Persistent, Depth‐Intensified Mixing During The Western Mediterranean Transition's Initial Stages

Does coarsening begin during the initial stages of spinodal decomposition?

The initial stages of spinodal decomposition were studied by subjecting a critical blend of model polyolefins to a pressure quench and monitoring the evolution by time-resolved small angle neutron scattering. Contrary to the predictions of the widely accepted Cahn-Hilliard-Cook theory, we demonstrate that coarsening of the phase-separated structure begins immediately after the quench and occurs...

Biochemical changes during the initial stages of industrial lead exposure.

Biochemical measurements were carried out on 20 workers entering employment in a lead industry. Blood lead (Pb-B) urinary delta-aminolevulinic acid (ALA), and coproporphyrin (CP) levels were determined before entry and then at approximately weekly intervals for the first 12 weeks of employment. Levels of blood lead began to increase in all men within one week rising from an average pre-employme...

Thermal phase mixing during first-order phase transitions.

The dynamics of first order phase transitions are studied in the context of (3+1)-dimensional scalar field theories. Particular attention is paid to the question of quantifying the strength of the transition, and how ‘weak’ and ‘strong’ transitions have different dynamics. We propose a model with two available low temperature phases separated by an energy barrier so that one of them becomes met...
