ASYMPTOTIC ANALYSIS OF HYDRAULIC FRACTURE CRACK PROCESS GROWTH

In this work the self-similar solution of a problem of propagation of Nutritionals - Thickeners hydraulic fracture crack is presented.It is proposed that a crack is focused vertically and research of of its development process is analyzed within the coupled problem of the hydrodynamics theory (flow of viscous fluids) and the linear theory of elasti

Abstract Although much is known about the reproductive biology of pond-breeding frogs, there is comparatively little information about terrestrial-breeding anurans, a highly successful and diverse group.This study investigates the activation and in vitro fertilization of eggs of AC-AC Transformers the Puerto Rican coqui frog obtained by hormonally
