The Occurrence Variability of Severe Scintillation and Range Spread F From the Varying Nature of Large‐to‐Meso‐Scale‐Wave‐Structures: Observations and Simulation

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract The occurrence variability on a day‐to‐day basis of severe S4 scintillation and range‐spread F (RSF) which are the manifestations of the most robust dynamical spread F phenomenon in the nighttime equatorial‐low‐latitude ionosphere, remains intriguing to date. The complex nature of large‐to‐meso‐scale‐wave‐structure (LSWS) that results from the

Spatial predictors of landowners' engagement in the restoration of the Brazilian Atlantic Forest

People and Nature, Volume 7, Issue 1, Page 247-264, January 2025.
Abstract Forest restoration can potentially contribute to multiple global sustainable development goals. Yet, little is known about the factors associated with local actors' choice to engage in restoration, limiting the development of effective scaling strategies.

Plant antagonistic facilitation across environmental gradients: a soil‐resource ecosystem engineering model

New Phytologist, Volume 244, Issue 2, Page 670-682, October 2024.
Summary Theory questions the persistence of nonreciprocal interactions in which one plant has a positive net effect on a neighbor that, in return, has a negative net impact on its benefactor – a phenomenon known as antagonistic facilitation. We develop a spatially explicit consumer‐resource model for belowground plant competition between ecosystem ...

Espectroscopia anelástica em ligas de Nb-16% p. Ti

Materials Research, 2003
Átomos de oxigênio, presentes em metais com estrutura cristalina cúbica de corpo centrado, são localizados preferencialmente em sítios octaedrais. Na ausência de uma tensão mecânica externa, estes átomos são distribuídos aleatoriamente.

Nonphotochemical quenching kinetics GWAS in sorghum identifies genes that may play conserved roles in maize and Arabidopsis thaliana photoprotection

The Plant Journal, Volume 119, Issue 6, Page 3000-3014, September 2024.
SUMMARY Photosynthetic organisms must cope with rapid fluctuations in light intensity. Nonphotochemical quenching (NPQ) enables the dissipation of excess light energy as heat under high light conditions, whereas its relaxation under low light maximizes photosynthetic productivity.

Effective diffusivity and convective mass transfer coefficient during the drying of bananas Difusividade efetiva e coeficiente de transferência convectivo de massa durante a secagem de bananas

Engenharia Agrícola, 2012
In this article, a methodology is used for the simultaneous determination of the effective diffusivity and the convective mass transfer coefficient in porous solids, which can be considered as an infinite cylinder during drying.

Integrated water resources management and the land‐water nexus: A South African perspective

World Water Policy, Volume 10, Issue 3, Page 755-779, August 2024.
Abstract As a source of diffuse pollution, land use/land cover (LULC) can have profound impacts on water quality. Accordingly, the importance of managing the land‐water nexus is often emphasized in the rhetoric of Integrated Water Resources Management (IWRM).

Fluxo difusivo de fosfato em solos do Seridó Paraibano

Revista Principia
A difusão é o principal meio de transporte do fósforo (P) no solo e depende de vários fatores, como a interação do P com os componentes da fase sólida, a textura, a mineralogia da fração argila, a umidade, a compactação e a fonte fosfatada. Assim, dada a
