An electrogenic proton-translocating ATPase (H+-ATPase) has been described in turtle urinary bladder and bovine and rat renal medulla. In the present study, a membrane fraction with ATP-dependent H+ transport activity was isolated from human renal medulla. Intravesicular acidification was assessed by acridine orange absorbance changes. Proton transport was(More)
In cement-based materials porosity plays an important role in determining their mechanical and transport properties. This paper describes an improved low–cost embeddable miniature NMR sensor capable of non-destructively measuring evaporable water loss and porosity refinement in low and high water-to-cement ratio cement-based materials. The sensor consists(More)
