High speed, self-acting, face-contact shaft seal has low leakage and very low wear [PDF]
, 1972 Design adds gas thrust bearing to face of conventional face seal. Bearing lifts seal's carbon face out of contact after startup and establishes thin gas film between sealing surfaces.

Finite-element analysis of contact between elastic self-affine surfaces
, 2004 Finite element methods are used to study non-adhesive, frictionless contact between elastic solids with self-affine surfaces. We find that the total contact area rises linearly with load at small loads.

Arthritis Care &Research, Accepted Article.Aims We investigated whether a diagnosis of rheumatoid arthritis (RA) affects the quality of inpatient acute myocardial infarction (AMI) care and long‐term mortality post‐AMI. Methods We analysed data from 784,091 adults, 6,047 with a diagnosis of RA, from England and Wales hospitalised with AMI between 2005 and 2019 from the MINAP registry, linked ...

Setting Process and Sealing Performance Analysis of Downhole Blowout Preventer
Shiyou jixie, 2021 The downhole blowout preventer(BOP)can be directly set on the overflow source to effectively prevent blowout from occurring. In order to study the setting process and sealing performance of downhole BOP, the ABAQUS software was used to build the finite ...

Liquid droplets on a free-standing glassy membrane: deformation through the glass transition
, 2017 In this study, micro-droplets are placed on thin, glassy, free-standing films where the Laplace pressure of the droplet deforms the free-standing film, creating a bulge. The film's tension is modulated by changing temperature continuously from well below
