[Recurrent organic abdominal pain. Psychosocial investigation].

This study has produced the following results. All the children with RAP show an excessive excitability and timidness, a strong insecurity and apprehension towards the society. The majority of the children show a strong dependence upon their relatives, they are not able to place themselves, as active subjects, in the present trality and to make plans for their future life (absence of interests and/or programmes about their autorealization). These children have a psychological maturity not corresponding to the physical one, even if there is no real strongly marked mental insufficiency. About 50% of the subjects have difficult relations with their siblings, friends and teachers, unlike the group examined (infact these difficulties are not seen).

[The role of the blood viscosity and hematocrit value in acute stroke. Experimental considerations].

The link between blood viscosity, Ht and the onset of stroke is highlighted and reports in the literature are examined. On this basic, the paper proposes an experimental model of cerebral ischaemia in the rabbit as providing a better insight into this aspect which may be highly significant, particularly in the prevention of strokes.

Raman characterization of single-walled nanotubes of various diameters obtained by catalytic disproportionation of CO.

Single-walled carbon nanotubes prepared by disproportionation of CO over Co-Mo/SiO2 catalysts have been characterized by Raman spectroscopy, using several excitation energies. By varying the reaction temperature, different ranges of nanotube diameter were obtained. The average diameter of a single-walled nanotube produced at 750 degrees C was 0.9 nm, while it increased up to about 1.5 nm when the synthesis was conducted at 950 degrees C. The analysis of the Raman spectra obtained with a range of laser excitation energies not only gives a definite description of the single-walled nanotubes diameters but also helps differentiate the metallic or semiconducting character of the samples. This analysis can be done by comparing the experimental data with calculated gap energies as a function of nanotube diameter as well as comparing the relative intensity of bands centered at 50-60 cm-1 lower than the tangential G mode. The analysis of this feature, which can be fitted with a Breit-Wigner-Fano line, offers a method for distinguishing between metallic and semiconducting single-walled carbon nanotubes.
