Greenhouse gases emissions from tropical grasslands affected by nitrogen fertilizer management
(2020-11-01)
Greenhouse gases (GHGs) emissions from livestock systems are important because of their significant contribution to global warming. Nitrogen fertilization can improve system production; however, it alters soil gas emissions. ...
Assessment Of Co2 Emission Mitigation For A Brazilian Oil Refinery
(Brazilian Soc Chemical EngSão Paulo, 2016)
1.5 mu m and visible up-conversion emissions in Er3+/Yb3+ co-doped tellurite glasses and optical fibers for photonic applications
(Royal Soc Chemistry, 2012-01-01)
Glasses with base composition (in mol%) 70TeO(2)-15GeO(2)-5K(2)O-10Bi(2)O(3) were prepared by the melt-quenching method. Er3+/Yb3+-doped and non-doped glass compositions were used as core and cladding, respectively, in the ...

High-resolution atmospheric emission inventory of the argentine energy sector. Comparison with edgar global emission database
(Elsevier, 2017-12)
This study presents a 2014 high-resolution spatially disaggregated emission inventory (0.025°× 0.025° horizontal resolution), of the main activities in the energy sector in Argentina. The sub-sectors considered are public ...
Greenhouse gas emissions from green-harvested sugarcane with and without postharvest burning in Tucumán, Argentina
(Springer India, 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 greencane ...
Greenhouse gas balance due to the conversion of sugarcane areas from burned to green harvest in Brazil
(Elsevier B.V., 2011-04-01)
Strategies for the reduction of greenhouse gas emission in agriculture have been debated for some time, especially in Brazil, where the agricultural sector is an important contributor to the national emission balance. The ...
