Mamluk administration in Aleppo in the ninth century AH / fifteenth century AD (the case of Banu Saffah)

Aleppo has enjoyed great importance in the age of the Mamluk Empirecircassian because of the importance of its geographical location on the northern border of the state Mamluk. Aleppo was an administrative point of central authority in the city of Cairo. This study aims to demonstrate the military and civilian administrative functions, which are found in the city, and groups that have held these jobs. In addition to addressing possible means in order to get, a job in this age.

Use of the time-temperature arrhenius index in evaluation the maturity of the organic matter in Siluric and upper Paleozoic rocks in the central and eastern parts of the Aleppo Plateau

considering the importance of temperature and time factors in maturation and conversion the organic materials ,and the facts, that the sum of the effects of these factors is effected by the sedimentary burial history and changes with the changing of the kerogen types,and for consummation the aim of this study in isolating the Siluric and upper Paleozoic rock formations in which temperature and time had allowed to their included organic material to realise its potential in conversion to hydrocarbonic materials, paleotictonic and geotemperature diagrams for these formations were drawn depending on real data from 12 selected drilled wells in the study area, then the values of timetemperature Arrhenius index and the percent of the realised potential in conversion to hydrocarbonic materials were calculated for each main kerogen type (Ia,b,c, II,a,b,c,d, III) which may undergo to the same time-temperature history of the studied formations.
