Not all accidental releases of flammable gases and vapours create explosions; most releases do not find an ignition source and of those that do ignite, most of them generate low or moderate overpressure only (deflagrative combustion).However, when certain conditions are satisfied, deflagration to detonation transition (DDT) can occur followed by st
Application of pressure head theory to determine the aerodynamic characteristics of the helicopter main rotor
A method is proposed for calculating main aerodynamic characteristics of the main rotor of the Mi-26 helicopter: a lift, a reactive moment, a required power of Essential Oil Blends the propulsion system, a speed of the inductive air flow, a throttle response coefficient, a speed of the horizontal flight.This method based on the pressure propeller t
Retroverted Uncinate Process: An Anatomic Variation
Considerable attention has been directed toward analysis of paranasal sinus anatomy through coronal plane computerized tomographic (CT) imaging in this age of functional endoscopic sinus surgery.Recently, it has become apparent that anatomic variations are also evident on CT analysis of patients.Subtle anatomic features can now be imaged through CT
Investigation of the Amathillopsidae (Amphipoda, Crustacea), including the description of a new species, reveals a clinging lifestyle in the deep sea worldwide
Amathillopsidae is a widely distributed, but rarely sampled family of deep-sea amphipods.During a recent expedition to the North Atlantic, specimens were filmed clinging to a polychaete tube in situ at abyssal depths by a Remote Operated Vehicle and then sampled for further study.The species was new to Flora science and is described in detail herei
