THE ROLE OF SOIL STRUCTURE ON THE PORE FUNCTIONALITY OF AN ULTISOL
(Chilean Society of Soil Science/Sociedad Chilena de la Ciencia del Suelo, 2010)
The role of sediment humic substances in cu and cr concentrations in the pore water of a typical area of cultivation of sugar cane in São Paulo, Brazil
(2013-08-01)
Humic substances (HS) have an important environmental property, the capacity of complexing metal species. Given this property, studies to understand the behavior of HS with metals are of great relevance. Thus, a study was ...
Anisotropy of pore size classes’ connectivity related to soil structure under no tillage
(Lippincott Williams, 2013-11)
No-tillage (NT) systems have been increasing during the last several decades. Development of a near-surface layer of laminar structure under NT has also been reported. The objectives of this work were to determine whether ...
Occurrence of Cu and Cr in the sedimentary humic substances and pore water from a typical sugar cane cultivation area in São Paulo, Brazil
(2013-08-16)
Purpose: The purpose of this paper is to study the interactions of sedimentary humic substances (SHS) from a sugarcane cultivation area with Cu(II) and Cr(III) and to evaluate the occurrence of these metals in the pore ...

Diffusion of Water and Electrolytes in Mesoporous Silica with a Wide Range of Pore Sizes
(American Chemical Society, 2018-02)
The diffusion of alkaline chlorides (LiCl, KCl, and CsCl) and water in mesoporous silica samples with pore sizes covering the range from micropores (2 nm) up to mesopores larger than 30 nm have been measured by resorting ...
Trace elements distribution in soil, pore water and groundwater in Buenos Aires, Argentina
(Elsevier Science, 2009-03)
The concentration of trace elements in soils, pore water and groundwater was determined in order to evaluate their distribution in the different environmental matrices and their transport through the unsaturated zone to ...
Unsaturated Infinite Slope Stability Considering Surface Flux Conditions
(ASCE-AMER SOC CIVIL ENGINEERS, 2010)
A slope stability model is derived for an infinite slope subjected to unsaturated infiltration flow above a phreatic surface. Closed form steady state solutions are derived for the matric suction and degree of saturation ...
Pore condensation and freezing is responsible for ice formation below water saturation for porous particles
(National Academy of Sciences, 2019-04)
Ice nucleation in the atmosphere influences cloud properties, altering precipitation and the radiative balance, ultimately regulating Earth’s climate. An accepted ice nucleation pathway, known as deposition nucleation, ...
