Cohesion as an indispensable linguistic feature in discourse analysis and translation has aroused many researchers' interest. To explore the regularity in shifting cohesive devices from English into Chinese our study was designed to analyze the similarities and differences of cohesive devices between English medical texts (EMTs) and their Chinese translation texts (CTTs). A parallel corpus cons...

At the ends of bacteriophage P2 DNA, the S’-terminated strands are 19 nucleotides longer than the 3’-terminated strands. The complete nucleotide sequence of the two cohesive ends of P2 DNA has been determined. This was accomplished by repair synthesis, using Escherichia coIi DNA polymerase and labeled deoxyribonucleoside triphosphates with or without a ribonucleoside triphosphate, followed by p...

We consider the minimum permanents and minimising matrices on the faces of the polytope of doubly stochastic matrices whose nonzero entries coincide with those of, respectively, Um,n = [ In Jn,m Jm,n 0m ] and Vm,n = [ In Jn,m Jm,n Jm,m ] . We conjecture that Vm,n is cohesive but not barycentric for 1 < n < m + √ m and that it is not cohesive for n > m + √ m. We prove that it is cohesive for 1 <...

Rapid prototyping (RP) is an emerging technology which is having a significant impact on product development cycle time and management. This technology enables the making of objects directly from computer models within the time and cost parameters needed by engineers to develop new products and prepare them for manufacture in quantities. RP is a multidisciplinary as well as fast evolving techno...

Of interest in this paper are failure mode interactions when laminated fiber reinforced composites are subjected to compressive loading. Delamination, fiber kink-banding and their interactions are seen to dominate the failure response. This interaction is captured through a computational model that includes interface elements to capture delamination, and, geometric and material nonlinearity to ...

Two-dimensional meso-scale finite element models with real aggregates are developed using images obtained by digital image processing to simulate crack propagation processes in concrete under uniaxial compression loading. The model is regarded as a three-phase composite material composed of aggregate, mortar matrix and interface transition zone (ITZ). Cohesive elements traction–separation laws ...

We present a model for fluid-saturated granular media coupled flow and mechanical deformation. The fluid is assumed to be incompressible and the solid part is assumed to be a cohesive granular material. Forces exerted by the fluid in motion are determinated and applied to solid particles. We derive a finite volumes formulation of the flow problem and we couple it to a discrete element method (D...

We present numerical simulations of the fall of a two dimensional (2D) model granular material in a rectangular container and study the decompactionof this granular assembly consisting of non-cohesive particles. During the fall we observe the occurrence of cracks splitting the initial pile into pieces. Cracks preferentially occur in the lower part of the array, an eeect also observed experiment...
