  • 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 move....

  • 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. ...

  • What is it? RADAR to detect position of objects. Counter measures 1. ECM ( e.g. chaff cartridges) 2. Non ECM. Avoiding detection and innovating deception . RCS reductions, acoustics, thermal and other EM emissions.How is it achieved. Absorbs radar waves or deflects to other directions. Minimizes heat and other emissions from engine and other spots. Makes difficult to detect except closely.Vehicle shape and structure.Smooth edges maximum radio wave reflectors.
