Yusoff et al. [4] investigated laser processing of popular wood in Malaysia.
Hernandez et al. [5] were interested to study Statistical analysis of Ytterbium-doped fibre laser cutting of dry pine wood.
Lum et al. [3] claimed that, the average kerf width obtained for medium-density fireboard reduced with increasing cutting speed for most material thickness.
As claimed by Hernandez et al. [14], an increase in the kerf width area, therefore as increase in the volume of the removed material, was obtained when high powers and lower velocities were applied.

According to Ramirez et al., the object achieved was to find the rate of fatigue crack growth in two standard rail steel specimens [18].
Zhao et al. used FEM with LS-DYNA to discover the SIFs of head cracks under three dimensional analysis approach [19].
Masoudi et al. utilized a fracture analysis software Franc-3D to investigate the SIFs estimation under rolling contact fatigue fracture [20].
According to Yang Liu at el. [27], rail weld crack growth and behaviour of transverse surface cracks in rail and its AT weld subjected to in and out of the plane loading was explored.

Mahanthesh et.al [2, 3] used a traditional model, where the properties of the nanofluids are directly included.
More reasons are provided by Myers et al. [6], to explain these discrepancies.
Mahdi et al. [7] reviewed the convection heat transfer in porous media with nanofluids.
Chandrasekar et al. [8], Kumar et al. [9] assumed in their works that the dispersed thermal diffusivity is important.

From the point of view of the analysis of the authors who publish most cited papers (Fig. 4), the results show how the most cited paper on the topic was published in 2018 from Huang et al. on Resources, Conservation and Recycling [36] with 158 citations, followed by Gàlves-Martos et al. [37] with 154.
In this regard, Aslam et al. [41] defined the interaction between stakeholders as a key suggestion for improving CDW management; · to define integrative strategies to minimize waste.
In particular Ruiz et al. [17], highlighted the need to identify strategies in reference to each of the five lifecycle stages of construction and demolition activities.
