This two-volume introduction to differential geometry, part of Wiley''s popular Classics Library, lays the foundation for understanding an area of study that has become vital to contemporary mathematics. It is completely self-contained & will serve as a reference as well as a teaching guide. Volume 1 presents a systematic introduction to the field from a brief survey of differentiable manifolds, Lie groups & fibre bundles to the extension of local transformations & Riemannian connections. The second volume continues with the study of variational problems on geodesics through differential geometric aspects of characteristic classes. Both volumes familiarize readers with basic computational techniques.

One of two volumes which lay the foundations for understanding differential geometry. This work familiarizes readers with various techniques of computation.

This volume covers a diverse collection of protocols currently being used by the Toxoplasma research community, and also looks at innovative methods that are pushing the boundaries of possibilities. Chapters in this book discuss topics such as isolation and genotyping of Toxoplasma gondii strains; assessing rhoptry secretion in T. gondii; plate-based quantification of stimulated Toxoplasma egress; methods to study ocular toxoplasmosis; and metabolic analysis of Toxoplasma gondii tachyzoites. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.Cutting-edge and thorough, Toxoplasma gondii: Methods and Protocols is a valuable resource for students or groups starting off in the field, as well as laboratories interested in implementing the latest techniques described in the book.

Urban, Emil K.The second volume in this series continues the high standards set by the first. The three editors have followed the vision of the late Leslie Brown and organized a team of internationally known experts to help them produce an up-to-date and comprehensive work. This volume covers all birds found in Africa, from gamebirds to pigeons. In order to do justice to the ever increasing volume of publications on African birds and the wealth of material collated by the contributors, and to fulfil the aim of illustrating all main plumages of every species, the series has been expanded to six volumes, the first three to cover the non-passerines and the last three the passerines.As in Volume I, all species of birds found in Africa are covered, including migrants and vagrants. Resident birds are treated in full detail, with sections on their range and status, description, field characters, voice, general behaviour, food and breeding biology. Visitors are also given extensive coverage, with emphasis on their status and behaviour within Africa.These volumes are being acclaimed as the authority on the avifauna of Africa; they will remain as such for many years to come. The quality of the text and the beauty of the plates will assure them pride of place on the shelves of ornithologists and bird-watchers everywhere. Indeed, anyone with an interest in natural history or ecology will find here a source of much interest and enjoyment.

Leslie H. Brown (Editor), C. Hilary Fry (Editor), Stuart Keith (Editor), K. Newman (Editor), Kai Curry-Lindahl (Editor)Universally recognized as by far the most authoritative work ever published on the subject, The Birds of Africa is a superb reference with encyclopedic species texts, stunning paintings, detailed line drawings, and comprehensive bibliographies. This is the sixth volume in a set of seven, follows the standard taxonomic sequence and deals with songbirds from the babblers to starlings. A new introduction brings the reader up-to-date with recent developments in the series and includes an essay on aspects of biogeography illustrated through African birds. Overviews of the families are followed by genus summaries (with associated superspecies maps, where appropriate) and the species accounts themselves, organized under standard heading: Range and Status, Description, Field Characters, Voice, General Habits, Food, Breeding Habits, and Key References. Each species has a distribution map and many are illustrated with line drawings showing nests and behavior by Ian Willis. The texts are written by experts on the species and the editors themselves. There are 36 superb color plates by Martin Woodcock that illustrate all the plumages of all species covered in the volume. Full references to written and sound recorded material complete this authoritative coverage.

Urban, Emil K.Universally recognized as by far the most authoritative and comprehensive work ever published, Birds of Africa, Volume V is the second of four volumes to deal with the Passerine birds of the continent. The families treated fall into the following groups: thrushes, Old World warblers, Old World flycatchers, monarch flycatchers wattle-eyes and puffback flycatchers. The editors and artists have worked closely with nine other authors--all acknowledged experts on their bird families--to produce a superb reference in which encyclopedic texts on every species are complemented by accurate and detailed paintings and drawings of the birds themselves. Full bibliographies, acoustic references and indexes complete this marvelous reference.Key Features: * Continues the high quality of this well-regarded series * Provides the only comprehensive handbook treatment of African birds

Fry, C. HilaryBy far the most authoritative and comprehensive work ever published on the birds of Africa. The Editors and artists have worked closely with the 16 authors of this volume--all internationally acknowledged experts on their bird families--to produce encyclopaedic accounts of each species.This volume completes the non-passerines, dealing with all species occurring on the continent--residents and visitors alike--in the following families: parrots, turacos, cuckoos, owls, nightjars, swifts, colies, kingfishers and their allies, and woodpeckers and their allies. All are illustrated, and all known biological information is included. The passerines (songbirds) will be covered in four forthcoming volumes, already in preparation.
