The tetrahedral are classified using the Q i terminology, where i represents the number of bridging oxygens per tetrahedron.
The number of Alizarin red S positive nodules was more abundant in the experimental group at all times in this study.
The size and number of the nodules increased with increasing cultivation time, and some of the cells were fused together.
Slow heating (1 oC/min) preserved the original configuration with a three-dimensionally interconnected open pore system after firing and the struts of porous skeletal consisted of homogeneous and dense grains.
After the cells were treated with osteogenic supplements, there was a distinct decrease in the number of cells, which is analogous to the number of cells when they were initially incubated .

Experimental results indicated that oxygen content, grain size of SiO2 and oxide layer thickness increased, whereas the tensile strength decreased with rising the heat treatment time.
After oxidizing for 100h, a large number of cracks have formed on the surface, which also originated from the interface.

Mg-Mg2Si in-situ composites by the addition of Si in Mg have become more attractive since the Mg2Si phase impedes the grain boundary sliding at elevated temperature because of its inherent properties which greatly improve the heat and wear resistances.
As the normal load increases, Mg2Si particles at the surface introduce more number of subsurface crack into the system.

Sapphire is aluminum oxide in the purest form with no porosity or grain boundaries, making it theoretically dense.
The number of observed structure factors by the experiment is limited and have some errors in them.
Parameter Value Number of cycles 75 Lagrange parameter (λ) 0.087 Number of electrons/unit cell(F000) 300 RMEM (%) 0.0225 wRMEM (%) 0.0298 Table 3(a).

Parameter Value Number of cycles 290 Lagrange parameter (λ) 0.1944 Number of electrons/unit cell(F000) 312 RMEM (%) 0.0355 wRMEM (%) 0.0281 Table 3(c).

The intensity of the irradiation is then defined as the number of defects created per atomic site and unit time, noted dpa/s, the total dose by the number of displacement per atom, noted dpa.
No voids are observed in spinel, but near grain boundaries, when under the same conditions voids aligned along [0001] direction can be seen in Al2O3 irradiated with neutrons [51].
They obtained an analytical expression for the saturation number density of interstitial dislocation loops CL considering a set of pseudo-chemical rate equations describing changes of the concentrations of defects on both sublattices, number density of loops and the number of interstitials clustered in the loops.
The germination of the amorphous phase can be heterogeneous, on dislocations, grain boundaries or impurities, or homogeneous.
In all cases we must note that the number of systems studied is tremendously small, but for amorphisation.

If the index already include this word segmentation, then the method is to use exist index pointer pointing to a data field which includes this word segmentation’s document number and address.
The basic principles of the above key management is use a small number of keys to protect the large number of keys, except for master key, the other keys are dynamically generated.
When a user can access a specific function, and in this specific function fine-grained access control can be continued.
The following properties are tested: 1) the changes of system performance parameters when the length of a single file changes, 2) the comparison between changes of system performance when the number file with fixed-length changes. 3) The comparison between the time distribution of system performances when the type and length of the document changes. 4) The changes of the number of documents returned by the system and the query time when the number of the querying keywords change and the file size is fixed. 5) The changes of the number of files returned by the system and query time when the size of the index file changes with the keyword infixed. 6) The changes of the recall rate and precision rate, when the number of index documents changes.
Test results show that the test system performance does not vary much with number of files and file sizes, but the compression and encryption of original files increase linearly with the file size and the number of files.

A device made of SMA consists of an extremely large number of grains.
In turn, each grain contains a complex microstructure of austenite and different variants of the martensite.
One solution method is the use of a representative volume element (RVE), which is built up of a sufficiently large number of grains consisting of a single phase.
Such a deformation will occur, if the number of lattice elements, which are in the M+ and M- state, are different.
The number of lattice elements of the individual variants divided by the number of lattice elements of the total specimen, x- and x+ , can be interpreted as the relative phase fractions of the M- and M+ variants.

What is more, number of fine precipitates were found within the α-Al dendrites.
The microsections were grinded and polished, with finishing polishing done on SiC suspension with grain size equal to 0.25μm.

Nanoparticles have a large number of surface atoms compared to the bulk; therefore, the characteristics of surface atoms have more contribution towards their properties.
In the CdSe nanocomposite films, smallest grain size was obtained for Cd:Se :: 2:1 at about 10nm.
They have also found smallest grain size for 2:1:: Cd:Se precursor ratio. 3.2.2.
For Cd:Se 1:1 system, the relative number of Cd atoms may be insufficient for efficient passivation.
The grain size of the crystallite was determined from FWHM of the intense peak corresponding to (002) plane by using Scherrer formula equation.

In recent years, with the rapid development and expansion of city, many villages have been gradually incorporated into city zone and as a result villages in urban district, normally called in-city villages, come into being, which are sarcastically against the grain with all aspects of city zone.
For example, the number of three-storied brick houses increased to 2 times and five-storied brick houses began to come out.
