The Impact Of Time-dependent Matrix-fracture Fluid Transfer In Upscaling Match Procedures
(Elsevier Science BVAmsterdam, 2016)
Hierarchy of factors driving N2O emissions in non-tilled soils under different crops
(Wiley, 2013-08)
Nitrous oxide (N2O) is emitted to the atmosphere as a by-product of nitrification and denitrification by soil microbial processes. Differences in climate, soil and management regulate these processes, causing N2O emissions ...
Validation of gas diffusivity models with Chilean soil samples
(Springer, 2020)
This study compares the goodness of fit of 10 empirical models used to predict gas diffusivity (DpD0-1) with experimental data obtained from Chilean soil samples from different soil management practices. Nine sites under ...
Soils act as sinks or sources of CH4 depending on air-filled porosity in sclerophyllous ecosystems in semiarid central Chile
(2018)
Carbon dioxide (CO2) and methane (CH4) are greenhouse gases (GHG), which sustained increase in the atmosphere contribute to global warming and climate change. The GHG fluxes of soils are strongly controlled by water content, ...
Tolerance to partial and complete submergence in the forage legume Melilotus siculus: An evaluation of 15 accessions for petiole hyponastic response and gas-filled spaces, leaf hydrophobicity and gas films, and root phellem
(Oxford University Press, 2019-01)
• Background and Aims: Submergence is a severe stress for most plants. Melilotus siculus is a waterlogging- (i.e. root zone hypoxia) tolerant annual forage legume, but data were lacking for the effects of partial and full ...
Determination of particle density and porosity in foods and porous materials with high moisture content

Flow evolution of a metallic slurry during thixoextrusion of an automotive valve
(2004-12-01)
The aim of this work is to characterize a metallic slurry (Al-4.5%Cu) flow during thixoforming of an automotive valve. The necessary globular structure was obtained by first inoculating the alloy with TIBAL (5%Ti, 1%B, Al ...
Compactação do solo causada pelo tráfego de máquinas na colheita de madeira de Eucalyptus grandis Hill ex Maiden
(Universidade Estadual Paulista (Unesp), 2003-05-23)
Foram avaliados os efeitos causados ao solo pelo tráfego de máquinas florestais de corte e baldeio de madeira, com ênfase à compactação, em floresta de Eucalyptus grandis Hill ex Maiden, de 91 meses de idade, através do ...
Análise da influência do empacotamento dos agregados na porosidade do concreto
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2014-09-09)
The resistance to external actions which the concrete element is subject is related to the porosity of concrete. One of the factors that interfere in resistance is the water / cement ratio, where the higher the water / ...
