In this paper, a peroxide-tertiary amine oxidation-reduction initiator system was used to synthesize a cross-linked polyacrylamide/bentonite composite at room temperature.
Fig.1 FTIR spectra of Na-bentonite, PAM, and the Na-BNT/PAM composite XRD.As seen in Fig.2, XRD test data demonstrates that the d(001) peak of natural Na-bentonite is 1.2455nm.
Conclusions A peroxide-tertiary amine oxidation-reduction initiator system was used to synthesize a cross-linked polyacrylamide/bentonite composite at room temperature.

Optimized interpolation procedures for the PGFs can be applied, resulting in a considerable reduction of matrix-filling time without any significant effect on the accuracy.
We compare the results obtained using our approach with the results obtained using the time-domain finite element method and the measured data.
A linear interpolation method was designed for the fast and accurate interpolation of 3-D PGF, resulting in a considerable reduction of matrix-filling time.

The results showed that catalysts improved the THMsFP reduction efficiency by around 18% for BAC step and reduced the effluent bromate by 20%-77%; reduced NH4-N to below 1 mg/L; The effluent COD met the national standard under all circumstances.
In this paper, pilot study was proceeded in order to supply reliable data and experience for productive application in serious source water.
Because of adsorption and reduction of surface reducing group on activated carbon, effluent BrO3- dropped to 5 μg/L and 8.3 μg/L respectively.

The major purpose is to systematically integrate the application of modularity in critical stages of product lifecycle and to facilitate the awareness and realization of modularity for manufacturing enterprise, so that the comprehensive benefits of modularity such as short time-to-market, parts number reduction, and high production efficiency can be realized effectively.
Gualandris [5] provides a framework that relates the adoption of postponement enablers (i.e. product modularity and process modularity) to the reduction of the negative impact of a supply disruption.
Modular architecture is expressed in the following Fig.3 in conjunction with a fridge case: Fig.3 Features of Modular Architecture Then comes to the detailed design of concrete module variants, and all essential module data shall be incorporated into CAD modeling environment for the preparation of module and interface design.

The calculated results show good agreement with the experimental data.
Applying the perturbation procedure similar to that in Refs. [12,13], the perturbation formulas of g factor and hyperfine structure constant for an octahedral 5d5 cluster can be expressed as: g = 2 (1 + 2kp)/3, A = P (κ/3 – 8Np /7) (1) Here kp and Np are the orbital reduction factor and the normalization factor for the π component, characteristic of covalency of the system.
From the cluster approach [14], the orbital reduction factors kp and ks can be determined by considering the ligand orbital contributions: kp = Np (1 + lpp2/2), ks = (Np Ns)1/2 [1- lpp (lps + lss w)/2] (2) Here w denotes the integral , where R is the reference impurity-ligand bond length.
Then the orbital reduction factors kπ » 0.857 and kσ » 0.461 are calculated from Eq. (2).
When the ligand orbital contributions were neglected, the theoretical results (Calc. a) are in poor agreement with the experimental data, especially the g factor and hyperfine structure constant are smaller than the observed values.

(6) Reduction in carbon dioxide.
After the 96 pieces of data were collected, one optimum combination was and applied on the green roof as planting substrate to evaluate the performance of thermal insulation.
Apart from the surface temperature, air temperature, relative humidity, solar radiation, and precipitation data were observed as weather conditions at a separate measuring station on the roof.
A GRAPHTEC data logger (GL-450AS) with 20 channels and a GRAPHTEC midi LOGGER (GL200-UM-151) with 10 channels were employed to record the data.
The data of September 13, 2010 are used for the detailed discussion because it has the highest temperature in that month.

On the contrary, the optimization-based approach requires only experimental or simulated data that can reduce energy use with a lower cost.
The Pareto plot obtained by engineering data mining, in which the data file is collected from the solution of the NSGA2 algorithm.
Collecting manufacturing data - Analysis of whole process chain In the first step, the profound analysis related to whole process chain is conducted.
The objective of this survey, a key starting point for research, is to gain not only an overview of the general on-site of target values but also specifically manufacturing data.
For this purpose, the relevant data was collected in the KOFCO company (industrial project partner).

Solar energy is a potential source for hot water and has been an important measure for energy savings and carbon reductions [1-5].
The blue and red data are solar heat gains and backup energy, respectively.
The carbon emission reduction can be calculated according to this equation Qco2=⊿Qsave*Y*Fco2/(W*ηw)= 94142.68×0.866×44÷(29.3×0.6×12)=11.4t;the carbon reduction for each household can be estimated by Qco2/18=11.4T/18=634KG.
