Coachâs wardrobes have always fascinated me. Take high profile coaches like Bill Self, the Kansas coach, Rick Pitino, the womanizing coach at Louisville or John Calipari, the master coach of the ACT test at Memphis. They look like they were dressed by GQ.
Applied or liquid membrane - Spray applied membranes, cold-fluid-applied membranes, and hot-applied membranes are types of membranes applied by melting and then fusing a rubber, bitumen, or elastomer layer onto the surface to be waterproofed. Liquid membranes have grown in popularity for horizontal applications. Polyurethane elastomers are the most common material composition for a fluid-applied elastomer membrane. However, bitumen and other epoxy-modified spray-applied membranes are also available.
Permeability is conferred by two classes of membrane proteins, pumps and channels. Pumps use a source of free energy such as ATP or light to drive the thermodynamically uphill transport of ions or molecules. Pump action is an example of active transport. Channels, in contrast, enable ions to flow rapidly through membranes in a downhill direction. Channel action illustrates passive transport, or facilitated diffusion. Pumps are energy transducers in that they convert one form of free energy into another.
