For indenting the tissue, we utilized 8 μm thick cylindrical SU-8 tip.
The functional equation method was employed to develop a contact mechanics model for indenting a viscoelastic material with adhesion.
The standard samples of fused silica with elastic modulus of 73 GPa and Poisson's ratio of 0.17 were used for indenter calibration allowing reliable load and displacement resolution at the level of 10 nN and 0.1 nm, respectively.
However, for the sampled theses, whenever the programs spotted a sentence or paragraph with strong similarities, it was usually easy to confirm or disconfirm the text as plagiarism by looking for indenting, slightly misplaced quotation marks, or a reference to the source and by comparing the density, volume and sequence of the "original" against the student's text.
Taking into account experimental observations as well as first principle and molecular dynamics calculations, it captures both the cd-Si → β-Si transition upon compression and the β-Si → a-Si transition upon rapid decompression, which are most relevant for indenter loading.
I've learned such terms as "dibbler" (a grid-like device of wood and screws for indenting each cell of the seedling packs with a hole for the seeds), "fishing" (when the seedlings are fertilized just before transplanting to the ground by an organic compound of leftover fish parts), and "hardening off" (when the seedlings are tempered to the outside climate for a few days before transplanting).
The critical parameter for determining between JKR and Hertz is the ratio of load to pull-off force 5 For indenting the flat and curved specimens at a load of 1000 μN these ratios are 4.1 and 20.2, respectively.
If you're typing, use a dignified font and follow your teacher's rules for indents and margins.
The representative values should also be a function of material properties, not only indenter angle for sharp indenter and indentation depth for spherical indenter.
The computations reveal that pile-up of the graded alloy around the indenter, for indentation with increasing yield strength beneath the surface, is noticeably higher than that for the two homogeneous reference materials that constitute the bounding conditions for the graded material.
