Consistent and non-consistent deformations of gravitational theories

open access: yesJournal of High Energy Physics, 2022
We study the internally abelianized version of a range of gravitational theories, written in connection tetrad form, and study the possible interaction terms that can be added to them in a consistent way. We do this for 2+1 and 3+1 dimensional models. In

Multi‐Scale Characterization of PLA Composites With Natural‐Based Reinforcements: From Filament to 3D‐Printed Parts

open access: yesPolymer Composites, EarlyView.
Thermal, microstructural, and mechanical characterization of 3D‐printed PLA composite parts. ABSTRACT To address plastic waste and agricultural residue underutilization, this study evaluates the thermal (DSC and FTIR), microstructural (SEM), and mechanical behavior of polylactic acid (PLA) reinforced with flax fibers and olive pit particles, processed ...

The importance of integrating herbarium records into conservation plans: a case study on Honduran ferns and lycophytes

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Herbarium collections are powerful, yet underutilized, tools for global biodiversity conservation and protected area management. By integrating digitized herbarium records with existing biodiversity data, previously unknown plant species were uncovered, exposing critical gaps in conservation knowledge.
