Asthenosphere A region of the earth’s upper mantle at a
depth of approximately 75–150 km, characterized by
low mechanical strength, attenuation of seismic shear
waves, and partial melting. The term was coined in
the 1910s by geologist Joseph Barrell to describe the
zone in which isostatic adjustment occurs and basaltic
magmas are generated. With the development of plate
tectonics in the 1960s, the asthenosphere is now un-
derstood as the plastic zone over which the rigid plates
This book collects chapters on different theoretical and experimental aspects of photonics crystals for Nanophotonics applications. It is divided in two parts - a theoretical section and an experimental and applicative section.
As the full horror of the Asian tsunami sinks in, the reactions
of scientists echo those of the population as a whole. These
range from a sense of hopelessness in the face of nature’s
power to concern for the victims and a determination that their
suffering should be addressed.
In the present paper the governing equations for dynamical analysis of corrugated cross-ply laminated composite plates in the form of a sin wave are developed based on the Kirchoff-Love’s theory and the extension of Seydel’s technique. The problems of natural vibration and forced vibration of a plate with various boundary conditions are studied. Effects of factors as geometry dimensions, order of laminate as well as waved-amplitude on frequency of natural vibration, amplitude of forced vibration of the corrugated cross-ply laminated composite plates are also analysed. ...
