Their UV-Vis absorption and fluorescence spectroscopy data were studied.
The FT-IR data were obtained from AVATAR36-based Fourier transform infrared spectrometer.
The MS data were obtained with MAT95XP-based high-resolution mass spectrometer.
The data can make the electrode materials and luminescent materials and carrier transport materials between the sub-band matching, which can provides an idea theoretical basis for optimizing the device structure and improving device efficiency.
Table 1 data indicated that 5a-5f have relatively high electron affinity and ionic potential.

On the other hand, most such available data are incomplete: their focus is often limited to theoretical energy consumption and data on the machine tool infrastructure or potential emissions are rarely found [1].
Methodology In order to enable a consistent and accurate inventorisation and documentation of Life Cycle Inventory (LCI) data for a wide range of discrete manufacturing processes, a generic data collection methodology was developed within the CO2PE!
While the functional unit and system boundaries are set during the goal and scope definition, the real data collection effort occurs based on industrial measurements and comprises four different studies.
Often, reduction of standby consumption offers a large improvement potential.

The bearing capacity NsT and NbT can be calculated after the strength reduction coefficient at high temperature of the steel tube and steel bar are given.
At the same time, the axial load also affects the reduction coefficient of the bearing capacity of concrete.
The reduction coefficient of the bearing capacity of concrete is deduced based on the data fitting of numerical calculation results, which is as follow
On the contrary, the modification coefficient of slenderness ratio of the column with small diameter can be calculated following the below formula based on the data fitting of numerical calculation results.
Fig.2 Comparison of bearing capacity at high temperature between the calculation and test results Conclusions (1) Simplified calculation method of the bearing capacity of CFT columns subjected to fire at 150min and 180 min is presented to estimate the fire resistance based on lots of numerical simulation results and data fitting

The experimental results obtained by using expansive and shrinkage reducing agents were extremely encouraging in termsof free dryingshrinkage reduction, and even surprising in terms of flexural behaviour.
The slightly negative effect of SRA on mechanical performance is well-known on the basis of data reported in the literature [8, 9], indeed.
On the other hand, the addiction of SRA slightly penalized the flexural strength, as expected also on the basis of the compression stress,as well as on the basis of data reported in the literature [8, 9].
As you can see in Figure 3, the presence of expansive agent, with or without SRA, allows a reduction of 56-day drying shrinkage strains equal to about 30%.
The same positive effect was detected also by [10], which found an even higher reduction of roughly 80%.

Nanoscale zero-valent iron (NZVI) particles were supported onto activated carbon fiber (ACF) by impregnating ACF with ferrous sulfate followed by chemical reduction with NaBH4.
Fig.1b showed the SEM image of the NZVI particle made by liquid-phase reduction method.
The size of Fe immobilized in the ACF pores was smaller than a typical size NZVI made by liquid-phase reduction method.
Fig. 4d showed the result of application of equation (7) to the chloroform dechlorination data for ACF/NZVI.
The model provided an adequate fit of the experimental data.

Based on the data from Table 2, it is clearly indicates that the slump of the mixture is decreased when the amount of PET fibers content increase.
In compare to the rest specimens, the result shows the data was acceptable since still in range 19 GPa to 31 GPa and be able to consider acceptable according to BS8110 - 2: 1985.
To develop this nomograph, it’s needs several data of an experiment that has been conducted and analyzes before such as compressive strength, splitting tensile, water-cement ratio and volume fraction of PET.
The data obtained experimentally than compared with data obtained by using nomograph.
To ensure the accuracy of the new development of nomograph, the known data from previous studies are used to compare with data from nomograph as shown in Fig. 1.

The monitor data of 41 cities in our country indicated that 13 cities' groundwater have been polluted by nitrate, moreover the nitrate pollutant assumes a proliferation tendency to deep phreatic water day by day[11].
Figure 4 Nitrate concentrations(d=1.5cm) We may see from the data of above two groups that under the same condition of the anode and cathode material, the diameter of salt bridge and so on ,the influence rule of elimination effect on the length of salt bridge to the nitrate is that the relation between the speed of nitrate degeneration and the length of salt bridge is in reverse proportion, when the length of salt bridge is longer, the nitrate degeneration is slower.
Fig. 5 Nitrate concentrations(l=30cm) Fig. 6 Nitrate concentrations(l=35cm) Fig. 7 Nitrate concentrations(l=40cm) We may see from the data of the above three groups that under the same condition of the anode and cathode material, the length of salt bridge and so on, the influence rule of elimination effect on the diameter of salt bridge to the nitrate is that the relation between the speed of nitrate degeneration and the diameter of salt bridge is in forward proportion, the diameter of salt bridge is bigger, the nitrate degeneration is quicker.

Thus, as the storage period of single base propellants lengthens, the reduction rate of the tranquillizer content increases.
This paper presents a new methodology based on data mining and regression analysis for estimating the shelf-life of single base propellants using data from the ASRP to 105mm HE (KM1 and M1).
However, the R-squared value, 26.4%, indicates that the regression line does not sufficiently fit the observed data.
Conclusions In this research, we predicted the shelf-life of a 105mm high explosive shell (KM1 and M1) with a single base propellant using ASRP data.

XRD data were collected at room temperature on a Bruker D8 Advance Diffractometer using monochromatic Cu Ka radiation.
The reduction behaviour and the interaction of catalysts components were studied by temperature programmed reduction (TPR) using TPDRO1100 MS equipped with thermal conductivity detector. 4-Catalyst testing Activity of the catalyst was carried out in slurry-typed reactor.
TPR profile of catalyst, exhibits two reduction peaks, one around 200 °C and the other around 300 °C.
The reduction peak at 200 °C is due to the reduction of highly dispersed CuO and the reduction peak at 300 °C shows the reduction of bulk CuO [21-22].
Similar reduction behaviour of was also reported by Aguila et al [23].

A Combination of different denitration and desulfuration technologies is a inevitable trend for emission reduction of marine diesel engines.
But both of effective combustion control and emulsified fuel technologies can not meet the emission limits of 2g/kW·h regulated by NECA. 2.3.1 Selective catalytic reduction (SCR) SCR (Selective catalytic reduction) is considered to be one effective technology to reduce NOx emission of diesel engines.
Actual data shows that the SCR system can reduce NOx emission from 9.2 g/kWh to below 2.0 g/kWh. 2.3.2 Low temperature plasma assisted catalytic reduction (PACR) PACR is a new technology to greatly reduce NOx emission of diesel engines.
