Porosity, -porosity and measures [PDF]
Nonlinearity, 2002 We show that given a σ-finite Borel regular measure μ in a metric space X, every σ-porous subset of X of finite measure can be approximated by strongly porous sets. It follows that every σ-porous set is the union of a σ-strongly porous set and a μ-null set.

Investigation of the physical and mechanical properties and durability of pervious concrete: a review [PDF]
Archives of Civil Engineering, 2022 In recent years, the application of pervious concrete (PC) in urban areas has expanded mainly due to its high potential for controlling and guiding surface waters and floods.

An experimental study of the influence of lithology on compaction behaviour of broken waste rock in coal mine backfill [PDF]
Royal Society Open Science, 2019 The research aims to explore the influences of lithology on the compaction behaviours of broken waste rocks. For this purpose, a WAW-1000D servo test machine and a self-made bidirectional loading test system for granular materials were used to conduct ...

Influence of Physical and Chemical Components on the Physical-Mechanical Properties of Ten Brazilian Wood Species [PDF]
Materials Research, 2020 Wood offers a good combination of high strength and low density, but its complete characterization takes a long time. This study aimed to correlate apparent density, chemical component and porosity parameters with the physical and mechanical properties ...

Liquids with permanent porosity [PDF]
Nature, 2015 Porous solids such as zeolites and metal-organic frameworks are useful in molecular separation and in catalysis, but their solid nature can impose limitations. For example, liquid solvents, rather than porous solids, are the most mature technology for post-combustion capture of carbon dioxide because liquid circulation systems are more easily ...

On the porosity of barrier layers [PDF]
Ocean Science, 2009 Abstract. Barrier layers are defined as the layer between the pycnocline and the thermocline when the latter are different as a result of salinity stratification. We present a revisited 2-degree resolution global climatology of monthly mean oceanic Barrier Layer (BL) thickness first proposed by de Boyer Montégut et al. (2007).
