In the latter process, temperature inside the engine

Later on, in 1958, BELOUSOV |59-1| discovered, also by chance, a new periodic chemical reaction as he was studying, in an acidic homogeneous medium, the citric acid oxidation by potass

https://doi.org/10.1007/978-3-658-34601-0ity are helpful for systematic investigations of these remarkable phenomena. An almost ideal system of this sort are the polarized nuclear spins of a solid in a magnetic field and embedded in a resonant structure. There, nuclear magnetic resonance (NMR) becomes feasible for which sophisticated exper
