In this work, the results concerning to the mean activity coefficient measurements for NaCl in the (glycerol + water) system using the potentiometric method are reported. The potentiometric measurements were performed on the galvanic cells without liquid junction of the type: Ag|AgCl|NaCl (m), glycerol (wt%), H2O (1 - wt)%|Na-ISE, in various mixed solvent systems containing 0, 5, 10,...

The redox behavior for bulk and nano silver nitrate (NSN) were studied by cyclic voltammetry technique in absence and presence of cefdinir antibiotic (CFD) using glassy carbon electrode (GCE) in 0.1 M KNO3 as supporting electrolyte at two different temperatures. Scan rates were studied for the redox reactions of bulk and nano silver nitrate (NSN) in absence and presence of cefdinir antibiotic (...

in this research we work with the effective hamiltonian and the quark model. we investigate the decay rates of matter-antimatter of quark. we describe the effective hamiltonian theory and apply this theory to the calculation of current-current ( ), qcd penguin ( ), magnetic dipole ( ) and electroweak penguin ( ) decay rates. the gluonic penguin structure of hadronic decays is studied through th...

Three commonly used systems of vectorcardiography are compared on an absolute and direct quantitative basis in terms of equations, geometric interpretations, scalar leads and vectorcardio-grams, using experimental results obtained on an accurate, three-dimensional homogeneous torso model of the human subject with a dipole fixed in position in the center of the heart. It is concluded that the ac...

This article is a report on a novel and high-stability biosensor with minor interference effects of surface modification of working electrode with β-Ga2O3 nanowires (NWs) on choline oxidase biosensor were investigated in an electrochemical detection system. β-Ga2O3 NWs were materialized on the silicon substrate in a catalyst-free growth mechanism. The β-Ga2O<sub...
