Your Shabbos table is transformed into an uplifting experience when there is stimulating discussion of the weekly Torah reading. This enlightening volume contains stories, parables and insights on the weekly parashah that will delight every member of your household. Culled from Gemara, Midrash, commentaries and traditional lore, each selection is simply told, yet delivers an inspiring and profound message. A Shabbos Vort is a superb English translation of the work, Vekarasa L'Shabbos Oneg. A bestseller in the original Hebrew, this collection is a wonderful gift for your Shabbos host and a meaningful addition to your own home library. Compiled by Rabbi Yisroel Bronstein.
A method initially proposed by Bryson is extended to include asymmetric shedding. This method employs the impulsive flow analogy, and models each wake vortex using a single-point vortex. Free parameters inherent in the problem formulation are determined empirically. Normal force, pitching moment and yawing force coefficients are predicted for slender bodies with a nose fineness ratio greater than four and at a Mach number less than 0.9.

In the process of building and using models to comprehend the dynamics of the atmosphere, ocean and climate, the reader will learn how the different components of climate systems function, interact with each other, and vary over time. Topics include the stability of climate, Earths energy balance, parcel dynamics in the atmosphere, the mechanisms of heat transport in the climate system, and mechanisms of climate variability. Special attention is given to the effects of climate change.
This book brings together contributions by thirty scholars of journalism and history who look at what was reported about the Holocaust in the press of more than a dozen countries and languages. The studies examine the news media in America, England, and the Soviet Union, in Nazi Germany and Fascist Italy, in the Vatican, in occupied countries like Romania, Hungary, Greece, and Poland, and in Palestine under the British Mandate. By and large, the news media in the Allied countries neglected the story, while those in Nazi-dominated countries treated news related to the Holocaust in a wholly tendentious way. Thus the press, for a variety of reasons, did not cover the Holocaust, one of the central events of the twentieth century. As this book thoroughly demonstrates, it was perhaps the greatest ethical, professional, and political failure of the news media during World War II. If the press had been more responsible, and had informed the public in the West early enough and thoroughly enough, the history of the Holocaust might have been different and millions of victims might have survived.

The most teachable book on incompressible flow— now fully revised, updated, and expanded Incompressible Flow, Fourth Edition is the updated and revised edition of Ronald Panton's classic text. It continues a respected tradition of providing the most comprehensive coverage of the subject in an exceptionally clear, unified, and carefully paced introduction to advanced concepts in fluid mechanics. Beginning with basic principles, this Fourth Edition patiently develops the math and physics leading to major theories. Throughout, the book provides a unified presentation of physics, mathematics, and engineering applications, liberally supplemented with helpful exercises and example problems. Revised to reflect students' ready access to mathematical computer programs that have advanced features and are easy to use, Incompressible Flow, Fourth Edition includes: Several more exact solutions of the Navier-Stokes equations Classic-style Fortran programs for the Hiemenz flow, the Psi-Omega method for entrance flow, and the laminar boundary layer program, all revised into MATLAB A new discussion of the global vorticity boundary restriction A revised vorticity dynamics chapter with new examples, including the ring line vortex and the Fraenkel-Norbury vortex solutions A discussion of the different behaviors that occur in subsonic and supersonic steady flows Additional emphasis on composite asymptotic expansions Incompressible Flow, Fourth Edition is the ideal coursebook for classes in fluid dynamics offered in mechanical, aerospace, and chemical engineering programs.
This book provides an accessible introduction to the basic theory of fluid mechanics and computational fluid dynamics (CFD) from a modern perspective that unifies theory and numerical computation. Methods of scientific computing are introduced alongside with theoretical analysis and MATLAB® codes are presented and discussed for a broad range of topics: from interfacial shapes in hydrostatics, to vortex dynamics, to viscous flow, to turbulent flow, to panel methods for flow past airfoils. The third edition includes new topics, additional examples, solved and unsolved problems, and revised images. It adds more computational algorithms and MATLAB programs. It also incorporates discussion of the latest version of the fluid dynamics software library FDLIB, which is freely available online. FDLIB offers an extensive range of computer codes that demonstrate the implementation of elementary and advanced algorithms and provide an invaluable resource for research, teaching, classroom instruction, and self-study. This book is a must for students in all fields of engineering, computational physics, scientific computing, and applied mathematics. It can be used in both undergraduate and graduate courses in fluid mechanics, aerodynamics, and computational fluid dynamics. The audience includes not only advanced undergraduate and entry-level graduate students, but also a broad class of scientists and engineers with a general interest in scientific computing.
