Example: "The term 'esr' is unclear and needs further explanation."
Alternatives: "This term is ambiguous" or "This abbreviation is not defined."
Along with morning stiffness and aching, the inflammatory process can be detected by analyzing the patient's erythrocyte sedimentation rate (ESR).

According to another document, the vulnerability exploited by EgotisticalGiraffe was inadvertently fixed when Mozilla removed the E4X library with the vulnerability, and when Tor added that Firefox version into the Tor browser bundle, but NSA were confident that they would be able to find a replacement Firefox exploit that worked against version 17.0 ESR.
Jeffery Ketland (2004) argues in detail that the Newman objection trivialises the Ramsey sentence formulation of ESR.
Similar effects govern the performance of electron spin resonance (ESR), another analytical technique widely used by chemists.
The erythrocyte sedimentation rate (ESR) is the rate at which red blood cells settle in a column of blood in one hour.
The comparison of the two sets of values permits a detailed quantitative test of the microscopic description of the structure of matter in the compounds studied by ESR.
The advent of ESR has marked a new understanding of these substances.
In the ENDOR method, driving an NMR resonance changes the populations of at least one of the energy levels between which an ESR transition is observable, and thus the strong ESR signal is measurably modified.
For instance, the proton NMR frequency in a field of 10 kilogauss is 42.58 megahertz, and in the same field the ESR frequency of a free spin is 28,000 megahertz.
