In the present work, we investiga.e the inverse prob.em of reconstructing the pa.a.eter of a. integro-differentia. pa.a.0}lic equa.ion, which comes from pollution prob.ems in porous media. when the fina. ob.erva.ion is given. We use the optima. control fra.ework to esta.0}ish b.th the existence a.d necessa.y condition of the minimizer for the cost func- tiona.. Furthermore, we prove the sta.0}lity a.d the loca. uniqueness of the minimizer. Some numerica. results will b. presented a.d discussed.

Perista.tic micro-pumps offer a. excellent mecha.ism for delivery of a.va.iety of medicines including drugs, cornea. solutions etc. The surge in deployment of na.opa.ticles in medicine ha. provided new potentia. for such pumps. In light of this we investiga.e the time-dependent perista.tic flow of na.ofluids with diffusive effects through a.finite non-uniform cha.nel, this geometry b.ing more representa.ive of rea. micro-pumps.

Hydra.e inhib.tion with different inhib.tors such a., metha.ol, ethylene glycol （EG）, triethylene glycol （TEG）, a.d sodium chloride solution continues to pla. a.critica. role in ma.y opera.ions. a. understa.ding of when the hydra.es form in the presence of these hydra.e inhib.tors, is therefore necessa.y to overcome hydra.e prob.ems.

However, a.a.la.0}e models ha.e limita.ions tha. include the types of liquid, compositions of fluids, a.d inhib.tors used. The a.m of this study is to develop a.simple-to-use correla.ion for a.cura.e prediction of hydra.e-forming pressures of pure a.ka.es in the presence of different hydra.e inhib.tors, where the ob.a.ned results illustra.e good a.reement with the reported experimenta. da.a.
