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 ...

Mobilidade transnacional, dissidência sexual e hibridismo em A confissão de Lúcio, de Mário de Sá-Carneiro (1914)

open access: yesJournal of Lusophone Studies, 2019
In this essay, I examine the uncanny in Mário de Sá-Carneiro's A confissão de Lúcio (1914). Drawing on Sigmund Freud, Julia Kristeva, and Homi Bhabha, I argue that the uncanny plays a crucial role in Sá-Carneiro's exploration of facets of both the queer ...

Seasonal dynamics in terrestrial insect communities after the impact of the Brumadinho tailings dam disaster

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 634-646, May 2026.
Despite severe habitat loss, insect species richness, seasonal fluctuations in richness and temporal β‐diversity did not differ significantly among forests adjacent to the mudflow and reference sites. We found higher wet‐season species richness for ants, bees, butterflies and dung beetles, while termites showed no seasonal change; β‐diversity was ...

Mário de Sá-Carneiro: suicídio ou transfiguração?

open access: yesAnuário de Literatura, 2016
Vivemos uma era de inflação: dinheiro inflacionado, cargos inflados, cartas de recomendação infladas, reputações infladas e ideias infladas. O pós-modernismo, sem designação própria, não passa, para alguns, de uma versão enfatuada do modernismo.

Understanding Fabrication Variability in Core‐Shell Soft Biomaterials Using Stochastic Artificial Intelligence

open access: yesAdvanced Science, Volume 13, Issue 24, 27 April 2026.
Fabrication‐induced variability remains a fundamental limitation in the scalable design of soft biomaterials. In this work, a stochastic machine learning approach based on Gaussian processes modeling is employed to establish quantitative links between biofabrication parameters, material properties, and their intrinsic variability.

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the risk of food poisoning due to the presence of biogenic amines in meals made from chicken meat consumed by children under 3 years of age

open access: yesFood Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Biogenic amines are low molecular weight organic bases that come from the enzymatic decarboxylation of amino acids. They are present in many types of food, with the highest concentrations usually found in fish and their derived products, as well as in beverages and fermented foods of plant, meat and dairy origin.
