For this composite, the large increase in the loss tangent as a function of the frequency shows the existence of a strong interfacial polarisation phenomenon, clearly indicating that CNT/PDMS composites are percolative systems with a critical weight fraction between 1.0 and 2.0 wt.% of CNT.
Although N-rich phases are not present in the XRD spectra, the increased resistivity of TaN films as a function of the nitrogen ratio indicates the existence of N-rich phase in Fig. 3.
There were philosophers then, as there probably always will be, who wanted to argue that the intellect was a function of the soul, having no existence outside of the soul.
The experiments performed on irradiated cells by Geva-Zatorsky et al. showed the existence of two frequencies of p53 oscillations as a function of the irradiation dose but the co-existence between these two types of oscillations for the same irradiation dose has not been firmly observed experimentally so far [11].
As previously demonstrated [19], we reported the predicted anti-correlation at short time for spatial separations larger than the beam waist, the expected decrease of the overall amount of correlation as a function of distance and the existence of a maximum of correlation at a distance corresponding to the average time necessary to reach that location.
Data obtained for the proton relaxation time as a function of temperature show the existence of a transition for each grafting ratio used.
We also subdivided the whole population into two groups in function of the existence of altered LVEF at baseline, defined by a threshold value of 45%.
The latter is modelled as a function representing the existence of two different metabolic modes, namely the respirative mode and the respiro-fermentative mode, as well as modulation factors taking account of inhibiting metabolites.
This instrumental view of the world, in which value is a function of market price, threatens the existence of the humanities and thus our culture.
