On the constitutive equations of fresh mortar

Journal of the Mechanical Behavior of Materials, 2016
A preliminary constitutive model is suggested for fresh mortar by taking into account the rheological properties of the base matrix (concrete matrix), as well as the interaction of the aggregates (concrete suspensions).

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Thermodiffusion in Elastic Materials of Grade Two

Engineering Transactions, 1979
The elastic solid of grade two subjected to the process of thermodiffusion is studied in the framework of the nonlinear mechanics of continua. Two independent sets of constitutive quantities are obtained: the first set results from the free energy ...

Prediction of High Temperature Flow Stress of Alloy 2618-Ti during Hot Deformation

High Temperature Materials and Processes, 2015
In order to find material parameters of established Zener-Hollomon constitutive equations and predict high-temperature flow stress of alloy 2618-Ti, the hot compressive deformation behaviors of the alloy were investigated at temperatures ranging from 300

Two-dimensional Nye figures for hemitropic micropolar elastic solids [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика
The paper is devoted to a wide range of problems related to the two-dimensional Nye figures for micropolar continua. The method of two-dimensional matrix representation of fourth-rank tensors is well known from monographs on crystallography.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.
