Clearance of proteoglycan from joint cavities. [PDF]
Annals of the Rheumatic Diseases, 1987 The rate of loss from the synovial cavity of proteoglycan subunit, a major constituent of cartilage, has been measured in rabbits with and without experimental arthritis. The effect of aggregation between proteoglycan and hyaluronic acid upon the rate of elimination has also been investigated.

Nonlinear Characteristics of Revolute Joints with Clearance
Journal of Aerospace Technology and Management, 2013 http://dx.doi.org/10.5028/jatm.v5i3.236 The nonlinear contact characteristic of revolute joint with clearance can degrade the performance of deployable structure. In this article, tensile and compressive tests are adopted to investigate the accuracies of the simplest conformal model and nonconformal model for contact, which are used to calculate the ...
