When diagnosed with 3c 4c 5c 6c bulging discs with severe head pain and pain in your neck radiating into shoulders left arm and tingling in your fingers what all can be done is there a pinched nerve?

If the disks are herniated (bulging is another term) the specific nerves causing your problems ARE being pinched/compressed by the disks - that's what happens when you herni (MORE)

What can positrons do?

Positrons are anti-electrons; they're antimatter. There are a couple of sources of positrons, and in our universe, the positron is looking for an electron to combine with so i (MORE)

What happens in the positron emission of silicon-26?

Silicon-26 is a synthetic isotope of silicon; it is a man-made isotope. Additionally, silicon-26 is pretty unstable, and it has a half life of only about 2.234 seconds. This u (MORE)

How does positron emission cause nuclear transmutation?

  It is in beta plus decay that we see the positron emitted from the nucleus. (An electron is emitted in beta minus decay.) Within the nucleus of an unstable atom, a proto (MORE)

Why do positron emission and electron capture have the same effect on a nucleus?

The reason positron emission and electron capture have the same effect on the nucleus of an atom is because the resulting atom undergoes nuclear transformation, and the new el (MORE)

What is the force exerted on the -4 C by the plus 5C charge?

-4c charge can make the exerted force go on another object such as the 5c positive charge. because wen u multiply em' they make a similarity between them such as -4c+5c which (MORE)

How does positron emmission tomography work?

Positron emission tomography (PET) is a nuclear medicine imaging technique which produces a three-dimensional image or picture of functional processes in the body. The system (MORE)
