The most of fine coal particles, with the particle size less than 0.2 mm or 0.3 mm, should be removed from the coal slurry in the feeding.
The limits of the use of computer-guided piezocision are set by the maximum deviation observed; thus a safety distance of 1.5 mm should be considered, which confirms that this innovative technique is clinically applicable.
To reduce the draft force and soil surface disturbance, a tool cutting width of 200 or 300 mm should be used and injecting should be performed as shallow as practical.
The extension lines should not touch the outline of the drawing feature and a small gap of about 2 3 mm should be left, depending on the size of the drawing.
It was found that the nozzle exit position NXP = 5 mm and nozzle diameter d > 1.3 mm should be used to improve the flow organization and premixed combustion for the designed ejector.
In particular, the stability zone for 1 cm particles are much larger than for 1 mm-sized particles, due to the reduced relative importance of the solar radiation pressure, while particles smaller than 1 mm should be almost completely swept away by this perturbation.
Thus, gaps and fissures too small for the injection of filler containing grouts (width b < 1 mm) should be consolidated with a thickened nanosol.
Evidence suggests (with one exception) that any segment of the oesophagus containing air with a diameter of >10 mm should be considered abnormal (Fig. 3a).
Ulnar styloid fractures at its base with initial displacement more than 2 mm should be treated with open reduction and internal fixation [11, 20].
Some studies suggested that 2 mm should be considered the threshold for identifying mucosal thickening [20], and thus the prevalence of slight mucosal thickening may have been underestimated.
Part-solid nodules, especially those in which the solid component is larger than 5 mm, should be considered malignant until proven otherwise, provided either growth or no change is seen at the 3-month LDCT follow-up.
