Heavy vehicle cooling fan is seen as one of the main means of vehicular fuel efficiency reduction.
Therefore, in this research, the performance data of motor is to make use of measured data of Dynamo.
Motor efficiency in equation 1 is obtained from the measurement of motor performance data.
When we apply algorithm for taking account of CFD analysis and test data of motor, starting from random rotating speed, torque of motor testing data and torque of CFD analysis will converge to the same value following enough time of calculation.
Figure 8 demonstrate graphs for linking CFD of axial flow fan with testing data of motors.

Kinetics and substrates optimization on a facultative and methanotrophic bacterium ZHAO Tiantao1,a, ZHANG Lijie1,b, ZHANG Yunru1, PENG Xuya2 1College of Chemistry and Chemical Engineering, Chongqing University of Technology, Chongqing 400050, China 2College of Urban Construction and Environmental Engineering, Chongqing University, Chongqing 400045, China aE-mail: tiantaozhao@gmail.com, bE-mail: zhljtt@cqut.edu.cn Keywords: Methane reduction.
Facultative methanotrophs reported recently could only utilize a few of C2, C3 and C4 compounds, which limited the application of methane oxidation in the engineering of greenhouse gas reduction due to the difficulty of cells propagation.
These data would suggest that methane is the more preferred substrate for M. sp.
Metabolic and biochemical characteristics of the strain open up a new possibilities for environmental biotechnology, such as some potential applications in methane reduction emitted from soil or landfills.

On the basis of similarity conditions, laboratory model parameters were determined so that data acquired for the model may be referred to real-world structure.
Steel slender structures usually have small internal damping ratios and that is why they are frequently equipped with vibration reduction systems.
It is very important if model to be built will serve as a basis for synthesis of active or semiactive vibration reduction control system.
Considering the fact that the model will be used for study of vibration reduction system placed at tower’s tip, the proposed solution will be satisfactory.

For example, based on the panel data posed by 22 OECD countries, Inmaculade Martinezarzoso[10] found that there is N-shaped relationship between GDP and carbon dioxide emissions.
Empirical Analysis Data Sources This study selected industrial GDP as an indicator to reflect the industrial economy, with per capita industrial wastewater, waste gas and solid waste emissions as the three indicators of reflecting the degree of environmental degradation.
In this study, the timing dimension of data analysis is 1990-2010, and data sources are obtained by Organizing and calculating data from China Statistical Yearbook and Sichuan Statistical Yearbook each year in Table 1.
If the sequence has a non-stationary line, it must be obtained stationary data after difference in order to further conduct cointegration test and impulse response analysis.

Step 3: In the third step, the data normalization takes place according to the Equation 2.
Initially, all the data is gathered to develop a parameters vector, known as particle as per the PSO viewpoint.
Therefore, normalization of the data became mandatory to carry out further analysis.
In the second step, normalization of the data was done using VIKOR method.
In this step, first the data was converted into matrix form using Eq. (1).

NiO nanoparticles had a similar effect on membrane integrity as that observed for inhibition of cellular metabolic activity, with a significant reduction in membrane integrity.
All data were presented as means±standard deviations and were tested for statistical significance using analysis of variance processed by statistical package Origin (version 7.5).
Data were tested at significant levels of P< 0.05 using one way ANOVA.
No significant (P>0.05) difference compared to the control could be detected for the other exposure concentrations, but viability reduction was 80% at 25.0mg/L for NiO nanoparticles.
A larger reduction in viability was observed for membrane integrity than for mitochondrial activity at all exposure concentrations.

A Method of Load Prediction in District-heating System based on Data Mining Lanbin Liu*, a, Aijuan Zou and Yufei Ma 1 School of Mechanical Engineering, University of Science and Technology Beijing, PR China aliulanbin@ustb.edu.cn Keywords: Load prediction, District-heating system, Data mining.
This paper provides a load prediction method based on data mining and considered the physical mechanism of heating load formation.
In order to further identify the characteristics of systemic energy the hourly energy consumption of the building is used for further analysis and data mining.
Therefore during the data mining process, the moving weighted average method is used to give different weight value to indoor and outdoor temperature differences of each time to identify the system.
In order to eliminate the effects of solar radiation and ventilation, the simulation data at night time (20:00 - 4:00) is used only.

Summary of Background Data Kyphoplasty (KP) involves placement of inflatable bone tamp via unilateral and bilateral approaches.
Results Both unilateral and bilateral kyphoplasty resulted in significant pain reduction.
After reduction of the fracture bone, cement is deposited into the cavity created by the IBT to repair the fracture.
The two groups of KP resulted in marked and sustained pain reduction.
Chung et al[8] compared the outcomes of unilateral and bilateral KP and found out that bilateral group had a greater advantage in the reduction of kyphosis and the loss of reduction was less than the unilateral group.
