In the paper the main results of numerical study presented in Gambarelli et al. [1] on concrete elements confined by carbon fiber reinforced polymer (CFRP), are overviewed.
Most of the analysis oriented models are derived from the stress-strain relationship proposed by Popovics [13,14] and reformulated by Mander et al. [15].
By means of DP potential function the model proposed by Rousakis et al. [18] was reviewed by Yu et al. [21], which proposed a modified DP type of plasticity model in order to correctly predict the behaviour of both actively confined and FRP confined concrete.
These data, such as the majority of the experimental tests available in the literature (Nisticò et al. 2014) [22] refer to plain concrete.

Based on the spectrum, the band at 463 cm-1 is attributed to T-O (T = Al or Si) bending vibration [9].
In addition, the shifting of the band to lower wavenumbers is also due to weaker Al-O bonds than Si-O bonds [12].
Previous research by Liu et al. [17] on fly ash as alkali-activated binder also detected this peak [17].
Furthermore, the shift to a lower wavelength is due to the polycondensation process of Si-O and Al-O bonds in the alkaline environment during depolymerization of the amorphous phase of fly ash to Si-O and Al-O bonds, which consequently causes decrement in intensity [15].

The water retention value (WRV) of fibers was measured as described by Rom et al [17]. 0.5g oven dried pulp was disintegrated, put into a 200 ml Erlenmeyer flask and suspended in 100 ml distilled water.
According to Rom et al [22], the hydrophobic nature of treated fibres should result in the lower WRV.

Yan et. al [10] found that an Cu-32Zn alloy with 20% deformation showed the domination of slip mechanism.
On the other hand, Duggan et. al [11] described that Cu-30Zn with 60% deformation already showed shear band mechanism.

The pure silica sand grains from both samples showed a similar composition with regards to Si, O, and Al.
However, the white particles found only in the Biala Góra sample contained a high amount of Ti and O, along with smaller quantities of Fe, Al, Mn, and Si (Figure 3b).

In 1977, Wodzinki et al. isolated a naphthalene degradation strain Pseudomonas sp., but the growth of this strain required additional organic solvent [13].
In 1995, Gamerdinger et al. used the Coryneform bacterium to purify the soil that contaminated by naphthalene [14] and Abe et al isolated three naphthalene-tolerant bacterial strains that can degrade naphthalene in the presence of suitable organic solvents[15].
Because of the growth rate of cell that cultured in biphase system was much higher than that cultured in monophase system, and the cell growth stationary phase was prolonged effectively in biphase system, so the cell growth capability was improved, the growth period was shorten effectively and got to the objective of enrichment the cells of LHJ38 by using biphase system technology. 0 0.5 1 1.5 2 2.5 0 12 24 36 48 60 72 84 96 108 120 132 144 Time(h) Na ph th el en e co nce nt ra ti on ( g/ L) 0 0.5 1 1.5 2 2.5 3 3.5 0 12 24 36 48 60 72 Time(h) C e l l c o n c e n t r a t i o n ( g / L ) As shown in Fig3., the degradation rate of naphthalene is more than 92% after 96h, and 2g/L naphthalene can be completely degradated by further reaction in the biphase system, while the degradation process has terminated in monophase system.
