Figure 1b: A 10-year post-treatment radiograph reveals excellent healing and confirms the importance of treating root canal systems. Introduction There are enormous differences in opinion regarding the potential to 3-dimensionally clean a root canal system. Elimination of pulpal tissue, bacteria (when present), and their related breakdown products is directly influenced by a series of procedura...

We review the apparently hydrodynamic behaviour of low transverse momentum particles (pT ≤ 1.5 GeV/c) produced in central and semicentral (b ≤ 7 fm) heavy ion collisions at RHIC. We investigate the impact parameter dependence of various observables, elaborating on radial and elliptic flow and particle multiplicities. We also discuss possible ambiguities in the initialization of the hydrodynamic...

In the hydrodynamic description of ferronematics there are various dynamic magnetic-field effects, linear in the field strength, that are negligible in usual nematics, but can play a role in ferronematics. Here, we investigate theoretically the influence of these new terms on the thermal convection (Rayleigh-Bénard) and the viscous fingering (Saffman-Taylor) instability in ferronematics in the ...

Submitted for the DFD10 Meeting of The American Physical Society Hydrodynamic interaction of two unsteady squirmers TAKUJI ISHIKAWA, DAVIDE GIACCHE, Tohoku University — The study of pair-wise interactions between swimming microorganisms is fundamental to the understanding of the rheological and transport properties of semi-dilute suspensions. In this study, the hydrodynamic interaction of two c...

This paper is a continuation of a series of papers in which (quasi-) hydrodynamic models for plasmas are rigorously derived by means of asymptotic analysis. Here, the quasi-neutral limit (zero-Debye-length limit) in the drift-diiusion equations is performed in the two cases: weakly ionized plasmas and not weakly ionized plasmas. The model consists of the continuity equations for the electrons a...

We use the Brownian dynamics with hydrodynamic interactions simulation in order to describe the movement of an elastically coupled dimer Brownian motor in a ratchet potential. The only external forces considered in our system were the load, the random thermal noise and an unbiased thermal fluctuation. We observe differences in the dynamic behaviour if hydrodynamic interactions are considered as...

Chapman-Enskog expansion is the orthodox approach to derive continuum flow models from Boltzmann’s kinetic equation for dilute gases. Beyond the Navier-Stokes-Fourier order, these models known as Burnett hydrodynamic-regime equations violate a number of fundamental mechanical and thermodynamic principles in their original forms. This has generated a widely investigated problem in the kinetic th...

The pseudorapidity dependence of elliptic flow in Au+Au collisions at 130 A GeV is studied within a full three-dimensional hydrodynamic model in the light-cone coordinate. First, we prepare two initial conditions in the hydrodynamic model for analyzing elliptic flow. Both initial conditions lead to reasonable agreement with single particle spectra in central and semi-central collisions. Next, b...

We present a numerical method for studying the normal modes of accretion flows around black holes. In this first paper, we focus on two-dimensional, viscous, hydrodynamic disks in pseudo-Newtonian potentials, for which the linear modes have been calculated analytically in previous investigations. We use a pseudo-spectral algorithm to evolve the hydrodynamic equations and devise a number of test...
