The flow of a Casson fluid under periodic pressure gradient in a rigid tube, in the low-frequency limit has been examined. Results show that the quasi-steady solution, where time acts as a parameter and not as an independent variable, can be used to construct accurate solutions of such a flow, which are applicable to the flow of blood in small vessels of low shear rate. As an illustration, the flow under a sinusoidal positive pressure gradient was computed for the quasi-steady theory, and the nonlinear relation between flow and instantaneous pressure gradient was clearly shown by the blunting of the flow-rate curve, which occurs when the numerical magnitude of the pressure gradient is small.

A presentation of the most elementary form of pulsatile flow as an important prerequisite for the study of other flow applications in biological systems. The book provides in a single source a complete treatment of the fluid dynamics of flow with the required mathematics and emphasis on the basis mechanics. The style and level of this book make it accessible to students and researchers in biophysics, biology, medicine, bioengineering and applied mathematics working in theoretical and clinical work on the cardiovascular system, as well as in the design of new instrumentation, medical imaging systems, and artificial organs. With problems and exercises.

This book focuses mainly on the recent developments of all types of theoretical, mathematical, and computational conceptions, as well as modelling and simulation of specific research themes covering all scientific and technical disciplines from chemistry, physics, and engineering to biology and medicine. The book contains timely reviews and research covering fundamental and applied research aspects in all disciplines of natural sciences, including their historical representations and philosophical perspectives. The book discusses the fact that the largest and smallest values of the fukui function and local softness do not necessarily correspond to the softness and hardness regions of the molecules such as porphyrins. The authors have adopted two popular calculation procedures for this venture. One is the very old Hückel molecular orbital calculation, and the other is one of best semi-empirical AM-1 procedures for such systems. Our finding is that neither the fukui functions nor the local softnesses can predict the preferred donor sites of porphyrins toward metal ions.
