The development of scientific concepts is usually described as a pathway from the realm of concrete life to the abstract principles of science, in a higher level of generalisation.In this paper, we argue that the appropriation of scientific concepts occurs in the return to concrete in a higher level of conceptual development, which means a transiti
Assessment of the exergy, emissions, and combustion characteristics of a diesel engine operating on low-glyceride biodiesel blended with diesel fuel
The behavior of biofuels depends on glyceride content, water content, viscosity, density, and other properties that produce different effects on emissions and fuel performance.Therefore, this work performs an experimental evaluation of the performance of low glyceride palm oil biodiesel blended with diesel fuel operating in a compression ignition e
Improving Mechanical Oscillator Cooling in a Double-Coupled Cavity Optomechanical System with an Optical Parametric Amplifier
We investigate the cooling phenomenon of a mechanical oscillator in a double-coupled cavity optomechanical system.Our model includes two single-mode optical cavities.The left cavity is an optomechanical system with an optical parametric amplifier, and the right cavity is a standard optical cavity.The two optical cavities couple with each other by e
