The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine.It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion chamber.
Stroke side refers to the port side of the boat, which is on the left-hand side of a cox facing forwards, but on the right-hand side of a rower facing backwards. The usage derives from the tradition of having the stroke rower's oar be on the port side of the boat.
The term apoplectic stroke is an archaic, nonspecific term, for a cerebrovascular accident accompanied by haemorrhage or haemorrhagic stroke. [252] Martin Luther was described as having an apoplectic stroke that deprived him of his speech shortly before his death in 1546.
An engine is described as oversquare or short-stroke if its cylinders have a greater bore diameter than its stroke length, giving a bore/stroke ratio greater than 1:1. An oversquare engine allows for more and larger valves in the head of the cylinder, higher possible rpm by lowering maximum piston speed, and lower crank stress due to the lower ...
The trudgen is a swimming stroke sometimes known as the racing stroke, or the East Indian stroke. It is named after the English swimmer John Trudgen (1852–1902) [1] and evolved out of sidestroke. [2] One swims mostly upon one side, making an overhand movement, lifting the arms alternately out of the water.
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
The front crawl is a very technical stroke that varies based on the swimmers physique, conditioning, and context. Possible context factors include: competition type, water conditions, and the swimmer's goal. The starting position for front crawl is known as the "streamline" position.
The term 'freestyle stroke' is sometimes used as a synonym for 'front crawl', [3] as front crawl is the fastest surface swimming stroke. [4] It is now the most common stroke used in freestyle competitions. [5] The first Olympics held open water swimming events, but after a few Olympics, closed water swimming was introduced.
