The response of climate to perturbations in GHGs is location dependent. Six experiments: control (CTRL); double CH4; double CO2; double N2O; halved CFC11 and halved CFC12 were carried out to reveal the local area response to different GHGs levels in the atmosphere over West Africa. Double CH4, CO2 and N2O generally induce wetness but they also induce localized dryness at the hilly and mountaino...

centuries. Starting from the pre-Islamic era in the 6th century AD and extending to the 16th Century AD when the Ottoman Sultan Salim I in 1516 AD invaded and destroyed the Mamluk Dynasty in Syria and Egypt extending the Ottoman Empire into North Africa. The language of science at the time was Arabic. Many scientists and physicians throughout the Muslim Empire taught and wrote in Arabic. This w...

The first regional topsoil sampling campaign since 2011 maps elevated background concentrations of potentially toxic elements in soils across north-west Syria following more than a decade conflict.

Introduction: Travel health practice and research in Egypt lag behind both needs and demands. This study was done in two parts to assess travel health knowledge, attitude, and practice (KAP) among Egyptian travelers. Methods: This survey was conducted at the departure halls of Cairo International Airport and included 1500 travelers to Africa (excluding No...

Based on mitochondrial 16S rRNA sequences, we suggest that the founder individuals of the introduced Greek population of Chamaeleo africanus originated in the Nile Delta region of Egypt. In Ch. chamaeleon, we discovered in the eastern Mediterranean new 16S rRNA haplotypes, being highly distinct from previously published western Mediterranean haplotypes. Eastern Mediterranean haplotypes were fou...

North African populations are distinct from sub-Saharan Africans based on cultural, linguistic, and phenotypic attributes; however, the time and the extent of genetic divergence between populations north and south of the Sahara remain poorly understood. Here, we interrogate the multilayered history of North Africa by characterizing the effect of hypothesized migrations from the Near East, Europ...

ORIGIN AND HISTORY The pistachio is native to western Asia and Asia Minor, where it is still found growing wild in numerous hot, dry locations in Lebanon, Palestine, Syria, Iran, Iraq, India, Southern Europe and the desert countries of Asia and Africa. It was introduced to Europe at the beginning of the Christian era. The first pistachio introductions to the United States were by the USDA plant...
