For manufacturing of firmly bonded ceramic joints via glass solder, a portion of the samples was joined using a high temperature oxide furnace (Nabertherm) in air atmosphere.
Precise data on geometry and base material are given in table 2.
For both considered laser joints, heat treatment is presumed to be responsible for dumping inner stresses leading to reduction of strength scattering.
A major strength reduction was observed due to large pores or pore fields (nonsufficient joining), whereas higher strength was found for minimum pore proportion.

At this strain, only one element showed severe reduction in Ic,
indicating that almost all filaments were damaged within the length (10 mm) of this element, while
the other elements were not damaged and retained the original Ic.
On the other hand, in the case of bending strain (Fig.5), as the exerted stress varies from tensile to compressive along the thickness direction, the reduction in Ic and the damage evolution with increasing bending strain gB was gradual.
From the regression analysis of the Weibull plot (plot of lnln{(1-F) -1} against ln(Ic-Imin))of the experimental data, Imin, I0 and m were estimated to be 28 A, 15 A and 4.6, respectively.
With the present method, the Ic and n-value of long sample, which are difficult to be measured in laboratory, can be predicted from the data for short samples which can be measured in laboratory.

Introduction
Magnesium (Mg) is a preferable lightweight metallic material and shows great potential to be applied in transportation and aerospace industries as structural components, leading to significant weight reduction [1].
Since slippage and thickness reduction during HPT are negligible compared with the shear strain, the shear strain γ can be calculated using an equation [8] shown below: (1) where r is the distance from the center, θ is the rotation angles in degree, and h is the thickness of the disc specimen.
All the data points lie on an unique curve.
(b) The hardness data re-plotted as a function of the shear strain (γ).

To improve the accuracy of the data, testing two faces of per sample and an average value was reported.
In this present investigation, the electrical conductivity data in percentage of the International Annealed Copper Standard (%IACS).
Therefore, the G peak can represent the degree of reduction, doping degree, and doping type of graphene.
The reason why such an alteration occurs is that a significant reduction of Cu atoms concentration in precipitates free zones (PFZs) and segregation of Cu atoms along grain boundaries.

This conceivably can lead to a higher level of economization and
cost reduction by avoiding waste and real-time adjustment of process parameters.
The electrode covering layer used for all measurements led to a reduction of the signal interval but even though a very clear examination of sample dynamics is possible.
Furthermore, the use of the derivation of above mentioned quantities can be directly correlated to the data generated by DSC.
Further investigation is foreseen for the analysis to create a formalism for the evaluation of crystallization and / or curing index using dielectric data that is desired for the online application of this technology.

As a result, the data of the residential living environment including productivity, energy consumption and other information could be displayed directly in real time.
Therefore, the data of residential capacity, energy consumption and environment can be displayed on the screen and presented though 3G mobile phones.
This will help to promote the technology development, as well as progression of energy conservation and emissions reduction [6].
Products can be understood visually, and thus enhances the initiative of green consumption, energy conservation and emission reduction, the concept of sustainable development.

The ingots were first hot rolled and subsequently cold rolled to reach a cold-rolling reduction rate of about 50%.
Hollow points represent data corresponding to the inter-critical heat treatments, whereas full points are the samples annealed in the fully austenitic domain.
In addition, the effect of micro-alloying with Nb is also assessed through the data in Fig. 3.
The resulting grain size reduction from the increase of Mn-content may be explained due to the dragging effect [13, 14].

For applications depending on force-fit, creep of polymers can pose problems due to preload reduction in joints.
Examples include the “Advanced Composite Cargo Aircraft” by Lockheed Martin, which demonstrated a 90% reduction in the number of structural components and fasteners compared to a traditional metallic design through the use of bonding processes [2].
Detailed data on the prepreg and the corresponding experimental results have been presented elsewhere [9], therefore the emphasis of this paper is on the analysis of the RTM samples.

All the experiments of CuNPs-Pl synthesis and optimization were performed in triplicate run whereas antimicrobial and antioxidant assays were experimented in five runs and data was statistically expressed as mean ± S.E.
It is believed that the reduction process is increased as the volume of extract increases which is responsible for fast nucleation resulting in the small size nanoparticles.
Several functional groups have been revealed in the FTIR spectral data of PlL and CuNPs-Pl as shown in Fig. 4 (A).
DPPH assay principle involves in the reduction of DPPH radical to DPPH-H non radical form which indicates from the color change from purple to yellow.
