Radiation exposure to staff members during traction X-rays

Background Determining the flexibility of a scoliosis curve is important, during both conservative and surgical management, and traction x-rays of the patient’s spine are frequently done as part of this evaluation. The traction x-ray is done with the patient in the supine position, and with staff members pulling on the patient’s arms and legs. The use of staff to produce the traction radiograph...

بررسی فازی ترکیبات Mo + 2(1 - x) Si + 2xAl

X-ray powder diffraction data for Mo2.85Al1.91Si4.81 are presented here. The new Mo2.85Al1.91Si4.81 compound was successfully prepared, using the self-propagating high-temperature synthesis (SHS) technique. The starting atomic mixture of reactant powders was Mo + 2(1 - x)Si + 2xAl with 0.2 ≤ x ≤ 0.5. The final powder compound obtained by the SHS technique was determined to be in x = 0.2; Mo(Si,...

A Note on Twists of (y^2=x^3+1)

‎‎In the category of Mordell curves (E_D:y^2=x^3+D) with nontrivial torsion groups we find curves of the generic rank two as quadratic twists of (E_1), ‎and of the generic rank at least two and at least three as cubic twists of (E_1). ‎Previous work‎, ‎in the category of Mordell curves with trivial torsion groups‎, ‎has found infinitely many elliptic curves with ...
