Calcium-based stabilizers (CBS) such as lime and cement are used to improve engineering properties of soil and achieve desired soil properties resulting in the development of strength and reduction in soil plasticity [3].
Several studies have acknowledged that sulfate-rich subgrade soils stabilized with CBS are susceptible to strength reduction, volume swelling stability, and other issues due to adverse reactions between the sulfates in soil and CBS [5, 6, 7].
To obtain more accurate data, each mixture was tested three times, and the average value of UCS was recorded.
Also, the strength reduction in the mellowed soil mixtures could be attributed to the decrease in the MDD of soil after mellowing process [13].

The specific capacitance (Cs) value was calculated from the CV potentiostat data using Eq. 1.
The higher specific capacitance of HC-2 is caused by the holding initial temperature at 100˚C for 4 h can prevent lignin degradation and support the reduction of KMnO4 to MnO2 by lignin [16].

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.

Using the Solidworks program, then prepare the CAD data to import into the Cast-Designer program.
The reduction is notable in the X-axis by 17 millimeters, with no change in the Y-axis, and a decrease of 3 millimeters in the Z-axis.

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.
Material properties used in this study Young's modulus [GPa] Poisson's ratio Yield strength [MPa] Tensile strength [MPa] Adherend 210.0 0.30 120.8 300 Adhesive 2.70 0.33 56.7 61.3 Title of Publication (to be inserted by the publisher) reduction of adhesive thickness have the limit strength corresponded to the thickness to make an contrary influence, therefore in this study the limit thickness of adhesive and adherend is in 95-100 µm.
Fracture behaviors according to various adhesive thickness Title of Publication (to be inserted by the publisher) crack, therefore not a stress intensity but inner deficiency causes strength reduction primarily.

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 reduction of the human presence is also desired to avoid health diseases caused by the emission of volatiles during the resin reaction.
It was concluded that the regular packing assumption does not succeed to predict experimental data in real fibrous beds, due to the effects of the non-uniformity present in the fiber arrangement.
More specifically, if the generation of the initial cell fails due to the violation of the above constraint for a certain number of trials, the cell is considered as not generable using the considered parameters and a new cycle starts after the reduction of the standard deviation.
In particular a general reduction of the transverse permeability has been observed with respect to the initial regular cell.

The results obtained with the proposed approach are compared with experimental data on a reduced scale tunnel lining structure subject to ESA.
As no specific data on the concrete used in [1] are available, the material parameters have been fixed within the range calibrated on the basis of the experiments reported in [13].
Figure 6 reports the evolution of the overall stiffness reduction, accounting for both chemical and mechanical damage of the measurements points indicated in Fig. 4.

In this paper, a methodology of modeling and simulating the electro-statically driven micro-electromechanical systems (MEMS) is presented, utilizing topography data with an arbitrary structure.
Consequently, the reduction in the order of the numerical integration is expected from the original order to lead on improved result [9].
