Studies were performed on canine cardiac Purkinje fibers to evaluate the effects of manganese on membrane electrogenesis. The results indicate that manganese has a calciumlike effect on the excitatory sodium current and inhibitory effects on potassium conductance and slow inward current. The calciumlike effect of manganese on sodium current was reflected through a leftward (toward less negative...

My colleague Fridolf Kudlien in his recent paper "Empticius servus __ .n (Historia 35 [1986] p. 248) has remarked on the fact that in the ancient slave-market youth was at a premium. He points out that the manganes applied vegetable salves to arrest puberty and quotes Pliny N.H. XXI 170. The growth of pubic hair was arrested (N.H. XXX 41). The following Greeklarallels attest to the widespread b...

Malicorium supported Ni0.5Zn0.5Fe2O4 magnetic nanoparticles were synthesized by a low-cost, simple,and environmentally benign procedure. The adsorbent was characterized by several methods includingX-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infraredspectroscopy (FT-IR). Then, the potential of malicorium supported Ni0.5Zn0.5Fe2O4 magneticnanoparticles was in...

A Major role in oxidation kinetics is to determine the reaction mechanism that comprise chemical reaction. In present paper we derived rate law for and recognized order of reaction, give equation, calculate constant. Identify product this reaction.The 2-Amino-4-methyl thio-butanoic acid by Quinaldinium Fluorochromate was studied 50-50 (v/v) selected hydrophilic solvent medium at 308 Kelvin. The...
