Introduction: Magnetic Resonance Elastography (MRE) is an MRI-based method for imaging the mechanical properties of tissue [1]. The technique has been shown to be capable of measuring the elasticity of skeletal muscle [2, 3]. The MRE needle driver developed in our laboratory [4] is possible to introduce shear motion directly to adjacent muscle by vibrating the needle. The objective of this stud...

Rhenium diboride is a recently recognized ultra-incompressible superhard material. Here we report the electronic (e), phonon (p), e-p coupling, and thermal properties of ReB2 from first-principles densityfunctional theory calculations and neutron scattering measurements. Our calculated elastic constants (c11 =641 GPa, c12=159 GPa, c13=128 GPa, c33=1037 GPa, and c44=271 GPa), bulk modulus (B≈350...

Aim/purpose – The aim of this paper is to present a strategy that allows companies recover from disasters, when creating supply chain. Furthermore, it also shows the impact on company’s resources are used in implementation case small and big disasters. Thanks proposed solution, possible analyze each company individually, as well groups, at any given time. Design/methodology/approach results wer...

Theories on superheating-melting mostly involve vibrational and mechanical instabilities, catastrophes of entropy, volume and rigidity, and nucleation-based kinetic models. The maximum achievable superheating is dictated by nucleation process of melt in crystals, which in turn depends on material properties and heating rates. We have established the systematics for maximum superheating by incor...

The elastic constants of Nd3Se4 show an anomalous behaviour above and below Tc = 52 K. Band effects are assumed to be the origin of the softening of C' in the paramagnetic region. Below Tc extra shifts arise from magneto-elastic coupling. An elastic hysteresis is observed which is directly related to the magnetic hysteresis loop. The metallic rare earth chalcogenides of RE3X4 type have attracte...

Banks, in order to extend the development of information technology and electronic banking services and its using by customers, in first place, should examine barriers and problems in using information technology. Therefore, in this study we deal with identifying and prioritizing these barriers in Iranian banks. Our method in this research is descriptive-survey. In this way, after the library s...

For a given crystal structure, say body-centred-cubic, the many-body Hamiltonian H in which nuclear and electron motions are to be treated from the outset on the same footing, has parameters, for the elements, which can be classified as (i) atomic mass M , (ii) atomic number Z, characterizing the external potential in which electrons move, and (iii) bcc lattice spacing, or equivalently one can ...

An explicit integral representation by single definite integrals of the fundamental matrix (Green’s tensor) of the time-dependent system of hexagonal elastic media is derived. Thereby the problem of internal conical refraction in such media is solved. 0. Introduction and notations Hexagonal or transversely isotropic media are characterized by the property of rotational symmetry with respect to ...
