Gemmology is a text for students preparing for the Gemmological Association's Preliminary and Diploma examinations. The book is more expansive and up-to-date than the author's earlier book, Beginner's Guide to Gemmology. The book deals with the practical and theoretical sides of gemmology. Tracing the background and science of gemmology, the book covers the gem material, geological formation, and occurrence of gemstones on the earth. The composition of gemstones from the atoms, elements, molecules, and compounds comprising them is analyzed, and the relationship between chemical composition and durability of the stone is explained. The basics of crystallography is mentioned as a tool toward understanding gemmology after which cleavage, parting, and fracture are done. A gemstone's durability and hardness and how the latter influences engineering tests and the mining techniques are compared. An important test technique to identify unmounted stones is the measure of specific gravity using displacement measurement methods and hydrostatic methods. After more descriptive details are given in identification of gemstones, whether these are synthetic or simulants, through a comprehensive explanation of the materials found in these other gemstones, the fashioning, through shaping or polishing, of gemstones is explained. Emphasis is given on the critical angle in which light rays pass in different rock densities, and then the cutting styles, gemstone polishing, and grading are discussed. Students studying for the Gemmological Association's Preliminary and Diploma examinations, jewelers, lapidarists, and diamond cutters, as well as those engaged in the hobby of gemmology, will find this book helpful and full of information toward their endeavors and hobbies.

The book describes a system for visual surveillance using intelligent cameras. The camera uses robust techniques for detecting and tracking moving objects. The real time capture of the objects is then stored in the database. The tracking data stored in the database is analysed to study the camera view, detect and track objects, and study object behavior. These set of models provide a robust framework for coordinating the tracking of objects between overlapping and non-overlapping cameras, and recording the activity of objects detected by the system.

Since the publication of the second volume of Comparative Psychology by Warden, Warner, and Jenkins (1940), there has not been a comprehensive review of invertebrate learning capacities. Some high-quality reviews have appeared in various journals, texts, and symposia, but they have been, of necessity, incomplete and selective either in terms of the phyla covered or the phenomena which were reviewed. Although this lack has served as a stimulus for the present series, the primary justification is to be found in the resurgence of theoretical and empirical interests in learning capacities and mechanisms in simpler systems of widely different phylogenetic origin. Intensive research on the physiological basis of learning and memory clearly entails exploration of the correlations between levels of nervous system organization and be havioral plasticity. Furthermore, the presence of structural-functional differ entiation in ganglionated systems, the existence of giant, easily identifiable cells, and the reduced complexity of structure and behavior repertoires are among the advantages of the "simple systems" strategy which have caused many neuroscientists to abandon their cats, rats, and monkeys in favor of mollusks, leeches, planaria, crayfish, protozoa, and other invertebrate preparations. Behavioral research continues to reveal remarkable capacities in these simple organisms and encourages us to believe that the confluence of the invertebrate learning data with the more voluminous vertebrate litera ture will contribute substantially to the enrichment of all of the neurobe havioral sciences.

"In a near-future Southern city, everyone is talking about a new experimental medical procedure that boasts unprecedented success rates. In a society plagued by racism, segregation, and private prisons, this operation saves lives with a controversial method--by turning people white. Like any father, our unnamed narrator just wants the best for his son Nigel, a biracial boy whose black birthmark is getting bigger by the day. But in order to afford Nigel's whiteness operation, our narrator must make partner as one of the few black associates at his law firm, jumping through a series of increasingly absurd hoops--from diversity committees to plantation tours to equality activist groups--in a tragicomic quest to protect his son. This electrifying, suspenseful novel is, at once, a razor-sharp satire of surviving racism in America and a profoundly moving family story. In the tradition ofRalph Ellison's Invisible Man, We Cast a Shadow fearlessly shines a light on the violence we inherit, and on the desperate things we do for the ones we love"--

A deeply moving memoir that confronts the defining trauma of the twentieth century, and its effects on a father and son. In 1939, Jonathan Lichtenstein's father Hans escaped Nazi-occupied Berlin as a child refugee on the Kindertransport. Almost every member of his family died after Kristallnacht, and, upon arriving in England to make his way in the world alone, Hans turned his back on his German Jewish culture. Growing up in post-war rural Wales where the conflict was never spoken of, Jonathan and his siblings were at a loss to understand their father's relentless drive and sometimes eccentric behavior. As Hans enters old age, he and Jonathan set out to retrace his journey back to Berlin. Written with tenderness and grace, The Berlin Shadow is a highly compelling story about time, trauma, family, and a father and son's attempt to emerge from the shadows of history.
