In this paper, an ultra-fine grained AZ31 magnesium alloy sheet with grain size less than 3µm was generated by three-run accumulative roll bonding of as cast alloy at a deformation temperature of 350°C and a reduction of 80% for each pass.
The ARB process, as illustrated in [17], was always carried out at 350 °C and reduction of 80% using a rolling machine equipped with two 300mm in diameter rollers that rotate at 48 rpm.
The tensile flow stress curve was recorded by a digital controlled data acquisition system.

For reduction of 5α-reductase activities, concentration of CT extract at 0.05 mg/mL exhibited highest 5-reductase type-1 inhibition activity on the DU-145 cell line at 89.96% of the control, higher than standard finasteride (31.39%) and dutasteride (38.58%).
Reduction in the expression of transforming growth factor-β1 (TGFβ1) as the signaling molecule that inhibits epithelial cell growth was also reported [3-5].
Data were analyzed by one-way analysis of variance (ANOVA) for differences between treatments followed by the Bonferroni post-hoc test (SPSS, Chicago, IL, USA).

.% ODA unabled to enhance the capacity of CO2 captured due to pore blockage and reduction in SG pore surface, thus hindered the physisorption between CO2 and SG.
This data are being obtained at an altitude of 3400 m in the northern subtropics and might be different with the globally averaged CO2 concentration at the surface.
Reduction in capacity of CO2 captured was due to the filling of SG pores with the ODA molecules that added on the SG surface.

In technological calculations, they are determined from empirical relationships [5] and tabular data [6].
Combinations of cutting data
To compare the results of the experiment with calculations based on reference data, statistical data processing was performed.
For the results for each method, 10 intervals of deviations from the experimental data.

By obtaining the data of BR1500 HS isothermal tensile test, it established a "" shaped part of thermal-mechanical coupled model which is based on ABAQUS to analyze the influences of forming speed and holding time on the forming properties.
Introduction With the development of Chinese automotive industry, energy saving, emission reduction, and safety and environmental protection have become a major trend in automotive development.
This paper designed sheet fixtures, using Gleeble-1500 thermal simulation machine to have an isothermal tensile test on the BR1500 HS high strength steel, using the obtained tensile test data to establish the " " shaped part of thermal-mechanical coupled model which is based on the ABAQUS software, then focused on the influence law of sheet metal forming speed and holding time to the "" shaped part forming properties. 1 The Tensile Test 1.1 Isothermal tensile test Test materials are ultra high strength steel sheet BR1500HS, which is 1.8mm thick.

By combining the experimental data of scanning electron microscopy, transmission electron microscopy and focused ion beam, the result suggests that the particle formation mechanism is highly correlated with factors of hydrophilic-hydrophobic properties of precursors.
Introduction Ceria-based materials are extensively applied in the fields of catalyst supports [1], carbon monoxide (CO) reduction catalysts [2, 3] and solid oxide fuel cell (SOFC) electrolytes [4, 5] because of their superior properties of thermal stability [6], oxygen storage capacity [2, 7] and ion conductivity [4], respectively.
The experimental data suggest that the hydrophilic-hydrophobic properties of the precursors influence particle morphology during the SP stages.

Hence, this method can be applied to rapidly and correctly find those dangerous positions and existing imperfections of its structure, thus providing valuable data to judge its structural rationality before practical manufacture, so as to make further improvements and optimizations for its structural design.
In actuality there is back flow in the meat grinder, this has been demonstrated by Huebner [3]; the material is churned within the channel instead of advancing uniformly forward, which causes a net reduction in the axial flow.
Using MATLAB 7.0 software multiple regression analysis of the data was performed to estimate coefficients in the Equation 1.

When the 2Si-B-3C-N ceramic was hot pressed at 1900oC for 10-30 mins, it exhibited large volume shrinkage, noticeable reduction of pores, and significantly improvement of density and mechanical properties.
On one hand, the high temperature and the large pressure may facilitate the plastic deformation, the viscous flow and the creep of powder particles, and hence accelerate the reduction of pores and the densification of the ceramic body.
The inference had been confirmed by our recent experimental data [18].

The purified ZnO nanospheres were functionalized using 3-aminopropyl-trimethoxysilane (APTMS) and made into core-shell nanostructures with in-situ reduction of Ag+ into silver nanoclusters.
The X-ray diffraction patterns are in good agreement with the standard data of ZnO (JCPDS PDF no. 361451).
Conclusion: In summary, high quality functionalized ZnO@Ag core-shell nanoparticles were synthesized using hydrothermal method followed by in-situ reduction of Ag+ into Ag nanoclusters.

However, the reduction in weakness still surpasses the sample that does not contain any RHA.
Throughout the testing, data were recorded on crack behavior and flexural strength for the determination of rupture modulus (MOR).
However, in terms of flexural behavior, which relies heavily on tensile strength, there is a slight reduction.
