Ozben et al. [2] studied the machinability of Al/SiCp in turning operation which was produced by casting method by adding 5, 10 and 15 wt% of SiCp.
Kilickap et al. [3], studied tool wear and surface roughness in Al-5% SiCp turning operations with uncoated and TiN-coated carbide tools.

The statistical analysis show that the frequency of dust storms in the most of Northern China are increased during the La Niña, while decreased during the El Niño.
The second SVD mode of Pacific SST is very similar with El Niño.
According the second SVD mode, It is clear that the frequency of dust storms in the majority of Northern China are decreased during the El Niño. 3 Results of dust model system experiments The integrated numerical simulation and forecast system of dust weather is usted to verify the influnence of Pacific SST on the dust storm in China.
(2) According the SVD analysis, the frequency of dust storms in the most of Northern China is increased during the La Niña, on the contrary, the frequency of dust storms in the majority of Northern China is decreased during the El Niño

Zhang et al[10]. reported a WOLED with a maximum luminous efficiency of 9.22 cd/A and a maximum brightness of 8633 cd/m2 by using phosphor sensitized fluorescence.
Finally, a LiF buffer layer and Al cathode were vapor-deposited at a background pressure of 4×10- 4Pa onto the organic films.
Normalized EL spectra of WOLEDs with structures of ITO/NPB(30 nm)/CBP: 10% DPVBi (10 nm)/CBP (5 nm)/CBP:x% Ir(ppy)3 : y% rubrene (20 nm)/ CBP (5 nm)/CBP: 10% DPVBi (10 nm)/BCP(10 nm)/Alq(30 nm)/LiF(0.5 nm)/Al.
The device has the maximum brightness of 31770 cd/m2 and the maximum EL efficiency of 11.63 cd/A.
Inset: Normalized EL spectrum of the device In summary, we have fabricated a WOLED based on phosphor sensitized fluorescence utilizing an efficient structure.

Dynamic loading was tried using the dynamic loading facility and model waves modified artificially from the famous earthquakes, so called El Centro and Taft, as shown in fig. 11 and 12.
As shown in fig. 12, “El Centro 2” is an instance of an artificial input wave modified from a real El Centro wave.
A turn of artificial earthquakes is determined as a set of Taft level 1, Taft level 2, El Centro level 1 and El Centro level 2.

Eurycomanone as one of the quassinoids has the highest concentration among bioactive components of EL roots, thus more commonly used as the marker compound for the EL roots [7].
Thus, it can be concluded that 90 minutes duration is the ideal extraction time for EL.
Ma, et al. [12].
Three different size of EL roots sample had been studied which are 300, 500 and 700 μm.
Summary The processing parameters affect the extraction yield of EL roots using conventional thermal heating technique were the sample size, time and temperature of extraction and mass ratio of EL sample to the solvent used.
