Regional view of a Trans-African Drainage System

Despite the arid to hyperarid climate of the Great Sahara of North Africa, pluvial climates dominated the region. Radar data shed some light on the postulated Trans-African Drainage System and its relationship to active and inactive tributaries of the Nile basin. Interpretations of recent elevation data confirm a source of the river water from the Red Sea highlands did not connect the Atlantic ...

Blood samples obtained from the coronary sinus in man contain venous blood draining from left ventricular myocardium. It is believed by many investigators that coronary sinus blood in man is composed almost entirely of left ventricular efflux. That this is true in the canine heart is firmly established (Rayford et al., 1959). This principle has been widely accepted in the many studies which hav...
