A fully coupled particle method for dynamic analysis of saturated soil
(Springer, 2020-10)
Among other numerical issues, it is well known that the finite element method (FEM) lacks objectivity in reproducing high deformation rates due to extreme external actions. In geotechnical applications, the coupling of ...
Steady-state energy optimization and transition assessment in a process of CO2 absorption from natural gas
(Pergamon-Elsevier Science Ltd, 2018-09)
An industrial-scale MDEA-based CO2 absorption process is considered in this work. Natural gas plant of Aguaragüe Argentina is selected to perform the studies of optimization and dynamics. With the steady-state of the process ...
Multi-year GNSS monitoring of atmospheric IWV over Central and South America for climate studies
(Copernicus Publications, 2016-07)
Atmospheric water vapour has been acknowledged as an essential climate variable. Weather prediction and hazard assessment systems benefit from real-time observations, whereas long-term records contribute to climate studies. ...
Thickness-Dependent Reactivity of O2 on Cu Layers Grown on Ru(0001) Surfaces
(American Chemical Society, 2018-07)
The reaction of diatomic molecules on bimetallic surfaces, formed by one to few monolayers of a metal adsorbed on a different metal substrate, is relevant to understand the role of surface strain and substrate chemical ...
Solitary choanoflagellate dynamics and microconfined directed transport
(IOP Publishing, 2020-12-01)
In evolutionary biology, choanoflagellates are broadly investigated as the closest animal ancestors. Under suitable environmental cues, choanoflagellate Salpingoeca rosetta can differentiate into two types of solitary ...
New Silver Nanosensor for Nickel Traces. Part II: Urinary Nickel Determination Associated to Smoking Addiction
(David Publishing Company, 2012-01)
A new fluorescence silver nanosensor assisted by surfactant has been recently synthesized and applied to ultra trace nickel determination. The methodology was validated by the standard addition method and satisfactorily ...
The Chromophore Structures of the Pr States in Plant and Bacterial Phytochromes
(Cell Press, 2007-10)
The resonance Raman spectra of the Pr state of the N-terminal 65-kDa fragment of plant phytochrome phyA have been measured and analyzed in terms of the configuration and conformation of the tetrapyrroles methine bridges. ...
Impact of convective boundary mixing on the TP-AGB
(Oxford University Press, 2020-04)
The treatment of convective boundaries remains an important source of uncertainty within stellar evolution, with drastic implications for the thermally-pulsing stars on the Asymptotic Giant Branch (AGB). Various sources ...
Egg hatching and survival of immature stages of Aedes aegypti (Diptera: Culicidae) under natural temperature conditions during the cold season in Buenos Aires, Argentina
(Entomological Society of America, 2017-01)
In temperate regions, the seasonal dynamics of Aedes aegypti (L) (Diptera: Culicidae) is mainly influenced by temperature. It is assumed that, during the winter season, the population remains as eggs and that the development ...
The diurnal cycle of precipitation over South America represented by five gridded datasets
(John Wiley & Sons Ltd, 2019-08)
A characterization of the diurnal cycle of precipitation (DCP) over the whole South America is still lacking in the literature and the scarcity of sub-daily rain ground measurements limits the data available for analysis ...
