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 ...

Does Long‐Term Lower Extremity Strength Training in Adults With Knee Osteoarthritis and Varus Alignment Reduce Knee Joint Loading During Gait?

Arthritis Care &Research, EarlyView.
Objective We examined whether 18 months of strength training in individuals with knee varus alignment and medial tibiofemoral osteoarthritis (OA) reduced knee joint loads during walking compared to an attention control group. Methods This study was a secondary analysis of a randomized clinical trial that compared the effects of strength training to a ...

Pain and Patient‐Reported Physical Function Did Not Differ Among Body Composition Profiles in Patients With Hip Osteoarthritis

Arthritis Care &Research, EarlyView.
Objective To explore whether higher body fat and lower lean mass are associated with greater pain and worse patient‐reported physical function in individuals with hip osteoarthritis (OA). A secondary aim was to examine whether pain and patient‐reported physical function differ according to four body composition profiles: high body fat, low lean mass ...

Effect of hydrostatic pressure on the tribological behavior and mechanism of the multilayered graphite like-carbon (GLC) coating

Friction
In this study, the tribological behavior and mechanism of multilayered graphite-like carbon (GLC) coatings under different hydrostatic pressures (0.1–60 MPa) were investigated via a simulated deep-sea friction and wear test system.

Finite Element Investigation of Patellofemoral Contact Mechanics: Influence of Tibial Tuberosity Lateralisation and Trochlear Dysplasia on Extensor Mechanism Stability

Life
Background: Patellofemoral instability arises from the interplay between trochlear morphology and malalignment of the extensor vector. Although each factor is individually well described, their combined mechanical effects have not been quantified within ...

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.
