Experimental investigation on the synchronization characteristics of a pitch-plunge aeroelastic system exhibiting stall flutter.

This study focuses on characterizing the bifurcation scenario and the underlying synchrony behavior in a nonlinear aeroelastic system under deterministic as well as stochastic inflow conditions. Wind tunnel experiments are carried out for a canonical pitch-plunge aeroelastic system subjected to dynamic stall conditions. The system is observed to undergo a subcritical Hopf bifurcation, giving way to large-amplitude limit cycle oscillations (LCOs) in the stall flutter regime under the deterministic flow conditions.

Disseminated intravascular coagulation in a case of fatal lindane poisoning.

After an accidental or intentional ingestion of lindane, clinical manifestations of poisoning may include rapid onset of nausea and vomiting, coma, seizures, respiratory failure, and death. While rhabdomyolysis, secondary renal failure, and aplastic anemia have also been reported, coagulopathies have not been observed following poisoning with this pesticide. In this case report we describe a 43-year-old female who intentionally ingested 8 oz of a 20% lindane solution.
