Test on the temperature reduction performance.
Study the temperature reduction performance through infrared radiation test.
Fig.5 The temperature data of the infrared radiation tests (pc: the powder content) The equilibrium temperature is shown in Figure 6, which is the average surface temperature between 52min~60min.
Visibly, the high air humidity is to the disadvantage of temperature reduction
Conclusions A new type of low-heat accumulation asphalt mixture has been made to study its temperature reduction performance and pavement performance.

To achieve this goal, cost reduction through the use of lower cost feedstock and the minimisation of processing steps is essential.
In addition, some data on recent DuPont powder is also presented.

MAP treatments could postpone the increase of TTS, inhibit the reduction of TA, and avoid the decrease of flesh firmness.
Data analysis was done by an analysis of variance, with mean separation by 0.05 levels.
Many researches support that low O2 and/or high CO2 can retard the reduction of organic acids in plant tissue.
MAP treatments could postpone the increase of TTS, inhibited the reduction of TA, avoid the decrease of flesh firmness, however, MAP couldn’t maintain ascorbic acid.

The obtained experimental data for the various composition alloy Co-Mo-W are compared with respective indicators for individual metals.
The alloy formation mechanism provides for an oxide film formation by partially reduced refractory metals, which subsequently contributes to the reduction of oxoanions by atomic hydrogen to the metal state [26].
Based on the data obtained as per the known value of the corrosion current, the corrosion rate depth index was calculated according to the equation: (1) kall – electrochemical equivalent of a metal or alloy, kg/C; jcor – corrosion current density, А/m2; ρall – alloy density, кg/m3.
As evidenced by the data specified, with the total content of refractory components in the ternary alloy Co-Мо-W at the level of ω(W+Мо) ≈ 25–30 mas. % spheroids composed of built-up crystallites of a size up to 600 nm form.
According to the data of the specified graphical dependency, the highest values of the exchange current density for the coatings studied were obtained in an acidic medium, while in alkaline and neutral media this index decreases by more than an order.

The corrosion modelling for iron structures The particular chemical composition and the lack of experimental data makes the application of a damage range for the characterization of the factors necessary.
These curves are obtained by processing experimental data recorded in a time interval for different environments opportunely extrapolated over a long period.
The structural model of iron roofing In order to assess the seismic response of the Umberto I Gallery roofing, a numerical model has been developed, on the basis of available data.
In Fig. 6 there is the data estimated until today (115 years) in terms of thickness reduction, to use for an analysis of the gallery [4].
In order to evaluate the effects of corrosion, the maximum values for the thickness reduction have been also assumed.

The reduction of DOC by preozonation was due to the possible mineralization of NOM.
For the two treatment trains, a greater reduction of UV254 was achieved in Train 2.
SUVA values were shown in Fig. 4, based on the data of DOC and UV254 in Fig. 2 and Fig. 3.
These surrogate parameters got another reduction by the following processes.
But the application of preozonation resulted in a significant reduction of UV254 and SUVA.

After the normalization for the elastic anisotropy (altered W-H analysis), the data showed a very good linear behaviour.
The decreasing of the Full Width of the Half Maximum (FWHM) of the peaks can be related to reduction of the average microstrain and/or to the increasing average dimension of the crystallites.
The percentage of reduction of microstrains after the thermal treatment was calculated according to the equation: Fig.2.
Linear interpolation of data with the W-H equation (a) and with the modified W-H equation (b).

ESED plays an important role in the reduction of earthquake disasters and emergency evacuation to a safe place for resettlement of affected people.
Update Data Management.
Earthquake emergency shelter in the information management is the main data to update and maintain, this is mainly aimed at the earthquake for the department.
Through the update data management, guarantee the data in the database of the dynamic add, delete, modify and real-time update, keep database data processing.
Along, but also to the existing database backup, to prevent data loss; at the same time, but also provides online help, can help users solve in use process possible problems.

Some tension specimens contained strain gauged rebars to obtain very detailed data concerning reinforcement strain distributions.
How rapidly this reduction occurs has not been studied.
A collaboration between Leeds and Durham Universities seemed a good way of generating the best possible range of experimental data.
The very fine wires from the gauges (three per gauge, each 0.2mm diameter) were connected to wiring harnesses which led to the data logging instrumentation.
The detailed nature of the Durham data, indicated in Fig. 3, showed how strains peaked at the crack positions and then declined between cracks due to the tension stiffening effects.

Misorientation analysis, using EBSD data sets, has enabled us to constrain better recrystallization mechanisms in rocks and minerals.
Such data enable us to quantify the conditions in the upper part of the Earth. 2.
Such data are essential to dynamic models of the Earth.
Dispersion of EBSD data, by rotation around rational crystallographic directions, reflects deformation by dislocation creep and recovery.
