Furthermore, these results indicate that the reason for attachment of the secondary fluid to the surface is reduction in surface pressure, which leads to the deflection the main flow and obtaining thrust vectoring.
In addition, this figure shows that secondary slot height reduction caused the enhancement of the thrust vector angle.
The results of vector angle that are computed at the nozzle exit show a nonlinear reduction in thrust deflection angle with increasing the slot height.
Furthermore, numerical model and the results of the computational simulation are compared and validated with the experimental data that were previously approved by the first author for co-flow fluidic thrust vectoring technique and show a good agreement.

So the laterite nickel ore reduction process in the MBF will get better.
Heat loss is high because of the much heat to the wall resulting in a less efficient furnace due to the loss of gas reduction capabilities because after passing through the wall, the gas cools rapidly.
With central working furnace operation, the reduction process of oxides, heat transfer and gas flow in MBF will be efficient, so increase the productivity of MBF.

The cast ingot was homogenized at 913K for 86.4ks, cold-rolled by 90% reduction in thickness and cut into sheets with thickness of 2mm, width of 60mm and length of 200mm.
The ST sheets 2mm thick were firstly cold-rolled by 50% reduction in thickness (equivalent strain of 0.8).
Two pieces of the sheets were stacked to be 2mm thick and roll bonded by 50% reduction under the same conditions described above.
The EBSD measurements were carried out using the program TSL-OIM Data Collection in a Philips XL30S FE-SEM with a field emission gun operated at 15kV.

For a given anodic reaction (or oxidation) there is a corresponding cathodic reaction (or reduction).
Increasing the amount of dissolved O2 in the solution by purging it with O2 gave rise to another possible electron-consuming reaction in addition to H2 evolution – that is O2 reduction as expressed in Eq. 2.
EIS data is commonly analyzed by fitting it to an equivalent electrical circuit (EC) model of the interface.
With regards to the effects of dissolved O2 in the solution, the presence of another possible cathodic reaction, that is O2 reduction, may have increased the initial corrosion rate of the alloy but may have promoted earlier formation of more protective or thicker oxide film as indicated by more positive OCP values in solution with high level of dissolved O2.

Optimum adhesive thickness and overlap length can be calculated from these experimental and analytic results for design of adhesive bonded joint, and results can be the base data to design the adhesive structure.
However the reduction of the adhesive thickness to limitation, the strength not increases but reduces on the contrary.

Introduction In recent decades, long-span prestressed concrete continuous bridge and continuous rigid frame bridge have become increasingly popular in china, however, some bridges appeared excessive downwarping (more than 100mm) after several years of operation, which results in not only large increasing of maintenance cost and unaesthetic, but also reduction of the degree of structure security.
Concerning the factors lead to excessive long-term deflection of bridge, most scholars presently focus on the shrinkage and creep of concrete, whereas ignoring the effect of shear stiffness reduction at segmental joints section on long-term deflection of bridges.
Thus, deflection caused by shear stiffness reduction of segmental joist should be considered into the design of bridges.
Based on the experimental data and finite element analysis, the formula calculating the total area of shear-keys is proposed, however it is necessary for the formula (4) or (5) to point out that the effect of prestress contributing to the shear stiffness of joints is not taken into account.

Miniaturized electrochemical capacitors or micro-supercapacitors are expected to be the power sources for miniaturized electronic devices. [6-10]The current preparation methods of micro-supercapacitors include printing, [11-13] electro deposition, [14-17] catalytic reduction, [18, 19] sputtering and so on. [20-23] David Pech prepared a super-capacitor on the plane of silicon by the ink-jet printing method and the specific capacitance is 2.1 mF/ cm2. [24] Sun has used Deep reactive ion etching (DRIE) to fabricate the 3-D microelectrodes and electrodeposited PPy, and the capacitance is 27 mF/cm2. [25] Beidaghi has developed the activated C-MEMS structures for micro-supercapacitor applications and the geometric capacitance of one electrode at the scan rate of 5mV/s is 75.3mF/cm2.[26] Chunlei Wang with his partners has achieved C-MEMS electrode arrays of lithium batteries.
Electrodes prepared by the catalytic reduction method have a high specific capacitance, but the preparation process is complex and requires a high temperature.
The oxidation and reduction peaks indicate Ruthenium intercalation and extraction to and from the 3-D microelectrode arrays.

This strain was selected for further studies based on the best surface tension reduction and emulsification activity.
It showed the best surface tension reduction from 71.2 to 38.0 mN/m as well as an emulsification activity of 50%.
