A nuclear reaction in which nuclei combine to form more massive nuclei with the simultaneous release of energy.
The specific absorption and re-emission of electromagnetic radiation at characteristic wavelengths by atomic nuclei in a magnetic field. It is abbreviated NMR. The wavelength of the radiation absorbed depends on the type of nucleus, the intensity of the magnetic field, and the local chemical environment in which the nucleus resides. It is the latter effect (called the chemical shift), by which atoms of specific elements in different chemical compounds show a different resonance frequency, which gives rise to the greatest utility of this phenomenon in analyzing the chemical structure of substances. Similar effects of the chemical environment permit the discrimination of different types of living tissue by virtue of their different chemical composition, thus permitting utilization of the phenomenon in medical diagnostic instruments, especially for magnetic resonance imaging.
Of or pertaining to a nucleus; as, the nuclear spindle (see Illust. of Karyokinesis) or the nuclear fibrils of a cell; the nuclear part of a comet, etc.
A scientist specializing in nuclear physics.

The resonance absorption of a gamma ray by a nucleus identical to the nucleus that emitted the gamma ray.
A war in which nuclear weapons are used by both sides. As generally used, the term assumes major use of nuclear weapons by at least two opposing warring states. As of 1999, no nuclear war has occurred.
The warhead of a missile containing an atom bomb or hydrogen bomb.
A weapon of great explosive power, such as an atomic bomb or a hydrogen bomb, which depends for most of its explosive power on the release of energy from within atomic nuclei by a nuclear reaction. A fission weapon or a fusion weapon. The term includes atomic shells for cannon.
a hypothetical lowering of global temperature postulated as the aftermath of a full nuclear war. The mechanism of such an effect depends primarily on the injection into the atmosphere of small solid particles, as soot from burning forests, which reflect sunlight and cause a reduction in solar energy retained by the earth.

A type of molecule found in all living organisms, present mostly in chemically combined form as a component of nucleic acids, and also in smaller amounts in free form, consisting of a pentose sugar bound to a purine or pyrimidine base; two types of nucleoside, ribonucleoside and deoxyribonucleoside, are present. The most common bases present in nucleosides are adenine, cytosine, uracil, guanine, and thymine, and to a lesser extent hypoxanthine and other bases are found. The most commmon ribonucleosides composed from these bases are called adenosine, cytidine, uridine, and guanosine. The forms esterified with orthophosphoric at the 5-position of the pentose are called nucleotides. The nucleotides form the monomer units which are combined into DNA and RNA, which carry the genetic information required for reproduction in all known organisms.
