| burns, first degree | A first degree burn is superficial and has similar characteristics to a typical sun burn. The skin is red in colour and sensation is intact. In fact, it is usually somewhat painful. (12 Dec 1998) |
| burns, second degree | Second degree burns look similar to the first degree burns in that it is red and sensation is intact; however, the damage is severe enough to cause blistering of the skin and the pain is usually somewhat more intense. (12 Dec 1998) |
| burns, third degree | In third degree burns the damage has progressed to the point of skin death. The skin is white and without sensation. (12 Dec 1998) |
| 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. (05 Mar 2000) |

| second degree burn | A burn involving the epidermis and dermis and usually forming blisters that may be superficial, or by deep dermal necrosis, followed by epithelial regeneration extending from the skin appendages. Synonym: partial-thickness burn. (05 Mar 2000) |
| degree | 1. A step, stair, or staircase. "By ladders, or else by degree." (Rom. Of R) 2. One of a series of progressive steps upward or downward, in quality, rank, acquirement, and the like; a stage in progression; grade; gradation; as, degrees of vice and virtue; to advance by slow degrees; degree of comparison. 3. The point or step of progression to which a person has arrived; rank or station in life; position. "A dame of high degree." . "A knight is your degree." . "Lord or lady of high degree." 4. Measure of advancement; quality; extent; as, tastes differ in kind as well as in degree. "The degree of excellence which proclaims genius, is different in different times and different places." (Sir. J. Reynolds) 5. Grade or rank to which scholars are admitted by a college or university, in recognition of their attainments; as, the degree of bachelor of arts, master, doctor, etc. In the United States diplomas are usually given as the evidence of a degree conferred. In the humanities the first degree is that of bachelor of arts (B. A. Or A. B); the second that of master of arts (M. A. Or A. M). The degree of bachelor (of arts, science, divinity, law, etc) is conferred upon those who complete a prescribed course of undergraduate study. The first degree in medicine is that of doctor of medicine (M. D). The degrees of master and doctor are sometimes conferred, in course, upon those who have completed certain prescribed postgraduate studies, as doctor of philosophy (Ph. D); but more frequently the degree of doctor is conferred as a complimentary recognition of eminent services in science or letters, or for public services or distinction (as doctor of laws (LL. D) or doctor of divinity (D. D), when they are called honorary degrees. "The youth attained his bachelor's degree, and left the university." (Macaulay) 5. A certain distance or remove in the line of descent, determining the proximity of blood; one remove in the chain of relationship; as, a relation in the third or fourth degree. "In the 11th century an opinion began to gain ground in Italy, that third cousins might marry, being in the seventh degree according to the civil law." (Hallam) 7. <mathematics> Three figures taken together in numeration; thus, 140 is one degree, 222,140 two degrees. 8. <mathematics> State as indicated by sum of exponents; more particularly, the degree of a term is indicated by the sum of the exponents of its literal factors; thus, a^2b^2c is a term of the sixth degree. The degree of a power, or radical, is denoted by its index, that of an equation by the greatest sum of the exponents of the unknown quantities in any term; thus, ax^4 + bx^2 = c, and mx^2y^2 + nyx = p, are both equations of the fourth degree. 9. <mathematics> A 360th part of the circumference of a circle, which part is taken as the principal unit of measure for arcs and angles. The degree is divided into 60 minutes and the minute into 60 seconds. 10. A division, space, or interval, marked on a mathematical or other instrument, as on a thermometer. 11. A line or space of the staff. The short lines and their spaces are added degrees. Accumulation of degrees. <geometry> On the earth, the distance on a meridian between two parallels of latitude whose latitudes differ from each other by one degree. This distance is not the same on different parts of a meridian, on account of the flattened figure of the earth, being 68.702 statute miles at the equator, and 69.396 at the poles. Degree of longitude, the distance on a parallel of latitude between two meridians that make an angle of one degree with each other at the poles a distance which varies as the cosine of the latitude, being at the equator 69.16 statute miles. To a degree, to an extreme; exceedingly; as, mendacious to a degree. "It has been said that Scotsmen . . . Are . . . Grave to a degree on occasions when races more favored by nature are gladsome to excess." (Prof. Wilson) Origin: F. Degre, OF. Degret, fr. LL. Degradare. See Degrade.

| third degree burn | A burn involving destruction of the entire skin; deep third-degree burns extend into subcutaneous fat, muscle, or bone and often cause much scarring. Synonym: full-thickness burn. (05 Mar 2000) |
| 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 end-expiratory pressure | Airway pressure which, at the end of expiration, equals atmospheric pressure. (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) |
| zero-order reaction | A reaction that proceeds at a particular rate independently of the concentration of the reactant or reactants. (05 Mar 2000) |
| zero degree teeth |
artificial teeth which have no cusp angles in relation to the horizontal on their occlusal surfaces.
