According to statistics, fuel consumption of automobile decreases by 6% to 8% while its weight has a reduction of 10% [1].
However, it is also observed that 2015 joint strength in 80℃ set achieves higher level than the RT set, and the general reduction range of -30℃ set for each adhesive is much larger than the 80℃ one.
Analysis of the experimental data leads to the following conclusions: 1) Through the shear strength tests of the SLJs with dissimilar adhesives, the experimental results are analyzed, and it is figured out that adhesively bonded joint strength is significantly influenced by long-term extreme temperature exposure.

It can be seen that the short treatment strategy results in drastic reduction of the microstructural scale regarding both the grain size and the precipitation scale.
The reported data is the set of stress–strain curves obtained by strain incremental cyclic tensile tests.
This progressive reduction of the recoverable strain, from higher than 3% to around 2% (Fig. 4.c), may be caused from the fact that the stress-induced α’’ martensite is progressively trapped by dislocations during the loading/unloading cycles.

When x=0.6 there is no reported data for decomposition of Mg0.6Al0.8Ti1.6O5 during heat treatment at about 1100 ˚C.
One of the most important reasons for using microwave energy is significant reductions in manufacturing costs due to energy savings and shorter processing times [10, 11].
The TG curves of dried gel that is presented in Fig. 1 shows an undulatory slope shape from beginning to 570 ˚C as a result of stepwise weight reduction of the precursor during dehydration, oxidization and decomposition [12, 14].

All these features also assist in PSCs cost reduction [9] as compared to inorganic photovoltaic cell.
At the same time spray coating is beneficial when it comes to reduction in wastage of polymer solution.
Based on this data, the annealing temperature during the experiment was optimised to 120 °C.

a reduction of the molecular weight or molecular weight distribution, will be discussed in detail.
The attempt to produce and stabilize homogeneous alloys at a molecular level by CMM demands, in the case of multi-component polymer systems, a dramatic reduction of chain mobility to prevent phase separation and the generation of free radicals by chain scission [9].
Thermal data and degree of crystallinity determined by DSC tm [min] Tm [°C] ∆Hcc [J/g] [J/g ∆Hm [J/g] [J/g] [°C] χc [%] Sample a 0 272.78 - 24.5 46 Sample b 3 268.35 2.9 26.0 43 Sample c 12 269.53 10.4 31.1 39 Sample d 30 268.47 13.1 29.6 30 The observed increase in cold crystallization enthalpy ∆Hcc for longer milling times is in good agreement with the WAXS results and is directly related to a lower degree of crystallinity milling.

The samples were then hot rolled at 850°C in ten passes to a height reduction of 86% and then warm rolled at 650°C in 25 steps to another 75% reduction.
A quantitative assessment of the final texture of the binary alloy A was not carried out due to a lack of statistical confidence in the EBSD data.

In the present computer model the thermophysical parameters corresponded to published data [2].
The carried out parametrical calculations have shown, that application of this shield assembly results to a reduction of a radial inhomogeneity of an axial temperature gradient near to LSI, but its values may be increased up to 45 о С/cm.
Also it increases an ingot cooling rate at 1150-1050 о С promoting a size reduction of the primary grown-in microdefects.

Readings of all of the LVDTs, strain gauges and load cells were recorded by an IMP data acquisition system.
Bearing capacity The experimental results are listed in Table 3, it can be seen from Table 3 that (1) compared to the beam B0, the crack, yield, maximum and ultimate load of the beam B1 is decreased by 5%, 4%, (a)B0 (b)B1 (c)3C0 (d)CAG0 (e)CAG1 Fig.3 Crack patterns of beams 5% and 3% respectively, but the crack, yield, maximum and ultimate load of the beam CAG0 is increased by 9%, 28%, 92% and 103% respectively, which indicate that 1) the reinforcement corrosion introduces the reduction of the bearing capacity of the RC beam; 2) the CFRP/AFRP/GFRP laminated hybrid fiber sheets can improve significantly the flexural bearing capacity of the corroded beam. (2) The crack, yield, maximum and ultimate load of the beam CAG1 is respectively increased by 14%, 35%, 102% and 109% compared to the beam B1, and is increased by 8%, 30%, 89% and 85% compared to the beam B0 respectively, which show that
strengthening with CFRP/AFRP/GFRP laminated hybrid fiber sheets can make up the reduction of bearing capacity caused by the reinforcement corrosion, and lead to the bearing capacity of the strengthened corroded column up to same level with the strengthened un-corroded column. (3) The crack, yield, maximum and ultimate load of the beam 3C0 is larger 29%, 14%, 14% and 19% than that of the beam CAG0 respectively, because the elasticity modulus and tensile strength of CFRP sheet is remarkably larger than that of the AFRP or GFRP sheet.

In the research, the quantification of human errors probabilities was studied generally, and was developed some achievements, such as HEART (human error assessment and reduction technique), THERP (technique for human error rate prediction), and SLIM (success likelihood index methodology)[9], and so on.
In first generation HRA practice, the quantitative assessment of a given operator task or error is emphasizing the nominal scenario context, such as Accident Sequence Evaluation Program (ASEP), Human Error Assessment and Reduction Technique (HEART), and Technique for Human Error Rate Prediction (THERP) [11].

Microbial remediation was achieved by microorganism that can survive in arsenic-contaminated soils, the mechanism of remediation include microbial adsorption, microbial reduction and oxidation.
Microbial oxidation and reduction used these microorganisms to change the valence state of metal ions, and thus the mobility of metal ions is diminished.
