Let's cut thru this cloud of confusion, shall we? In historical warfare, opposing armies would build "Strongholds". A stronghold is a fortified position from which an army could launch offensive strikes or retreat to for defense. A typical example would be a walled city and/or a tower in such

They were probably both guilty of ignorance of what the reaction actually was/is and its potential although Papp had an idea. Unfortunately more injury may result until the reaction(s) are nailed down. There is a reason Plasmerg/Rohners maintain Lexan bullet proof glass around their devices, they

Abd, I size pressure safety relief devices all the time. Typically you select a PSV relief orifice size to handle the maximum instantaneous relief flow required to keep the vessel with 10% of its ASME design pressure. You usually do not let the device/vessel crack or explode. In deflagration ev

Call it the bioassay method of measuring reaction effects. The unit of exposure, the Papp. Lifetime exposure should be limited to a few millipapps. They would use mice for monitoring, but the animal rights people threatened to sue, so former Nature editors were retained. After all, they had
