### strip:

Filter strip
* are wide strips of vegetation located to intercept overland sheet flows of runoff.
* increase the infiltration of runoff into the soil.

Rumble strip
* are raised lines placed horizontally on a road
  - small indentations or narrow raised strips on the highway or shoulder. * raised lines placed horizontally on a road. They are usually used to tell drivers that they must slow down or stop ahead. The strips make a rumbling sound when a car's tires cross them

### strip | slat:

Louver
* are active thermal control devices used on spacecraft
  - hard to tension uniformly
  - slats
* provide glare-free illumination and precisely direct light to specific work areas.

### stroboscopic effect:

Persistence of vision
* makes the screen appear to be filled with picture.
* refers to a. a filmmaker's desire to have people see a film several times.
* stroboscopic effect.

### stroke:

Hemorrhagic stroke
* are strokes.
* can result in death or severe disability.
* differ from ischemic strokes in that they result from bleeding into the brain.
* is associated with a higher death rate than ischemic stroke.
* is caused by a break in a cerebral artery
  - ruptured blood vessel in the brain
  - bleeding inside the head
  - hemorrhage
  - less common but more frequently deadly than ischemic stroke
  - the most frequently fatal form of stroke
* occur primarily in patients with poorly controlled hypertension.
* occur when a blood vessel in the brain leaks or bursts
  - that supplies the brain ruptures and bleeds
  - small or medium blood vessel inside the brain leaks or bursts
* occur when blood vessels break in the brain
  - burst, causing bleeding within or around the brain
* occurs when a blood vessel bursts inside the brain
  - in the brain ruptures
  - ruptures in or near the brain
  - weakened blood vessel ruptures
* tend to be more serious than ischemic strokes.

Ischaemic stroke
* interrupts the flow of blood to part of the brain.
* is by far the most frequent subtype of acute stroke.

### stroke:

Ischemic stroke
* are ischemia
  - more common than hemorrhagic strokes
  - the more common, accounting for eighty percent of all strokes suffered
  - usually the result of a blood clot that blocks the flow of blood to the brain
* can occur when a blood clot forms in a blood vessel in the brain or neck.
* happen when the blood supply to the brain is interrupted.
* is caused by a blood clot and is the most common type of stroke
  - blocking a brain artery
  - clot or arterial disease blocking blood flow to the brain
  - an interruption of blood flow to the brain
  - more common and occurs when blood flow to the brain is blocked, often by a clot
* is the most common form of stroke and is caused by blood clots
  - threatening complication of vascular disease
  - type caused when blood flow to the brain is blocked
  - treated by removing obstruction and restoring blood flow to the brain
* occur when a blood clot blocks a blood vessel in the brain.
* occurs when an obstruction within a blood vessel blocks blood flow to the brain
  - arteries supplying blood to the brain are blocked by thrombi or emboli
  - clots plug arteries bringing blood to the brain
* predominate over brain hemorrhage.
* result from a blood vessel blockage that impairs the blood flow to the brain.

### strong buffer:

Sodium citrate
* is an alkaliniser used to treat urinary tract infections.
* is used as a flavoring
  - an acidity regulator in food and drinks
* strong buffer.
* white, granular or crystalline powder with a pleasant acid taste.
