Unstable behavior of hydrogen-air lean premixed flames (Effects of unburned-gas temperature, heat loss and scale)

open access: yesNihon Kikai Gakkai ronbunshu, 2020
Unstable behavior of hydrogen-air lean premixed flames was studied by numerical calculations of two-dimensional unsteady reactive flow to clarify the effects of unburned-gas temperature, heat loss and scale. We adopted the numerical model containing the

The relationship between parental behavior and the reproductive strategy of daughter is mediated by the development of machiavellianism personality

open access: yesHeliyon, 2023
Females who receive harsh, rejective, and inconsistent nurturing behavior from parents, are predicted to adopt mating strategies, such as short-term and unstable pair bonds with males. The speculation that, the rejective behavior a female receives during

Numerical simulation of the behavior of kinematically unstable slopes under dynamic influences

open access: yesAdvanced Engineering Research, 2022
Introduction. The concept of estimating the dynamic parameters of the “base — weakened layer — block” system is proposed, taking into account the physical nonlinearity of the material and the kinematic method of excitation of vibrations.
