Periodontal Considerations and Prosthodontic Rehabilitation in Patients with Special Health Care Needs: Clinical Challenges, Adaptive Treatment Planning and Multidisciplinary Approaches: A Narrative Review

Carolina Naranjo · Hiram Cuevas · Paola Ortega Lopez · Daniela Ibarra · y 2 más

Patients with Special Health Care Needs (SHCN) experience marked oral health disparities that stem from complex medical, developmental, behavioral and functional conditions. Periodontal disease is especially prevalent in this group, driven by impaired oral hygiene, immune dysregulation, neuromuscular limitations, medic...

Airway Microbiome Is Associated with Atherosclerosis in Adults from Southern Caribbean

Diana Mena-Yi · Alejandra Puerto · Sara Mestra · Josefina Zakzuk · y 4 más

Subclinical atherosclerosis (SCA) has been associated with lung function in many populations. Accordingly, those factors involved in respiratory health may contribute to the mechanisms linking pulmonary and cardiovascular disorders. Since the airway microbiome plays a key role in respiratory pathophysiology, microbial...

Evaluation of Direct Cooling Strategies for Hydrogen Refueling Stations

Santiago Laín · Marcos Larrosa

This study investigates the potential for reducing or eliminating conventional pre-cooling requirements in hydrogen refueling stations (HRS) through the integration of turboexpanders, using a combined thermodynamic modeling and Computational Fluid Dynamics (CFD) approach. A key novelty of the present work is the explic...

Fully Native DPL-Based Conductor Sizing Optimization for Distribution Networks in DIgSILENT PowerFactory

Víctor Mario Vélez-Marín · Oscar Danilo Montoya · Jesús C. Hernández

This paper presents a fully native optimization framework, implemented within DIgSILENT PowerFactory, which is aimed at solving the optimal conductor sizing problem (OCSP) in electrical distribution systems under realistic operating conditions. Our methodology integrates a tabu search algorithm (TSA) directly with the...

Applied Statistical Validation of GC–FID Acetaldehyde Determination in Extra-Neutral Alcohol Using Recovery, Relative Bias, and Factorial Analysis of Variance

Juanita Castro-Chica · Diógenes de Jesus Ramirez-Ramirez · Cristian David Correa-Álvarez

Acetaldehyde is routinely monitored in neutral alcohol, but pooled precision summaries can obscure changes in performance across the working range. This study evaluated 446 valid GC–FID verification results obtained by three anonymized analysts on two gas chromatographic systems (GC 8890 and GC 7890B) at 0.6, 2.5, and...
