Sentence examples for a counting frame from inspiring English sources

The abacus is a counting frame designed to facilitate the process of arithmetic calculation.

The surprising creative re-working, occurs in Luci's action of using the felt bead necklace like a counting frame or abacus.

A counting frame (1612 µm2) was placed randomly on the first counting area and systemically moved through all counting areas until the entire delineated area was sampled.

A counting frame of 10.000 µm2 (Region of Interest; ROI) was superimposed on the calibrated images and cells were counted within this area using the image processing and analysis program ImageTool (UTHSCSA, USA) as described before [73] [75].

Fiber intersects were counted using unbiased, systematic sampling using a 60× objective with a counting frame size of 50 µm×50 µm, grid size of 130 µm×200 µm, and virtual plane separation of 7.0 µm [30].

NeuN-positive cells were counted in all cornu ammonis (CA) fields and dentate gyrus (DG) in 2 sections through the anterior hippocampus and Iba-1 positive cells in the right hemisphere in 4 sections, using stereological principles (Stereo investigator 7, System Inc, Magdeburg, Germany), with a counting frame of 40×40 µm per section for NeuN, and 150×150 µm per section for Iba-1.

The numerical densities were determined: (1) Densities of DAPI-labeled cell nuclei (readout for the cellular density) were determined by counting the numbers of DAPI-stained cell nuclei which were within a counting-frame of 10.000 µm2 (ROI).
