It was first mentioned about 1540 in Italy as an instrument with both ascending and descending bores contained in a single piece of maple or pear wood.
The ISS 11A is instrumented with both passive and active dosimetric devices.

DRUGS [ 39] and MedMaIDE [ 41], which both use patients' own medications, are the only instruments with evidence of both inter-rater and test-retest reliability, although this needs to be confirmed by researchers other than the instruments' developers.
Since then, new instruments such as the FACT have been developed to augment measurements such as linear analogue scales; and studies using both measures now report positive changes in both instruments with anaemia correction (Glaspy et al, 1997; Demetri et al, 1998).
The evening owed much to its conductor, Harry Bicket, a young Englishman who mixed old instruments with new and kept both parties interested and alert.
The same trend was observed in other sample set data from both instruments, with the λmaxSoret from the Hitachi spectrophotometer slightly higher than the BioTek microplate reader (data not shown).
A single iteration of artifact removal was used on both instruments with 17% spatial averaging.
Known-groups validity was good in both instruments, with PPAC scores differentiating across grades of dyspnoea, stable from exacerbated patients at baseline and tertiles of physical activity levels (using variables not included in the PPAC scoring, such as intensity) (online supplementary table E9).
