Abstract Artificial lift is a vital part of the life many oil wells worldwide. Using several artificial methods can prolong and increase recovery significantly. One most applied nowadays electrical submersible pump (ESP). This method has ability to handle large volumes hydrocarbons applicable under conditions in both offshore onshore reservoirs. Even though ESP been extensively for years, it st...
In order for the rapidly emerging field of MicroElectroMechanical Systems (MEMS) to meet its extraordinary expectations regarding commercial impact, issues pertaining to how they fail must be understood. We identify failure modes common to a broad range of MEMS actuators, including adhesion (stiction) and friction-induced failures caused by improper operational methods, mechanical instabilities...
BACKGROUND Atrial standstill manifests as absence of any atrial electrical activity in the surface ECG leads. Persistent atrial standstill secondary to acute myocarditis is extremely rare. CASE REPORT 10-year-old girl had atrial standstill and heart failure due to acute myocarditis. After recovery from myocarditis, heart failure resolved, but the atrial standstill persisted.
