Motivation Fuel lean combustion is often employed to reduce pollutant emissions (CO, NOx,...) and increase gas turbine lifetime via reduced temperature. However, lean combustion is susceptible to thermoacoustic instabilities and lean blowout (LBO). Thermoacoustic instabilities are due to the coupling of heat release to acoustic oscillations, and lead to reduced combustion efficiency and increas...
Two cases of vein patch blowout were observed five and seven days after carotid bifurcation endarterectomy with patch angioplasty. Both patients died in spite of emergency reoperation. One patient developed respiratory failure with subsequent fatal cardiac arrest seven days after reoperation; the other died of extensive hemispheric infarction on the fifth postoperative day. At reoperation both ...
Strange nonchaotic attractors are attractors that are geometrically strange, but have nonpositive Lyapunov exponents. We show that for dynamical systems with an invariant subspace in which there is a quasiperiodic torus, the loss of the transverse stability of the torus can lead to the birth of a strange nonchaotic attractor. A physical phenomenon accompanying this route to strange nonchaotic a...
Situation-aware disaster management (SADIM) is a continuous decision-making and action taking process. This process requires prior knowledge of the ongoing environment context. SADIM comprises two major processes: situation awareness (SA) - cognitive that assesses current situations anticipate future in environment; and, (DM) which preventing, preparing, responding, recovering for from disaster...
We describe a patient who sustained a blowout fracture of the superior orbital roof without an orbital rim fracture. The initial CT study (obtained with 10-mm-thick sections) did not show herniation of the intraorbital fat into the anterior cranial fossa; however, thin (3-mm-thick) direct orbital sections showed a fracture of the midportion of the superomedial orbital roof with displacement of ...
Kessler et al. (Reports, 21 January 2011, p. 312) reported that methane released from the 2010 Deepwater Horizon blowout, approximately 40% of the total hydrocarbon discharge, was consumed quantitatively by methanotrophic bacteria in Gulf of Mexico deep waters over a 4-month period. We find the evidence explicitly linking observed oxygen anomalies to methane consumption ambiguous and extension ...
Myocardial rupture is a rare imaging diagnosis given its clinical severity and high mortality. Early findings should be promptly communicated to the trauma service to ensure immediate intervention. We present a rare case of blowout perforation of the right ventricle which was prospectively diagnosed on computed tomography (CT) leading to emergent operative repair. The patient subsequently survi...
This report is of a patient with acute carotid blowout syndrome that was managed successfully with emergency placement of a covered stent. A 68-year-old man with carcinoma of the tongue had been treated surgically and underwent repeated radiotherapy for recurrence. He presented with intermittent brisk bleeding from a wound in his neck. An urgent carotid angiogram was performed and revealed a ps...
