DOI: 10.1016/j.ijmecsci.2018.01.031
Abstract: Abstract In lubrication theory, the cross-film pressure variation is assumed negligible. It is questionable whether this is generally true. To validate this assumption, a finite-element software was used to solve the Navier-Stokes equations for plane… read more here.

DOI: 10.1021/acs.energyfuels.7b00895
Abstract: Thermal behavior of two principally different wax materials (viz., paraffin Russian grade P-2 and microcrystalline Sasol 0907) has been investigated using thermogravimetry and differential scanning calorimetry at atmospheric and elevated pressure. The variation of experimental… read more here.

DOI: 10.5114/ait.2020.100636
Abstract: BACKGORUND Current evidence suggests that intraoperative goal-directed haemodynamic therapy (GDT) should be considered for high-risk patients undergoing major gastrointestinal surgery. We aimed to evaluate if an algorithm using venoarterial carbon dioxide difference (CO2 gap) and… read more here.
