Reproductive biology and pollination of Govenia utriculata: A syrphid fly orchid pollinated through a pollen-deceptive mechanism
(WILEY-BLACKWELL, 2008)
The reproductive biology and pollination mechanisms of Govenia utriculata (Sw.) Lindl. were studied in a mesophytic semideciduous forest at Serra do Japi, south-eastern Brazil. The floral visitors and pollination mechanisms ...
Ironporphyrin immobilized onto montmorillonite as a bimimetical model for azo dye oxidation
(ELSEVIER SCI LTD, 2008)
In this work, we studied the oxidation of the azo dye Disperse orange 3 (DO3) by hydrogen peroxide, catalyzed by 5,10,15, 20-tetrakis(4-N-methylpyridyl)porphyrin iron(III) chloride immobilized onto montmorillonite K10, ...
Vibrisseaceous fungi from the southern hemisphere, including Chlorovibrissea chilensis (Helotiales, incertaesedis) sp. nov.
(Taylor, 2014-06)
The discovery of Chlorovibrissea chilensis sp. nov. expands the geographic distribution of Chlorovibrissea from Australasia to include South America. C. chilensis, phylogenetically distinct from other species in the genus, ...

First report of genus Cosmocercella, Steiner, 1924 (Nematoda: Cosmocercidae) in Amphibians from Argentina
(Helminthological Society of Washington, 2012-01)
This is the first record of the cosmocercid nematode, Cosmocercella minor, in Argentina in the host Phyllomedusa hypochondrialis, the orange-legged Leaf Frog. The species was observed using light and scanning electron ...
Nanoclay as Adsorbent: Evaluation for Removing Dyes Used in the Textile Industry
(Elsevier, 2015-04)
The dyes commonly used in the textile industry have structural resonant valence distribution, within a complex molecule, which determines the color of the dyes. The coloring is produced by chromospheres holding radiation ...
Influence of Chromophore Concentration and Network Structure on the Photoorientation Properties of Crosslinked
(John Wiley & Sons Inc, 2009-03)
An azo prepolymer (TAZ) was synthesized by reaction between Disperse Orange-3 (DO3) and diglycidyl ether of bisphenol A (DGEBA). Selected amounts of TAZ were blended with DGEBA and cured with an aliphatic diamine, either ...
