Experimental study and simulation of Zn production via proton induce reaction.

The Zn was produced by16.8 MeV proton irradiation of natural copper. Thick target yield for Zn in the energy range of 16.

Spectrofluorimetric determination of cefixime using terbium-danofloxacin probe.

Objectives: Cefixime (Cfx), is a semi-synthetic third-generation oral cephalosporin antibiotic that is prescribed for the treatment of susceptible infections. There are some procedures for the determination of Cfx in pharmaceutical formulations and biological samples. Herein a spectrofluorimetric method was proposed for Cfx determination based on the fluorescence quenching of terbium-danofloxacin (Tb(3+)-Dano) in the presence of Cfx.

Analysis of losartan and carvedilol in urine and plasma samples using a dispersive liquid-liquid microextraction isocratic HPLC-UV method.

Background: A simple, precise and sensitive HPLC method has been developed for simultaneous determination of carvedilol and losartan in human plasma and urine samples. The analytes were extracted by a dispersive liquid-liquid microextraction method. A mobile phase of 15 mM sodium dihydrogen phosphate buffer (pH 4.

Comparison of stresses induced by fiber post, parapost and casting post in root canals by photoelasticity method.

Introduction: Many studies have been performed to evaluate the stress distribution around endodontic posts; those which compared posts composed of different materials are rare. The aim of this study was to compare stresses induced in dentin by three structurally different posts using photoelasticity method.

Materials And Methods: Nine blocks of PSM-5 Photoelastic material with 45×45×10 mm dimension were prepared.
