A densimeter technique was used to make a kinetic analysis of the rate of swelling of human erythrocytes suspended in 1% NaCl following successive additions of NH(4)Cl. Two series of experiments were performed, one in the absence of and the other in the presence of 6 x 10(-4)M NaHCO(3). An analysis of the data using Widdas's equations gave a family of curves in each instance. When LeFevre's equ...

Chloride ingress is strongly associated with the properties of pores in recycled concrete. To unlock its role chloride permeability, pore structures concrete containing various quantities coarse (fine) aggregates were analyzed from multi-scales, and outcomes further verified by statistical investigation. The results show that different roles played terms concrete, as reflected their volume diam...

Unidirectional chloride effluxes from small bundles of muscle fibers were measured under equilibrium conditions. It was found that chloride effluxes are described by the constant field theory with a chloride permeability constant, P(cl), which is independent of the chloride concentration and the membrane potential. The value of P(cl) at neutral pH was found to be 5 x 10(-6) cm/sec. Chloride mov...
