Gravitons emission during pre-inflation from unified spinor fields
(Springer, 2018-12)
We obtain the equation that describe the conditions of quantization for neutral massless bosons on an arbitrary curved space-time, obtained using a particular theoretical formalism developed in a previous work (M.R.A. ...
Enhancement, suppression of the emission and the energy transfer by using a graphene subwavelength wire
(Pergamon-Elsevier Science Ltd, 2018-07)
The present work focuses on theoretically research on the spontaneous emission and the energy transfer process between two single optical emitters placed close to a graphene coated wire. The localized surface plasmons ...
Photoelectron emission from metal surfaces by ultrashort laser pulses
(American Physical Society, 2006-12)
Electron emission from metal surfaces produced by short laser pulses is studied within the framework of the distorted-wave formulation. The proposed approach, named surface-Volkov (SV)approximation, makes use of the ...
Field measurements of agricultural emissions
(JRC Science Hub, 2015-01)
Nitrous oxide plays an important role for the balance of greenhouse gases (GHG) on agricultural soils, followed by carbon dioxide and methane. The methods that are used to calculate the GHG balance include theoretical ...
Some remarks about emission channels of non-Abelian vortices
(American Physical Society, 2021-06-30)
As is well established, several gauge theories admit vortices whose mean life time is very large. In some cases, this stability is a consequence of the topology of the symmetry group of the underlying theory. The main focus ...
Soil carbon dioxide and nitrous oxide emissions during the growing season from temperate maize‐soybean intercrops
(Wiley, 2012-06)
The Argentine Pampa is one of the major global regions for the production of maize (Zea mays L.) and soybean (Glycine max L. [Merr.]), but intense management practices have led to soil degradation and amplified greenhouse‐gas ...
Surface plasmon dispersion engineering for optimizing scattering, emission, and radiation properties on a graphene spherical device
(Optical Society of America, 2020-05)
We present a dispersion engineering method based on the rigorous electromagnetic theory to study the scattering properties of a double graphene layer spherical structure. The localized surface plasmons (LSPs) supported by ...
Potential CO2 emissions mitigation through forest prescribed burning: A case study in Patagonia, Argentina
(Elsevier Science, 2011-06-15)
Wildland fire is a natural force that has shaped most vegetation types of the world. However, its inappropriate management during the last century has led to more frequent and catastrophic fires. Wildland fires are also ...
Estimation of greenhouse gas emissions in the agro-industrial system of sugarcane in Piauí, Brazil
(Universidade Federal de Santa Maria, 2019)
Theoretical investigation of the spontaneous emission on graphene plasmonic antenna in THz regime
(Academic Press Ltd - Elsevier Science Ltd, 2018-10)
The present work deals with a theoretical research on the emission and radiation properties of a dipole emitter source close to a dimer graphene plasmonic antenna. Modification of the radiation and the quantum efficiencies ...
