Hydropower generation under anthropogenic disturbances: A global review and case studies in France and Colombia.

Paul Hazet · Olivier Evrard · Benjamin Quesada · Anthony Foucher · y 1 más

Hydropower, the global leading renewable energy source (one-sixth of worldwide electricity), is increasingly vulnerable to environmental and anthropogenic pressures. This study assesses their impacts through a systematic review and local scale studies. A systematic review carried out with a PRISMA-based screening of 1,...

Chronic poverty and disability in Latin America: the case of Chile, Colombia and Peru

Mónica Pinilla-Roncancio · Gustavo Cedeño-Ocampo

Use of satellite information and application of assisted learning algorithms for CO2 injection and storage and its implications for groundwater in Colombia

Pedro Romero · Adriana Piña

The successful implementation of Carbon Capture, Utilization, and Storage (CCUS) technologies relies on the rigorous characterization of geological formations to ensure long-term geomechanical stability and containment integrity. In regions governed by complex hydrogeological dynamics, establishing a robust geomechanic...

Finerenone, eplerenone, and spironolactone in heart failure with preserved ejection fraction: a Bayesian network meta-analysis of efficacy and safety

Vitor Bagattoli · Helena Schell dos Santos · Juliana Giorgi · Pedro Gomes Batista · y 3 más

Abstract Aims The comparative effects of mineralocorticoid receptor antagonists (MRAs) in heart failure with preserved ejection fraction (HFpEF) or mildly reduced ejection fraction (HFmrEF) remain uncertain, including potential differences between steroidal MRAs and finerenone. This Bayesian network meta-analysis aimed...

Dimensional Optimization Process of a Boat for Riverine Combat Training Simulation

Carlos Mario Soto Montaño · Aldo Lovo Ayala · Armando Guerrero Mondul · José Escorcia Gutierrez

This work presents the basic design phase for the dimensional optimization of a training boat to be used in a riverine combat simulator prototype for operational training the of Colombian Navy. The prototype system will operate on a motion platform capable of realistically reproducing the dynamic and ergonomic conditio...

Defining the impact of pine cultivation on soil water content in Zapatoca, Santander, using Electrical Resistivity Tomography (ERT).

Katherin Herrera · Rocio Bernal-Olaya · Juan Colegial-Gutierrez

This study assesses the impact of pine tree plantations on soil water content in Zapatoca, northeastern Colombia, using multitemporal electrical resistivity tomography (ERT) combined with laboratory analyses. The research compares four land covers: a native tree forest and three pine species in plantation: Pinus maximi...

Towards a high-granularity methane emissions inventory for Colombia – First in situ measurements of solid waste landfills and wastewater treatment plants emissions

Rodrigo Jimenez · Andres V. Ardila · Luis A. Morales-Rincon · Angela C. Vargas-Burbano · y 5 más

Methane’s comparatively short atmospheric lifetime and low mitigation costs compared to other greenhouse gases enhance its potential for near-term climate action. Both mitigation accounting and climate science require accurate emission inventories. Most emission factors and model parameters have been derived from measu...

GIS-Based Methodologies for the Design of Urban Biomass Energy Generators

Yessica Trujillo Ladino · Javier Rosero Garcia · Juan Galvis

Urban areas require context-specific bioenergy solutions to advance toward circular and sustainable energy systems. In Bogotá, urban pruning and grass-cutting residues constitute a relatively stable biomass stream; however, the absence of district-scale valorization infrastructure leads to their direct disposal in land...

Sensibilidad en estructuras de guías de onda Strip y Rib con material SU-8 en Interferómetro Mach Zehnder

Jhon Jairo Vejar Caballero · Jesús Álvarez Guerrero · Oriana Alexandra López Bustamante · Karla Cecilia Puerto López · y 1 más

Silicon technology, widely used in photonics, is expensive due to the fabrication processes and infrastructure required. In contrast, polymers offer a cheaper and more versatile alternative for the fabrication of photonic devices. Therefore, companies are looking for new technologies and methodologies to develop photon...

Late Holocene climate variability and associated paleoenvironmental changes in northern South America, Colombia

Edward Duarte · Juan Felipe Franco-Gaviria · Jaime Escobar · Alex Correa-Metrio · y 3 más

Sediment records have been widely used to reconstruct Holocene environmental and climate conditions around the world. Despite the climatic sensitivity of northern South America, paleoenvironmental studies remain limited, particularly regarding ecosystem responses to Late Holocene climate fluctuations. Here we present a...
