We present a new feasible theory about how the ancient Egyptians moved and lifted heavy stones and how they built the Great Pyramid of Giza around 2500 BC, from the viewpoint of energy management taking account of the vast quantity of the stones needed for the Pyramid. We give our solutions to the following three mysteries of the Pyramid: 1) How they could overcome the difficulty in making the four straight edges of the Pyramid meet in one point, high up in the sky? 2) Why all of chambers and passages (the King's and the Queen's chambers, the Grand Gallery and other passages), except the Subterranean chamber, are away from the central axis about seven meters eastwards? 3) For what purpose they dug the Subterranean Chamber, thirty meters deep?

An entirely new feasible theory is presented about how they constructed, moved, shaped, and erected obelisks in ancient Egypt around 1500 BC. In particular, we propose two simple ways to erect obelisks, inspired by the historical fact that all of obelisks were originally erected "in pairs," except the single "Lateran" obelisk. Our aim is to "excavate" ancient Egyptian methods to raise heavy high obelisks, using only the most primitive means including forerunners of pulley, but excluding further mechanical devices, like capstan or winch, which were employed in most cases of re-erection and re-location of obelisk outside of Egypt.

stiffness and pulse wave velocity / Aorta and carotid arteries 137 (0.94 to 1.01) p = 0.096; Obesity OR = 0.47 (0.29 to 1.77) p = 0.003 and Diabetes OR = 2.41 (1.15 -5.05) p = 0.020. Conclusions: According to the results obtained, genetic polymorphisms variables were not in the multivariate analysis equation to determine the increase of the PWV, which can be explained either by being included in the selected variables such as hypertension, or on the other hand, they may not have enough strength to remain in the equation. So, according to this study, PWV has much more to do with behaviors and traditional risk factors than the genetic heritage.P883 Endothelial dysfunction, pulse wave velocity and augmentation index are correlated in subjects with systemic arterial hypertension?

The Great Pyramid has the character of concavity that each of its four faces is slightly indented along its central line. Applying the geometry on an inclined plane, we show that this concavity could be derived from its inner structure of inward sloping courses gently inclined towards the center of each course, at about 11 degrees to the horizontal, i.e., the slope 1/5 by the ratio of "rise over run". We explain why the inclined layers together with the reinforced base were necessary for the long-term stability of the Pyramid against the severe natural forces like the high gravitational compression, earthquakes and rainstorms, pointing out the feasible fact that the Pyramid has experienced severe rainstorms more than 500 times during the 4500 years. The crucial point about stability is that the effects of such natural forces are quite different between the core of inclined courses and that of truly level courses in the sense that the former can be tightened to become stronger over time, but the latter would be disintegrated to be weaker over time. Scaled-down models of the Pyramid are introduced to understand the large-scale dynamics of the Pyramid. In particular, the small model reduced by 10 −3 helps us to imagine the transformation of vertical into lateral forces, pointed out by Mendelssohn. On the other hand, the Step Pyramid of Djoser can be identified almost as the half-sized model of the Great Pyramid when the Great Pyramid was assumed to be composed only of truly level courses. And this identification tells the fate of the Great Pyramid only of truly level courses that it would have almost collapsed until now like the Step Pyramid before the recent restoration.

The true purpose of a wooden "rocker" from a foundation deposit in the tomb of Queen Hatshepsut at Dier el-Bahri is proposed that it was an open mould for a mudbrick or concrete rocker. The solid rockers produced by such a mould have grooves that act as rope channels so that they can be attached to a stone (or sledge under the stone) by ropes to roll or turn the stone easily. We proposed how the wooden rocker could be used to produce solid rockers, then tested this method experimentally to get mudbrick or concrete rockers with grooves.
