Microstructural modelling of creep crack growth from a blunted crack [PDF]

, 1998
The effect of crack tip blunting on the initial stages of creep crack growth is investigated by means of a planar microstructural model in which grains are represented discretely. The actual linking-up process of discrete microcracks with the macroscopic

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Evaluation of surface response of SiC and fly ash-filled Prosopis juliflora fibre-reinforced epoxy composites under dry sliding wear conditions using Taguchi method

Journal of Engineering and Applied Science
Prosopis juliflora (PJ) fibre-reinforced polymer composites are fabricated with fly ash and SiC as fillers with different weight percentages. Jute layers are also sandwiched for added strength in the structure.

Experimental Study on Dry Friction Behavior of AlumiNm Alloy Casing

Shiyou jixie, 2022
In order to study the frictional and wear behavior of alumiNm alloy casing in gas drilling technology, under dry friction conditions, taking 40CrNmo steel as the pin and 7075 alumiNm alloy as the disc, by means of pin-disc wear test system, the effects ...

Friction and wear behaviors of biodegradable Mg-6Gd-0.5Zn-0.4Zr alloy under simulated body fluid condition

Journal of Magnesium and Alloys, 2017
The friction and wear behaviors of biodegradable Mg-6Gd-0.5Zn-0.4Zr (wt%, GZ60K) alloy were evaluated under simulated body fluid (SBF) condition using ball-on-disk configuration and compared with those under dry sliding condition.

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

FEBS 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 ...

Sliding Mode Flow Rate Observer Design [PDF]

, 2008
Dynamic flow rate information is needed in a lot of applications; however it is normally not measurable. Calculation of the flow rate from fluid pressure dynamic equations usually results in poor estimates due to the very noisy pressure measurements and ...
