In the last decade, increasing and develop of the scientific discipline such as science, engineering and medicine was considerable. With respect to this point of view, nowadays, comparative and interdisciplinary disciplines are also collaborated to each other. Archaeological investigations followed by related scientific methods would try to get answer to the problems which were mentioned by arc...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...

This study uses remote sensing techniques to study ahu (monumental ceremonial platforms) on the island of Rapa Nui (Easter Island). The first phase of the project used commercial satellite images to locate ahu and create a comprehensive GIS database to be corroborated during future ground survey. To supplement the satellite images, a second phase of the study evaluated kite photography a low-co...
The origin of maize (Zea mays mays) in the US Southwest remains contentious, with conflicting archaeological data supporting either coastal(1-4) or highland(5,6) routes of diffusion of maize into the United States. Furthermore, the genetics of adaptation to the new environmental and cultural context of the Southwest is largely uncharacterized(7). To address these issues, we compared nuclear DNA...
