The engine pressure ratio (EPR) is the total pressure ratio across a jet engine, measured as the ratio of the total pressure at the exit of the propelling nozzle divided by the total pressure at the entry to the compressor. [1] Jet engines use either EPR or compressor/fan RPM as an indicator of thrust. [2]
The journal was first published, under the title Journal of Aviation Medicine [3] in 1930. In 1959 the title changed to Aerospace Medicine, [4] was renamed Aviation, Space, and Environmental Medicine in 1975, [5] and acquired its current name in 2015. It is often referred to as "the blue journal" by its subscribers.
The Aerospace Medical Association (AsMA) is the largest professional organization in the fields of aviation, space, and environmental medicine. The AsMA membership includes aerospace and hyperbaric medical specialists, scientists, flight nurses , physiologists , and researchers from all over the world.
The terms EHR, electronic patient record (EPR) and EMR have often been used interchangeably, but differences between the models are now being defined. The electronic health record (EHR) is a more longitudinal collection of the electronic health information of individual patients or populations.
eHealth describes healthcare services which are supported by digital processes, communication or technology such as electronic prescribing, Telehealth, or Electronic Health Records (EHRs). The term "eHealth" originated in the 1990s [ 1 ] , initially conceived as "Internet medicine," but has since evolved to have a broader range of technologies ...
Civil Aerospace Medical Institute (CAMI) is the medical certification, education, research, and occupational medicine wing of the Office of Aerospace Medicine (AAM) under the auspices of the Federal Aviation Administration Office of Aviation Safety. The Institute's primary goal is to enhance aviation safety. [1] [2]
But EPR had to cut its dividend during the pandemic. The big culprit was its movie theater exposure, as movie chains weren't in a particularly strong state entering the global health crisis.
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei. EPR spectroscopy is particularly ...
