13C Nuclear Magnetic Relaxation of Poly(D-glutamic acid) in Aqueous Solution

Combined action of static and alternating magnetic fields on ionic current in aqueous glutamic acid solution.

Combined parallel static and alternating magnetic fields cause a rapid change in the ionic current flowing through an aqueous glutamic acid solution when the alternating field frequency is equal to the cyclotron frequency. The current peak is 20-30% of the background direct current. The peak is observed with slow sweep in the alternating magnetic field frequency from 1 Hz-10 Hz. Only one resona...

Action of combined magnetic fields on aqueous solution of glutamic acid: the further development of investigations

In the present work the results of the known investigation of the influence of combined static (40 microT) and alternating (amplitude of 40 nT) parallel magnetic fields on the current through the aqueous solution of glutamic acid, were successfully replicated. Fourteen experiments were carried out by the application of the combined magnetic fields to the solution placed into a Plexiglas reactio...

Molecular Mobility of Sucrose in Aqueous Solution Studied by 13C NMR Relaxation

From the tem perature and concentration dependence o f the 13C spin lattice relaxation times o f the 12 carbon atom s o f the sucrose molecule the ro ta tional dynam ics o f the sugar molecules are determ ined. N o indication for conform ational m obility o f the rings is found. The exocyclic hydroxym ethyl groups possess extra m obility. The m odels used for the description are critical­ ly di...

Characterisation of weak magnetic field effects in an aqueous glutamic acid solution by nonlinear dielectric spectroscopy and voltammetry

BACKGROUND: Previous reports indicate altered metabolism and enzyme kinetics for various organisms, as well as changes of neuronal functions and behaviour of higher animals, when they were exposed to specific combinations of weak static and alternating low frequency electromagnetic fields. Field strengths and frequencies, as well as properties of involved ions were related by a linear equation,...
