High strain rate behaviour of polypropylene microfoams

EPJ Web of Conferences, 2012
Microcellular materials such as polypropylene foams are often used in protective applications and passive safety for packaging (electronic components, aeronautical structures, food, etc.) or personal safety (helmets, knee-pads, etc.).

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Strain-Rate and Stress-Rate Models of Nonlinear Viscoelastic Materials

Mathematics
The paper is devoted to the modeling of nonlinear viscoelastic materials. The constitutive equations are considered in differential form via relations between strain, stress, and their derivatives in the Lagrangian description.

Use of strain, strain rate, tissue velocity imaging, and endothelial function for early detection of cardiovascular involvement in patients with beta-thalassemia

Annals of Pediatric Cardiology, 2017
Background: Global ventricular function often remains normal in patients with beta-thalassemia major. (β-TM) until late. Tissue Doppler and strain imaging may be useful to assess regional myocardial function abnormalities in these patients.

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Strain and strain rate echocardiography in children with Wilson’s disease [PDF]

Cardiovascular Journal of Africa, 2016
This study aimed to evaluate strain and strain rate echocardiography in children with Wilson's disease to detect early cardiac dysfunction.In this study, 21 patients with Wilson's disease and a control group of 20 age- and gender-matched healthy children were included.

Evaluation of left ventricular performance in hypertensive patients by speckle tracking echocardiography: Correlation with brain natriuretic peptide

The Egyptian Heart Journal, 2014
Background: Hypertension results in hemodynamic changes ranging from maladaptive left ventricular hypertrophy (LVH) to heart failure. Two-dimensional speckle tracking echocardiography (2D-STE) allows rapid and accurate analysis of regional and global ...

Properties of the strain rate sensitivity function produced by the linear viscoelasticity theory and existence of its maximum with respect to strain and strain rate

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2020
Strain rate sensitivity of stress-strain curves family generated by the Boltzmann–Volterra linear viscoelasticity constitutive equation (with an arbitrary relaxation modulus) under uni-axial loadings at constant strain rates is studied analytically as ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Strain hardening behaviors and strain rate sensitivity of gradient-grained Fe under compression over a wide range of strain rates

, 2016
In the present work, gradient-grained Fe was synthesized by means of surface mechanical grinding treatment, and then the compression behaviors of the coarse-grained Fe and the gradient-grained Fe were investigated under both quasi-static and dynamic ...
