This study aims to validate, using finite element analysis (FEA), the design concept by comparing the fatigue behavior of hip implant stems coated with composite (carbon/PEEK) and polymeric (PEEK) coating materials corresponding to different human activities: standing up, normal walking and climbing stairs under dynamic loadings to find out which of all these models have a better performance in...

The mixed valence multiferroic LnFe2+Fe3+O4 (where Ln = Y, Lu, and Yb) can reversibly uptake oxygen into its lattice, which is evidenced by a crystallographic phase transition along with the appearance of structural modulations. In this study, we show that Mn-substituted version also be readily oxidized to LnFe3+Mn3+O4.5 revealing similar storage behavior. Through neutron, electron, synchrotron...

The site of Kul Tepe is located near the city of Hadishahr, in Eastern Azerbaijan Province. It is an ancient multi-period mound, having an extension of about 6 hectares and rising 19 meters above the surrounding land. The second season of archeological excavations at the site, carried out in 2013, aimed at clarifying its chronology and its settlement organization. In the meantime it aimed at el...

This paper discusses the design and modeling fundamentals of a multi-degree-of-freedom reconfigurable robotic gripper system (RGS), designed to automate the process of limp material handling, reliably and without distortion, deformation, and/or folding. The reconfigurable gripper design draws upon the authors' previously reported flat surfaced, fixed-dimensions gripper system [1]. The design co...

Alveolar augmented corticotomy is effective in accelerating orthodontic tooth movement, but the effect only lasts for a relatively short time. Therefore, the purpose of this study was to investigate the underlying biology of the immediate periodontal response to orthodontic tooth movement after a corticotomy with alloplastic bone grafts. The results demonstrated that measurable tooth movement b...

Autonomous material search systems that combine ab initio calculations and Bayesian optimization are very promising for exploring huge spaces. Setting up an appropriate space is necessary efficient autonomous search. However, performing the within set using prepared descriptors not sufficient to obtain search, which can be achieved by prioritizing specific properties. Here, a system autonomousl...

Five new crystalline zeolitic imidazolate frameworks (ZIFs), ZIF-78 to -82, were prepared from zinc(II) nitrate and mixtures of 2-nitroimidazole and five different functionalized imidazoles and were found to have the GME topology. These structures, along with three previously reported GME ZIFs, constitute a series of highly porous materials with Brunauer-Emmet-Teller surface areas ranging from ...
