Tailoringmembrane nanostructure and charge densityfor high electrokinetic energy conversion efficiencyTheelectrokinetic energy conversion (EKEC) of hydraulic work directlyinto electrical energy has been investigated in charged polymericmembranes with different pore charge densities and characteristicdiameters of the nanoporous...
Original article arterial reservoir-excess pressure and ventricular work... Using cal-culus of variations and mass conservation, which relates the flow and rates of change of pressure in the vessels, we show that the reservoir pressure waveform minimises the ventricular hydraulic work for any physiologically or clinically reasonable ejection waveform and arterial properties, i.e....
Irrigation communities in the roman world through epigraphic sources and justinian’s digest... These ‘associations’ dealt with different matters such as: a) the distribution of water; b) the regulation of the hydraulic work, such as digging and maintenance;and c) the arbitration of possible disputes between users....
