In this regard, the amount of ettringite reduced because of the reduction of hydrated calcium aluminate hydrated by slag.
On the other hand, the hemihydrate gypsum reacted with water rapidly to generate dihydrate gypsum, which cause volume expansion and resulting in strength reduction[5].

Processing to strain of 1.0 results in a fast reduction of the transverse grain/subgrain size to about 300 nm.
Further deformation up to the largest applied strain of 7.2 does not lead to significant reduction of the grain/subgrain size, which Strain, ε 0 2 4 6 8 Hardness, Hv (MPa) 1000 1500 2000 2500 3000 3500 4000 Subgrain Size, d (µm) 0.0 0.2 0.4 0.6 0.8 1.0 1.2 Fe - 15%Cr Hv dapparently stabilizes at about 200 nm.
The data were obtained by EBSP technique.
The relationship between the Hv and the d is represented in Fig. 6 including the data for a relatively coarse grained sample.

For instance, when Re=100 there is vortex-shedding period and the Strouhal number is computed and compared with literature data [2].

Configuration design The main steps of modeling are as follows: The basic configuration data of body-wing integration back-swept wing is obtained from reference [3], and the numerical calculation analyzed.
Coefficient CL CD K mZ Data of reference [3] 0.4685 0.0261 17.982 -0.9756 Configuration of forward-swept wing 0.5038 0.0212 23.784 -0.8185 The calculation results show: compared with back-swept wing configuration in reference [3], under design state, the forward-swept wing rise coefficient CL is higher, which meets the design requirement, while the resistance coefficient CD is lower, rise resistance ratio K increases obviously, and reaches 23.783, pitching moment coefficient reduces from the original 0.9756 to the initial configuration to 0.8185.
Compared with the initial tailless back-swept wing configuration, the increase of tailless back-swept wing configuration comes from the increase of lateral wing power improvement, upper and lower surface pressure difference increase and central body upper surface suction; while the reason for resistance reduction, on one hand, the wing surface wing rear suction decrease leads to wave resistance reduction, on the other hand, the span quadrature bigger, the induced resistance smaller.

Superoxide dismutase (SOD) activity assay: SOD activity was determined based on its capacity to inhibit reduction of nitroblue tetrazolium (NBT) by superoxide radicals generated by xanthine-xanthine oxidase [11].
One SOD unit was defined as the amount of extract that gave 50% inhibition of NBT reduction.
Statistical test of data.
For all data collected SPSS 11.0J for Windows: Two-factor analysis was used.

The existing data primarily concerns the shaping of thin steel sheets for deep pressing, and there is frequently a lack of detailed information regarding their mechanical properties [5].
In addition, there are no data on the edge eversion of laser-cut holes.
During eversion, the edge diameter increase occurs at the expense of a reduction of wall thickness.
Furthermore, the use of different punches allowed for the reduction of the eversion forces.

During each test, relationship between load and corresponding displacement were continuously recorded in time by an automatic data acquisition system using a microcomputer.
A 92.31% reduction in gross-section tensile strength is observed for a notch size 46 mm compared with the un-notched specimen.
The net-section strength is reduced from 93.38 to 44.26 from notch size of 0 mm to 22 mm, but no further reduction is observed as the notch size increase to 46 mm. this critical notch size will be influenced by specimen boundaries, which have an effect on the stress intensity factor, and therefore only applicable to the current data set.

Given its large geological reserves and attractive development prospects, many countries as a CO2 emission reduction, to reduce the dependence on oil and gas, and join the first selection of fossil energy and new energy.
The generated and stucked hydrocarbon in the mud and shale to hydrocarbon expulsion presented dynamic equilibrium, namely the formation of hydrocarbon and shale gas content in formation keep balance, shale gas content and expulsion keep balance. 5.2 seismic exploration technology The main use of a variety of seismic data, understanding complex structure, reservoir heterogeneity and fracture zone; determine lithology and identify shale formations; through coherent analysis, seismic attribute analysis, inter-layer slicing prediction shale crack to improve the success rate of exploration. 5.3 Logging exploration technology Through log data can complete quantitative analysis of the reservoir lithology, determine to the basic evaluation parameters of reservoir, such as porosity, permeability, gas saturation, reservoir thickness. 6.
However, according to statistics show that only a small number of well-developed natural fractures can be used in shale gas development and production direct, more than 90% of shale gas well needed fracturing to communicate naturally fractured, improving conductivity near the wellbore. 6.2.1 Water fracturing technology Hydraulic fracturing technology uses water to add the appropriate drag reduction agent, clay stabilizers and necessary surfactants to replace the traditional gel fracturing fluid.

Therefore, this research is done to contributing on reduction of carbon release by reducing the usage of internal combustion engine without sacrificing the performance of the motorcycles.
The reduction on engine’s power contribution is happen when charge flywheel is connected to the drive axle mechanically through clutch system automatically.
Data explained is referred to the graph below.
The ideal power traction is use as a base data for comparison of both systems in transfer power to the wheel.

UV treatment of the ion-changed film leads to the reduction of metal forming a metallized polyimide films.
In the first step, the surface of polyimides is chemically modified with potassium hydroxide (KOH) into potassium polyamate via imide ring-cleavage reactions, which was designed according to the reported data that the surface of the native polyimide can be modified by base hydrolysis [4].
Thermal curing induced an internal silver ions reduction, and then their agglomeration and migration yielded the metallized surface.
Selected data for silvered PMDA/4, 4'-ODA films Summary In conclusion, silvered polyimide films can be easily fabricated with double excellent reflective and conductive surfaces, outstanding metal-polymer adhesion, high mechanical properties, controllable thickness of silver layers and modest cost, by surface modification and in situ self-metallization method.
