    Abstract: A simple and highly sensitive method for the determination of Gemifloxacin Mesylate in bulk drug and pharmaceutical formulations. The method is based on the reaction of Gemifloxacin Mesylate with Tb3+ in the presence of hexamine at pH 7.2. The fluorescence was measured at 545 nm after excitation at 271 nm. The calibration graph was linear over the ... Show More

    Abstract: Quality protein maize (QPM) has approximately twice tryptophan (Trp) and lysine (Lys) concentrations in protein compared to normal maize. Because several genetic systems control the protein quality of QPM, it is essential to regularly monitor Trp and/or Lys in QPM breeding programs through laboratory analysis. The objective of the study was to eval... Show More

    Abstract: The experiments were conducted to measure the important parameters in quality of treatment by addition of four different amounts of nano two metal oxides 1, 1.5, 2 and 2.5 gr. The value of zeta potential and oil and grease is investigated. The results show the better performance of nano ferric oxide in coagulation and flocculation by lower amount o... Show More
