Experience the first in the epic series featuring the brave members of Omega Squad—an elite team of clone commandos—fighting to protect the Galactic Republic. On a mission to sabotage a chemical weapon research facility on a Separatist-held planet, four clone troopers operate under the very noses of their enemies. The commandos are outnumbered and outgunned, deep behind enemy lines with no backup–and working with strangers instead of trusted teammates. Matters don’t improve when Darman, the squad’s demolitions expert, gets separated from the others during planetfall. Even Darman’s apparent good luck in meeting an inexperienced Padawan vanishes once Etain admits to her woeful naivety. For the separated clone commandos and stranded Jedi, a long, dangerous journey lies ahead, through hostile territory brimming with Trandoshan slavers, Separatists, and suspicious natives. A single misstep could mean discovery . . . and death. It’s a virtual suicide mission for anyone–anyone except Republic Commandos.

In this thoroughly revised and updated third edition of Contact Lens Practice, award-winning author, researcher and lecturer, Professor Nathan Efron, provides a comprehensive, evidence-based overview of the scientific foundation and clinical applications of contact lens fitting. The text has been refreshed by the inclusion of ten new authors – a mixture of scientists and clinicians, all of whom are at the cutting edge of their specialty. The chapters are highly illustrated in full colour and subject matter is presented in a clear and logical format to allow the reader to quickly hone in the desired information. - Ideal for an optometrist, ophthalmologist, orthoptist, optician, student, or work in the industry, this book will serve as an essential companion and guide to current thinking and practice in the contact lens field. - Highlights of this edition include a new chapter on myopia control contact lenses, as well are completely rewritten chapters, by new authors, on keratoconus, orthokeratology, soft and rigid lens measurement and history taking.

Pulitzer Prize-winning author and astronomer Carl Sagan imagines the greatest adventure of all—the discovery of an advanced civilization in the depths of space. In December of 1999, a multinational team journeys out to the stars, to the most awesome encounter in human history. Who—or what—is out there? In Cosmos, Carl Sagan explained the universe. In Contact, he predicts its future—and our own.

This book summarizes current understanding of the scientific, clinical, and technical issues surrounding the use of contact lenses. It discusses the special occupational conditions experienced by military personnel, particularly in extreme environments, that give rise to the question of whether or not to use contact lenses. Experts in optometry, ophthalmology, visual psychophysics, and engineering describe recent developments in design and use; and representatives of the military services provide examples of actual situations in aerospace settings. Considerations in Contact Lens Use Under Adverse Conditions will be of particular interest to those involved in the design of contact lenses and those responsible for occupational safety and health matters in the private sector.

This book is a completely revised and rewritten edition of "Electric Contacts Handbook" published in 1958. A large number of new in vestigations are considered, and many of the basic theories are revised in detail and even in general. The body of information had to be limited as it was not advisable to increase the volume of the book. In particular, no attempt was made to cover all of the practical applications. They appear as examples following concentrated explanations of basic phenomena. As in several branches of technology, the solutions of problems ari sing in the field of electric contacts involve insight into various disci plines of physics. It is feit that reviews of some of those topics, especi ally adapted to electric contact phenomena, are welcome to many readers. For example, chapters have been devoted to the structure of carbon, the band theory of electric conduction in solids, certain pro blems in statistics, and the theory of the electric arc. As regards arc problems, new ideas have been introduced. In order to make the main text less cumbersome, such reviews are presented as appendices. Throughout this edition, the mksa-unit system is used in accord with the latest recommendation for standardization of units in scientific and technical writings. The chapter "History of Early Investigations on Contacts" forming Part IV in the preceding edition of 1958 has not been repeated in this book.

This volume introduces and explains an eye-opening treatment for correcting nearsightedness and related vision problems naturally and neurologically. The author presents his methodology on neurologically correcting primary refractive errors in the mild and moderate myopic range. Ortho C (or orthoculogy, which is Latin for "correcting the whole eye") is a natural treatment, requiring no alteration to the cornea. Key features of the book: • Introduces a neurological and natural treatment for the correction of nearsightedness • Presents many case studies showing the effectiveness of this treatment, based on the author’s 30+ years of research • Provides step-by-step instructions for designing lenses to suit the need, determining the sequence of wear, and conducting resistance tests • Grants readers the right to apply Ortho C to treat any patients with mild and moderate myopia, anisometropia, or compound astigmatism.
