Magnetohydrodynamic Journal Bearing (Report 1)

, 1969
A theoretical analysis of an infinite full journal bearing is presented for the case of an electrically conducting fluid in the presence of a radial magnetic field. The analysis is based on general external loading conditions.

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

The Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

An Investigation of Surface Vibration, Airbourne Sound and Acoustic Emission Characteristics of a Journal Bearing for Early Fault Detection and Diagnosis

High power machinery such as steam turbines, large pumps and motors often use journal bearings as rotor supports. This type of bearing is simple, low cost and with high load carrying capacity.

Partial Repair and Superior Capsular Reconstruction Both Improve Outcomes for Irreparable Posterosuperior Rotator Cuff Tears: A Systematic Review

Arthroscopy, EarlyView.
Purpose To synthesize patient‐reported outcome measures, failure rates, and mobility parameters for comparison of partial repair versus superior capsular reconstruction (SCR) in the treatment of irreparable posterosuperior rotator cuff tears. Methods EMBASE, OVID Medline, and Emcare were searched from database inception to November 2024 for studies on ...

Study of two‐lobe four recessed hybrid journal bearing

, 2010
PurposeIn recent years, researchers have focused a great deal of attention on multirecess hybrid journal bearing systems. The non‐circular journal bearings are widely used in industry on account of their better stability, simplicity, efficiency and low ...

Excellent Outcomes and High Rates of Return to Duty but a 10% Chance of Tear Progression Are Seen Following Arthroscopic Debridement Alongside Adjunctive Procedures for Articular‐Sided, Partial‐Thickness Supraspinatus Tears (Ellman Grade I) in Active‐Duty Service Members Younger Than 50 Years

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate clinical outcomes and return‐to‐duty rates in active‐duty service members younger than 50 years after arthroscopic debridement of Ellman grade I, articular‐sided partial‐thickness rotator cuff tears (PT‐RCTs) of the supraspinatus.

The Presence of Chondral Pathology Is Not Associated With an Increase in Meniscal Root Retear, Reoperation, or Subsequent Total Knee Arthroplasty Rates

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To identify whether chondral pathology is associated with an increase in failure rates of isolated meniscal root repairs. Methods We retrospectively reviewed meniscus repairs from 2012 to 2022 at the author's institution. Nonroot repairs and cases with total or same compartment meniscectomy, cartilage restoration, osteotomy, or other concurrent
