On the other hand, the reduction of the elliptic ratio weakens the asymmetry of the flow for regimes D and F.
The validation was carried out with the experimental data provided by Dutsch et al. [17] (DDBL98).
This decreases with the reduction of the elliptic ratio.
The reduction mentioned above is related to a reduced asymmetry of the flow field, caused by the arrangement effect.
This code has been validated by the available experimental data.

A comparison between the calculated and experimental data has shown their good correspondence.
Kuz’menko, Determination of the temperature range of melting of the welding fluxes on the basis of the data obtained in thermal-electric analysis, Avtomat.
Results of modelling and comparison with experimental data The equations of the model were solved numerically for the experimental parameters.
The obtained calculated data on efficiency of drops and a flux well compares to recently published data of Prof.
These data well correspond to experimental data.

Strength reduction factors and stiffness reduction factors of the wall with opening provided by JASSS are based on elastic theory or simplified equilibrium equation, which are not suitable for the conceptual design of ultimate strength.
Therefore, a seismic design method for shear wall with opening based on ultimate capacity is proposed, and the experimental data of 35 walls coming from seven literatures are compared and analyzed.
The results indicate that the data and suggested formula for calculating shear strength are in good agreement, and the formula can be used for structural design.
A reduction factor was applied to calculate ultimate lateral bearing capacity and shear stiffness.

The Effect of Doping Ce and Fe on the Mn/TiO2 Catalyst for Low Temperature NO Selective Catalytic Reduction with NH3 Shiye Fenga , Pan Gaob, Changqing Dong*c, Qiang Lud National Engineering Laboratory for Biomass Generation Equipment, North China Electric Power University, Beijing 102206, China afsy0716@163.com, bgaopanncepu@gmail.com , ccqdong1@163.com, dqianglu@mail.ustc.edu.cn Keywords: NO conversion, Doping, Mn/TiO2, Ce-Mn/TiO2, Fe-Mn/TiO2.
A series of manganese-cerium oxide support titanium oxide with different Fe/Ti, Ce/Ti ratio were investigated for selectivity catalytic reduction of NO low at temperature with NH3 as a reducing agent.
It is a previous technology for selective catalytic reduction of NO with NH3,also is effective technology for stationary sources.
Each data was recorded every 15 minutes after the temperature was maintained in setting value.

Such data are needed to formulate precise constitutive equations for strain rate sensitive materials.
Based on an investigation of experimental data, strain rate sensitivities of flow stresses of these materials were clarified for the wide strain- rate range.

These finding elucidated the effectiveness of changing of fuel quality to the reduction of airborne air toxic concentration in Bangkok environment.
Data collection The air monitoring data used in this study were from January 2008 to December 2012.
Data Analysis Daily average (24 hours average) of Benzene and 1, 3-butadiene data were used in this study.
Zero value was used to replace non-available data.
As for the cases that data values were less than mark (<), half of those values were used in the analysis. 3.

Data Collection At this stage, data were collected through company observations, focusing on production activities and production times.
This time data was later used for value stream mapping.
To ensure the accuracy of the production time data, rigorous testing was performed, including data adequacy and uniformity tests.
The following table tabulates lead time and inventory calculations based on the data obtained.
Below is detailed rejection rate percentage data for misprints.

Fig.2.Curve of safety factor changing with rainfall When no reduction, safety factor: S0=1.88 > 1, the slope is safe and it doesn't cause the landslide.
When S1=1.24>1, the safety factor reduces by 34.04% compared with no reduction.
When S2=1.06 ≈ 1,the safety factor reduces by 43.62% compared with no reduction, it would cause the landslide if the rainfall has a slight increase.
When S3=0.95 <1, the safety factor reduces by 49.47% compared with no reduction, the safety margin is 0.
Fig.3.Running interface of the new control of ArcGIS GIS is an effective tool to solve the special requirements of mass data's support, storage and analysis in the research of landslide, and it provides powerful support for the extraction of spatial data and the show of landslide prediction[5].

An effect of the openings placed close to a column on the punching capacity was taken into account by the reduction of the control perimeter length according to Fig.2 and concentration of the shear stresses at the shorter edges of a column by the further reduction that is shown in Fig.2.
The results obtained vary with different consideration of the reduction of the control perimeter lengths in accordance with Fig.2.
The first evaluation is with reduction of control perimeter length due to elongated column, where cmax > 3d and the second is without this reduction.
The same reduction of control perimeter length due to the presence of the openings (Fig.2) was considered in both cases.
