This is a cross section of an oak (Quercus) stem. Note the production of vessel tubes in the spring to produce a ring-porous growth pattern.
Common deficiencies include porous foundations, broken main drain pipes, substandard renovations, leaning brick walls, and old roofs.

These stalactites are caused by a somewhat different process.
'Tubular lava stalactites are common in many lava tubes and have a concentric tubular shape, are (initially) hollow, and range in diameter from .4 to 1 cm. They are formed by "segregations extruded by expanding gas into cave passages" (Allred & Allred, 1998) as the lava tube cools. In the cooling walls of the cave, some minerals solidify first, forming a coarse, porous matrix. Boiling causes gases to force the remaining segregated liguid material out of the walls, forming tubular lava stalactites. Growth rings are found on the skin of the stalactites, each ring formed from dripping.'

Mantec’s porous ceramic tiles are arranged either in a grid to create a fluidised bed, or in series as a fluidised conveyor for transporting powder from one location to another. Another application is to mount the tiles on the side of powder silos to aid flow and prevent solidification.
Air or gas fed into a compartment or plenum chamber beneath the tiles can only escape by way of the ceramic tiles into the powder above. When velocities are high enough this induces fluidisation. In most cases no more than local fluidisation is necessary to bring about movement in the powder.

“Digital technologies permeate our lives and make the walls of the built environment increasingly porous, no longer the hard boundary they once were when it comes to decisions about privacy. Data profiling, aggregation, analysis, and sharing are broad and hidden, making it harder than ever to constrain the flow of data about us.” Nissenbaum and Varnelis 2010).
The use of CCTV camera’s is an example of an archive that brings the realms of the private and public together, as well as issues of authority and control. Does walking though a shopping centre or park mean you give permission for your actions to be recorded? Or is this just part of living in a high-density area in western society? The answers to these questions will vary according to the person, but the fact is that they exist. Some cameras are more visible than others, however what isn’t always visible is who is behind the camera. Who gets to view the footage? An extension of this is the fact that anyone with a camera enabled phone, can now perform this same exercise and possibly not be under the same rules or regulations that businesses or surveillance companies are when dealing with footage. The aggregation and flow of data mentioned above, can also be seen in discussions of shopping centres potentially using your Wi-Fi connection and security footage to track your shopping habits.
