ABSTRACT
Ion transport models are compared by simulating the limiting current density of copper deposition from aqueous CuSO(4) solutions on a rotating disk electrode. The first ion transport model is the pseudoideal solution model, on which many commercial electroanalytical simulation tools are built. The second, more rigorous model consists of the linear phenomenological equations for which the activity coefficients and Onsager coefficients are calculated locally with the mean spherical approximation (MSA). The influence of the formal association constant in the pseudoideal solution model is also investigated.
ABSTRACT
Ion transport models are compared by computing the limiting current density of an electrodeposition on a rotating disk electrode for various hypothetical electrolytes. The first ion transport model is the pseudoideal solution model, on which many commercial electroanalytical simulation tools are built. The second, more rigorous model consists of the linear phenomenological equations for which the activity coefficients and Onsager coefficients are calculated locally with the mean spherical approximation (MSA).
ABSTRACT
In this paper, we consider the problem of detecting clustered microcalcification in digitized mammograms using new wavelets with a high Sobolev regularity index. We experimentally assess the superiority of the new wavelets when compared with the classical ones.

We report an adrenal pseudocyst fortuitously discovered in a 30-year-old young woman. Diagnostic of this uncommon pathology is characterized by absence of specific clinical signs and the importance of recent radiologic examinations, echography and NMR. Percutaneous aspiration appears to be warranted prior to or instead of surgery in patients with symptomatic cysts or cystic lesions that do not fulfill the imaging criteria for simple cysts. Treatment is based on adrenal gland resection owing to the seriousness of the potential complications.

Digestion of lactoferrin with pepsin at pH3.0 gave an iron-binding half-molecule that represents the C-terminal part of the native protein. Tryptic or chymotryptic digestion of 30%-iron-saturated lactoferrin yielded the N- and C-terminal half molecules, which could be separated by DEAE-Sephadex chromatography. The N- and C-terminal fragments did not show any immunological cross-reaction. The carbohydrate of lactoferrin was distributed equally between the two fragments.

To constitute a treating team with persons whose roles are not well defined and whose goals are often confuse, and however providing an efficient work ; to have a constant approach despite changing needs and milieu ; to adapt new solutions integrating the social dimension of the child : those are the three tasks which US child psychiatry teams are apparently working on.
