Compensation effect and volcano curve in toluene hydrogenation catalyzed by transition metal sulfides.

Within the framework of volcano curves, a kinetic study of toluene hydrogenation catalyzed by transition metal sulfides highlights the variation of the apparent kinetic parameters as a function of the ab initio sulfur-metal bond energy descriptor and sulfo-reductive reaction conditions.

[A serological survey of rubella among pregnant women in Abidjan (author's transl)]. / Pévalence sérologique de la rubéole chez la femme enceinte à Abidjan.

A serological survey about the prevalence of the rubella hemagglutination inhibiting antibodies among the pregnant women in Abidjan during the year 1975 has shown an average rate of seroconversion of 84 p. 100. This rate depends on age and increases from 70 to 80 p. 100 between 15 and 35 years old. A regression line is fitted, and the goodness of fit is tested. These rates are in accordance with what is presently observed in America, in Europe and in Australia.

[Study on correlations between certain biological parameters and the Achillean reflexogram in a homogeneous African population (author's transl)]. / Recherche de corrélations entre quelques paramétres biologiques et le réflexogramme Achilléen d'une population Africaine homogéne

Study of a homogenous population comprising 25 male Africans. The following parameters have been measured: proteinemia, hematocrit, natremia, calcemia, globular and plasmatic magnesemia, duration of the achillean reflexogram. Hyperproteidemia and hypomagnesemia, which are usually observed in African people, were found. A negative linear relationship significant at the 10 0/0 threshhold has been demonstrated between the reflexogram and the P.B.I. value.
