Cohesion affects the microstructural mechanisms of momentum transport in granular flows, yielding a phase diagram that unifies several flowing regimes.

Estimating active earth pressure accurately is very important when designing retaining wall. Based on the unified strength theory and plane strain assumption, an analytical solution has been developed to determine the active lateral earth pressure distribution on a retaining structure with the inclined cohesive backfill considering the effect of the intermediate principal stress. The solution d...

We report results from a statistical analysis of avalanches of cohesive powders in a slowly rotated drum. Interparticle adhesion, which diminishes the effect of inertia and whose magnitude strongly fluctuates in a local scale, makes avalanches in slightly cohesive powders eligible for displaying self-organized criticality. However, the results show that avalanche sizes, time interval between av...

limited number of mutually specific cohesive sites implied thereby suggests a specialized biological function, one that remains to be identified. Summary.-The DNA of phage lambda undergoes reversible transitions from linear to characteristically folded molecules, and from linear monomers to open polymers. Some conditions favoring one state or another have been defined. It may be surmised that e...

This paper investigates factors that can be used in discourse analysis, specifically, cohesive devices. The paper shows that cohesive devices such as cue phrases can provide information about the linkages inside a text. We propose three types of cue phrases (the ordinary cue phrases, noun-phrase cues, and verb-phrase cues). An algorithm to compute rhetorical relations between two elementary dis...

Abstract This study focused mainly on the shifts of the grammatical cohesion in texts translated from English into Persian. It aimed to identify the grammatical cohesive devices (GCDs) in ST and TT separately, based on Halliday and Hassn's Model (1976), determine the number of occurrences of GCDs in two texts and finally, illustrate types of shifts of grammatical cohesion and strategies used in...

During consolidation process of saturated cohesive soil the soil stiffness increases. Increase of the effective stress due to dissipation of excess pore pressure causes additional stiffness of soil mass. This phenomenon has a very important effect on the behavior of saturated cohesive soils during dynamic loading. In the current investigation the changes in maximum shear modulus. Gmax and dampi...

The size effect in the failure of a hybrid adhesive joint of a metal with a fiber-polymer composite, which has been experimentally demonstrated and analytically formulated in preceding two papers, is here investigated numerically. Cohesive finite elements with a mixed-mode fracture criterion are adopted to model the adhesive layer in the metal-composite interface. A linear tractionseparation so...

A corpus of reflective tutorial dialogs was tagged for cohesive relationships between student and tutor. We describe our tagging scheme, and show that certain cohesive features of tutoring dialog are correlated with learning in our corpus. In particular, our semantic cohesive relationship tags are significant predictors of learning, while our lexical tag is not. We find that “abstractive” dialo...
