A Comparison of Averaged and Full Models to Study the Third-Body Perturbation [PDF]
The Scientific World Journal, 2013 The effects of a third-body travelling in a circular orbit around a main body on a massless satellite that is orbiting the same main body are studied under two averaged models, single and double, where expansions of the disturbing function are made, and ...

Third body damage and wear in arthroplasty bearing materials: A review of laboratory methods [PDF]
Biomaterials and Biosystems, 2021 Third body wear of arthroplasty bearing materials can occur when hard particles such as bone, bone cement or metal particles become trapped between the articulating surfaces. This can accelerate overall implant wear, potentially leading to early failure.

VIEW Journal of European Television History and Culture, 2015 Emerging in the UK in the 1980s, Scratch Video established a paradoxical union of mass-media critique, Left-wing politics, and music-video and advertising aesthetics with its use of moving-image appropriation in the medium of videotape.

Ultrasound gel minimizes third body debris with partial hardware removal in joint arthroplasty [PDF]
Arthroplasty Today, 2017 Hundreds of thousands of revision surgeries for hip, knee, and shoulder joint arthroplasties are now performed worldwide annually. Partial removal of hardware during some types of revision surgeries may create significant amounts of third body metal ...

Third Body Wear of an All-Polymer, PEEK-OPTIMA™ on Ultra-High-Molecular-Weight Polyethylene Total Knee Replacement [PDF]
BioengineeringExperimental wear simulation of a PEEK-OPTIMA™ polymer-on-UHMWPE total knee replacement has shown equivalent UHMWPE wear to conventional knee replacement materials (cobalt chrome-on-UHMWPE) when tested in a clean environment. The aim of this study was to

Mechanochemical Friction of Third-Body as an Exergetic Collision
Tribology Online, 2011 Approximation of a third body proposes that a tribo-contact is conformed by two first bodies (that is to say; elements of a machine), and by an interface -or third body- of different composition, where velocity between the first two bodies accommodates ...

Running-In of DLC–Third Body or Transfer Film Formation
LubricantsAmorphous carbon coatings are widely used due to their beneficial friction and wear characteristics. A detailed understanding of their behavior during running-in, apart from model tribosystems, has yet to be obtained.

Third Body Wear of UHMWPE-on-PEEK-OPTIMA™. [PDF]
Materials (Basel), 2020 PEEK-OPTIMA™ is being considered as an alternative to cobalt chrome (CoCr) in the femoral component of total knee replacements. To date, investigations of ultra-high molecular weight polyethylene (UHMWPE)-on-PEEK have shown an equivalent wear rate to conventional implant materials under standard conditions.

Roughness Evolution Induced by Third-Body Wear. [PDF]
Tribol LettAbstractSurface roughness is a key factor when it comes to friction and wear, as well as to other physical properties. These phenomena are controlled by mechanisms acting at small scales, in which the topography of apparently flat surfaces is revealed.

CCD Photometric Observations and Light Curve Synthesis of the Near-Contact Binary XZ Canis Minoris [PDF]
Journal of Astronomy and Space Sciences, 2009 Through the photometric observations of the near-contact binary, XZ CMi, new BV light curves were secured and seven times of minimum light were determined.
