Theoretical analysis of the effect of isotropy on the effective diffusion coefficient in the porous and agglomerated phase of the electrodes of a PEMFC

Scientific Reports
In polymer membrane fuel cells (PEMFC), the pore microstructure and the effective diffusion coefficient ( $$D_{eff}$$ D eff ) of the catalytic layer have a significant impact on the overall performance of the fuel cell. In this work, numerical methods to

Simulation of Marine Towing Cable Dynamics Using a Finite Elements Method

Journal of Marine Science and Engineering, 2020
A numerical model to study the towing maneuver for floating and submerged bodies has been developed. The proposed model is based on the dynamic study of a catenary line moving between two bodies, one body with imposed motion, and the other free to move ...

Ecological divergence in the silver moss Bryum argenteum: developmental, ontogenetic and life‐history trait variations across contrasting tropical ecosystems

Plant Biology, EarlyView.
Ecotypes of the cosmopolitan moss Bryum argenteum differ markedly in growth, reproductive timing, and allocation across contrasting tropical ecosystems. These patterns reveal strong environment‐ and sex‐dependent life‐history strategies, highlighting the species as a model for studying ecological divergence in bryophytes.

Vegetation species mapping in a coastal-dune ecosystem using high resolution satellite imagery

GIScience & Remote Sensing, 2019
Vegetation mapping is a priority when managing natural protected areas. In this context, very high resolution satellite remote sensing data can be fundamental in providing accurate vegetation cartography at species level.

Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, EarlyView.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Characterization of Goat Milk Fermented With Streptococcus thermophilus, Limosilactobacillus mucosae CNPC007 and Inulin With Addition of Cereus jamacaru

Applied Research, Volume 5, Issue 3, June 2026.
Limosilactobacillus mucosae maintained viability above 7 log CFU/g during storage of the fermented goat milk with inulin and Cereus jamacaru jam and survived over 4 log CFU/g during the in vitro gastrointestinal simulation. This jam enriched the total phenolic content of the fermented milk that achieved overall acceptability scores close to or above 7.

Taxonomic Updates of Thismia pseudomelanomitra (Thismiaceae) Reveal an Old Acquaintance From the Ecuadorian Amazon

Feddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT The Amazon Basin is home to the world's greatest terrestrial biodiversity, but many plant groups remain poorly studied. One example is the mycoheterotrophic genus Thismia (Thismiaceae), which is notable for its highly specialized floral morphology and ephemeral life cycles, making it difficult to detect in the field and limiting its ...
