The kinetic data were evaluated by the pseudo-first-order, pseudo-second-order and intra-particle diffusion model.
The experimental data were well described by the pseudo-second-order model with r2=0.997.
Fig. 3 shows that the experimental data is best fitted to the pseudo second-order kinetic model.
Table 1 shows various data obtained from two different kinetic model.

The diffusion-controlled deposition mechanism is based on the reduction of anionic MnO4 at the cathode surface.
The experimental data presented in Fig.1 showed lower deposition yield from the 0.1 and 0.15 M KMnO4 solutions compared to that obtained from the 0.02 M KMnO4 solution at a current density of 2 mA/cm2.
A small reduction in sample mass was observed during anodic pulse, applied after cathodic pulse (Fig.2 b).
As a result, the reduction in charge storage properties was observed.
Summary Manganese dioxide films were prepared by cathodic reduction of 0.02-0.15 M KMnO4 solutions.

Each alloy was prepared with two different cold rolled reductions.
Two different cold reductions (CR) were performed.
LCR 1020 is SAE 1020 with 39 pct cold reduction.
Figures 2a-2b show the reduction in pearlite band width with greater cold reduction.
The data in Table 1 also show that a slight decrease in Ac3 was observed in both LCR and HCR 15B25.

This temperature was chosen on the basis of thermogravimetric analysis, revealed both dehydration and reduction processes ranges [4].
According to the electron diffraction data iron particles in all the samples are coated with amorphous SiO2 layers with thickness of about 3 nm.
Thus the complete reduction at MM homogenization procedure has not been achieved.
Mossbauer spectra and corresponding phase contribution for nanocomposites, obtained in course of precursors reduction in hydrogen at 400oC.
It cannot be explained by iron concentration only in accordance with Mossbauer spectroscopy data.

Different methods reported for the N2O control at the tail gas of industries include thermal decomposition, selective catalytic reduction and catalytic decomposition.
XRD data were analyzed for phase identification, presence of impurity phase, as well as for structural damage if any during the catalyst preparations.
During the content of Fe is 1%, as shown in Fig. 6, this sample itself displays a distinct H2 reduction peak at 450 0C, which can be assigned to the reduction peak from Fe3+ to Fe2+, and in the existence of Fe3+.
Meanwhile, it shows another weak H2 reduction peak at 570 0C, which can be assigned to the reduction peak of Fe2O3, in the existence of Fe2O3 partly.
With the increase of the contents of Fe ions, the shift of the H2 reduction peak to low temperature occurred, and the drastic increase of the signal of H2 reduction peak of Fe2O3 were also observed.

To further understand the way companies in Thailand implement Lean manufacturing to improve their quality performance, a research observing and gathering data from expert opinions was conducted.
Production Planning and Control Small lot production(5), Storage space reduction(6), Use of Electronic Data Interchange with suppliers (EDI)(4), Kanban system(6), Pull production(6), Mixed model manufacturing/scheduling(8), Synchronize system(1).
Lean manufacturing tools and techniques that useful for the production planning and control department, can be classified into six main areas: mixed model manufacturing/scheduling, storage space reduction, the Kanban system, pull production, small lot production, and use of Electronic Data Interchange (EDI) with suppliers.
To complete the investigation of Lean implementation in Thailand, it is necessary to collect the data regarding the Lean implementation of suppliers as well as investigates the linkage between supplier and producer.
Toyota has ability to control and interchange data which are the important key for implementation of Lean concept.

Working methodology consisted in processing literature data and data obtained from author’s experimental research on the environmental impact of EDM.
As a consequence, the reduction of energy, resources end noise demands is an essential key to improve the environmental performance of industrial manufacturing processes.
However, some applications for reduction of environmental impact are relevant to EDM as the following paragraphs illustrates.
There are no data available regarding the environmental performance and related savings potentials of EDM machine tools considering the multitude of design options identified and subject to assessment.
The reduction of environmental impact of manufacturing processes demands accurate knowledge about the existing material and energy flows as well as the origins of associated environmental impact.

The coastal forest is not only economically best in mitigating tsunami, but also acts as a natural way of tsunami disaster reduction [4,5].
The amount of energy reduction changes by the density, structure, and configuration of vegetation [10].
The crown part of vegetation is very important and strongly effects the amount of waves energy reduction in coastal regions.

The percent volume reduction was selected at the beginning as being 20 %.
Results of the topology optimization for the percent volume reduction of: a) 20 %; b) 30 %; c) 45 % Femap NX Nastran offers the possibility to analyze the numerical data on a series of graphics as the ones presented in Figure 6.
The lowest value of stiffness resulted in the case when a percent volume reduction of 20 % has been considered (see Figure 6a).
Weight of the component in accordance with the loading force and the percent volume reduction coefficient By analyzing the results presented in Table 1 and Figure 7, it is possible to observe that by increasing the value of the loading force and percent volume reduction coefficient, in both cases of material type that were considered, the weight decrease is significant.
Taking into account the fact that more than 200 components like this are mounted in an airplane, the fuel consumption reduction is also significant in this case.
