For the stress-strain behavior of unconfined and confined concrete, the model proposed by Mander et al. [14] was used for the specimens X0-REF1, X26-REF2 and X26-M.
The lateral load capacity of the specimen X43-M-CFRP2 was calculated by using FRP confined concrete behavior (compressive strength and corresponding strain) as described by Ilki et al. [15].

Burland et al [2] proposed the concept of settlement reducing pile foundation in 1997, and many scholars have made further research theoretically.
In test study, Chi et al [6] conducted two tests of composite foundation with 9 piles in order to investigate the working mechanism of composite foundation with rigid piles.

Sakai and Jonas [2] reproduced a plot by Sakui et al. [3] where the relationship between the dynamically recrystallized grain size, Drex, and the Zener-Hollomon parameter, ( )RTQZ expε&= , appeared for a 0.16% C steel.
The plot by Sakui et al. also presented the relationship between the initial grain size, D0, and the critical Zener-Hollomon value, Zc, which divides single peak from multiple peak DRX.

Reimann et al. [15] concluded that this effect is difficult to separate from the soil pH in Norway, as the distance from the coast and difference in soil pH occur together.

According to Astika et. al., kapok cellulose can be converted to nitrocellulose for propellant application as long as cellulose purities are more than 90% [4].
Gismatulina et. al. had successfully converted bacterial cellulose to nitrocellulose and it was suitable to be used for manufacture of film and nail polish since nitrocellulose produced was below the 12.5% nitrogen content [1].
All samples were characterized based on the following analysis: Elemental analysis was performed by CHN elemental analyzer (Vario EL III, Elementar, Hanau, Germany) to determine nitrogen content (%N) in nitrocellulose.

However, Amblard et al. [10] have already pointed out that pH variations and the cathodic hydrogen co-deposition also determine the growth mode and the texture of electrodeposits.
According to Amblard et al. [10], the observed texture is a result of the plating conditions and of processes that occur in the cathodic layer.
