Ранее астрономы считали, что этот огромный и относительно тусклый остаток сверхновой, которая вспыхнула примерно 5000-8000 лет назад, находится на расстоянии около 2500 световых лет от Земли, однако исследования, которые выполнили космический телескоп 'Хаббл', показали, что туманность находится гораздо ближе - на расстоянии всего 1470 световых лет. ...

Authors: V.A. Marsakov , T.V. Borkova , . ...

. The elementary methods (that is, the use of real analysis vs. complex analysis) have a long history from Chebyshev to modern times. They lead to great achievements, due to Erdos, Selberg, Bombieri, etc. I recently started a thorough study of these methods, in order to understand their scope. In the talk, I will give a quick survey of this field, and some new observations. Go to the Laboratoire Poncelet home page. Site design by Paul Zinn-Justin

... Introduction: E-, M- and S-type asteroids are widely considered as remnants of differentiated parent bodies; specifically, Ms might have been their cores [e. g., 1, 2]. The conviction is based on the visible-range albedo (medium to high) and overall spectral curves (slightly reddish to red) of the small planets corresponding to these of metal iron and igneous silicate assemblages. ... It seems the spectral features superimpose to the spectral characteristics of metal iron and igneous silicates. ...

The history of science of composites, which started with the development of nano-structured nano-structured fibres, those being of carbon and boron, has provided us with a continuous row of the examples of close relationships between composite technologies and nanotechnologies. Nanostructures of fibres, matrix and fibre/matrix interfaces determine unique properties of the composites. ... The author hopes that the continuation in a form of a new advance in the field of composites will follow. ...
