Unsteady seepage theory As for the homogeneous isotropic material, the differential equation for one-dimensional unsteady seepage is presented as follows[6]: (1) Where is the permeability coefficient; is the unit storage amount, namely the released water in saturated soil of unit volume by soil compression and water expansion when unit water head drops.

On the other hand, plate efficiency of extraction column is low because the crude material contains complex components and much suspended matter, especially when there is a lot of precipitate after a period of continuous operation.

Introduction Surface roughness is a very important characteristic of any material and in the case of a coated paper is a critical feature.
Materials and methods Two precipitated calcium carbonates were used: CC-S, of calcitic nature, with scalenohedral particles shape, and CC-A, of aragonitic nature with acicular particles.

The parameter C represents an energy penalty for slip confined to one plane; i.e., materials that have a tendency to twin might be expected to have a large, positive value of C.

There are lots of evidences in the literatures [1-9] indicating that grain boundary plays important roles in the mechanical behavior of polycrystalline materials.
This work will help us to understand deeply the damage and fracture mechanisms and their processing of the polycrystalline materials. 2.
For polycrystalline materials, lots of grain boundaries exist in material, so it is difficult to predict the stress distribution near the grain boundary.
In order to discuss the mechanism of material, it is concluded that homogenous assumption for polycrystalline materials is not suitable to study the meso mechanisms of the damage and fracture and their detail processing.

This shows how traditional spatial strategies can be strengthened by innovative materials.
Materials remain ~60% traditional (earth, wood, tile) and ~40% modern (e.g.
At end-of-life, ~80% of materials are recyclable or biodegradable, unlike petrochemical-heavy contemporary constructions.
Use of regionally sourced, low-carbon materials leads to ~45% lower embodied energy relative to new NZEB construction.
