Marine particles play an important rôle in the chemistry of the oceans, not only because they provide sources of, and sinks for, solutes, but also, and especially, because they move relative to water. Examples of the resulting fluxes can be seen in the vertical transport of organic carbon and nitrogen, calcium carbonate, or trace metals. The components

International Journal of Theoretical Physics, 1989
Applying a finite color symmetry group, it is shown that every “elementary particle” can be associated with a unique graph. This graph describes the gluon motions and is called the particle's strong graph. One also has an associated weak graph that describes the photon motions.

Roughness models for particle adhesion
Journal of Colloid and Interface Science, 2004The effects of different surface roughness models on a previously developed van der Waals adhesion model were examined. The van der Waals adhesion model represented surface roughness with a distribution of hemispherical asperities. It was found that the constraints used to define the asperity distribution on the surface, which were determined from AFM ...

Publisher Summary Particle modeling is the study of the dynamical reaction of a material body to external forces. The mathematical equations of particle modeling are large systems of nonlinear, second-order ordinary differential equations, rather than small systems of partial differential equations.

Compound Model for Heavy Particles
Physical Review, 1957A static model is considered in which all heavy particles are compounded out of two basic units, taken here to be the $\ensuremath{\Lambda}$ and nucleon $N$ (and/or the cascade particle $\ensuremath{\Xi}$). The model suggests the existence of some unstable particle states accessible to experiment: the $\ensuremath{\rho}$ meson, a boson with $I=0$; the $

In real plasmas, the electrons and ions can stream along magnetic field lines, gyrate around a magnetic field line, bounce back and forth in either an electric or magnetic trap, drift and precess across the magnetic field, and collide with other particles Each of these motions usually possesses its own characteristic frequency, and the large difference

In this chapter we present briefly the formalism of the Fermi-gas model (Sect. 1.1), the shell model (Sect. 1.2) and the Hartree-Fock method (Sect. 1.3). These examples of models and methods in the framework of the mean-field approximation, as well as the one-body density matrix, and the density and nucleon momentum distributions are necessary to ...
