Book Description
Oil spills at sea are a severe environmental concern. They can occur during the various stages of well-drilling, repair operations or transportation. The spreading of oil occurs due to the pollutant's tendency to flow over itself. Knowledge of its physical properties during the phenomenon, such as velocities and spatial positions, allows the timely adoption of environmental protection measures. This book presents, in a simple and objective way, the development and implementation of purely Lagrangian numerical modelling using the Smoothed Particle Hydrodynamics (SPH) method for the study of the spreading of oil in its first stage (gravity-inertial regime) on a calm sea. The computational code's implementation and validation were carried out through the simulation of classical problems in the scientific literature, i.e., heat diffusion in a homogeneous flat plate, a still volume of water inside an immobile reservoir and a dam failure. From the coupling of the software with a collision detection and response algorithm, numerical results in concordance with the curve adjusted by James Fay (a pioneering scientist in the study of oil spills) for the prediction of oil slick diameters at the end of the gravity-inertial regime were achieved.

Book Description
This book is based on results obtained over a decade of study and research. It questions the use of dynamic molecular models in the continuum scale providing alternative solutions to open problems in the literature. It provides a physical-mathematical understanding of the differential equations that govern fluid flow and energy transport, serving as a reference to the application of Smoothed Particle Hydrodynamics in continuum fluid mechanics and transport phenomena. The physical-mathematical modelling of the problems in the continuum scale and the employment of the SPH method for solving the equations are presented. Examples of applications in continuum fluid mechanics with numerical results and discussions are also provided. This literature defends the concepts of continuum mechanics and the application of boundary treatment techniques that do not violate the laws of physics.

Book Description
The flow of gravity currents and intrusions is a subject of active research and engineering application. Currently, there are no formal teaching courses for this topic. Materials and information available in the market are scattered and dated. Researchers and engineers face difficulties in acquiring the 'state-of-the-art' knowledge. The book bridges this gap between the need and supply of the relevant insight and know-how.Written by a renowned author who is a recognized authority in the field, this unique compendium assembles the relevant knowledge into a systematic and unified framework. The presentation is gradual from the elementary to the frontier, and accessible to readers with only a basic background in fluid mechanics and applied mathematics. This will facilitate the systematic acquirement and application of available knowledge to both practical problems and further research.This must-have volume is a useful monograph — that can also serve as a textbook in advanced courses — for researchers, students, engineers and applied mathematicians in the fields of civil engineering, hydraulic engineering, mechanical engineering, ocean engineering and environmental engineering.

Book Description
This is the first-ever book on smoothed particle hydrodynamics (SPH) and its variations, covering the theoretical background, numerical techniques, code implementation issues, and many novel and interesting applications. It contains many appealing and practical examples, including free surface flows, high explosive detonation and explosion, underwater explosion and water mitigation of explosive shocks, high velocity impact and penetration, and multiple scale simulations coupled with the molecular dynamics method. An SPH source code is provided and coupling of SPH and molecular dynamics is discussed for multiscale simulation, making this a friendly book for readers and SPH users.

Book Description
Hamlet Studies (1979-2003), an international journal devoted exclusively to one work of art, Hamlet, presented a vast wealth of research on Shakespeare’s play, contributions from well-established critics from across the globe. This book focuses on the critical contribution Hamlet Studies made to the play’s scholarship, bringing together textual criticism, twentieth century critical thought and performance-based contributions. It represents a valuable and comprehensive guide for students and teachers studying Shakespeare in colleges and universities the world over.

Book Description
Since the 1979 Revolution in Iran and the end of a close relationship between the US and the Shah, successive American administrations – including the Obama Administration – have tried to contain Iran by various means, particularly sanctions and military threats. Even though President Obama came to office promising to engage Iran, in reality his administration has followed the policy of “tough diplomacy,” which has included, among other acts, imposing draconian sanctions against Iran. Following the author’s earlier book on the history of containment of Iran and Iraq, the current book examines closely the Obama Administration’s policy toward Iran, as well as the role played by Israel, the European Union and the International Atomic Energy Agency (IAEA) in the implementation of this policy. Specifically, it is argued that the policy of “tough diplomacy,” designed mostly by those associated with the Israeli lobby groups, was intended to give an ultimatum to Iran in some direct meetings, telling Iran to either accept the US-Israeli demands or face aggression. The meetings were also intended to create the illusion of engaging Iran in order to gain international support for aggressive actions. Barack Obama announced this policy in his speeches as a Senator, particularly at the American Israel Public Affairs Committee policy conferences. After he became president in 2008, the policy of “aggressive diplomacy” was put in motion. While pretending to engage Iran in diplomacy, the Obama Administration, in coordination with the US Congress and the government of Israel, pushed for the most confrontational IAEA reports on Iran and an unprecedented set of unilateral and multilateral sanctions. The US and Israel also engaged in a campaign of military threats, sabotage and assassination of Iranian nuclear scientists. Yet, after four years of hostilities, the policy of “tough diplomacy” failed to achieve many of its goals and failed to contain Iran.

Book Description
Negationism is an irrational but useful tool for manipulation. Almost nobody supports the Flat Earth model or the geocentrism, but some European educational laws still offer a confessional education that treats as real the myth about Adam and Eve. This book recounts the struggle that human mind has maintained, over two millennia, against creationist myths. The journey takes place between cosmogonies, theological dogmas, natural philosophy, Deism and the inevitable secularism of the Age of Enlightenment.

Book Description
Fluid Mechanics, Second Edition deals with fluid mechanics, that is, the theory of the motion of liquids and gases. Topics covered range from ideal fluids and viscous fluids to turbulence, boundary layers, thermal conduction, and diffusion. Surface phenomena, sound, and shock waves are also discussed, along with gas flow, combustion, superfluids, and relativistic fluid dynamics. This book is comprised of 16 chapters and begins with an overview of the fundamental equations of fluid dynamics, including Euler's equation and Bernoulli's equation. The reader is then introduced to the equations of motion of a viscous fluid; energy dissipation in an incompressible fluid; damping of gravity waves; and the mechanism whereby turbulence occurs. The following chapters explore the laminar boundary layer; thermal conduction in fluids; dynamics of diffusion of a mixture of fluids; and the phenomena that occur near the surface separating two continuous media. The energy and momentum of sound waves; the direction of variation of quantities in a shock wave; one- and two-dimensional gas flow; and the intersection of surfaces of discontinuity are also also considered. This monograph will be of interest to theoretical physicists.
