PM10 emission efficiency for agricultural soils: Comparing a wind tunnel, a dust generator, and the open-air plot
(Elsevier, 2018-06)
The PM10 emission efficiency of soils has been determined through different methods. Although these methods imply important physical differences, their outputs have never been compared. In the present study the PM10 emission ...
Gross, background, and net anthropogenic soil nitrous oxide emissions from soybean, corn, and wheat croplands
(American Society of Agronomy, 2019-01)
Agricultural soils are the largest single source of N2O emissions globally. However, soils left uncultivated would still release N2O. Distinguishing anthropogenic from natural emissions (i.e., background emissions) in crops ...
Experimental research on the effects of water application on greenhouse gas emissions from beef cattle feedlots
(2014-04-30)
The effect of water application (e.g., through rainfall or sprinkler system) on emissions of greenhouse gases (GHGs), such as nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2), from pen surfaces of open-lot beef ...
Emission of primordial bosonic radiation during inflation
(National Research Council Canada-NRC Research Press, 2018-05)
We study the emission of neutral massless (1, 2)h-spin bosons during power-law inflation using unified spinor field theory. We show that during inflation, gravitons and photons were emitted with wavelengths (on physical ...
PM10 emission efficiency for agricultural soils: Comparing a wind tunnel, a dust generator, and the open-air plot
(Elsevier, 2018)
The PM10 emission efficiency of soils has been determined through different methods. Although these methods
imply important physical differences, their outputs have never been compared. In the present study the PM10

Higher than expected N2O emissions from soybean crops in the Pampas Region of Argentina: Estimates from DayCent simulations and field measurements
(Elsevier, 2022-08)
In developing countries, agriculture generally represents a large fraction of GHG emissions reported in National Inventories, and emissions are typically estimated using Tier 1 IPCC guidelines. However, field data and ...
Cathode-sheath model for field emission sustained atmospheric pressure discharges
(American Institute of Physics, 2021-03)
The cathode-sheath region of a discharge in atmospheric pressure air with a flat copper cathode is numerically investigated by using a simple fluid model that takes into account non-local ionization. The effects of the ...
Photoelectron emission from LiF surfaces by ultrashort electromagnetic pulses
(American Physical Society, 2011-03)
Energy- and angle-resolved electron emission spectra produced by incidence of ultrashort electromagnetic pulses on a LiF(001) surface are studied by employing a distorted-wave method named the crystal surface–Volkov (CSV) ...
Spontaneous emission in plasmonic graphene subwavelength wires of arbitrary sections
(Pergamon-Elsevier Science Ltd, 2018-02)
We present a theoretical study of the spontaneous emission of a line dipole source embedded in a graphene–coated subwavelength wire of arbitrary shape. The modification of the emission and the radiation efficiencies are ...
Greenhouse Gas Emissions from Green-Harvested Sugarcane With and Without Post-harvest Burning in Tucumán, Argentina
(2014-06)
Concentrations of greenhouse gases (GHG) in the atmosphere are increasing due to anthropogenic actions, and agriculture is one of the most important contributors. This study quantified GHG emissions from green-cane harvested ...
