It was obvious that the CS-TCP composites became denser with the increase of sintering temperature and the grain growth was also observed when the sintering temperature increased.
After culturing for 7 days, the cell numbers increased considerably compared to those at 3 days.

Weibull's statistical test was performed according to ASTM S 1161 procedure at the loading speed 0.5 mm/min using an estimator Pi = i/(N + 1), where P is probability; i is specimen number, and N is specimens set size.
SEM observation revealed a mixed trans- and intergranular mode of crack propagation (Fig. 4), so the grain boundaries could suppose to play a dominant role in the initiation of the fracture crack propagation due to the boundary stress corrosion process.

Moreover, fly ash with very fine grain size filled in porous structure of marble and thus decreased the permeability of composite materials.

On the basis of reading and studying a large number of excellent papers, we present a human motion detection method based on a RGB space technology.
It can not be changed with the different grain and color in the covered background. ③ The boundary of the shadow will change with the variation of the geometrical characteristic in background surface. ④ The shadow is closely related with the object and its behavior.

Carbon particles may suppress the recrystallization of PEO grain when CPE is dried.

We can calculate the density of the nanosheets, based on the number of nanosheets through each horizontal line in each SEM image and take an average.

The NaPO3 and Na3PO4 compounds do not exhibit a significant effect concerning the density increase, because the lack of the liquid phase at the grains boundary.

Introduction Fertilizer application, which is the best way to increase crop yields, plays an important role in national grain safety [1, 2].
Richie put forward the “Crop-environment resources information system”, and a recommended amount of nitrogen in corns and wheat based on a number of climates, crop varieties, physiological characteristics, balance in moisture and nutrients [7, 9].

The thickness of Au layer in traditional eutectic bonding of Si-Si is only 500nm, which is required up to 1.5μm in PZT-Si eutectic bonding, because thick Au layer can guarantee the high flatness of the bonding surface for big grain in bulk PZT, thus guaranteeing the strong bond strength.
