Scavenging activity of Dermestes maculatus (Coleoptera: Dermestidae) on burned cadaveric tissue
(Springer, 2019-05-29)
The aim of this work was to study the effect that fire exposure in tissues may have on Dermestes maculatus DeGeer (Dermestidae: Dermestini) taphonomic behaviour under controlled conditions. Two different times of fire ...
Traces within traces: holes, pits and galleries in walls and fillings of insect trace fossils in paleosols
(Universidad de Barcelona, 2003-12)
Fossil insect nests with constructed walls (ichnogenera Uruguay ROSELLI 1938, Palmiraichnus ROSELLI 1987, Rosellichnus GENISE and BOWN 1996), as well as fossil brood masses from dung beetles (Monesichnus ROSELLI 1987) often ...
Marks caused by the scavenging activity of Necrobia rufipes (Coleoptera: Cleridae) under laboratory conditions
(Elsevier, 2015-05)
Insects are an important group involved in carrion consumption and are thus of forensic interest. In the laboratory we studied the taphonomic marks that Necrobia rufipes (Cleridae) can produce. Pig trotters were exposed ...
Experimental Evidence in Favor of an Initial One-Electron-Transfer Process in the Heterogeneous Photocatalytic Reduction of Chromium(VI) over TiO 2
(American Chemical Society, 2001-06)
Direct evidence of the involvement of Cr(V) intermediacy in Cr(VI) heterogeneous photocatalytic reduction over TiO2 was obtained by EPR spectroscopy, in the presence and absence of ethylenediaminetetraacetic acid (EDTA). ...
Nitric oxide emission during the reductive heterogeneous photocatalysis of aqueous nitrate with TiO2
(Royal Society of Chemistry, 2015-10)
For the first time, nitric oxide (NO), a precursor of nitrogen dioxide (NO2, a NIOSH-listed atmospheric pollutant), has been found to be one of the final products of the photocatalytic reduction of nitrate in water using ...
Lichen bioerosion on fossil vertebrates from the Cenozoic of Patagonia and Antarctica
(Taylor & Francis, 2011-01)
Different traces occur on fossil bones and teeth coming from the Early Miocene Gaiman Formation (Patagonia, Argentina). Most traces were attributed to the action of terrestrial and marine predators and scavengers. However, ...
Fast photodegradation of Orange II azo dye under visible light irradiation using a semiconducting n-p heterojunction of ZnO nanoparticles/polypyrrole as catalyst
(Springer, 2020-02)
Preparation of innovative nano- and microstructured heterojunctions consisting of two semiconductors for highly efficient p–n photocatalysts has been of growing interest due to their advanced applications. n-type ZnO ...
