The data is presented as mean and standard deviation (SD) calculated over three data points at least.
Results and discussion Au-Au2S NPs were obtained by reduction of tetrachloroauric acid (HAuCl4) using sodium sulfide (Na2S) [2].
Combination the earlier data of MTT assay, two-stage cell transformation assay in vitro, hemolysis assay, pathological examine [5-7], it is thus suggested that those NIR sensitive nanoparticles are non-toxic below the maximum recommended dosage.
Considering the earlier reported data [1, 5-7], it is possible to employ NIR sensitive cisplatin-loaded Au-Au2S NPs for cancer therapy in the future.

BIM helps the whole project to achieve the goal of energy saving, cost savings, pollution risk reduction, which meets the need of a green construction project.
The project data which formed in design and construction stage can be easily used into facility usage phase.
So the test data can be made full use by the building space management, operations management, property management and maintenance planning.
The BIM is not only the 3D data model building, but also to achieve the synchronization of construction, structure and appliances information.
BIM links project planning, design, construction operation and other aspects together to achieve information data modeling.

A least square fit to the data in Fig. 1b indicated that the net donor concentration, Nd of the 3C-SiC film was 8.3 (± 0.3) × 10 16 cm-3, which gives an excellent fit to the measured data in Fig. 1a.
We modelled the experimental data in terms of the theoretical work of Nicollian and Goetzberger [5], and we used the statistical model for the equivalent parallel conductance Gp from which the interface state density (Dit) can be extracted.
A theoretical fit to the experimental data results in the determination of Rs, σn, Dit and σs.
There appears a correlation between the decrease in the Dit and reduction of σn near the band edge, but further works are necessary in order to understand this phenomenon.

Three different samples of each composition were sintered and the results listed in this article are the average data obtained for these samples.
Data on composition and compressive strength of the samples are listed in Table 1.
Figure 1- SEM image of diamond-Si composite Data on hardness and fracture toughness are listed in Table2.
This reduction in mobility thus leads to an increase in the fracture toughness of the diamond-SiC nanocomposites.
According to the literature data, better hardness results are obtained for pressures above 7GPa.

The advantages of modern manufacturing process have confirmed the need for automated system over the traditional way of manufacturing in terms of cost reduction, mass production, improved quality, increased competitive advantage, better management control and increased flexibility [1].
The common procedure of machining for TCM was employed for the acquisition of data during the different machining phases.
Pre-processed signals were channeled to the BNC board and to the National Instrument’s (NI) data card for further processing and storage.
The interfacing is done by using LabVIEW graphical data logging software.
Each machining test pass was conducted along the length of the workpiece and the AE data of each pass was recorded (Fig. 1).

In this paper, according to the data of Tangshan Binhai Avenue sandbag cofferdam’s landslide accident, we integrate stability checking calculation using method of limit equilibrium, analysis and adjustment of parameters, comparing with finite element numerical simulation and other means, in order to analyze this nearly horizontal plane landslide, summarize its genesis, deformation mechanism, and provide prevention basis for this kind of landslide.
Using the data got from soil experiment and displacement of embankment monitored on -site, we make back analysis of the soil’s mechanical parameters, main soil layer distribution and physical properties of this section are shown in Table 1.
Although this data has certain deviation with the actual result, it could explain the phenomenon that the cofferdam has been damaged and validate the results from limit equilibrium method.
Because the construction rate is rapid, the pore water is not easy to dissipate from foundation soil in low permeability layers, so the appropriate reduction of c, is needed to reducing the value of shear strength of soil and get results closer to the actual data.

From statistical data, the growth rate of convenient stores in Thailand is rapidly increasing [1].
The results from previous study [2] showed that the improvement of store’s envelopes can achieved the reduction of cooling load of the stores up to 10% only.
Table 1 shows the basic data regarding the construction of the store.
Basic information of the convenience store for this study Floor area in sales area / non-sales area 138 m2 / 50 m2 Ceiling height 2.64 m Store’s orientation North Sales area’s envelope materials Clear glass, 10 mm thick Non-sales area’s envelope materials Concrete wall, 100mm thick Roof’s material Metal sheet, 0.5mm thick & PE insulation, 10mm thick Methodology The analysis of the micro co-generation system comparing it to the conventional system was executed based on end-used demand data of hourly electricity energy consumption as illustrated in Fig. 3.
Data assumption for the analysis Fig.4: PES values with various micro-CHP capacities In this study, a micro co-generation system driven by natural gas is considered, combined with the utility electricity and air conditioning system in order to accommodate the energy demands.

Results and discussion Fig.1 shows the XRD data of the high and low purity silicon kerf.
XRD data confirms that the crystalline phases of two samples are different.
Particle size analysis data of high purity silicon kerf in Fig.5 shows uniform particle size distribution.
Conventional carbothermal reduction of SiO2 for the synthesis of SiC powders involves many steps and is an energy-intensive process [7].

Indeed, the grain size reduction is one of the main factors enhancing the sensing properties in case of nanocomposites.
The X-ray diffractogram (Fig.2a) of Ag-Pani nanocomposite exhibits a broad and intense peak in the range of 10-25o which can be attributed to polyaniline [7] whereas the sharp peaks at 2θ values of 37.67 0, 44.310 and 64.12 0 correspond to the silver metal which are in well agreement with the A.S.T.M. data.
The FT-IR spectral data of exposed and unexposed Ag-Pani nanocomposite is given in table 1.
Table1: FT-IR spectral data of Ag-Pani nanocomposite before and after exposure to ammonia vapors.
The FTIR spectral data of exposed samples when compared with that of the unexposed one, revealed notable changes in the quinoid and benzenoid band positions.The band corresponding to the benzenoid structure (~1486 cm-1) is found to shift towards lower energy with increased intensity and sharpness in ammonia environment.
