Characteristics of biogas-oxygen micro counterflow diffusion flames

open access: yesNihon Kikai Gakkai ronbunshu, 2015
The characteristics of biogas-oxygen diffusion flames were experimentally investigated using small counterflow burners, where the apparent equivalence ratio was set to unity.

Stretching rates and equivalent length near the tropopause [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2003
Diagnostics of mixing in the upper troposphere/lower stratosphere region reveal interesting seasonal and interannual variability and illustrate how the subtropical tropopause can be identified with a region of minimum mixing, a partial barrier to the transport of air between the troposphere and stratosphere.

Predicted time evolutions of SF stretch and turnover rate in response to different frequencies of uniaxial stretch. [PDF]

open access: yes, 2013
The maximum and minimum values of the population-averaged fiber stretch during a cycle (A) and the rate of SF turnover (B) are shown for simulations of 10% cyclic uniaxial stretch at frequencies of 1 (red), 0.1 (blue) and 0.01 Hz (black) using the ...

Sinoatrial Node Structure, Mechanics, Electrophysiology and the Chronotropic Response to Stretch in Rabbit and Mouse

open access: yesFrontiers in Physiology, 2020
The rhythmic electrical activity of the heart’s natural pacemaker, the sinoatrial node (SAN), determines cardiac beating rate (BR). SAN electrical activity is tightly controlled by multiple factors, including tissue stretch, which may contribute to ...

Predicted time evolutions of circular variance, SF stretch and fiber turnover rate in response to different frequencies of equibiaxial stretch. [PDF]

open access: yes, 2013
The circular variance (A), the maximum and minimum values of the population-averaged fiber stretch during a cycle (B), and the rate of stress fiber turnover (C) are shown for simulations of 10% cyclic equibiaxial stretch at frequencies of 1 (red), 0.1 ...

Cyclic stretch increases splicing noise rate in cultured human fibroblasts

open access: yesBMC Research Notes, 2011
Background Mechanical forces are known to alter the expression of genes, but it has so far not been reported whether they may influence the fidelity of nucleus-based processes.

Stream self-purification efficiency / Reguliuoto upelio savaiminio apsivalymo efektyvumo vertinimas

open access: yesMokslas: Lietuvos Ateitis, 2015
The article identifies factors that have influence on the processes of river self-purification from biogenic substances when the stretches of the river are regulated and unregulated.

Stretch Rate and Displacement Speed Correlations for Increasingly-Turbulent Premixed Flames [PDF]

open access: yes, 2018
Probability density functions of the components of stretch rate are investigated using a previously-published Direct Numerical Simulation dataset spanning a range of turbulence intensities in the Thin Reaction Zones (TRZ) regime.

Physical Biology of Axonal Damage

open access: yesFrontiers in Cellular Neuroscience, 2018
Excessive physical impacts to the head have direct implications on the structural integrity at the axonal level. Increasing evidence suggests that tau, an intrinsically disordered protein that stabilizes axonal microtubules, plays a critical role in the ...

Ranolazine-Mediated Attenuation of Mechanoelectric Feedback in Atrial Myocyte Monolayers

open access: yesFrontiers in Physiology, 2020
BackgroundMechanical stretch increases Na+ inflow into myocytes, related to mechanisms including stretch-activated channels or Na+/H+ exchanger activation, involving Ca2+ increase that leads to changes in electrophysiological properties favoring ...
