Necker et al. [5] showed for OFE Cu rolled to reductions of 73% and 90%, that the strength of the Cube recrystallization texture component increases with increasing rolling reduction.
Methods Table 1 details the composites studied, their respective names, percentage reduction imposed and thicknesses of the Cu layers.
The orientation distribution function (ODF) for the Cu layers was calculated by the harmonic method from incomplete {111}Cu, {200}Cu, {220}Cu, and {311}Cu, pole figures using the Los Alamos Preferred Orientation Package (popLA) after correction of the data with respect to measured background and calculated defocusing error.

Energy analysis from the study shows that the integrated column arrangement which implement the side-stripper configuration achieved favourable result as it offers the highest percentage in energy reduction which is up to 68% (for reboiler) and 70% (for condenser).
Consequently, this can be linked to the reduction of operating cost for hot and cool duties and trim down the overall production cost for existing NGL recovery plant.
Conventional Distillation Columns of NGL Processing; (a) Deethanizer (b) Condensate Column (c) Depropanizer (d) Debutanizer The input data used in this study are based on actual operating conditions in the natural gas processing plant.
The design data generated from the simulation are tabulated in Table 3 and 4.
By reaching all the product specifications, the lower energy usage by integrated side-stripper column sequence promotes a more sustainable process and reduces the overall annual operating cost through the reduction of reboilers and condensers duties.

Studies have shown that the reduction of the cooperative work have a greater correlation with the width of concrete crack.
Therefore, model correction coefficient α and time- dependent comprehensive correction coefficient β can be proposed in accordance with the testing data of relevant parameters.
That means the resistance parameters of the actual structure are determined from theoretical calculation value multiplied by (α+βt), α and β can be obtained by regression method with test data of random variables at different time points.
The model comprehensive correction factor and the time-dependent comprehensive correction factor of each parameter have all been modified through the measured data.
(3) In RC beam, within the role of the aging factor, the reduction of average value of the shear capacity and increasing of its standard deviation both result in reduction of structural shear reliability

In the work, nano-sized MoO3 and unsupported MoS2 hydro desulfurization catalysts were synthesized using a novel hydrothermal reduction method.
Experimental materials and preparation methods Experimental materials By analysis and comparison,the hydrothermal reduction is used to prepare MoO3, the former body of MoS2 catalyst, and the MoS2 catalyst is synthesized by the hydrothermal deoxidization which is compared with the method of high temperature hydrogen sulphurization.
Materials of hydrothermal reduction to prepare MoO3(MoO3-Hy), of high temperature hydrogen sulphurization to produce MoS2(MoS2-D),and of hydrothermal deoxidization to prepare MoS2 have been shown in table1, table2, and table 3 respectively.

In order to achieve the objectives of the experimental study we follow several important steps, like assembly of medical data (the patient files and a survey of radiological images).
He underwent open reduction and internal fixation in the usual manner without any significant complications.
After fixation the fracture showed a good anatomic reduction.
In order to complete our study with some data about the effect of the metallic implants on the surrounding tissues, histopathological analysis was performed.
It is a stable assembly that ensure rigid fixation with endosteal vessels protection and anatomical reduction.

In general, inaccuracy of measurement data is less than the measurement data itself.
The number of measurements should be appropriately increased to prevent process error from polluting the measurement data.
