the effect of mixing on rheological behavior of 6% wt epoxy-clay nanocomposites was studied. the mixing processes were carried out by low shear mixer, homogenizer and ultrasonic and combination of different mixing techniques at medium and maximum power. all these methods led to intercalated structure. the xrd results showed that the ultrasonic has the best effect on dispersion while a low shear...

determination of boundary surface structures is commonly used for data interpretation. horizontal and vertical derivatives are useful tool for determining the edges boundary. using horizontal and vertical derivative in signal analysis method; that is effective method for interpretation of edges boundary, have been used commercially.in acquisition potential field data, using different methods of...

Abstract We study the effects of a massive field with continuous spectrum (continuum isocurvaton) on inflationary bispectrum in squeezed limit. As concrete example, we extend quasi-single inflation model to include continuum isocurvaton well-motivated spectral density from extra dimensions and focus contribution single exchange. In contrast usual case without spectrum, amplitude has damping fea...
