprofen and Paracetamol in Binary Mixture Using Chemometric-Assisted Spectrophotometric MethodsWafaa S. HassanThree methods are presented for simultaneous determination of ibuprofen and paracetamol without previous separation. The first method depends on first derivative UV spectrophotometry, with zero-crossing measurement. The first derivative amplitudes at 230 and 290 nm were selected for the assay of ibuprofen and paracetamol, respectively. The second method depends on first derivative of the ratio-spectra by measurements of the amplitudes … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 8,205 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleDetermination of Metoprolol and Felodipine in Binary Mixture Using Chemometric-Assisted Spectrophotometric and High-Performance Liquid Chromatographic-UV MethodsHesham Salem, Ola M. AbdallahFour methods were developed for simultaneous determination of metoprolol and felodipine without previous separation. In the first method both drugs were determined using first derivative UV spectrophotometry, with zero crossing measurement at 222 and 235 nm for metoprolol and felodipine, respectively. The second method depends on first derivative of the ratios spectra by measurements of the amplitudes at 250.1 nm … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 8,028 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleCorrosion of Copper Metal in Presence of Binary MixturesMedhat A. Shaker, Hanaa H. Abdel-RahmanThe rates of copper corrosion were determined in presence and in absence of different compositions of water-ethanol, -ethylene glycol, -glycerol, -dimethyl sulfoxide (DMSO) and -dioxane binary mixtures. The rates of corrosion were found to decrease by increasing the concentration of solvents. The percent inhibition range from 10.9 to 78.2% depends on the nature of solvent and its concentration. The calculated … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 8,234 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleDetermination of Diloxanide Furoate and Metronidazole in Binary Mixture Using First Derivative of the Ratio-Spectra and High-Performance Liquid Chromatography-UV MethodsNora H. Al-ShaalanTwo methods are presented for simultaneous determination of diloxanide furoate and metronidazole. The first method depends on first derivative of the ratio-spectra by measurements of the amplitudes at 242.5 and 285.5 nm for diloxanide furoate and 225.5 and 300 nm for metrinidazole. Calibration graphs were established for 2-100 μg mL-1 for diloxanide furoate and 1-50 μg mL-1 for metronidazole. In … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,719 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudy of the Thermodynamic Equilibrium of Fragrance Mixtures, Limonene, Linalool and Geraniol, using the Unifac and Cosmo-Sac Models and the Estimation of their Combined Properties in Binary, Ternary and Quaternary MixturesLavínia Mota Cristianismo Silva, José Izaquiel Santos da Silva, Rogério Alexandre Alves de Melo, Edilailsa Januário de MeloPerfume is a non-ideal complex mixture of chemicals originating from the extraction of essential oils and these oils are volatile components extracted from plants, some animals, or even synthesized. For this reason, to compose a fragrance, there are countless possibilities to combine one element and another, which makes the process slow and expensive. Therefore, in this study, we will combine … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 2 · 14 Jun 2022 · 7,462 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMinimum and Complete Fluidization Velocity for Sand-Palm Shell Mixtures, Part II: Characteristic Velocity Profiles, Critical Loading and Binary CorrelationsV. S. Chok, A. Gorin, H. B. ChuaProblem statement: In Part I of this research, the main features of the fluidization behavior and characteristic velocities had been reported. Approach: In the present research, the mixtures characteristic velocity profiles for various sand sizes, palm shell sizes and weight percents were presented. It was recognized that there are instances where the characteristic values remain nearly unchanged from its pure … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,428 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Binary and Ternary Models in Powder Packing Density for Additive Manufacturing ApplicationsTaher M. Abu-Lebdeh, Oluwatobiloba Adetokunbo KalejaiyePowder packing is a very important aspect of additive manufacturing (3-D printing), as it directly impacts the final physical and mechanical properties of the printed objects. Improving the packing density of powder directly impacts the microstructure of the finished 3D-printed product, which also contributes to the surface finish. In order to achieve the densest packing for a powder, different sizes … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 15 Jun 2021 · 7,284 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMinimum and Complete Fluidization Velocity for Sand-Palm Shell Mixtures, Part I: Fluidization Behavior and Characteristic VelocitiesV. S. Chok, A. Gorin, H. B. ChuaProblem statement: Palm shell on its original state cannot be fluidized solely. However, mixing palm shell with a second fluidizable material can facilitate proper fluidization. Approach: The minimum and complete fluidization velocity (Umf and Ucf) for sand/palm shell binary mixtures had been studied in a partitioned reactor known as Compartmented Fluidized Bed Gasifier (CFBG). The pilot scale reactor ID is … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,221 accessesView PDFCite
Research ArticleOpen accessIn the keywordsChelation Study of Captopril with Cd2+ and Pb2+ IonsMohammad Joshaghani, M.B. Gholivand, A.R. MosavatThe protonation constants of Captopril, (1-(3-mercapto-2-(S)-methyl-1-oxopropyl)-S(L) proline, (CPL) and stabilities of its two divalent metal ions Cd(II) and Pb(II) were determined potentiometrically in two different metal to ligand ratio 1:1 and 1:2 systems and in water and methanol-water binary mixtures using the computer Best program. Two protonation constants were obtained which were assigned to the carboxylic and thiol groups.

Research ArticleOpen accessIn the abstractThe Bidispersed Model System and Binary System for FerrofluidsJian Li, Decai LiFerrofluids, dispersions of magnetic nanoparticles, are typical dipolar fluids whose behaviors can be modified using an external magnetic field. Such magnetically controlled effects result from interactions between the magnetic particles, which are enhanced by an applied magnetic field. Since the system of particles always possesses a size distribution, real ferrofluids represent a polydispersed system. A theoretical model of a bidispersed … …Physics International, Vol. 3, Issue 1 · 28 Jan 2013 · 7,003 accessesView PDFCite
