and spin–spin relaxation rates in CuV2S4

Physica B: Condensed Matter, 1999
Abstract 63 Cu and 51 V spin–spin relaxation rates have been measured in CuV2S4 which reveals CDW transition. 63 Cu spin echo decays as Gaussian while 51 V spin echo does as Lorentzian. Both 63 Cu and 51 V spin–spin relaxation rates show remarkable changes due to CDW transition.

Ball spin in the tennis serve: spin rate and axis of rotation

Sports Biomechanics, 2013
The purpose of this study was to describe three-dimensional ball kinematics including spin axis and spin rate for the flat, slice, and kick serves executed by elite male tennis players. Trajectories of three retro-reflective markers attached to the surface of the ball were measured using a Vicon MX motion analysis system. The local coordinate system of

The rate of spreading in spin coating

Journal of Fluid Mechanics, 2000
In this paper we reconsider the fundamental problem of the centrifugally driven spreading of a thin drop of Newtonian fluid on a uniform solid substrate rotating with constant angular speed when surface-tension and moving-contact-line effects are significant.

Galileo spin rate control

Astrodynamics Conference, 1982
This paper presents the analysis and design of the spin rate control flight algorithm for the dual-spin Galileo spacecraft. Because of thruster plume contamination constraints, only one poorly located thruster is available for spin rate correction in each spin direction.

Potential Energy Surfaces and Rates of Spin Transitions

Zeitschrift für Physikalische Chemie, 2013
The stability of magnetic states and the mechanism for magnetic transitions can be analyzed in terms of the shape of the energy surface, which gives the energy as a function of the angles determining the orientation of the magnetic moments. Minima on the energy surface correspond to stable or metastable magnetic states and can represent parallel ...

The spin-spin relaxation rate of paramagnetic impurities in antiferromagnets

Solid State Communications, 1982
Abstract The interaction between paramagnetic impurities in easy plane type antiferromagnets at finite temperatures is considered. In the framework of the diagram spin-operator technique the spin-spin relaxation rate Γ of paramagnetic impurities is investigated.

Reduction and destruction rates of nitroxide spin probes

Archives of Biochemistry and Biophysics, 1987
A series of nitroxides was tested for rates of one-electron reduction in a chemical, a photochemical, and two biological systems by ESR assays. In all cases, piperidine and hydropyridine nitroxides were reduced consistently more rapidly than pyrroline and pyrrolidine nitroxides. Substituents on the nitroxides also affected reduction rates, although not

CFD Prediction for Spin Rate of Fixed Canards on a Spinning Projectile

AIP Conference Proceedings, 2011
A computational study performed for spin rate of fixed canards on a spinning projectile is presented in this paper. The cancards configurations provide challenges in terms of the determination of the aerodynamic forces and moments and the flow field changes which could have significant effect on the stability, performance, and corrected round accuracy.

Direction of spin axis and spin rate of the pitched baseball.

Sports biomechanics, 2007
In this study, we aimed to determine the direction of the spin axis and the spin rate of pitched baseballs and to estimate the associated aerodynamic forces. In addition, the effects of the spin axis direction and spin rate on the trajectory of a pitched baseball were evaluated.

Spin vectors and rates of change of wind direction

Quarterly Journal of the Royal Meteorological Society, 1988
AbstractEstablished formulae for various rates of change of horizontal wind direction may be unified by a treatment in terms of the spin vector, S, of a vector field M. The spin vector measures the rate of change of direction of M, in the appropriate osculating plane, and may be defined with respect to any infinitesimal displacement in space and time ...
