Simulation of low rigidity part machining applied to thin-walled structures [PDF]

open access: yes, 2010
The aim of this study is to evaluate the modelling of machining vibrations of thin-walled aluminium work- pieces at high productivity rate. The use of numerical simulation is generally aimed at giving optimal cutting conditions for the precision and the ...

Numerical and Experimental Investigation on the Abrasive Flow Machining of Artificial Knee Joint Surface

open access: yesCrystals, 2023
The titanium alloy artificial knee joint is used extensively in the current medical industry due to its distinct characteristics and properties that are like the real human knee joint, but it does need to be polished to improve its performance and ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Experimental study of thin part vibration modes in machining [PDF]

open access: yes, 2008
The machining of thin walls generally generates milling chatter, that damage surface roughness and manufacturing tools. Stability lobes which include natural frequencies are successful in case of tool chatter.
