Vapor intrusion in soils with multimodal pore-size distribution [PDF]

open access: yesE3S Web of Conferences, 2016
The Johnson and Ettinger [1] model and its extensions are at this time the most widely used algorithms for estimating subsurface vapor intrusion into buildings (API [2]). The functions which describe capillary pressure curves are utilized in quantitative

Short-term changes in soil pore size distribution: Impact of land use. [PDF]

open access: yesSoil Tillage Res, 2020
Changes in land use affect the pore size distribution (PSD) of the soil, and hence important soil functions such as gas exchange, water availability and plant growth.

Yield stress fluids method to determine the pore size distribution of a porous medium [PDF]

open access: yes, 2014
In this paper a new method is presented in order to determine the pore size distribution in a porous medium. This original technique uses the rheological properties of some non-Newtonian yield stress fluids flowing through the porous sample.

A solid with a hierarchical tetramodal micro-meso-macro pore size distribution [PDF]

open access: yes, 2013
Porous solids have an important role in addressing some of the major energy-related problems facing society. Here we describe a porous solid, alpha-MnO2, with a hierarchical tetramodal pore size distribution spanning the micro-, meso-and macro pore range,

Combining nuclear magnetic resonance and rate-controlled porosimetry to probe the pore-throat structure of tight sandstones

open access: yesPetroleum Exploration and Development, 2016
Rate-controlled porosimetry (RCP), nuclear magnetic resonance (NMR) and micro CT tests were conducted on five tight sandstone samples, the results were compared to reveal the limitations of RCP in determining the pore size distribution (PSD) and pore to ...

Proposal of concept for structural modelling of hybrid beams

open access: yesStudia Geotechnica et Mechanica, 2022
Investigation on the behaviour of a hybrid beam is presented. Hybrid beam stands for an element with hybrid cross sections. This means sections that consist of steel and concrete parts, connected together with composite dowels, and both are considered ...
