RF-Sputtered ZnO Nano-Coatings on Polyamide Thin-Film Composite Membranes for Tuned Nanofiltration Selectivity

Catalina Vargas · Daniel A. Palacio · Jesús Ramírez · Eduardo Pérez-Tijerina · y 7 más

Water stress is intensifying worldwide, increasing the need for efficient desalination and water purification technologies. Although commercial nanofiltration membranes such as NF90 exhibit high separation performance, their transport properties remain governed by permeability–selectivity trade-offs, and their surface...

Modeling Uncertainty of Renewable Energy in Microgrid Dispatch Using Scenario-Based Risk-Aware Optimization

David O. Briceño · Diana S. López · Sergio R. Rivera

This paper presents a probabilistic and risk-aware framework for microgrid dispatch under renewable generation. In this way, solar irradiance is modeled using a log-normal distribution, on other hand, wind speed follows a Rayleigh distribution. We used a combined multi-regime wind turbine power curve for the eolic part...

Pandemic policy and the care economy: A comparative analysis of care-sensitive social protection in Colombia and Costa Rica

Kayla Alexandra Benjamin · Natalia Ramírez Bustamante · Jeremy Veillard · Sara Allin

Abstract A growing body of literature has reported on the gendered impact of COVID-19. Unemployment and income loss are two consequences of the pandemic that disproportionately impacted women. Studies have shown that these consequences are associated with the rise in unpaid care work (UCW) following the implementation...

Introduction Malaria is a significant public health problem in Colombia. Over the past two decades, environmental changes, internal migration, and gold mining expansion have been linked to variations in transmission dynamics, highlighting the need for updated epidemiological analyses. Objective To describe the epidemio...

Clinical characteristics and real-world survival in acral melanoma: experience from a comprehensive cancer center in Latin America

Diego Gómez-Abreo · Michael Steven Villabona Díaz · Nathalia Andrea Olarte-Licht · Lady Katerine Aldana Galvis · y 4 más

Background Acral melanoma represents a biologically distinct and clinically aggressive melanoma subtype disproportionately affecting non-Caucasian populations. Evidence from low- and middle-income countries remains limited, and the real-world impact of modern immunotherapy in these patients is not well characterized. O...

Mechanical and Microstructural Comparison of Improved Sand with Guar Gum and Cement

Jair de Jesús Arrieta Baldovino · Luis Carlos Suárez López · Jesús Alberto Alcalá Vergara · Yamid E. Nunez de la Rosa

Research on sustainable alternatives to conventional soil stabilization has promoted the use of natural biopolymers as partial substitutes for cementitious binders. This study presents a mechanical and microstructural comparison between poorly graded Colombian sand stabilized with guar gum (GG) and Type III Portland ce...
