The objective of this work was to observe and quantify the onset and evolution of localised deformation processes in sand with grain-scale resolution. The key element of the proposed approach is combining state-of-the-art X-ray micro tomography imaging with three-dimensional volumetric digital image correlation techniques. This allows not only the grain-scale details of a deforming sand specimen t
We present some general estimates of the scattered electromagnetic fields for a general bounded scattering domain in the anisotropic materials setting. In particular, it is shown that the L2-norm and sup-norm of the scattered field in an arbitrary finite exterior domain are bounded by the Hcurl norm of the incident field. Moreover, several estimates of the traces of the scattered field on the boun
In this work, physical and chemical characterization of El- Lajjoun retort water from oil shale pyrolysis process has been carried out. Comparison of different treatment methods for the major components which could affect the design and operation of any set of wastewater treatment process were conducted. The removal of phenol and ammonia using activated carbon after 12 hour resident time were 93 a

The relationship between a physiological index called the photochemical reflectance index (PRI) and photosynthetic light-use-efficiency (LUE) of a Siberian boreal forest during the winter–spring transition, or green-up period, was investigated in 2000. During this time the photosynthetic apparatus was considered under stress as a result of extremes of temperature (from −20 to 35 °C) coupled with a

The aim of this paper is to highlight and discuss the complexities of scholarly publishing being a practice closely relating to two different systems, the system of academic merit and the system of scholarly communication, by showing how the two systems work on different sets of logic and therefore needs to be analyzed in different ways and using different kinds of data. These complexities are dis
This paper analyzes and solves an integral and its indefinite Fourier transform of importance in multiple scattering problems of randomly distributed scatterers. The integrand contains a radiating spherical wave, and the two-dimensional domain of integration excludes a circular region of varying size. A solution of the integral in terms of radiating spherical waves is demonstrated. The method em
