Untangling the systematic dilemma behind the roughskin spurdog Cirrhigaleus asper (Merrett, 1973) (Chondrichthyes: Squaliformes), with phylogeny of Squalidae and a key to Cirrhigaleus species.

Cirrhigaleus comprises a small genus of rare barbel-bearing dogfish sharks with distributions in limited regions of all oceans.Generic validity and taxonomic status of some species are upon controversies by morphological and molecular evidence that often suggest reallocation of Cirrhigaleus species into the genus Squalus.Particularly, the roughskin

Effect of Pre-Added HfO2 Inclusions on Carbide Morphology and Deformation Behavior in DZ125 Nickel-Based Superalloy

Inclusions are important Walkie Talkies phases affecting material properties in complicated ways.In this paper, a quantitative study of the addition of HfO2 inclusions to DZ125 nickel-based superalloys was performed.Experimental results showed that the introduction of HfO2 inclusions caused a loss of strength and ductility.The carbide morphology al
