FAST (stroke) FAST (stroke) FAST is an acronym used as a mnemonic to help detect and enhance responsiveness to the needs of a person having a stroke. The acronym stands for Facial drooping, Arm weakness, Speech difficulties and Time to call emergency services. The FAST was developed in the UK in 1998 by a group of stroke physicians, ambulance personnel, and an emergency department physician and was designed to be an integral part of a training package for ambulance staff. The FAST was created to expedite administration of intravenous tissue plasminogen activator to patients within 3 hours of acute stroke symptom onset.
Simple chemical reacting system Simple chemical reacting system The simple chemical reacting system (SCRS) is one of the combustion models for computational fluid dynamics. This model helps us to determine the process of combustion which is a vital phenomenon used in many engineering applications like aircraft engines, internal combustion engines, rocket engines, industrial furnaces, and power station combustors. The simple chemical reacting system (SCRS) refers the global nature of the combustion process considering only the final species concentrations. The detailed kinetics of the process is generally neglected and it postulates that combustion does proceed via a global one-step without intermediates. Infinitely fast chemical reaction
