With the ninth super typhoon storm Muifa large number of infiltration slope body, FEDCB, upper slide zone soil water seepage recharge saturation, slope body soon in full water state, and the original slope FGHI flowing water and mud.
The slope of rock and soil layer is grain filling, silt clay, weathering slate.

The shape of 2# test hole is rectangle, section size is 5m 5 m, its about 12m from the hole to auxiliary hole, the thickness of overlying strata is about 1850m, litho logy is middle and coarse grain marble, Epitaxial compressive strength is 80~110Mpa, elastic modulus is 30~50Gpa. 1.3 Monitoring device Use acoustic emission monitoring system (produces in American PAC Company) which includes: sensors, the preamplifier, acoustic emission acquisition card, host system and processing software to acquisition the acoustic emission signal of this experiment, the acquisition system and working principle of this system.
From the figure and the table 1, We can see: the whole monitoring on November 14 during7:00 to 9:00 in the morning the acoustic emission events is numerous and have a wave, but from 9:00am to 13pm acoustic emission events is reduce and stability, acoustic emission events increase again and have no fluctuations after 13pm,all in all the number of acoustic emission events is stability in the whole process of monitoring; Acoustic emission events and its energy parameters decline because the produce of fissure so the produce of fissure is the result of acoustic emission events frequent activity, and its also a process of energy release; Acoustic emission events is reduce its energy parameters is decline and both of them are keep relatively stable after the produce of fissure ,so this phase can be considered as a stage of fissure development stability.

Therefore, an increasing number of silicon- containing materials are being studied for applications in biomedical materials and devices.
Experimental procedure Commercially available silicon powders having a grain size of 10-50 µm and purity of 99.0% were used as the feedstock.

Obviously, using small sets of coarse-grain abstractions rather than attempting to model the whole domain in detail simplifies management and maintenance in light of continuously evolving environments.
Pervasive Healthcare System Prototype Architecture With the increasing number of the aging populations across the world, we now face the intractable challenge of providing a better healthcare support for the elderly.

As a result of the research made on a large number of steels and alloys, the authors mentioned came to the conclusion that immediately after casting, liquid metals constituted essentially a non-homogeneous unbalanced system.
The melt casting at temperatures lower than 1550 оС ( the low-temperature melt state) contributes to the formation of the ribbon’s rough free-side surface; it looks like being sprinkled with crushed grains (Fig. 3, a).

This technique has a better advantage over normal potentiostatic electrodeposition in terms of its ability to produce samples with a better morphology, crack free, uniform and finely grain size as well as better porosity and well adherent [6].
As the crystalline size becomes smaller, the number of sample per unit area is higher and therefore under illumination, more electron hole pairs can be produced per unit area for the redox reaction at electrode electrolyte interface [12].

Adjustable and the ratio is each kind of aesthetic to the show to two different contradiction movement state grain structure at.
For example, the word of modification, the left and the right should be out of the empty white certain in a page, the word line number is generally not exceed 10 lines, each line in the 25 character in the title character, generally in 40 or 44, it shall not be less than the 20 or more than 32.

(see Fig.6) Fig.6 Construction project information management mode based on BIM technology The information database formed through computer n-dimensional model by BIM is a large number of important information data building in the life cycle of construction building.
Better communication and collaboration has been achieved through data mutual use of project cost between different project participants, which greatly facilitates the management and supervision on project decision-making and quality management by the main responsibility supervision and administration department, solves the bottleneck problem of the construction informatization or project cost, promotes the building life cycle management, realizes the integrated cost management of the various stages, promotes the fine-grained and intensive cost management of construction projects.

In addition to semi-coke the chemical products of pyrolysis (resin and gas) and sulfur compounds (pyrite crystals and pyrrhotite grains) with pronounced ferromagnetic properties and therefore easily extracted by magnetic separation are also obtained [6, 1].

When ions of Cu doped into CeO2 lattice, it locates in grain boundary to inhibit the growth of CeO2 crystals.
Since the radii of Cu+/Cu2+ and Ce4+for coordination number 6 are 0.091, 0.087 and 0.101 nm, respectively [13], it is easy for copper ions to cooperate with the matrix of the CeO2 particles without causing a significant crystalline distortion.
