Abstract Experiments investigating particles floating on a randomly stirred fluid show regions of very low density, which are not well understood. We introduce simplified model for understanding sparsely occupied the phase space non-autonomous, chaotic dynamical systems, based upon an extension skinny bakers’ map. how distribution sizes voids in can be mapped to statistics running maximum Wiene...

15N NMR spectra were taken of 15N-enriched tRNA extracted from bakers yeast; ammonium sulfate was used as a nitrogen source. The increase in the degree of denaturation of tRNA, which occurs with increase in temperature from 30 degrees C to 70 degrees C, resulted in no large changes in 15N chemical shifts at acidic and neutral pH but quite pronounced changes in proton-15N nuclear Overhauser effe...

The complete amino acid sequence of chicken heart cytochrome c has been established. This primary structure is typically that of a “mammalian-type” cytochrome c showing the characteristic groupings of hydrophobic and basic residues, and, like the other cytochromes c from vertebrate species, has an acetylated amino-terminal residue. Chicken heart cytochrome c differs from the horse, beef, human,...
