Evaluation of journal bearings characteristics using finite element method

, 2010
Dynamic behavior of the rotor-bearings system exerts a considerableinfluence on rotating machine operating and stability. Indeed, vibrations insuch machines may cause not only high level of noise but also wearing ofmoving components. Hydrodynamic journal

Determining the Minimal Clinically Important Difference of the 40‐Item Smell Identification Test in People With Cystic Fibrosis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) and olfactory dysfunction (OD) are highly prevalent among people with cystic fibrosis (PwCF) and negatively impact quality of life. The 40‐item Smell Identification Test (SIT) is widely used to assess psychophysical olfaction, but a CF‐specific minimal clinically important difference (MCID) has not been ...

Early Failure Detection and Diagnostics of High Speed Self Aligning Journal Bearing

Because of their high load carrying capacity and low cost, journal bearings are widely used to support the rotor of industrial machinery with high loads, such as steam turbines, centrifugal compressors and pumps.

Quantum Phenomena in Molecular and Biological Systems: A Decoherence‐Based Decision Framework With Falsifiable Predictions and a Failure‐Mode Taxonomy

Advanced Physics Research, EarlyView.
A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...

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.

Analysis of Elasto-hydrodynamic Lubrication Characteristics of Journal Bearings Under Starved Lubrication

Jixie chuandong
With the gradual increasing of wind turbine power, the advantages of journal bearings in wind turbine gearboxes are gradually prominent. When the lubrication system is blocked or the oil supply is insufficient, the journal bearing will be in the starved ...
