The genus Micatagla Argaman (Bradynobaenidae: Apterogyninae) is reviewed from Egypt, based on specimens collected from Wadi Allaqi (Aswan, Southern Egypt) and Kom Osheim (Fayoum) and those deposited in Egyptian insect collections as well as recorded data from the literature. A single species, Micatagla klugi (André), was previously recorded from Egypt. Micatagla allaqiensis sp. n., Micatagla ez...

An Egyptian fraction is a sum of reciprocals of distinct positive integers, so called because the ancient Egyptians represented rational numbers in that way. In an earlier paper, the author [8] showed that every positive rational number r has Egyptian fraction representations where the number of terms is of the same order of magnitude as the largest denominator. More precisely, there exists a p...

Here we present a new approach to archaeological reconstruction, in which we project digitally reconstructed iconography within a damaged Egyptian tomb. Combining video projection, computer animation, and digital compositing, a kind of ‘plural space’ is generated in the tomb’s burial chamber; this work is designed to enable visitors to view elements that were destroyed in antiquity. Also, we su...

Chemical analyses of ancient organics absorbed into pottery jars from the beginning of advanced ancient Egyptian culture, ca. 3150 B.C., and continuing for millennia have revealed that a range of natural products--specifically, herbs and tree resins--were dispensed by grape wine. These findings provide chemical evidence for ancient Egyptian organic medicinal remedies, previously only ambiguousl...

In 1947, Egyptian novelist, short story writer and playwright Mahmud Taymur (1894-1973) was awarded the first prize in short story writing from Cairo Arabic Language Academy. Two years later, Taymur was made a member of the prestigious scholarly institution whose main mission was to promote and defend the use of classical Arabic in modern Arabic literature. In both the statement made by the jur...

We consider the problem of determining if two finite groups are isomorphic. The groups are assumed to be represented by their multiplication tables. We present an O(n) algorithm that determines if two Abelian groups with n elements each are isomorphic. This improves upon the previous upper bound of O(n log n) [23] known for this problem. We solve a more general problem of computing the orders o...

The present study has examined the similarity and the mutual intelligibility between Amharic and two Tigrigna varities using three tools; namely Levenshtein distance, intelligibility test and questionnaires. The study has shown that both Tigrigna varieties have almost equal phonetic and lexical distances from Amharic. The study also indicated that Amharic speakers understand less than 50% of th...

INTRODUCTION An estimated 17% of married women in the developing world still have an unmet need for contraception. This study aimed to measure the prevalence and reasons for unmet contraceptive need among married women in the childbearing period in an underprivileged district in Eastern Cairo. METHODS A cluster survey of 2340 women in the Marg district of Eastern Cairo was performed. Socio-de...
