When pressure was up to 2.94 ~ 9.8MPa or more, the stable glass can be damaged violently in short term, and a large number of SiO2 was released into the solution at the same time.
The density was 2.49 g/cm3, specific surface area 4215 cm2/g, grain diameter less than 100μm and the medium particle size 12.1μm.

Introduction Degradation and the associated rehabilitation of building structures of sewerage systems is a current problem, which is addressed by a large number of studies and manufacturers of building materials.
Fine-grained additives (microsilica, micronized limestone, stone fillers) are usually used as additives to improve the adhesion properties and increase the density of the cement composite.
These are a number of biological, physical, or chemical processes with microscopic and macroscopic manifestations.
This was due to the application in pilot plant conditions, and a more significant number of factors probably had an effect on the degree of inhomogeneity.
Before starting the chemical loading itself, measuring pegs were mounted on the required number of test specimens (10x40x160mm) (Fig. 3).

Introduction This paper proposes methods to reduce the number of main defects found in the casting of the type of gearbox housing part.
For having o good productivity a MMF below 17.6% commitment and 14.1% monthly target respectively, represented in Fig. 7, where 349-405 represent the batch number of the worked day.
It is found that shell temperature should be in the range 180°-260°C in order to decrease the number of scraps with 10%.
To significantly reduce the number of rejected the required casting speed should be respected: the optimal casting speed in Phase I of 0.22 m/s gear, optimal casting speed in Phase II of 3.35 m/s, and multiplication pressure of 912 bar.

Using design of experiments, number of runs are decided and the regression models are identified to predict the optimal microstructural zones and its widths along the fusion zone.
The range of welding conditions were decided based on the large number of experimental trails.
Design of experiments (DOE) was used which is a selected as a right approach to decide the number of tests and helps to determine the effect of each parameter and develops the relationships between input and output conditions.
Response surface methodology (RSM) is one of the easiest method among the DOE techniques, with this the minimum number of experimental trails can be decided with the approximate values of the known input process parameters.
The size of the grain increasing from fusion zone to towards the base metal.

This disaster will bring huge economic loss and even kill large number of people and destroy the whole mine.
And the most serious country is China, in this country, all parameters of coal-gas outburst, such as total number and average strength, are the most serious, and the total number of China is approximately one-third of the world [5-7].
Due to high rigidity, close-grained, and low permeability, inner gas is difficult to emit out before the crack of hard coal, and this result to high gas pressure.
But the break of hard coal generates large number of paths and let inner high pressure run out.

It is silicon killed but has fine grain and improved notch toughness.

DUV ozone treatment, where two wavelengths of 185 nm and 254 nm are employed, is an effective technique that could concurrently decrease the amount of defect sites related to oxygen vacancies and increase the number of metal oxide (M–O) bonds [16].
While the surface of STO thin films that have been subjected to the UV-photoactivation or conventional annealing at 300oC have the shape of hills and valleys, with bigger grains as illustrated in Fig.1 (e) and (f), respectively.
However, DUV photoactivation reduced the numbers of defect sites down to 25%.
Oluwabi et.al. [16] reported that DUV activation enhances the quality of their ZrO films by increasing the number of M–O bonds and decreasing the number of oxygen vacancies.

The diffraction peaks found at 37.34˚, 43.38˚and 63.02˚ (2θ) can be indexed according to the JCPDS number (01-073-1519) of cubic NiO structures.
In addition, the agglomeration of silica particles increases due to the reduction in pore size and the decreasing number of pores.
This is well supported by the morphology of sintered forms as shown in Figure 4 where a higher number of open pores were observed at lower temperature.
As the sintering temperature increases, the number of open pores decreases thereby leading to a decrease in porosity.

Because of these conflicting objectives, it gives way for a number of optimal solutions to be generated, generally called as Pareto-optimal solutions.
In recent years, a number of multi-objective evolutionary algorithms (MOEAs) have been formulated and applied because of their ability to find multiple Pareto-optimal solutions in one single simulation run.
They have described cellular GA as a fine grained model of parallel GA implementation which derives from a cellular-automata-like computation.
The following are the values of the parameters of NSGA-II algorithm used in this study: Variable type = Real variable, Population size = 50, Crossover probability = 0.8, Real-parameter mutation probability = 0.01, Real-parameter SBX parameter = 10, Real-parameter mutation parameter = 100, Total number of generations = 100.
The algorithm performs better in our problem since the number of design variables is minimum and also the ability of scalar operator of SBX crossover to create new generations.

It can be seen that the microstructure of the annealed strip consist of equiaxed grains with annealing twins, whereas the cold rolled strip contains number of deformation bands which form network in few regions.
Fig. 3 Bright field image and corresponding diffraction pattern of solution treated sample In order to generate a large number of electron diffraction patterns corresponding to various electron beam directions the double tilt specimen stage of TEM was used.
Bright field image and corresponding diffraction pattern of solution treated sample In order to generate a large number of electron diffraction patterns corresponding to various electron beam directions the double tilt specimen stage of TEM was used.
So, if the thick dimension of the plate (i.e. the habit plane) is parallel to the electron beam (and the thin dimension is therefore perpendicular to it), streaks will be recorded on the Bright field image and corresponding diffraction pattern of solution treated sample In order to generate a large number of electron diffraction patterns corresponding to various electron beam directions the double tilt specimen stage of TEM was used.
