Kinematic Characteristic Analysis of Hypoid Gear based on Two Kinds of Eigenfunction

open access: yesJixie chuandong, 2021
Based on the classical space meshing theory, two kinds of basic eigenfunctions and eigenvectors of conjugate surfaces are defined. The function of the two kinds of eigenfunctions in the analysis of the meshing characteristics of conjugate surfaces is ...

Shear Stress Analysis of EHL Oil Films Based on Thermal EHL Theory - Effect of Inlet Oil Temperature -

open access: yesTribology Online, 2008
Under the same EHL contact conditions as in the traction experiments carried out by Wedeven et al., the authors performed a non-Newtonian thermal EHL analysis.

Effect of moisture content on some physical properties of Canarium schweinfurthii Engl. fruits

open access: yesResearch in Agricultural Engineering, 2016
The effect of moisture content on some physical properties of three varieties of Canarium schweinfurthii Engl. fruits (small, large and long) was studied at 40.91%, 34.92%, 23.44%, 18.5% and 11.03% moisture content on wet basis in order to solve problems

Lubricant film formation in rough surface non-conformal conjunctions subjected to GPa pressures and high slide-to-roll ratios

open access: yesScientific Reports, 2020
A ball-on-disc machine was employed in a highly idealised setting to study the interplay between oil film formation and surface irregularities in single-sided rough elasto-hydrodynamic lubricated (EHL) conjunctions.

The Influence of Slide–Roll Ratio on the Extent of Micropitting Damage in Rolling–Sliding Contacts Pertinent to Gear Applications [PDF]

open access: yesTribology Letters, 2019
Micropitting is a type of surface damage that occurs in rolling–sliding contacts operating under thin oil film, mixed lubrication conditions, such as those formed between meshing gear teeth. Like the more widely studied pitting damage, micropitting is caused by the general mechanism of rolling contact fatigue but, in contrast to pitting, it manifests ...

Direct forward gravure coating on unsupported web [PDF]

open access: yes, 1998
YesThis experimental study of forward gravure coating considers the effects of operating variables on air entrainment, ribbing instabilities and the thickness of the film formed.

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

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 ...
