Both the Cu and Zn were highly abundant in the residual fraction (65.93% and 80.08%), implying that they were not derived from anthropogenic sources but have lithogenic origin. The average potential mobility of Ni was 51.30%. High potential mobility indicates high reduction in concentration soil.

The arithmetic mean of the numbers 7, 6, 5, 4 , 9, 1 and 10 is ¯ y = 7+6+5+4+9+1+10 7 = 42 7 =6 The arithmetic mean is calculated by adding together all of the data values and then divid-ing by the number of values. The mean takes account of all of the data but it can be affected by a few very large values which may distort the average. Mode

for high speeds for spindle bearings If the double direction axial angular contact ball bearing is replaced by two high speed axial bearings BAX, the radial rigidity is preserved in full. The axial rigidity is at the level of the bearing arrangement variant with the spindle bearings. In terms of possible maximum speed, however, the bearing

FF is a high-speed, high-definition, and low-heat machining process that combines high spindle speeds with precisely controlled, high-pressure coolant or forced air to blast away chips and prevent heat buildup in both workpiece and tool. To create a smooth, more uniform surface, the f/P adjusts feedrate equally to pick rate. Makino, Mason, Ohio.
