Habitat type and macroinvertebrate assemblages in low order Patagonian streams
(E. Schweizerbart´sche Verlagsbuchhandlung, 2003-12)
Benthic macroinvertebrate community structure was studied with respect to stream habitat type in four low-order Patagonian streams (Argentina). Seven habitat types were sampled during high and low water periods in each ...
A microstructure-level study of monoglycerides oleogels using rheomicroscopy
(The American Oil Chemists' Society, 2017)
Monoglycerides oleogels are semisolid systems containing self-assembled structures formed by crystalline material entrapping liquid oil in a three-dimensional network. The microstructure of the network of these oleogels ...
Intestinal antispasmodic effects of three argentinian plants: Hypericum connatum, Berberis ruscifolia and Cecropia pachystachya: mechanisms of action and comparison with the effects of Brugmansia arborea
