The Enskog–Vlasov equation provides a consistent description of the microscopic molecular interactions for real fluids based on kinetic and mean-field theories. fluid flows in nano-channels are investigated by Bhatnagar–Gross–Krook (BGK) type model, which simplifies complicated collision operator enables large-scale engineering design simulations. density distributions found to exhibit inhomoge...

BACKGROUND Pulpal reaction to restorative materials depends on marginal microleakage, which is a dynamic phenomenon that allows bacteria and fluids to traverse across the tooth-restoration interface. Glass-ionomer cement (GIC) exhibits low microleakage due to direct bonding to tooth structures. Hydroxyapatite (HAP) based on the similarity with tooth structure may decrease the microleakage. The ...

A new dual-fluid concept was studied that could eventually find application for cold-gas propulsion for small space satellites or other constant flow applications. In basic form, the concept uses two different refrigerant working fluids, each having a different saturation vapor pressure. The higher vapor pressure refrigerant remains in the saturation phase and is used to pressurize the lower sa...

Highly sensitive analytical techniques have allowed a massive increase in the amount of pharmacokinetic data which is useful to estimate the toxicity of the particular drugs. Generally available analytical techniques may not provide sufficient information to identify the all these toxic substances present in biological fluids at low concentrations. So, modifications to generally available analy...
