Physical Properties of Five Grain Dust Types [PDF]

open access: yesEnvironmental Health Perspectives, 1986
Physical properties of grain dust derived from five grain types (soybean, rice, corn, wheat, and sorghum) were measured and reported. The grain dusts were obtained from dust collection systems of terminal grain handling facilities and were assumed to be representative of grain dust generated during the handling process. The physical properties reported

Inhomogeneous cloud coverage through the Coulomb explosion of dust in substellar atmospheres [PDF]

open access: yes, 2015
Context. Recent observations of brown dwarf spectroscopic variability in the infrared infer the presence of patchy cloud cover. Aims. This paper proposes a mechanism for producing inhomogeneous cloud coverage due to the depletion of cloud particles ...

Assessment of a Mid-Fidelity Numerical Approach for the Investigation of Tiltrotor Aerodynamics

open access: yesApplied Sciences, 2021
The study of the complex aerodynamics that characterise tiltrotors represents a challenge for computational fluid dynamics tools. URANS numerical solvers are typically used to explore the aerodynamic features that characterise the different flight ...

The new physics of dust in plasmas

open access: yesJournal of Physics: Conference Series, 2021
Abstract The new physics of dust, which arises due to dust-plasma interaction in space environments and laboratory devices, is presented. The new research horizons (different new fields of physics involving many challenging research problems and open issues) introduced by this new physics of dust in plasmas are explained.

PHYSICAL PROPERTIES OF LUMINOUS DUST-POOR QUASARS [PDF]

open access: yesThe Astrophysical Journal, 2013
We identify and characterize a population of luminous dust poor quasars at 06 previously. This class of active galactic nuclei has been known to show little IR emission from a dusty structure, but is yet poorly understood in terms of number evolution or of dependence on physical quantities.

Charge Measurement of Dust Particles on Photovoltaic Module [PDF]

open access: yes, 2013
Photovoltaic (PV) systems are one of the most promising renewable energy sources in the world, and hence it is important to explore the factors that affect the working / operational efficiency of this source.

Effects of Barnett Magnetic Dipole–Dipole Interaction on Grain Growth and Destruction

open access: yesThe Astrophysical Journal, 2023
Rapidly spinning magnetic grains can acquire large magnetic dipole moments due to the Barnett effect. Here we study the new effect of Barnett magnetic dipole–dipole interaction on grain–grain collisions and grain growth, assuming that grains are spun up ...

Physical Properties of the Interplanetary Dust [PDF]

open access: yesInternational Astronomical Union Colloquium, 1971
The interplanetary dust may be composed of cometary material, interstellar grains, debris from asteroidal collisions, primordial material formed by direct condensation, or contributions from all of these sources. Before we can determine the origin of the dust, we need to know its physical nature, spatial distribution, and the dynamical forces that act ...

Heliotropic dust rings for Earth climate engineering [PDF]

open access: yes, 2013
This paper examines the concept of a Sun-pointing elliptical Earth ring comprised of dust grains to offset global warming. A new family of non-Keplerian periodic orbits, under the effects of solar radiation pressure and the Earth's J(2) oblateness ...
