Book Description
Trade magazines and review articles describe MWD in casualterms, e.g., positive versus negative pulsers, continuous wavesystems, drilling channel noise and attenuation, in very simpleterms absent of technical rigor. However, few trulyscientific discussions are available on existing methods, let alonethe advances necessary for high-data-rate telemetry. Withouta strong foundation building on solid acoustic principles, rigorousmathematics, and of course, fast, inexpensive and efficient testingof mechanical designs, low data rates will impose unacceptablequality issues to real-time formation evaluation for years tocome. This book promises to change all of this. The lead authorand M.I.T. educated scientist, Wilson Chin, and Yinao Su,Academician, Chinese Academy of Engineering, and other teammembers, have written the only book available that developsmud pulse telemetry from first principles, adapting sound acousticprinciples to rigorous signal processing and efficient wind tunneltesting. In fact, the methods and telemetry principlesdeveloped in the book were recently adopted by one of theworld’s largest industrial corporations in its mission toredefine the face of MWD. The entire engineering history for continuous wave telemetry iscovered: anecdotal stories and their fallacies, original hardwareproblems and their solutions, different noise mechanisms and theirsignal processing solutions, apparent paradoxes encountered infield tests and simple explanations to complicated questions, andso on, are discussed in complete “tell all” detail forstudents, research professors and professional engineersalike. These include signal processing algorithms, signalenhancement methods, and highly efficient “short” and“long wind tunnel” test methods, whose results can bedynamically re-scaled to real muds flowing at any speed. Amust read for all petroleum engineering professionals!

Book Description
With unflinching candor, a moving graphic novel follows a young woman’s return from war and her bond with two dogs—one who saves her life in Iraq, and another who helps her reclaim it at home. Liz served in Iraq with her trusty military working dog, Ender, by her side. But now that her tour is over, she has to readjust to life in her small New Hampshire town. Despite being surrounded by people she’s known her whole life, Liz feels entirely alone and soon gets trapped in a downward spiral of flashbacks and blackout drinking. Things seem destined for a bad end, but when Liz’s on-again-off-again boyfriend, Ben, almost hits a stray dog while she is in the car, things start to change. Brutus might just be the only thing that can bring her back from the brink. Brian David Johnson, Jan Egleson, Laila Milevski, and Karl Stevens have created a searing and honest portrait of reentry to civilian life after war and a touching exploration of the bond between dog and human.

Book Description
Nuclear fuel is occasionally warranted to produce a stipulated average Mwd/ton for discharged fuel. Mwd/ton is defined as the megawatt days of heat produced per 2000 pounds of total fissionable and fertile isotopes initially present. In the history of nuclear power reactors, Mwd/ton has been a difficult number to measure accurately. Measurements performed in different laboratories are not always in agreement. A fuel burnup group is preparing tentative procedures which will help standardize the field of burnup analysis. The purpose of this report is to evaluate some of the existing methods for burnup analysis and to select, if possible, the one best suited for warranty purposes.
