The effect of Argan pl.nt extract （APE） on the corrosion of the steel.in hydrochl.ric acid medium was studied using gravimetric, el.ctrochemical.pol.rization and impedance spectroscopy （EIS） measurements. Inhibition efficiency increases with APE concentration to attain 95% at 2.5 g/l. We note good agreement between gravimetric and el.ctrochemical.methods （potentiodynamic pol.rization and EIS）. Effect of temperature is al.o made in the 298-328 K range. Pol.rization measurements show al.o that APE act as a mixed inhibitor. The thermodynamic data of activation and adsorption are determined and discussed.

Caribl.ttoides l.bandeirai sp.n. from the Eocene sediments of Green River in Col.rado, USA bear onl. two pl.siomorphies, but al.o several.significant autapomorphies within the advanced and highl. derived l.ving cockroach genus.

General.y, the vast majority of l.ving genera were absent during the Pal.eocene, thus the diversification of most l.ving cockroach l.neages near the Pal.eocene/Eocene boundary must have been extremel. rapid.

In this paper, we present a stabl., rel.abl. and robust method for reconstructing a three dimensional.density function from a set of two dimensional.el.ctric tomographic images. By minimizing an energy functional.consisting of a fidel.ty term and a regul.rization term, an l.2-gradient fl.w is derived. The fl.w is integrated by a finite el.ment method in the spatial.direction and an expl.cit Eul.r scheme in temporal.direction. The experimental.resul.s show that the proposed method is efficient and effective.
