A Source Book in Medieval Science - Volumul 1 - Pagina 459
The center of the deferent also moves at the same rate upon the small circumference in such a way that it describes equal arcs upon the equant in equal times, thus describing unequal arcs upon the small circumference. Thus, when it has ...

Sturkie's Avian Physiology - Pagina 600
The tortuous epididymal and deferent ducts are characterized by low mucosal folds covered with nonciliated pseudostratified columnar epithelial cells (Tingari, 1971; Aire, 1979a; Bakst, 1980). Based upon histological and morphological ...

Planets, Stars, and Orbs: The Medieval Cosmos, 1200-1687
D'Ailly describes the epicycle as "a small circle on the surface of the deferent orb that does not contain within itself the center of the world; and the body of the planet is imagined to be in it. And this epicycle is assumed to be contiguous, and not ...

From such things one ought to know that the distance between the center of the deferent and the center of the equant must be the same a* the distance between (fol. 65r) the fixed and the moving center of the epicycle. Moreover, one ought to ...

The epicycle-deferent system is intended to explain only motion with respect to the sphere of the stars. Both the epicycle and the deferent in Figure 19a are drawn on the plane of the ecliptic, so that the rotation of the stellar sphere carries the ...

have assumed that the deferent spoke rotated about the centre of the deferent with uniform angular speed corresponding to this period. As he also knew the time at which the guide point occupied the position D, he could then calculate its ...
