in this study, the development of structural elements and the relationship between these elements and dikes emplacements investigated by the field surveys and analysis of satellite images of the east dasht-e bayaz fault zone. in this area nnw-sse (t2) and nw-se trending dikes are which follow the fractures of the region. we measured geometric characters of dikes (such as thickness, attitude, di...

Anomalously low values of friction observed in layers of submicron particles deformed in simple shear at high slip velocities are explained as the consequence of a one nanometer thick layer of water adsorbed on the particles. The observed transition from normal friction with an apparent coefficient near l = 0.6 at low slip speeds to a coefficient near l = 0.3 at higher slip speeds is attributed...

We developed a 3D-printing process based on thermoset biocomposites termed Delayed Extrusion of Cold Masterbatch (DECMA). DECMA is processing method, controlling the degree curing, that takes some responsibility 3D printing from materials and as such can be used to print otherwise unprintable materials. First, masterbatch was produced by mixing bio-based resin (bioepoxy) sawdust lignin. This pa...

LDPE remains the classic material of choice for many Extrusion Coating Applications, due to excellent processing and end-use performance reasons. High shear extrusion screws are desirable, actually promoting oxidation of the melt for improved adhesion to substrates. T-shaped flat die technology, with internal deckling, has emerged as the premium technology to handle monolayer and multilayer ext...

The flow of glaciers and polar ice sheets is controlled by the highly anisotropic rheology of ice crystals that have hexagonal symmetry (ice lh). To improve our knowledge of ice sheet dynamics, it is necessary to understand how dynamic recrystallization (DRX) controls ice microstructures and rheology at different boundary conditions that range from pure shear flattening at the top to simple she...

Among the multiplicity of construction methods based on digital concrete technologies, most common one remains extrusion-based process. Two opposed strategies have been developed in order to print a structure using extrusion: first emphasizes ease-of-pumping material which is massively accelerated ensure stability structure, when leaving extruder; second uses firm mortar able sustain own weight...
