The isothermal data conform to the Langmuir model with the maximum adsorption capacity of 714 mg/g at 298 K.
According to the negative values of Gibbs free energy change (ΔG°) and enthalpy change (ΔH°), reduction of Langmuir adsorption coefficient with the increase of temperature, the adsorption system from 298 K to 328 K is confirmed to be of spontaneous and exothermic nature.
Fig. 3 Effect of time and temperature on sorption Fig. 4 The molecular structure of Congo Red To better understand the mechanism of the adsorption process of CR onto La/MFA, pseudo-first-order and pseudo-second-order kinetic models were widely used to analyze the experimental kinetic data.

According to the comparison of the correlation coefficients from two models, the equilibrium data follow the Langmuir model well (R2>0.999), but the fitting result for the Freundlich model is not ideal.

In general, data exchanged on an industrial network can be classified into two groups: realtime and non-realtime data.
Non-real-time data do not have stringent time limits on their communication delays experienced during the data exchange.
In general, data exchanged on an industrial network can be classified into two groups: real-time and non-real-time data.
This real-time data can be further divided into periodic and asynchronous data, depending on the periodic nature of the data generation.
For example, the data for program download belong to non-real-time data, while digital control command and alarm signal are periodic and asynchronous real-time data, respectively.

The emphasis of the paper is placed on effects of noise-corrupted recorded data on the reliability of the IDDM method.
This assures that similar wind velocities have a very small return period and, hence, allow to collect large sets of data in terms of structural responses to perform damage detection analyses.
As Figures 5 and 6 point out, at the increase of the noise level the accuracy and the reliability of the procedure deteriorates, even using responses coming from longer data recordings.
Simulations of recorded data have been corrupted with noise.

This process can take place due to chemical reactions in the electro and electrolytes, both reduction and oxidation reactions.
(a) (b) Figure 4 (a) Tensile testing tool (ITNY engineering materials laboratory), (b) Vickers hardness testing tool (ITDA material test laboratory) Results and Discussion In this section, the results of data processing are displayed on the results of the tests that have been carried out.
The data from this study were sourced from tensile and hardness tests using 6 specimens.
For the analysis of the tensile test, the data is taken from the average value of each variable used. 1.
Conclusion From the results of the research that has been carried out, starting from the manufacture of specimens to data collection and data processing, the authors can conclude that the tensile strength has different variations in coating time for the highest results obtained with a coating time of 60 minutes, namely 546,155 Mpa the longer the coating time, the stronger the results obtained.

Fig. 4 shows, that the geometry of the chip in the simulation has a relative difference with the experimental data, due to the sensitivity of the dynamic curvature of the chip to the parameters of the grid (the quantity of cells and thickening of the grid area).
Based on the simulation data, we can conclude that the most appropriate criterion for fracture in the simulation of the cutting process is the criterion of maximum allowable stress.
For adequate result data clarification of rheological properties of the material being processed is required. 3.
Geometry of the chips in the FEM - simulation has a contrast to the experimental data, due to the sensitivity of the size of elements of FEM-mesh (size of the cells and thickening of the grid area) to varying curvature of the chip during cutting; 3.
For a more adequate result data clarification is required on the rheological properties of the material being processed.

In this respect, data related to the effect of SFA and SFE on probiotic bacteria could bring new insights in the development of chemo- and radiopreventive diets.
Data are means ± SD from 3 replicates.
The MRS-grown culture did not exhibit any QR activity in the sets with irradiated or non-irradiated cells (data not shown).
Data are means ± SD from 3 replicates.
These data are new evidence on the role of SFA and SFE in inducing detoxification enzymes (e.g., QR) also for lactobacilli.

The variation of the logarithm of the current density was plotted as a function of the overpotential using the data obtained from the linear voltammetry at 1mV/s.
In the cathodic region the reaction is similar for all four metals: reduction of the solvent.
The following assumptions were made based on thermochemical data (most stable species for each metal in LiFNaF): for Ni, Mo and Fe, n=2 and for W, n=4.
The Tafel methods and the polarization resistance method are interpretation of two different sets of data hence the discrepancy between the methods.
For the last named parameter there is a general lack of data and complementary experiments are needed in order to determine free oxide concentration and evaluate its impacts on corrosion rates.

Meteorological data, measured by automatic weather observation installation in the north of the experimental area, included temperature, humidity, precipitation, sunshine duration, wind speed, radiation intensity, etc.
Rice from each pot was harvested and threshed individually and yield was calculated also, all of the data were also shown in table 1.
Results and discussion Effects of soil moisture potential control on rice yield The species and yield data were shown in Table 1.
Production data shows that moisture control in every growth period is able to increased rice yield, and the yield of each treatment reduce with the increase of drought level except treatments in Milk maturity stage.
The impact of water stress on dry matter The roots, stems, leaves and ears of each treatment were separated after harvest, then their dry matters were weighed and the data were shown in Table 1.

As compared the life cycle of the fast changing product, the reduction of design processes gets tremendous attention from not only PC designers but LCD makers.
The analysis results were compared with test data given by Samsung Electronics.
The main function follows: (1) to generate automatically finite element model with CAD data, (2) to perform impact simulation by connecting LS-DYNA3D, and (3) to process automatically the analysis results.
User can read the CAD data and generate finite element model using the re-meshing module.
The input file for LD-DYNA3D is made up of material and boundary data being input at relevant modules, as well as element data.
