Territorios campesinos en el municipio de Paranã (TO): lucha y resistencia de la comunidad Angical

, 2020
Los campesinos, al producir en la tierra, establecen un conjunto de relaciones sociales que tienen sus propias características. En este sentido, la formación socioespacial de una comunidad campesina involucra una serie de relaciones que ocurren con el tiempo, cuyas prácticas campesinas se consolidan y producen nuevos arreglos. Esto ocurre al consolidar

FinTech and Environmental Sustainability: Evidence From Brazil

Sustainable Development, EarlyView.
ABSTRACT This study explores the dynamic interplay between economic growth and environmental sustainability from a FinTech perspective, using Brazil as a case study. While FinTech's contribution to green transformation, sustainable finance, and resource efficiency has gained increasing attention, a notable lack of empirical research remains to assess ...

Incidence of Trypanosoma cruzi infection in two Guatemalan communities.

, 2004
The prevalence of human infection by Trypanosoma cruzi was assessed using an enzyme-linked immunosorbent assay (ELISA) in a serological survey in 1998 of 2 rural communities (SMH and PS) in Guatemala.

On the Interaction of the Photovoltaic Response With Ferroelectric and Magnetic Domains: Magnetoelectric Control of the Photovoltaic Response in BiFeO3 Thin Films

Small Methods, EarlyView.
This study demonstrates tunable photovoltaic responses in pure, polycrystalline BiFeO3 thin films, controlled by external electric and magnetic fields. By aligning ferroelectric domains and leveraging magnetoelectric coupling, the photogeneration is amplified up to seven times.

Influence of Heat Treatment Temperature on Crevice and Pitting Corrosion of UNS S32205 Duplex Stainless Steel

steel research international, EarlyView.
Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

steel research international, EarlyView.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

General formulation for uniform and non‐uniform high‐strength steel slender I‐section beams

Steel Construction, EarlyView.
Abstract The Ayrton–Perry approach is the basis of Eurocode 3 rules for buckling resistance, with distinct curves and imperfection factors depending on section type, steel grade, and other parameters. For generic members – built‐up or not, uniform or not, with complex supports or not – the code allows either the general method (clause 8.3.4 of Eurocode
