Both spectra show three bands below 1000 cm-1 attributed to the vibrations that are intrinsic to the (Al-O) tetrahedral sites and (Zn-O) octahedral of the spinel characteristic.
El-Sayed et al. (2002) (14);, when studied the influence of zinc in some properties of Ni-Zn ferrite obtained by the conventional solid oxide absorption bands observed below 1000 cm-1.
The results of this study confirm the results obtained by El-Sayed et al. (2002) [13].

The solid state reaction process between elemental W and C powders during ball milling had been studied in detail by El-Eskandarany et al. [9].
Yamada et al. [15] has made a similar study.
El-Eskandarany et al. [20] ball milled the mixture of WO3＋C＋3Mg for 12 h, they found that most of the WO3 was reduced to W with a small amount of residual WC.

Many researchers have found that the addition of nanoparticles could enhanced the optical and luminescence characteristics as has been reported by Amjad et al., (2014) [9] and Dousti et al., (2013) [10].

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.

Curve 4 shows the photon transmittance through a 1 μm thick Al foil.
Curves 1a, 2a, 3a and 4a show angular distributions of BTR taking absorption in the Al filter into account and are multiplied by factor of 5.
Curves 1a, 2a, 3a and 4a in Fig. 5 show the angular distributions of the BTR after passing through an Al filter having the thickness of 1 μm.
The dash-dot line shows the energy of the L-edge of the radiation absorption for aluminum (EL=72.6 eV).
After the DTR passes through an Al filter, the radiation yield will be suppressed for quanta having energy Eg> EL.
