In this paper, we consider a model equation for the Navier--Stokes strain equation. This has same identity enstrophy growth and number of regularity criteria as full Navier-Stokes equation, is also an evolution on constraint space. We prove finite-time blowup which shows that space are not sufficient their own to guarantee global Navier-Stokes. The mechanism self-amplification strain, consisten...

Most of the field problems in geotechnical engineering are in three dimensional state or close to a plane strain condition. Strength and deformation properties of soils in plane strain condition are considerably different from those in an axisymmetric condition. Many researchers have investigated the behaviour of soils under a plane strain condition. However, most of the previous studies have c...

introduction of modern architecture in iran and its popularization in 1950s and after, brought some new concepts in everyday life of iranian women, among which was “kitchen as heart of home-life”. younger members of current generation are grown in these modernized spaces while a bit older ones have experienced houses of traditional style. this study is designed to explore what previous concept ...
