The Trophic state of Patagonian Argentinean lakes and its relationship with depth distribution in sediment Phosphorus
(Univ Tehran, 2014)
The parameters used to determine the trophic state of a water body are: total phosphorus (TP), transparency (Secchi disk depth) and chlorophyll a. However, these parameters show strong seasonal fluctuations which may hinder ...
Pore structure description of mortars containing ground granulated blast-furnace slag by mercury intrusion porosimetry and dynamic vapour sorption
(Elsevier, 2017-08)
The description of the pore structure is a key aspect when studying the durability of cement-based materials. Many techniques have been developed over the years in order to describe the actual complex microstructure of ...
Water filling of hydrophilic nanopores
(American Institute of Physics, 2010-07)
Molecular dynamics simulations of water in cylindrical hydrophilic pores with diameters of 1.5 and 3 nm were performed to explore the phase behavior and the nucleation dynamics of the confined fluid as a function of the ...
Computational and experimental pore-scale studies of a carbonate rock sample
(2019-12-01)
Carbonate rocks host several large water and hydrocarbon reservoirs worldwide, some of them highly heterogeneous involving complex pore systems. Pre-salt reservoirs in the Santos Basin off the south-east coast of Brazil, ...
Pore size evolution during sintering of ceramic oxides
(1990-12-01)
This paper reviews the influence of particle size distribution, agglomerates, rearrangement, sintering atmospheres and impurities on the pore evolution of some commonly studied oxides. These factors largely affect sintering ...
Assessing the long-term effects of zero-tillage on the macroporosity of Brazilian soils using X-ray Computed Tomography
(Elsevier B.V., 2019-03-01)
Zero-tillage (ZT) is being increasingly adopted globally as a conservationist management system due to the environmental and agronomic benefits it provides. However, there remains little information on the tillage effect ...
Molecular Dynamics Simulations of Water Confined in Calcite Slit Pores: An NMR Spin Relaxation and Hydrogen Bond Analysis
(American Chemical Society, 2017-03)
We study water confined in calcite (104) slit pores from 6 to 1 nm by molecular dynamics. By determining NMR parameters combined with hydrogen bond network analysis, we provide an important contribution to the understanding ...
Effect of water flow and sampling volume on the functional characterization of pores in an UltisolEfecto del flujo de agua y el volumen de muestreo sobre la funcionalidad de los poros de un Ultisol
(Facultad de Ciencias Agrarias. Universidad Austral de Chile, 2016)
Nitrogen sediment fluxes in an upwelling system off central Chile (Concepción Bay and adjacent shelf) during the 1997-1998 El Niño
(Sociedad de Biología de Chile, 2004)
Role of confinement and surface affinity on filling mechanisms and sorption hysteresis of water in nanopores
(American Chemical Society, 2012-01)
The liquid-vapor transition in cylindrical pores is studied as a function of pore size and hydrophilicity through molecular dynamics simulations with the mW coarse-grained model of water. We identify two distinct filling ...
