Polynomial Equation

Aerosol that is produced when the pneumatic force of a high velocity stream of air breaks up a specified room-temperature liquid into droplets. A solid particle aerosol may also be generated by pneumatic force for some situations, such as generation of discrete-particle counter (DPC) calibration aerosol. ISO 14644-3.

The location where the water delivered from the water distribution system, is actually used.

An Index entry in the directory of a disk (or other storage medium) that identifies the space in the disk in which an electronic document or piece of electronic data resides, thereby preventing that space from being overwritten by other data. In most case, when an electronic document is “deleted” the pointer is changed to a form that allows the document to be overwritten, but the document is not actually erased.

Any substance which when taken into the body in a single dose of 1.0 gm. or less, is injurious to health or dangerous to life.

In female animals, the products of a meiotic division that do not develop into an ovum. The first polar body comprises one of the two products of meiosis I, and it may not go through meiosis II. The second polar body comprises one of the two products of meiosis II.

A solvent for molecules that have permanent electric dipoles.

The observed differentiation of an organism, tissue or cell into parts having opposed or contrasted properties or form.

An intermediate high gloss or polished finish for use where a semi-finished polished surface is required for subsequent finishing operations following fabrication, or as a final finish with fine abrasive compound.

High purity water after it has undergone a second treatment step. Ultrapure water usually undergoes two or more treatment steps. More economical pretreatment processes (e. g., reverse osmosis) are used to remove all but a very small fraction of the impurities. Highly efficient polishing processes (e. g., mixed-bed deionization) are used to remove the impurities that remain.

Smoothing metal surfaces, often to a high luster, by rubbing the surface with a fine abrasive, usually contained in a cloth or other soft lap. Results in microscopic flow of some surface metal together with actual removal of a small amount of surface metal.

In water purification systems ̶ The final treatment stage(s) of the purification system.

Transfer of pollen from anther to stigma in the process of fertilization in angiosperms; transfer of pollen from male to female cone in the process of fertilization in gymnosperms.

A technique a CPU can use to learn if a peripheral device is ready to receive data or to send data. In this method each device is checked or polled in-turn to determine if that device needs service. The device must wait until it is polled in order to send or receive data. This method is useful if the device's data can wait for a period of time before being processed, since each device must await its turn in the polling scheme before it will be serviced by the processor.

A substance or condition that contaminates air, water, or soil. Pollutants can be artificial substances, such as pesticides and PCBs, or naturally occurring substances, such as oil or carbon dioxide, that occur in harmful concentrations in a given environment.

A high molecular-weight gel substance (known to be a neurotoxin) that is used in chromatographic or electrophoretic separations.

A method for separating nucleic acid or protein molecules according to their molecular size. The molecules migrate through the inert gel matrix under the influence of an electric field. In the case of protein PAGE, detergents such as sodium dodecyl sulphate (SDS) are often added to ensure that all molecules have a uniform charge. Secondary structure can often lead to the anomalous migration of molecules. Therefore it is common to denature protein samples by boiling them prior to PAGE. In the case of nucleic acids, denaturing agents such as formamide, urea or methyl mercuric hydroxide are often incorporated into the gel itself, which may also be run at high temperature. PAGE is used to separate the products of DNA-sequencing reactions and the gels employed are highly denaturing, since molecules differing in size by a single nucleotide must be resolved.
