You also need to reply-all so the mailing list stays in the loop. -- Sent from my phone. Please excuse my brevity.

Should I repost the question with reply-all?

Hello, I am working on a small data set and trying to find values of Qmax and Kl for the equation qe = (Qmax * Kl * ce) / (1 + ?l* ce) I found my Qmax and Kl through the linear model butam now trying to find them through the "nls" function however an error comes up that I am unfamiliar with. I have the file loaded for reference. Any help is appreciated. Thank you. -Timothy

Hello, I am having troubles with heat conduction problem. Below is the given information. Should I move forward with this problem like any other 1-D PDE? ?T/?t = a* (?^2T/?x^2) I.C. For t = 0 and 0 ? x ? 10, T = 0 ?C B.C. For x = 0 cm and all t , T = 100?C For x = 10 cm and all t , T = 0 ?C The thermal diffusivity is a = 2.0 cm^2 /s. I also added what I have for code in R. Any help will
