Investigation of Electrical Bearing Failures

, 2023
Cette étude s'intéresse à l'effet des décharges capacitives, induites par les onduleurs d'alimentation des machines électriques, sur les roulements à billes. Un banc d'essai a été construit pour générer artificiellement une rugosité du roulement par électroérosion.

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

The practical impact of elastohydrodynamic lubrication [PDF]

The use of elastohydrodynamics in the analysis of rolling element bearings is discussed. Relationships for minimum film thickness and tractive force were incorporated into computer codes and used for bearing performance prediction.

Characterising fibre compression fracture toughness of composites using bearing tests [PDF]

, 2012
In this paper we propose the use of a bearing test with a coupled experimental-numerical approach to characterise the critical strain energy release rate, or "fracture toughness", for fibre compression failure in ...

Dietary nitrate and nitrite protect against doxorubicin‐induced cardiac fibrosis and oxidative protein damage in tumor‐bearing mice

FEBS Open Bio, EarlyView.
Chemotherapies such as doxorubicin can have toxic effects on healthy cardiovascular/heart tissue. Following up on a doxorubicin toxicity study in mice without tumors where nitrate water was cardioprotective (lessened toxicity), this study with tumor‐bearing mice undergoing doxorubicin treatment showed no negative effect of nitrate and nitrite on drug ...

Life Analysis of Wear Fatigue Competition Failure Mechanism of Main Bearing of Boring Machine

Shanghai Jiaotong Daxue xuebao
The main bearing of a tunneling machine is prone to premature failure under the influence of multiple factors such as wear and fatigue during service, making it difficult to predict its lifetime.

Experimental study and numerical modelling of woven fabric kenaf fiber composites hybrid adhesively bonded-bolted joints [PDF]

, 2018
Couple with natural fiber composite parts, hybrid joints provide better joint strength than using separate joints. There are limited studies on structures response and strength prediction work on hybrid joints that limits its applicability.

Establishment of a coculture system for Porphyromonas gingivalis and head and neck squamous cell carcinoma using spheroid culture and LATS inhibition

FEBS Open Bio, EarlyView.
We established a spheroid coculture system enabling viable Porphyromonas gingivalis–HNSCC interactions under normoxic conditions. Inhibition of LATS1/2 maintains tumor cells in an undifferentiated state, which may promote spheroid growth and create a more permissive environment for bacterial persistence.
