Factores asociados al consumo de prendas de segunda mano en estudiantes universitarios colombianos

Campo Elías López-Rodríguez · Adriana Paola Cáceres Saavedra · Cristian Rincón Sánchez · Nathaly Alexandra Rubio Casanova

Este artículo analiza el comportamiento de los factores que inciden en el consumo de prendas de vestir de segunda mano por estudiantes universitarios colombianos. Desde una metodología cuantitativa, descriptiva y causal con una solución factorial y un modelo de ecuaciones estructurales, se determina que la actitud, la...

Agronomic Performance and Quality of SM2828-28, the First Industrial Cassava Variety Suitable for Extended Harvest in the Humid and Dry Caribbean of Colombia

Hernando Araujo-Vasquez · Amparo Rosero · Carina Cordero · Adriana Tofiño · y 10 más

Cassava is a crop of major socioeconomic and cultural importance in Colombia. One of the main challenges is production seasonality, driven by climatic conditions that constrain planting and harvesting periods. Currently, cultivated varieties exhibit a substantial reduction in root dry matter content (DMC) following the...

Temporal Spectral Analysis of Late-Time Error in a Physics-Informed Neural Network Solution of the One-Dimensional Advection–Diffusion Equation

David Díaz-León · Santiago Lain · Diego Garzón-Alvarado · Carlos Duque-Daza

Persistent late-time variation can remain in physics-informed neural network (PINN) solutions after the governing transient has effectively decayed, while conventional error norms do not reveal whether this variation has a systematic temporal–frequency structure. This study develops an offline temporal–spectral diagnos...

Quantifying the Photoelectrochemically Active Surface Area for Oxygen Evolution Metal Oxide Photoelectrocatalysts

Camilo A. Mesa · Shababa Selim · Andreas Kafizas · Yi Wen · y 11 más

Abstract Nanostructuring is established as a photoelectrode performance enhancing route for solar-driven catalytic processes. However, it is often unclear to what extent the increase in photoelectrode physical surface area directly results in a commensurate increase in photoelectrochemically active surface area. While...

Revisión sistemática de las barreras curriculares para la integración del ODS 15 en educación básica primaria

Helmuth Andrés Mariño Poveda · William Orlando Alvarez Araque · Hilda Lucia Jimenez Orozco

La incorporación curricular del ODS 15 en educación básica primaria posee limitaciones estructurales que no se han examinado sistemáticamente por la bibliografía más reciente en el tema. La presente revisión sistemática presenta las barreras que dificultan su implementación en términos educativos a nivel mundial, anali...

Effect of a bioformulation with native Bacillus subtilis and Bacillus thuringiensis strains on the control of Fusarium oxysporum and the rhizosphere microbiome of strawberry (Fragaria × ananassa)

Iván Darío Otero Ramírez · Sandra Magally Sánchez Trujillo · Iván Enrique Paz Narvaez · José Luis Hoyos Concha

Introduction Strawberry ( Fragaria × ananassa ) is an economically important fruit crop whose production has increased substantially in recent years. However, its productivity is severely affected by a wide range of pathogens, including Fusarium oxysporum , the causal agent of wilt. Although chemical control remains wi...

Clinical and metabolic evolution of a dog with diabetes mellitus and hypothyroidism: Dietary and endocrine correlation

Laura Vargas · Julieth Bernal‐Niño · Ximena Vargas · Giselle Bonilla Correa

Abstract The coexistence of diabetes mellitus (DM) and hypothyroidism in dogs represents a complex clinical challenge due to interactions between metabolic and hypothalamic–pituitary–thyroid axes. This case report describes the clinical, endocrine and metabolic evolution of a male Siberian Husky diagnosed with concurre...

Ghost Roads as Hidden Drivers of Landscape Connectivity Loss in the Colombian Andes–Amazon Corridor

Jairo Andrés Sánchez Camacho · Paulo J. Murillo-Sandoval · Camilo Andrés Correa-Ayram

Abstract Context. The expansion of informal and unmapped roads (“ghost roads”) is an underestimated driver of landscape transformation in tropical forest frontiers. In the Andean–Amazon transition belt of Colombia, these roads facilitate deforestation, land-use change, and disrupt ecological connectivity, yet they are...

Sustainable Synthesis of Faujasite-Type Zeolites Synthesized from Rice Husk for Hg2+ Removal from Aqueous Solutions: Adsorption Performance, Mechanistic Insights, and Environmental Safety Assessment

Naren Bocanegra · Marcela Paredes-Laverde · Nancy Acelas · Ximena Carolina Pulido · y 2 más

Rice husk, an abundant agro-industrial by-product rich in SiO2, represents a promising precursor for the sustainable synthesis of zeolites. In this study, rice husk ash was used to synthesize faujasite-type X and faujasite-type Y, and their performance for Hg2+ removal from aqueous solutions was comparatively evaluated...
