Sentence examples for specimens often used from inspiring English sources
Unlike the fixed-cantilever, constant-deflection thin specimens, often used to measure fatigue strength of cold spray coatings, the present approach does not considerably reduce the applied stress at the interface compared to the nominal stress and thus represents a more critical and realistic response of the coatings to fatigue loading conditions.
Synthetic bone test specimens are often used in favour of cadaveric specimens, because of their low variance in material properties and availability (when compared to cadaveric specimens), and for the uncontaminated and clean test environment that they provide.
Mechanical testing of cadaveric specimens is often used to quantify bone strength and develop insight for relating in-vivo measures to fracture force.
Tracheal aspirates and bronchoalveolar lavage specimens were more often used to establish the microbiologic diagnosis among patients receiving inappropriate treatment.
An alternate approach often used in specimen studies is a decalcification of the bone matrix.
Mechanical scraping of surfaces is often used for specimen collection and is the method of choice for certain infections, e.g. infectious keratitis (Hall and York 2004).

For solid samples, a Thermal Ionization Mass Spectrometer (TIMS) is often used, e.g. for strontium and neodymium specimens, and generates very precise results.
Faecal samples are not routinely used as specimens for nutritional biomarkers in current studies, whereas coprolites are often used to assess prehistoric diets [ 27], and faecal samples are now used as isotopic markers of diet in ecological studies [ 3].
