Grand Erg Oriental only national flights. In Libya Ghadames Airport schedules only national flights.

Grand Erg Oriental The Grand Erg Oriental (English: 'Great Eastern Sand Sea') is a large "erg" or "field of sand dunes" in the Sahara Desert. Situated for the most part in Saharan lowlands of northeast Algeria, the Grand Erg Oriental covers an area some 600 km wide by 200 km north to south. The erg's northeastern edge spills over into neighbouring Tunisia. The Grand Erg
ERG (gene) in mature lymphocytes (types of white blood cells). Therefore, ERG may act as a regulator of differentiation of early hematopoietic cells. The Mld2 mutation, generated through an ENU mutagenesis screen, was the first non-functional allele of "Erg". Homozygous Mld2 is embryonic lethal at day 13.5. Adult mice heterozygous for the Mld2 mutation have hematopoietic stem cell defects. This means that when the ERG gene was not actively transcribed and the ERG protein produced, a mouse's hematopoietic cells were unable to function properly. Since ERG is important to the ability of the hematopoietic cells to function and self-renew, there may be
