In this study the grain sizes that are used are of the order of 1 nm to 6 nm [8] which is considerably smaller than that of raw particles, assumed to be agglomerated, usually between 1 µm to 50 µm [5], [9], [10].
Molecular dynamics (MD) technique has been applied in a number of experiments on particle impacts to a substrate [11]–[13].
It has been applied in the study of, for example, defect formation and migration, fracture, grain boundaries, structural transformations, radiation damage, elastic and plastic mechanical properties, friction, shock waves, molecular crystals and epitaxial growth [11], [15].
Experimental Design - Molecular Dynamics Simulation There are a number of experimental conditions that can be considered in the CGDS process such as the particle size, incident velocity and angle to the substrate, temperature of the substrate, etc.
The maximum numbers of atoms used in the particle and in the substrate are about 2013 and 60760, respectively.

In fact, the active cutting edge density (the number of active cutting edges involved in grinding per unit area in the wheel surface), which is the dynamic cutting edge density, is higher than static cutting edge density [5].
There is ample opportunity for the number of cutting edges to increase due to local deflections of the wheel and of the grains.
A 10× objective lens with measurement sampling of 1.65µm was used when measuring with the Wyko RST, which enables values of cutting edge density to be obtained rather than grain density.
The number of active cutting edges in the same area, were counted by observation of the wear flats.

This is because if the number of phases in the flux is equal to the number of components in the slag system, there is only one degree of freedom, and for a particular temperature there are zero degrees of freedom; the activities of FeO and P2O5 are fixed and therefore independent of the bulk slag composition.
Suito et al. [14-16] measured the distributions between CaO grains, 2CaO·SiO2 grains and CaO-SiO2-FexO slag with five equilibrating methods.
Phosphate capacity of nine slags numbered A through I whose compositions are shown in Figure 3 was calculated by means of the FactSageTM thermodynamic software.

The test results show that the main factors influencing the mechanical characters of geotechnical materials include its type and property, confining pressure, number of cycles, static deviator stress, dynamic stress, vibration frequency, drainage condition, etc.
And then, a number of empirical models have been proposed by considering one or several influencing factors, these models are used to predict cumulative deformation of some geotechnical materials like soft clay, silt, sand, grained soil, and so on.
Among these, the representative model was built by Monismith(1975), which is an exponential model for cumulative plastic deformation of clay under cyclic loading (1) Where, is cumulative plastic strain; is number of cycles; , are fitting parameters.
Cumulative plastic deformation for fine-grained subgrade soils.

In the conclusion of the review of existing methods for processing of carbide waste, it is necessary to describe the shortcomings inherent in these methods: • A large number of stages (all chemical methods) • Poor performance • Partial or total loss of cobalt during processing • Isolation of large amounts of harmful chemical compounds and work with hazardous reagents (chemical methods) • Heavy equipment wear (mechanical grinding) • Iron powder (mechanical grinding) • Difficulty in implementation for small industries due to the need for a large number of different equipment (chemical methods) • Inability to obtain powder of equal or similar in chemical composition to recyclable carbide waste (chemical methods) The method of electro-erosive dispersion is devoid of the shortcomings described above and has great prospects, especially for enterprises that seek to get a full production cycle in one place, including the processing of defective products.
The above installation, despite a number of drawbacks, allowed for electro-erosion dispersion of pieces of bulk material.
Studies show that particles obtained by electroerosion dispersion usually have a subdendritic or highly dispersed dendritic structure with a high density of grains consisting of an oversaturated solid solution of elements and metastable phases.
Setting up the installation and electrolyte selection plays a crucial role in the final grain size.[1] Product Comparison The author [1] obtained a press powder (40% of regenerated VK8 + 60% of ordinary VK8 powder) according to standard technology - kneading with a plasticizer, cold pressing and sintering.

Figure 3 shows the relationship between the number of preconditioning cuts and the horizontal chipping width.
The abrasive grain appeared to even out uniformly on the blade surface.
Dicing blades of the same series have similar abrasive grains, but the surface conditions are not the same.

Although the total number of experimental samples was small (the 23 µm sample was excluded due to the limitation of the heat adhesive and polishing machine), we could polish samples to 40.4 and 58.8 µm when aiming for target values of 40 and 60 µm, respectively.

Based on Service Oriented Architecture, the digital library platform allows the serving of coarse-grained services through the aggregation of fine-grained services offered by the different libraries.
Grid technology can make a processing and analysis for information and data in digital library service, which provides scientific foundation and decision for the library information service from a large number of valuable internet information and documents.
When better serving people, it is important to take into consideration the growing number of available digital libraries, the necessity to adopt advanced information technology in the digital library service.
Still, there are a number of issues on technology implementation waiting for further research including research methodology, information security, privacy, etc.

The large number of binders to be tested led to choosing toxic elements representative of the main groups of toxic elements: cations-forming Cd, Ni (true “heavy metals”), Pb and Zn (amphoteric heavy metals) and anions-forming metals and metalloids (Cr, V, As).
Collaterally, the same number of test bodies was prepared for determination of the contents of studied elements in dry matter by ICP-OES and for determination of toxic elements leachability by the batch method.

The coarse sample appeared to be eutectic cell grains or boundary, and the finer flake-like eutectic is inside the cell.
In addition, decreases in eutectic size caused the number of eutectic cells that appeared to increase.
In addition, it was noted that number of particles formed increased with the amount of additive Ce, and the amount of 0.8wt% resulted in the highest number of particles nucleated, from 12 in base composite to 45 particles per unit mm2.
Theoretically, eutectic cells act as eutectic grains, and more cells with smaller size result in more eutectic boundaries.
