The Relationship of Prenatal Hemoglobin to the Hemoglobin of the Newborn Infant**Presented at the Sixteenth Annual Meeting of the South Atlantic Association of Obstetricians and Gynecologists, Hollywood Beach, Florida, Jan. 14, 15, and 16, 1954.

This essay shows how the idea of the South Atlantic as a space of dictatorships and banana republics was contested on the ground by literary experimentation and transoceanic influence. Armillas- Tiseyra uses Sony Labou Tansi’s La vie et demie (Life and a Half 1979) as an example of a dictator novel, a genre that spans the Global South. Armillas-Tiseyra argues for the term “constellation” to be used in place of “magical realism” to classify the genre. “Constellation” here serves as a figure both for the relationship of individual texts or textual features to each other (a loose configuration or grouping) and for a mode of comparison that proceeds by juxtaposition and collage rather than more rigid hierarchical systematization. The allows Armillas-Tiseyra to approach and grapple with the difficult relationship between critique and narrative form.

AbstractThe Téfidet trough (eastern Niger) belongs to the Ténéré megasystem set of Cretaceous rifts N130°E to N170°E oriented, corresponding to the direction of the Lake Chad-Hoggar tectonic axis.The study of the relationship between the structure of the trough and alkaline fissural volcanism that developed there from the Oligocene to Plio-Quaternary shows the uniqueness of the Téfidet trough compared to the neighboring contemporary volcanic areas of Hoggar, Cameroon, and southern Aïr.The tectono-magmatic reactivation of the Cretaceous Téfidet trough developed in two steps: – a period contemporaneous with the Tuareg shield bulging (Aïr, Hoggar, Iforas);– a subsequent extension period generally N060°E, which has persisted since the opening of the South Atlantic (upper Jurassic to Plio-Quaternary).The fissural volcanism, due to the reactivation of Pan African and Cretaceous faults evolved concomitantly with the N060°E extension (syn-magmatic micro-fractures with basaltic filling), in several steps, from Oligocene to Plio-Quaternary.This study highlights the existence of periods of quietness and recovery of volcanic activity, for which two assumptions can be made: – no enough absolute datings,– apolyphased extension of the rift.The latter hypothesis seems to be supported by three periods of volcanic quietness, 28–24 m.y., 20–14 m.y. and 8–5 m.y., observed in the northern and the southern Aïr, Gréboun and Todgha, respectively.
