Numerous restoration techniques for endodontically treated teeth have been advocated with criteria for success dependent upon variations in length, diameter, shape and surface configuration, quantity of dentinal structure, and materials and techniques used in reconstruction [6 8].
The magnet of the FFHR consists of continuous windings with a large diameter, twisted configuration and large magnetic energy.
Therefore, the design of NWs including diameter, length, configuration, and density is originally determined by that of the Au droplet catalysts.
Different scenarios with various parameters, such as spacing between boreholes, borehole diameter and configuration, thermal conductivity of soil, are given for simulation.
We summarized the fundamentals of morphology formation as fiber diameter, surface configuration and continuity with different processes investigated in the latest reports.
The diameter, size, configuration, and even the density of NWs can innately be determined by those of the Au catalysts, and thus, the control of Au droplets is an essential step for the successful fabrication of the desired NWs.
These patients included in our study showed slight improvement of vasospasm but not complete normalization of vessel diameter and configuration.
The two configurations of the posterior part of the circle of Willis, the non-foetal configuration (diameter PCoA < diameter P1) and the foetal configuration (diameter PCoA > diameter P1), were analysed.
Of the 81 hemispheres in which a PCoA was present, there was a foetal configuration (diameter PCoA > diameter P1) in 16 hemispheres and a non-foetal configuration (diameter PCoA < diameter P1) in 65 hemispheres.
