We present experimental evidence that pressure solution creep does not establish a steady-state interface microstructure as previously thought. Conversely, pressure solution controlled strain and the characteristic length scale of interface microstructures grow as the cubic root of time. Transient creep with the same scaling is known in metallurgy (Andrade creep). The apparent universal scaling...
b a c k ground: csf is a clear liquid that its mechanical properties are to a large extent similar to water properties. regarding the lack of a numerical index for diagnosis of diseases resulting from increased csf pressure such as hydrocephalus, evaluation of hydrodynamic conditions of csf in cerebral ventricular system is of great importance. methods: at first, the diagram of velocity in sylv...
The wavelength-dependent aerosol extinction in the 800-1250-cm(-1) region has been derived from ATMOS (atmospheric trace molecule spectroscopy) high-spectral-resolution IR transmission measurements. Using models of aerosol and cloud extinction, we have performed weighted nonlinear least-squares fitting to determine the aerosol-volume columns and vertical profiles of stratospheric sulfate aeroso...
