Visual Behavior in Inline Speed Skating: An Eye‐Tracking Evaluation for Performance Analysis
This study analyzed oculomotor behavior (fixations and saccades) in 19 competitive inline speed skaters (5 males, 14 females; aged 10–26 years) from the Aragonese Skating Federation (Spain), comparing high‐performance (N1) and intermediate (N2) groups ...

The Reactive Extrusion Cationization of Starches as a Novel Physicochemical Surface Modification Method. [PDF]
Native starches from different botanical sources were cationized by reactive extrusion using 3% glycidyltrimethylammonium chloride (GTAC). The process, performed under controlled thermal zones, promoted the incorporation of quaternary ammonium groups onto the starch backbone.

Thermodynamics of spherically symmetric black holes in scale-dependent gravity
In this work we extend the first law of thermodynamics to spherically symmetric black hole solutions in the context of scale-dependent gravity. After deriving generalized expressions for both the entropy and energy due to the spatial variation of the ...
