What is the difference between mathematical R^4 space and physical 4D unit space?

We assume that the difference is huge and that it is not possible to compare the two spaces. The R^4 mathematical space considers time as an external controller and the space itself is immobile in...

In the presence of VERY high concentration (1000 ppm) of silicon, the adsorption isotherms of arsenic are showing anomalous trends, why so?

I conducted an adsorption experiment of arsenic on soil in the presence of different doses of silicon as competing ions to see the effect of silicon on arsenic adsorption and desorption. I took 5...

Why most of the research paper give pseudo first order and pseudo 2nd order kinetics and then isotherm of Langmuir, Freundlich?

The isotherms needs qe from different ce, in that case for both pseudo 1st and pseudo 2nd order there should be separate Langmuir and Freundlich isotherms. If in case of isotherm the research...
