Filter means material placed in the useful beam to preferentially absorb selected radiations.
Topsoil means a varying depth (up to 300 mm) of the soil profile irrespective of the fertility, appearance, structure, agricultural potential, fertility and composition of the soil;
Fluoroscopic imaging assembly means a subsystem in which X-ray photons produce a visual image. It includes the image receptor(s) such as the image intensifier and spot-film device, electrical interlocks, if any, and structural material providing linkage between the image receptor and diagnostic source assembly.
Valve means a device used to control the flow of water in the irrigation system.
Disinfection means a process which inactivates pathogenic organisms in water by chemical oxidants or equivalent agents.
Laser means any device excepting a Class 1 device which can be made to produce or amplify electromagnetic radiation in the wave length range from 100 nanometres to 1 millimetre primarily by the process of controlled stimulated emission.
Assembly means the Assembly of Heads of State and Government of the African Union;
Fluoroscopy means a technique for generating x-ray images and presenting them simultaneously and continuously as visible images. This term has the same meaning as the term "radioscopy" in the standards of the International Electrotechnical Commission.
Disinfect means to eliminate virtually all germs from inanimate surfaces through the use of chemicals or physical agents (e.g., heat). In the child care environment, a solution of ¼ cup household liquid chlorine bleach added to one gallon of water (or one tablespoon bleach to one quart water) and prepared fresh daily is an effective disinfectant for environmental surfaces and other objects. A weaker solution of 1 tablespoon bleach to 1 gallon of cool water is effective for use on toys, eating utensils, etc. Commercial products may also be used.
Sensor means any measurement device that is not part of the vehicle itself but installed to determine parameters other than the concentration of gaseous and particle pollutants and the exhaust mass flow.
Calibration means the determination of (1) the response or reading of an instrument relative to a series of known radiation values over the range of the instrument, or (2) the strength of a source of radiation relative to a standard.
Calibration gas means a gas mixture used to calibrate gas analysers.
Modules means the Base Modules and Extended Modules.
Disinfectant means any oxidant, including but not limited to chlorine, chlorine dioxide, chloramines, and ozone added to water in any part of the treatment or distribution process, that is intended to kill or inactivate pathogenic microorganisms.
Fluid means material or substance which flows or moves whether in a semisolid, liquid, sludge, gas, or any other form or state.
Radionuclide means a radioactive element or a radioactive isotope.
Interconnector means equipment used to link the electricity system of the State to electricity systems outside of the State;
Isolation means a behavior management technique in which a student is placed alone in an enclosed space from which the student is not prevented from leaving.
Microorganisms (1 2) means bacteria, viruses, mycoplasms, rickettsiae, chlamydiae or fungi, whether natural, enhanced or modified, either in the form of "isolated live cultures" or as material including living material which has been deliberately inoculated or contaminated with such cultures.
Biomass means the biodegradable fraction of products, waste and residues from biological origin from agriculture (including vegetal and animal substances), forestry and related industries including fisheries and aquaculture, as well as the biodegradable fraction of industrial and municipal waste;
Outputs means the goods or services that are produced by an entity or other person;
medium voltage means the set of nominal voltage levels that lie above low voltage and below high voltage in the range of 1 kV to 44 kV;
voltage means the root-mean-square value of electrical potential between two conductors.
Diameter means the diameter of the stem of a tree measured outside the bark at a specified point of measurement.
Backpressure means a pressure (caused by a pump, elevated tank or piping, boiler, or other means) on the consumer's side of the service connection that is greater than the pressure provided by the public water system and which may cause backflow.
water meter means any apparatus for measuring or showing the volume of water supplied to, or of effluent discharged from any premises;
