Study of the effect on greenhouse gas emissions of vehicles powered by hydrogen generators
This article presents four case studies carried out in the city of Bogotá - Colombia, on the reduction of emissions in
private transport vehicles using Hydrogen Generators (HGE) by water electrolysis (electrolytic cells). ...
Nitrous oxide emission after the addition of organic residues on soil surface
(Elsevier Science, 2017-08)
The addition of organic amendments with a low Carbon:Nitrogen (C:N) ratio to restore degraded soils may increase the emission of greenhouse gases and affect the storage of these elements in the topsoil. Our objectives were ...
Are ch4, co2, and n2 o emissions from soil affected by the sources and doses of n in warm-season pasture?
(2021-06-01)
The intensification of pasture production has increased the use of N fertilizers—a practice that can alter soil greenhouse gas (GHG) fluxes. The objective of the present study was to evaluate the fluxes of CH4, CO2, and ...
Direct determination of aluminum in low-enriched UALx targets ( UAlx-Al) by inductively coupled plasma optical emission spectrometry
(Associa????o Brasileira de Energia Nuclear, 2019)
Contrasting Effects of Nitrogen and Labile Carbon Addition on N2O Emissions from Andosols in Costa Rica and Chile Under Controlled Conditions
(2022-07-20)
Our study analyzes nitrous oxide (N2O) emissions of two volcanic soils, from a tropical (Costa Rica) and temperate (Chile) environment. Volcanic origin soils are important for dairy production in both countries and ...
Region-specific emission factors for Brazil increase the estimate of nitrous oxide emissions from nitrogen fertiliser application by 21%
(Elsevier, Ámsterdam, Países Bajos, 2020)
The use of synthetic nitrogen fertilisers is one of the most important land management practices proposed to improve crop and pasture productivity. The use of such fertilisers in excess can lead to greenhouse gas (GHG) ...
