This is in agreement with Mishra et al [3] who concluded that high ratio of tool rotational speed to welding speed leads to an increase in the degree of deformation which results in a reduction in the recrystallized grain size.

These experimental results confirm the development of the processes described by Seo [21] and El Briak-Ben Abdeslam [22].
Morphological aspects of MM-ed HAP powder particles: c) after 10 hours Chemical composition Our research confirms the mechanisms of wet MM set by El Briak-Ben Abdeslam et al. [22]: the liquid presence in the milling vial “cleans” the interface between the milling balls during the mutual collision and thus, the contamination phenomenon occurs.

Mixed Ti, Si, graphite and Al powder with molar ratio of 3Ti:1Si:2C:0.2Al was put into a graphite mould and pressed with a pressure of about 0.5 MPa, then, Mo powder was put on top of the mixed powder.
Al powder was used as a sintering aid in this study.
EDS analysis on this grey phase indicated that it has a composition of Ti5Si3Cx (although it contains a few percent of Mo and Al, it is being named as Ti5Si3Cx phase here), while, the light grey intermediate layer was found with a composition of MoSi2 (although it contains a few percents of Mo and Al, it is being named as MoSi2 phase here), as shown in Table 1.

According to the “iodide- induced mechanism” of Ha et al.[27], the authors proposed a possible mechanism, involving inhibition of {111} facets by strongly bonded halide ions, which increases in the order Cl- < Br- < I-.
Cheng et al [28] also observed similar aggregated gold structures in their study on the effect of KI on the morphology of AuNPs prepared by the citrate reduction method, the results further proved that halide ions have a dramatic formation of nanoparticle superstructures.

Gooya et al. [5][6] proposed an energy edge detector for vessel segmentation using the structural tensor.
Descoteaux et al. [8] proposed a boundary vessel segmentation by convolving an image with Gaussian filters at multiple scales to drives the shape evolution.
Also, other interesting methods have been presented in Manniesing et al.[10], Nemitz et al. [11], Hernández Hoyos et al. [12], Orkisz et al. [13].
Description of the proposed molde The model proposed by Li et al.[24] is based on Mumford-Shan model, so it is still a piecewise constant.

The absorption frequency of TeO3 group is higher than those of TeO4 group as reported by Gayatri et al. [12].
According to Bürger et al. [13], the occurrence of IR absorption bands around ~670 and ~800 cm-1 are related to the symmetric,and asymmetric stretching vibrations, respectively.
