This article presents an overview of the dynamics human heart and main goal is discussion its fluid mechanic features. We will see, however, that flow in can not be fully described without considering electrophysiology elastomechanics as well interaction with systemic pulmonary circulations which it strongly connected. Biologically, similar to all warm-blooded mammals satisfies same allometric ...

This paper provides an informal survey of the various mathematical structures that appear in the most basic models of fluid motion.

The minerals and energy industries worldwide are very upbeat about sustainable development. Many companies have sustainability managers. Unfortunately most of their effort in sustainable practice is directed towards the social and stakeholder interaction in the community. Very little effort is being made to apply sustainable practices to management of liquid waste tailings. Even though technolo...

In this study, the steady incompressible flow of a non-Newtonian sodium alginate (SA) fluid conveying copper nanoparticles (Cu) which flow within two vertical parallel plates is investigated by using the homotopy perturbation analytical scheme to solve the coupled nonlinear ordinary equations arising from the mechanics of the fluid. The developed analytical solutions are used to investigate the...

Polymer solutions and melts are viscoelastic; they exhibit fluidlike behavior in steady shear, but the initial response to an imposed deformation involves a material-dependent transient that may be many orders of magnitude longer than time scales associated with instrument inertia. Intrinsic material time scales can be identified with the dynamics of the macro­ molecular chains. Shaping process...

The pleural space separating the lung and chest wall of mammals contains a small amount of liquid that lubricates the pleural surfaces during breathing. Recent studies have pointed to a conceptual understanding of the pleural space that is different from the one advocated some 30 years ago in this journal. The fundamental concept is that pleural surface pressure, the result of the opposing reco...
