Hamiltonian Perturbation Solutions for Spacecraft Orbit Prediction


Book Description

"Analytical solutions to the orbital motion of celestial objects have been nowadays mostly replaced by numerical solutions, but they are still irreplaceable whenever speed is to be preferred to accuracy, or to simplify a dynamical model. In this book, the most common orbital perturbations problems are discussed according to the Lie transforms method, which is the de facto standard in analytical orbital motion calculations"--Print version, page 4 of cover.




Diseases of the Orbit


Book Description

Now thoroughly revised, this Second Edition text focuses on a case-based learning approach that features decision-making information presented in algorithmic format. Sections covered are the anatomy of the orbit, pathophysiologic and anatomic principles in classifying, diagnosing and investigating orbital disease, diseases of the orbit, and the management of those diseases. New topics include orbital ultrasound, gamma scanning, magnetic resonance imaging, incidence of lesions by location, management of complex vascular lesions, granulomatous inflammations of the orbit, and orbital atrophy. A conceptual model is presented and a new classification scheme discussed. Several chapters have been updated and illustrations are plentiful.

Exobiology in Earth Orbit


Book Description

This volume gives a status report on the scientific investigations which can be undertaken in the field of exobiology using instruments in Earth orbit. A brief list of these recommended experiments is given here. Those listed for the Observational Exobiology section are in order of decreasing priority as determined by a consensus of the Workshop members. Otherwise, no priorities are implied by the order in which the experiments are listed. Observational Exobiology: 1. Search for extrasolar planetary systems, 2. Study star-forming regions in the galaxy--analogs for the solar nebula, 3. Study comets, asteroids, Titan, and the giant planets in our own solar system, 4. Study the organic chemistry of interstellar molecular clouds. Cosmic Dust Collection: 1. Develop and implement capture techniques which preserve biogenic material, 2. Develop and implement techniques to determine the orbits of dust particles, 3. Refine laboratory methods for the analysis of small particles. In Situ Experiments: 1. Study the formation, condensation, aggregation, and surface chemistry of suspended dust grains, 2. Create, release, and monitor an artificial comet in space, 3. Determine the viability of microorganisms in space.

Diseases and Disorders of the Orbit and Ocular Adnexa E-Book


Book Description

Drawing from the knowledge and expertise of more than 70 contributing international experts, Diseases and Disorders of the Orbit and Ocular Adnexa thoroughly covers the state of the art in orbital and periocular disease from the perspective of a variety of specialties. Clearly written and profusely illustrated, it covers the clinical presentation, pathophysiology, natural history, and management alternatives of disease processes affecting the orbit, eyelids, lacrimal system, and upper face. With a singular focus on the diagnosis and management of orbital and ocular adnexal disease, this authoritative text gives you the information you need to excel both in practice and on exams in the specialty of ophthalmic plastic and reconstructive surgery. Offers an in-depth and thorough approach to the pathophysiology of oculoplastics and orbital disease, incorporating the perspectives of numerous specialties – all in one convenient volume. Uses an easy-to-follow, templated format throughout so you can find what you need quickly. Covers new information not included in other texts, such as antibody testing in dysthyroid conditions and a rapidly emerging array of targeted immunosuppressive medications for the treatment of inflammatory orbital disease. Includes hot topics such as the classification and management of orbital inflammatory disease; vascular neoplasms and malformations; periocular dermatology; burn management; facial paralytic disease; and the pathogenesis, evaluation and management of lymphoproliferative disease. Features more than 1,200 high-quality clinical, imaging, and histological illustrations that provide clear visual examples of orbital disease. Written by an international team of experts from five continents (across multiple specialties including ophthalmology, dermatology, burn management, plastic surgery, otolaryngology, endocrinology, and pathology) led by Dr. Aaron Fay and Dr. Peter J. Dolman.
