The experiment method is to blend air and CO2 properly through MFC (mass flow rate controller) and to collect each data by changing mole fraction of CO2 at 0%, 15%, 30% and 100%.
2.2 Experiment Results
Fig. 1 is the test result of TGA experiment and shows the mass weight reduction by changing CO2 concentration atmosphere at the time of calcination.
As density of CO2 is increasing, reaction starting temperature is getting higher and seemed not to be formed in that a precursor which is synthesized at 100% CO2 density is 5% less than air atmosphere in mass weigh reduction .[13] Fig. 2is the result in which heat exits of total precursors analyzed by DSC (differential scanning calorimetry) was measured.
Fig. 3 is the plot to get the k value based on data which is acquired in TGA.
The reaction rate should be defined in electronic data processing interpretation for chemical reaction and k value which is achieved by the experiment was used for electronic data processing interpretation of a calcination furnace.
It was found that CO2 concentration decreases by loading layer at the time of vent formation and more reduction was made as the loading layer is more.

In this paper, finite element software are used for the CTOD test specimens to simulate the characteristic values, then compared with the experimental data to draw the appropriate conclusions.
The calculation of fracture toughness is a very comprehensive issue, it need to consider the complex boundary conditions, while the geometry, material nonlinearity, large deformation processing brings considerable difficulty for these issues. with the reduction in the costing and the substantial increase in computing speed, the finite element method for high precision calculation to solve the problem of computing has become the first choice.

According to study mixing of chemicals with red onions, it was found that red onions mixed with chemicals are bruised leading to reduction of red onion’s value.
Results and Discussion Based on Research Objectives and Hypothesis 1 According to data analysis on innovative demands, it was found that the prototype of the red onion chemical mixing machine had 2 aspects of demanded features for production efficiency, i.e., the structure of the red onion chemical mixing machine and the usability of the mixing machine for improving the product volume as well as for strengthening products, improving its durability, and replacing human labors.

Single reduction, Gp, total reduction, Gc, ad drawing speed, v, are summarized in Table 1.
Data presented in Figure 2 shows that in the multistage drawing process in hydrodynamic dies the increase of drawing speed causes intense heating of a thin surface layer of the wire to the temperature exceeding 500°C.
In fact, under both laboratory and industrial thick layers of lubricant generally do not cover all edge roughness, thus with an increase in the total reduction roughness of the wire decreases.
The change in lubricant pressure p as a function of drawing speed v for different coefficient of dynamic viscosity η=50, 150, 250 The data presented in Fig. 8 shows that the lubricant pressure in the hydrodynamic drawing process at a constant of the resistance die parameters is dependent on the product of the drawing speed and the dynamic coefficient of viscosity.

Three
different gases of analytical grade were used: N2 for inert atmosphere, an air mixture for oxidation
and Ar/4%H2 mixture for reduction.
The data have been expressed in mg/kg, as proposed in the NEN standard (Fig. 1a), and in µg/m 2, where the specific surface of the calcined BR has been used in the calculations (Fig. 1b).
Unfortunately, the evaluation of the system under study is hindered by a number of parameters: a) the host minerals for Cr, Ni and V are not known since BR has been produced from gibbsitic and diasporic bauxites with unknown trace elements profiles, b) as a consequence, the thermodynamic data for solubility are not available, and c) the redox reactions taking place can be identified only for major phases, i.e. hematite, and only estimations can be made for the interplay of the different minerals within the bulk and with the gas phase.
Ox: Oxidation, In: Inert, Rd: Reduction.
A sensitivity analysis of the model [19] demonstrated the significance of the wall material's density: a density of 1000kg/m 3 would impair a higher than 30% reduction in the calculated dose rate.

Cold rolling was
conducted without intermediate annealing to over 90% reduction in thickness.
The Nb and/or Cr added Ni3(Si,Ti) alloys as well as the Ni3(Si,Ti) alloy were successfully cold rolled to more than 90% reduction in thickness without edge cracks, indicating that Nb and Cr addition did not spoil cold-rolling workability of the Ni3(Si,Ti) alloy.
The data for the nickel based alloys (Inconel X-750 and Hastelloy X) and stainless steels (Type 340 and Type 430) that were referred from the literature [6] are also included in this figure.
Data for the conventional nickel alloy (Inconel X-750) and stainless steel (Type 310) are also included in this figure.
For all the alloys, cold-rolling with over 90% reduction in thickness was possible without providing intermediate annealing

This effect is connected with reduction of pH solution at the surface of this layer due to occurrence of a gradient of concentration of H + ions and protonation of sulfur atoms.
