Positron emission tomography scan (PET scan) Positron emission tomography (PET) is a nuclear imaging technique that creates detailed, computerized pictures of organs and tissues inside the body. A PET scan reveals how the body is functioning and uncovers areas of abnormal metabolic activity. During a PET scan, the patient is first injected with a glucose (sugar) solution that contains a very small amount of radioactive material. The substance is absorbed by the particular organs or tissues being examined.
Kneisler used a hailstone that measured 5.581 inches in diameter and weighed 1.68 lbs (a hailstone that was previously the largest measured in the U.S.) to calculate numbers necessary to estimate the size of the great hailstones in Revelation 16:21. Kneisler also assumed that the great hailstones would weigh 75 lbs in his analysis.
Then multiply by volume of stone needed by the density of the stone â which is 100 pounds per cubic foot. 140.25 feet3 x 100 pounds / foot3 = 14,025 pounds. You can see that we will need about 14,025 pounds of stone or a little over 7 tons.ixed tumbled stones weigh about 0.0618 pounds per cubic inch (or about 107 pounds per cubic foot), and we need 162 cubic inches, so we simply multiplyâ¦. 162 inches3 x 0.0619 pounds/inch3 = 10.01 pounds. Thereâs our answer. We need about 10 pounds of mixed tumbled stones for each planter.
