We present the RUPTURA code (https://github.com/iraspa/ruptura) as a free and open-source software package (MIT license) for (1) simulation of gas adsorption breakthrough curves, (2) mixture prediction using methods like Ideal Adsorption Solution Theory (IAST), segregated-IAST explicit isotherm models, (3) fitting models on computed or measured data. The combination with RASPA enables computati...

rankE(Q) ? = ords=1 L(E/Q, s). This rank conjecture is known when ords=1 L(E/Q, s) ≤ 1 (Gross-Zagier, Kolyvagin, ...). The recent breakthrough of Bhargava-Skinner-W. Zhang shows that the rank conjecture holds for at least 66% of all elliptic curves over Q. Even more interestingly, BSD further predicts a refined BSD formula for the leading term of L(E/Q, s) at s = 1 in terms of various important...

In this study, the Bohart and Adams’ model taking into account bed depth, and influent dye concentration was studied to exhibit adsorption process of textile dyes (Basic Blue 41 – BB41 and Reactive Black 5 – RB5) in glass columns using tree barks (Eucalyptus camaldulensis). Adsorption capacity coefficient values are determined using the Bohart and Adams’ bed depth service model. The model indic...

The dynamic adsorption of Pb(II) ions from aqueous solutions using a granulated activated carbon and an activated carbon cloth has been studied using fixed bed adsorption column. The breakthrough curves at different hydraulic loading rates (HLR), bed depth and feed concentration (Co) have been examined. The breakthrough time at any given concentration of the effluent decreases with increasing h...
