How do soil P tests, plant yield and P acquisition by Lotus tenuis plants reflect the availability of added P from different phosphate sources
(Springer, 2009-01)
The relative effectiveness (RE) of each one of three different sources of P?P in solution (Psol), triple superphosphate (TSP) and phosphate rock (PR)?for reflecting the availability of P in a P-deficient soil were assessed ...
Microstructure, texture and interface integrity in sheets processed by Asymmetric Accumulative Roll-Bonding
(Elsevier Science SA, 2020-01)
Accumulative Roll-Bonding (ARB) and Asymmetric Rolling (AR) techniques were combined to produce ultrafine-grained aluminum sheets with the mechanical characteristics of a Severe Plastic Deformation (SPD) process. Temperature ...
Thermodynamic study of functionalized calix[n]arene and resorcinol[n]arene monolayers spreaded at an aqueous pendant drop
(Springer, 2010-08)
The behavior of insoluble calix[n]arene and resorcinol[n]arene derivatives monolayers were studied through the use of a constant surface Langmuir balance based on Axisymmetric Drop Shape Analysis (ADSA). In each case, a ...
Asthenopodichnium in fossil wood: Different trace makers as indicators of different terrestrial palaeoenvironments
(Elsevier Science, 2012-12)
The ichnospecies Asthenopodichnium xylobiontum comprises U-shaped traces in wood, usually attributed to the activity of mayfly nymphs (Insecta, Ephemeroptera), which indicate the presence of freshwater palaeoenvironments. ...
Hydrogen desorption from a hydride container under different heat exchange conditions
(Elsevier, 2013-10)
The desorption behavior of a hydrogen storage prototype loaded with AB5H6 hydride, whose equilibrium pressure makes it suitable for both feeding a PEM fuel cell and being charged directly from a low pressure water electrolyzer ...

Unveiling new sequestrate Cortinarius species from northern Patagonian Nothofagaceae forests based on molecular and morphological data
(Allen Press Inc., 2019-01)
Because of systematic sampling campaigns in the northern Patagonian Nothofagaceae forests of Argentina, several specimens of sequestrate fungi were collected. Some of those collections showed phylogenetic affinities and ...
Skull ontogeny of the Hyraxes Procavia capensis and Dendrohyrax arboreus (Procaviidae: Hyracoidea)
(Springer, 2018-01)
Extant hyraxes are small, rabbit-sized, herbivorous paenungulates, with a notable feeding mechanism: they crop with the molars instead of the incisors, unlike most modern hoofed mammals. We investigated the postnatal ...
A new oligotrich (Ciliophora, Oligotrichia) from Argentina, with redefinition of Novistrombidium Song and Bradbury
(Elsevier Gmbh, 2019-06)
A new oligotrich similar to Novistrombidium was discovered in plankton samples from an artificial tributary of the Salado River, Buenos Aires province, Argentina, in summer 2010. Propecingulum fistoleramalliei sp. n. has ...
Ecological role of a flower-dwelling predator in a tri-trophic interaction in northwestern Patagonia
(Elsevier Masson, 2019-01)
Flower-dwelling predators may play several ecological roles depending on their effects on the reproductive success of the plants that they use to forage. However, tri-trophic interactions often are context-dependent ...
