Summary Objective To characterize the initial events in the cleavage of type II collagen mediated by cathepsin K and demonstrate the presence of the resulting products in human and equine articular osteoarthritic cartilage. Design Equine type II coll

The authors present an inverse kinematic algorithm for a four-revolute-joint (4-R) spherical wrist that provides for a complete set of spatial orientations, is nonsingular, and is simple to implement with existing technology. The algorithm is a rate-

A graphical representation of admissible profile times for robot trajectories is presented from a kinematic perspective. Profile times are defined to be the acceleration time, slew time, and deceleration time for robot end effector motions. Given ini

A sufficient condition for the kinematic stability of a robot hybrid position/force control scheme is defined. The test for the sufficient condition is a technique that uses only the kinematic information to determine system stability or to identify

1. 1. Treatment of dilute rat thymus breis with concentrated NaCl solutions produced viscous solutions that were permanently disrupted by shearing. Attempts to measure the viscosity of such extracts in ordinary capillary viscometers were unsuccessful

Zonal centrifuges,3 developed for the mass separation of subcellular particles and viruses on the basis of either sedimentation rate or buoyant density (l-8)) have been used to isolate the major subcellular components (7), viruses (4, 5, 9, lo), ribo

1. 1. One molar NaCl extracts of rat thymus are highly sensitive to X rays, and an exposure of 10 r causes a detectable loss in viscosity. An aftereffect was observed, and the viscosity of irradiated samples continued to decrease for 4–5 hours afte
