21. Each plate carried three basic shades, carefully graduated to merge across the longer, horizontal plane . 22. Gaucher also extended colour band painting to include works of horizontal planes of contrasting colour. 23. In this technique a 3D digital model is sliced by a set of horizontal planes . 24. His priorities were on a vertical plane; ours are too often on a horizontal plane . 25. These were mounted on a common platform that could be rotated in the horizontal plane . 26. This was due to a horizontal plane fracture that had slowly grown over the years. 27. For horizontally arranged drivers, the lobing phenomenon would be observable in the horizontal plane ." 28. The concept of using a liquid to create or find a horizontal plane is not new. 29. The cells are built randomly within the layers, which are horizontal planes of clusters of cells. 30. Viewed from a horizontal plane the railway line at this point has a gradient of 1.80.
