The results indicate that the model is in good agreement with the experimental data and the dosage of chlorinating agent and roasting temperature play a key role in improving the volatilization ratio.
Numerous methods such as conventional flotation, acid leaching, magnetizing roasting-magnetic separation and direct reduction roasting, etc., have been theoretically and experimentally investigated to recovery or remove the non-ferrous impurities from pyrite cinder [4, 5].

According to X-ray phase analysis data, it was shown that the “Biopur” ceramic support is formed by magnesium aluminosilicates of the composition MgAl2Si3O10 and MgAl2Si4O12.
X-ray powder diffraction data show that the “Biopur ceramic” support is mainly formed by magnesium aluminosilicates of the MgAl2Si3O10 and MgAl2Si4O12 composition and also Al2Si3O10 and to a lesser extent sodium and calcium aluminosilicates of the composition Na2Ca2Si3O9.
The X-ray powder diffraction data indicate the occurrence of these processes (Fig. 2).

Experimental data on the EC of the hybrid NF was obtained using an EC meter at different mixing ratio and temperatures.
The experimental data was divided into three main parts, which were randomly categorized as train, validation, and test sets.
The train set contained 70% of the data points, while the validation and test set each contained 15% of the data points
RMSE= 1ni=1nσactual-σpredicted2 Where n is the data points for the experiments, and σ is the EC ratio.
Fig. 2 and Fig. 3 shows that an augmentation in the mixing ratio led to a reduction in the EC ratio of the hybrid NF.

For combustion pressure, the CH4 chemical composition of the LFG was lowered, which led to the combustion delay and the reduction of combustion pressure Introduction Nowadays, SI engines are used in many areas, including transport, power generation, and industrial sectors.
Therefore, the purpose of this study is to obtain basic research data for increasing the usability of LFG by identifying the combustion characteristics for each LFG chemical composition ratio.
Combustion pressure was measured by the pressure sensor installed in the static combustion chamber and used as experimental data for the research.
The data showed that the maximum combustion pressure results were similar in methane 100%, LFG70, and LFG60.

The method consists in the determination of several sub-profiles obtained by the segmentation of the acquired profile data set .
For the purpose the data are structured in the following matrix:
The data of representative peaks can be used to evaluate MR as a function of working time: it is obtained by subtracting the peak area at a generic working time from the original peak area.
BF presents a behaviour characterized by constant scattering of MR with a progressively reduction of removal speed, except for the first stage.
In this experimental the reduction in heigth has been about 20% corresponding to a 5% section reduction, which is negligible.

These findings lead to a discussion on the potential of indoor air temperature reduction by applying green roof.
Grace Tiberio Cardoso, Francisco Vecchia (2013)[11] Experimental study by installing thermocouples to collect surface temperatures and indoor air, comparing them with existing prototypes in an experimental plot Green roofs applied to warm and dry climates provide an interesting time lag with surface and internal air temperature reduction.
These findings lead to a discussion on the potential of indoor air temperature reduction by applying green roof and cool roof.
The temperature and the relative humidity for both internal and external data were recorded at 30 minutes interval for a period of 6 days using the temperature and humidity data loggers during peak summer days.

Also, reduction of capital and operating costs as a result of the reduction of number of equipment units of the plant [18, 21-23] is another benefit of the process.
The simulator allows a wide range of tasks such as estimating and regressing physical properties, generating custom graphical and tabular output results, fitting plant data to simulation models, optimizing processes, and interfacing results to spreadsheets to be performed.
It offers a lot of benefits which include supporting full range of process industries, continuously improving chemical process designs with Activated Analysis, expanding modelling to include solids, comparing simulation and plant data in real time, extending functionality with layered applications, and using highest fidelity engineering platform [5].
Some published experimental data on phase equilibrium and reaction studies were used to verify the model predictions, and the results were found to be close to each other.
As can be seen from the figure, the process portrayed a uniform reduction in mole fraction when the reboiler duty was less than 1450 W.

Based on field data of sediment and water volume in the Lower Yellow River from 1950 to 2000, the sediment-transport water volume and unit sediment-transport water volume in LYR are calculated.

During each test, strains, displacements and loads were recorded by a computer-controlled data-logging system at intervals of 0.1 second.
By plotting load and deflection data, derived from the column buckling tests, in this form, "best-fit" straight lines may be derived.
The compression force and strain data used were those corresponding to the compression strain range 500 - 2500 micro-strain.
It was also found that Southwell plots of the test data in the form w/F versus w (Eq. 3) and ε/F versus ε (Eq. 4) enabled the buckling loads to be determined.
In Table 2 a comparison is presented of buckling loads obtained from the FE analyses, the load versus end-shortening curves and the Southwell plots of the test data.

Fig. 3 Wing-body-tail configuration Fig. 4 Wing-body aerodynamic axis system Test Models The precursor study revealed that between Mach numbers of 0.3 to 1.3 the longitudinal aerodynamic data or data in the pitch plane showed approximately a 1.3-degree shift in the data between the FDM and metal model for the normal force (Figures 5, 8 and 11) and approximately a 0.8-degree data shift for the pitching moment (Figures 6, 9 and 12).
Except for these shifts, the data trends for each model type were consistent with each other.
The lateral directional aerodynamic data show some small discrepancies between the two model types.
The data do, however, show a slight shift in the data trends between the models.
On average, there is a .004 shift in the side force data trends slope and a .0003 shift in the yawing moment data trends slope between the metal and the FDM model as shown in figures 14, 17, 20 and 15, 18, 21.
