The effect of higher temperature at butanol’s combustion is diminished by cooling effect as a result of its vaporization, which would explain the reduction of NOx emission.
For data acquisition and processing, the stand is equipped with an AVL acquisition system.
This decrease is due to the reduction of the temperature inside the cylinder as a result of more intense cooling effect produced by the butanol’s vaporization.

The XRD interpretation was done by comparison with standards in a PDF 02-8 data bank using the Bruker DiffracPlus software.
This may be attributed to the reduction in porosity by liquid phase formation due exclusively to the ash.
Furthermore, see Fig. 2, a significant increase in strength occurred at 1050ºC, which can be attributed to the aforementioned reduction of porosity by liquid phase infiltration [15].

The values for area reduction and elongation in each specimen were calculated by measuring both the initial diameter and the gauge length before and after tensile testing, respectively.
A fatigue crack propagation rate (da/dN) analysis was conducted using pairs of data comprising cycle number (N, in cycle) and crack length (a, in mm).

According to the data in some relevant materials, when adding rare earths into aluminum alloys, rare earths can not only form the compounds (REAl4) which has a role in strengthening the matrix with the aluminum, but form the stable intermetallic compound with iron and silicon.
These compounds are precipitated in the grain boundaries, which make silicon and iron concentration increased in grain boundaries and the reduction of the impurities in crystals, accompanied with the reduction of resistance and the increase of conductivity.

Experimental Procedure Three microalloyed steels were laboratory melted, reheated to 1250 °C, laboratory control-rolled from 80 mm to 13 mm thickness (approximately 50% reduction below 850°C), and air-cooled.
The HiC and HiMn alloys were nominally identical to the Base steel, except for the higher level of carbon in the HiC alloy (and a compensating reduction in manganese to maintain a similar Bs temperature), and a higher level of manganese in the HiMn alloy to suppress diffusional transformations and lower Bs.
EDAX-TSL OIM Data Collection 5.1 software was used for analysis.

However, present of an apparent defect on the surface of the thin films (observed using Field Emission Scanning Electron Microscopy) upon annealing at 160°C contributed to the reduction of remnant polarization.
The presence of “separations” on AN160 thin film caused a significant reduction in Pr , which was probably due to the observed defects observed in the film.

As to AgGO Alginate composite, after the microwave irradiation a new peak appeared at 260 nm, indicating the partially reduction of functional group of GO.
The data revealed that the Alginate layers was covered to graphene oxide and Ag nanoparticles simultaneously deposited on the cellulose with the size of 20 nm in size.

As the outside fiber undergoes a uniaxial compressive stress state, then the effective strain rate εei+1can be calculated using the radius reduction Δi-i+1 which is calculated using Δi+1=(ri-ri+1)ri×100%, as approximated in Eq. 18.
Er=4EEt(E+Et)2 (25) Similar with the calculation of effective strain rate, for a given forming temperature, when the material is drawn from rito ri+1, the outside fiber experiences a certain strain which can be calculated using the radius reduction, then the tangent modulus Et can be obtained using the CDM material model as shown in Fig. 4 (a) and the reduced Young’s modulus.
The stress-strain data for the AA5754 at different temperatures and different strain rates were input into Pamstamp via look up table.
