The present paper offers a meso-scale numerical model to investigate the effects of random distribution of aggregate particles and steel fibers on the elastic modulus of Steel Fiber Reinforced Concrete (SFRC). Meso-scale model distinctively models coarse aggregate, cementitious mortar, and Interfacial Transition Zone (ITZ) between aggregate, mortar, and steel fibers with their respective materi...

The cascade reaction of sterically hindered dipyrromethanes and formaldehyde furnished meso(10)-meso(10') linked corroles--a new type of porphyrinoid--compounds with interesting photophysical properties.

To explore the nonlinear bond behaviour between ribbed bar and concrete, combined with characteristics of concrete meso-structure surface considering frictional resistance mechanical interlocking rebar a meso-scale model is established. Based on good agreement simulation results experimental results, failure mechanism discussed, distribution stress steel are analysed. Furthermore, based meso nu...

After a short discussion on cell interactions in general and inductive interactions in particular, the almost completely epigenetic nature of amphibian development is emphasized. In the symmetrized egg undergoing cleavage a large-scale inductive interaction occurs which leads to the formation of the meso-endoderm. Meso-endoderm formation gives rise to the morphogenic process of gastrulation. In...

Despite the deluge of bioinformatics data, the extraction of information with respect to complex diseases remains an open challenge. The development of efficient tools allowing the re-engineering of functional biological networks will therefore be crucial for the future of the pharmaceutical and biotech industry. In this paper we present a method for efficient re-engineering of meso-scale netwo...

Wind shear, which refers to sudden and sustained changes in the wind direction and speed, could be hazardous to aviation. Windshear is rather difficult to predict due to its transient and sporadic nature. Moreover, the causes of wind shear may be different at different airports. In some places it is caused by microbursts, while in other places wind shear may result from meso-scale weather pheno...
