Several adsorption isotherms include Langmuir, Freundlich and Dubinin–Radushkevich(D–R) were used to fit the equilibrium data.
The adsorption kinetic data of Cr(VI) were analyzed and was found fitting well in pseudo-second order equation.
The conformity between experimental data and the model-predicted values was expressed by the correlation coefficients (R2).
Several adsorption isotherms namely Langmuir, Freundlich and Dubinin–Radushkevich(D–R) were used to fit the equilibrium data.
The experimental data fitted well to the pseudo-second-order kinetic model.

For identification purposes of crystalline phase composition, diffraction pattern obtained were matched with standard diffraction data (JCPDS) files.
Results and Discussion According to the thermodynamic data, complete carburization of metallic Fe with carbon monoxide may occur in two possible equations that have been shown in the Table 1.
The TPR profile for Fe in non-isothermal reduction under 20 % CO in nitrogen is shown in Figure 1.
It was found that the carburization rate was affected by change of surface conditions and surface area by reduction, degradation, and cracks at high temperature [16].
The comparison of different temperature with the XRD data revealed that the carbon peak is obviously appear as temperature is 500 °C because of Boudouard reaction.

A reduction in the acid value is desired.
There is an overall positive effect when the acid value is justaposed with the levels of reduction achieved in peroxide value.
The reduction in the peroxide and saponification values agrees with these observations.

The research will have the practical directive function about realizing the energy saving and emission reduction of carbon dioxide, transforming the mode of economic development and improving the wood’s carbon storage.
So studying the emissions reduction of carbon dioxide is imperative, which in order to alleviate the greenhouse effect and maintain the ecological balance during the large environment of transformation from world economy to low carbon economy.
The measures will contribute to protect and use wood resources efficiently, and provide data support for creating the trees’ high quality cultivation measures.
The Data Processing and Analytical Method.
It analyzed the wood’s anatomical characteristics, physical characteristics and chemical characteristics to study the law of wood carbon storage, and provided important basic data for improving the wood carbon storage capacity and optimizing the carbon stock system.

Liquid chemical reduction method was used to fabricate silver/hydroxyapatite nanoparticles (nano-Ag/HA) by depositing nano-Ag on the surface of hydroxyapatite nanoparticles (nano-HA).
Díaz [14] fabricated nano-Ag/HA by a colloidal chemical route and subsequent reduction process in H2/Ar atmosphere at 350˚{TTP}730 C.
Nano-Ag/HA was fabricated by liquid chemical reduction method and the typical process was as follows.
The diameter of ZOI is larger than the reported data by Díaz [14] and Nirmala [15], suggesting that the composite dressing has a strong antimicrobial activity, which can be contributed to the small sizes and good dispersity of nano-Ag on the surface of the alginate dressing.
Fig. 4 Antimicrobial property of Ag/HA/alginate dressing Conclusions In this paper, nano-Ag/HA was fabricated by a liquid chemical reduction method.

Firstly, according to the characteristics of the network decomposition and the shortest route algorithm, adopts an array as the network data storage method.
Network data storage based on array The paper takes generalized cost as the arc weight of the shortest route computing.
The data storage structure is shown in Table 1 according to the sparsity of the network, which directly affects the data searching speed used for network decomposition and the shortest route computing.
(3) Refining reduction of the original network.
Network refining reduction refers the staged reduction from coarsening network to the original.

The collector-dryer system has been equipped with data acquisition system to evaluate the performance, such as a data logger, K-type thermocouples, and air velocity measuring equipment.
All temperature data were recorded at an interval of one minute by a data logger.
The relative humidity of air inside the dryer was determined from the dry bulb and wet bulb temperatures recorded by a data logger.
The solar radiation data and other meteorological data were obtained from the Mechanical Technology Workshop Station at Vallaya Alongkorn Rajabhat University, Patum Tani.
The reduction of moisture content was estimated at 17.64 MC (% w.b.) within 6 hours.

The initial data for calculation included temperature, pressure and also the full set of substances to be considered.
Data presented in Table 2 for the pressure 0.4 MPa corresponds to a more narrow temperature range, but the temperature step is 10 K.
These data allow to obtain the graphic dependence of equilibrium component contents in more detail.
The calculation data obtained allow to estimate the dependence of the temperature of "full" MnO to Mn reduction related to the pressure in equilibrium system.
Conclusion The numerical data obtained in the work allow to predict the metal (Mn) output in the temperature and pressure ranges specified.

As formwork accounts for about 25 percent of the entire duration of a construction project, including nuclear power plant construction, and requires considerable efforts, to achieve a reduction in construction duration, it is necessary to reduce the duration of formwork.
Therefore, we investigated a case site of an AL-Form applied nuclear power plant in Korea to obtain fundamental data on the applicability of AL-Form to nuclear power plants.
However, in comparison with the increase of construction cost, the material arrangement and cleaning cost was decreased due to the reduction in consumable materials and wastes achieved through the use of AL-Form.
