The current designs require manual positioning of specimen.
As the applied load was increased, diagonal shear cracks extended both downward to the support and upward to the applied load positions of specimens.
Furthermore, the swelling pressure at different position of specimen was monitored during the infiltration process, and the dry density distributions have also been determined at the end of the tests.
We chose 15° flexion of the elbow, as it made positioning of the specimens in the test bench much easier.
These findings suggest that the positioning of the specimens is an important parameter, which has to be set precisely, in a standardized manner, in order to ensure high measurement reproducibility and a high inter-specimen comparability.
The most important advantages of tissue array technology include increased capacity, negligible damage caused to the original tissue blocks, the precise positioning of tissue specimens and the utility of these tissues in different kinds of molecular analyses.
On examining microscopic preparations from 27 fetuses, they identified two to four terminal vessels penetrating the rectal wall and reaching the submucosa, especially in the posterolateral position (71percentnt of specimens) 17.
Such tasks include the planning of the experiment, the alignment and positioning of the specimen, the least-squares refinement of diffraction spectra, the definition of strain in the sample coordinate system, and its visualization within a 3D model of the specimen.
The capillary is attached to a rotation stage that allows precise positioning of the specimen for recording images from equidistant angles.
Although ultrasonic measurements were correlated to the orientation of the margin, the diameter of the transducer elements (0.635 cm), in addition to the lack of an exact point-by-point matching of transducer position to specimen pathology in this study, most likely resulted in the sampling of tissues of mixed pathologies (e.g., normal breast plus DCIS) in a significant number of measurements.
The fracture positions of these specimens also support above conclusion.
