Air infected with some noxious substance capable of engendering disease; esp., an unhealthy exhalation from certain soils, as marshy or wet lands, producing fevers; miasma.

Originally, the art of managing engines; in its modern and extended sense, the art and science by which the mechanical properties of matter are made useful to man in structures and machines; the occupation and work of an engineer.
n.
A person skilled in the principles and practice of any branch of engineering. See under Engineering, n.
n.
A deviation of the rays of light toward the surface of an opaque body; inflection; diffraction.
v. t.

n.
Structures in civil, military, or naval engineering, as docks, bridges, embankments, trenches, fortifications, and the like; also, the structures and grounds of a manufacturing establishment; as, iron works; locomotive works; gas works.
n.
any preparation used to render an organism immune to some disease, by inducing or increasing the natural immunity mechanisms. Prior to 1995, such preparations usually contained killed organisms of the type for which immunity was desired, and sometimes used live organisms having attenuated virulence. since that date, preparations containing only specific antigenic portions of the pathogenic organism are also used, some of which are prepared by genetic engineering techniques.
n.
An instrument for measuring the diameters of minute particles or fibers, from the size of the colored rings produced by the diffraction of the light in which the objects are viewed.
p. pr. & vb. n.
of Engineer
n.
One of a number of light or dark bands, produced by the interference of light; a diffraction band; -- called also interference fringe.
n.
Same as Diffraction.
n.
The deflection and decomposition of light in passing by the edges of opaque bodies or through narrow slits, causing the appearance of parallel bands or fringes of prismatic colors, as by the action of a grating of fine lines or bars.
n.
A system of close equidistant and parallel lines lines or bars, especially lines ruled on a polished surface, used for producing spectra by diffraction; -- called also diffraction grating.
n.
A piece of DNA, usually circular, functioning as part of the genetic material of a cell, not integrated with the chromosome and replicating independently of the chromosome, but transferred, like the chromosome, to subsequent generations. In bacteria, plasmids often carry the genes for antibiotic resistance; they are exploited in genetic engineering as the vehicles for introduction of extraneous DNA into cells, to alter the genetic makeup of the cell. The cells thus altered may produce desirable proteins which are extracted and used; in the case of genetically altered plant cells, the altered cells may grow into complete plants with changed properties, as for example, increased resistance to disease.
n.
That branch of science, or of engineering, which treats of fluids in motion, especially of water, its action in rivers and canals, the works and machinery for conducting or raising it, its use as a prime mover, and the like.
