Recent results by Wearne [(1993) Ph.D. thesis] using the scleral search-coil method of measuring eye position indicate that changes in ocular torsion position (OTP) occur during yaw angular acceleration about an earth vertical axis. The present set of experiments, using an image processing method of eye movement measurement free from the possible confound of search coil slippage, demonstrates t...

BACKGROUND In recent years, there has been a great interest in analyzing upper-limb kinematics. Inertial measurement with mobile phones is a convenient and portable analysis method for studying humerus kinematics in terms of angular mobility and linear acceleration. OBJECTIVE The aim of this analysis was to study upper-limb kinematics via mobile phones through six physical properties that cor...

Real-time monitoring of the translation of non-capped luciferase mRNA in a wheat germ cell-free system has been performed by continuous in situ measurement of the luminescence increase in the translation mixture. The phenomenon of acceleration of translation has been revealed. It has been shown that the acceleration is accompanied by the loading of translating polysomes with additional ribosome...

A test method based upon a Hybrid-III head and neck assembly that includes measurement of both linear and angular acceleration is investigated for potential use in impact testing of protective headgear. The test apparatus is based upon a twin wire drop test system modified with the head/neck assembly and associated flyarm components. This study represents a preliminary assessment of the test ap...
