Abstract Precise measurement and prediction of flame speed laminar burning velocity are essential for premixed combustion properties characterization, turbulent models validation, progress, validation chemical kinetic models. Besides, the problem lack fossil fuel, planet pollution, production several fuel alternatives led researchers to reexamine process optimize consumption. So, it would be ne...

In this work, an experimental study and kinetic characterization of the combustion process a morphologic hydrogen/methane–air mixtures are presented. The was performed in optical access cylindrical constant-volume bomb. This bomb is equipped to register instantaneous pressure during records images using high-speed Schlieren technique. provides straightforward information compute flame propagati...

Two distinct rotational isomers of thioanisole-d1 (C6H5S-CH2D) and thioanisole-d2 (C6H5S-CHD2) with respect to the internal rotation of the methyl moiety have been identified and characterized spectroscopically using the resonantly enhanced two photon ionization, UV-UV hole burning, and slow-electron velocity map imaging techniques. From the statistical weights, the definite assignment for the ...

A familiar analogy to the propagation of the electric wave in a nerve lies in the burning of a cigarette. This analogy, which has persisted through several editions of popular textbooks of physiology, has never been elaborated beyond a cursory mention. In this article, the analogy is reinvoked and refined to explain the cable properties of nerve, saltatory conduction, and some other factors aff...

–Plantar cutaneous stimulation has been shown to improve gait in Parkinson’s disease (PD), but the effects of different types of insoles have not been tested. We evaluated the immediate effect of different types of insoles on gait in PD patients and healthy older adults. Nineteen PD patients and nineteen healthy older adults performed and performed a walking task at their self-selected speed in...
