The great attention of scientific researches about vancomycin- resistant Enterococcus faecalis due to the great healthy problems in the world.Evaluation of E.faecalis virulence factors showed that all isolates (100%) were hemolysin, protease and aggregation substance producer, 30% were a gelatinase producer, and 40.7% were a lipase producer.The res
[Introduction] This paper mainly discusses the principles, methods and measures of lightning protection design of offshore floating photovoltaic power station to meet the safe operation of offshore floating photovoltaic power station in harsh climate conditions.[Method] Through the in-depth analysis of the marine environment, offshore floating phot
A six-component super-Ablowitz-Kaup-Newell-Segur (-AKNS) hierarchy is proposed by the zero curvature equation associated with Lie superalgebras.Supertrace identity is used to furnish the super-Hamiltonian structures for Grinders the resulting nonlinear superintegrable hierarchy.Furthermore, we derive the infinite conservation laws of the first two
Dynamic load due to gust for helicopter rotors directly affects the structural stress and flight performance.In case of gust, it may cause the loss of trust force or the increase of deflection for rotors.In current work, an effective coupled aeroelastic model based on a medium-deflection beam theory and a nonlinear unsteady aerodynamic model in the
The late rising pacing threshold is an alarming situation in which a possibility of lead dislodgement is usually considered first.This condition is usually picked up on routine follow-up interrogation; however, it can clinically manifest as syncope due to Dryer Heat Switch bradyarrhythmia.We report such a case in a 59-year-old male presenting to th
