POCT in the ED â¢ Faster does not always lead to better outcome â¢ Lab tests are rarely the rate limiting factor in ED disposition â¢ Process analysis is the key understanding and improving patient throughput in the ED â¢ Test menu selection is a critical component of the potential application of POCT â¢ Match available tests to disposition decisions
Gravity decreases with altitude as one rises above the Earth's surface because greater altitude means greater distance from the Earth's centre. All other things being equal, an increase in altitude from sea level to 9,000 metres (30,000 ft) causes a weight decrease of about 0.29%.
Gravity acts like a magnet â pulling objects together. What causes gravity is not really known. The Earth has gravity. Gravity holds everything close to this planet. Trees, water, animals, buildings, and the air we breathe are all held here by gravity. All of the planets, their moons, and the stars in the universe have gravity. Even our own bodies have gravity. The Earth's gravity is far stronger than our own so we don't notice the gravity our bodies possess. Gravity is affected by the size and proximity of objects. The Earth and the moon have a stronger pull on each other than the Earth and, say . . . , Jupiter because the Earth and moon are closer to one another.
