In order to confirm this
fact, the debris particles were analyzed with ICP-AES for their typical element contents, EPMA for
the homogeneity of the solid solution, XRD for the chemical compounds, and TGA and hydrogen
reduction analysis for the percentage of the debris oxidation and reduction.
The data in Table 1 was collected for the tests in which the hydrogen contents after the interaction were 10 times higher than those before the interaction.
- Hydrogen Reduction Analysis The debris sample was heated at 2073 K in a hydrogen atmosphere for 12 hours.
If U3O8 exists in the debris, the total weight of a sample will be decreased by its reduction.
The uranium in the debris might have existed in the form of UO2, by considering the reduction ratio of the peak and the shifted peak pattern.

Abstract.
Our tests show that our design is applicable to most chrome extensions (those not using the jquery library) and achieves a reduction in TCB up to 77 percent for our examples.
In the two examples we measure (a) the reduction in TCB after using our architecture, (b) the amount of code need to be changed in order to retrofit the application, and (c) performance overheads (load latency, communication time, the interposition time by policies, and memory consumption).
Our evaluation shows that we can apply our architecture to most chrome applications and achieve significant reduction in TCB with no more than 18 lines of change for the chrome extensions we studied.

It not only achieves carbon reduction, but also promotes community well-being.
The carbon reduction is the one of important global issues right now.
The output signals are averaged in terms of 140 data.
This research eliminates the complex action of pulling plug off that results carbon reduction by decreasing standby electric usage, and it is also benefit for handicapped or senior people to control the power supply switches more easily.

Data for concrete production were obtained specifically for this study in a Portuguese industrial facility and are registered in Table 1.
As the data for the background processes and for internal transport and electricity used in the industrial facility was not available, the analysis was carried out with data from Ecoinvent database [12].
If the scope, assumptions, data quality, scenarios or LCIA method chosen varies from one study to the other, the LCA results will be different.
In this phase of the material characterization, one can state that the concrete with fly ash incorporated may be classified as an eco-material (eco-concrete) considering that the environmental issues that are minimized are waste reduction, reduce of landfill problems and resource saving by the utilization of recycled materials.

At 1100 °C (Fig.2), it was possible to observe a significant reduction in porosity in the samples with increased content of Ti-Al, mainly in relation to the macropores.
The density analysis proved the reduction of porosity and increased densification due to increased content of Ti-Al in the samples, a trend previously demonstrated in the microstructural analyses.
Fig.5 presents graphics with the data of density for samples sintered at 1100° C and 1400° C.
