neutro-, neuter-, neutr-, neut- +

(Latin: neither of two; neither one nor the other)

neutralist
1. An advocate of neutrality in international affairs.
2. A person who strongly and publicly supports or adheres to a policy of strict neutrality in foreign affairs.
3. Someone who speaks in behalf of or who sticks to a policy or theory of neutralism.
neutrality
1. The state or policy of being neutral; especially, the nonparticipation in war.
2. A situation in which there is no support for either side in a war or a disagreement; uncommitted, impartial.
3. Behavior which does not show strong feelings or strong opinions about issues, situations; apolitical, middle-of-the-road, and nonpartisan.
neutralization
1. Action intended to nullify the effects of some previous action.
2. An action intended to keep a country politically neutral or to exclude it from a possible war.
3. The removal of a threat by killing or destroying it; especially, in a covert operation or military operation.
4. The process of making a solution neutral (pH = 7) by adding a base to an acid solution, or adding an acid to an alkaline (basic) solution; which is also known as neutralization reaction.
5. A chemical reaction in which an acid and a base interact with the formation of a salt.

With strong acids and bases, the essential reaction is the combination of hydrogen ions with hydroxyl ions to form water.

neutralize
1. To counterbalance or to counteract the effect of something.
2. To make something ineffective, especially by removing its ability to act as a threat or obstacle; such as, to destroy a bomb or a threatening military target.

To destroy or to reduce the effectiveness of enemy military personnel and materiel by gunfire, bombing, or any other means.

3. To render a chemical substance as neither an acid nor an alkaline (pH of 7).
4. To nullify the oscillation-producing voltage feedback from the output to the input of an amplifier through tube interelectrode capacitances.

An external feedback path is used to produce at the input a voltage that is equal in magnitude but opposite in phase to that fed back through the interelectrode capacitance.

5. In optics, to place a lens in contact with other lenses of equal and opposite power so that the combination has zero power.
neutralizer
1. That which makes something ineffective by counteracting it or nullifying it.
2. In the military, taking action to put something out of action or to make it incapable of action; such as, using artillery weapons as a neutralizer to make an enemy position ineffective.
neutrally
1. A reference to not being aligned with, supporting, or favoring either side in a war, a dispute, or a contest.
2. Relating to a solution or compound that is neither acidic nor alkaline.
3. Of or relating to a particle, an object, or a system that has neither a positive nor a negative electric charge.
neutron
1. An uncharged elementary particle that has a mass nearly equal to that of the proton and is present in all known atomic nuclei except the hydrogen nucleus.
2. A neutral hadron that is stable in the atomic nucleus but decays into a protron, an electron and an antineutrino with a mean life of 12 minutes outside the nucleus. Neutronics exist in all atomic nuclei except normal hydrogen. Reported in 1932 by James Chadwick.
neutropenia, neutropenic, neutrophilopenia
The presence of abnormally small numbers of neutrophils (mature white blood cells) in the circulating blood of the body.

Neutrophils are white blood cells (WBCs) produced in the bone marrow that ingest bacteria. Neutropenia is sometimes called agranulocytosis or granulocytopenia because neutrophils make up about 60% of white blood cells and have granules inside their cell walls.

Neutropenia is a serious disorder because it makes the body vulnerable to bacterial and fungal infections.

The normal level of neutrophils in human blood varies slightly according to age and race. Infants have lower counts than older children and adults, and African Americans tend to have lower counts than Caucasians or Asians.

neutrosphere
The atmospheric shell from the earth's surface upward in which the atmospheric constituents are, for the most part, electrically neutral.
neutrotaxis
Stimulation of neutrophilic leukocytes by a substance in such a manner that they are either attracted, and move toward it or they are repelled, and move away from it.

In some instances, there is no effect, which is then referred to as indifferent neutrotaxis.

thermal neutrality
A condition of the thermal environment of a homeothermic animal in which its heat production (metabolism) is not increased either by cold stress or by heat stress.
Ubi pugnantia inter se in testamento juberentur, neutrum ratum est.
Where repugnant or inconsistent directions are contained in a will, neither is valid.
