Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

PARAMETRIC STUDY OF THE INFLUENCE OF WIND ON THE DESIGN OF STEEL TUBULAR TOWERS WITH DIFFERENT GEOMETRIES ACCORDING TO THE EUROCODES

open access: yesce/papers, Volume 9, Issue 1, Page 374-383, April 2026.
Abstract The geometries of metallic tubular towers directly influence the interaction between wind action and the structural response of the tower itself. Analyzing these configurations and understanding how this interaction occurs is fundamental for proper structural design.

Commuting Conditions of the k-th Cho operator with the structure Jacobi operator of real hypersurfaces in complex space forms

open access: yesOpen Mathematics, 2015
In this paper three dimensional real hypersurfaces in non-flat complex space forms whose k-th Cho operator with respect to the structure vector field ξ commutes with the structure Jacobi operator are classified.

An elementary proof of MinVol(Rn) = 0 for n > 3

open access: yesAnais da Academia Brasileira de Ciências, 2008
In this paper, we give an elementary proof of the result that the minimal volumes of R³ and R4 are zero. The approach is to construct a sequence of explicit complete metrics on them such that the sectional curvatures are bounded in absolute value by 1 ...

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): II. Solute Concentrations and Flux Dynamics

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy‐derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over
