A more accurate analytical approximate expression for the slope at any point of the elastic curve of a slender cantilever column is obtained by using a heuristic but pedagogical derivation. This derivation is based on the linearization of the nonlinear…

Enantiomerically enriched cyanohydrin O-phosphates, prepared
by enantioselective cyanophosphorylation of α,β-unsaturated
aldehydes, react regioselectively at the γ-position
with organocuprates derived from alkyl Grignard reagents
and CuCN to afford chiral γ-alkyl-substituted α,β-unsaturated
nitriles. The configuration of the new C–C double bond
is…

El objetivo de esta investigación ha sido identificar los cambios que se produjeron en la asimilación del esquema corporal, por parte de dos niñas discapacitadas motrices, como consecuencia de la aplicación de un programa de intervención psicopedagógica, en las clases…

The electrochemical homopolymerization of o-aminobenzoic acid has been performed on both gold and graphite surfaces in perchloric acid aqueous medium by cyclic scanning of the potential. Electroactive polymeric materials are formed in all cases but the amount of electropolymerization products…

The mass transport rates to planar electrodes, in a series of electrochemical laboratory filter-press reactors were measured to quantify the effects of the inlet and outlet design manifolds on the fluid flow. In small reactors, entrance/exit effects are especially important…

RÉSUMÉ
Les répercussions du sida sur la communauté intellectuelle préfiguraient un changement certain dans l’esthétique littéraire contemporaine. Le témoignage de l’expérience individuelle de l’écrivain, à cet instant de désarroi collectif et de répression sociale à l’égard de la communauté…
