Rheopexy and tunable yield stress of carbon black suspensions [PDF]

open access: yes, 2012
We show that besides simple or thixotropic yield stress fluids there exists a third class of yield stress fluids. This is illustrated through the rheological behavior of a carbon black suspension, which is shown to exhibit a viscosity bifurcation effect ...

Stress Exponent of Minimum Creep Rate and Activation Energy of Creep for Oxide Dispersion-strengthened Nickel-based Superalloy MA754

open access: yesISIJ International, 2012
The stress exponent of the minimum creep rate, n, and the activation energy of creep, Qc, were obtained for the oxide dispersion-strengthened nickel-based superalloy MA754 by conducting creep tests at 1223–1273 K in the stress range of 130–190 MPa. The values of n and Qc in MA754 were determined to be 26 and 962 kJ/mol, respectively.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

DEFORMATION-MECHANISM-BASED MODELING OF CREEP BEHAVIOR OF P91 STEEL

open access: yesJixie qiangdu, 2022
Creep behavior of P91 steel was studied by using a constitutive model based on deformation mechanism. Combined with the experimental data, it was found that the minimum creep rate has an obvious exponential relationship with the applied stress during ...

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

A simplified creep-reverse plasticity solution method for bodies subjected to cyclic loading [PDF]

open access: yes, 2004
An extension of the upper bound shakedown theorem to load histories in excess of shakedown has been applied recently to the evaluation of a ratchet limit and the varying plastic strain magnitudes associated with a varying residual stress field. Solutions

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

open access: yesMolecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

INVESTIGASI LAJU REGANGAN CREEP BAJA TAHAN KARAT FERRITIC PADA TEMPERATUR 570 °C

open access: yesRekayasa Mesin
The probabilistic assessment of failure due to the creep phenomenon must be determined with the minimum deviation. Since the creep failure took years before rupture, laboratory experiments were conducted to represent the failure time.

Constant load creep data in air and vacuum on 2.25Cr-1Mo steel from 600 °C to 700 °C

open access: yesMaterials Research, 2005
Creep results on 2.25Cr-1Mo were obtained at 600 °C, 650 °C and 700 °C at five stress levels, under constant load, in air and vacuum. Two chambers were specially developed for carrying out creep testing in controlled environment, with the ...
