To improve the comprehensive properties, different alloy systems have been investigated for the development of Mg alloys, i.e, Mg-Zn, Mg-Al and Mg-Mn alloys [5-7].
Paliwal and Jung [16, 17] studied the microstructure evolution of Mg-Zn and Mg-Al alloys using experimental and simulation methods.

Tang et al. (3) have reported low light affected alkaloids contents in the leaves of C. roseus seedling, but the expression of these genes (Tdc, Str, D4h and Dat) under low light in C. roseus seedlings are little reported.
HPLC analysis of alkaloids contents (VIN, CAT and VBL)were performed according to Luo et al (5).

As reported by Ding et al.,2018 [6], the higher calcination temperature could make the pore collapsed, the sintering of particles and blockage of smaller pores, which led to the surface area declined, the pore volume decreased, and the pore diameter increased.
It can be clearly seen that the spectrum shows well defined peaks for carbon (C), alumina (Al), oxygen (O), cobalt (Co) and iron (Fe) as shown in Fig. 1.
This result is in agreement with Houda et al (2018) [7], who claimed that DMF as good extraction solvent for sulfur removal.
Besides, Mokhtar et al., (2014) [8] found that the higher amount of DMF provide higher extracting ability due to the increase of the contact between extraction solvent and sulfur compound in diesel.

A great variety of transition metals have been used as doping elements, as Mn [2], Cu [1-5], Ag [6], Al [6], Co[7], Ni [8], Ti [9] and V [10].
Similar results were presented by Tarwal et al. [11].
Tarwal et al. [11] observed similar optical behavior of Cu-doped ZnO films, despite the precursor salt used (copper acetate) being different from the used in the present work (copper chloride).

The experimental measurement of tensile strength on individual chemical components of cement paste was for the first time performed by Němeček et al. [1] on micro-beams with triangular cross sections created by Focused Ion Beam technology (FIB).
These values were compared to Němeček et al. [1], where the mean tensile strength for inner product was found ca. 700 MPa which gives a good agreement.
Molecular dynamics models using bottom-up approach estimated fracture energy as 1.72 ± 0.29 J/m2 in Bauchy el al. [10].
Němeček et al. [1] found previously supremum fracture energy of the inner product as 19.7 ± 3.8 J/m2 which give a good agreement with the current results.

Further investigation made by Kamoji et.al [5] on two bucket helical Savonius rotor with and without shaft with a bucket twist angle of 90° at different overlap ratios of 0.0, 0.1 and 0.16 and compared their results with conventional Savonius rotor.
Damak et.al [6] conducted experiments on two bucket helical Savonius rotor at bucket twist angle of 180° and compared their results with conventional Savonius rotors particularly in terms of overlap ratios and Reynolds number.
Later on Deb et.al [10] studied the performance of helical roror at 10° twist angle.
Accordingly, it is observed from the result that for all overlap conditions the same trend persist i.e. both power and torque coefficient of the rotor increases with the increase in tip speed ratio up to a certain limit which is also reported by Kamoji et al. [5].

Anderson et al. [1] showed the reduction in cutting force is 25% and increment of tool life between 200 to 300%.
Otherwise, Shi et al. [2] reported the plastic deformation of Inconel 718 materials was reduced due to the reduction of cutting force when the preheat temperature rise between 700 to 800 oC.
Navas el al. [3] shows that the optimum distance of 45 mm between laser spot and cutting tool in turning process has achieved the maximum reduction of cutting force and minimum tool degradation by applied overheating.
Furthermore, Dumitrescu et al. [4] revealed that the appropriate distance for AISI D2 material is 85 mm in laser assisted turning process.
