Constraints on porosity and mass loss in O-star winds from modeling of X-ray emission line profile shapes [PDF]
, 2013 We fit X-ray emission line profiles in high resolution XMM-Newton and Chandra grating spectra of the early O supergiant Zeta Pup with models that include the effects of porosity in the stellar wind.

A mass-loss rate determination for zeta Puppis from the quantitative analysis of X-ray emission line profiles [PDF]
, 2009 We fit every emission line in the high-resolution Chandra grating spectrum of zeta Pup with an empirical line profile model that accounts for the effects of Doppler broadening and attenuation by the bulk wind.

Modelling urban floods using a finite element staggered scheme with porosity and anisotropic resistance [PDF]
, 2018 Artificial porosity models for urban flooding use porosity as a statistical descriptor for the presence of buildings, which are then treated as subgridscale features. Computational efficiency makes porosity models attractive for large-scale applications.

MOLDING PROCEDURE FOR PERVIOUS CONCRETE SPECIMENS BY DENSITY CONTROL
Case Studies in Construction Materials, 2021 Pervious concrete (PC) is a special concrete with the main objective of surface runoff management, due to its hydraulic performance and infiltration capacity. Currently, the standards and guidelines (existing) do not adequately standardize the production

eTropic: electronic journal of studies in the tropics, 2022 This article uses adhesives or what I am calling here ‘sticky matter,’ to illustrate multispecies relationships in Macao, a subtropical coastal region in South China. It focuses primarily on a traditional rammed earth material known as chunambo in Macao

Variations of porosity in calcareous sediments from the Ontong Java Plateau [PDF]
, 1993 Based on index properties measurements made on board the JOIDES Resolution, we studied porosity changes with depth in the fairly homogeneous deep-sea calcareous sediments cored during Ocean Drilling Program Leg 130 on the Ontong Java Plateau.

Comparison of the approaches to assessing the compressibility of the pore space
Записки Горного института, 2022 Integral and differential approaches to determining the volumetric compression of rocks caused by changes in the stress state are considered. Changes in the volume of the pore space of rocks are analyzed with an increase in its all-round compression ...
