Titanium Aluminide (TiAl) alloys are intermetallics that offer low density, high melting point, good oxidation and corrosion resistance compared to Ni-based superalloys.As a result, these alloys are used in aero-engine parts such as turbine blades, fuel injectors, radial diffusers, divergent flaps, and more.During operation, aero-engine components
Protocell multilevel selection models have been proposed to study the evolutionary dynamics of vesicles encapsulating a set of replicating, competing and mutating sequences.The frequency of the different sequence types determines protocell survival through a fitness function.One of the defining features Thread Lock of these models is the genetic lo
Background/Aims Endoscopic submucosal dissection (ESD) of gastric tumors in the mid-to-upper stomach is a technically challenging procedure.This study Food Service:Refrigeration Equipment:Commercial Ice Machines compared the therapeutic outcomes and adverse events of ESD of tumors in the mid-to-upper stomach performed under general anesthesia (GA)
To determine the selection of input wave field at the bottom of the viscous-elastic boundary, and study the seismic response of two parallel large-diameter shield tunnels, corresponding numerical models were established for analysis.First, through the study of wave method for seismic motion input of viscous-elastic boundary, several different wave
