Research by Khashaba et al. [3] demonstrated that increasing the feed rate leads to greater delamination in glass fiber-reinforced epoxy composites, which weakens the material and reduces the load-bearing capacity of threaded joints.
Research by Ribeiro Filho et al. [7] investigated forming taps versus cutting taps in carbon fiber composites.
The study by Ribeiro Filho et al. [7] demonstrated that increasing cutting speed from 10 to 28 m/min reduced both thrust force (by approximately 25 N) and cutting temperature (by ~18°C), indicating that higher speeds can improve threading efficiency by reducing mechanical and thermal loading.
Freitas et al. [8] showed that bidirectional compensation systems and TiN coatings reduce thrust force and torque, with cutting speeds increased from 5 to 15 m/min reducing thrust force to 60 N.

The numerical investigation of NH4Cl-H2O solidification is a relevant opportunity to validate a volume averaged multiphase model by Ludwig et al. and Wu et al. [4-6].
The growth velocities of equiaxed grains were analytically derived [4-6] as ** * 2 el ll e l R cc cc d D v e − − ⋅= , (1) where lD is the diffusion coefficient, ed is the diameter of the equiaxed grains, *lc and *ec are the equilibrium species mass fractions at the liquid/solid interface.
In contrast to the shadowgraph technique applied by Beckermann et al. [12] the presented PIV setup generated a 2 (mm) wide light sheet that illuminated the cell from the top.
The results showed relatively low solid fraction throughout the settling process which was in agreement with previous work by Beckermann et al. [3].

Sugie et.al. [7] proposed a method for predicting the sound absorption characteristics of fibrous materials like glass wool, covered with a perforated panel and an impermeable film using the method based on Ingard and Bolt’s model (1951).
Hong et.al. [8] studied an acoustic analytical model for a novel composite absorber made with layers of PU and recycled rubber particles.
Ekici et.al. [10] studied the sound absorption property of polyurethane foams loaded with natural tea-leaf fibers and the results show a significant improvement in the sound absorption property when using the natural tea-leaf fibers as a filler material.

Among these, Ekman et al. focused the attention on the probability of occupants’ injuries [18]; Waimer et al. investigated on the structural behaviour of aircrafts under different crash scenarios, focusing the attention on the failures mechanisms [19].
Guida et al. developed a simplified finite element model of a typical composite fuselage able to predict the energy absorption capabilities of the structure during an emergency crash landing [20].
Marulo et al. investigated the design of C-shape stanchions, made of CFRP (Carbon Fibre Reinforced Polymer) material, under both static and dynamic load conditions defining a numerical procedure finalised to the structural optimization of the component [21].

According to Ilham and Utami et al [1] [3], amplification of red rice using RC12 primer would show three band DNA at 100bp, 170bp dan 315bp.
Research from Feller et al [8], showed bHLH is a transcript factor that the expression can be influenced by environmental factors and other transcript factors such as MYB.
In addition, according to Furukwa et al [9], regulation of the rc-bHLH gene which regulates the proanthocyanidin protein in red rice is also influenced by the presence of the rd-bHLH gene.
This result match with the literature from Utami et al [1], the rc-bHLH gene is found on chromosome 7 at positions 6,061,189-6,067,617 bp, in clone AP005098 in the rice genome.

The variation of the [4]Al, [5]Al and [6]Al content with Td is presented and discussed.
The respective atom percentages of [4]Al, [5]Al and [6]Al were quantified to 25, 20 and 55% [5].
The average values of and ΔCS between the three [n]Al sites show the same hierarchy whatever the temperature of deposition: ([4]Al) > ([5]Al) > ([6]Al) and ΔCS([4]Al) > ΔCS([5]Al) > ΔCS([6]Al) [20].
The structure of γ-Al2O3 is made of tetrahedral [4]Al and octahedral [6]Al sites in the atomic ratio [6]Al/[4]Al ≥ 2.

Typical aluminum alloy Al-2024-T3 and Al-7075-T6 were used.
Al-2024-T3 was used for the skin, floors and floor beam structure.
Al-7075-T6 was used for the structure of the bulkheads and stringers.
