NEW CRETACEOUS ANTLION-LIKE LACEWINGS PROMOTE A PHYLOGENETIC REAPPRAISAL OF THE EXTINCT MYRMELEONTOID FAMILY BABINSKAIIDAE

New Cretaceous antlion-like lacewings promote a phylogenetic reappraisal of the extinct myrmeleontoid family Babinskaiidae

Abstract Babinskaiidae is an extinct family of the lacewing superfamily Myrmeleontoidea, currently only recorded from the Cretaceous.The phylogenetic position of this family is elusive, with inconsistent inferences in previous studies.Here we report on three new genera and species of Babinskaiidae from 24" Wall Oven the mid-Cretaceous Kachin amber

Ethanolic Media Effect on the Susceptibility to Stress Corrosion Cracking in an X-70 Microalloyed Steel with Different Aging Treatments

The objective of this research was to evaluate the stress corrosion cracking (SCC) of X-70 micro-alloyed steel in contact with bio-ethanol and E-50 gasohol.Environmental factors, including water (1%, 3% and 5%) and NaCl (10 mg/L and 32 mg/L), as well as two aging treatments were studied.Experimental values were obtained by the Slow Strain Rate Test
