Hence, two samples were prepared in this study, that is, the compressed induration of the expandable material with high water content and the compressed induration after grouting the expandable material with high water content prepared according to the distribution characteristics of the slurry in the borehole and coal mass into the broken coal mass (as shown in Figure 4).
An induration of broken coal masses bound with expandable material with high water content was 40 mm high, with a diameter of 50 mm, representing the strength of the induration after the slurry was injected into the borehole (as shown in Figure 5(b)).
(5) Perineal nodular induration (PNI) also known as biker's nodule, cyclist's nodule, ischiatic hygroma, third testicle, or an accessory testicle is a benign pseudotumour that presents most commonly in avid male cyclists with repetitive perineal microtrauma.
Treatment failure - less than 25% reduction in size of; lesion with persisting induration or increase in size of lesion.
Results of tuberculin skin test in our study showed that all 113 cases having infiltration in their chest x-ray were tuberculin positive (indurations greater than 10 mm).
There were statistically significant more cases of wound indurations, discharge, erythema in control group (p=0.043).
(%) 15/14 (52/48) 9/9 (50/50) PPD: mean maximal induration, cm (range) 17.9 (0-32) 14.5 (0-45) Variable p value Mean age, y (range) <0.001 Male/female, no.
The rate of infection was much higher, with 12% of the group (102) showing a tuberculin skin test (TST) induration of at least 10 mm.
Although the NPC group had the lowest overall percentage of negative Mantoux results, it had the highest percentage of patients who had no reaction at all (i.e., 0-mm induration).
In a Quebec cohort of 1198 foreign-born children and young adults, prior BCG vaccination could account for 50% of PPDs with induration of 5 to 9 mm, but only 4% of reactions 10 mm or greater.
Induration was measured independently by two study nurses at 48-72 hours, and an average of these two readings was used in data analysis (mean inter-reader variability was [is less than]0.3 mm).
In that event there is an area of erythema but no definite palpable border of induration can be found.
