Vascular resistance recent results showing the sheath flow surrounding the plug flow in a vessel, the sheath flow size is not neglectible in the real blood flow velocity profile in a vessel. The velocity profile is directly linked to flow resistance in a vessel. The viscosity variations, according to Thurston, are also balanced by the sheath flow size around the plug flow. The secondary regulators of vascular resistance, after vessel radius, is the sheath flow size and its viscosity. Thurston, as well, shows that the resistance R is constant, where, for a defined vessel radius, the value η(δ)/δ is constant in the
What It Is to Burn with boiling liquid. Doherty said they "just wanted some cool imagery". The art direction and design were done by P.R. Brown, who also did the photography with Kris McCaddon. Initial pressings of the album contained a demo version of "What It Is to Burn", produced by Chris Fuderich. It was replaced on later pressings with a re-recorded version, produced by Trombino. These later pressings were available from June onwards. The UK edition, released on June 2, included an acoustic version of "Letters to You" and the demo of "What It Is to Burn" as bonus tracks. Following the album's release,
