Part detective trail, part love affair and pure story telling at its best.

In 1990 an expedition of Cambridge scientists arrived at the Plains of Nechisar, tucked between the hills of the Great Rift Valley in the Gamo Gofa province in the country of Ethiopia. On that expedition, 315 species of birds were seen; 61 species of mammal and 69 species of butterfly were identified; 20 species of dragonflies and damselflies; 17 reptile species were recorded; three frog species were filed; plants were listed. And the wing of a road-killed bird was packed into a brown paper bag.

It was to become the most famous wing in the world.

When the specimens finally arrived at the British Natural History Museum in Tring it set the world of science aflutter. It seemed that the wing was unique, but they questioned, can you name a species for the first time based only on the description of a wing, based on just one wing?

After much to and fro, confirmation was unanimous, and the new species was announced, Nechisar Nightjar, Caprimulgus solala, (solus:only and ala:wing). And birdwatchers like Vernon began to dream.

Twenty-two years later an expedition of four led by Ian Sinclair set off to try to find this rarest bird in the world.

Vernon R.L. Head captivates and enchants as he tells of the adventures of Ian, Dennis, Gerry and himself as they navigate the wilderness of the plains, searching by spotlight for the elusive Nechisar Nightjar.

This remarkable collection of birding stories, written by some of our most intrepid bird observers, will convert a new generation of South African ornithologists and watchers of wilderness.

Birds and their names sing from the pages; owls, Shoebills, sandgrouse, Hooded Pittas, Rhinoceros Hornbills, Brown Kiwis, Rock Doves, Cape Eagle Owls, Greater Flameback woodpeckers, Inaccessible Island Rail, Superb and Beautiful Sunbird, Violet Turaco and the African Crowned Eagle.

From the bestselling author of The Search for the Rarest Bird in the World comes On That Wave of Gulls. An audacious novel, the tale is told by three characters – an architect, a Khoisan vagrant and a seagull, all of whom recount their lives in Cape Town.

Hieronymus Vos is an overweight, white architect, recently fallen on hard times, and married to a beautiful, black British-Caribbean woman. Although he hates the ocean, his practice has, until recently, been doing very well by designing glitzy millionaires’ mansions on the Atlantic Seaboard. Pooi is a homeless man, recently arrived from the Kalahari, with a patchy grip on reality. He thinks he is the moon and wants to teach himself to swim so that he can reach Robben Island and fulfil a promise. The third narrator is Calypso, a female seagull who needs to find a mate and lay an egg to pass on her legacy and her identity.

On That Wave of Gulls is a shrewd and lyrical tour de force by a natural storyteller. By times heartbreaking and thrilling, this unforgettable novel propels the author into the lives of the novel’s three main characters, throwing light on living and being in Cape Town – a Cape Town that is part wilderness, part glamorous high-rise developments, part ocean. Their interactions are at times fleeting, at times profound, and behind them lies the joy, pain and tragedy of living at the southern tip of Africa.

The Finite Element Method for Fluid Dynamics offers a complete introduction the application of the finite element method to fluid mechanics. The book begins with a useful summary of all relevant partial differential equations before moving on to discuss convection stabilization procedures, steady and transient state equations, and numerical solution of fluid dynamic equations.

The character-based split (CBS) scheme is introduced and discussed in detail, followed by thorough coverage of incompressible and compressible fluid dynamics, flow through porous media, shallow water flow, and the numerical treatment of long and short waves. Updated throughout, this new edition includes new chapters on:

Fluid-structure interaction, including discussion of one-dimensional and multidimensional problems.

Biofluid dynamics, covering flow throughout the human arterial system.

Focusing on the core knowledge, mathematical and analytical tools needed for successful computational fluid dynamics (CFD), "The Finite Element Method for Fluid Dynamics" is the authoritative introduction of choice for graduate level students, researchers and professional engineers.
A proven keystone reference in the library of any engineer needing to understand and apply the finite element method to fluid mechanics. Founded by an influential pioneer in the field and updated in this seventh edition by leading academics who worked closely with Olgierd C. Zienkiewicz. Features new chapters on fluid-structure interaction and biofluid dynamics, including coverage of one-dimensional flow in flexible pipes and challenges in modeling systemic arterial circulation.

Manufacturing Technology, Volume 1 provides a comprehensive introduction to the principles and practice of engineering manufacturing processes. This third edition has been written, updated and expanded to reflect the current requirements of the Advanced GNVQ Engineering syllabus as well as BTEC NC/D engineering specifications. As such it also forms an ideal introduction to the subject for first-year degree courses in engineering. Topics covered include: alteration of shape, tooling, toolholding and workholding, kinematics of manufacturing equipment, computer numerical control (CNC), assembly, fabrication (including plastics), heat treatment, finishing, quality control, manufacturing relationships, and health and safety at work. This book leads the reader naturally onto the companion volume Manufacturing Technology, Volume 2, intended for those studying engineering manufacture at a more advanced level such as HNC/D and first/second-year engineering degree courses. The broad and in-depth coverage of this two-volume approach ensures that these texts not only satisfy the requirements of technician students up to the highest level but also provide an excellent technical background for undergraduates studying for a degree in mechanical engineering, manufacturing engineering and combined engineering.

From New York Times bestselling author R.L. Stine, the master of horror for young readers, comes ten new stories that are sure to leave you shivering. A boy who hates bugs starts to see them everywhere. A basketball player's skin starts to almost drip off his hands--but no one else can see it. Three friends find a hole in the ground that just gets bigger, and bigger, and bigger... And each story is introduced by Stine himself, providing a personal touch sure to delight fans. Laced with Stine's signature humor and a hefty dose of nightmarish fun, Stinetinglers is perfect for fans of Scary Stories to Tell in the Dark and Stine's own Goosebumps books. These chilling tales prove that Stine's epic legacy in the horror genre is justly earned. Dive in, and beware: you might be sleeping with the lights on tonight!

Words have determinable sense only within a complex of unstated assumptions, and all interpretation must therefore go beyond the given material. This book addresses what is man's place in the Aristotelian world. It also describes man's abilities and prospects in managing his life, and considers how far Aristotle's treatment of time and history licenses the sort of dynamic interpretation of his doctrines that have been given. The ontological model that explains much of Aristotle's conclusions and methods is one of life-worlds, in which the material universe of scientific myth is no more than an abstraction from lived reality, not its transcendent ground.
