Finding Half-life or Doubling Time. Step 1: Identify the given growth or decay rate Step 2: Calculate the Half-life or Doubling Time using the expression. $$t_\frac 12 = \frac{ \ln{2} }{k} $$ $$t_d= \frac{ \ln{2} }{r} $$ Where k is the decay constant and r is...
Question: The half-life of bismuth- 210,{210}Bi, is 5 days.(a) If a sample has a mass of 232mg, find the amount remaining after 15 days.mg(b) Find the amount remaining after t days.y(t)=◻mg(c) ...
for some positive lifespan \(t_0\) . our proof is based on the fokas unified transform method (utm), which is utilized to find a solution formula for the corresponding forced linear problem. then, using this formula we derive linear estimates in bourgain solution spaces which indicate the ...

"Part of the problem for Mike was that we succeeded so much out of the gate with Half-Life," Newell says. "I think he said to himself, 'Do I really want to put my ego and self-worth at risk again?'" Harrington decided the answer was no, in part because he had long planned to...
This is the calculus we have come to, weighing the relative harm of Trump’s stupid-ass statements. But as long as we’re here, let’s keep a little perspective. More people will die from his evisceration of the EPA than will inject Lysol into their blood. ...
That calculus also recognizes that anything you have previously put on the table is not yours anymore. On Hell’s Balls, Mags and Sasha recognize that they put their lives on the table long ago. Just more chips in the pile. In that chapter, I don’t abuse the poker metaphor nearly as...
We then consider a class of sign-changing nonlinearities and prove a monotonicity and a one-dimensional symmetry result, via the same techniques and some general a-priori estimates.doi:10.1007/s00526-011-0405-zAlberto FarinaLuigi MontoroBerardino SciunziCalculus of Variations...
A nonlinear dynamic model for describing shock response of half-sine programmer in shock test is constructed, in which many important factors in half-sine programmer such as size, hard nonlinearity, damping and initial impact velocity are considered, based on the damped Duffing equation, and the ...
First we study the life span of smooth irrotational solutions, i.e., the largest time interval T() of existence of classical solutions, when the initial data are a small perturbation of size from a constant state. Related to this is a decay property for the irrotational part. Then, we ...
