TJ Overcame His Fear of cats in TJ and the Cats and his fear of ghosts in TJ and the Haunted House. Now he's not so keen on facing his fear of failure. His best friend Seymour is determined to come up with the latest greatest invention, and TJ's gran expects TJ to build a rocket. The kittens, T-Rex and Alaska, are eager to get involved. When the first rocket that TJ builds plummets out of the sky, no parachute in sight, TJ is sure that his efforts are doomed. But are they?

The purpose of this book is to discuss, at the graduate level, the methods of performance prediction for chemical rocket propulsion. A pedagogical presentation of such methods has been unavailable thus far and this text, based upon lectures, fills this gap. The first part contains the energy-minimization to calculate the propellant-combustion composition and the subsequent computation of rocket performance. While incremental analysis is for high performance solid motors, equilibrium-pressure analysis is for low performance ones. Both are detailed in the book's second part for the prediction of ignition and tail-off transients, and equilibrium operation. Computer codes, adopting the incremental analysis along with erosive burning effect, are included. The material is encouraged to be used and presented at lectures. Senior undergraduate and graduate students in universities, as well as practicing engineers and scientists in rocket industries, form the readership.

This three-volume reference work provides an up-to-date presentation and analysis of the U.S. wars of the 21st century, addressing their backgrounds, causes, courses, and consequences. It serves as an indispensable resource for students seeking to understand the role of the United States in the world today. Addressing the U.S. conflicts in Iraq, Afghanistan, and the Global War on Terror from the year 2001 to the present, this comprehensive, three-volume encyclopedia covers the significant individuals, key events, and important places involved in these recent military events. Beginning with the rise of Al Qaeda in the 1990s and the attacks on September 11, 2001, and covering events through ISIS's dramatic surge in Iraq and Syria, the hundreds of detailed entries also examine historical trends; nations and ethnicities involved in the conflicts; influential figures and organizations; economic, political, diplomatic, and cultural influences; wars, campaigns, and battles; and important weapons systems. The set's A–Z organization makes it an easy-to-use ready reference for high school and college students. Perspective essays on several controversial topics—such as the use of torture and the effects of the Patriot Act—serve to inspire readers to apply critical thinking. A detailed chronology is provided to help students place all the important events that have occurred in the Afghanistan War, Iraq War, and War on Terror. Each of the chronologically arranged primary documents is introduced with a brief overview to provide important background information and context.

The Retirement Series documents Jefferson's written legacy between his return to private life on 4 March 1809 and his death on 4 July 1826. During this period Jefferson founded the University of Virginia and sold his extraordinary library to the nation, but his greatest legacy from these years is the astonishing depth and breadth of his correspondence with statesmen, inventors, scientists, philosophers, and ordinary citizens on topics spanning virtually every field of human endeavor.--From publisher description.
