... that the user applies to the tissue. The depth of palpation, the force used to achieve that depth, and the thickness of the tissue obtained from a computed tomography scan of the abdomen were used to calculate the stiffness properties of each individual layer of tissue. Some experimental data obtained by curve...

... required to squeeze the drug from each bottle was measured, tensile testing was performed on the bottle wall, and stiffness of the nozzle tips was studied via bend testing. The thickness of the bottle walls and the inner diameter (ID) of the nozzles were also recorded. The work required to expel the drug...
