Myocardial revascularization without extracorporeal circulation; Why hasn't it convinced yet?
Annals of Cardiac Anaesthesia, 2017 Extracorporeal circulation has led to a great development in cardiovascular surgery during the last five decades. Its time-proven efficacy and safety have made on-pump coronary artery bypass grafting (CABG) the gold standard method of surgical ...

Energy-efficient control of pump units based on neural-network parameter observer [PDF]
, 2020 An observer based on an artificial neural network was designed. The observer determines the pumping unit performance depending on the operating point. Determination is based on the measured technological coordinates of the system and the pressure of the ...

Coronary artery bypass surgery in high-risk patients
Current Controlled Trials in Cardiovascular Medicine, 2005 Background In high-risk coronary artery bypass patients; off-pump versus on-pump surgical strategies still remain a matter of debate, regarding which method results in a lower incidence of perioperative mortality and morbidity. We describe our experience

On pumping astronomical masers
The Astrophysical Journal, 1986 We have examined the possibility that astronomical masers are pumped collisionally in regions where the charged particle temperature is larger than that of the neutral particles. Such conditions occur naturally in the magnetic precursors of MHD shocks.

Effect of Shear on Pumped Capillary Foams
Industrial & Engineering Chemistry Research, 2023 Foam flow in many applications, like firefighting and oil recovery, requires stable foams that can withstand the stress and aging that result from both shear and thermodynamic instability. Events of drainage and coarsening drive the collapse of foams and greatly affect foam efficacy in processes relying on foam transport.

Surgical correction of ruptured aneurysms of the sinus of Valsalva using on-pump beating-heart technique [PDF]
, 2010 Background Rupture of aneurysms of the sinus of Valsalva results in abrupt onset of congestive heart failure. On-pump beating-heart surgery may reduce cardiac impairment by maintaining coronary blood flow and avoiding cardioplegia.
