Detection of Linkage Between Solar and Lunar Cycles and Runoff of the World's Large Rivers

Earth and Space Science, Volume 6, Issue 6, Page 914-930, June 2019., 2019
Abstract It is an ongoing concern that global hydrological cycle can be likely intensified under context of climate change and anthropogenic actions. Here, our results show that the solar and lunar periodic motions (SLPMs) have substantial impact on the runoff of the world's large rivers. We estimate that SLPMs can produce a change of the world's large

Estimating the Potential Production of the Brown Mussel Perna perna (Linnaeus, 1758) Reared in Three Tropical Bays by Different Methods of Condition Indices

Journal of Marine Sciences, Volume 2015, Issue 1, 2015., 2015
Perna perna (Linnaeus, 1758) is the main marine bivalve mussel yielded commercially in Brazil. In spite of this, scientific data is very scarce regarding its productivity in tropical shallow waters. The Condition Index (CI) is used worldwide in mariculture to assess animal health, harvest time, and yield. In this study, the authors used CI results from

The Genus Hyalyris Boisduval, 1870 (Lepidoptera: Nymphalidae) in the Brazilian Atlantic Forest: Systematics, Taxonomy and Conservation

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT The neotropical butterfly tribe Ithomiini (Danainae) comprises about 400 species distributed from Mexico to Northern Argentina, 58 of which occur in the Brazilian Atlantic Forest. Among these are two species assigned to the genus Hyalyris Boisduval, 1870: Hyalyris fiammetta (Hewitson, 1852) and Hyalyris leptalina (C. Felder & R. Felder, 1865).

Multi‐Walled Carbon Nanotube‐Modified Carbon Paste Electrode for Fipronil Detection in Environmental Samples

Electroanalysis, Volume 37, Issue 7, July 2025.
A nanostructured carbon paste sensor modified with 20% multi‐walled carbon nanotubes (MWCNTs) was developed for the detection of Fipronil. The sensor showed enhanced electrochemical performance, with a limit of detection of 0.377 µmol L‐1. It demonstrated good stability, selectivity, and high recovery in water samples, highlighting the potential of ...
