Mechanical strength values of green compacts Review of the obtained data shows that briquette strength properties for any types of binding agents increase gradually as the compacting pressure grows.
Green bond test results of briquettes with different binders When reviewing the data of Fig. 3 it shall be noted that when the organic binder Polyplast 5SV was used the briquettes after dropping and sieving had the minimum sieve residue of fine fraction and the maximum sieve residue of coarse fraction.
Reviewing the given data the briquette drying time of 10 minutes is believed to be sufficient as further increase of this parameter leads to insignificant growth of sample strength values.
Basic coke carbon oxidation periods Period temperature (°С) I II III IV V Start Interval Start Interval Start Interval Start Interval Start Interval 574 47 621 128 749 174 923 65 988 61 In the context of heat emission process development the data related only to the first and second periods are of primary importance for evaluation of the coke carbon oxidation kinetics, as subsequent processes are determined mainly by the gas - coke surface interaction dynamics.

However, it still may not be the best solution because Mild Steel has the lowest value in terms of material recovery impact, which means a reduction in the environmental impact factor.
The results from the proposed method was compared with the Eco-It and the actual experiments.Table 4 shows a summary of the results produced by the Eco-it and the actual experiments for the three designs which have been compared with the data generated by GA.
ID Total Environmental Impact EIAT (kg CO2-eq) Total Environmental Impact Eco-It(kg CO2-eq) EIAT-ECO-It Difference percentage % Data from Actual experiment(kg CO2-eq) EIAT-Actual Experiment Difference percentage % 5051 0.639 0.667 4.35% 0.702 8.97% 8008 0.739 0.801 7.77% 0.797 7.28% 5942 0.919 0.991 7.16% 1.009 8.92% It can be seen that the data produced by EIAT is in good agreement with the Eco-It software and the actual experiments with the percentage difference of less than 9 % in both cases.
Based on the data of the actual experiment, three of these designs were chosen to validate the EAIT against a commercially available eco tool called ECO-it.

Those devices benefit from the high critical electric field of 4H-SiC (up to 2.8 MV/cm [1]), which enables a high breakdown voltage and a reduction of the static conduction losses compared to silicon devices.
The implanted dose is calculated by integration over the data measured by SIMS.
The compensating defect density Nc, the density Na and the ionization energy Eion of electrical activated acceptors were determined using a fit of the charge neutrality equation to the experimental data of p(T) (Eq. 1) [1, 3-6].
The solid lines are fits of the neutrality equation to the measured data in the temperature range from 250 K to 500 K.
The ionization energy is obtained from the slope of the data of ln(τ) in dependence on the reciprocal temperature.

Currently, public and countries worldwide are mutually facing the enforcement of the green-economic era concerning energy saving and carbon reduction.
The term of Intelligent Information Communication Services refers to the activities, facilities, and architecture in which information and communication technology is integrated through electronic control interface, which in turn helps transmit the data of activities and facility operations to the central monitored control system via information technology integration in order to achieve higher level of independent operations for controlling, monitoring, recording, rectifying, and warning on equipment functions.
Data Analysis From the previous description, this study adopts intelligent information communication services as analysis basis, simultaneously uses all messages contained CSR concepts (e.g. unlimited form of website contents on the past history, mission and vision, activity announcement, services, etc.) as observed units in order to assist the proposed CSR definitions to evaluate and analyze collected data.
This study aims to employ the common digital type taxonomy and the random sampling method to collect data from large 500 companies listed in the America Fortune magazine (Esrock and Leichty, 1998, 2000), and then integrates website present type and common mode.

HRTEM data collected from the synthesized ANFC400 material depicts the core-shell type nanostructures are developed representing graphene layers wrapped around alumina nanofibers (ANFs) along a longitudinal axis.
As seen in Fig. 3b, formation of micrographs of the three-dimensional arrays of graphenated alumina nanofibers graphene flakes have been approved on the fibers in agreement to the TEM data.
Each fiber is about 20–30 nm in diameter, aligned along the fiber axis which confirms the SEM data.
Electrochemical measurements depicted multiple steps/stages for charge/discharge curves corresponding to sequential reduction for sulfur to Li2S (16∙Li + S8 ↔ 8∙Li2S) [10].

Recently health food supplements containing usic acid have been promoted for use in weight reduction, with little scientific support.
HMBC and HMQC Correlation of Compound 2 Based interpretation of 1H-NMR, 13C-NMR, NMR-2D, IR, data and by comparing NMR spectrum data of usnic acid [11], the compound (1) was ascertained as usnat acid derivative (molecular structure as shown in Figure 1) which is minus the hydroxyl group on the C-3 atom because there is no aliphatic hydroxyl observed at chemical shift ≥ 17 ppm.
Salina, the compound 2 be considered as moderately toxic considering to the 50% of lethality it caused at the concentration of 19.49 μg/mL, the data calculate showed in Fig. 4 and Table 1.

Therefore the heat loss through the building envelope can be minimized by optimising the shape of the building to achieve reduction in heating demand [4].
The annual heating loads were calculated using recorded climate data.
Local climate data and technical specifications of the building were used as input data for energy performance simulation tool to estimate the energy consumption.
The data on climate conditions of all regions of Kazakhstan are used for the design of all structures and facilities (residential, industrial, etc.).

On the other hand, the growth rate activation energy determined from temperature dependence data of the thermal oxidation in dry or wet oxidation estimates the thickness to be close to 1 Å.
Therefore, the thermal oxidation data suggests that the oxide does not grow on Si at room temperature, in contrast to measured data [11].
Change of PL intensity and thickness of native silicon oxide on RIE and MACE pillars overtime (The data of the first 100 hours are provided in the graph below).
The main reason behind this is because the noble metal acts as a microscopic cathode on which the reduction of the oxidant (H2O2) occurs [26]: H2O2 + 2H+ à 2H2O +2h+ The generated holes are then injected into the Si substrate in contact with the noble metal.
