Traveling-stripe forcing generates hexagonal patterns.

We study the response of Turing stripe patterns to a simple spatiotemporal forcing. This forcing has the form of a traveling wave and is spatially resonant with the characteristic Turing wavelength. Experiments conducted with the photosensitive chlorine dioxide-iodine-malonic acid reaction reveal a striking symmetry-breaking phenomenon of the intrinsic striped patterns giving rise to hexagonal lattices for intermediate values of the forcing velocity. The phenomenon is understood in the framework of the corresponding amplitude equations, which unveils a complex scenario of dynamical behaviors.

Vectorelectronystagmography. A new analysis technique.

We propose herein a new system of derivation for vectorelectronystagmography that minimizes the errors in interpretation of eye movement from the experimental data. The conventional three-point analysis may result in errors as large as 35% in comparison with the proposed technique.

[A psychosomatic approach to perennial allergic rhinitis].

The objective of this investigation is to study the involvement of the psychological process in the etiology of perennial allergic rhinitis. Thirty patients with perennial allergic rhinitis, submitted to a Program of Hyposensibilization to Home Dust at the ENT Department, were selected. All patients were studied through psychological interviews and Pfister Colored Pyramid Test. Our results were compared to those obtained by Robert Heiss in his studies of standardization parameters (non rhinitic sample). The study revealed that our patients present intrinsic psychological difficulties characteristic of failures in the affective--emotional development and points out to a neurotic line of personality structuration.
