Sunshine Duration in Brazil From Meteosat (1983–2020): Climatology, Variability and Long‐Term Trends

open access: yesInternational Journal of Climatology, Volume 46, Issue 6, May 2026.
Using nearly four decades of Meteosat satellite data (1983–2020), this study presents a country‐wide climatology of sunshine duration (SDU) in Brazil. The results reveal marked regional contrasts, dominant modes of variability, and significant long‐term trends, providing new information on the most relevant meteorological systems that influence SDU and

Do Policy Capacities Matter for Federal Policy Design? Evidence From the Implementation of Three Social Policies in Brazil

open access: yesPublic Administration and Development, Volume 46, Issue 2, Page 179-196, May 2026.
ABSTRACT Bringing together the literature on policy design, policy capacity and policy making in multilevel systems, this paper argues that the effectiveness of policy design in federal countries depends, ceteris paribus, on the adequacy of federal and local policy capacities.

Poly(Hydroxybutyrate‐Co‐Hydroxyvalerate)/Thermoplastic Starch Blends for Application in Biodegradable Mulch Films

open access: yesPolymer Engineering &Science, Volume 66, Issue 5, Page 3751-3765, May 2026.
Poly(hydroxybutyrate‐co‐hydroxyvalerate)/thermoplastic starch blends, produced by melt processing, showed improvements in mechanical properties and water vapor transmission barrier performance, which can help control excessive water evaporation from the soil, thus contributing to pH and moisture regulation.

Soybean yield performance in oxisols with varying morphological and physicochemical characteristics

open access: yesSoil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Soybean (Glycine max (L.) Merril) yield in tropical high‐altitude regions is strongly influenced by soil physical and chemical attributes, particularly in highly weathered oxisols, where variability among suborders may affect crop performance.

Non‐Destructive Inspection of TCPs Using Pulse‐Echo Ultrasound and X‐Ray Microcomputed Tomography Techniques

open access: yesX-Ray Spectrometry, Volume 55, Issue 3, Page 443-453, May/June 2026.
ABSTRACT Thermoplastic composite pipes (TCPs) have potential applications in offshore oil and gas industries because of their strength, lack of corrosion, and flexibility. Designed for fluid transportation in high‐pressure and high‐temperature environments, manufacturing defects and operational loads can compromise their performance.

Landscape features predict broad‐scale seed rain patterns across fragments of the Brazilian Atlantic Forest

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Along with precipitation, forest cover emerges as a fundamental driver of alpha and beta diversity in the seed rain. This highlights the role of habitat amount at the landscape level over patch‐level features, like patch size, for seed dispersal. However, increased seed density can be related to higher dispersal rates in forest borders.
