Wikipedia

  1. porous

    Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam). There are many ways to test porosity in a substance or part, such as industrial CT scanning. The term porosity is used in multiple fields including pharmaceutics, ceramics, metallurgy, materials, manufacturing, petrophysics, hydrology, earth sciences, soil mechanics, and engineering.

And we gave our word that if … they needed to leave because there were danger from the Taliban, then we would help them do so.

    Time and again, the Biden administration has refused to take concrete action to quell the worsening border crisis, inviting the cartels and human drug smugglers to take advantage of our porous border, without a border wall, illegal immigrants, coyotes, and bad actors can simply march across our southern border and into the interior. The border wall needs to be built, the funds have been appropriated to continue to build the wall, and yet the Biden Administration outright refuses to do so.

  5. Carlos Soto:
