The sources of inaccuracy and the speed-dependency in the existing defect size estimation algorithms are explained.
We notice that for graphite the existing defect is not major and did not influence the resulting defects in exfoliated graphene.
The patient served as his own bioreactor as the exogenously prepared customized mandible replacement was grown inside his latissimus dorsi muscle prior to transplantation to repair the existing defect.
Crack growth and fracture predictions are used in high temperature equipment operating in the creep and creep/fatigue range by assessing crack initiation and growth from an existing defect.
It is shown that existing defect size estimation methods include assumptions that describe the path of the rolling elements in the defect zone leading to poor estimates of defect size.

The analysis of Raman spectra also gave the evidences of the existing defects in CNTs.
It is based on the selective masking of existing defects revealed at the surface of the substrates by Pt nanoparticles.
The substructure at an early stage of shear banding was found to strongly depend upon existing defects, especially deformation twin patterns.
In the present case, the interstitial incorporation of nitrogen atoms in place of oxygen vacancies (VO) [11],[13] diminish the existing defects states due to passivation, and leads the density of carriers to lower values.
