Table 1 shows the results kinematic viscosity and the percentage reduction in viscosity of biodiesels obtained using as catalysts SBA-15 and Al-SBA-15 (Si/Al = 10 and 100).
Sample Kinematic viscosity [mm2/s] reduction in viscosity [%] Soybean oil 34.28 - Biodiesel (SBA-15) 32.45 5.33 Biodiesel (Si/Al=10) 28.68 15.64 Biodiesel (Si/Al=100) 30.67 10.51 Based on the data presented in Table 1, it is found that the viscosity value for the soybean oil was 34.28 mm2/s (40°C).
This value is in agreement with data in the literature [17], 35.00 mm2/s (40°C).
Observing the values found for the viscosities kinematics for SBA-15 catalysts, Al-SBA-15 (Si / Al = 10 and 100) for a time of 4 hours reaction, reduction is found to 5:33, 15.64 and 10:51%, compared with the value of the cinematic viscosity pure soybean oil.
The introduction of aluminum showed an increase in acidity, as shown by FTIR analysis and reduction in the kinematic viscosity.

Experimental and �umerical Methods EBSD data collection techniques were previously described in [13].
Orthorhombic sample symmetry (as in the case of the measured data) was assumed for the ODF calculations [18].
In addition, the β-fibre intensity increased with further rolling (to a total of 74.4% reduction).
Similar results were obtained when the hot band samples were cold rolled, up to 89.4% reduction, without prior annealing.
Intermediate annealing leads to a reduction in spatial banding of Cube grains in the final annealed material.

Profit approximately reflects the bidding units’ the amount of price reduction and sharing profit margin, the amount of price reduction higher than the amount of profits, it means the unit bidding prices below the cost to compete.
There are m evaluation indicators, n evaluation objects, and then formed the original data matrix
The above data showed that, A bidder' environmental risk, process risk ,decision objectives risk, scores were 70.55, 77.1and 79.1, composite scores75.25.
Because under normal circumstances a reasonable profit and the risk of the project in direct proportion, so A tender unit profit is general, the profit approximate reflects the amount of price reduction and interest concessions, which determine A, none other can not be the lowest.
If the lowest, then the A tender ' the amount of price reduction will be higher than the level of profits, it means that the A tender offer will be below cost price to compete.

Introduction Supercavity is a revolutionary technology to drag reduction for underwater vehicles with a high velocity, it can reach a drag reduction at 90%, and the technology brings great influences to developments of underwater vehicle[1].
And the researches by Kirschner et al[4] have verified that the ventilated and natural cavities possessed the same characteristics both in shape and drag reduction.
Numerical Simulation Comparison of Simulational Results with Classical Experimental Data.
Figures 1 and 2 present the experimental and simulational results of cavity length for cone cavitator under different cavitation numbers, the curves indicate fine consistence of experimental data and simulational results, with the reduction of cavitation number, the cavity length and maximum diameter increase.

Nevertheless, the reduction in size and higher rotational velocity of the pump usually means an increase in vibration and noise as well as a reduction of pumping efficiency.
The causes of flow pulsation and its influences As shown in Fig.1,the fundamental working principle of an external gear pump is the volumetric displacement of a space that opens and is consequently filled by fluid; transport of this fluid to another zone in the machine; and reduction of this space, which increases the pressure of the fluid and forces it through the outlet pipe.

Analysis is then done to check the percentage of reduction of response of structure.
Also limitations in using damping ratio as sesmic response reduction measurement were emphasized.
This type of analysis is used to determine the response of structure under the action of El-Centro earthquake data.
