In this study we suggest that the velocity of water entering the cervical esophagus can be used as an index of pharyngeal swallowing function. In this article, the basic in vitro principles of water and viscous water flow velocity evaluation using ultrasonic methods are introduced. Water flow involving small gas bubbles passing through a silicon tube could be monitored in the B-mode images and ...

In this research, Quantum-mechanical calculations were performed at the HF method with the 6-31+G*basis set and at the B3LYP method with the 6-31+G* basis set in the gas phase and five solvents such as water, DMSO, methanol, ethanol and dichloromethane at six temperatures. According to these theoretical results of IR, we extracted thermo chemical parameters such as enthalpy (∆H Kcal/mol), Gibbs...

A dynamically operated sorption-enhanced water–gas shift reactor is modelled to leverage its performance by means of model-based process design. This shall provide CO2-free synthesis gas for e-fuel production from pure CO. The nonlinear model equations describing simultaneous adsorption and reaction are solved with three numerical approaches in MATLAB: a built-in solver partial differential equ...
