The literature on exfoliative dermatitis of the newborn, first described by Ritter von Rittershain in i878, is meagre and almost all of the papers have been reports of sporadic cases which suggested a cause or were remarkable for recovery after some one or other method of treatment. What appears to be the extremely uncommon occurrence of the malady in Britain is supported by the fact that Halle...

Diffusional resistance in the porous particle is important in adsorption and reaction engineering. For a porous adsorbent particle subjected to an arbitrary change in the surrounding Ž . fluid-phase concentration, Glueckauf 1955 derived the linŽ . ear driving force LDF approximation that relates the average adsorbate concentration inside the particle directly with the concentration in the fluid...

The direct three component modified Mannich reaction via condensation of aldehydes, 2-naphthol or 2,7-naphthalendiol and piperidine to generate Betti bases has been carried out over L-proline (20 mol%) with high efficiency under solvent free conditions at 70 OC. Also, the reaction of aromatic aldehyde and 4-hydroxycoumarin in the presence of L-proline (20 mol%) in the ethanol under reflux condi...
