Install a set of four-bolt steel main caps over the center two crankshaft mains if you're using a two-bolt-main block. Have the block align bored and have the cylinders bored 0.030-inch over. This overbore isn't so much to buy you more displacement as it is to help enhance airflow to feed the extra cubic inches.
Most commonly used fuel is U235, a naturally occurring radioactive isotope of uranium. Occurs naturally at 0.7% of uranium ore, but must be enriched to 3%. Formed in cylindrical pellets (1.5cm long) and stacked in hollow metal rods (4 m long). About 100 rods are bundled together to make a fuel assembly.
Radioactive isotopes are used to form images of the thyroid, bones, heart, liver, and many other organs. They used also have helped in treating diseased organs and tumors. The most commonly used example of such isotopes is technetium-99, which accounts for 80% of nuclear medicine procedures.he use of radioactive isotopes in medicine involves radionuclide therapy. Cancerous cells can be controlled or even eliminated by irradiating the tumor growth region. Teletherapy, also known as external irradiation is carried out by gamma beams emitted from radioactive cobalt-60 source.
