Book Description
The purpose and subject of this book is to provide a comprehensive overview of all types of phantoms used in medical imaging, therapy, nuclear medicine and health physics. For ionizing radiation, dosimetry with respect to issues of material composition, shape, and motion/position effects are all highlighted. For medical imaging, each type of technology will need specific materials and designs, and the physics and indications will be explored for each type. Health physics phantoms are concerned with some of the same issues such as material heterogeneity, but also unique issues such as organ-specific radiation dose from sources distributed in other organs. Readers will be able to use this book to select the appropriate phantom from a vendor at a clinic, to learn from as a student, to choose materials for custom phantom design, to design dynamic features, and as a reference for a variety of applications. Some of the information enclosed is found in other sources, divided especially along the three categories of imaging, therapy, and health physics. To our knowledge, even though professionally, many medical physicists need to bridge the three catagories described above.

Book Description
Drawing from a rich corpus of art works, including sarcophagi, tomb paintings, and floor mosaics, Patrick R. Crowley investigates how something as insubstantial as a ghost could be made visible through the material grit of stone and paint. In this fresh and wide-ranging study, he uses the figure of the ghost to offer a new understanding of the status of the image in Roman art and visual culture. Tracing the shifting practices and debates in antiquity about the nature of vision and representation, Crowley shows how images of ghosts make visible structures of beholding and strategies of depiction. Yet the figure of the ghost simultaneously contributes to a broader conceptual history that accounts for how modalities of belief emerged and developed in antiquity. Neither illustrations of ancient beliefs in ghosts nor depictions of afterlife, these images show us something about the visual event of seeing itself. The Phantom Image offers essential insight into ancient art, visual culture, and the history of the image.

Book Description
With almost 5 million copies sold 60 years after its original publication, generations of readers have now journeyed with Milo to the Lands Beyond in this beloved classic. Enriched by Jules Feiffer’s splendid illustrations, the wit, wisdom, and wordplay of Norton Juster’s offbeat fantasy are as beguiling as ever. “Comes up bright and new every time I read it . . . it will continue to charm and delight for a very long time yet. And teach us some wisdom, too.” --Phillip Pullman For Milo, everything’s a bore. When a tollbooth mysteriously appears in his room, he drives through only because he’s got nothing better to do. But on the other side, things seem different. Milo visits the Island of Conclusions (you get there by jumping), learns about time from a ticking watchdog named Tock, and even embarks on a quest to rescue Rhyme and Reason. Somewhere along the way, Milo realizes something astonishing. Life is far from dull. In fact, it’s exciting beyond his wildest dreams!

Book Description
Twin brothers discover their new home is also a portal--for an hour a day--to a parallel dimension in this spine-chilling middle-grade adventure, perfect for fans of The Mysterious Benedict Society Twelve-year-old twins Colm and Mal might look identical, but they’re different in just about every other way. The one thing they can agree on is that neither brother wants to move to Chicago for a fresh start with their mom two years after their dad’s death. The boys soon discover that their new apartment building, Brunhild Tower, is full of strange quirks: a mysterious Princess who warns them not to wander the building at midday, eerie sounds coming from the walls, and an elevator that’s missing a button for the thirteenth floor. Then one afternoon, that button appears, catapulting the brothers and their inquisitive new neighbor, Tamika, into a parallel dimension and a twin building stuck in time, where the spirits of all the former residents of Brunhild Tower live on, trapped by an ancient curse. Now, Colm, Mal, and Tamika must race against time to solve the mystery of the phantom tower—or risk spending an eternity as ghosts themselves.

Book Description
A powerful dissection of one of the fundamental problems in American governance today: the clash between presidents determined to redirect the nation through ever-tighter control of administration and an executive branch still organized to promote shared interests in steady hands, due deliberation, and expertise. President Trump pitted himself repeatedly against the institutions and personnel of the executive branch. In the process, two once-obscure concepts came center stage in an eerie faceoff. On one side was the specter of a "Deep State" conspiracyadministrators threatening to thwart the will of the people and undercut the constitutional authority of the president they elected to lead them. On the other side was a raw personalization of presidential power, one that a theory of "the unitary executive" gussied up and allowed to run roughshod over reason and the rule of law. The Deep State and the unitary executive framed every major contest of the Trump presidency. Like phantom twins, they drew each other out. These conflicts are not new. Stephen Skowronek, John A. Dearborn, and Desmond King trace the tensions between presidential power and the depth of the American state back through the decades and forward through the various settlements arrived at in previous eras. Phantoms of a Beleaguered Republic is about the breakdown of settlements and the abiding vulnerabilities of a Constitution that gave scant attention to administrative power. Rather than simply dump on Trump, the authors provide a richly historical perspective on the conflicts that rocked his presidency, and they explain why, if left untamed, the phantom twins will continue to pull the American government apart.

Book Description
The definitive social history of tuberculosis, from its origins as a haunting mystery to its modern reemergence that now threatens populations around the world. It killed novelist George Orwell, Eleanor Roosevelt, and millions of others-rich and poor. Desmond Tutu, Amitabh Bachchan, and Nelson Mandela survived it, just. For centuries, tuberculosis has ravaged cities and plagued the human body. In Phantom Plague, Vidya Krishnan, traces the history of tuberculosis from the slums of 19th-century New York to modern Mumbai. In a narrative spanning century, Krishnan shows how superstition and folk-remedies, made way for scientific understanding of TB, such that it was controlled and cured in the West. The cure was never available to black and brown nations. And the tuberculosis bacillus showed a remarkable ability to adapt-so that at the very moment it could have been extinguished as a threat to humanity, it found a way back, aided by authoritarian government, toxic kindness of philanthropists, science denialism and medical apartheid. Krishnan's original reporting paints a granular portrait of the post-antibiotic era as a new, aggressive, drug resistant strain of TB takes over. Phantom Plague is an urgent, riveting and fascinating narrative that deftly exposes the weakest links in our battle against this ancient foe.
