Dynamic strength differential and Bauschinger effects in an extruded AZ80 magnesium alloy

Journal of Materials Research and Technology
Quasi-static and high-rate tension and compression properties of an extruded AZ80 Mg alloy rod were investigated at loading rates of 0.001 and 500 s−1.

Research on Mechanical Response of Pavement Structure to Differential Settlement of Subgrade on Highway Widening

Advances in Materials Science and Engineering, 2021
Based on the widening project of Ri-Lan highway in China, the finite element model is established by PLAXIS. By applying differential settlement at the bottom of the pavement, the mechanical response of the pavement structure is analysed.

Education and grip strength among older Thai adults: A mediation analysis on health-related behaviours

SSM: Population Health, 2021
Background: Previous studies have investigated the effect of differential educational attainment at younger ages on health disparities among older adults, but how such an effect can be attenuated remains understudied.

Effects of strength training on osteogenic differentiation and bone strength in aging female Wistar rats [PDF]

Scientific Reports, 2017
AbstractThe effects of strength training (ST) on the mechanical bone strength and osteogenic differentiation of bone marrow mesenchymal stromal cells (BMSCs) from adult, aged and exercised aged rats were determined. The exercised aged animals displayed higher values of areal bone mineral density, compression test, alkaline phosphatase activity (ALP ...

Burzyński yield condition vis-à-vis the related studies reported in the literature

Engineering Transactions, 2014
The paper is written in accompaniment of the publication of English translation of W. Burzyński’s paper, which deals with the yield criterion for materials revealing the sensitivity of yield strength to pressure derived by W. Burzyński during preparation

Destabilization of α-helical structure in solution improves bactericidal activity of antimicrobial peptides: Opposing effects on bacterial and viral targets [PDF]

, 2016
We have previously examined the mechanism of antimicrobial peptides on the outer membrane of vaccinia virus. Here we show that the formulation of peptides LL37 and magainin-2B amide in polysorbate 20 (Tween-20™) results in greater reductions in virus ...
