| Patient Zero | The individual identified in 1982 by the Centres for Disease Control as responsible for introducing the HIV virus into the U.S. Population. A Canadian citisen, Patient Zero was a homosexual airline steward who claimed to have had as many as 2,500 sexual encounters. CDC epidemiologists located 19 men in Los Angeles, 22 in New York City, and 8 in other cities who had contracted AIDS from contact with Patient Zero, the earliest known cases of the disease in the U.S. Revealed to be Gaetan Dugas, Patient Zero died in 1984 due to AIDS-related illness.

| protein Zero | <protein> The major glycoprotein of peripheral nerve myelin, an integral transmembrane protein, synthesised by Schwann cells (Mw = 28, 500). (18 Nov 1997) |
| zero | Origin: F. Zero, from Ar. Cafrun, cifrun, empty, a cipher. Cf. Cipher. 1. <mathematics> A cipher; nothing; naught. 2. The point from which the graduation of a scale, as of a thermometer, commences. Zero in the Centigrade, or Celsius thermometer, and in the Reaumur thermometer, is at the point at which water congeals. The zero of the Fahrenheit thermometer is fixed at the point at which the mercury stands when immersed in a mixture of snow and common salt. In Wedgwood's pyrometer, the zero corresponds with 1077 deg on the Fahrenheit scale. 3. The lowest point; the point of exhaustion; as, his patience had nearly reached zero. Absolute zero. See Absolute. <physics> Zero method, a method of comparing, or measuring, forces, electric currents, etc, by so opposing them that the pointer of an indicating apparatus, or the needle of a galvanometer, remains at, or is brought to, zero, as contrasted with methods in which the deflection is observed directly; called also null method. Zero point, the point indicating zero, or the commencement of a scale or reckoning. Source: Websters Dictionary (01 Mar 1998) |
| zero degree teeth | Prosthetic teeth having no cusp angles in relation to the horizontal. (05 Mar 2000) |

| zero energy thermonuclear assembly | <radiobiology> A British fusion device in which scientists observed fusion neutrons in 1958. They were erroneously considered to be thermonuclear (coming from particles with a Maxwellian velocity distribution) and were a cause for the initial optimism that fusion energy would be easy. They were actually due to electromagnetic acceleration during a plasma instability, an effect which cannot be scaled up to produce useful energy. (09 Oct 1997) |
| zero gravity | A physical state existing in space or at a time in flight when the centrifugal thrust of a parabolic glide or turn exactly counteracts the force of gravity. (05 Mar 2000) |

| absolute | 1. Loosed from any limitation or condition; uncontrolled; unrestricted; unconditional; as, absolute authority, monarchy, sovereignty, an absolute promise or command; absolute power; an absolute monarch. 2. Complete in itself; perfect; consummate; faultless; as, absolute perfection; absolute beauty. "So absolute she seems, And in herself complete." (Milton) 3. Viewed apart from modifying influences or without comparison with other objects; actual; real; opposed to relative and comparative; as, absolute motion; absolute time or space. Absolute rights and duties are such as pertain to man in a state of nature as contradistinguished from relative rights and duties, or such as pertain to him in his social relations. 4. Loosed from, or unconnected by, dependence on any other being; self-existent; self-sufficing. In this sense God is called the Absolute by the Theist. The term is also applied by the Pantheist to the universe, or the total of all existence, as only capable of relations in its parts to each other and to the whole, and as dependent for its existence and its phenomena on its mutually depending forces and their laws. 5. Capable of being thought or conceived by itself alone; unconditioned; non-relative. It is in dispute among philosopher whether the term, in this sense, is not applied to a mere logical fiction or abstraction, or whether the absolute, as thus defined, can be known, as a reality, by the human intellect. "To Cusa we can indeed articulately trace, word and thing, the recent philosophy of the absolute." (Sir W. Hamilton) 6. Positive; clear; certain; not doubtful. "I am absolute 't was very Cloten." (Shak) 7. Authoritative; peremptory. "The peddler stopped, and tapped her on the head, With absolute forefinger, brown and ringed." (Mrs. Browning) 8. <chemistry> Pure; unmixed; as, absolute alcohol. 9. Not immediately dependent on the other parts of the sentence in government; as, the case absolute. See Ablative absolute, under Ablative. <geometry> Absolute curvature, the sum of the optic and eccentric equations. <physics> Absolute space, space considered without relation to material limits or objects. Absolute terms. <mathematics> The be ginning, or zero point, in the scale of absolute temperature. It is equivalent to -273 deg centigrade or -459.4 deg Fahrenheit. Synonym: Positive, peremptory, certain, unconditional, unlimited, unrestricted, unqualified, arbitrary, despotic, autocratic. Origin: L. Absolutus, p. P. Of absolvere: cf. F. Absolu. See Absolve. <geometry> In a plane, the two imaginary circular points at infinity; in space of three dimensions, the imaginary circle at infinity. Source: Websters Dictionary (01 Mar 1998) |

| absolute CD4 count | The number of helper T-lymphocytes in a cubic millimeter of blood. With HIV, the absolute CD4 count declines as the infection progresses. The absolute CD4 count is frequently used to monitor the extent of immune suppression in persons with HIV. Also called a T4 count. (12 Dec 1998) |

| absolute zero |
The zero point of the Kelvin temperature scale, of fundamental significance in thermodynamics and statistical mechanics. It is the linearly extrapolated temperature at which the volume of an ideal gas at constant pressure would vanish. All real gases become liquid or solid at sufficiently low temperatures and maintain a finite volume. Absolute zero on the Kelvin scale corresponds to -273.15
