However, the highest value appeared in the buffer regions of 25-30 km because of the influence of other factors.
As seen in Figure 3, clusters of NTDs were often seen in the buffer regions of 0-6 and 7-12 km during the study period.
The buffer regions of coal mine zones were built into the GIS environment, with buffer distances of 6, 12, 18, 24, 30, or 42 km.
However, folic acid supplementation did not play a role in reducing the rate in the buffer regions of 0-6, 19-24, and 31-42 km.
The NTDs rates in the buffer regions of 7-12, 13-18, and 25-30 km decreased significantly due to folic acid supplementation.
So Kruskal-wallis test was used to compare the average rates of NTDs in the various buffer regions of coal mines.
The number of sequence markers in these chunks including buffer regions of 0.25 MB averaged 24,000 with a range from 10,000 to 35,000, and the number of HD markers averaged 800 with a range from 357 to 1039.
The buffer region of 0-6 km is the area close to the coal mines.
In general, the algorithm tries to maintain a narrow buffer region of control by keeping the operating point (e r,e m ) close to (t h r,t h m ).
Many of the villages in the buffer region of 7-12 km are located at high altitudes and located at significant distances from rivers.
