Sinking microplastics in the water column: simulations in the Mediterranean Sea [PDF]

open access: yesOcean Science, 2021
We study the vertical dispersion and distribution of negatively buoyant rigid microplastics within a realistic circulation model of the Mediterranean sea. We first propose an equation describing their idealized dynamics.

Employing observed turbulent dissipation rates to obtain fundamental equations that parameterize turbulence effects in atmospheric models [PDF]

open access: yesRevista Brasileira de Meteorologia
Taylor diffusion model and forms for the autocorrelation functions are employed to derive turbulent dissipation rates. These formulations contain a numerical coefficient nc and are written in terms of turbulent scales associated with the energy ...

Nonlinear-dispersive similariton of passive fiber [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2009
Using the spectral-interferometry method for the short pulse complete characterization, we demonstrate the nature and distinctive properties of the similariton generated in single-mode fiber without gain (passive fiber) due to the combined impacts of ...

Impact of Mass-Gap on the Dispersion Interaction of Nanoparticles with Graphene out of Thermal Equilibrium

open access: yesApplied Sciences, 2023
We consider the nonequilibrium dispersion force acting on nanoparticles on the source side of a gapped graphene sheet. Nanoparticles are kept at the environmental temperature, whereas the graphene sheet may be either cooler or hotter than the environment.

The theory of electron states on the dynamically deformed adsorbed surface of a solid

open access: yesCondensed Matter Physics, 2018
Dispersion relations for the spectra of surface electron states on a dynamically deformed adsorbed surface of a monocrystal with the Zinc blende structure are received. It is established that the dependences of the band gap width and of the concentration

Numerical Simulation on Dispersal Character of Fuel by Central HE

open access: yesDefence Science Journal, 2007
A fuel-air explosive (FAE) device consists of a shell (top-end cover, bottom-end cover, shell-side wall), a mixed fuel, a central pipe and a burst high-explosive (HE) charged in the central pipe.The mixed fuel is filled in a column structure and dispersed by the explosion drive of central burstHE in the central pipe.

Terahertz spectroscopy of 2,4,6-trinitrotoluene molecular solids from first principles

open access: yesBeilstein Journal of Organic Chemistry, 2018
We present a computational analysis of the terahertz spectra of the monoclinic and the orthorhombic polymorphs of 2,4,6-trinitrotoluene. Very good agreement with experimental data is found when using density functional theory that includes Tkatchenko ...

Magnetostatic waves in a medium with damping

open access: yesEPJ Web of Conferences, 2018
By means of consistent solution of the motion equation for magnetization the consideration of energy dissipation for magnetostatic surface waves propagating on in-plane magnetized ferrite plate is regarded. The complex character of the wave number caused

Preparation, optimization, and characterization of genistein-ginseng long-acting polymeric gel as a breast cancer treatment alternative

open access: yesDiscover Oncology
To address the prevalent genistein (GST) metabolism and inadequate intestinal absorption, an oral long-acting and gastric in-situ gelling gel was designed to encapsulate and localize the intestinal release of the loaded genistein-ginseng (GST-GNS) solid ...
