MRI (magnetic resonance imaging) is a noninvasive diagnostic test that takes detailed images of the soft tissues of the body.Unlike X-rays or CT, images are created by using a magnetic field, radio waves, and a computer.n MRI scan works by using a powerful magnet, radio waves, and a computer to create detailed images. Your body is made up of millions of hydrogen atoms (the human body is 80% water), which are magnetic.
The term âsoft drinkâ is derived from âsoda waterâ, dating as far back as 1798. Joseph Priestly invented carbonated water in 1767, when he first discovered a method of infusing water with carbon dioxide (CO2) by suspending a bowl of water over a vat of fermenting beer in a brewery in Leeds, England.
The soda-acid extinguisher was first patented in 1866 by Francois Carlier of France, which mixed a solution of water and sodium bicarbonate withtartaric acid, producing the propellant CO 2 gas. A soda-acid extinguisher was patented in the U.S. in 1881 by Almon M. Granger. His extinguisher used the reaction between sodium bicarbonate solution and sulfuric acid to expel pressurized water onto a fire. A vial was suspended in the cylinder containing concentrated sulfuric acid.
