Cerebral Ischemia. Cerebral ischemia or brain ischemia, is a condition that occurs when there isnât enough blood flow to the brain to meet metabolic demand. This leads to limited oxygen supply or cerebral hypoxia and leads to the death of brain tissue, cerebral infarction, or ischemic stroke.erebral ischemia or brain ischemia, is a condition that occurs when there isnât enough blood flow to the brain to meet metabolic demand.
The slug is the unit of mass in the US common system of units, where the pound is the unit of force. The pound is therefore the unit of weight since weight is defined as the force of gravity on an object.hile the pound force and pound weight are the widely used units for commerce in the United States, their use is strongly discouraged in scientific work. The standard units for most of scientific work are the SI units. A newton can be seen to be the force required to accelerate 1 kg of mass at 1 m/s 2.
The blob is the inch version of the slug (1 blob = 1 lb f Â·s 2 /in = 12 slugs) or equivalent to 175.126 kg. This unit is also called slinch (a portmanteau of the words slug and inch).Similar terms include slugette, and a snail.o name has yet been given to the unit of mass and, in fact, as we have developed the theory of dynamics no name is necessary. Whenever the mass, m, appears in our formulae, we substitute the ratio of the convenient force-acceleration pair (w/g), and measure the mass in lbs. per ft./sec.2 or in grams per cm./sec.2.
