The ability of a radio receiver to separate a desired signal frequency from others
for columns, the relative affinities of a pair of analytes for a stationary phase under a given set of chromatographic conditions For detectors, the types of compounds which will cause a detector response
refers to a gas detector's ability to select one type of fuel gas from a mixture of fuel gases and other pollutants Most gas detection technologies today are not selective Laser technology offers the potential for selectivity
The ability of a receiver to reject interfering signals close to the desired carrier frequency
used to describe the variability in rate of movement of different ions thru the same ion channel The "height" of the energy barrier of an ion channel's selectivity filter will help determine ion it let thru Often, the term selectivity is not properly defined and can refer to either of the two processes of permeability or conduction The distinction should always be made
Many reactions can potentially occur in any real catalyst systems Selectivity is the measure of the ability of the catalyst to promote desired reactions without affecting those that are not desired
Selectivity refers to application of safeguards measures in a discriminatory manner, against a particular country whose exports have risen and contributed particularly to the "injury "
Selectivity is a measure of the narrowness of a band pass filter The greater the selectivity, the narrower, or more selective, the filter The term is also used to describe the ability of a radio receiver to separate transmitting stations that are close together on the dial
The degree to which a plant or plant part is removed differently from that which is expected by random removal Selectivity is expressed as the ratio of the proportion of a plant or plant part in a diet to all the other herbage
Refers to the percentage of rows in a table that are returned by a query A query is considered highly selective if it returns a very limited number of rows A query is considered to have low selectivity if it returns a high percentage of rows Generally speaking, if a query returns more than 5% of the number of rows in a table, it is considered to have low selectivity
Automated method of designating/screening imported merchandise for examination by a Customs inspector or commodity specialist
The property of a tuned circuit that discriminates between signal voltages of different frequencies
The ability of a type of gear to catch a certain size or kind of fish, compared with its ability to catch other sizes or kinds
The degree of falling off in response of a resonant device with departure from resonance
The ability of the receiver to select the station it is tuned to, from all the others close to it on the dial/display
