The tertiary creep of polycrystalline ice: experimental evidence for stress-dependent levels of strain-rate enhancement

open access: yes, 2012
Laboratory creep deformation experiments have been conducted on initially isotropic laboratory-made samples of polycrystalline ice. Steady-state tertiary creep rates, ∈·ter, were determined at strains exceeding 10% in either uniaxial-compression or ...

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

open access: yesFEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Cyclic J integral using linear matching method

open access: yes, 2012
The extended version of the latest Linear Matching Method (LMM) has the capability to evaluate the stable cyclic response, which produces cyclic stresses, residual stresses and plastic strain ranges for the low cycle fatigue assessment with cyclic load ...

A Flow Potential Function for Hyperbolic Sine Creep

open access: yes, 1978
A new flow potential function or yield surface is presented. This function produces the hyperbolic sine law relating stress to minimum creep rate for creep tests in uniaxial tension.

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

open access: yesFEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Assessment of alloy 709 accelerated creep properties for use in sodium cooled fast reactors

open access: yes, 2020
Includes bibliographical references.2020 Summer.The high temperature mechanical properties and microstructural development of Alloy 709 were investigated from temperatures ranging from 550 to 650 °C. Constant load creep, stress dip, and stress relaxation

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

open access: yesFEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

Transient creep modeling based on the dependence of the activation energy on the internal stress

open access: yes, 2012
Although primary stage is often neglected in creep design, in several alloys for high temperature applications, most of the allowable design strain can occurs before reaching the minimum creep rate.

Creep behavior of Mg–11Y–5Gd–2Zn–0.5Zr (wt.%) at 573K

open access: yes, 2012
The effect of microstructure on the tensile-creep behavior of Mg-11Y-5Gd-2Zn-0.5Zr (wt.%) (WGZ1152) at 573K (0.64T m) and stresses between 30MPa and 140MPa was investigated.
