The apparatus used in the experiment which is the subject of this communication is related to that named after Puccianti.' It consists essentially of identical tubes about 85 cm. long with optically plane parallel ends placed in the arms of an interferometer and filled to the same pressure with hydrogen. A powerful discharge was passed through one of the tubes while "white-light" fringes from a...

BACKGROUND The objective of this study is to evaluate the force-deflection behavior of beta-titanium alloy wires between two leveled and unleveled bracket alignment scenarios using a three-point bending test. METHODS Six groups of ten beta-titanium alloy wire segments (0.017 × 0.025-in. diameter) of different manufacturers (Orthometric, Ortho Organizers, GAC, Morelli, and Ormco) were used. Bo...

To monitor the beam profile in injector of BEPCII which is the upgrade project of Beijing Electron Positron Collider (BEPC). Several beam diagnostic and monitoring instruments are used. Wire scanner as a new diagnostic instrument was designed and manufactured to measure the beam profile at the end of linac in 2007.During the shutdown period of BEPCII we had installed the system at the end of li...

FUCHS, ALBERT F., AND DAVID A. ROBINSON. A method for measuring horizontal and vertical eye movement chronically in the monkey. J. Appl. Physiol. 21(s) : 1068-1070. I g66.-Eye movements are measured chronically in the monkey by surgically implanting a coil of fine wire upon the eyeball beneath the bulbar conjunctiva and recti insertions. The ends of the coil are led to a connector mounted on th...
