Abstract.
PPCPs cannot be effectively degraded by conventional treatment or processes, and the contamination of PPCPs in the environment has become a key environmental concern among advanced nations.
Method and Material Samples for 38 administrative districts of Kaohsiung City were collected to analyze the quantity and composition of discarded pharmaceuticals.

Olivine, which is a naturally occurring mineral comprised of (Mg, Fe)2SiO4, is considered to be suitable as bed-material or catalyst support because of its low cost, high attrition resistance and activity in tar destruction [11–13].
Natural olivine was obtained in the granule form from Hubei mineral, China and the calcium aluminate cement (CA) was acquired from Zheng Zhou Dengfeng Smelting Materials CO.

FLAC500 is a two-dimensional explicit finite-difference program for engineering and mechanics computation.
Ten material models, including several describing highly non-linear, irreversible response, are built in FLAC500, and new constitutive models can been added via the FISH programming language.
Most practical engineering problems are strictly three-dimensional, but in some cases, it can be simplified as a two-dimensional problem and problem solution becomes much convenient and time-saving.
(a)axisymmetric thermal analysis geometry (b) Plane thermal-mechanical analysis geometry Fig. 4 Sketch of the model geometry ·Material properties Density and mechanical propeties ( Young´s modulus and Poisson´s ration) needed for this modeling are listed in Table 1.

Abstract.
In the transmission process of high-speed serial signal with GHz, the main issues for signal integrity are loss, reflection, and crosstalk [6].The loss of signal can’t be simulated and the effective way to reduce the signal loss is to use dielectric materials with lower dielectric constant.
The impedance of transmission line is determined by materials used.

Abstract.
Most of the current deck water-proof materials in China are changed from water-proof materials of buildings[4].
It is well known that there are more strict requirements for deck water-proof materials.
When materials on contact surface of deck laid layer are similar particles, its interlaminar shearing strength is mainly from adhesion force c between water-proof tack coat and asphalt mixtures cover, cement concrete deck panel, and friction force σtgφ caused by sliding rubbing between water-proof tack coat with cover, and deck.
