Polyaniline based materials as a method to eliminate haloanisoles in spirits beverages
(2018)In this research, the abilities of two polyaniline-based materials (PANI-EB and PANI-ES) were evaluated as potential fining agents to eliminate 2,4,6-trichloroanisole (TCA) and 2,4,6-tribromoanisole (TBA). The results ...

A new technique in the excavation of ground-nest bee burrows (Hymenoptera: Apoidea)
(2018)Bees have a diversified natural history, thus the methods applied to study such diversity are varied. When it comes to studies of nesting biology, bees which nest in pre-existing cavities have been reasonably well studied ...

Body-size variation across environmental gradients in an ectothermic organism: an intraspecific approach to ecogeographic patterns
(2018)Bergmann's rule states that endothermic species from cool areas tend to have larger body sizes than those from warm areas. Allen's rule maintains that endothermic species from cool environments should have shorter extremities ...

Pollen flow and pollinator sharing among synchronopatric species of Psychotria (Rubiaceae)
(2018)Sympatric plant species that flower at the same time in highly seasonal environments are subject to competitive interference. Many species of the genus Psychotria (Rubiaceae) are sympatric and have an aggregated flowering ...

Thermodynamics sheds light on black hole dynamics
(2018)We propose to unify two a priori distinct aspects of black hole physics: their thermodynamics, and their description as point particles, which is an essential starting point in the post-Newtonian approach to their dynamics. ...
