4/3/2010· On heat-transfer surfaces, calcium carbonate scale formation is believed to be initiated at three phases: CO2 gas, metal surface, and water boundary [13,14]. At lower temperatures (below 30°C), in the absence of gas bubbles, it was suggested that the calcite crystallites formed adhere onto the substrate where they subsequently outgrow, forming compact layers which have a dramatic effect on

Calcium Binding - an overview | ScienceDirect Topics

Calcium binding causes an opening of the N-terminal domain of TnC which exposes the TnI binding site, allowing TnI to bind. The binding of the switch peptide to this TnC site requires the dissociation of the inhibitory peptide of TnI from actin. Thus the system is a set of poised equilibria.
