What are atoms made of?

Protons and neutrons come together in the center of the atom to form the nucleus. Electrons orbit the nucleus. These electrons are bound to the nucleus by an electromagnetic force. Protons have a positive charge, while electrons carry a negative charge. Neutrons do not have a charge. Protons and neutrons can be further divided into particles called quarks. Electrons can not be further broken down because they are fundamental particles. Atoms are the basic building blocks of matter. Atoms can join together to form molecules which make up most of life. All elements found on the periodic table ar..

What are some American Heart Association guidelines for CPR?

It is vital not to wait before performing CPR or mistake the sign of a patient gasping for functional breathing, notes CPR Headquarters. Many individuals who undergo cardiac arrest may exhibit abnormal breathing, even if they are still getting air.

How is a while loop used in Perl?

In programming, the while loop is used to iterate a function a certain number of times. This is especially useful in code that uses a lot of variables. Since certain variables might change each time a program runs, the while loop is used to help perform the correct number of operations. The number of operations might not be constant from run to run, but the number can almost always be calculated as some ratio or relationship between variables.\n\nIf a while loop has a condition that is always true, then it loops infinitely. To avoid this, there is always some line of code in the loop that affe..

What are UV tattoos?

UV tattoos, also called blacklight tattoos, are a relatively new concept. Because the potential health concerns are yet unknown, many tattoo artists do not offer this service, writes Karen L. Hudson for About.com. The UV tattoo is usually invisible under normal light, but then shines in various colors when under blacklight or UV light. Many times, only a portion of a visible tattoo has UV effects, such as a black tattoo skull that has UV-tinted eyes. So, when under a UV light in the dark, the colored eyes shine brightly.
