Left Main Stem Perforation: Management Strategies in a Potentially Catastrophic Event

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Left main stem coronary perforation is a potentially fatal complication of percutaneous coronary intervention if not recognized early and treated emergently. Treating left main stem perforation can be challenging due to the significant hemodynamic effect of one of the important steps, namely balloon tamponade.

Cooling system for high speed aircraft [PDF]

open access: yes, 1981
The system eliminates the necessity of shielding an aircraft airframe constructed of material such as aluminum. Cooling is accomplished by passing a coolant through the aircraft airframe, the coolant acting as a carrier to remove heat from the airframe ...

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes

open access: yesChemie Ingenieur Technik, EarlyView.
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,
