Review ArticleOpen accessIn the keywordsAbout Homeopathy or ≪Similia Similibus Curentur≫Raffaella Aversa, Relly Victoria V. Petrescu, Antonio Apicella, Florian Ion T. PetrescuHomeopathy or homoeopathy (from the Greek όμοιος/homoios, "similar" and πάθος/pathos, "suffering" or "disease") is a science created by Samuel Hahnemann in 1796. The homeopathic practice rests on three principles: The similarity, the individualization of cases and the infinitesimal. The use of the infinitesimal was proposed by Hahnemann in the early nineteenth century with the publication of "Organon der Heilkunst" (Organon … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 16 Dec 2016 · 11,553 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCOLORIMETRIC DETERMINATION OF CEFQUINOME SULPHATE IN BULK AND DOSAGE FORM USING AMMONIUM MOLYBDATEShaza Wageialla Shantier, Elrasheed Ahmed GadkariemThis study was designed to develop two colorimetric methods for the determination of Cefquinome Sulphate (CS) in bulk and dosage forms using two different concentrations of molybdenum solution. The developed methods were based on the oxidation of CS with 2% ammonium molybdate, in the presence of sulphuric acid, producing a green colored product with λmax at 409 nm (Method I) … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 20 Dec 2013 · 7,051 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDetermination 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 · 8,199 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDetermination 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 · 8,025 accessesView PDF Cite
