"This is one of the first large-scale attempts in which we can directly compare different dating approaches on the exact same stratigraphic section," Dr Duval said."The different dating methods have yielded very consistent results, giving us confidence in their robustness." Although additional dating analyses have to be carried out in the area to confirm these initial promising results, the study nevertheless strongly suggests the absence of fluvial deposits younger than 1 million years in the area.Until now, the previous geomorphological studies of the area were mostly limited by the absence of numerical dating results.The successful combination of independent dating methods such as Electron Spin Resonance, Luminescence and palaeomagnetism has helped to fill this previous gap in knowledge.At a regional scale, several indicators point to transient fluvial response resulting from major tectonic activity in this area, especially rock uplift in the Beni Snassen massif.The latter strongly influenced drainage organisation, and therefore landscape evolution, in northeast Morocco.
The translation of the Pentateuch from Hebrew into Greek was a practical necessity for the large Jewish community in Alexandria, already Hellenized by the end of the 3rd century , rendered possible in Alexandria because of the abundance of research material available at the library.
The Lower Moulouya river is the largest drainage network in Morocco.
It is located in the tectonically active convergence zone between Africa and Europe.
Recent progress in the measurement, modeling and manipulation of matter and phenomena at the scale of 1 to 100 nanometers has us on the verge of revolutionizing information processing, data storage, sensors, power generation, materials, environment, robotics and medicine.
To illustrate this scale, one nanometer is one-billionth of a meter, approximately one-thousandth the width of a human hair.
