This angle corresponds to the theoretical angle between the two (111) and (211) planes, as reported in the Grazing Incidence Small Angle X-ray Scattering (GISAXS) measurements of Revenant et al. [6].
The ratio of the height of the pyramid with respect to the base length of the pyramid was close to ~0.1, in agreement with what was found by Revenant et al. [6].

Under certain conditions of extrusion temperature and strain rate Al-Mg-Si alloys produce coarse recrystallized grains at and near the surface.  
Byrol [3] and Røyset et. al. [4] have shown the primary cause of peripheral recrystallization is microchemistry.
The impact of extrusion parameters on coarse grain surface layer in 6xxx-series extrusions was also investigated by Sweet et. al. [5].

Pipes et. al [6] proposed a modification of PSC, called PWG, which assumes an exponential sensitivity of stress when a hole exists.
Recently, Ahmed et al. [10] evaluated the notched strength for hybrid composites with hole defects.
The parameter Kt is the orthotropic strength factor which is a function of the composite mechanical properties by the following expression:           lt l lt t l t G E E E K 2 21  (2) Where, El is the Longitudinal Elastic Modulus; Et is the Transversal Elastic Modulus; vlt is the Longitudinal Poisson Ratio; and Glt is the In-plane Shear Modulus.

Introduction Tomato fruit is a fruit that is rich in vitamin C, vitamin A, beta carotene, lycopene, phytoene enzymes, and phytofluene (Castallana, et al., 2020) (Madia, et al., 2021).
The hydrocolloid group consists of proteins, alginates, and polysaccharides (Mohamed, El-Sakhway, & El-Sakhway, 2020).
The wave number of 1644 cm-1 indicates a stretching vibration of the carbonyl group indicating a water molecule bound to starch(Choi et al., 2022; Zhou et al., 2021a).
The edible film with the addition of red ginger obtained basic stretching of –OH groups at wave numbers 3452-3466 cm-1 (Haghighi et al., 2019; Kumar et al., 2019).
