Study of Soot Deposits during Continuous Methane Pyrolysis in a Corundum Tube

open access: yesApplied Sciences, 2023
Methane pyrolysis is one of the promising methods for producing low-carbon hydrogen, while one of the main problems of methane pyrolysis technology is soot clogging of the reactor space.

The Influence of Biofuels Addition on Shock-Induced Ignition and Combustion of Methane–Hydrogen Mixtures

open access: yesFire, 2023
The ignition and combustion of three-component methane–hydrogen biofuel mixtures, considered as prospective fuels, were experimentally and numerically studied. Ignition delays in argon-diluted methane–hydrogen mixtures partially substituted with methanol

Quantum Decoherence at Finite Temperatures [PDF]

open access: yes, 2015
We study measures of decoherence and thermalization of a quantum system $S$ in the presence of a quantum environment (bath) $E$. The whole system is prepared in a canonical thermal state at a finite temperature.

Monitoring temperature [PDF]

open access: yesBritish Journal of Nursing, 2019
This article explains the importance of temperature monitoring observations and highlights that the procedure is a fundamental aspect of nursing care. It discusses the physiology of temperature regulation, introduces different types of temperature monitoring devices and provides a step-by-step guide on how to take a temperature using a tympanic ...

Two-dimensional Brownian motion of active particle on superfluid helium surface

open access: yesScientific Reports, 2023
We report an experimental study of the 2D dynamics of active particles driven by quantum vortices on the free surface of superfluid helium at T = 1.45 К. The particle motion at short times (

Sensing temperature [PDF]

open access: yesCurrent Biology, 2013
Temperature is an omnipresent physical variable reflecting the rotational, vibrational and translational motion of matter, what Richard Feynman called the "jiggling" of atoms. Temperature varies across space and time, and this variation has dramatic effects on the physiology of living cells.

On the Possibility of Cross-Flow Vortex Cancellation by Plasma Actuators

open access: yesAerospace, 2023
Cancellation of the cross-flow vortices in a swept-wing boundary layer is attempted by plasma actuator array in numerical simulation. The response of the boundary layer to the stationary excitation by a single actuator section is measured experimentally ...
