Coir pith is a light, fluffy material which is the fiber from the coconut husk.
Materials and Experimental Procedures Chemicals Zinc nitrate (Zn(NO3)2.4H2O) and lead nitrate (Pb(NO3)2.4H2O) were purchased from Asia Pacific Specialty Chemicals Ltd.
The results showed that modified coir pith is a potentially useful material for the removal of Zn(II) and Pb(II) ions from aqueous solutions.

Experimental material.
Therefore, in order to prove that 0.382 is the optimum value of SWC (fine)/ SWC (coarse) ratio in real materials, more accurate facilities, more powerful analytical software and more meticulous experiments are required.

However, when using the explicit solver in the procedure, the beam element is lack of concrete material model which could be applied to 3-D analysis effectively, the author established an applicable Scott-Kent-Park concrete material model subroutine through secondary development [7], and made some comparative analysis on columns and shear walls under low cyclic test and frame-shear wall structure shaking table test, which has verified the validity of the secondary developed material subroutine.

Third, changes in family composition and lifestyle promote changes in the use of space, construction techniques, and materials for traditional architecture, resulting in the loss of the original characteristics of traditional settlements.
In terms of preserving the Dong rural settlement, it is as serious as the changes in building materials and structure techniques.
However, changes in modern lifestyle have transformed the original homogeneous settlement continuum into hetero-buildings that feature different materials, construction techniques, and architectural forms (Fig. 9).

Both structures are made of electrically conductive materials, and are separated by a dielectric medium (see Fig. 1).
The electric field and charge dominate neglecting the magnetic effects at higher frequencies, and the polarization effects become important in materials with slight conductivity.
