Full-field modeling of heat transfer in asteroid regolith: Radiative thermal conductivity of polydisperse particulates [PDF]
, 2020 Characterizing the surface material of an asteroid is important for understanding its geology and for informing mission decisions, such as the selection of a sample site. Diurnal surface temperature amplitudes are directly related to the thermal properties of the materials on the surface.

A computational study of expiratory particle transport and vortex dynamics during breathing with and without face masks [PDF]
, 2021 We present high-fidelity numerical simulations of expiratory biosol transport during normal breathing under indoor, stagnant air conditions with and without a facial mask. We investigate mask efficacy to suppress the spread of saliva particles that is underpinnings existing social distancing recommendations.

Emission Standards for Particulates [PDF]
Journal of the Air Pollution Control Association, 1974 Promulgation of standards of performance under Section 111 and national emission standards for hazardous pollutants under Section 112 of the Clean Air Act is the responsibility of the Emission Standards and Engineering Division of EPA. The problems encountered and the bases used are examined.

Elemental and isotopic compositions in blank filters collecting atmospheric particulates
Journal of Analytical Science and Technology, 2021 Background The atmospheric particulates can be harmful to human health due to toxic substances sorbed onto particulates. Although the atmospheric particulates have been collected using different types of filters, few studies have reported background ...

Aggregate Particles in the Plumes of Enceladus [PDF]
Icarus, Volume 264, 15 January 2016, Pages 227-238, 2015 Estimates of the total particulate mass of the plumes of Enceladus are important to constrain theories of particle formation and transport at the surface and interior of the satellite. We revisit the calculations of Ingersoll & Ewald (2011), who estimated the particulate mass of the Enceladus plumes from strongly forward scattered light in Cassini ISS ...
