Book Description
This book is a synopsis of modern deep-field astronomy, based on the powerful telescopes and instruments developed in recent years. It is organized along topical themes, such as the extragalactic background radiation at different wavelengths, the evolution of galaxies, the history of star formation, the nature of absorbers, the reionization of the intergalactic medium, the validity of photometric redshifts, gravitational lensing, and clustering of galaxies. Stellar and substellar objects were not neglected, however, and one session was devoted to nearby bodies such as trans-Neptunian solar system objects, brown dwarfs, and stars with special characteristics.

Book Description
Mangrove rice farming on West Africa's Rice Coast was the mirror image of tidewater rice plantations worked by enslaved Africans in 18th-century South Carolina and Georgia. This book reconstructs the development of rice-growing technology among the Baga and Nalu of coastal Guinea, beginning more than a millennium before the transatlantic slave trade. It reveals a picture of dynamic pre-colonial coastal societies, quite unlike the static, homogenous pre-modern Africa of previous scholarship. From its examination of inheritance, innovation, and borrowing, Deep Roots fashions a theory of cultural change that encompasses the diversity of communities, cultures, and forms of expression in Africa and the African diaspora.

Book Description
This book was originally published in 1957. During the First World War, German use of unrestricted submarine warfare, supported by extensive mining and surface raids, very nearly forced Britain out of the war in 1917. The island’s heavy dependence on seaborne supplies was gravely threatened again in 1939, supplemented this time by air attacks on shipping. After the war, Commanders Waters and Barley wrote a Naval Staff History which has long been recognised as an authoritative study of the impact of the German campaign and its ultimate defeat by Britain and her allies. It remains an indispensable basis for any serious study of the Battle of the Atlantic and has here been updated and revised by Dr Grove, who also contributes a perceptive introduction outlining its significance.

Book Description
Awarded the American Astronomical Society (AAS) Rodger Doxsey Travel Prize, and with a foreword by thesis supervisor Professor Shardha Jogee at the University of Texas at Austin, this thesis discusses one of the primary outstanding problems in extragalactic astronomy: how galaxies form and evolve. Galaxies consist of two fundamental kinds of structure: rotationally supported disks and spheroidal/triaxial structures supported by random stellar motions. Understanding the balance between these galaxy components is vital to comprehending the relative importance of the different mechanisms (galaxy collisions, gas accretion and internal secular processes) that assemble and shape galaxies. Using panchromatic imaging from some of the largest and deepest space-based galaxy surveys, an empirical census of galaxy structure is made for galaxies at different cosmic epochs and in environments spanning low to extremely high galaxy number densities. An important result of this work is that disk structures are far more prevalent in massive galaxies than previously thought. The associated challenges raised for contemporary theoretical models of galaxy formation are discussed. The method of galaxy structural decomposition is treated thoroughly since it is relevant for future studies of galaxy structure using next-generation facilities, like the James Webb Space Telescope and the ground-based Giant Magellan Telescope with adaptive optics.
