Introduction: In our study, we aimed 200 cases were evaluated for the length, width and angle of hyoid bone and its distance from certain anatomical structures. Methods: This study was perfomed retrospectively in 2010 - 2013 on 200 CT images. 3D volume rendering images of pure hyoid bone were created from the axial CT images in 1 mm slice thickness. In our study, 200 cases (94 female, 106 male...
This paper falls within the scope of current concerns for scientific and technical research, relating to structures made composite materials, recognized their mechanical, thermal chemical or erosive resistance characteristics. In this case, study is characterized by analysis bearing capacity some composites: a) with fibers applied along them, b) in a certain direction, c) direction perpendicula...
In this paper, we establish a topological framework of τ-structures to quantify the evolutionary transitions between two RNA sequence–structure pairs. developed here consist pair secondary structures together with non-crossing partial matching backbones. The loop complex τ-structure captures intersections loops in both structures. We compute homology τ-structures. show that only zeroth, first a...
