A methodology to select particle morpho-chemical characteristics to use in source apportionment of particulate matter from livestock houses

Cambra López, María; Hermosilla Gómez, Txomin; Aarnink, André Johannes Antonius; Ogink, Nico (Elsevier, 2012-02)

[EN] Intensive poultry and pig houses are major point sources of particulate matter (PM) emissions. The knowledge on the contribution of individual sources to PM in different fractions is essential to improve PM reduction ...
Comparative study of regulated and unregulated gaseous emissions during NEDC in a light-duty diesel engine fuelled with Fischer Tropsch and biodiesel fuels

Bermúdez, Vicente; Luján, José M.; Plá Moreno, Benjamín; Linares Rodríguez, Waldemar Gregorio (Elsevier, 2011-02)

In this study, regulated and unregulated gaseous emissions and fuel consumption with five different fuels were tested in a 4-cylinder, light-duty diesel EURO IV typically used for the automotive vehicles in Europe. Three ...
Effect of water and straw management practices on methane emissions from rice fields: A review through a meta-analysis

Sanchís Jiménez, Elena María; Ferrer Roglán, Marta; Torres, Antonio G.; Cambra López, María; Calvet Sanz, Salvador (Mary Ann Liebert, 2012-12)

[EN] Rice fields contribute substantially to global warming of the atmosphere through emission of methane (CH4). This article reviews the state of the art of factors affecting CH4 emissions in rice fields, focusing on soil ...
Effects of low pressure exhaust gas recirculation on regulated and unregulated gaseous emissions during NEDC in a light-duty diesel engine

Bermúdez, Vicente; Luján, José M.; Plá Moreno, Benjamín; Linares Rodríguez, Waldemar Gregorio (Elsevier, 2011-09)

Regulated and unregulated gaseous emissions with high pressure and low pressure EGR (exhaust gas recirculation) system were tested in a 4-cylinder, light-duty diesel EURO IV engine typically used in European vehicles. Four ...
