The in-service properties and performance of dual-phase Zr Ti alloys depend on their crystallographic texture, which develops during hot-working is affected by interactions between the ? ? phases deformation, annealing phase transformation. Recent work hot-rolled Zr-2.5Nb has shown that texture two are related, with coupled strengthening near {112¯0}?101¯0?, produces strong 0002 pole intensitie...

The Lithiotis facies represents an Early Jurassic global bioevent characterized by a remarkable spread of gregarious bivalves, which produced large sedimentary bodies in tropical shallow-water marine environments. most peculiar and common genera Lithiotis, Cochlearites Lithioperna, with aberrant extremely elongated or strongly flattened shells, have been studied since the second half nineteenth...

Expressions for describing Gaussian beams focused by a lens with spherical aberration have been derived. Numerical results show that, when the coefficient of the spherical aberration is negative, one can obtain flattened laser irradiance at two positions along the focused field. The larger the coefficient of negative spherical aberration, the larger the flatness is. The effect of the Fresnel nu...

For decades, management consultants and the popular business press have urged large firms to flatten their hierarchies. Flattening (or delayering, as it is also known) typically refers to the elimination of layers in a firm’s organizational hierarchy, and the broadening of managers’ spans of control. The alleged benefits of flattening flow primarily from pushing decisions downward to enhance cu...
