WebMar 23, 2024 · Chronic exposure of the kidney to the downstream effects of hypokalemia can ultimately result in tubulointerstitial injury and fibrosis—the essence of hypokalemic nephropathy. In the proximal tubule, hypokalemia increases the production of ammonia (NH 3 ) from the cellular metabolism of glutamine.WebNov 17, 2024 · Heaviside Function. The Heaviside or unit step function (see Fig. 5.3.1) , denoted here by uc(t), is zero for t < c and is one for t ≥ c; that is, uc(t) = {0, t < c; 1, t ≥ c. The precise value of uc(t) at the single point t = c shouldn’t matter. The Heaviside function can be viewed as the step-up function.
