ABSTRACT: Sand production onset and mass/rate predictions are difficult to validate in the field because the field sand production data are often unreliable. To overcome this difficulty recent research has concentrated in representing as realisticall

Following the proposal by Muller, Berlinger and Tosatti on a possible coherent quantum regime in SrTiO3 below 40 K we have performed elastic measurements to look for possible related anomalies in a near-monodomain crystal. The known anomalies related

A single crystal of La 1.88 Sr 0.12 CuO 4 was studied by means of X-ray and neutron diffraction experiments and elastic measurements. The obtained data show that this compound undergoes a tetragonal to orthorhombic phase transition at around 260 K. T

Abstract A system for acoustic velocity and static Young's modulus measurements on small (mm-size) shale samples is presented. The equipment has been tested on both soft and hard shales, including cuttings. Even though more experimental testing, must
