Dissipative heat engine is thermodynamically inconsistent
, 2009 A heat engine operating on the basis of the Carnot cycle is considered, where the mechanical work performed is dissipated within the engine at the temperature of the warmer isotherm and the resulting heat is added to the engine together with an external ...

Approaching an Efficient and Feasible Carnot Engine by Carnot Cycle Analysis
Journal of Energy Research and Reviews, 2021 Based on the knowledge exhibited in the literature on the Carnot cycle, a preliminary study is carried out on Carnot machines capable of implementing the Carnot cycle at high thermal efficiency. Therefore, two engine structures are proposed: (i) reciprocating single and double-acting cylinder-based thermal engines implemented under a closed processes ...

Comment on: "Sadi Carnot on Carnot's theorem"
, 2003 Carnot established in 1824 that the efficiency $\eta_{C}$ of reversible engines operating between a hot bath at absolute temperature $T_{hot}$ and a cold bath at temperature $T_{cold}$ is equal to $1-T_{cold}/T_{hot}$.

Neurogastroenterology &Motility, EarlyView.The SLR maneuver is a valuable component of GERD evaluation. By establishing optimal thresholds for both effective EGJ challenge and accurate GERD prediction, we provide another step for standardized implementation in clinical practice. ABSTRACT Background Gastroesophageal reflux disease (GERD) arises from dysfunction of the anti‐reflux barrier.
