Analysis of Factors Affecting Lubrication Performance of Crankshaft Main Bearing Considering Thermal Effect

open access: yesJixie chuandong, 2022
In view of the factors affecting the lubrication performance of crankshaft main bearing, an elastohydrodynamic lubrication model of crankshaft main bearing, considering thermal effect, is established. The model takes the external load of bearing, bearing

Relationship between Supplied Oil Flow Rates and Oil Film Thicknesses under Starved Elastohydrodynamic Lubrication

open access: yesLubricants, 2015
Many studies have already considered starved lubrication. However, there have been no reports on the oil film thicknesses under steady starved EHL (elastohydrodynamic lubrication), where the ultra-low volume of oil supplied per unit time is uniform.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

ANALYSIS OF LOAD CAPACITY AND TEMPERATURE FIELD OF SPHERICAL HYBRID SLIDING BEARINGS (MT)

open access: yesJixie qiangdu, 2023
The oil film temperature of the spherical hybrid sliding bearings would increase due to the friction and shear of the lubricating oil at high speed or super high speed, which leads to the thermal deformation of bearing and rotor.

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

open access: yesFEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

INFLUENCE OF LOAD AND SPEED CHANGE ON LUBRICATION PERFORMANCE OF LOW SPEED HEAVY DUTY BEARINGS

open access: yesJixie qiangdu, 2019
In order to study the lubricating property of low-speed heavy-duty bearing under the condition of different loads and speed, such as the oil film thickness, oil film pressure and changes of oil film velocity. Building model of fluid-structure interaction

Comparative Analysis of Temperature Rising Characteristics of Hydrostatic Bearing Oil Film with Different Cavity Structures

open access: yesJournal of Harbin University of Science and Technology, 2018
The temperature rise in the clearance oil film of the hydrostatic bearing is the main factor for the deformation of bearing body. In order to study the temperature rising characteristics of hydrostatic bearing oil film under different cavity structure ...

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

open access: yesFEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...
