A new dust generator for laboratory dust emission studies
(Elsevier Science, 2013-03)
The aim of this study was to develop a cheap and replicable dust generator for production and investigation of fugitive dusts. We call the device the Easy Dust Generator (EDG). The EDG was constructed with common materials ...
A study on automatic methods based on mathematical morphology for Martian dust devil tracks detection
This paper presents three methods for automatic detection of dust devils tracks in images of Mars. The methods are mainly based on Mathematical Morphology and results of their performance are analyzed and compared. A dataset ...
In and out of glacial extremes by way of dust climate feedbacks
(National Academy of Sciences, 2018)
Mineral dust aerosols cool Earth directly by scattering incoming solar radiation and indirectly by affecting clouds and biogeochemical cycles. Recent Earth history has featured quasi-100,000-y, glacial-interglacial climate ...
Copper Flash Smelting Flue Dust as a Source of Germanium
Global connections between aeolian dust, climate and ocean biogeochemistry at the present day and at the last glacial maximum
(Elsevier Science, 2010-06)
Palaeo-dust records in sediments and ice cores show that wind-borne mineral aerosol ('dust') is strongly linked with climate state. During glacial climate stages, for example, the world was much dustier, with dust fluxes ...
Organic characterisation of PM10 in Cape Verde under Saharan dust influxes
(Pergamon-elsevier Science LtdOxfordInglaterra, 2014)
Subregional inversion of North African dust sources
(AMER Geophysical Union, 2016)
The emission of mineral dust aerosols in arid and semiarid regions is a complex process whose representation in atmospheric models remains crude, due to insufficient knowledge about the aerosol lifting process itself, the ...
South American dust signature in geological archives of the Southern Hemisphere
(PAGES International Project Office, 2014-10)
Patagonian dust is the darling of researchers of paleoclimatic variability of southern South America. However, new chemical data from yet unexplored dust source areas allows for deeper investigation of the geological ...
Detecção automática de rastros de Dust Devils na superfície de Marte
(Universidade Estadual Paulista (UNESP), 2012-05-17)
Dust Devils são vórtices convectivos formados por correntes de ar quente instáveis, próximas à superfície planetária. Inúmeros pesquisadores têm estudado dust devils marcianos na tentativa de melhor entender o fenômeno. ...
