The pH of the solution affects the surface properties of the adsorbent as well as dissociation of the adsorbate molecule[[] Ahmed El Nemr, Ola Abdelwahab, Amany El-Sikaily, Azza Khaled: Journal of Hazardous Materials. 161 (2009), p. 102–110. ].The variations in the amount adsorbed of dye from solution at various solution pHs are shown in Fig.1.

Seismic wave is El-Centro wave whose peak acceleration is 600gal.
As you can see from the table 1, in El-Centro wave excitation, the relative displacement of the top and bottom with semi-active control reduced 42.54%.

The Benchmark II model was selected as the model for simulating, and the N-S component of the 1940 El wave was selected as the input load.
Iterative learning control can be traced back to 1978, in which year Uchiyama[5]presented the initial explicit formulation of ILC in Japanese, and Arimoto[6] et al. first introduced this control method in English, in 1984.
Youqing Wang[7] et al. studied and compared three kinds of control methods including ILC,RC and R2R, then the authors pointed out that ILC was a hot filed.
Smolders[8] et al. proposed a nonlinear iterative learning approach based on model.
The Benchmark II model was selected as the model for simulating, and the N-S component of the 1940 El wave was selected as the input load.

Šimor et al. [4], who have used a plasma discharge element manufactured of an alumina plate upon which TiN strips were deposited using the magnetron sputtering method while the induction electrode was made of Molybdenum.
It also agrees with the results of Jozef Ráhel et al. [6] who have used a plasma reactor made of an alumina dielectric plate along with tungsten electrodes.

To solve this problem, H.T.El-Dessouky[4] proposed an evaporative cooling system integrated with hollow fiber membrane module, which would manage to pre-dehumidify the process air in a vacuum environment built by a vacuum pump.

Experimental The milling of SiCp/Al composites were performed on a milling machine center.
The SiCp/Al composites have Vf =45 % SiC reinforcements with an average size of 3um.
The microstructure of SiCp/Al composites used is shown in Fig.1.
Fig.3.b) shows that the percentage of Al, Si and O element is higher than the matrix.

Experimental procedure Experiments were conducted on industrial AZ91 alloy with chemical composition of Al 9.0%, Zn 0.8%, Mn 0.2% wt.%.
Yield point (YP), ultimate tensile strength (UTS) and total elongation (El) were calculated from room temperature tensile tests.
(a) The wheel side surface (b) BSE micrograph of the material with EDS element mapping (Mg, Al, Zn) of magnified area.
This effect can be ascribed to highly dispersed nano-sized Mg17Al12 phases and higher content of Al element in the solution.

Kadirgama et al. [5] studied the cutting tool life and wear mechanism of Hastelloy-C22HS.
Akıncıoğlu et al. [1] studied the role of cryogenic treatment for carbide cutting tools to improve the machinability of Hastelloy-C22.
Therefore, the parameters were taken from previous research studied by Abotula et al. [16]

According to Ghani et al. [7], a reduction in cutting force (i.e. higher cutting speed) leads to the formation of less surface roughness.
· Cavity: According to El-Wardany et al. [14], when the tool wear progressed, surface metal was displaced in the direction opposite to the feed mark ridges.
However, Sharman et al. [15] believed that the formation of surface cavities was associated with carbide particles.
