Thickness Calculation of Pigment Layers and Gold Leaves Using XRF and MA‐XRF Data
X-Ray Spectrometry, Volume 55, Issue 2, Page 335-348, March/April 2026.ABSTRACT In this work, XRF and MA‐XRF data were used to estimate the thickness of Chromium Oxide (Cr₂O₃) pigment and gold leaf applied over Lead White (2PbCO3.Pb(OH)2). The thickness determination was based on the differential attenuation of the Pb‐Lα and Pb‐Lβ characteristic X‐rays, which allows correlating the overlying material layer with the Pb(Lα ...

“You Are Safe Now”: Migrant Youth Constructions of Safety and Schooling in the U.S.
Anthropology &Education Quarterly, Volume 57, Issue 1, March 2026.ABSTRACT Drawing on multisited ethnographic research with migrant families from Brazil, El Salvador, Guatemala, and Honduras who were detained, separated, or endured prolonged transit due to US immigration policies, we articulate how ideas of “relational safety” are situated in relationships with people, place, and time. Contrasting abundant literature

Child: Care, Health and Development, Volume 52, Issue 2, March 2026.ABSTRACT Objectives This systematic review aims to synthesise the current evidence on risk and protective factors that lead to prolonged screen exposure, and to identify both adverse and positive developmental outcomes associated with that screen exposure in preschool children. Materials and Methods Following PRISMA 2020 guidelines, a systematic search

Genomic Analysis of Taurine and Indicine Ancestry in the Montana Tropical Composite Population
Journal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 273-282, March 2026.ABSTRACT The Montana Tropical cattle, a Taurine and Indicine composite, were developed in Brazil since 1994 and were based on crossing four biological types of cattle: zebu (mainly Nelore), tropical adapted taurine (mainly Senepol and Romosinuano), British taurine (mainly Angus) and continental taurine (as Charolais, Simental and Limousin).

A Comparative Study of Melanocytic Tumours: Linking Portuguese Dogs and Cats to Human Cases
Veterinary and Comparative Oncology, Volume 24, Issue 1, Page 105-120, March 2026.ABSTRACT Melanocytic tumours (MT) occur in both humans and companion animals, presenting an opportunity for comparative oncology research. Thus, this study provides a comprehensive epidemiological analysis comparing MT in Portuguese dogs, cats and humans. Data were obtained from the Portuguese National Cancer Registry (RON) (2011–2021) and Vet‐OncoNet (

Skillful Polar WRF Cloud Modeling of a Warm Winter Atmospheric River at the Antarctic Peninsula
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.Abstract Atmospheric rivers are episodic events that can advect relatively large quantities of moisture to Antarctica, contributing to both disproportionate precipitation and melting events. The Year of Polar Prediction, an international effort to improve weather prediction over the southern polar region, presents an opportunity to study the clouds and

Angewandte Chemie International Edition, Volume 65, Issue 7, 9 February 2026.Photosynthetic microorganisms can be used to perform H2 evolution driven by light. However, a crucial limitationlies in the associated generation of molecular oxygen as a by‐product of photosynthesis, which compromises the activity of the biocatalyst performing H2 production, i.e., the hydrogenase.
