It may result from infec- tion, obstruction, severe irritation, or faulty absorption of material through the intestinal walls. A specific type of inflammation of un- known cause involving the small and large intestines is known as regional ileitis, regional enteritis, or Crohn's disease. The advanced stage is marked by hardening, thickening, and ulceration of parts of the bowel lining. An obstruction may cause the development of a fistula. A common symptom of ileitis is pain in the lower right quadrant of the abdomen or around the umbilicus. Other symptoms in- clude loss of appetite, loss of weight, anemia, and diarrhea, which may alternate with peri- ods of constipation. ileus Intestinal obstruction, especially failure of peristalsis. The condition frequently accom- panies peritonitis and usually results from disturbances in neural stimulation of the bowel. iliac crest The lateral, superior rim of the coxal bone. iliac spine A projection from the coxal bone at the ante- rior portion of the iliac crest. iliocristale height The vertical distance from the floor or other reference surface to the highest point of the iliac crest in the midaxillary plane.

Expressed as: illuminance The amount of light falling on a surface. Il- luminance is expressed in units of foot- candles or lux. illuminance category An alphabetic character, ranging from A through H, representing illumination ranges for various types of work such that the further the letter is from A, the brighter the light. illuminance meter A device, composed of a photodetector, filter, and electronic circuitry, for measuring the lu- minous flux incident on a plane. illuminance threshold That lowest luminance level which the eye or other image sensor is capable of detecting, given a specified luminance contrast, position within the field of view, dark adaptation, flicker rate, source dimensions, and color. illuminant Any light source or combination of flight sources. illuminant A A standard CIE illuminant corresponding to a typical tungsten filament incandescent lamp. illuminant B A standard CIE illuminant corresponding to direct sunlight. illuminant C A standard CIE illuminant corresponding to average daylight. illuminant D A series of standard CIE illuminants corre- sponding to a daylight which measures be- yond the normal visible spectrum. illuminate To distribute or provide light to an area or region. illumination The density of light flux incident upon a sur- face. illusion A perceptual misinterpretation of a stimulus.

IMC See instrument meteorological conditions. immaterial evidence Evidence which lacks probative weight and is unlikely to influence the tribunal in resolving I IR = N o. of illnesses x 200,000 N o. of man-hours worked ©2000 CRC Press LLC the issue before it. Such evidence is com- monly objected to by opposing counsel, and disallowed by the court. immaterial facts Those which are not essential to the right of action or defense. immaterial issue In pleading, an issue taken on an immaterial point; that is, a point not proper to decide the action. immediate cause The last of a series or chain of causes tending to a given result, and which, of itself, and without the intervention of any further cause, directly produces the result or event. A cause may be immediate in this sense, and yet not "proximate," and, conversely, the proximate cause (that which directly and efficiently brings about the result) may not be immedi- ate. The familiar illustration is that of a drunken man falling into the water and drowning. His intoxication is considered the proximate cause of his death, if it can be said that he would not have fallen into the water when sober; but the immediate cause of death is suffocation by drowning. See also proxi- mate cause. immediate danger The definition of "immediate danger" as part of the humanitarian doctrine contemplates that there be some inexorable circumstance, situa- tion, or agency bearing down on the plaintiff with reasonable probability of danger prior to the negligent act of the defendant. immediately Aviation.

For example, some materials such as hydro- gen fluoride gas and cadmium vapor may produce immediate transient effects that, even if severe, may pass without medical attention, but are followed by sudden, possibly fatal collapse 12-72 hours after exposure. The vic- tim "feels normal" after recovery from tran- sient effects until collapse. Such materials in hazardous quantities are considered to be "immediately" dangerous to life or health. immersion foot That damage to the skin, blood, vessels, and nerves of the feet resulting from prolonged exposure to water at temperatures between freezing and approximately 60°F. imminent danger Any conditions or practices in a place of em- ployment which are such that danger exists which could reasonably be expected to cause death or serious physical harm immediately or before the imminence of such danger can be eliminated. imminent hazard (1) General.

Such a risk to health or the environment shall be considered imminent if it is shown that the manufacture, processing, distribution in commerce, use, or disposal of the chemical substance or mixture, or that any combination of such activities, is likely to re- sult in such injury to health or the environ- ment. immiscible Not capable of being uniformly mixed or blended. ©2000 CRC Press LLC immune Not affected or responsive.
