Genomic tools and analyses are now being widely used to understand genome-wide patterns and processes associated with speciation and adaptation. In this article, we apply a genomics approach to the model organism Drosophila melanogaster. This species originated in Africa and subsequently spread and adapted to temperate environments of Eurasia and the New World, leading some populations to evolv...
Sequencing of 81 entire human mitochondrial DNAs (mtDNAs) belonging to haplogroups M1 and U6 reveals that these predominantly North African clades arose in southwestern Asia and moved together to Africa about 40,000 to 45,000 years ago. Their arrival temporally overlaps with the event(s) that led to the peopling of Europe by modern humans and was most likely the result of the same change in cli...
OBJECTIVE Middle Eastern and North African countries are undergoing nutrition transition, a transition which is associated with an increased burden of non-communicable diseases. This necessitates the evaluation of dietary patterns in these regions. The present study aimed to assess changes in dietary patterns in Middle Eastern and North African countries between 1961 and 2007. DESIGN Availabi...
This paper briefly analyses the requirements for “share and reuse” of learning objects in Middle East and North Africa. We propose a framework that can be used to connect Learning Object Repositories of the Middle East and North Africa with networks of repositories worldwide; through the services of the ARIADNE Foundation (http://www.ariadne-eu.org/) and the GLOBE consortium (http://globe-info....
Among the countries that can be classified as Near East Africa, North West Africa, and Western Africa, there is a great diversity of foods and dietary patterns. Prevalence of undernourishment as defined by FAO using dietary energy supply data, varies dramatically among these countries, with Tunisia in the lowest prevalence category (<2.5%), and Sierra Leone in the highest prevalence category (>...
The conflict in Syria has created the largest humanitarian crisis in decades. As the fifth year of the Syria crisis begins, the humanitarian needs across the region stretch beyond description. Constant, deadly conflict is destroying lives, families and communities. Today, hardly a family remains in Syria unaffected by the catastrophe. Well over one third of Syria’s pre-conflict population of 22...
the occurrence of dust storms and their sources in the southern and central parts of iran during the period of 2002 to 2009 was investigated. for this purpose, the meteorological and synoptic data, data from the middle and upper atmosphere, and wind flow tracking model were used. dust storms and nddi were traced using satellite imagery from fasa, shiraz, and bushehr stations. analysis of the gr...
