In view of problems that existing coal mine electric locomotive safety control cannot effectively prevent red light running, rear-end collision and collision, a kind of King Sleigh Storage Bed safety protection system of mine electric locomotive was designed.The system adopts radio frequency wireless communication technology and uses signals of sig
The spread of the COVID-19 pandemic and the need for online teaching methods in accounting education have Shoe Care Kits led to changes in training in this field.Despite its many challenges, online education has provided an opportunity to revolutionise the quality, effectiveness, and efficacy of education.Before the COVID-19 pandemic, many research
The heat and mass transfer characteristics of natural convection about a vertical surface embedded in a saturated porous Cards medium subject to variable viscosity are numerically analyzed, by taking into account the diffusion-thermo (Dufour) and thermal-diffusion (Soret) effects.The governing equations of continuity, momentum, energy, and concentr
Abstract Background Detailed modelling of the neutral mutational process in cancer cells is crucial for identifying driver mutations and understanding the mutational mechanisms that act during cancer development.The neutral mutational process is very complex: whole-genome analyses have revealed that the mutation rate differs between cancer types, b
