Описание: Choosing and Using a Refracting Telescope has been written for the many amateur astronomers who already own, or are intending to purchase, a refracting telescope – perhaps to complement their existing arsenal of larger reflecting telescopes – or for the specialist who requires a particular refractor for serious astronomical applications or nature studies.Four hundred year ago, during the winter of 1609, a relatively unknown Italian scientist, Galileo Galilei designed a spyglass with two crude lenses and turned it skyward. Since then, refractors have retained their dominance over all types of reflector in studies of the Moon, planets and double stars because of the precision of their optics and lack of a central obstruction in the optical path, which causes diffraction effects in all commercially-made reflectors.Most mature amateur astronomers got started with a 60mm refractor, or something similar. Thirty years ago, there was little choice available to the hobbyist, but in the last decade long focus crown-flint achromats have moved aside for some exquisitely crafted apochromatic designs offered by leading commercial manufacturers. There has been a huge increase in the popularity of these telescopes in the last few years, led by a significant increase in the number of companies (particularly, William Optics, Orion USA, StellarVue, SkyWatcher and AstroTech) who are now heavily marketing refractors in the amateur astronomical magazines.In Choosing and Using a Refracting Telescope, well-known observer and astronomy writer Neil English celebrates the remarkable history and evolution of the refracting telescope and looks in detail at the instruments, their development and their use. A major feature of this book is the way it compares not only different classes of refractor, but also telescopes of each class that are sold by various commercial manufacturers. The author is perhaps uniquely placed to do this, having used and tested literally hundreds of different refracting telescopes over three decades.Because it includes many diverse subjects such as imaging with consumer-level digital cameras, imaging with webcams, and imaging with astronomical CCD cameras – that are not covered together in equal depth in any other single volume – Choosing and Using a Refracting Telescope could become the ‘refractor bible’ for amateur astronomers at all levels, especially those who are interested in imaging astronomical objects of every class.
Описание: This is the first book to explore all central issues surrounding the relationship between the film-image and philosophy. It tackles the work of particular philosophers of film (A iA ek, Deleuze and Cavell) as well as general philosophical positions (Cognitivist and Culturalist), and analyses the ability of film to teach and create philosophy.

Описание: Spurred by PRK, LASIK, and other laser-based techniques, refractive surgery is growing at an explosive rate. Within the next decade, laser procedures alone will form a billion-dollar market with more than 500,000 new operations per year.This comprehensive new work-with nearly 300 full-color illustrations-brings the ophthalmologist up-to-date on recent advances in the field, and shows how to use refractive techniques effectively in daily practice. The book examines all major refractive methods, from incisional techniques to laser and lamellar procedures, and in each case provides complete information on patient selection, instrumentation, operative technique, pitfalls and complications, and postoperative management. This is a well-balanced, complete overview of each refractive procedure, thoroughly referenced to maximize usefulness for all ophthalmologists.

Описание: This comprehensive text is dedicated to the refractive management of common ametropias and presbyopia. Symptoms and signs of each type of ametropia and presbyopia are presented, and guidelines for prescribing corrective lenses are offered. Over 40 clinical cases are used to illustrathe clinical decision making process. A discussion section for each case describes the rationale for specific management approaches.
Описание: Focuses on electronic structure and properties of superhard and strong refractory materials.

Описание: The second volume of "Cataract and Refractive Surgery" in the Essentials in Ophthalmology series provides new, clinically relevant information on cataract and refractive surgery. The chapters discuss new techniques and technology with an emphasis on areas that are rapidly evolving and essential to sophisticated clinical practice. Topics include:New IOL technologyCataract surgery in challenging cases, such as loose zonules and small pupilsAdvanced IOL calculation methodsCustomized corneal refractive surgery, including LASIK, Epi-LASIK and femtosecond laser technologyComplications of excimer laser surgery and intraocular refractive lens technology (phakic IOLs, refractive lens exchange)Corneal implantsAccommodative and pseudo-accommodative IOLs to correct presbyopia.This list clearly reflects the expanding interrelationship of cataract and refractive surgery. Cataract patients expect outstanding refractive results with expanded visual capabilities and minimal complications. Likewise, many refractive surgical patients undergo lenticular surgical procedures and all ultimately expect near-perfect outcomes from their cataract procedures. This book will help clinicians provide the best results for their cataract and refractive surgical patients.

Описание: This third edition of a standard text provides complete coverage of the use of cryptographic protocols which establish a series of steps that must be taken before any type of secret transmission can be completed. The book shows the reader how the various parties to the transaction establish their cryptographic identities or keys. It covers many of the cryptographic tools used in network security along with topic such as copyright protection techniques and public key infrastructure. The book is a text for senior graduate courses introducing cryptography and is also a useful reference for professionals interested in network security and cryptographic protocols.
