| Generally described, the dual air-current burner consists of two cylindrical tubes of different diameters and different lengths. |
| As a nice touch, Zoch includes two cork balls with different diameters which varies the skill level of the game significantly. |
| Information on aperture type, exine sculpturing and the diameters of pollen grains were cited from Liang. |
| The inner diameters of the seals were adapted to the diameters of the basal parts of root systems and adjusted by screws. |
| Root diameters at these positions along the roots were then measured using a vernier microscope. |
| We used three multimode fibers with different core diameters, namely, 50, 100, and 200 m, for collecting fluorescence. |
