In this situation it is generally uncommon to talk about half-life in the first place, but sometimes people will describe the decay in terms of its "first half-life", "second half-life", etc., where the first half-life is defined as the time required for decay from the initial value to 50%, the second half-life is from 50% to 25%, and so on.
Absorption half-life 1 h, elimination half-life 12 h. Biological half-life (elimination half-life, pharmacological half-life) is the time taken for concentration of a biological substance (such as a medication) to decrease from its maximum concentration (C max) to half of C max in the blood plasma.
For any integer n, n ≡ 1 (mod 2) if and only if 3n + 1 / 2 ≡ 2 (mod 3). Equivalently, 2n − 1 / 3 ≡ 1 (mod 2) if and only if n ≡ 2 (mod 3). Conjecturally, this inverse relation forms a tree except for a 1–2 loop (the inverse of the 1–2 loop of the function f(n) revised as indicated above).
2.6 × 10 11 Qs (8.2 × 10 33 years): The smallest possible value for proton half-life consistent with experiment [19] 10 23 Qs ( 3.2 × 10 45 years ): The largest possible value for the proton half-life , assuming that the Big Bang was inflationary and that the same process that made baryons predominate over antibaryons in the early Universe ...
Currently, the most precise results come from the Super-Kamiokande water Cherenkov radiation detector in Japan: [13] a lower bound on the proton's half-life of 2.4 × 10 34 years via positron decay, and similarly, 1.6 × 10 34 years via antimuon decay, close to a supersymmetry (SUSY) prediction of 10 34 –10 36 years.
