Interference factors regarding the path of insertion of rotational-path removable partial dentures

Biomedical Journal, 2017
Background: The aims of this study were to evaluate the effect of the location of the rotational center and the morphology of teeth resulting in interference with the rotational path of insertion and to estimate when an interference test should be ...

Rotational symmetry of Weingarten spheres in homogeneous three-manifolds [PDF]

Journal für die Reine und Angewandte Mathematik, 2018
Let M be a simply connected homogeneous three-manifold with isometry group of dimension 4, and let Σ be any compact surface of genus zero immersed in M whose mean, extrinsic and Gauss curvatures satisfy a smooth elliptic relation Φ ⁢ ( H , K e , K ) = 0 {

Heat transport investigation of engine oil based rotating nanomaterial liquid flow in the existence of partial slip effect

Case Studies in Thermal Engineering, 2021
In this study, rotational nano liquid movement above a linearly stretching surface has been formulated. A two-phase model is used for this analysis. Base fluid engine oil and two distinct types of nanoparticles are used as nanoparticles, i.e.

Influence of rotational speed on surface states after stream finishing

, 2018
The stream finishing process proved to be an efficient production process for mechanical surface modification. In particular the rotational speed of a bowl containing the media represents an effective process variable for increasing relative velocity ...

Study of adhesivity of surfaces using rotational optical tweezers [PDF]

Physica Scripta, 2018
Optical tweezers are powerful tools for high resolution study of surface properties. Such experiments are traditionally performed by studying the active or the Brownian fluctuation of trapped particles in the X, Y and Z directions.

The odd free surface flows of a colloidal chiral fluid

Nature Physics, 2019
In simple fluids, such as water, invariance under parity and time-reversal symmetry imposes that the rotation of constituent ‘atoms’ is determined by the flow and that viscous stresses damp motion.

Nonreciprocal surface acoustic wave propagation via magneto-rotation coupling

Science Advances, 2020
Coupling of surface acoustic waves with anisotropic magnets demonstrates 100% nonreciprocity. A fundamental form of magnon-phonon interaction is an intrinsic property of magnetic materials, the “magnetoelastic coupling.” This form of interaction has been

Theoretical analysis and experimental verification on optical rotational Doppler effect. [PDF]

Optics Express, 2016
We present a theoretical model to sufficiently investigate the optical rotational Doppler effect based on modal expansion method. We find that the frequency shift content is only determined by the surface of spinning object and the reduced Doppler shift ...
