A new type of optical element is presented. The presented element substitutes both a thin-film plane polarizer and a narrow-band interference filter for the selected wavelength. A comparative analysis of the basic parameters for the new...

By coupling to cholesterol, Hedgehog can be anchored to the cells where it is made, yet to act as a morphogen, it must be able to move away from its source. Novel genes have now been identified that control the release and dispersal of ...

A patient with a so-called ‘butterfly vertebra’ is presented. Radiography, including computed tomography, is shown. The embryology and pathogenesis of the vertebral column with respect to vertebral abnormalities are discussed, with ...

1.1. Western Grey Kangaroos generally inhabit more arid and hotter regions than Eastern Greys.2.2. Ears from Western Greys are significantly thinner, less furred and have smaller, thinner hairs than those from Eastern Grays.3.3. Ears ma...

Solutions to stochastic differential equations depends on the method of approximation. In this paper we give a very simple demonstration that ordinary differential equations, too, exhibit this kind of behavior when the coefficients are ...

It is now apparent that ion beams have a role to play in the machining and polishing of optical components. In this paper we review some of the applications which have been reported so far and also consider future Air Max 90 Essential a...

Fractal interpolation functions provide a new method to model experimental data. Nike Air Force 1 Dalla and Drakopoulos got some conditions that a vertical scaling factor must obey to model effectively an arbitrary function (J. Approx. ...

We characterize local Noetherian domains R   with infinite residue field which admit only finitely many star (prime) operations. We further show that a positive integer n   is equal to the number of star operations on such an ...

Twenty patients with chronic pulmonary histoplasmosis have been studied pathologically, clinically, roentgenologically and mycologically. The disease, which is most commonly seen in middle-aged men is, generally progressive and fatal un...

The use of a silicon photodiode array as a multi-wavelength detector which allows the recording of complete UV spectra for each component in the effluent from liquid chromatography is described. This detector gives noise levels of the o...
