Epithelial cells migrate upward and downward the axis starting from the stem cell pools anchored adjacent to the crypt basis with a migration out of the crypt onto upper areas.
It involves flipping four times, while the body also spins five complete rotations on a sideways or downward-facing axis.
This system was calibrated before each session such that the positive x-axis was rightward, the positive y-axis downward and the positive z-axis was into the screen (all from the participant's perspective), with the origin in the left top corner of the screen.
The etching started from the corner of top-end hexagonal surface of microrods and in overall eroded downward along [0001] axis.
For the FEM calculations, we divided Japanese islands into six cuboids (target zones) because of computer capacity limitations, taking the N90E or N110E direction as the x-axis, the N0°E or N20°E direction as the y-axis, and the vertical downward direction as the z-axis (Fig. 1).
The longitudinal direction of the TPM is set as x-axis, outer normal direction of cross section is set as y-axis and vertical downward direction is set as z-axis which is selected as force hammer stimulating direction.
Well, remember, phi is the angle downward from the z axis.
In infrared spectra the absorption peaks point downward because the vertical axis is the percent transmittance of the radiation through the sample.
Human ageing is inevitably associated with declining function in later years; however, at all life stages, humans can move upward or downward on the vitality/apathy axis.
The vertical downward direction of Z-axis was used as a reference.
As expected, sections with a higher percentage of longitudinal reinforcement had a higher shear capacity, which can be attributed to a combination of additional dowel action (Taylor 1972, 1974), tighter shear cracks and thus an increase in aggregate interlock, and a larger concrete compression zone due to a downward shift of the neutral axis.
