Architecture requires creativity and its teaching is a creative issue and accordingly, teaching architecture is complex and it cannot be limited in determined and pre-defined frameworks. Despite the educational scholars’ efforts in recent decades, and by some reflections from the architectural works in this period, it is observed that such teaching styles are accompanied with failures ...

The analysis of construction curves limiting deformations metals is carried out in the work. It established that traditional test methods, such as deposition and stretching cylindrical specimens, do not ensure constancy stress state, therefore contribute to history deformation curves. During deposition, there an increase state due curvature lateral surface sample (barrel formation), which cause...

Multidentate materials formed by simply mixing heterogeneous and homogeneous components are promising for construction of versatile active sites on the surface of heterogeneous compounds, however, to the best of our knowledge, there are no reports on such materials. Self-assembly of hetero-hybrid catalytic materials occurs when heterogeneous catalysts having adjacent Lewis acid-Lewis base sites...

When cement-based materials are transported at a construction site, they undergo high pressures during the pumping process. The rheological properties of the materials under such high pressures are unknown, and estimating the workability of the materials after pumping is a complex problem. Among various influential factors on the rheology of concrete, this study investigated the effect of miner...
