A qualitative study by Nete et al [4] carried out on the three different pegmatites originating from Mozambique revealed that the samples exhibited different degrees of radioactivity and ferromagnetism.
El-Hussaini and Mahdy [7] reported acid leaching of tantalite minerals collected from Kab Amiri using H2SO4 at different temperatures and acid concentrations.
The minerals’ characterization as studied by Nete et al [4], revealed only the physical properties of the samples.
A recent study by Nete et al [12] has investigated the influence of other experimental factors such as temperature and sulphuric acid concentration.

The crystalline phases were augite (Ca(Mg, Fe, Al)(Si, Al)2O6) anortite (CaAl2Si2O8), albite (NaAlSi3O8), magnesium ferrite (MgFe2O4), maghemite (Fe2O3), magnetite (Fe3O4) and wollastonite (CaO·SiO2).
The microstructure of this new type of glass matrices and phosphate glass ceramics have been analyzed by SEM and TEM-EDS, and diffraction type ESBD recently by González-Oliver, Rincón et al. [35] [36].

Takeuchi et al. calculated effects on InGaN/GaN QWs of such orientations [7].
These planes were called semipolar planes by Baker et al. upon their success of planar film growth [8].
An example of XRD scan results is shown in Fig. 19 where satellite peaks have been labeled in accordance with the EL wavelength of the device.
The peak at ω = 18.0° corresponded to the EL wavelength in the present case in terms of In composition.
Satellite peaks have been labeled in accordance with EL wavelengths of the LED.

The genetic algorithm has been used to optimize the shape of the patch by Brighenti et al. [29].
It has been reported by Mhamdia et al. [30] that the arrow shape patch can contribute at the same time to reduce the adhesive shear stresses and the stress intensity factor at the crack tip of the structure.
By making a comparison between single sided and double-sided composite patches in the case of circular shape, Albedah et al. [31] have found that the technique of double patch has better repair performance than that of the single sided.
