Automated width measurements of Martian dust devil tracks
(Elsevier B.V., 2016-03-01)
Studying dust devils is important to better understand Mars climate and resurfacing phenomena. This paper presents an automated approach to calculate the width of tracks in orbital images. The method is based on Mathematical ...
A multiwavelength study of young massive star forming regions. II. The dust environment
We present observations of 1.2 mm dust continuum emission made with the Swedish-ESO Submillimeter Telescope toward 18 luminous IRAS point sources, all with colors typical of compact H II regions and associated with CS(2 ...
High particulate iron(II) content in glacially sourced dusts enhances productivity of a model diatom
(American Association for the Advancement of Science, 2017-06)
Little is known about the bioavailability of iron (Fe) in natural dusts and the impact of dust mineralogy on Fe utilization by photosynthetic organisms. Variation in the supply of bioavailable Fe to the ocean has the ...
A FACILE AND EFFICIENT SYNTHESIS OF HIGHLY FUNCTIONALIZED TERMINAL OLEFINES FROM á-ALKOXY-ß-HALIDES USING ZINC DUSTΨ
(Sociedad Chilena de Química, 2009)
Glyphosate and Aminomethylphosphonic acid (AMPA) contents in the respirable dust emitted by an agricultural soil of the central semiarid region of Argentina
(Elsevier Science, 2017-12)
One environmental issue in the semiarid Pampas of Argentina and elsewhere is the possible accumulation of glyphosate [N-(phosphonomethyl) glycine] and aminomethylphosphonic acid (AMPA, the main metabolite of the microbial ...
Benchmarking the calculation of stochastic heating and emissivity of dust grains in the context of radiative transfer simulations
(EDP Sciences, 2015)
Context. Thermal emission by stochastically heated dust grains (SHGs) plays an important role in the radiative transfer (RT) problem for a dusty medium. It is therefore essential to verify that RT codes properly calculate ...
Attenuation modified by DIG and dust as seen in M31
(IOP Publishing Ltd, 2017)
The spatial distribution of dust in galaxies affects the global attenuation, and hence inferred properties, of galaxies. We trace the spatial distribution of dust in five approximately kiloparsec fields of M31 by comparing ...
Detecção automática de rastros de Dust Devils na superfície de Marte
(Universidade Estadual Paulista (UNESP), 2014)
Atmospheric dust accumulation on native and non-native species: effects on gas exchange parameters
(Amer Soc Agronomy, 2014-06)
Plants are continuously exposed to atmospheric particulate matter (dust), and their leaves are the main receptors of deposited dust. The objective of this study was to assess the effects of dust deposition on leaf gas ...
Polarization in Monte Carlo radiative transfer and dust scattering polarization signatures of spiral galaxies
(EDP Sciences, 2017-05)
Polarization is an important tool to further the understanding of interstellar dust and the sources behind it. In this paper we describe our implementation of polarization that is due to scattering of light by spherical ...
