Journal of Perioperative Practice, 2007
Surgeons have always been ready to adapt advances in technology into their practice. The discovery by Wilhelm Roentgen of X-rays in 1885 was applied within weeks of its publication to the diagnosis of fractures and the location of foreign bodies. The development of the electric light bulb by Edison enabled Max Nitze, Professor of Urology in Berlin, to ...

The Intermediate Filament Systems in the Eye Lens
2004Publisher Summary This chapter describes the basic methods to purify important lens fractions and to track the distribution of IF proteins in the eye lens and their associated proteins. It also provides the description of the methods used for the preparation, sectioning, and examination of eye lenses.

The Journal of the Acoustical Society of America, 1994
An acoustic lens system is constructed so that at least one surface of acoustic lenses constituting the acoustic lens system is an aspherical surface, which has such a shape that curvature moderates progressively in separating from the axis of the acoustic lens system, and an acoustic beam stop is provided therein.

The change in curvature of a wave front by a lens can be considered in two stages: first the change as the wave front enters the lens and then the change as it leaves. Consider now the passage of a wave front from a medium of index µ p , where its radius of curvature is p, into a medium of index µ q , the boundary surface itself having radius of ...

Reports on Progress in Physics, 1956
After an introductory discussion of the elementary aberration theory of corrected optical systems, and some consideration of new optical materials and processes, recent forms of optical imaging systems are described; most of these are systems of spherical refracting surfaces; aspheric and reflecting systems are also included.
