Luck always runs in sets of threes. It can be good luck or it can be bad luck, but luck always runs in sets of three." This exciting sequel follows the continuing adventures of Jon and Sara Kline, now apprentice time travelers. An unexplained burp in the timeline sends the two time travelers back on a mission to find out why history changed. Within their mini-adventure, they discover the gateway man. He is a time traveler from the future with a superior time machine. The man has totally evil intentions. He is stealing objects from the past without regard for the consequences to history. Consequently, Jon and Sara's history is flip-flopping from bad to worse. Two time machines are one too many and the duo's time traveling career depend upon stopping the gateway man. The exciting conclusion is literally out of this world.
There are no paradoxes in time, only looped back versions of history we call alternate realities. Under the sands of Egypt and near the Sphinx, two amateur archeologists make a most unexpected find. Instead of a Pharaohs tomb, they uncover an ancient, dust-choked room filled with books, computers and modern equipment. The tomb is least five thousand years old. Slowly, the young spelunkers unravel the mystery of the apparent paradox. They also discover a working Time Machine. Time itself has taken an alternate course. The powerful European Trade Confederation bullies a depressed, non-nuclear United States. The British Empire controls their colonial possessions with an iron fist. Time for the young discoverers is running out. Global events are slowly colliding where retaining the secret of their discovery is almost impossible. A race develops to get the secrets of time travel out of the country.
In Ecotoxicology: A Hierarchical Treatment, 20 recognized experts from around the world identify and present the fundamental concepts of ecotoxicology at the biological level central to their own research. Superbly organized, the book proceeds sequentially by chapter from the chemical to cellular to the ecosystem level, making it easy to read, understand, and use. Specifically, each author identifies important hypotheses, paradigms, "false" paradigms, or new techniques in his or her research area. As a result, this book is a stimulating progressive treatment of ecotoxicology at all levels of organization. Each chapter draws mechanistic interpretation from the next lower level and attempts to predict effects at the next higher level. This innovative approach underscores ecotoxicology's potential for development into a new discipline and makes Ecotoxicology: A Hierarchical Treatment the definitive reference at this crucial juncture.
This book explores the face from a number of perspectives: evolutionary, embryonic, developmental, postnatal, anatomic, physiologic, dysmorphic, genetic, surgical psychosocial, sociocultural, symbolic, and artistic. These are diverse fields, yet they are brought together here to help form an integrated understanding and appreciation of this fascinating subject. Like images seen in a kaleidoscope, faces are infinitely complex and beautiful. They are woven into our daily lives, our dreams, and our memories."--BOOK JACKET.
