Anticipating cosmetic emulsion stability using a novel multi‐analytical approach

open access: yesInternational Journal of Cosmetic Science, EarlyView.
A novel combination of granulometry, turbidimetry and rheology enables early detection of cosmetic emulsion instability—reducing assessment time from 30 to 8 days. This rapid method distinguishes stable from unstable emulsions under identical conditions, offering a powerful tool for formulation screening and industrial quality control.

A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

open access: yesJournal of Fish Biology, EarlyView.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Random walk with heavy tail and negative drift conditioned by its minimum and final values

open access: yes, 2013
We consider random walks with finite second moment which drifts to $-\infty$ and have heavy tail. We focus on the events when the minimum and the final value of this walk belong to some compact set. We first specify the associated probability.

Are integrative systematic tools efficient toward unraveling species diversity with the genus Jania (Corallinaceae, Rhodophyta)?

open access: yesJournal of Phycology, EarlyView.
Abstract The articulated genus Jania currently comprises 54 accepted species, making it the fourth most speciose genus among corallines, following Lithophyllum, Amphiroa, and Lithothamnion. Unlike these other genera, Jania is relatively easy to identify at a generic rank. However, morpho‐anatomical characters are insufficiently discriminant for species

Comparative evaluation of the attractiveness of new polyethylene screens versus West African tiny target for the control of tsetse flies

open access: yesMedical and Veterinary Entomology, EarlyView.
The material has no significant difference in captures (non‐shiny cotton‐polyester screens vs. the shiny polyethylene screens), but the vertical screen attracted significantly more G. tachinoides for each type of material. Full white horizontal screen was significantly lower than the reference WATT.
