Hydrodynamic air lubricated compliant surface bearing for an automotive gas turbine engine. 2: Materials and coatings [PDF]

open access: yes, 1978
Material coatings for an air-lubricated, compliant journal bearing for an automotive gas turbine engine were exposed to service test temperatures of 540 C or 650 C for 300 hours, and to 10 temperature cycles from room temperatures to the service test ...

Assessment of Skin in Patients With Systemic Sclerosis Using High‐Frequency Ultrasound and Shear Wave Elastography: A Comparative Study With Histology, Molecular, and Clinical Parameters

open access: yesArthritis Care &Research, EarlyView.
Objective Ultrasound (US) has been proposed as a potential tool for assessing skin fibrosis in systemic sclerosis (SSc). However, a large‐scale comparison of US‐based assessment with histologic markers of skin fibrosis has not been reported. We evaluated US‐based skin assessments for their face validity (differentiation between involved SSc and healthy

Resilient bearing supports are gas controlled [PDF]

open access: yes, 1967
Self-acting, partial-arc, pivoted-pad bearings in which the bearing-to-journal applied load is pneumatically controlled are used in the operation of a radial flow gas generator where shaft speeds are on the order of 38,500 ...

Performance prediction of journal bearing with fluid slip regions on part of lubricated surface

open access: yesNihon Kikai Gakkai ronbunshu
Rotating machineries supported in journal bearings are operated at a rotational speed between the one where the minimum oil film thickness is ensured to prevent direct contact of the journal and bearing surfaces and the one where self-excited vibration ...

Clinical Practice Guideline for Evaluation and Management of Peripheral Nervous System Manifestations in Sjögren's Disease

open access: yesArthritis Care &Research, Accepted Article.
Objectives Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies. To help patients and providers in the decision‐making process, we developed

Robustness of Cryogenic Hybrid Journal Bearings

open access: yesTribology Online, 2012
In the present study, a nine-recess hybrid journal bearing (HJB) having a Young Leaf Mark recess was operated at a rotational speed of up to 75,000 rpm using the cryogenic journal bearing test apparatus at JAXA, to clarify an onset speed of the rotor ...

Combining Three Peripheral Blood Biomarkers to Stratify Rheumatoid Arthritis‐Associated Interstitial Lung Disease Risk

open access: yesArthritis Care &Research, Accepted Article.
Objective The purpose was to evaluate a biomarker score consisting of MUC5B rs35705950 promoter variant, plasma matrix metalloproteinase (MMP)‐7, and serum anti‐malondialdehyde‐acetaldehyde (anti‐MAA) antibody for RA‐associated interstitial lung disease risk stratification. Methods Using a multicenter cohort of US veterans with RA, we performed a cross‐
