Estabilidad dimensional en hidrocoloide irreversible posterior a la desinfección con NaClO en dos concentraciones

Revista de la Facultad de Odontología, 2023
La desinfección de las impresiones dentales es un paso fundamental en la práctica clínica para evitar la infección cruzada, por lo tanto, es importante realizarlo de manera correcta debido a las alteraciones dimensionales que puede producir sobre el material de impresión.

Hummingbird interaction niche packing is influenced by species richness and resource availability in the southern tropical Andes

Functional Ecology, Volume 40, Issue 7, Page 2275-2285, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche partitioning is often considered an important mechanism promoting species co‐occurrence in species‐rich communities. As species richness increases, niche partitioning may lead to different niche structures, including increased packing of species niches when the ...

From species lists to interactions: Network structure, not richness, guides seed dispersal management in human‐modified islands

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings show that management strategies can create fundamentally different seed dispersal regimes, even under similar environmental conditions. Anthropogenic diversification reshapes network organisation into distinct structural configurations, rather than consistently enhancing overall cohesion.

Influência da distribuição granulométrica na estabilidade dimensional de placas cerâmicas de base vermelha [PDF]

Cerâmica, 2008
As propriedades do revestimento cerâmico queimado estão intrinsecamente ligadas às características da massa, dentre estas se encontram o tamanho, a distribuição, o formato e o arranjo das partículas. O efeito da distribuição granulométrica de partículas sobre a estabilidade dimensional de placas cerâmicas para revestimentos de base vermelha foi ...

Evolutionary mobility and genetic dynamics of MORFFO genes: shuttling among ancient plant lineages

New Phytologist, Volume 250, Issue 2, Page 1248-1264, April 2026.
Summary Plastid genomes (plastomes) of land plants are characterized by their architectural and genic content stability. However, fern plastomes exhibit unexpected dynamism, characterized by the presence of mobile protein‐coding genes (CDS) – Mobile Open Reading Frames in Fern Organelles (MORFFOs). We investigate the evolutionary dynamics of MORFFOs in

Estudo Comparativo da Estabilidade Dimensional em Diferentes tipos de Materiais de Moldagem

Journal of Health Sciences, 2018
O objetivo foi analisar a estabilidade dimensional de diferentes tipos de materiais de moldagem. Um estudo quantitativo, experimental “in vitro” foi realizado. Foram confeccionados 300 corpos de prova a partir de uma matriz padronizada (n15) nos quais foram avaliados o peso com o auxílio de uma balança de precisão e o volume com um paquímetro digital ...

Institutional Resilience and Energy Security Risks: Comparative Evidence From European Union Member States

World Affairs, Volume 189, Issue 2, Summer 2026.
ABSTRACT In the post‐pandemic period, intensified energy price fluctuations, supply disruptions, and geopolitical tensions have tested national institutional capacities. This study examines the dynamic interaction between energy risks and government effectiveness using annual data from 25 European Union member states over 2008–2023, employing a Panel ...
