Formación de hidrocarburos aromáticos policíclicos (HAP) y hollín en la pirólisis de hidrocarburos
Jornada de Jóvenes Investigadores del I3A, 1970 En la actualidad, cerca del 82 % del consumo energético español proviene de la combustión depetróleo, carbón y otros combustibles sólidos. Durante este proceso de conversión térmica, yen condiciones reductoras, cantidades considerables de hollín pueden formarse junto concenizas o compuestos que, en algunas ocasiones, resultan de considerable riesgo ...

Enforcing environmental law in the Amazon
People and Nature, Volume 8, Issue 7, Page 2281-2294, July 2026.Abstract This article identifies the underlying obstacles to enforcement of laws against environmental crimes such as illegal logging, mining and ranching. With four departments (provinces) from Colombia as case studies, it assesses enforcement of the country's main environmental law, Law 2111, which is one of Latin America's strongest. The article has

Tectonics, Volume 45, Issue 6, June 2026.Abstract This study presents a detailed, geometrical characterization of the central‐western domain of the Jaca‐Pamplona Basin based on a combined interpretation of seismic and surface data and the construction of four serial cross‐sections. For the studied portion of the basin, our results highlight that the basement is notably folded and faulted and ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract The Cretaceous–Eocene island arc of Hispaniola is currently shortened between the Bahamas carbonate platform to the north and the thickened crust of the Caribbean Large Igneous Province (CLIP) to the south. Within this transpressional setting, the 15–22‐km‐thick, ∼100‐km‐wide Beata Ridge (BR), the thickest portion of the CLIP, acts as a ...

Energy development reveals blind spots for ecosystem conservation in the Amazon Basin
Frontiers in Ecology and the Environment, Volume 17, Issue 9, Page 521-529, November 2019., 2019 Energy development – as manifested by the proliferation of hydroelectric dams and increased oil and gas exploration – is a driver of change in Amazonian ecosystems. However, prevailing approaches to Amazonian ecosystem conservation that focus on terrestrial protected areas and Indigenous territories do not offer sufficient insurance against the risks ...

When the Regulatory State Meets Populism: Regulatory Agencies in Mexico
Governance, Volume 39, Issue 2, April 2026.ABSTRACT This paper focuses on two questions: what kind of strategies of de‐institutionalization of the regulatory state have been chosen, and to what extent can they be linked to an explicit ‘populist’ agenda guided by a ‘will of the people’‐ based justification that cuts across different regulatory domains? Applied to the case of Mexico, this article

Satellite‐Observed Changes in Mexico's Offshore Gas Flaring Activity Linked to Oil/Gas Regulations
Geophysical Research Letters, Volume 46, Issue 3, Page 1879-1888, 16 February 2019., 2019 Abstract Gas flaring is a commonly used practice in the oil and gas sector that leads to key air pollutant and greenhouse gas emissions. Here we use multipollutant (NO2, SO2) satellite observations from 2005 to 2017 to quantify gas flaring activity in Mexico's offshore production cluster, which produces ~50–70% of the country's oil and is among the ...
