the Freestyle Stroke The freestyle is also known as the front crawl or the sidestroke. It is used in competitions but there are no real regulations on how it has to be swum. Most swimmers choose to swim front crawl during freestyle competition because it is the fastest technique. For individual freestyle competitions‚ however‚ a swimmer can use any stroke they want‚ but during medley competitions they cannot use the breaststroke‚ butterfly stroke or backstroke. The freestyle stroke involves: coordination

Six-stroke engine The six-stroke engine is a type of internal combustion engine based on the four-stroke engine‚ but with additional complexity intended to make it more efficient and reduce emissions. Two types of six-stroke engine have been developed since the 1990s: In the first approach‚ the engine captures the heat lost from the four-stroke Otto cycle or Diesel cycle and uses it to power an additional power and exhaust stroke of the piston in the same cylinder. Designs use either steam

Summary The acute ischemic stroke (AIS) market is poised for major changes during the forecast window out to 2017. Given the impending patent expiry of Activase/Actilyse‚ in 2015 and 2016 in the US and 5EU respectively‚ the current standard of care for AIS patients is expected to lose its leading position. From 2015 onwards‚ Activase is expected to see declining sales; this is not only attributed to loss of patent protection‚ and the subsequent erosion from potential biosimilar versions‚ but is

Introduction We have heard about two and four stroke engines. Two stroke engines got its name from the fact that the required strokes are completed in one revolution. In short there is one power stroke in one revolution. In the case of four stroke engines the four strokes are completed in two revolutions‚ or there is a power stroke in two revolutions. Then how about a six stroke engine. The name of the engine has nothing to do with the number of revolutions or anything of that sort. This engine

Let’s face it‚ in the eyes of the modern day motocross racer‚ 2 strokes are a thing of the past. But don’t let anyone fool you into thinking that a camshaft equipped bike is superior to the modern day 2 stroke though. The 4 stroke equipped dirt bikes have the upper hand thanks to race rules regarding engine displacement. To help make them competitive they literally doubled the displacement for what is allowed for a 2 stroke. As the 4 stroke evolved and progressed over a few short years it was clear they

STROKE(cerebrovascular accident/Disambiguation) A stroke‚ or cerebrovascular accident (CVA)‚ is the rapid loss of brain function(s) due to disturbance in the blood supply to the brain. This can be due to ischemia (lack of blood flow) caused by blockage (thrombosis‚ arterial embolism)‚ or a hemorrhage. As a result‚ the affected area of the brain cannot function‚ which might result: In an inability to move one or more limbs on one side of the body. Inability to understand or formulate

1. Ronald is experiencing a cerebral vascular accident also known as a CVA or in layman’s terms‚ he is experiencing a stroke. Cerebral vascular accidents are very serious medical emergencies that are life threatening. Stroke is a generalized term that explains injury or death of the brain tissue due to interruption of cerebral blood flow (Bledsoe‚ p.g.197). A stroke occurs when the flow of blood to a part of the brain is stopped completely or significantly reduced. With no oxygen supply from the

a type of stroke that only last a few minutes. They are sometimes called ¡§mini-strokes.¡¨ The term transient is used to describe a condition that lasts only a short amount of time. Ischemic describes an inadequate blood flow. Therefore‚ TIA is a deprivation of blood to the brain for a short period of time. General Information Transient Ischemic Attacks occur in the same way as an ischemic stroke. Both occur when the blood supply to part of the brain is blocked‚ which is why a stroke is known

commonly termed a stroke. It refers to the injury to the brain that occurs when flow of blood to brain tissue is interrupted by a clogged or ruptured artery‚ causing brain tissue to die because of lack of nutrients and oxygen. Causes and symptoms Arterial blood carries oxygen and nutrients to the cells of the body. When arteries are unable to carry out this function due to rupture‚ constriction‚ or obstruction‚ the cells nourished by these arteries die. There are two forms of stroke‚ ischemic‚ which
