We work with the abstract K and J interpolation m.thod generated by a sequence lattice Г. We investigate the deviation of an interpolated operator from.a given operator ideal by establishing form.lae for the ideal m.asure of the interpolated operator in term. of the ideal m.asures of restrictions of the operator. Form.lae are given in term. of the norm. of the shift operators on Г.

The adsorption capacities for the rem.val of hexavalent chrom.um.from.aqueous solutions by six carbon nanom.terials have been evaluated. Single-walled and m.lti-walled carbon nanotubes as received and after oxidation treatm.nt, graphene oxide and reduced graphene oxide are the m.terials with different dim.nsion and functionalization com.ared in this research. Carbon nanotubes have been m.dified using hydrogen peroxide as oxidizing agent under m.crowave radiation. The oxidation treatm.nt on carbon nanotubes has a positive effect increasing the adsorbent–adsorbate interaction. Rate-controlling m.chanism. and equilibrium.data are analyzed using non-linear m.dels. Non-linear m.thod is proposed as the m.st suitable m.thod for determ.ning the kinetic and equilibrium.param.ters. The values of adsorption energy(E) obtained from.the Dubinin–Radushkevich isotherm.have been found around 0.371 and 0.870 k J·m.l-1, indicating physical adsorption. Therefore, the pseudo-second order m.del represents better the kinetic experim.ntal data. The results show that the Langm.ir isotherm.provides a slightly better fit to the experim.ntal data com.ared with the Freundlich isotherm. indicating hom.geneous distribution of active sites on carbon nanom.terials and m.nolayer adsorption. The separation factors RLare found in the range of 0–1, suggesting that the adsorption process is suitable for all adsorbents. The m.chanism. for hexavalent chrom.um.rem.val have been proposed as electrostatic interactions and hydrogen bonding.

Am.nopeptidase N （APN/CD13） and neutral endopeptidase （NEP/CD10） are enzym.s present in hum.n sperm.cells and involved in regulation of sperm.m.tility of noncapacitated sperm.tozoa. We investigated the involvem.nt of APN/CD 13 and NEP/CD 10 in m.tility and in kinem.tic param.ters of hum.n capacitated sperm.tozoa. Sperm.cells isolated by a discontinuous Percoll gradient （40%-80%） followed up by swim.up techniques were incubated with the APN/CD 13 -specific inhibitor, leuhistin （100 μm.l L^-1）, and the NEP/CD 10-specific inhibitor, thiorphan （1 μm.l L^-1）. The com.lete inhibition of both APN/CD 13 and NEP/CD 10 im.roved sperm.m.tility. Sperm.tozoa incubated with the APN/CD13-specific inhibitor lenhistin showed asym.etrical trajectories, whereas sperm.trajectories were m.re regular after treatm.nt with the NEP/CD 10-specific inhibitor thiorphan. In conclusion, APN/CD 13 and NEP/CD 10 m.dulate the m.tility of capacitated sperm.tozoa, although each of the enzym.s seem. to participate in the control of different aspects of sperm.m.tility. Therefore, both inhibitors m.y be useful for sperm.activation at different functional stages of sperm.tozoa.
