Abstract: Using finite element software, Plaxis model and the measured data, the finite element analysis for the shallow tunnel of crossing the street tunnel in saturated soft clay shallow driven method, studied the influence of crossing the street tunnel and the change of stress field of the strata for the soil around different parameters (tunnel wall stiffness, construction load, soil disturbance).
Combined with practical engineering in Wenzhou, using Plaxis finite element software, the model and measured data, the detailed analysis about the influence of the pedestrian subway level channel as well as the formation stress field change for different parameters (lateral brace rigidity, stiffness of diaphragm wall, soil disturbance) of the surrounding soil.
Fig. 4 ( a ) demonstrates the comparison of surface vertical settlement under tunnel center line with different bending stiffness of tunnel construction, the results show a greater stiffness reduction.

The five phases-Sensor
attachment, Data transmission, Data acquisition unit, Back end data processing, and Evaluation -
represent a dynamic, flexible guideline for building effective human motion analysis and movement
performance detection support tools [2, 3].
Then, scatter plot was produced from data to dig up more information.
Then the data was post-processing for noise reduction before spectrogram was built.
This data would be working in parallel with accelerometer.
All data are process under the same platform without bias.

This is consistent with the experimental data of Modigell and Koke [5] where one observes a vertical shift of the flow curve with rest time (i.e. increase structure) and hence no significant change in the material constants.
For closure, the evolution of the structural parameter is assumed to follow the first-order rate evolution equation: where Dλ/Dt is the material derivative, a is the recovery parameter, and b and c are the breakdown parameters determined from experimental data.
The squeeze rate appears not to be affected initially by a, but as the experiment proceeds, the flow decelerates at higher values of a with significant reduction on the final height of the compressed sample.
The results for confirm that by increasing b the material bonds are forced to break-up faster with significant reduction of the mean structural parameter.
These differences and the complexity of the resulting flow field show clearly that the only way to extract reliable data is by using computational rheology: the actual experiment must be simulated with high accuracy and by using reverse engineering extract the actual constants Conclusions The simulations show clearly that the results from the squeeze flow experiment can vary and they depend on whether the sample is squeezed under constant force or under constant velocity.

Electrolytic reduction is used for industrial production of the alkali metals.
The options for new processing techniques are limited because sodium has a strong affinity to both oxygen and water and thus cannot be electrolyzed in aqueous solutions due to its negative reduction potential.
The acquired chromatographic data were analyzed and the concentrations of NaCl were recorded. .
The electrochemistry was performed using 263A potentiostat/galvanostat (EG&G, USA) controlled by computer and data acquisition software.
Data listed in Tables 2 and 3 shows the effect of the parent cation, i.e. head group, on the solubility of NaCl.

Characterizations: Mo recess was measured by the width reduction of metallic NWs from the TEM images acquired using a JEOL 2010F TEM (JEOL Ltd., Tokyo, Japan) operated at 200 kV equipped with a OneView camera (Gatan, Inc., Pleasanton, CA, USA).
This data suggests that the thickness of the oxide layer slowly saturates over time, rendering the oxidation self-limiting.
E) The plot of average Mo recess per cycle (based on two cycles of etching data) as a function of the varied oxidation time while keeping the same dissolution treatment.
The linear fitting data suggests the Mo width reduction rate is ~2.3 nm per cycle, corresponding to Mo recess from each side is ~1.1 nm under this oxidation condition.

In a recent publication [1], we presented our preliminary data for one AA1050 sample cold-rolled to a von Mises strain of 6.4.
Similar to recent observations by Quadir et al. [6] and Zahid et al. [7], the coarsening was accompanied by a reduction in the fraction of HABs (see Table 1).
The reduction was however not significant in the centre layer considered in the present work.
This description is well supported by the data in Fig.4.
Godfrey for useful discussions and to S. van Boxel for plotting the ODFs from the EBSD data.

As shown in Figure 1, flow alteration in the representative hydrological site of RURYR was characterized by analyzing daily flow data from Zhutuo hydrological station, which is in the main stream of the lower reaches of RURYR.
The data of flow series (1960-2010) from Zhutuo hydrological station was collected and used, but the data from 1968-1970 was missing.
The results can reach the same conclusion with Figure 3, except that the degree of reduction in December gets smaller during these periods, therefore, the slope is negative but very small.
In these 50 years, it seems no big reduction as a whole, but varies differently among flood and dry months.

The peaks corresponding to (100), (002), (101), (102), (110), (103), (200), (112) and (201) diffraction planes were detected in the spectra which in accordance with international centre for diffraction data (79-0206) and no impurities peaks were detected.
Chemical composition of synthesized ZNPs was examined, and EDS data confirmed that synthesized products were ZnO.
These data implied that ZNPs exhibited a high degree crystallinity with a pure hexagonal wurtzite structure.
The reduction of sensor resistance under humid ambient could be explained as the following.
Finally, H+ ions can move freely in chemisorbed and physisorbed layers which acted as a dominated carrier via proton-hopping mechanism, resulting in a reduction of sensor resistance with the increasing of RH value [5].

Glycerol-3-Phosphate Dehydrogenase (GPDH) Activity - The GPDH assay was performed
by a spectrophotometric method for determination of the disappearance of NADH during GPDHcatalyzed
reduction of dihydroxyacetone phosphate under zero-order condition as modified by Wise

Results Reduction of differentiation in cultured 3T3-L1 preadipocyte by t-CLA.
The results showed that, similar to the results of TG contents, Oil Red O of the cells adhered on the collagen-coated surface in the presence of 75 µM t-CLA was higher than that on the PS surface possibly because collagen-coating increased the lipid accumulation and reduced the induction of apoptosis in 3T3-L1 preadipocyte (data not shown).
Our data, together with these results, suggest that collagen coating provides stabilization in adipocyte differentiation and also collagen-coated surface is more suitable than PS surface for adipocyte development study in the presence of t-CLA.
