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 slug is an English and U.S. customary unit of mass. The slug is part of a subset of coherent units known as the gravitational foot-pound-second system, one of several such specialized systems of mechanical units.It is the mass that accelerates by when a force of one pound-force (lbf) is exerted on it. Therefore a slug is about 32.174 05 pounds or 14.593 90 kg.he slug is part of a subset of coherent units known as the gravitational foot-pound-second system, one of several such specialized systems of mechanical units. It is the mass that accelerates by when a force of one pound-force (lbf) is exerted on it.
