Attack of the transplant organ by the immune system.
Non-acceptance of e.g. cargo.
Refusal by an insurance company to underwrite a risk; or denial of a claim by an insurer. (See also: declination.)
When the body tries to get rid of a transplanted organ or tissue by making antibodies. Immunosuppressive drugs help prevent rejection.
In reverse osmosis processes, the degree of removal of dissolved salts from the feed water as it passed through a semi-permeable membrane (also called "salt rejection"); expressed as a percentage of the feed water TDS. (See total dissolved solids.)
In a membrane system is expressed as a percent of the total presence of those contaminants that are larger than the membrane's pore size and are retained by it or repelled by an electrical charge.
The percentage of TDS removed from the feed water. Typically greater than 90% rejection is achieved with reverse osmosis.
In cross flow (membrane) filtration and distillation applications, the prevention by the membrane of the passage of total dissolved solids and other contaminants into the product water.
Total elimination of a particular target or range of targets.
Discrimination prevents signal from unacceptable targets
An indication of target nonacceptance by a null in threshold or broken sound while operating in a discriminate mode.
