High strength aluminum alloys
Al-Cu-Si-Mn (2014) and Al-Si-Mg-Mn (6082) wrought aluminum alloys have been the principle materials used for aerospace applications, by limiting the content of accompanying elements, especially iron and silicon and by optimization of the manufacturing process, the damage-tolerant variants 2X24 and 7X75 were established; Al-Cu-Mg (2024) and Al-Zn-Mg-Cu (7075) [15].

A large body of research has been devoted to the design and fabrication of cooling channels, found in the recent review studies of Feng et al. [8] and Kanbur et al. [9].
Marin et al. [17] designed parallel and series patterns for CCCs of the injection-moulded component.
Lu et al. [18] also compared the effect of conventional baffle channels and CCCs on cooling time and residual stress.

This statement was agreed by Guo et al. [19] stated that the addition of Fe2O3 causes changes in the unit cell volume and leads to the formation of cubic and tetragonal phases in 8YSZ.
Guo et al. [19] had discussed thoroughly on the substitutional and interstitial of Fe2O3 doped YSZ in their previous studies.
In another study, Barbashov et al. [24] mentioned that 2 mol% of Fe2O3 was doped to 6-12 mol% of YSZ and results showed that 10YSZ had the maximum conductivity corresponding to the minimal volume of crystal lattice.
In a case conducted by Wilhelm et al. and Wang et al., it was proposed that the solubility limit of Fe in 8YSZ was 8.06 mol% and 14 mol% to 16 mol% respectively[36], which suggests there were no peaks detected in the secondary phase of Fe oxides in both cases.

Introduction
Peatland fire in Indonesia has peaked happened in 2015 during a long drought season of El-Nino period.
The basic material of rubber composite was produced referred to Kinasih et al.[16].
Khaloo et al. [23] reported that dam structures become more brittle as their size increases.
Fu et al. [25] stated that the composite strength was really related to the interaction between matrix and filler.
This data showed linearly agreed with Sundari et al. [8] and Cao et al.[9] research result that CO2 emission increased as lowering ground water level.

Fernandes et al. [12] studied the effect of PCMs on the thermal cracking of cement mortar.
Richardson et al. and Lecompte et al. [6,14] have also asserted that PCMs have no contribution to mortar materials' mechanical properties and can be considered pores in the hardened matrix.
The binder material was composed of Portland cement (CEM I 42.5N) is produced by EL-Suez Cement Company, Egypt.

Soluble sugar was measured in shoots and roots according to the method described by Marschner et al. [18].
Na+ and K+ in shoots and roots were measured separately as described by Song et al. [19].
In the present study, the enhancement of NO3- uptake induced by the elevated NO3--N supply also contributed to Cl- reduction, which agrees with Abdolzadeh et al., Gimeno et al., and Song et al. [39, 40, 41]and which might be caused by the competitive absorption of NO3- vs.
